Abstract
Context and Aim: Radiographs play an important role in periodontal diagnosis; however, one of the major limitations of the conventional radiological procedures is the presence of considerable overlapping of the overlying anatomical structures and lack of a clear three-dimensional information. Surgical exposure, although being able to evaluate the type and depth of the defect during surgery, provides very little time to the surgeon to plan for the type of procedure required for periodontal regeneration based on the information obtained during surgery. Recently, cone beam computed tomography (CBCT) has emerged as a lower cost alternative to the computed tomography (CT) with high-quality images and lower radiation exposure to the patients, though, in vivo studies, in this regard, are still scarce. The aim of the present study was to assess the efficacy of CBCT in the detection of periodontal bone defects in patients with advanced periodontal disease indicated for periodontal surgeries.
Materials and Methods:
The present cross-sectional study included patients with advanced periodontal disease indicated for periodontal surgeries. Bone defects were measured first with the help of CBCT software and then, during a surgical intervention using the standardized UNC-15 periodontal probe and compared.
Statistical Analysis:
Statistical analysis was done using SPSS version 18.0 (SPSS Inc., Chicago, IL, USA). Both the measurements were compared with the help of Student’s t-test. P < 0.05 was considered statistically significant while P < 0.001 was considered highly statistically significant.
Results:
The palatal/lingual sites in anterior teeth which showed a mean CBCT value of 4.0444 mm and mean surgical value of 4.1822 mm revealed the mean difference to be statistically significant along with the distal sites which showed a mean CBCT value of 3.3667 mm and mean surgical value of 3.5217 mm (P = 0.001). The values, although in case of posterior teeth, were not found to be statistically significant.
Conclusion:
From the observations made from the present study, it could be concluded that CBCT provided good accessibility to visualize sites which were otherwise difficult to access during surgery. Furthermore, the bone density/volume could be detected precisely with the CBCT software which was otherwise not possible with the conventional methods.
