Abstract

Aim: The present study was to evaluate histologically and histometrically the efficacy of Chitra granules in the regeneration of alveolar bone and to compare it with that of OsteoGenR (HA Resorb)™ in iatrogenically created alveolar bone defects in mongrel dogs.

Materials and Methods: Four dogs (16 sites) were used for this split-mouth study. The animals were divided randomly into two groups of two animals. Same animals were used as control and test. Each dog had four implantation sites. The periodontal defects were prepared by acute defect model. Animals were sacrificed at 3 months (n=2), 6 months (n=2) and histologic and histometric evaluation was carried out.

Statistical Analysis: The data was analysed using statistical package Graph pad Software. Comparison of the hard and soft tissue parameters in the two groups was done using the Wilcoxan (Man Whitney), two tailed t-test. A p-value less than 0.05 were considered significant.

Results: Maturing bone with immature periodontal ligament fibers were observed at three months and advanced osteogenesis at six months with both the types of bone graft materials. The mean values showed that amount of new bone formed with OsteoGenR (HA Resorb)™ was slightly more than that obtained by Chitra granules in histometric evaluation.

Conclusion: Histological study showed similar healing pattern with both the types of bone graft materials with maturing bone at 3 months and advanced osteogenesis at six months in experimental intraosseous periodontal defects in dogs. However, histological evaluation for longer period is necessary to determine the time taken for complete replacement of the bone graft materials with new bone.
