Objective: However, low cell counts in some categories (e.g. rare root shapes) warranted cautious interpretation. Continuous variables were summarized by mean and range (age), owing to the small sample size. Material and Method: A quasi-experimental clinical study was performed on patients needing lower third molar extraction, with CBCT-proven dose relation between the roots and the inferior alveolar canal. The protocol required establishing the direction of root movement (vertical, vertico-mesial, vertico-distal, vertico-lingual, or vertico-buccal) to ensure safe extraction. Results: The research comprised 62 cases with an average age of 27 years. The majority of participants were women (59.7%), and the most frequent type of impaction was mesioangular (45.3%). The Pell and Gregory classifications were mainly category II (71.0%) and B(50%). The majority of cases had two roots (71.0%) and exhibited a convergent shape (37.9%). The majority of moderate-to-very difficult surgical cases involve males. The most common occurrences were apico-lingual root relationship to the canal (29.0%), mesial cusp sectioning (45.2%), and the direction of extraction was most commonly vertical (65.4%). Importantly, no nerve deficits after surgery were noted. Conclusion: The CBCT-guided approach for anticipating root movement direction in lower third molar surgery shows promise as an effective supplementary strategy to avoid IAN damage.
