3rd Molar variations via radiograph

Abstract

Objectives: To determine Morphological variations in Third Molars as seen on Panoramic Radiograph only, and determine a possible association of these variations with gender and different age groups divided into 5 groups from 18 years to 55 years, visiting Dental Department of Dow University of Health Sciences. Methodology:Retrospective Observational study based on OPG of patients visiting department of oral medicine and radiology at DOW University of health sciences, Karachi were selected. For purpose of our study OPG of 350 patients were selected. After considering the inclusion and exclusion criteria 240 radiographs of patients aged 18 years and older were included in this study. Age study samples were categorized into 5 age groups. Chi Square test was used to predict possible associations between 3 rd molars variations in morphology and Gender/Age groups.Results: Young Females had full bony mandibular impactions which was statistically significant X 2 (1): 2.32, P= 0.00. Increased variations in morphology such as multiple roots, long, fused and dilacerated roots were more prevalent in young individuals specially females. Conclusion: Variation in 3rd Molars are observed to vary among different age groups and Gender, further studies among different individuals from different ethnic backgrounds and culture will reveal new insights on these observed variations.
