“…Associations were found between MULI and four other DA in the present study ( Table 2). The associations with IT (p=0.0007) coincide with previous reports [6,31], as does that with dental transposition (p=0.002) [32].…”

“…The prevalence rate of transposition was relatively high (2.38%) compared to other reports: 0.27% [34], 0.33% [35], and 0.81% [32]. However, the present data coincides with these previous studies in that the uni-lateral presentation is the most common, and that the maxillary arch is the most af-fected [34- -36].…”

“…As reported elsewhere [34], all transposition cases in the present sample involved the canine teeth. Several DA are reported to be associated with transposition [32,34,36]. The DA associated with transpo-sition (MULI, BSULI, IT) in the present re-sults suggest a genetic origin for this phe-nomenon.…”

Background: Data on dental anomaly prevalence is instrumental to diagnosis and treatment in different populations. A retrospective study was done to determine dental anomaly prevalence and associations in a group of orthodontic patients in a Mexican population. Methods: Number, shape, eruption and structural dental anomalies were assessed from the records of 670 subjects. Prevalence, distribution, and associations between the different anomalies were calculated. Chi-squared and Fisher’s exact tests (p<0.05) were used to identify significant differences by sex, and to establish associations among the studied anomalies. Results: Twenty-eight percent of the sample exhibited at least one dental anomaly. Statistical analysis identified no differences by gender. The most common anomaly was impacted teeth (13.58%), followed by microdontic upper lateral incisors (6.26%). These two anomalies also had the highest number of significant associations with other anomalies. Conclusions: The dental anomalies prevalence documented here differ from those reported in the literature for other populations in the world. Dental anomalies are normally associated with each other and occur in groups linked to ethnic origin. The present results indicate the presence of differing suites of anomalies between the studied Mexican population and other populations in the world. This variation highlights the need for further research on dental anomalies in Latin America to aid in their diagnosis and treatment.

The prevalence, pattern and clinical presentation of developmental dental hard-tissue anomalies in children with primary and mix dentition from Ile-Ife, Nigeria

BackgroundThe 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.MethodsInformation 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.ResultTwo 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.ConclusionThis 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.

Introduction: Dental anomalies have been widely examined, but no such studies have been conducted in Norway. The purpose of this study was to examine the prevalence of dental anomalies and investigate their possible association with gender and dental occlusion. Methods: Panoramic radiographs and study models of 500, 12-year-old school children (273 girls, 227 boys) were analyzed for the presence of dental anomalies including agenesis, taurodontism, pulp stones, microdontia, macrodontia, impaction, short roots, supernumerary teeth, ectopic eruption and transposition. The subjects were divided into three groups according to the Angle classification (Class Ι, n = 252. Class ΙΙ, n = 227. Class ΙΙΙ, n = 21). Percentages and chi-square test were used for evaluation of the data. Results: In this population 28.2% of the subjects showed at least one dental anomaly. Statistically significant associations were observed between agenesis and Angle Class II dental occlusion (P = 0.03), and between agenesis and gender (P = 0.004). Conclusions: Agenesis was a predominant dental anomaly in girls and was found twice as often in subjects with Class ΙΙ, than with Class Ι dental occlusion.
