Clinical and orthopantomographic evaluation of mandibular third molar

Abstract

Objective: To evaluate sensitivity of orthopentograph (OPG) in assessing the number and morphology of roots of the mandibular third molar. Materials and Methods : The study population consisted of 100 ILTMs (impacted lower third molars) ranging from 18 to 42 years with equal sex distribution. All the teeth were subsequently extracted , collected and compared with OPG features for position, numb,er, morphology, and relation to mandibular canal. Conclusion: In conclusion, a large sample study is suggested with techniques like Clark′s and right angle technique which determines the three-dimensional orientation of the impacted teeth.
