ABSTRACT

Introduction: The most common impaction found in the oral cavity is of third molar. The current study was done to find out the prevalence and pattern of mandibular third molar impaction. Material and methods: A study was carried out in the outpatient department of dentistry (MM College of Dental Science and Research) of the patients visiting the department between the age group 17-45 years. The angulation and pattern of third molar impaction was diagnosed with the help of IOPA (Intra Oral Periapical Radiograph) and OPG (Orthopantomograph) records of each patient based on Winter’s Classification. Chi square test was used to find the association and p ≤ 0.05 was considered as statistically significant. Result: A total of 400 patients were included in the study with males (n=246) and females (n=154). Mesioangular impaction (n=210; 52.5%) was seen as the most common of all mandibular impactions. Vertical impaction (n=46; 11.5%) was observed the least. When the pattern of mandibular impaction was compared according to age group, it was found to be statistically significant as p<0.05. Conclusion: The results of the present study can be used for further future voluminous studies involving impacted third molars.
