Dietary modification may be important in the prevention and control of chronic adult periodontitis. The role of promoting an adequate consumption of fruits, vegetables and whole grains in chronic periodontitis has not been thoroughly investigated. The main aim of this dietary intervention study was to assess the influence of a customised dietary intervention (aiming to increase the consumption of fruits, vegetables and whole grains) on antioxidant status in adults with chronic periodontitis.
Fifty-one participants, aged 30-65 years, were recruited from a U.K. Dental Hospital and randomly allocated to an intervention or control group. Both groups received normal clinical treatment but customised dietary advice was delivered to the intervention group by a community nutrition assistant. Dietary intakes, anthropometric parameters and biochemical indices with respect to blood and saliva and periodontal indices were evaluated at baseline, as well as at 3 and 6 months post-dietary intervention.
At 3 and 6 months post-intervention, the intervention group showed a significant (P < 0.05) increase in plasma total antioxidant capacity measured by Trolox equivalent antioxidant capacity assay compared to the control group. At 3 and 6 months after dietary intervention, the intervention group had significantly higher intakes of fruits and vegetables compared to the control group. The intake of whole grain was significantly higher in the intervention group than in the control group, 6 months post-intervention. No significant differences were observed with respect to periodontal indices between groups.
It is suggested that dietary advice may help to improve dietary habits and, consequently, the antioxidant status of patients with chronic periodontitis. However, the impact of such intervention on periodontal indices needs further investigation.
饮食调整对于慢性成人牙周炎的预防和控制可能至关重要。促进水果、蔬菜和全谷物的充足摄入在慢性牙周炎中的作用尚未得到充分研究。这项饮食干预研究的主要目的是评估定制饮食干预（旨在增加水果、蔬菜和全谷物的摄入量）对慢性牙周炎成年人抗氧化状态的影响。
从英国一家牙科医院招募了51名年龄在30至65岁之间的参与者，并将他们随机分配到干预组或对照组。两组均接受常规临床治疗，但由社区营养助理向干预组提供定制的饮食建议。在基线时以及饮食干预后3个月和6个月，评估饮食摄入量、人体测量参数、血液和唾液的生化指标以及牙周指标。
干预后3个月和6个月，与对照组相比，干预组通过Trolox等效抗氧化能力测定法测得的血浆总抗氧化能力显著增加（P < 0.05）。饮食干预后3个月和6个月，干预组的水果和蔬菜摄入量显著高于对照组。干预后6个月，干预组的全谷物摄入量显著高于对照组。两组之间在牙周指标方面未观察到显著差异。
建议饮食建议可能有助于改善饮食习惯，从而改善慢性牙周炎患者的抗氧化状态。然而，这种干预对牙周指标的影响需要进一步研究。
