Intrabony periodontal defects respond well to regenerative periodontal therapy. Numerous grafts and non graft materials are available for regeneration. Careful use of nonallogenic bone graft could enhance radiographic defect fill. Aim: To compare the clinical and radiographical evaluation of bovine derived xenograft (OsseograftTM) alone versus a combination of bovine derived xenograft and calcium sulphate hemihydrate (OsseomoldTM) in the treatment of intrabony defects in chronic periodontitis. Materials and Methods: A prospective, single blinded randomised clinical trial was conducted in the department of Periodontics, Nair Hospital Dental College, Mumbai, India (December 2017- August 2019). A total of 42 patients presenting with 43 intrabony defects were randomly assigned to Control Group (CG) (n=21) or Test Group (TG) (n=22). Clinical parameters {Probing Pocket Depth (PPD) and Clinical Attachment Level (CAL)} were assessed at baseline (M0), one month (M1), three months (M3) and six months (M6) and radiographic parameters {Bone Fill (BF)} were measured using Intraoral Periapical Radiograph (IOPA) at baseline (M0) and six months (M6). Two patients (three defects) were lost to follow-up. Descriptive and inferential statistical analyses were performed, results on continuous measurements were presented on Mean±SD. Statistical software IBM SPSS statistics 20.0. Level of significance was fixed at p=0.05. Student’s t-test was used to find the significant difference between and within the groups. Repeated measures Analysis of variance (ANOVA) was used to find the significance of study parameters within the group (at different time intervals). Results: PPD was lowest at six months for TG (3.95±0.61) and CG (3.30±0.66) and it gradually improved from baseline to six- months (p 0.5). BF was higher at M6 in TG (1.87) as compared to CG (1.72), which was statistically insignificant. Conclusion: Both treatments were clinically effective showing a significant improvement in clinical and radiographic parameters and there was significant difference between the two groups- clinically in terms of reduction in PPD and CAL gain at three months and six months with greater improvement seen in CG as compared to TG, with no difference radiographically. Further studies are needed to show the stability over time of the present results.
