Abstract
Ophthalmological conditions are underreported in patients with KBG syndrome, which is classically described as presenting with dental, developmental, intellectual, skeletal, and craniofacial abnormalities. This study analyzed the prevalence of four ophthalmological conditions (strabismus, astigmatism, myopia, hyperopia) in 43 patients with KBG syndrome carrying variants in ANKRD11 or deletions in 16q24.3 and compared it to the literature. Forty-three patients were recruited via self-referral or a private Facebook group hosted by the KBG Foundation, with 40 of them having pathogenic or likely pathogenic variants. Virtual interviews were conducted to collect a comprehensive medical history verified by medical records. From these records, data analysis was performed to calculate the prevalence of ophthalmological conditions. Out of the 40 participants with pathogenic or likely pathogenic variants, strabismus was reported in 9 (22.5%) participants, while astigmatism, myopia, and hyperopia were reported in 11 (27.5%), 6 (15.0%), and 8 (20.0%) participants, respectively. Other reported conditions include anisometropia, amblyopia, and nystagmus. When compared to the literature, the prevalence of strabismus and refractive errors is higher than other studies. However, more research is needed to determine if variants in ANKRD11 play a role in abnormal development of the visual system. In patients with established KBG syndrome, screening for misalignment or refractive errors should be done, as interventions in patients with these conditions can improve functioning and quality of life.

Abstract
BACKGROUND Panoramic radiographs (PRs) are used in the detection and diagnosis of developmental dental anomalies and pathologies (DDAPs) in children. AIM The primary objective of this observational cohort study was to evaluate the age-based prevalence of DDAP on PRs, whereas the secondary objective was to determine a threshold age for the detection of DDAP to provide supportive evidence for the prescription of PR in paediatric dental practice. DESIGN The study examined diagnostic PRs from 581 subjects aged 6 to 19 years. All PRs were reviewed by experienced, calibrated, masked examiners for the identification or presence of anomalies in size, shape, position, structure, and other developmental anomalies and pathologies (ODAP) of the face-neck region in a standardized condition. The data were statistically analyzed for interpretation. RESULTS Overall, 74% (n = 411) of the cohort had at least one anomaly (shape anomaly: 12%, number anomaly: 17%, positional anomaly: 28%, structural anomaly: 0%, and ODAP: 63%). The optimal Youden index cutoff for any anomaly was 9 years. Twelve and 15 years also showed predictive ability. CONCLUSION The results suggest that PRs should be prescribed at ages 9, 12, and 15 years for the diagnosis of DDAP.

Abstract
To investigate the distribution of dental anomalies between non-syndromic orofacial cleft patients and their association with the cleft type and gender. Retrospective cross-sectional study involving examination of intraoral dental records and radiographs. 300 non-syndromic orofacial cleft patients included (161 males and 139 females, mean age: 10.23 ± 2.3 years). Variables analyzed: tooth agenesis, microdontia, and supernumerary teeth. Data analysis: Chi-square and Fisher's exact tests to investigate the correlation between dental anomalies, cleft type, and gender. Agenesis occurred in 66% of the subjects, supernumerary teeth in 19.6%, and microdontia in 18.3%. In females with unilateral left cleft lip and palate (CLP), agenesis was significantly higher compared to males. Both genders presented significant agenesis of maxillary lateral incisors and right central incisor. Significant agenesis of central incisor, canine and second premolar on the upper left side and lower second premolars were observed only in males, with significant microdontia for maxillary lateral incisors and left central incisor. Significant agenesis of maxillary first premolars was seen only in females. Agenesis in maxillary quadrants was significant for patients with unilateral right and left CLP, and bilateral CLP. In mandibular quadrants, agenesis was substantially higher for patients with isolated CP. Results suggest that tooth agenesis and microdontia might not be directly associated with the cleft area's anatomical irregularity but are affected by gender and other genetic factors that regulate the development of the anomaly and the orofacial clefting mutually.

Abstract
OBJECTIVE The aim of this study was to assess the frequency of mandibular second premolar (MnP2) distoangulation among orthodontic patients and the angular changes after a longitudinal follow-up. METHODS The sample was collected from the orthodontic records of 865 patients. The distoangulation group was composed of 42 patients (mean age 9.29 ± 1.24 years, 16 male, 26 female) with distoangulation of MnP2. The control group was composed of 32 patients (mean age 9.38 ± 1.10 years, 15 male, and 17 female) without distoangulation of MnP2. Panoramic radiographs taken in the mixed (T1) and the early permanent dentition (T2) were analyzed in both groups. Longitudinal angular changes (distal angle θ and premolar-molar angle γ), degree of root formation, second premolar depth, and prevalence of associated dental anomalies were analyzed. Intergroup comparison was performed with Mann-Whitney, t-tests, and chi-square tests (P < 0.05). RESULTS The prevalence of MnP2 distoangulation in the mixed dentition was 4.85%. The distoangulation group showed a smaller initial distal angle (59.34o ± 8.41) when compared to control group (79.88o ± 7.60). The spontaneous eruption of the MnP2 with distoangulation was observed in 76.57% of the sample. MnP2 distoangulation was significantly associated with agenesis of its antimere, small maxillary lateral incisors, and deciduous molar infraocclusion. LIMITATIONS Severe cases of MnP2 distoangulation were absent in this study. CONCLUSIONS The frequency of MnP2 distoangulation among orthodontic patients was 4.85%. Mild to moderate distoangulated Mnp2 spontaneously uprighted from the mixed to the permanent dentition. Small lateral incisors, second premolar agenesis, and infraocclusion of deciduous molar were frequently found in cases with MnP2 distoangulation.

Abstract
INTRODUCTION Despite researchers' recent interest in identifying links between some dental and craniovertebral abnormalities, there are many important, unassessed gaps in our knowledge of this matter. In addition, previous samples were small. This large study aimed to examine, for the first time, the occurrence/severity of numerous dental and skeletal anomalies or variations and their correlations with each other and with growth patterns. METHODS This epidemiological study was conducted on pretreatment radiographs of 1194 patients from 3 cities (815 females). Skeletal sagittal skeletal relationships and vertical growth patterns were determined. The occurrence/severity were assessed for: cervical vertebral fusion (CVF), atlas posterior arch deficiency (APAD), ponticulus posticus (PP), sella turcica bridging (STB), hypodontia, oligodontia, hyperdontia, missing of maxillary laterals, microdontia, macrodontia, root dilaceration, odontoma, taurodontism, dental fusion, dental gemination, enamel pearl, permanent molar ankylosis, primary molar ankylosis, dens in dente, dens invaginatus, dental impaction, ectopic eruption, and dental transposition. Incidental findings were recorded as well. Concurrent anomalies, sex dimorphism, and correlations across variables were examined statistically, adjusting for the false discovery rate (α = 0.05). RESULTS Prevalence was calculated for 43 dentoskeletal traits/anomalies (22 abnormalities/variations [plus their severities/types] as well as 21 incidentally found traits/anomalies). Dental impaction may be more common in hyperdivergent and severer cases of sella bridging; also, primary molar ankylosis was associated with missing teeth. Dental impaction was associated only with STB and not with PP, APAD, or vertebral fusion. The only association observed among the four skeletal anomalies was seen between APAD and CVF. Merely the variables 'sagittal skeletal relationships, vertical growth patterns, PP, and APAD' showed sexual dimorphism; of these, only vertical growth pattern and APAD remained sexually dimorphic after adjusting for the FDR; still, the other two remained marginally significant and worth further evaluations. Sex dimorphism did not exist in concurrent abnormalities. The skeletal Class III was associated with the concurrent occurrence of craniovertebral, dental, and dentoskeletal abnormalities. Skeletal Class I was associated with fewer occurrences of concurrent dental anomalies. Vertical growth patterns were not associated with concurrent dental or dentoskeletal anomalies. However, the hyperdivergent pattern was associated with fewer cases of concurrent craniovertebral abnormalities. CONCLUSIONS STB and hyperdivergent pattern were associated with dental impaction. However, APAD, CVF, or PP were not associated with dental impaction. APAD was associated with CVF. Sexual dimorphism existed conclusively in the case of vertical growth patterns and APAD. Concurrent abnormalities (dental, skeletal, and dentoskeletal) were associated with skeletal Class III.

