Sumario: | AIM/OBJECTIVE: The mandibular third molar is the most frequently impacted tooth with incidence varies from 9.5% to 68% in different populations. Hence, the aim was to study the prevalence and pattern of mandibular impacted third molar among Delhi-National Capital Region (NCR) population. MATERIALS AND METHODS: The study was conducted with data collected from registered hospitals and dental clinics of Delhi NCR region. The study represents a retrospective analysis of panoramic radiographs and intraoral periapical radiograph of patients at these centers from June 2014 to June 2016. RESULTS: Out of 960 patients with the third molar investigated, a total of 250 patients having impacted mandibular third molar (152 [60.8%] males and 98 [39.2%]) females between June 2014 and June 2016 were included in the study. The age ranged from 20 to 55 years, with a mean age of 27.6 years and the standard deviation was 5.8 years. The prevalence of impacted mandibular third molars for this study was 26.04%. CONCLUSION: This study demonstrated that males (60.8%) were more likely to present with impacted mandibular third molars than females (39.2%). The prevalence of third molar impactions was almost the same on both the left (45.8%) and right (54.2%) sides. This study also noted that mesioangular impactions (49.2%) were the most common type of impaction. The least common form of impactions was the transverse types (2%). The prevalence of impacted mandibular third molars for this study was 26.04%. |
