“…Following initial SRP, a periodontal maintenance programme is recommended to maintain periodontal health and prevent the recurrence and progression of periodontitis in order to avoid tooth loss and to maintain or improve the probing depths (PDs) achieved following SRP (Axelsson & Lindhe, ; Becker, Berg, & Becker, ; Chambrone, Chambrone, Lima, & Chambrone, ; Chambrone & Chambrone, ; Lindhe & Nyman, ; McGuire, ). A previous study, on which this study is based, reported that a diet higher in fruits and vegetables, beta‐carotene, vitamin C, alpha‐tocopherol and fish oils (specifically the long‐chain omega‐3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) was positively associated with periodontal healing after SRP (Dodington, Fritz, Sullivan, & Ward, ). This positive association with fruits and vegetables may be due to higher intakes of flavonoids with known antioxidant and anti‐inflammatory properties; of particular interest is higher intakes of flavonoids as well as higher intakes of fruits and vegetables.…”
