Aim: This study aimed to assess the CBCT based radiographic correlation in bilateral impacted lower third molars so that, if correlated, data available for one side can aid in surgical planning for the other side or justifies the need for additional imaging.

Subjects & methods: DICOM files of 50 cases with bilateral impacted third molar were retrieved and both sides were compared according to four parameters.

Results: Results revealed statistically significant positive correlation between right and left sides regarding impaction angulation, number of roots, and crown caries. Weak correlation was found regarding inferior alveolar canal approximation.

Conclusion: Multicentric larger sample size study with detailed investigations is recommended.
