Abstract:
Objectives: The prevalence of dental anomalies in different populations as demonstrated in several studies. So far, little is known about developmental anomalies in Libyan population. This research was aimed to: investigate prevalence of dental anomalies among a selected adult Libyan sample using panoramic radiograph.
Materials and Methods: Retrospective study of digital panoramic radiographs of (412) Libyan adult patients of both sexes (males and females) was collected from different Clinics in Benghazi district in period of six months. The radiographs were studied on computer screen to find out the prevalence of developmental dental anomalies. Descriptive statistics and bivariate analysis by age and gender were conducted using SPSS software.
Results: A total of 412 panorama radiographs were used in the data analysis. The majority were females (no=273, 66%), aged between 18 and 70 years old. The most common type of dental anomalies was dilaceration (no=130,31.6%), followed by impaction of wisdom teeth (no=66, 16%) and impaction of other teeth (no=23, 5.6%). A few cases of other anomalies were reported. These included one case of odontome, ectopic eruption of lift upper 8 and mesodens. were also seen
Conclusions: Dilaceration and impaction were the most common types of developmental dental anomalies among study population, with rare cases of supernumerary teeth and odontome. Multiple anomalies are common in the present study, suggestion genetic origin. The study showed that the prevalence of dental anomalies increases with the age of participants.
