VARIATION IN IMPACTION TYPES OF MANDIBULAR THIRD MOLARS IN WESTERN CHHATTISGARH- A DESCRIPTIVE CROSS-SECTIONAL RETROSPECTIVE STUDY

Dr. Bhavana Khandve

Abstract :

Background: Impacted third molars are prevalent and may lead to varied complications in oral cavity. This descriptive cross–sectional study adopted retrospective examination of the presence of impacted lower third molars and its variations using digital panoramic radiographs (DPRs). Objectives: To detect in the DPRs and to categorize the type of impactions in lower third molars. Results: Most prevalent type of impaction (TOI) was Mesioangular (MA) Impaction (60.9%), followed by Vertical (V) Impaction (18%), Horizontal (H) Impaction (12.8%), Transverse (TV) Impaction (4.5 %) and Distoangular (DA) Impaction (2.3 %), respectively. The Inverted (IN) type of impaction was least prevalent type. Conclusion: The high prevalence of MA may be related to the anatomical normal inclination of the third molars. The low prevalence of DA observed in the study sample on the other hand might be attributable to gender and demographic factors.