Abstract
Purpose: To assess the prevalence and severity of and describe dental anomalies in children treated for acute lymphoblastic leukemia (ALL) under recent Dana-Farber Cancer Institute (DFCI) protocols. Methods: Patients aged between 14 and 25 years old having received a diag- nosis of ALL before the age of 11 years and after September 2000 received clinical and radiographic oral examinations. Results: Dental anomalies were observed in 26 (51.0 percent) of 51 subjects. Microdontia was the most prevalent dental defect (39.2 percent). Impacted permanent second molars were observed in five (9.8 percent) patients. Being age five years or younger at diagnosis significantly increased the prevalence and severity of dental anomalies (P<0.001). Conclusions: Recent DFCI protocols showed a decreased prevalence of dental disturbances. The anomalies observed may still alter the development of the dental arches and occlusion in pediatric ALL survivors. Further research is needed to confirm the association between ALL treatment and permanent second molar impaction.

Abstract
BACKGROUND Molar-root incisor malformation (MRIM) is a rare dental anomaly featuring constricted cervical margins and tapered, narrow root and pulp morphology, often associated with severe toothache and infection. AIM The aim of this study was to determine the prevalence of MRIM in children seen in a specialist paediatric dental unit of a tertiary referral hospital and to describe the characteristics of affected individuals. DESIGN This study was an audit of children attending from November 2020 to November 2021. Radiographs were used to identify individuals with MRIM, and clinical data were collated. In addition, histology and microcomputed tomography (microCT) imaging were performed on teeth extracted from an affected individual. RESULTS The prevalence of MRIM was five cases of 1054 children examined (0.47% or 1:210). The permanent first molars were affected in all five children and the primary second molars in two children; all children had medical comorbidities and multiple exposures to general anesthesia before 4 years of age. In addition, histological and microCT analyses displayed numerous microchannels connecting the pulp chamber to the external surface of the tooth at the furcation. CONCLUSIONS Molar-root incisor malformation is an uncommon dental anomaly affecting paediatric patients with multiple comorbidities and is characterized by porosities extending from the pulp chamber to the external tooth surface, predisposing the risk of bacterial ingress from the oral cavity into the pulp chamber. Early detection may prevent atypical odontogenic facial pain and infection.

Abstract
BACKGROUND The aim of this study was to determine whether there is any association between molar incisor hypomineralization and developmental dental anomalies. METHODS Two pediatric dentists evaluated panoramic radiographs of 429 children aged 8-14 years with molar incisor hypomineralization (study group) and 437 children without molar incisor hypomineralization (control group) in terms of developmental dental anomalies. Twelve different developmental dental anomalies were categorized into four types: size (microdontia, macrodontia); position (ectopic eruption of maxillary permanent first molars, infraocclusion of primary molars); shape (fusion, gemination, dilaceration, taurodontism, peg-shaped maxillary lateral incisors); and number (hypodontia, oligodontia, hyperdontia) anomalies. RESULTS No significant difference was observed in the frequencies of developmental dental anomalies between the study and control groups in total, females, and males (p > 0.05). A statistically significant difference was found between the distribution of developmental size, position, shape, and number anomalies between the study and control groups (p = 0.024). The most common anomaly in both groups was hypodontia (6.3% and 5.9%, respectively). There was a significant difference between the study and control groups in terms of subtypes of shape anomaly in all children and females (p = 0.045 and p = 0.05, respectively). CONCLUSIONS While a significant difference was observed between the distributions of types of developmental dental anomalies between individuals with and without molar incisor hypomineralization, there was no difference in terms of the frequency of developmental dental anomalies.

Abstract
OBJECTIVES This study aimed to investigate the clinical characteristics of congenital deciduous teeth absence and its permanent teeth performance type by using panoramic radiographs. METHODS A total of 15 749 panora-mic radiographs of 3-6-year-old children with deciduous dentition were collected from January 2020 to December 2021. The incidence of congenital deciduous teeth absence was observed, and the abnormality of permanent teeth was recor-ded. SPSS 24.0 software was used for statistical analysis. RESULTS The incidence of congenital deciduous teeth absence was 2.54% (400/15 749), which was found in 217 girls and 183 boys, and the difference between the genders was statistically significant (P=0.003). The absence of one and two deciduous teeth accounted for 99.75% (399/400) of the subjects. In addition, 92.63% (490/529) of mandibular deciduous lateral incisor was congenitally absent, 44.80% (237/529) of deciduous teeth was absent in the left jaw, and less than 55.20% (292/529) was absent in the right; the difference between them was statistically significant (P=0.017). The absence of 96.41% (510/529) deciduous teeth in the mandibular was significantly more than that of 3.59% (19/529) in the maxillary, and the difference between was statistically significant (P=0.000). Furthermore, 68.00% (272/400) and 32.00% (128/400) of deciduous teeth were absent in unilateral and bilateral, respectively, and the difference was statistically significant (P=0.000). Four types of congenital deciduous teeth absence with permanent teeth were observed as follows: 1) 73.91% (391/529) of permanent teeth was absent; 2) 20.60% (109/529) of permanent teeth was not absent; 3) the number of fused permanent teeth accounted for 4.91% (26/529); 4) the number of supernumerary teeth was 0.57% (3/529). CONCLUSIONS Although the absence of congenital deciduous teeth is less common than that of permanent teeth, it affects deciduous and permanent teeth to some extent. Dentists should pay attention to trace and observe whether abnormalities are present in the permanent teeth and take timely measures to maintain children's oral health.

Abstract
BACKGROUND Sex dimorphism has been implicated in oral health differences and the pathogenesis of oral diseases, such as tooth agenesis, periodontal disease, dental caries, and tooth loss. Tooth agenesis (TA) is one of the most common developmental anomalies in humans, and its prevalence and patterns are different across ethnic groups. The aim of this study was to investigate the phenotypes and sex-associated patterns of nonsyndromic tooth agenesis (TA) in Thai dental patients. METHODS One thousand ninety panoramic radiographs were examined. One hundred and one subjects (37 males, 64 females, 15-20 years-old) with nonsyndromic TA were evaluated. Differences in TA prevalence between groups were analyzed using the chi-square or Fisher exact test. RESULTS The TA prevalence, excluding third molars, was 9.3% and more frequently found in the mandible compared with the maxilla. The maxilla demonstrated a higher prevalence of first premolar agenesis than the mandible (P = 0.012), while the mandible had a higher prevalence of second premolar agenesis than the maxilla (P = 0.031). There were significantly more males missing one tooth than females, however, there were more females missing two or more teeth than males (P = 0.042). A missing maxillary left lateral incisor was significantly more frequent in males (P = 0.019), while a missing mandibular right lateral incisor was more frequent in females (P = 0.025). In females, the pattern of two mandibular lateral incisors agenesis was the most common and significantly present in females more than males (P = 0.015). In contrast, the pattern of one mandibular left lateral incisor agenesis was only observed in males and significantly found in males more than females (P = 0.047). CONCLUSIONS We demonstrate sex-associated differences in nonsyndromic tooth agenesis. The prevalence of single tooth agenesis was higher in males, while that of two or more teeth agenesis was higher in females. We found different patterns of lateral incisor agenesis between males and females.

