Comparative evaluation of bioglass with calcium sulphate β-hemihydrate for the treatment of intraosseous defects—a clinico-radiological study

BackgroundThe aim of the present clinical and radiological study was to compare bioglass and calcium sulphate β-hemihydrate in the treatment of intraosseous defect in chronic periodontitis.MethodA total of 50 subjects with bilaterally symmetrical periodontal osseous defects with probing pocket depth = 5 mm and intraosseous defects ≥ 3 mm as seen on the radiographs were undertaken for the study. In one site (group A) bioactive glass was placed in defect and in contralateral site (group B) calcium sulphate β-hemihydrate was used in the defect site.ResultsClinical improvement was noted in all patients at the end of study. Both the groups showed reduction in probing pocket depth, increase in clinical attachment level, and reduction in osseous defect. Both materials were effective in achieving osseous gain.ConclusionThe osseous gain in group A subjects was 58.93%, whereas in group B subjects it was 48.56%. Calcium sulphate β-hemihydrates showed promising results and were cost effective.
