Clinical and orthopantomographic evaluation of mandibular third molar.

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, number, 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.