Abstract
OBJECTIVE This study aimed to investigate the prevalence and extent of dental developmental complications in patients who have undergone pediatric hematopoietic stem cell transplantation (SCT) and identify the risk factors. MATERIALS AND METHODS We retrospectively investigated the clinical data warehouse of the Catholic Medical Center information system for identifying patients who: 1) visited the Department of Pediatrics between 2009 and 2019, 2) underwent SCT under the age of 10, and 3) had panoramic radiographs. Thus 153 patients were included in this study. The prevalence and extent of tooth agenesis, microdontia, and root malformation were assessed using panoramic radiographs obtained after SCT, and the risk factors were analyzed using regression analysis. RESULTS All 153 patients had at least one dental anomaly. When grouped according to the age at initial chemotherapy (≤ 2.5; 2.6-5.0; 5.1-7.5; > 7.5 years), the prevalence of agenesis showed statistically significant differences among the different age groups (P < 0.001). The prevalence of agenesis was highest in the youngest age group. As the initial age at chemotherapy increased, the number of affected teeth per patient decreased for all three anomalies. The location of the affected tooth was also influenced by the age at initial chemotherapy. Regression analysis demonstrated that young age at initial chemotherapy was a risk-increasing factor for tooth agenesis and microdontia. CONCLUSIONS The age at initial chemotherapy may be a critical factor in determining the type, extent, and location of dental complications after SCT. These results suggest that careful dental follow-up and timely treatment are recommended for pediatric patients undergoing SCT.

Abstract
OBJECTIVE To determine the prevalence, frequency and distribution of dental anomalies that were detectable on panoramic radiographs in a large sample Turkish population, and the associations among the anomalies. METHODS This study was conducted retrospectively on panoramic radiographs of 43,880 patients who were admitted to the Faculty of Dentistry at Trakya University, Edirne, Turkey. Patients' files were examined by two observers and radiographic images of 2265 patients with at least one dental anomaly were included. Dental anomalies were classified as anomalies in the number, structure, position and shape of teeth. The interactions between the groups were analysed using chi-square tests. RESULTS The study group consisted of 1336 women (59%) and 929 men (41%) with a mean age of 33.3 ± 14.4 years. A total of 2265 patients, with a prevalence of 5.2% (2265/43880), had at least one dental anomaly. The most frequent anomalies were in position (2.7%) and number (2.1%). Structure anomalies were least common, affecting 0.02% of patients. Among the study group of patients with dental anomalies, 12.2% presented more than one kind of anomaly. CONCLUSION Position anomalies were the most common dental anomaly, whereas structural anomalies were least common in a Turkish sample. The prevalence of anomalies varies between populations, confirming the role of racial factors.

Abstract
This study's objective was to compare the total and outside the cleft prevalence of dental anomalies (DA) between patients with cleft lip and palate (CLP) and a control group. This retrospective cross-sectional study was done under a case-control design. The case group consisted of 192 non-syndromic patients with complete CLP, while the control group included 411 patients. All subjects had orthopantomography, intra, and extraoral photographs. The prevalence of dental agenesis, supernumerary teeth, impacted teeth, dental transposition, and microdontia were compared using a chi-squared test (P < .05). Next, a second test was made, but only the anomalies outside the cleft were considered for this study. Total prevalence was 89.1% for cases, and 20.9% for controls (P < .01). The prevalence of each DA was significantly higher for the case group. In the analysis of DAs outside the cleft, the total prevalence was still significantly associated (P < .01); however, only dental agenesis was statistically significant (P < .01). Further analysis found that a high rate of upper premolar absence (P < .01) could explain this event. Patients with CLP have a higher prevalence of DAs compared to controls. After considering only the DAs outside the cleft, the total prevalence remains significantly higher. However, this phenomenon is explained mainly by the elevated prevalence of upper premolars' agenesis. This study's results suggest that environmental factors are behind the high prevalence of DAs in subjects with CLP.

Abstract
BACKGROUND Dental anomalies are craniofacial abnormalities in the size, structure or number of the teeth. This study was conducted to assess the prevalence of dental anomalies among children aged 0-16 years attending the Paediatric Dental Clinic at the Lagos University Teaching Hospital, Lagos, Nigeria. METHODS A cross-sectional design was used and data were obtained from the dental records of the Dental Clinic from January 2014 to August 2019 by two calibrated examiners, who are co-authors of the manuscript. To test for statistical differences, Chi-squared test was utilised for the categorical variables. The prevalence of the different dental anomalies was estimated and presented with frequencies. P < 0.05 was considered statistically significant. RESULTS Among the 6175 patients' dental records reviewed, 50.85% (n = 3150) were male and the highest proportion of 45.4% (n = 2807) were aged between 6 and 10 years, with a mean age of 8.62 ± 3.85 years. A total of 1090 (17.52%) had dental anomalies; 465 (7.53) anomalies were in the maxilla, 263 (4.6) were in the mandible while 360 (5.83) were in both. The most common anomaly was hypoplasia 550 (9.06%), followed by retained primary tooth 546 (8.84%) and hypodontia 84 (1.36%). Dentinogenesis imperfecta 1 (0.02) and transposition 1 (0.02) were the least prevalent anomalies. Retained primary teeth (5.8%) and the cusp of Carabelli (0.4%) were slightly more prevalent among males. However, females had a higher prevalence of natal/neonatal teeth (0.4%), fusion/germination (0.4%), hypodontia (1.5%) and peg-shaped lateral incisors (0.9%). CONCLUSION Dental anomalies' prevalence in this study was 17.52%, with a higher occurrence of anomalies in the maxilla. Hypoplasia was the most prevalent anomaly, after which was retained primary tooth, then hypodontia. Prompt diagnosis and preventive interventions are crucial for the appropriate management of these dental anomalies.

Abstract
Purpose: The purpose of this study was to describe the prevalence of radiographically identifiable developmental dental anomalies (DDA) in a university-based pediatric dental clinic and to assess for associations between DDA and health status. Methods: Retrospective data, obtained from the electronic dental records of a three-year pediatric patient cohort, were evaluated by two trained and calibrated examiners. Strict inclusion/ exclusion criteria were applied. A validated image quality grading system was used for radiograph assessment, and the physical status classification of the American Academy of Anesthesiology was utilized. A chi-square test and bivariate logistic regression were used for statistical analysis. The inter- and intraexaminer reliability was assessed using Cohen's Kappa. Results: A total of 1,478 subjects (69 percent medically healthy) were enrolled. DDA were identified in 25 percent of the subjects, with hyperdontia, hypodontia, and microdontia being more common. A statistically significant association was found between the presence of DDA and health status (P<0.001) and between DDA and asthma (P=0.035). Patients with systemic disturbances showed 2.12 times greater odds of having DDA (P<0.001, 95 percent confidence interval equals 1.7-2.7). Conclusions: The prevalence of developmental dental anomalies was high, with one in four patients affected. DDA in number were the most common. Patients with systemic disturbances had greater odds of having DDA.

Abstract
OBJECTIVE To estimate the prevalence of short root anomaly (SRA) in a group of Puerto Ricans at the Advanced Education Program in Orthodontics of the University of Puerto Rico. METHODS A cross-sectional study was conducted with digital panoramic x-rays of 203 patients (112 females and 91 males; mean age: 17 years) in Puerto Rico. Utilizing the modified Lind's method, 406 maxillary right and left central incisors (1) were measured and evaluated for SRA. Root and crown length and R/C ratio were compared by sex and side. Linear regression was used to evaluate the associations between the R/C ratio and age, sex, and side (right/left). All the statistical analyses were evaluated using significance level of .05 (2). RESULTS The prevalence of SRA was 0.49%. The average root and crown lengths for the maxillary right and left central incisors were 19.47 and 10.28 mm, respectively. Sex was associated with root and crown length, not with the R/C ratio. No differences were observed in the R/C ratio by the side. There were no significant associations between age, sex, and side and R/C ratio in the multivariate analysis. CONCLUSION The prevalence of SRA in our population is lower than any reported in the literature. The R/C ratio in our Hispanic population was the highest compared with those of other ethnicities. Neither the sex nor the side of the incisor was associated with the R/C ratio. These findings are contrary to those of prior reports stating that males have higher R/C ratios than females.

