Comparative evaluation of platelet-rich fibrin and autogenous bone graft for the treatment of infrabony defects in chronic periodontitis: Clinical, radiological, and surgical reentry

Context: Both intraoral autogenous bone grafting (ABG) and platelet-rich fibrin (PRF) offer a useful treatment modality for periodontal regeneration of intrabony defects (IBDs). However, predictable regeneration in patients with severe attachment loss is a challenge to the practitioners. Aim: The aim of this study was to compare the clinical efficacy of PRF with ABG for the treatment of IBDs in chronic periodontitis. Settings and Design: This is a randomized controlled trial. Materials and Methods: Twenty chronic periodontitis patients with IBDs were randomly treated by PRF or ABG. Probing pocket depth (PPD), relative attachment level (RAL), surgical reentry bone fill, and radiographic bone fill (RBF) were recorded at baseline, 3, 6, and 9 months postsurgery, respectively. Statistical Analysis: Student′s t-test was used for continuous variables. All means were expressed as mean ± standard deviation and proportions were expressed in percentage. The level of significance was set at P < 0.05. Results: Both PRF and ABG sites produced a significant improvement from baseline to 9 months for all the parameters. However, there was no significant difference between the two treatment modalities in the reduction of PPD and RAL gain at 9 months. In addition, ABG showed significantly greater RBF (30.34%) as compared to PRF (20.22%). Similar findings were supported by surgical reentry, where a surgical reentry of 65.31% at ABG sites and 43.64% at PRF sites was seen. Conclusion: Both ABG and PRF can be used predictably to reconstruct lost periodontal structures as indicated by PPD reduction and RAL gain. However, in terms of osseous defect fill, ABG yields more definitive outcome than PRF

Denture hygiene knowledge, attitudes, and practices toward patient education in denture care among dental practitioners of Jabalpur city, Madhya Pradesh, India

Context: Researchers have concentrated their focus on denture wearer's attitude and practice toward denture cleansing despite the fact that they should be more focused on the attitudes of the dentists' themselves towards patient education at the time of denture delivery. It is an obligation of every dentist to motivate, instruct and provide the means and methods of plaque control for their patients. Aims: The aim was to assess the denture hygiene knowledge, attitudes and practice towards patient education in denture care among dental practitioners (DPs) of Jabalpur city, Madhya Pradesh, India. Material and Methods: A total of 168 dental practitioners completed a comprehensive questionnaire. All participants signed an informed consent before answering the questionnaire. The institutional review committee approved the study. Statistical Analysis: Chi-square test for non-parametric study was employed to determine the statistical difference between the two groups. A P-value of 0.05 was considered to be statistically significant. Results: Most of the subjects were qualified with a bachelor degree 142 (85%). 25 (18%) subjects did not associate oral biofilms on complete denture with conditions like denture stomatitis and other serious systemic diseases. Approximately half of the DPs 69 (48%) and specialists 8 (31%) agreed that explaining denture hygiene instructions to old patients can be very time consuming. A recall program for their patients is of importance according to 39 (27%) of DPs and 3 (12%) specialists. Conclusions: It may be concluded that the study subjects had limited knowledge of denture cleansing materials and denture hygiene importance. Attitudes varied among the subjects when it came to sharing information with their patients
