Boon to dentistry of CBCT use: A lingual mandibular bone defect – A radiographic incidental finding

Objective: Since many decades we are using conventional radiography as it is commonly used world-wide. Conventional radiographs lacks many important features which needs to be enhanced in terms of quality of equipment, radiographic techniques used, to interpret accurately and radiation exposure risk, so it is a need of the day to confirm the hidden lesion with accuracy. So recent we came across a radiographic incidental finding of lingual mandibular bone defect by using CBCT. Results: We incidentally found stafne's bone cyst below the IAN canal on left side of the jaw in mandible with the help of CBCT. Conclusion: We concluded according to our observation, we observed that CBCT is useful and will have potential value when introduced in routine day to day life examination imaging method in dentistry to confirm the unknown hidden lesions that are most common finding.