Abstract
Purpose: The purpose of this study was to evaluate the association between dental anomalies of the permanent dentition and autism spectrum disorder (ASD). Methods: The dental and medical records and panoramic radiographs of 200 six- to 17-year-old subjects with a diagnosis of ASD were assessed retrospectively. The controls were 200 age- and gender-matched healthy children. The individual counts of shape, number, and positional dental anomalies and the total counts of all anomalies were recorded. Medical comorbidities were defined and documented as two subgroups: ASD subjects with (ASD-C) or without (ASD-NC) comorbidities. Results: Seventy-seven percent of ASD subjects had at least one comorbidity. Sixty-five percent of ASD subjects demonstrated at least one dental anomaly in comparison to controls (53 percent). There were no significant differences for the prevalence of number, shape, positional, or total anomalies between control, ASD-C, or ASD-NC groups. The ASD-NC group had a significantly higher proportion of pyramidal molars (P=0.02) and ectopically erupting teeth (P=0.04) when compared to controls. Conclusions: There were no significant differences in prevalence for shape, number, or positional anomalies in the permanent dentition between autism spectrum disorder subjects and healthy controls. The prevalence of pyramidal teeth and ectopic eruption was significantly associated with ASD.

Abstract
Skulls of 1,901 Eastern Atlantic harbor seals (Phoca vitulina vitulina) were systematically studied for externally visible dental anomalies and lesions. The sample comprised 927 males and 974 female individuals, with age at death ranging between 1 week and 25 years. Most of the skulls originated from animals collected in 1988, when the population suffered from a mass mortality event caused by the phocine distemper virus (PDV). Mean age (± SD) of females (6.7 ± 6.4 years) was higher (p = 0.002) than that of males (5.9 ± 5.2 years). In 264 individuals, one or more teeth were missing either congenitally (n = 26 animals, 1.4%) or due to intravital loss (n = 238 animals, 12.5%). One male exhibited congenital absence of all teeth (anodontia). As this animal had been reported to be almost hairless, the condition was tentatively diagnosed as a case of hypohidrotic ectodermal dysplasia. Males were more frequently (p = 0.002) affected by intravital tooth loss (15.0%) than females (10.2%). Supernumerary teeth were found in 3.4% of the skulls, with females (4.7%) showing hyperodontia more frequently (p < 0.001) than males (1.9%). Fifty-nine individuals (3.1%; 28 males, 31 females, p = 0.84) exhibited abnormal tooth morphology. Tooth fractures were noted in 40 seals (2.1%), with males being more frequently affected than females (p = 0.017). Periapical lesions were diagnosed in 143 skulls, with a tendency (p = 0.05) for males (8.7%) to be more frequently affected than females (6.4%). Enamel hypoplasia was not observed in the study sample. Analyzing the occurrence of dental anomalies and lesions in wild mammals can substantially contribute to an assessment of population health and thereby broaden the basis for effective species conservation and informed management decisions.

Abstract
AIM The aims of the present study were (1) to assess the prevalence of ectopic mandibular canines and (2) to evaluate whether an association exists between maxillary and mandibular canine ectopia. MATERIALS AND METHODS The records of 983 patients (males and females) were divided systematically into two groups: group I (454 patients) (control group) included patients who attended the clinic from September 2013 to August 2014, while group II (529 patients) included patients who attended the clinic from September 2014 to August 2015. Group I was used to assess the prevalence of ectopic mandibular canines in the population, while group II was used to obtain 40 radiographs of ectopic maxillary canines, which comprised group To investigate any association between maxillary and mandibular canines, the prevalence of ectopic mandibular canines was assessed in group Canine positions were assessed as follows: (1) amount of horizontal canine overlap with the adjacent lateral incisor root; (2) the angle between the canine and true vertical. RESULTS The prevalence of ectopic mandibular canines in the population (group I) was 5.3% (24 of 454 patients); in group 22.5% (9 of 40) of maxillary canine cases exhibited ectopic mandibular canines. Group II1 had a significantly higher prevalence of ectopic mandibular canines than did the control group (group I) (p < 0.001). CONCLUSION The prevalence of mandibular ectopic canines was 5.3%. Ectopic mandibular canines were highly associated with ectopic maxillary canines; a quarter of patients with ectopic maxillary canines are expected to have mandibular ectopia. CLINICAL SIGNIFICANCE Dentists should be aware of all dental anomalies, particularly, impacted canines. Early and interceptive management of impacted canines increases the chance of canine eruption.

Abstract
INTRODUCTION Prevalence of dental anomalies in cleft patients is higher than that in general population. The objectives of this study were to assess the prevalence of dental anomalies and their coexistence in French children with cleft and, then, to investigate the relation between the dental anomalies and the cleft type. MATERIAL AND METHODS Seventy-four non-syndromic cleft patients (6-16 years old) from Lille Regional University and Mondor-Chenevier Hospitals (France) were included. Clefts were classified as right/left unilateral cleft lip and palate (UCLP), bilateral cleft lip and palate (BCLP) and cleft palate (CP). Dental anomalies were investigated on panoramic radiographs and categorized as agenesis, supernumerary teeth, incisor rotations, impacted canines and shape anomalies. Prevalence and gender distribution of dental anomalies, mean number of affected teeth per patient, agenesis occurrence and location, and coexistence of dental anomalies were analysed by cleft type. RESULTS 96.0% of patients presented at least one dental anomaly (agenesis 83.8%, incisor rotations 25.7%, shape anomalies 21.6%, impacted canines 18.9%, supernumerary teeth 8.1%). BCLP patients had a higher number of affected teeth, and left UCLP patients had a higher one compared to right UCLP patients. Distribution of inside (45.3%) and outside (54.7%) cleft region agenesis was similar. Adjacent (31.8%) and not adjacent (33.3%) combined dental anomalies were often encountered. CONCLUSIONS Dental anomalies were localized inside as well as outside cleft region and were often associated with each other. BCLP patients were more affected. CLINICAL RELEVANCE Early radiographic evaluation allows a comprehensive diagnosis of inside and outside cleft region anomalies, required for the multidisciplinary dental treatment.

Abstract
PURPOSE Determine the prevalence of pyramidal molars (PMs), associated tooth anomalies, and medical conditions (MC). METHODS Pantomograms from 10,168 subjects were searched for PMs. RESULTS A total of 148 individuals (75.7 percent females), aged 9.7 to 18.9 years old, had PMs. Subjects with MCs (53.4 percent) had on average 17 percent more PMs (P=.0476) and 2.8 times greater odds of palatally displaced canines (P=.0309). The mean number of pyramidal and taurodont molars per subject was 2.9±1.4 (SD) and 3.1±1.7 (SD), respectively. In both sexes, 63.5 percent of all observed PMs were located in the maxilla and 78.5 percent of all PMs were second molars. Taurodont molars increased by 9.4 percent as other tooth anomalies increased by one, but decreased by 8.2 percent for each additional PM. Tooth anomalies associated with PMs were palatally displaced canines (17.6 percent) and short root anomaly of maxillary central incisors (6.1 percent). Delayed eruption was noted in 9.5 percent, tooth agenesis in 6.1 percent, and supernumerary teeth in 3.4 percent. CONCLUSIONS The prevalence of pyramidal molars was 1.4 percent, and the female-to-male ratio was 3.1 to one. Pyramidal molars are often associated with medical conditions and other tooth anomalies.

Abstract
The aim of this study was to investigate the prevalence of third molar agenesis and other associated dental anomalies in Bangladeshi population and to investigate the relationship of other dental anomalies with the third molar presence/agenesis. A retrospective study was performed using panoramic radiographs of 5923 patients, who ranged in age from 10 to 50 years. All radiographs were analyzed by Planmeca Romexis® 3.0 software (Planmeca Oy, Helsinki, Finland). Pearson chi-square and one way ANOVA (Post Hoc) test were conducted. The prevalence of third molar agenesis was 38.4%. The frequency of third molar agenesis was significantly higher in females than males (p <0.025). Third molar agenesis was significantly more prevalent in maxilla as compared to mandible (p <0.007). The prevalence of other dental anomalies was 6.5%, among them hypodontia was 3.1%. Prevalence of third molar agenesis varies in different geographic region. Among the other dental anomalies hypodontia was more prevalent.

