Relationship between third molar impaction & growth pattern: A radiographic study

Abstract

Objective: To investigate the relationship between mandibular third molar impaction & facial growth pattern.
Material &Methods:Records of two hundres & forty subjects were selected from students of Rama University,Mandhan,Kanpur. Their pretreatment OPG & Lateral cephalograms were analysed. Degree of impaction was assessed using Pell Gregory system. The patients were divided into the three facial growth patterns on the basis of MP-SN angle.
Results: The percentage wise distribution of third molar impaction in horizontal, average & vertical group was found to be 30.07%,33.83%,36.09% respectively. No statistically significant difference was found between the groups.
Conclusion: No significant association could be established between different facial growth pattern &third molar impaction.
