Abstract
BACKGROUND Supernumerary teeth are one of the most common anomalies in the human dentition, found most frequently in the maxillary anterior region causing impaction or displacement of the adjacent permanent teeth. AIM The purpose of this retrospective study was to determine the prevalence and characteristics of supernumerary teeth in orthodontically treated patients. STUDY DESIGN Pre-treatment facial and intraoral photographs, study models, panoramic and periapical radiographs of 3,000 consecutively treated orthodontic patients (mean age 12.2 years) from the Department of Orthodontics Tel Aviv University, were examined to detect supernumerary teeth in both arches. They were recorded according to gender, age, number, location, position and morphology. RESULTS Thirty-six patients, 22 (61%) males and 14 (39%) females with 50 supernumerary teeth, of which 42 (84%) were found in the maxillary anterior region, and 8 (16%) in the mandible, presenting a prevalence of 1.2%. CONCLUSIONS A prevalence of 1.2% was found in our study. The most common supernumerary tooth is mesiodens located at the maxillary anterior region. The characteristics of supernumeraries were based on their morphology, location and position. The most frequent complications caused were rotations, displacement and arrested eruption of maxillary incisors.

Abstract
An extra tooth to the normal formula of teeth sequence in any region of dental arch is regarded as Supernumerary teeth (ST). The reasons are still not clearly known, one of them being dichotomy of tooth bud, but the more accepted reason is the hyperactivity theory. Supernumerary teeth are present more in permanent dentition than in primary dentition and can present as a single entity or multiple, unilaterally or bilaterally, impacted or erupted, in either or both the dental arches. This article discusses the supernumerary teeth in detail with a case discussion of a non-syndromic 24-year-old girl, with six ST (bicuspids) present in all the four quadrants. In the mandible, ST's showed a classical clustered flower like presentation. The interesting feature in the presented case was the sequential orthopantomographs taken at various ages of the patient that showed continuous development of STs in all four quadrants, thus pointing to the theory of hyperactive dental lamina or atavism. An electronic search was conceded in PubMed, Cochrane Library and google scholar databases, and articles dated between December 1932 and December 2012 were selected to review the occurrence patterns of supernumerary teeth in non-syndromic cases.

Abstract
Abstract
Aim
The occurrence of multiple supernumerary teeth is rare and often found in association with syndromes such as cleidocranial dysplasia, Gardner's syndrome or cleft lip and palate. Few examples of non-syndromal multiple supernumerary teeth have been reported. The aim of this multi-centre study was to investigate the prevalence of supernumerary premolar teeth in non-syndromic patients and to investigate the association between the presence of supernumerary premolar teeth and malocclusion type in a Turkish population.
Materials and methods
The clinical records and panoramic radiographs of 10,700 patients (referred to three different university hospitals) were retrospectively examined for the presence of supernumerary premolars. Age, gender, orthodontic malocclusion type, the number of supernumerary premolars (two or more), the distribution, location, position (vertical, horizontal, inverted, mesio-angular), surgical approach, and related complications (pain, cystic changes, root resorption, or eruption disturbance of adjacent teeth) were recorded.
Results
Forty-two cases (13 Class I, 17 Class II, 12 Class III) of multiple mandibular supernumerary premolars in patients without an associated syndrome were detected. A total of 97 (27 Class I, 41 Class II, 29 Class III) supernumerary premolar teeth were found, with a prevalence of 0.39%. No statistical difference was found related to gender, malocclusion type and supernumerary premolars (p > 0.05). The majority of the extra premolars were located in the mandible, which was statistically significant (p < 0.05).
Conclusion
The present study revealed that the prevalence of multiple supernumerary teeth was 0.39%. The most frequently impacted premolars were found in the mandible and more often associated with Class II malocclusions in the examined Turkish population.

Abstract
Supernumerary teeth (ST) are uncommon alterations of development that may appear in either of the dental arches and that are frequently associated with syndromes such as cleidocranial dysplasia and Gardner syndrome. Multiple ST in individuals with no other disease or syndrome are very rare. In view of this situation, correct diagnosis, treatment and evaluation of ST with the use of appropriate imaging techniques are highly important. This case report presents radiographic images of a nonsyndromic 12-year-old female patient who presented with 14 supernumerary teeth and was treated under general anesthesia, with the extraction of all ST in a single surgical intervention. During the postoperative period, the patient did not complain of pain nor did she present any signs or symptoms of infection. During late follow-up period, due to difficulty in traction of the maxillary right canine and mandibular left first premolar towards the dental arch, it was necessary to extract these teeth under local anesthesia. Radiographic examination 3 years after surgery revealed the absence of ST and of diseases related to the existence of these teeth.