Abstract
BACKGROUND Factors that can directly influence the extraction of third molars include the position of the tooth and the presence of root dilacerations. Knowledge of these features favors an accurate therapeutic evaluation of third molars; therefore, the aim of this study was to evaluate, using panoramic radiographs, the positioning of unerupted third molars with and without root dilacerations and to verify a possible association between these two variables. METHODS In this study, 16,136 panoramic radiographs were analyzed, including 1756 lower third molars, in which the positioning was assessed according to the Winter classification and the presence of root dilacerations was determined. The data obtained from the assessments of the frequencies of the positions and the presence of root dilacerations of impacted mandibular third molar was described. A χ2 test was applied to verify a possible association between the variables. RESULTS The results indicated that the most frequent position was mesioangular (44.5%), followed by horizontal (24.9%), vertical (17.4%), distoangular (12.5%), inverted (0.4%), and linguoangular (0.3%). Of the mandibular third molars evaluated, 35% had root dilacerations. The chi-square test revealed a significant association between the position of the tooth and the presence of root dilacerations (P<0.0001, χ2=34.28). The frequency of root dilaceration was statistically higher for the vertical (45.5%) and distoangular positions (40.9%). CONCLUSIONS The mesioangular position was the most prevalent location for lower third molars, and the highest frequencies of root dilacerations were observed in the vertical and distoangular positions. Knowledge about the prevalence of root dilacerations and the significant association between the position of the third molars and root dilacerations will allow safer surgical planning for dental extractions of third molars.

Abstract
Practitioners and policy-makers need information about the relative frequency of dental anomalies among children in their region. This study investigated the prevalence of different oral anomalies among schoolchildren in Sana'a city, Yemen. A sample of 1000 private and public schoolchildren aged 4-12 years were examined by the same examiner using disposable tongue blades. The total prevalence of oral anomalies was 15.1%, most commonly in boys (male:female ratio 3.2:1) aged 7-12 years. The most prevalent dental anomaly related to hard tissues was tooth hypoplasia (2.8%), followed by hypocalcification (2.6%), then microdontia (0.5%), macrodontia (0.4%), hypodontia (0.4%), supernumerary teeth (0.3%), tooth transposition (0.3%), dental fusion (0.2%) and gemination (0.2%). The most prevalent soft tissues anomaly was fissured tongue (4.0%), followed by ankyloglossia (1.8%), geographic tongue (0.9%), macroglossia (0.4%) and hairy tongue (0.3%). Appropriate measures need to be taken early to mitigate the negative impact and later costs of treatment of anomalies.

Abstract
The aim of the study was to assess the significance of environmental risk factors for teeth aplasia and hypoplasia in cleft lip and palate children. Two hundred and forty-seven cleft lip and palate (CLP) children were enrolled in the study including 105 (42.5%) with bilateral CLP and 57.5% with unilateral CLP. The mean age was 11.2±4.9 years. Teeth condition was assessed clinically and radiologically. The impact of risk factors for teeth anomalies was analyzed by retrospective data obtained from computer database (absence of preoperative orthopedic treatment, palatal defects after primary palatoplasty and type of primary procedures). Surgical trauma by early periosteoplasty (at the age of 3-4 months), excessive scarring and tissue traction due to absence of early orthopedic treatment and palatal defect were associated with significantly higher incidence of incisors hypoplasia (both developmental enamel defects and microdentia) and aplasia of central incisors not seen in the other study subgroups. Incisors aplasia and hypoplasia in CLP patients do not always have disembryogenic origin but may depend on external environmental factors, including surgical trauma.

Abstract
Epidemiology of dentoalveolar anomalies is undoubtedly important, but in terms of the organization of orthodontic care, greater interest are data on the needs in this type of treatment. In a situation of limited manpower and resources for the provision of orthodontic care information about needs in orthodontic treatment allows you to define a group of patients with the primary need for orthodontic treatment, and to identify priorities to optimize the organization of orthodontic care in the region. Such data can be obtained by using the Dental Aesthetics Index (DAI) and Index of Orthodontic Treatment Need (IOTN). The aim of the study was to analyze the epidemiology of various forms of dentoalveolar anomalies school-age children of Kirishi district of Leningrad region, as well as their needs in orthodontic treatment in accordance with objective evaluation indices. The study involved 734 pupils of Kirishi lyceum №1 of Leningrad region. Analysis of the prevalence of dentoalveolar anomalies, as well as needs in the orthodontic treatment was conducted in three age groups: I mixed dentition period (6-9 years), II mixed dentition period (10-13 years), and permanent dentition (14-17). To determine the needs in the orthodontic treatment were used two most common international index (DAI and IOTN). In Kirishi district of Leningrad region dentoalveolar anomalies were found in 88.8% of children of school age, which is in accordance with the indices and IOTN DAI needs in orthodontic treatment is 38.8% and 54.5%, respectively. In order to reduce unnecessarily high load volume medical institutions orthodontic profile, optimize utilization of financial resources, as well as reducing social tension it is recommended to introduce the practice of doctors-orthodontists methodology for determining the needs in orthodontic treatment by objective indices.

Abstract
PURPOSE The purpose of this study was to determine, from a large number of panoramic images taken in the clinic of a pediatric dentistry residency program, the prevalence of maxillary nine-year molars (9YM), associated medical conditions (MCs), and the presence of coexisting tooth anomalies (TAs). METHODS Pantomograms from 13,140 patients were searched for 9YM. Radiographs from identified subjects were examined for coexisting TAs, and charted MCs were noted. For identified 9YM, Nolla's stage of tooth formation was determined and the subjects' dental ages were calculated. RESULTS Among 53 subjects (68 percent females), 21 unilateral and 32 bilateral cases of 9YM occurred. Females and males were of similar age (7.98 versus 7.91 years old). Overall dental and chronological ages were significantly different: dental development in bilateral cases was delayed by 4.1 months in females and 2.9 months in both sexes (P=.003). In unilateral cases, it was accelerated by 3.6 months in females and 3.5 months in males. The specific tooth age for all 9YM was 4.95 years for females and 5.56 years for males (P=.018). The average count of associated findings (e.g., missing teeth, peg laterals, other TAs, and other eruption delays) was 0.62 in unilateral and 1.44 in bilateral cases (P=.02). Commonly associated MCs included clefting (<small>N</small> equals five), and Down syndrome (n equals three). CONCLUSIONS The prevalence of nine-year molars was one in 248 (0.4 percent), and the average delay in dental development was 2.7 years.

Abstract
OBJECTIVE This study aims to investigate the prevalence and distribution of teeth number and morphology abnormalities in Chinese pediatric patients' permanent teeth at the mixed dentition stage by performing panoramic radiographs analysis. METHODS A total of 4 347 panoramic radiographs of pediatric patients aged 5 years to 15 years who were admitted to the hospitals from September 2011 to September 2013 were reviewed. The presence of teeth number and morphology abnormalities were recorded as follows: congenitally absent teeth, supernumerary teeth, odontoma, microdontia, fused teeth, dilaceations, and cusp deformity. SPSS 16.0 software was used for statistical analysis. RESULTS The prevalence of teeth number and morphology abnormalities in pediatric patients' permanent teeth was 31.79% (1,382/4,347). The prevalence was higher in males. Significant difference between the genders was observed (P < 0.05). Tooth agenesis, the most frequent dental anomaly (15.00%, 652/4,347), was considerably common in females; supernumerary teeth (12.61%, 548/4,347) followed, which was significantly common in males. Both differences were statistically significant (P < 0.05). The levels of prevalence of both microdontia and dilacerations were 4.00% (174/4,347) and 2.16% (94/4,347). The prevalence of cusp deformity, odontoma, and fused teeth were relatively low at 0.74% (32/4,347), 0.51% (22/4,347), and 0.39% (17/4,347), respectively. CONCLUSION The prevalence of teeth number and morphology abnormalities in children's permanent teeth at the mixed dentition stage is apparently high. Tooth agenesis and supernumerary teeth are the most frequent. Panoramic radiograph is an efficient method for the early diagnosis of teeth number and morphology abnormalities. This method can assist pediatric dentists to formulate treatment plans for children at the appropriate time.

