“…Numerous studies have reported that tooth agenesis is more common in the mandible than in the maxilla (6,7,16,18), and these results were in agreement with our results. However, other studies have shown that the tooth agenesis was dominantly in the maxilla (8,15,17).…”

“…In this research, agenesis of the second lower premolar was most common, followed by the upper lateral incisor, upper second premolars and lower central incisors. Most other studies confirmed the same (3,5,6,8,(16)(17)(18), in contrast to some studies, where the upper lateral incisor was the most commonly affected tooth (11). Generally, agenesis of certain teeth was more prevalent in female subjects (Figure 3), which is related to the overall prevalence of tooth agenesis in our sample.…”

“…Bilateral tooth agenesis was more frequent than unilateral, where bilateral was more often present in female subjects, and unilateral in male subjects, but there were no statistically significant differences. However, the results of several studies have shown that the unilateral occurrence of tooth agenesis was more frequent than bilateral (8,16,18), but these differences were small and were not statistically significant.…”

“…The reported prevalence of hypodontia, excluding the third molar, varies from 4.30% to 9.0% in the population of orthodontic patients (5,7,11,16,17) and from 1.11% to 11.01% in the population of other dental patients (3,4,6,8,12,18). The wide range of prevalence of hypodontia may be attributed to differences in sampling methods and sample size, as well as ethnic and racial differences.…”

Objective. The aim of this study was to assess the prevalence of hypodontia and hyperdontia among a group of orthodontic patients.Materials and Methods. This cross sectional study was conducted using radiographs of 4256 patients (2032 males and 2224 females) who attended the Department of Orthodontics, School of Dental Medicine, University of Sarajevo. Radiographs were examined for the prevalence of hypodontia and hyperdontia in permanent dentition. Hypodontia was recorded when a tooth was absent on the panoramic radiograph and hyperdontia was recorded as an increased number of teeth above that described by normal dental formula. All data were analyzed using descriptive statistics including frequency and percentage, and differences between groups were tested using the χ2 test, or Fisher exact test.Results. In the sample of orthodontic patients, 4.08% subjects had a least one dental anomaly, hypodontia or hyperdontia. The observed prevalence of hypodontia was in 3.42% subjects, and it was more prevalent in females than in male subjects. The observed prevalence of hyperdontia was in 0.65% subjects and hyperdontia was more common in males than female subjects.Conclusions – By early diagnosis of a reduced or increased number of teeth, various modes of therapy with a multidisciplinary approach may be performed to correct the aesthetic and functional problems caused by hypodontia or hyperdontia.

“…In the present study the prevalence of supernumerary teeth in Mongoloid children of Manipur in North East India has been found to be 0.9%. Interestingly this is similar to the prevalence reported in other parts of India which were 0.9% in study done by Mahabob et al and 0.7% in study done by Saha et al but lower as compared to 1.3% as reported by Sharma et al and 2.97% as reported by Soni et al [6][7][8][9] . The prevalence found in this study was found to be higher as compared to a study by Shilpa et al who reported a prevalence of 0.21% in primary dentition 10 .…”

Background: Teeth may vary in number, size, and shape. Supernumerary teeth are a developmental anomaly of the number which may involve both primary and permanent denti tions. Objectives:The objectives of the present study were to deter mine the prevalence of supernumerary teeth in the pediatric population of Manipur in North East India and to study the characteristics of supernumerary teeth. Study Design: Observational study. Materials and methods:The study was carried out in children from 3 to 14 years of age. Four thousand thirty-two children were examined over a period of 6 months who reported to the Department of Paediatric and Preventive Dentistry, Dental College, Manipur. Children with only supernumerary teeth were included whereas children with syndromes which are known to be predisposed to supernumerary teeth were excluded. The clinical and radiographical examination was done for diagnosis. Demographic details (age and sex) of children and characteristics of supernumerary teeth were noted. Results: Out of 4032 children examined, supernumerary teeth were detected in 36 children (0.9%). Males were affected more than females with a male:female ratio of 2.3:1. Maximum super numerary teeth were seen in mixed dentition (66.6%). About 86.1% of children had only one supernumerary tooth. 92.7% of supernumerary teeth were located in premaxilla. Conical shape was the most predominant (65.8%). 75.6% supernumerary teeth erupted while 24.3% were impacted. The majority were oriented straight (87.8%) with complete crown and root formation (80.4%). Conclusion:The prevalence of supernumerary teeth was found to be 0.9% with the most common location being the premaxilla. Maximum supernumerary teeth were erupted and had straight orientation.

An orthopantomographic study of prevalence of hypodontia and hyperdontia in permanent dentition in Vadodara, Gujarat

Abstract: There was a high prevalence of hypodontia and a low incidence of hyperdontia in the studied population. Prompt diagnosis of these anomalies can help plan treatment modalities at an early age to establish a functional and esthetic dentition.