Abstract
BACKGROUND Non-syndromic multiple supernumerary teeth (NSMST) is a condition with a very low prevalence and which is opportunely described in the literature by case reports or group of cases. This represents a problem when it comes to describing and discussing the characteristics of this disorder. MATERIALS AND METHODS A search was conducted in PubMed, Web of Knowledge, Science Direct, and Scopus databases to locate and identify cases and series of cases about articles on multiple supernumerary teeth not associated with syndromes that have been reported so far. The following data were recorded: age, gender, total number of supernumerary teeth, number of teeth in both the maxilla and mandible, respectively, and number of teeth in each dental series (incisor, canine-premolar, and molar). Bilaterality in dental series and its localization in either maxilla or mandible were also determined. RESULTS A total of 46 cases including patients of both genders with a mean age of 19 years (SD = 6.826) and a ratio of 2.14:1 were identified. A total of 393 supernumeraries were reported; 43.26% (n = 170) were located in the maxilla and 56.74% (n = 223) in the mandible. No significant differences were found between genders with respect to the total number, involvement of the dental series, or distribution of supernumerary teeth in each of the arches. CONCLUSION Although NSMST is a condition that has a higher incidence in the male gender, no differences have been found as to their number and localization in both genders. Bilaterality seems to be a common characteristic of this disorder.

Abstract
BACKGROUND The authors conducted a retrospective study to determine the prevalence of supernumerary premolars in sample of patients from Madrid, as well as the possible complications associated with the presence of such supernumerary premolars. METHODS The study included a data assessment of all patients seeking dental care at a hospital's department of oral surgery across four years. The authors studied data from patients who had supernumerary premolars. RESULTS The authors identified supernumerary premolars in the records of 43 patients (0.32 percent) of the total population studied. These patients had 73 hyperdontic premolars (65 mandibular premolars [89 percent] and eight maxillary premolars [11 percent]). CONCLUSIONS Supernumerary premolars usually are diagnosed as a coincidental radiographic finding without an associated pathology. However, the authors found a higher percentage of comorbidity than they initially expected. CLINICAL IMPLICATIONS Mechanical or obstructive pathology was associated with 2.7 percent of the premolars, and enlargement of the follicular sac of more than 3 millimeters was present in 26.0 percent of the sample.

Abstract
The presence of three or more supernumerary teeth in one patient is uncommon. Genetic as well as environmental causes have been suggested as possible aetiological factors in the pathogenesis of supernumerary teeth. This report describes the dental findings and management of multiple supernumerary premolars in two siblings. The number and locations of the supernumeraries in both cases were almost identical. The findings from these cases give further support to the important role of genetic factors in the aetiology of supernumerary teeth. Primary care dentists who treat children should be aware of the possibility of familial occurrence of supernumerary teeth.

Abstract
PURPOSE The purpose of this study was to estimate the frequency of and describe the clinical characteristics and complications of patients with nonsyndromic multiple mandibular supernumerary premolars. PATIENTS AND METHODS Among 110,500 patients seen between July 2003 and January 2007, 32 cases of multiple (2 or more) mandibular supernumerary premolars were found. Data including age, gender, number, distribution, and location of supernumerary premolars, extraction procedure, and related complications (such as cystic changes, root resorption, or adjacent teeth eruption disturbance) were collected. RESULTS Six of 32 patients were female; the male to female ratio was 4.3:1. Prevalence of non-syndromic multiple mandibular supernumerary premolars was 0.029%. Mean age was 17.8 years. Root resorption of an adjacent tooth was found in 1 patient. Eruption anomalies were found in 5 patients and included impaction of a permanent tooth, prolonged retention of a deciduous tooth, and displacement of an adjacent tooth. Supernumerary teeth locations were predominantly lingual except for 4 teeth. CONCLUSION Prevalence found in this study was lower compared with previous studies. However, the rate of related complications was higher, even though the mean age was relatively low. Surgical intervention should be considered to prevent unwanted sequelae for any signs of complication.

Abstract
OBJECTIVE This study aimed to survey the demographic profile of supernumerary teeth (ST) in Brazilian children and adolescents. METHODS A retrospective analysis was carried out of all nonsyndromic patients with ST attended at the Pediatric Oral Surgery Service of the Universidade Federal de Minas Gerais between 1995 and 2004. Diagnosis of ST was based on clinical and radiographic examination. Chi-squared test was used for statistical analysis. RESULTS This study included 460 ST found in 305 patients. Radiographic assessment (32.1%) was the main care-seeking reason and also the means through which most (97.6%) permanent ST were identified. Most cases were single (63.0%), conical (44.6%), and unerupted (76.8%) ST. Most teeth were fully developed (41.3%), normally orientated (78.9%), placed in a palatal/lingual-sagittal position (84.1%), adjacent to the crown of permanent teeth (50.2%) (P < 0.001). The most frequent clinical complication was permanent teeth displacement (36.0%). Treatment was surgical removal followed by orthodontics (61.6%). CONCLUSIONS The demographic profile of ST herein presented will be useful to provide additional epidemiological information. A wide range of factors should be considered when evaluating ST. In addition, it is essential to detect ST as early as possible to avoid complications and to assure successful management. Even after treatment, patients must be followed up.

Abstract
Supernumerary teeth are common in the general population and occur more frequently in-patients with family history of such teeth. Multiple supernumerary teeth are associated with cleidocranial dyplasia and Gardner syndrome. However it is rare to find multiple supernumeraries in individuals with no other associated disease or syndrome. We describe the occurrence of multiple supernumerary teeth in a family occurring as a non-syndromal trait. The autosomal dominant transmission of non-syndromal multiple supernumerary teeth is new.