Abstract
AIM To examine the prevalence of different types of dental anomalies in children with nonsyndromic cleft lip, unilateral cleft lip-palate, and bilateral cleft lip-palate. MATERIALS AND METHODS A sample of 90 patients (aged 4-20 years) affected by isolated cleft lip, unilateral and bilateral cleft lip and palate was examined. Cleft patients were classified into one of three groups according to cleft type: (1) Unilateral Cleft Lip-Palate, (2) Bilateral Cleft Lip-Palate, and (3) Cleft Lip. Intraoral exams, panoramic radiographs and dental casts, were used to analyse the prevalence of the various dental anomalies included in this study. RESULTS There were no statistically significant differences between patients with cleft lip, unilateral cleft lip and palate and bilateral cleft lip and palate. The congenital absence of the cleft-side lateral incisor was observed in 40% of the sample, and a total of 30% patients showed supernumerary teeth at the incisors region. Second premolar agenesis was found in 4.4% of patients, whereas in 18.9% of the sample there was an ectopic dental eruption. Lateral or central incisors rotation was noted in 31.1% of the sample, while shape anomaly, lateral incisor microdontia, and enamel hypoplasia were detected respectively in 25.6%, 5.6% and 18.9% of cleft patients. CONCLUSION High prevalence of different dental anomalies in children with cleft lip and unilateral and bilateral cleft lip and palate has been confirmed. This study, in particular, shows the presence of ectopic and rotated teeth in the cleft area.

Abstract
The data of clinical examination, diagnostic models and panoramic x-rays investigation of the 332 patients at the age from 6 to 18 years with adentia were analysed. The congenital absence of more than 6 teeth was defined as oligodontia. The purpose of the study was to evaluate the prevalence of missing teeth patterns and other dental abnormalities such as microdontia, persistent deciduous teeth, ankylosis, taurodontism, impaction and transposition in children and adolescents with isolated and syndromic oligodontia to optimize the diagnostic and orthodontic treatment plan. The total number of 332 patients were devided into three groups: 1-132 patients with hypodontia, 2-119 subjects with isolated oligodontia and 3 - 81 with syndromic oligodontia. The subgroup comprised of 45 children with ectodermal dysplasia (ED) syndromes and oligodontia 1,5-6 years at baseline examination was selected from the patients of group 3. The main type of inheritance was X-linked recessive and the most spread syndrome was hypohidrotic ectodermal dysplasia or Christ-Siemens-Touraine syndrome. The female patients were twice more than males in hypodontia and isolated oligodontia groups, but in group of 3 syndromic patients the rate of males to females was 1,56:1. The most stable to agenesis teeth were the upper central deciduous and permanent incisors. In group 2 the most often absent teeth were upper second premolars and in group 3-the upper lateral incisors. In syndromic patients with temporary dentition the upper lateral incisors and all lower incisors were always absent. It was concluded that the absence of teeth at the age of 1,5 years, male gender and absense of more than 14 teeth in the temporary dentition and 20 teeth in the permanent dentition were the signs of syndromic oligidontia. It is necessary for such patients to be examined besides dentists and pediatrician by other medical specialist such as dermatologist and geneticist.

Abstract
BACKGROUND Teeth changes after chemotherapy are of clinical importance, but no morphological studies were conducted on microscopic level. AIM To assess morphological changes in teeth developing under chemotherapy. MATERIALS AND METHODS Twenty-nine adolescents aged 13-16 years that received chemotherapy at the age of 2-13 were included in the study. Teeth morphology was evaluated by means of clinical and radiological data as well as microscopy of extracted teeth (n=13). Thirty healthy children aged 13-16 and 8 teeth extracted for orthodontic reasons served as a control. RESULTS Chemotherapy has arresting impact on teeth development confirmed by aplasia of germs when influenced on stages I-II (p=0.0001), preliminary apexogenesis resulting in shortened roots in teeth at the later stages of growth and development (p=0.01). Enamel and dentine defects usually located in cervical area are also a specific feature, while caries incidence was not higher when compared to control group. CONCLUSION Children receiving chemotherapy have high risk of secondary teeth loss because of germs aplasia and extraction of severely decayed teeth. Early diagnostics helps to prevent secondary deformations of dental arches by prompt prosthetic rehabilitation. Root morphology changes should be considered by root canal treatment.

Abstract
BACKGROUND The study of dental anomalies is important because it generates information that is important for both the anthropological and clinical management of patients. The objective of this study is to determine the prevalence and pattern of presentation of dental hard-tissue developmental anomalies in the mix dentition of children residing in Ile-Ife, a suburban region of Nigeria. METHODS Information on age, sex and socioeconomic status was collected from 1,036 children aged four months to 12 years through a household survey. Clinical examination was conducted to assess the presence of dental anomalies. Associations between age, sex, socioeconomic status, prevalence, and pattern of presentation of the developmental hard-tissue dental anomalies were determined. RESULT Two hundred and seventy six (26.6%) children had dental anomalies. Of these, 23.8% had one anomaly, 2.5% had two anomalies, and 0.3% had more than two anomalies. Of the children with anomalies, 49.3%were male, 50.7%were female, and 47.8%, 28.6% and 23.6% were children from low, middle and high socioeconomic classes, respectively. More anomalies were seen in permanent than primary dentition. Anomalies of tooth structure were most prevalent (16.1%); anomalies which affect tooth number were least prevalent (1.3%). Dens evaginatus, peg-shaped lateral, macrodontia, and talon cusp were more prevalent in the permanent dentition, and dens evaginatus peg-shaped lateral and macrodontia were more prevalent in the maxilla. There were significantly more macrodontia anomalies in males and in children of high socioeconomic status. CONCLUSION This large survey of dental hard-tissue anomalies found in the primary dentition and mixed dentition of children in Nigeria provides anthropological and clinical data that may aid the detection and management of dental problems of children in Nigeria.

Abstract
Partial secondary adentia together with caries and parodont diseases is among the most widespread diseases of dentofacial system, correlated, in addition, to the number of lost teeth, with the age. Result in speech and chewing functions' disorders, change of face shape, esthetic and psychosocial inferiority, pathologies of digestive and other systems, formation of the chronic infection areas, changes of reactivity etc,. Improvement of the methods of prevention and treatment of the above diseases is one of the most significant problems in the dentistry. Effectiveness of dental assistance organization and planning is based on the epidemiological studies. In Georgia, epidemiological studies were conducted in the populations of various age groups in previous years though, according to our data, no studies of dentition defects and deformations were conducted in the recent decades. Goal of our research was study of prevalence and severity of dentition defects and deformations, regarding sizes of existing defects, their localization, causes and types of deformation in different age groups, for development of specialized dentistry assistance plans and prevention programs. We have studied 147 patients of ages between 15 and 40 years. We have developed special questionnaire. Researches showed that in the studied age group (15-40), 62% (96 patients), i.e. more than half of studied 147 patients had secondary adentia. Most of them had the defects in the buccal teeth area. 112 of studied 147 patients required orthopedic treatment but only 18 (16%) of them have visited the clinic for this purpose while 94 (83.9%) of them were unaware about need of prothetic assistance. Regarding significance of the mentioned problem, the obtained results show the need of timely orthopedic intervention for the purpose of prevention of further complications. As a result, a specialized dental assistance plan and prevention measures' program has been developed to prevent further complications.

