Prevalence and distribution of dental anomalies in a subpopulation of the west region of Turkey

The aim of this study was investigate the prevalence and distribution of dental anomalies among 10- to 25-year-old patients by using panoramic radiographs. a total of 3600 patients (2200 male,1400 female,mean age: 19.2±6.3) panoramic radiographs were evaluated. dental anomalies were divided into five types: position anomalies,number anomalies,size anomalies,shape anomalies and structure anomalies. all permanent teeth were investigated except third molar teeth. the percentages of these anomalies were evaluated and compared between gender. developmental dental anomalies prevalance in turkish population was 6.8%. the prevalence of dental anomalies females were higher than in males (female: 3.9%,male: 2.9%). the most frequently observed anomaly was hypodontia (4.3%) followed by peg-shaped teeth (0.5%). amelogenesis imperfecta (0.03%) was the rarest anomaly in the total group. the most common type of dental anomalies were number anomalies. distribution of dilaceration statistically significantly differed between genders (p=0.01),whereas distribution of others did not. the types and the frequency of dental anomalies have varied in populations. for this reason,identification of the types of dental anomalies and their prevalence by age,gender and jaw can help clinicians perform a better diagnosis of dental anomalies expecially for esthetic and orthodontic treatment planning.
