To examine associations between periodontal disease severity and clinical and microbiological measures of caries in adults.
A cross-sectional study of 94 healthy adults ((mean ± SD) 55.4 ± 13.0 years) was conducted. Data were collected by means of questionnaire and a clinical examination that included the Decayed, Missing, Filled teeth Surfaces (DMFS) index, probing depth (PD), clinical attachment level (CAL), and gingival bleeding and plaque scores. Supra- and subgingival plaque samples were collected to assess the presence of Streptococcus mutans and six periodontal pathogens. Participants were subsequently categorized using Center for Disease Control and Prevention/American Academy of Periodontology (CDC-AAP) definitions and tertiles of percentage of sites with CAL ≥ 3mm.
Significant positive associations were found between the periodontal disease severity (CDC-AAP) and the DMFS (aOR = 1.03; 95% CI 1.01-1.05) and DS indices (aOR = 1.18; 95% CI 1.05-1.32) as well as between the tertiles of percentage of sites with CAL ≥ 3 mm and DMFS (aOR = 1.03; 95% CI 1.00-1.05) and DS indices (aOR = 1.12; 95% CI 1.00-1.25). A significant positive association was also found between oral levels of F. nucleatum and S. mutans (aOR = 6.03; 95% CI 1.55-23.45).
A small but positive association was found between clinical measures of caries and periodontal disease severity. Further research is warranted to examine the association between these two common oral diseases.
Periodontal diseases and caries are the two most common oral diseases. There was a positive association between clinical and microbiological markers of both diseases. Therefore, strategies in oral health education should involve both caries and periodontitis prevention.
探讨成年人牙周病严重程度与龋齿临床和微生物学指标的关系。
对 94 名健康成年人（（平均±标准差）55.4±13.0 岁）进行横断面研究。通过问卷调查和临床检查收集数据，包括龋失补牙面（DMFS）指数、探诊深度（PD）、临床附着水平（CAL）、牙龈出血和菌斑评分。采集龈上和龈下菌斑样本，以评估变形链球菌和六种牙周病病原体的存在情况。参与者随后根据疾病控制与预防中心/美国牙周病学会（CDC-AAP）的定义和 CAL≥3mm 位点百分比的 tertiles 进行分类。
牙周病严重程度（CDC-AAP）与 DMFS（aOR=1.03；95%CI 1.01-1.05）和 DS 指数（aOR=1.18；95%CI 1.05-1.32）呈显著正相关，CAL≥3mm 位点百分比 tertiles 与 DMFS（aOR=1.03；95%CI 1.00-1.05）和 DS 指数（aOR=1.12；95%CI 1.00-1.25）也呈显著正相关。口腔水平的 F. nucleatum 和 S. mutans 之间也存在显著正相关（aOR=6.03；95%CI 1.55-23.45）。
龋齿的临床指标与牙周病严重程度之间存在较小但呈正相关。需要进一步研究以检查这两种常见口腔疾病之间的关联。
牙周病和龋齿是最常见的两种口腔疾病。两种疾病的临床和微生物学指标之间存在正相关。因此，口腔健康教育策略应同时涉及龋齿和牙周炎的预防。