Abstract
PURPOSE The purpose of this study was to evaluate the prevalence of various congenital dental anomalies in the permanent dentition of Turkish children with Down syndrome. METHODS The sample consisted of 216 diagnostic records of children diagnosed with Down syndrome. All subjects had a clinical examination as well as radiographs and photographs taken. Anomalies in the permanent dentition were documented. RESULTS There was a high incidence of dental anomalies, the most frequent being taurodontism (81 percent), rotation (28 percent), hypodontia (26 percent), tooth impaction (18 percent), ectopic eruption (14 percent), microdontia (13 percent), and hyperdontia (9 percent). Differences in prevalence of congenitally missing teeth, structural anomalies, and positional anomalies reached a statistically significant level regarding gender (P<.05). CONCLUSION Turkish children with Down syndrome presented a high incidence of anomalies affecting the permanent dentition, and, in most cases, individuals presented with more than one anomaly.

Abstract
Natal teeth erupt in utero, whereas neonatal teeth present during the first month of life. The lower central incisors are the most frequently affected teeth. The etiology is unknown, and the choice of treatment depends on several factors. The purpose of this paper is to review 23 cases of children with natal or neonatal teeth who attended a dental care program in a university maternal and infant oral health clinic. There was no gender predilection. Most were natal teeth (83 percent) and presented a mild degree of mobility (64 percent). Only two patients had breast-feeding difficulties (nine percent). Tooth maintenance was the most common treatment of choice (64 percent), and only two patients presented Riga-Fede disease (nine percent).

Abstract
AIM Enamel pearls are a tooth anomaly that can act as contributing factors in the development of periodontal disease. Studies that have addressed the prevalence of enamel pearls in populations were scarce. The purpose of this study was to evaluate the prevalence of enamel pearls in the permanent dentition of Turkish dental patients by means of panoramic radiographs. PATIENTS AND METHODS Panoramic radiographs of 6912 patients were examined for the presence of enamel pearls. All data (age, sex and systemic disease or syndrome) were obtained from the patient files and analyzed for enamel pearls. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. RESULTS Enamel pearls were detected in 5.1% of subjects and 0.85% of the teeth examined. Prevalence of enamel pearls was higher in males (6.58%) compared to females (3.96%). The mandibular first was the most commonly affected tooth. Enamel pearls were significantly more common in the mandibula compared with the maxilla (81.2% cf 18.8% respectively, p = 0.000). No statistically significant differences were found between the right-side and left-side occurrences. CONCLUSIONS With the prevalence of 5.1% among the Turkish population, every possible effort should be made for locating of this anomaly especially in molars because it might be useful for prevention periodontal problems.

Abstract
OBJECTIVE To investigate the prevalence and characteristics of dental anomalies (DAs); missing teeth (MT), dens-evaginatus (D-E), dens-invaginatus, dilaceration,fusion, gemination, macrodontia, microdontia (Micro), supernumerary teeth (SNT), and taurodontism, in permanent teeth among subjects with non-syndromic oral cleft. MATERIAL AND METHOD This cross-sectional study was designed to assess DAs from diagnostic records; comprising panoramic radiograph, intraoral photographs, dental casts, and orthodontic clinic charts of 280 Northeastern Thai subjects, mean age 10.3 +/- 3.2 years. Chi-square test was used to compare DA prevalences among cleft phenotypes and genders. RESULTS There were one or more teeth with DAs in 89.6% of the study population. Highest prevalence was MT (60.4%) followed by Micro (41.4%), dilaceration (6.4%), SNT (6.1%) , and 0.4% in D-E, fusion, gemination, and taurodontism. The most prevalent MT was found in 70.7% of subjects in bilateral cleft lip and palate group. CONCLUSION The two predominant DAs were MT and Micro, higher prevalences being found with the more severe cleft conditions. The most affected teeth were cleft-site lateral incisors. There were no differences in distribution of DA in male and female.

Abstract
AIM This study aimed to investigate the prevalence of dental anomalies and study the association of these anomalies with different types of malocclusion in a random sample of Saudi orthodontic patients. MATERIALS AND METHODS Six hundred and two randomly selected pretreatment records including orthopantomographs (OPG), and study models were evaluated. The molar relationship was determined using pretreatment study models, and OPG were examined to investigate the prevalence of dental anomalies among the sample. RESULTS The most common types of the investigated anomalies were: impaction followed by hypodontia, microdontia, macrodontia, ectopic eruption and supernumerary. No statistical significant correlations were observed between sex and dental anomalies. Dental anomalies were more commonly found in class I followed by asymmetric molar relation, then class II and finally class III molar relation. No malocclusion group had a statistically significant relation with any individual dental anomaly. CONCLUSION The prevalence of dental anomalies among Saudi orthodontic patients was higher than the general population. CLINICAL SIGNIFICANCE Although, orthodontic patients have been reported to have high rates of dental anomalies, orthodontists often fail to consider this. If not detected, dental anomalies can complicate dental and orthodontic treatment; therefore, their presence should be carefully investigated during orthodontic diagnosis and considered during treatment planning.

Abstract
OBJECTIVE To determine the prevalence of permanent tooth anomalies in patients attending the graduate orthodontic clinic at the State University of New York at Buffalo. MATERIALS AND METHODS Charts of 496 subjects (310 females and 186 males) met the inclusion criteria for this study. The mean ages were 16 years and 3 months for the combined gender sample that received orthodontic treatment in the graduate orthodontic clinic between 2007 and 2010. Full pretreatment records (intraoral photographs, digital study models, lateral cephalograms and panoramic radiographs) were used for the assessment. Charts were examined for these anomalies: agenesis, supernumerary, impaction and delayed tooth eruption. Subjects were categorized by gender and ethnicity. The percentages of the anomalies were assessed according to type of malocclusion, gender, race, location, tooth class and region in the dental arches. RESULTS Sixty-four subjects (12.9%) had at least one occurrence of delayed eruption and impaction (DEI), followed by 47 subjects (9.5%) who had at least one occurrence of agenesis, and seven (1.4%) had a supernumerary condition. Approximately 80% of the subjects had no dental anomalies. The presence of more than one anomaly was observed in 61 subjects. Twelve subjects (2.4%) had both agenesis and DEI. Agenesis tended to be more common in class II malocclusions (p=0.012). CONCLUSION The prevalence of permanent tooth anomalies was (20.4%). The percentage occurrence of DEI was the highest (12.9%) followed by dental agenesis (9.5%) and supernumerary teeth (1.4%) in the orthodontic patients at the State University of New York at Buffalo.

Abstract
The aim of this study was to establish teeth number anomalies in relation to gender, tooth type, location, distribution pattern and the association between frequently missing teeth among a group of dental patients in Turkey. A total of 378 non-syndromic patients (240 females and 138 males) with an age range of 7-45 (x +/- SD = 22.07 +/- 3.6) having evidence of absent or excess teeth were evaluated in the study. Pearson Chi-square, Fisher's exact, McNemar and Kappa coefficients were used for statistical analysis. 237 patients had a total of 546 congenitally missing teeth and 141 had 185 excess teeth. Congenitally missing teeth were more commonly seen rather than the presence of supernumerary teeth. Difference was determined in the frequent locations of congenital missing and supernumerary teeth. The most frequent missing tooth type was found to be the mandibular second premolar (26.6%), while the majority of supernumerary teeth were located in the anterior region of the maxillary arch (37.9%). Both teeth number anomalies were more commonly seen among females. In hypodontia cases the occurrence of symmetrical agenesis of laterals and second premolars in maxilla; centrals and second premolars in mandible was notable. Agenesis of mandibular centrals was found to be associated with maxillary lateral agenesis in males. Also higher prevalence of molar teeth agenesis was determined in the occurrence of at least 4 teeth agenesis. These findings will serve as information about the contemporary demographic pattern of teeth number anomalies among non-syndromic Turkish dental patients and can provide evidence that agenesis of some teeth symmetrically or together are the products of the same genetic mechanisms.

