ABSTRACT
Introduction: The most common type of impaction is observed in the mandibular third molars. Numerous symptoms and pathologies such as bone loss, pericoronitis can cause due to impacted third molar. So, the aim of the study was to assess the bone resorption adjacent to third molar and distal to second molar and also to evaluate age estimation by periodontal ligament visibility of third molar.
Methods and material: 200 OPG’s were included in study. Bone resorption is measured on the OPG with respect to third molar and second molar. We also evaluated age estimation by periodontal ligament visibility by Olse’s method.
Results: Vertical type of impaction was seen more followed by mesioangular, horizontal and distoangular. Bone loss with respect to third molar was found to be slightly more with respect to third molar as compared with second molar, but the results were statistically insignificant. Most of the males and female presented with stage 2 were more than 21 years of the age.
Conclusion: The most common type of impaction seen in the adults was vertical type followed by mesio-angular type of impaction. Bone resorption was seen with respect to second and third molars. Periodontal ligament visibility of lower third molar may become an important method in forensic age estimation.
Key words: third molar impaction, bone resorption, periodontal ligament
