Mohammed M. A. Abdullah Al-Abdaly, Ali Mosfer A Alqahtani


Background: Chronic periodontitis occurs due to the reaction between bacterial components of dental plaque and the humoral and cellular host immune productions, such as cytokines and inflammatory mediators. Aim: The aim of this study is to evaluate the impact of qat (Catha edulis Forsk) chewing frequency on the status of chronic periodontitis. Materials and Methods: A total of 30 patients with chronic periodontitis were selected for this study and they were divided on the basis of qat chewing habits frequency into three equal groups, i.e., non qat chewing group (control group), qat chewing once daily and qat chewing twice daily. Plaque index (PLI), gingival index (GI), and Clinical attachment loss (CAL) were recorded. Gingival biopsies were obtained from selected site for assessing histopathological changes. The data were collect and analyzed by ANOVA test. Results: There were significant differences in PLI, GI, and CAL between qat chewing patients groups compared to non qat chewing patients group (control group). Histopathological study showed increased inflammatory cells in qat chewing patients groups compared to non chewing patients group. Conclusion: There was increased severity of chronic periodontitis with increased frequency of qat chewing habit daily there is a significance differences in clinical and histopathological findings between the patients in Group II and Group III (study groups) compared to Group I (control group). Clinical Significance: The current study reveal that the severity of chronic periodontitis may be increased with increased qat chewing frequency due to its traumatic effect on periodontal tissues.
