OBJECTIVE
To assess the association between the frequency and severity of dental fluorosis (DF) and molar incisor hypomineralization (MIH) in a fluoridated salt region.
STUDY DESIGN
In this retrospective cross-sectional study, we evaluated the buccal, occlusal/incisal, and palatal/lingual surfaces of first permanent molars and permanent incisors of 453 patients aged 13-16 years through intraoral standardized photographs. Two standardized examiners evaluated DF and MIH independently, utilizing the Thylstrup-Fejerskov (TF) index and the MIH index. The statistical analysis was performed using a generalized linear model and logistic regression adjusted for age, sex, and dental caries experience.
RESULTS
The MIH frequency at the surface level was lower in the presence of DF (PR= 0.03; P= 0.00, 95% CI: 0.01-0.08). At the surface level, MIH severity was lower among those presenting mild DF (aOR= 0.02; 95% IC: 0.01-0.07). Regarding severe DF, we found no significant difference in MIH severity (P= 0.174).
CONCLUSION
MIH frequency and severity tend to be lower in the presence of DF.
目的
评估在使用氟化物盐的地区，氟斑牙（DF）的频率和严重程度与磨牙切牙釉质发育不全（MIH）之间的关联。
研究设计
在这项回顾性横断面研究中，我们通过口腔内标准化照片评估了 453 名 13-16 岁患者的第一恒磨牙和恒切牙的颊面、咬合/切端和腭/舌面。两名标准化检查者使用 Thylstrup-Fejerskov（TF）指数和 MIH 指数独立评估 DF 和 MIH。使用广义线性模型和逻辑回归调整年龄、性别和龋齿经历进行统计分析。
结果
在存在 DF 的情况下，MIH 的表面水平发生率较低（PR=0.03；P=0.00，95%CI：0.01-0.08）。在表面水平上，存在轻度 DF 的患者的 MIH 严重程度较低（aOR=0.02；95%IC：0.01-0.07）。对于严重的 DF，我们没有发现 MIH 严重程度的显著差异（P=0.174）。
结论
DF 存在时，MIH 的频率和严重程度往往较低。
