BackgroundThe Oxidative Balance Score (OBS) is a comprehensive metric that assesses the state of a person's oxidative balance. This study aimed to investigate the relationship between the oxidative balance score and moderate and severe periodontitis in a representative sample of Korean adults.MethodsHealthcare big data from the 7th Korea National Health and Nutrition Examination Survey (2016–2018) was used, and 16,489 adults aged ≥19 years were included. Multivariate logistic regression analysis was performed to investigate the effect of sex‐specific oxidative balance scores on periodontitis.ResultsIn comparison with participants with a lower oxidative balance score, those with a higher oxidative balance score had a lower incidence of moderate and severe periodontitis (p < 0.05). After adjusting for covariates, the oxidative balance score was negatively associated with moderate (odds ratio [OR] = 0.952; 95% confidence interval [CI]: 0.934–0.971) and severe (OR = 0.958; 95% CI: 0.931–0.986) periodontitis; however, the result was not significant for severe periodontitis in women's (OR = 0.975; 95% CI: 0.934–1.018). Our study showed a statistically significant association between OBS and moderate and severe periodontitis, the small effect size should be interpreted with caution.ConclusionsThe oxidative balance score was associated with moderate and severe periodontitis in Korean adults. Therefore, managing this score may help reduce the risk of periodontitis.

韩国成年人的氧化平衡评分与牙周炎相关


背景氧化平衡评分（OBS）是评估一个人氧化平衡状态的综合指标。本研究旨在调查韩国成年人代表性样本中氧化平衡评分与中度和重度牙周炎之间的关系。方法使用第七次韩国国民健康和营养检查调查（2016-2018）的医疗保健大数据，对 16,489 名成年人进行了研究。 ≥19岁均被纳入。采用多因素logistic回归分析探讨性别特异性氧化平衡评分对牙周炎的影响。结果与氧化平衡评分较低的参与者相比，氧化平衡评分较高的参与者中度和重度牙周炎的发生率较低（ p < 0.05）。调整协变量后，氧化平衡评分与中度（比值比 [OR] = 0.952；95% 置信区间 [CI]：0.934–0.971）和重度（OR = 0.958；95% CI：0.931–0.986）呈负相关。牙周炎;然而，对于女性重度牙周炎，结果并不显着（OR = 0.975；95% CI：0.934–1.018）。我们的研究显示 OBS 与中度和重度牙周炎之间存在统计学上显着的关联，应谨慎解释较小的效应量。结论氧化平衡评分与韩国成人中度和重度牙周炎相关。因此，管理这个分数可能有助于降低牙周炎的风险。
