ABSTRACT
BACKGROUND AND OBJECTIVES: Socket preservation is the procedure which is carried out at the time of extraction to enhance the esthetic predictability of prosthesis and to reduce the number of surgical interventions by minimizing the crestal bone loss. The aim of the present study was to compare the efficacy of natural bovine hydroxyapatite and platelet-rich fibrin (PRF) matrix along with collagen plug to unassisted natural healing in extraction sites. MATERIALS AND METHODS: A sample of 25 patients of age 17-50 years who require extraction of at least two teeth which were not adjacent to each other were included in the study. One site in each patient was subjected to ridge preservation procedure using Cerabone™ PRF along with collagen plug and the other site was subjected to atraumatic extraction alone. Parameters such as loss of ridge width and loss of ridge height were measured clinically and radiographically at baseline and after 6 months. RESULTS: The mean loss of width was found to be 2.75 mm (2.75 ± 1.49) at the control site compared to 1.47 mm (1.47 ± 1.44) at the test site. The test site showed 2.31 mm bone fill, (8.7%) compared to the control site. CONCLUSION: Within the limitations of the study, the results suggest that socket preservation procedure is a reliable method that minimizes the alveolar bone loss.
ABSTRACT
BACKGROUND: The relationship between diabetes and periodontitis has been studied for more than 50 years and is generally agreed that the periodontal disease is more prevalent in diabetic patients compared to nondiabetics. Vascular changes like increased thickness of basement membrane in small vessels has been reported in diabetic patients, but the quantity of blood vessels in gingiva of diabetic patients has not been discussed much. The aim of this study was to compare the number of blood vessels in gingiva between chronic periodontitis (CP) patients, CP with diabetes (type 2), and normal healthy gingiva. MATERIALS AND METHODS: The study included 75 patients, divided into three groups of 25 patients each-Group I with healthy periodontium (HP), Group II with CP, and Group III with CP with diabetes mellitus (CPDM). Gingival biopsies were obtained from the subjects undergoing crown lengthening procedure for Group I, and in patients with CP and in CPDM biopsies were collected from teeth undergoing extraction. Sections were prepared for immune histochemical staining with CD34. RESULTS: Difference was observed in the average number of blood vessels when compared between HP, CP, and CPDM groups. Statistical significant difference was observed when the HP and CP groups and HP and CPDM groups were compared. CONCLUSION: The results of the study indicated that the number of blood vessels in gingival connective tissue is significantly higher in CP and CPDM patients.
