Dentascan an excellent tool for assessment of variations in the management of periodontal defects.

Background: The purpose of the present study was to envisage the effectiveness of demineralized freeze-dried bone allograft (DFDBA) and bovine bone graft (BBG) for promoting defect fill in periodontal intrabony defects using dentascan.

Materials And Methods: A total of 13 subjects (15 intrabony defects) aged between 24 and 56 years affected by moderate to severe periodontitis were randomly divided into Control (CG) and Test groups (TG1 and TG2). In CG only debridement, TG1 debridement plus DFDBA, and TG2 debridement plus BBG were performed. The clinical parameters probing pocket depth (PPD), clinical attachment level (CAL) was used. The radiological analysis was done by dentascan, which is a single-slice spiral computed tomographic scanner. Six months after, regenerative treatment clinical measurements were recorded. The bone fill was assessed using Dentascan as previously mentioned.

Results: PPD reduction and CAL gain were significant in all the groups after 6 months whereas, on intergroup comparisons, insignificant finding was observed both at baseline and after 6 months. Coronoapical bone status decreased significantly in all groups, buccolingual measurements decreased significantly in TG1 and TG2, but no such trend was seen in CG. Significant reduction in mesiodistal bone status was noticed only in TG1 whereas insignificant on intergroup comparisons.

Conclusion: Dentascan-based analysis attested that DFDBA was superior to BBG.
