Abstract
Dental agenesis is one of the most common developmental anomalies in humans and it is frequently associated with several other oral abnormalities. The present case describes non-familial agenesis of permanent teeth in a twenty-one-year-old boy with no apparent systemic abnormalities. The treatment included a personalized and interdisciplinary approach involving endodontics, orthodontics, implant-supported restorations and prosthetic treatments. The treatment plan was thoroughly elaborated using photographic analysis, study models, orthopantomogram, CBCT and cephalograms. Virtual smile design, diagnostic waxing and mock-ups previsualized the treatment objectives. The edentulous spaces were reconstructed by inserting dental implants and monolithic zirconia implant-supported restorations. The final results showed a highly esthetic and functional rehabilitation. Periodic check-ups have shown that the stability of the result is well maintained and that the implant-supported restorations are an optimal solution for patients with multiple anodontia.

Abstract
Tooth agenesis, one of the most common developmental defects in humans, not only impairs oral function but can also lead to craniofacial deformities. Bibliometric analysis can reveal significant shifts in research and publishing trends within specific fields. This study aims to provide a comprehensive overview of the research hotspots in tooth agenesis and predict future trends through bibliometric analysis. We searched for English-language publications related to tooth agenesis from 2001 to 2021 on the Web of Science. The publications were limited to original and review articles, and bibliometric parameters such as publication year, country, institution, author, journal, citations, and keywords were extracted and analyzed using VOSviewer, Microsoft Excel 2010, and CiteSpace. A total of 2,287 papers were ultimately selected. The results show that the USA holds a leading position in the field of tooth agenesis research. A total of 9,803 authors participated in these studies, with Alexandre R Vieira from the USA being the most prolific and most cited author. This study indicates that multidisciplinary management has become the consensus first choice for treating dental agenesis. Gene mutations related to tooth agenesis continue to be a research hotspot attracting scholarly attention. Exploring the relationship between tooth agenesis and cancer may be a future research direction. These findings contribute to potential collaborations among experts in future research on the genetic causes of tooth agenesis and tumor development and to assist the scientific community by identifying research gaps in this field.

Abstract
Ectodermal dysplasia (ED) is an inherited disorder that affects the ectoderm of a developing embryo and impacts structures that originate from it. It typically presents as a triad of missing teeth (anodontia/hypodontia), sparse hair (atrichosis/hypotrichosis), and lack of sweat glands (hypohidrosis), often accompanied by nail dystrophy and palmoplantar hyperkeratosis. There are two main types of this condition: X-linked anhidrotic or hypohidrotic and hidrotic (autosomal type). The oral manifestation of ED may include anodontia or hypodontia, with or without cleft lip and palate. Tooth loss leads to a decrease in the height of the alveolar ridges, resulting in a reduction of the vertical dimension of the lower face, disappearance of the vermilion border, and prominent lips. As a result, the affected person's face may resemble that of an elderly individual. The current case report aims to illustrate the prosthodontic rehabilitation of 16-year-old male patient with ectodermal dysplasia and complete anodontia, visiting Dentistry Teaching Hospital, Kabul, Afghanistan. Fortunately, this patient was acceptably managed with the collaboration of several disciplines.

Abstract
Oligodontia demands multidisciplinary management due to its repercussions on dentofacial growth. To place implants to realize implant-borne fixed denture, preimplant surgery may be necessary if bone volumes are insufficient. Our aim was to assess bone increase following autogenic bone grafting and to discuss prosthetic options. Twenty patients followed for oligodontia, who underwent bone grafting, were treated from 2008 to 2019. Transversal and vertical bone levels were measured pre- and postoperatively to assess alveolar ridge augmentation. Mean horizontal grafting increase was 4.60 mm [standard deviation (SD) 0.79 mm], mean sinus lift increase was 9.95 mm (SD 2.35 mm). Mean implants placed per patient was 9, mean implants placed on grafted site was 5 per patient. Overall implant survival rate was 100%. All patients benefited from prosthetic procedures when it was planned to perform implant-borne fixed dentures. Within the framework of a complete treatment plan (involving paediatric dentistry, dentofacial orthopaedics, oral and maxillofacial surgery, and prosthodontics), autologous bone grafting combined or not with orthognathic surgery is fully adapted to patients with oligodontia. It allows reconstruction of favourable bone volumes for placement of implants to realize implant-borne fixed dentures, with high implant survival rates and great improvements to quality of life.

