Item Restricted The Association Between Weight Loss and Periodontal Inflammation(Saudi Digital Library, 2023-12-01) Khoja, Fay; Suvan, JeanieBackground: Evidence reports an association between obesity and periodontal disease, however minimal research exists regarding the possible impact of weight loss through diet or bariatric surgery on periodontal condition. The aim of this study was to investigate the effect of weight loss through diet or surgery on periodontal health. Method: This study was a single centre quasi-experimental study with 6- and 12- weeks follow up recruited patients allocated to two groups; diet route and bariatric surgery route. Dental, social history, and periodontal examinations were carried out for each participant to determine their periodontal status. Masticatory function was assessed objectively (masticatory efficiency) using a validated colour-mixing chewing assessment and a validated self-reported questionnaire exploring participants oral health perception questionnaire (Dental habits, Obesity stigma in dental office, masticatory ability). Patient subsequently received bariatric surgery or a 12-week low-calorie diet. Six- and twelve-weeks following surgery or diet, the clinical and masticatory assessments were repeated. Results: This thesis will present partial findings of the ongoing study. The study recruited 7 participants living with obesity (4 in the diet group, 3 in the surgery group) all participants were recruited for baseline assessment, and 2 reported 6 weeks follow up (one from each group). The mean age in years within surgery and diet groups was 35.29 SD± 8.38, with weight mean range of 136.80 Kg SD± 10.3 and 129.53 Kg SD± 6.35 for surgery and diet groups respectively. Questionnaire analysis for obesity stigma in the dental office demonstrated 28.6% avoided dental care treatment due to feeling uncomfortable and reported that a dental care provider critiqued or insulted them regarding their weight. Conclusions: Due to the ongoing nature of this study, no conclusion can be reported regarding the influence of weight loss on the periodontal status. The self-reported questionnaire reported that one third of the enrolled participants faced discrimination related to their weight in the dental office.4 0
