Abstract
Background: Unerupted or partially erupted teeth may be impacted, which means they are prevented from completely erupting into the normal functional position. The present study was conducted to evaluate third molar impaction status in different facial types and mandibular length.
Materials & Methods: 65 patients with third molar impaction of both genders were included. Parameters such as facial height, facial width, mandibular length, facial indexwas calculated as facial index= facial height ×100/facial width.
Results: Short mandibular length was seen in 45, normal in 12 and long mandibular length in 20 patients. The difference was significant (P< 0.05). Impaction was seen among 10 hypereuryprosopic males and 4 females, 22 Euryprosopic males and 16 females and 8 Mesoprosopic males and 5 females. The difference was significant (P< 0.05).
Conclusion: A significant association between mandibular length and mandibular third molar impaction was found.