Abstract
OBJECTIVES To conduct a systematic review and meta-analysis to assess whether individuals with nonsyndromic orofacial clefts (OCs) display a higher frequency of dental anomalies (DAs) when compared with individuals without OCs. METHODS A literature search of indexed databases (PubMed, Cochrane, Web of Science, Embase, Scopus, and LILACS) was conducted without language restriction up to and including February 1, 2020. Cross-referencing was used to further identify articles. Several cleft teams across the United States and Europe were contacted to obtain unpublished data. The eligibility criteria were observational studies with original data that statistically compared individuals with OC without syndromes and those without OC on any type of DA in primary and/or permanent dentition. Random effects meta-analysis through the Mantel-Haenszel estimator was used to evaluate the association between OC and DA based on odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS The literature search generated 933 records, and 75 full-text articles were reviewed. Twenty-six studies encompassing 15,213 individuals met the inclusion criteria. The meta-analysis revealed statistically significant associations between OC and agenesis (OR, 14.2; 95% CI, 9.4 to 21.3), supernumerary teeth (OR, 5.7; 95% CI, 3.3 to 9.7), developmental enamel defects (OR, 5.6; 95% CI, 3.5 to 9.0), microdontia (OR, 14.8; 95% CI, 4.0 to 54.6), peg-shaped anterior teeth (OR, 12.2; 95% CI, 3.6 to 41.2), taurodontism (OR, 1.7; 95% CI, 1.0 to 2.7), tooth malposition and/or transposition (OR, 5.6; 95% CI, 2.8 to 11.5), tooth rotation (OR, 3.2; 95% CI, 1.3 to 8.2), and tooth impaction (OR, 3.6; 95% CI, 1.1 to 12.2). The OR estimates of the reviewed studies exhibited significant heterogeneity (P < 0.0001). No association was observed between OC and fusion and/or gemination. CONCLUSION Within the limitations of this study, the available evidence suggests that individuals with OCs are more likely to present with a range of DAs than their unaffected peers. KNOWLEDGE TRANSFER STATEMENT The findings of the current review suggest that individuals with orofacial clefts (OCs) are more likely to present with a range of dental anomalies than their unaffected peers. Understanding the association between OCs and dental anomalies is essential in guiding clinicians during treatment-planning procedures and is important in raising our awareness of the possible need for future dental treatment for patients with OCs.

Abstract
Purpose: Because of the high rate of agenesis and supernumerary teeth in orthodontic patients and the lack of studies in Lebanon that document the prevalence of those anomalies, the aim of this study was to determine the prevalence of hypodontia and supernumerary teeth in patients attending a pediatric dental office and examine the associated factors. Study design: This was a cross-sectional design study. The patients were clinically examined followed by panoramic radiograph. Two calibrated investigators have examined the radiographic films and diagnosed the dental anomalies. Tooth agenesis and supernumerary teeth were the outcome variables of the study. Tooth agenesis was diagnosed when there were no sign of crown calcification and no evidence or history of loss attributable to orthodontic treatment, caries, periodontal problems and dental trauma. Tooth agenesis and supernumerary teeth were the outcome variables of the study. Chi-Square tests and Fisher Exact tests were performed to assess the association between outcome variables, gender and presence of medical problem. Results: 334 participants (mean age 7.31±2.17 years) were included in the study. The presence of dental anomalies was not reported as a reason for dental visits. The rate of tooth agenesis was 8.7% in the whole sample, 9.9% among boys and 7.6% among girls with no difference (p=0.442). The rate of tooth agenesis was elevated in participant with medical problems (14.5%) compared to those with no medical problem (7.0%) (p=0.041). The rate of supernumerary teeth was 0.6% among boys and 0% among girls (p=0.485). Conclusion: Oral anomalies could be detected relatively at early age. It can help in a long-term and effective treatment planning. Early diagnosis and appropriate follow-up with panoramic radiograph is extremely important to avoid maxillofacial deformity and other complications.

