饮食抗氧化成分与牙周病易感性的相关性

目的:通过对牙周病与非牙周病患者生活方式及饮食行为的调查,为牙周病的防治和辅助治疗提供依据。方法:随机选择本院门诊60例中、重度牙周病及60例牙周组织正常的就诊者,进行72h饮食问卷调查和饮食频率调查。采用SPSS13.0软件包对数据进行t检验和χ2检验。结果:牙周病组饮食摄入维生素C与正常对照组存在显著差异(P<0.05);饮食摄入β-胡萝卜素与正常对照组的差异具有统计学意义(P<0.05);饮食摄入类黄酮与正常对照组摄入的差异存在统计学意义(P<0.05);而饮食硒、锌摄入量与正常对照组虽存在差异,但无统计学意义。结论:饮食抗氧化营养素摄入与牙周健康关系密切,饮食维生素C、β-胡萝卜素、类黄酮含量越低,牙周组织炎症和破坏的发生率越高。

The relationship between dietary factors and susceptibility of periodontal disease

PURPOSE: A clinical survey was made on the life style and dietary behaviors of people with non-periodontal disease and people with periodontal disease for prevention and treatment of periodontal diseases.METHODS: 72-hour diet analysis and frequency analysis of dietary intake were performed in 60 patients with moderate-to-severe periodontal disease and 60 patients with healthy periodontal tissues randomly selected in the Ninth People’s Hospital for dental treatment.The data was analyzed by Student’s t test and Chi-square test with SPSS13.0 software package.RESULTS: There was significant difference(P<0.05) in vitamin C,flavonoids and β-carotene dietary intake between control group and periodontal disease group;In periodontal disease group,dietary intake of selenium and zinc intake was different from the normal control,but the difference was not statistically significant(P>0.05).CONCLUSIONS: There is a close relationship between oral health and antioxidant nutrients.Lower dietary vitamin C content,flavonoid content and β-carotene intake lead to destruction of periodontal tissue and higher incidence of periodontal disease.
