Several anti-inflammatory drugs have been used to reduce pain and discomfort after periodontal surgeries. This study evaluates the efficacy of using etoricoxib and dexamethasone for pain prevention after open-flap debridement surgery. In this study, 60 patients who were undergoing open flap debridment surgery were randomly assigned to receive a single dose preoperative medication 1 hour prior to surgery. The patients were divided into three groups. In Group 1, 20 patients were given placebo drug orally. In Group 2, 20 patients were given 8 mg Dexamethasone orally and in Group 3, 20 patients were given 120 mg Etoricoxib orally. Patients were instructed to complete a pain diary hourly for the first 8 hours after each surgery and three times a day on the following 3 days. The four point verbal rating scale (VRS 4) and Numerical rate scale were used to assess discomfort. Post-operative Assessment of Pain and Discomfort showed that persistent discomfort and pain were found to be more in the placebo group compared to dexamethasone and etoricoxib group. The adoption of a preemptive medication protocol using either etoricoxib or dexamethasone may be considered effective for pain and discomfort prevention after open-flap debridement surgeries.
Aim:To evaluate immunohistochemically vascular endothelial growth factor (VEGF) and Ki-67 in human gingival samples and to compare these factors between healthy and diabetic patients.Materials and Methods:A total of 50 subjects were included in the study. They were categorized into three groups: Periodontally healthy group, periodontally diseased gingiva without any systemic disease group and periodontally diseased gingiva with controlled type II diabetes mellitus (DM) group. Gingival biopsies were performed and immunohistochemical analysis were done for VEGF and Ki-67 staining in gingival samples.Results:The present study found moderate intensity staining for VEGF in periodontitis group and periodontitis with controlled type II DM group and mild intensity staining for VEGF in periodontally healthy group. With regard to Ki-67, negative staining was observed in periodontally healthy group and mild staining in periodontitis group and periodontitis with controlled type II DM group.Conclusion:Further investigation needs to be conducted to identify how VEGF and Ki-67 are involved in the tissue inflammation associated processes and the relationship between VEGF and Ki-67 in progression of periodontitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