Abstract
Purpose: Children in West Virginia have a high prevalence of missing permanent teeth when compared to children in the rest of the nation. The purpose of this study is to determine the prevalence of permanent tooth hypodontia/oligodontia/anodontia in West Virginia children and to compare the prevalence by sex.Methods: Five hundred panoramic radiographs of West Virginia children, ages 6-11 years, were examined for missing permanent tooth buds/permanent teeth. Data analyses included frequency determinations, Chi square analyses, and logistic regression.Results: Sixty children (12.0%, n=500) had at least one missing permanent tooth bud/permanent tooth. There were 15.5% of females and 8.8% of males who had at least one missing permanent tooth bud/permanent tooth. In adjusted logistic regression on at least one missing permanent tooth bud/permanent tooth, females had an adjusted odds ratio of 2.11 [95% Confidence Interval: 1.18, 3.75; p = .011] compared with males. Other variables in the analysis failed to reach significance.Conclusion: In this sample of West Virginia children, females were more likely to have at least one missing permanent tooth bud/permanent tooth compared to males. Early recognition and treatment planning for dental care is needed for children with hypodontia/oligodontia/anodontia.

Abstract
Hypohidrotic ectodermal dysplasia (HED) comprises a large group of inherited disorders of ectodermal structures, characterised by hypo- or anhidrosis, hypotrichosis and hypo- or oligo- or anodontia. We aimed to systematically assess the spectrum of prosthodontic approaches with regard to the patients' age and to provide clinical implications for practicing dentists. An electronic and manual search was conducted in four databases (Medline, LIVIVO, Cochrane Library, Web of Science Core Collection). Publications of multiple study designs written in English or German without data restrictions, reporting on prosthodontic treatment of patients diagnosed with HED and afflicted with oligo- or anodontia, were included. In total, 75 articles on 146 patients were analysed according to the patients' age. In children aged 2-17 years, removable full or partial (over)dentures represented standard treatment. In the mandible, implant-supported removable dentures on two interforaminal implants presented an alternative, already in young childhood. In cases with more than six teeth per jaw, also fixed (resin) bridges were used, frequently after orthodontic treatment. In adults, fixed or removable reconstructions with the help of up to eight implants per jaw, usually placed after bone augmentation procedures, were standard. Ten case reports/series with long-term follow-up illustrated the need for consistent maintenance including denture renewals. Prosthodontic rehabilitation should start in early childhood and needs to be revised in accordance with the patients' growth. Treatment should be carried out by a multidisciplinary team addressing variable demands in different age groups.

Abstract
Objectives The aim of this study was to evaluate the association between tooth agenesis and skeletal malocclusions in Brazilian non-syndromic orthodontic patients. Material and Methods Pretreatment orthodontic records of 348 patients of both genders and with various skeletal malocclusions were examined. Tooth agenesis was evaluated in panoramic radiographs. Angular measurements were taken from lateral cephalometric radiographs to classify the patient’s malocclusion as skeletal Class I, Class II and Class III. Subjects were divided into 2 groups, “with tooth agenesis” and “without tooth agenesis”. Chi-square or Fisher exact test was used to compare categorical data. ANOVA with Tukey’s post-test was used for means comparisons. An alpha of 5% was established. Results From 348 analysed patients, 28 presented tooth agenesis. There was no difference between genders (P = 0.27) nor mean age (P = 0.16). The most prevalent skeletal malocclusion was Class I (63.11%), followed by Class II (25.94%), and Class III (10.95%). The mean of congenitally missing teeth was 1.3 (SD 0.13). Thirteen subjects had premolar agenesis, 13 upper lateral incisor agenesis, 4 lower incisor agenesis and 2 molars agenesis. The group with tooth agenesis presented A point-nasion-B point (ANB) angle smaller (1.66 [SD 2.52]) than the group without tooth agenesis (2.86 [SD 2.49]) (P = 0.01). ANB angle had a negative correlation with the number of congenitally missing teeth (P = 0.039; r = -0.39). Conclusions Tooth agenesis is associated with a smaller A point-nasion-B point angle and is negatively correlated with the number of congenitally missing teeth.