Abstract
PURPOSE The fusion of primary teeth may be associated with the absence of 1 of the 2 permanent successors. Moreover, even if both successors erupt, developmental disturbances such as microdontia or delayed tooth formation may occur. The purpose of this study was to elucidate the effects of different combinations of fused primary teeth on the eruption of permanent successors. METHODS One hundred ninety-seven children with 247 fused primary teeth were examined. Combinations of primary teeth involved in the fusion were identified, and the effects of these different combinations on the presence, morphology, and eruption of the permanent successors were determined. RESULTS Three types of fusion in the primary teeth were identified: (1) between the maxillary central and lateral incisors (UCI/LI); (2) between the mandibular central and lateral incisors (LCI/LI); and (3) between the mandibular lateral incisor and canine (LLI/C). The results revealed an absence of the successional lateral incisor in 65% of UCI/LI cases and 74% of LLI/C cases, whereas only 16% of LCI/LI cases resulted in a missing successor. CONCLUSIONS Fused primary teeth are highly correlated with the absence of permanent teeth, and the prevalence depends on the combination of fused primary teeth.

Abstract
PURPOSE We had for objective to assess odontogenic disorders associated to a congenital piriform aperture stenosis and to study their various presentations. METHODS Twelve patients presenting with a congenital piriform aperture stenosis, 1 week to 3 months of age, were retrospectively included from 1998 to 2008. All patients underwent an initial CT scan to evaluate the temporary dental germs. RESULTS Deciduous dental germs were abnormal in 75% of the cases. Thirty-three percent had a single median maxillary central incisor. DISCUSSION The concept of solitary median maxillary central incisor syndrome makes for a more pathophysiological approach of this type of disease, with various clinical presentations, corresponding to various levels of severity of a same pathological process.

Abstract
OBJECTIVE To analyze the prevalence, distribution, clinical features, and relationship with dental anomalies of maxillary canine impaction. MATERIALS AND METHODS The complete pretreatment records of 1674 orthodontic patients were examined. Subjects with maxillary impacted canines were divided into two study groups: a palatally displaced canine (PDC) group (114 patients) and a buccally displaced canine (BDC) group (37 patients). These were compared to a control group of 151 patients who were randomly selected from the initial sample without maxillary canine impaction. The significance of associations between canine impaction and dental and clinical features and anomalies was examined with the chi-square test. RESULTS PDC patients presented with normal overjet and facial profile and a lower degree of dental arch crowding in comparison to the control patients. PDC patients showed a higher prevalence of impaction of other teeth, dental aplasia, transposition, and peg-shaped maxillary lateral incisors (odds ratios 3.3, 2.6, 8.3, and 5.8, respectively). CONCLUSION PDC was frequently the only orthodontic problem of patients. BDC group patients did not present with notable differences in clinical and dental features or dental anomalies compared to control subjects.

Abstract
PURPOSE The purpose of this study was to explore the association of mandibular incisor agenesis with other dental anomalies in Japanese orthodontic patients. METHODS A total of 52 subjects with 1 or 2 congenitally missing permanent mandibular lateral incisors (group A) were selected and divided into group 1a (26 subjects with 1 lateral incisor missing) and group 2a (26 subjects with 2 lateral incisors missing). Fifty two sex-matched subjects without agenesis of the mandibular lateral incisor served as controls (group C). Radiographs, study models, and medical and dental records were used to identify anomalies of teeth. RESULTS The prevalence rate of agenesis of teeth other than the mandibular lateral incisors and third molars was significantly increased in group A. Agenesis of the maxillary second premolars was significantly increased in groups 2a and A. Significantly increased prevalence rates of symmetrical tooth agenesis, with third molars excluded, and third molar agenesis were observed in group 1a and A. CONCLUSIONS Japanese subjects with agenesis of 1 or 2 permanent mandibular lateral incisors have significantly increased prevalence rates of other permanent tooth agenesis and symmetrical tooth agenesis.

Abstract
The objective of this study was to determine the prevalence of taurodontism in primary mandibular first molars in ethnic Indian children using periapical radiographs. Periapical radiographs of 274 children obtained from December 2008 to August 2010 were retrospectively screened and examined. Radiographs of 196 patients (99 boys and 97 girls; ages 2.5-10.5) with bilateral primary mandibular first molars were randomly selected and evaluated. The gender, symmetry, and frequencies of occurrence of taurodont primary mandibular first molars were compared and the obtained data were statistically analyzed using the x2 test. Eight (4.08%) taurodont primary mandibular first molars were found with a bilateral incidence of a symmetrical distribution of 38% (3/8). The prevalence of taurodontism in primary mandibular first molars did not differ significantly between right and left sides or with gender (P ≥ 0.05). The results of the present study indicate that approximately 4% of Indian children had taurodontism in primary mandibular first molars. Clinicians should be aware of the prevalence of this anatomic variant in primary mandibular first molars among the Indian population for early identification of taurodonts and for rendering the best care during dental treatment.

Abstract
AIM The findings of a clinical-radiological review of 467 children attending the Oral Diagnosis Clinic of the Facultad de Odontología, UNAM, Mexico, are presented. METHODS All patients were clinically reviewed, clinical history was taken, and an orthopantomogram obtained by last year dentistry students. Patients and radiographs were then reviewed by the panel and all alterations in teeth, soft tissues and bone were recorded. RESULTS Clinical and/or radiographic alterations were found in 132 (28.26%) children. The main alterations were developmental (75%) and inflammatory/infectious and traumatic (6.06% each). The most common entities were: supernumeraries (30.77%); hypodontia (29.7%); osteosclerotic lesions and microdontia (4.4% each). CONCLUSION The data on the frequency of alterations in the pediatric population attending at our institution reinforce the importance of this kind of study in efforts to improve the quality of stomatologic services in the pediatric population.

Abstract
PURPOSE The purpose of this study was to compare the prevalence of dental anomalies in the primary and permanent dentition of patients with unilateral (UCLP) and bilateral (BCLP) cleft lip with or without palate. METHODS One hundred two complete clinical records were randomly selected for review from a university-based cleft palate clinic. Only nonsyndromic UCLP and BCLP cases were further selected for analysis of dental anomalies. The prevalence of 9 dental categories, including anomalies in number, crown structure, position, and maxillary-mandibular relationship, was assessed and compared between UCLP and BCLP cases using Fisher's exact test. RESULTS Of the 102 charts evaluated, there were 67 cases of UCLP and 29 cases of BCLP for a total of 96 cases. There was a high prevalence of dental anomalies in primary and permanent teeth; 93% of UCLP cases and 96% of BCLP cases presented with at least 1 dental anomaly. Significant differences ( P <.05) were only found in the prevalence of anodontia of a single tooth (UCLP=39%, BCLP=14%), multiple anodontia (UCLP=22%, BCLP=54%), and anterior malocclusion (UCLP=15%, BCLP=41%). CONCLUSIONS There is a high prevalence of dental anomalies associated with orofacial clefts regardless of whether they are unilateral or bilateral cleft lip with or without palate.

Abstract
The aim of this study is to investigate the prevalence of dental anomalies in a group of individuals with different types of clefts attending the reference service in orthodontics for the care of patients with clefts in Paraiba state, northeastern Brazil. This was a cross-sectional, observational study. Two previously trained examiners (kappa = 0.89) performed the clinical examination of 76 patients with post and incisive transforamen unilateral or bilateral clefts, of both sexes, aged 4 to 32 years, and the analysis of periapical and panoramic radiographs from archived records of these patients. Only the upper front teeth were evaluated. Data were processed by descriptive statistics and subjected to statistical Chi-square test considered significant at 5%. Among the patients evaluated, males (57.9%) and left unilateral transforamen clefts (40.8%) were prevalent. Of the total 76 patients examined, 56 (73.68%) had at least one dental anomaly, the most frequent being agenesis (31.6%) and conical teeth (28.9%). The presence of anomalies differed significantly between the cleft and the contralateral sides (p<0.00001). The diagnosis and treatment of patients with clefts should therefore receive more attention. It is suggested that clinical and radiographic examination be performed together with careful planning and implementation of specialist services in an effort to provide early and adequate detection and treatment.