Abstract
Little is known about environmental risk factors for hypodontia. The objective of this study was to investigate the association between hypodontia and common environmental risk factors, such as maternal smoking and alcohol and caffeine consumption during pregnancy. Eighty-nine hypodontia cases with 1 or more missing permanent lateral incisors and/or 1 or more missing premolars were enrolled in this clinic-based case-control study. Some 253 controls with no missing teeth were frequency matched to cases by age and sex. Hypodontia was diagnosed using panoramic radiographs. Sociodemographic data were collected from both the participants and their mothers, with maternal self-reported active and passive smoking, as well as alcohol and caffeine consumption during pregnancy, assessed by a questionnaire. Odds ratios (ORs) and their 95% confidence intervals (CIs) were calculated with logistic regression to assess the strength of association between risk factors and hypodontia. OR estimates were then adjusted for possible confounders, such as maternal age at delivery, sex and gestational age of the child, and household socioeconomic background. Significant associations were found between hypodontia and maternal cigarette use during pregnancy, as well as the number of cigarettes smoked per day. The consumption of 10 or more cigarettes per day during pregnancy was associated with greater odds of having a child with hypodontia (adjusted OR, 4.18; 95% CI, 1.48-11.80; P = 0.007). Observed associations between hypodontia, second-hand smoke, and alcohol and caffeine consumption were not statistically significant. Maternal smoking during pregnancy is associated with hypodontia. Larger samples and prospective observational study designs, however, are needed to investigate this association further.

Abstract
OBJECTIVES The objective was to test the hypothesis of no difference in implant treatment outcome after installation of implants with a scalloped implant-abutment connection compared to a flat implant-abutment connection. MATERIAL AND METHODS A MEDLINE (PubMed), Embase and Cochrane library search in combination with a hand-search of relevant journals was conducted. No language or year of publication restriction was applied. RESULTS The search provided 298 titles. Three studies fulfilled the inclusion criteria. The included studies were characterized by low or moderate risk of bias. Survival of suprastructures has never been compared within the same study. High implant survival rate was reported in all the included studies. Significantly more peri-implant marginal bone loss, higher probing depth score, bleeding score and gingival score was observed around implants with a scalloped implant-abutment connection. There were no significant differences between the two treatment modalities regarding professional or patient-reported outcome measures. Meta-analysis disclosed a mean difference of peri-implant marginal bone loss of 1.56 mm (confidence interval: 0.87 to 2.25), indicating significant more bone loss around implants with a scalloped implant-abutment connection. CONCLUSIONS A scalloped implant-abutment connection seems to be associated with higher peri-implant marginal bone loss compared to a flat implant-abutment connection. Therefore, the hypothesis of the present systematic review must be rejected. However, further long-term randomized controlled trials assessing implant treatment outcome with the two treatment modalities are needed before definite conclusions can be provided about the beneficial use of implants with a scalloped implant-abutment connection on preservation of the peri-implant marginal bone level.

Abstract
Implants have gained tremendous popularity as a treatment modality for replacement of missing teeth in adults. There is extensive research present on the use of implants in adults, but there is a dearth of data available on the same in adolescents. The treatment planning and execution of implant placement in adolescents is still in its infancy. This review article is an attempt to bring together available literature.

Abstract
OBJECTIVES To compare the efficacy and safety of three orthodontic treatment modalities for agenesis of maxillary lateral incisors: 1) closing the space with the reshaped canine substituting the lateral incisor, 2) opening the space with placement of a conventional fixed bridge, and 3) opening the space with placement of a single-unit implant and an implant-supported crown. SETTING Brazilian Cochrane Center and Universidade Federal de São Paulo, Brazil. MATERIAL AND METHODS The following databases were investigated: Cochrane Register of Controlled Trials (Edition 12, 2011), EMBASE (from 1974 to December 2011), MEDLINE (from 1965 to December 2011), LILACS (from 1966 to November 2011), and Odontology Brazilian Bibliography Database (from 1966 to November 2011). Conference abstracts, main Brazilian dissertations and theses databases, and reference lists were handsearched. This systematic review included randomized or quasi-randomized controlled trials (RCTs) including women aged 15 years or over and men aged 21 years or over who received one of the interventions stated above. Two observers independently evaluated all the studies regarding eligibility criteria and assessed the risk of bias of included studies. RESULTS No studies were included in the review as no RCTs were found. Most of the evidence comes from case reports and narrative reviews on case reports and from three studies with a single post-intervention evaluation and non-comparable control groups with high risk of bias. CONCLUSIONS There is no scientific evidence for any of the three most common types of treatment for agenesis of the maxillary lateral incisors. RCTs into this issue are still necessary.

Abstract
Hypophosphatasia is a congenital disease characterized by deficiency of serum and tissue non-specific alkaline phosphatase activity. The disease occurs due to mutations in the liver/bone/kidney alkaline phosphatase gene. Six clinical forms of hypophosphatasia are recognized. Systemic symptoms of the disease are respiratory complications, premature craniosynostosis, widespread demineralization and rachitic changes in the metaphases, stress fractures, chondrocalcinosis and osteoarthropathy. Characteristic dental symptoms include premature loss of deciduous teeth, premature exfoliation of fully rooted permanent teeth, severe dental caries and alveolar bone loss. This clinical report describes the prosthetic rehabilitation of a sixteen year old female patient with hypophosphatasia with partial anodontia and no occlusion. Patient was managed clinically by saving her remaining teeth, fabricating a maxillary overdenture and mandibular cast partial denture. This not only helped her functionally in biting and chewing food and achieving a good occlusion, but also restored her confidence and self image by improving the aesthetics.

Abstract
Solitary median maxillary central incisor (SMMCI) is a rare dental anomaly. It is estimated to occur in 1:50,000 live births. The SMMCI tooth differs from the normal central incisor in that the crown form is symmetric and it develops and erupts precisely in the midline of the maxillary dental arch in both primary and permanent dentitions. Presence of SMMCI with hemifacial microsomia (HFM) is a very rare clinical condition. We report a case of HFM in a male of Indian origin who presented with SMMCI in both primary and permanent dentitions. The association of HFM with SMMCI may be due to defective development of neural crest cells and/or lack of space in maxilla.

Abstract
Individuals affected by ectodermal dysplasia syndromes have abnormalities of the glands, tooth buds, hair follicles, and nail development. Oral finding in ectodermal dysplasia patient are significant and can include multiple abnormalities of the dentition such as anodontia, hy-podontia or malformed and widely spaced peg like teeth, loss of occlusal vertical dimension, protuberant lips and lack of normal alveolar ridge development. This clinical report describes a combined surgical, pedodontic, and prosthodontic approach for the treatment of a patient with hypohidrotic ectodermal dysplasia.

Abstract
Ectodermal dysplasias are a large group of rare genetic disorders characterized by impaired development of hair, teeth, and eccrine glands in humans, mice, and cattle. Here, we review the cloning, mutation analyses, and functional studies of the known causative genes for the X-chromosomal anhidrotic ectodermal dysplasia (ED1) in these species. Mutations in the ectodysplasin 1 (ED1) gene are responsible for X-linked anhidrotic ectodermal dysplasia. The ED1 gene encodes a signaling molecule of the tumor necrosis factor family that is involved in development of ectodermal appendages. The bovine disorder may serve as an animal model for human ED1.
