OBJECTIVE
This cross-sectional study aimed to determine the prevalence of dental caries, dental fluorosis, and molar-incisor hypomineralization, and their associations in a group of Brazilian schoolchildren.
METHODOLOGY
Adolescents (n=411) were evaluated by two calibrated examiners for dental caries (DC), dental fluorosis (DF), and molar-incisor hypomineralization (MIH) using the CAST (Caries Assessment Spectrum and Treatment) instrument, Thylstrup and Fejerskov (TF) index, and MIH Severity Scoring System (MIH-SSS), respectively. Descriptive statistics, chi-square tests, and logistic regression were used for statistical analysis.
RESULTS
The sample comprised 42.75% boys and 57.25% girls. The prevalence of DC in permanent dentition was 94.75%, of which 29% were represented by dentin lesions. For DF, a prevalence of 40.75% was observed, with 69.32% mild, 12.88% moderate, and 17.79% severe. A positive association between the source of water and fluorosis was detected (p=0.01). The prevalence of MIH was 18%. Thirty adolescents (41.7%) presented with severe MIH. No association was found between DF or MIH and dentin DC or between MIH and DF at the individual level. However, a significant negative relationship was detected between DF and dentin carious lesions ( p <0.005) and DF and MIH ( p <0.00001) at the tooth level, whereas a positive association was observed between MIH and dentin carious lesions ( p <0.00001). A positive association was also observed between the severity of both conditions ( p <0.00001). Mild DF was the most prevalent problem observed. Cases of teeth with mild MIH were the most predominant in MIH-affected teeth.
CONCLUSIONS
No association was observed among the dentin carious lesions, MIH, and DF at the participant level. However, a positive association between MIH and dentin carious lesions was found at the tooth level, whereas MIH, DF, and DF and dentin carious lesions showed a negative relationship.
目的
本横断面研究旨在确定巴西一群学童的龋齿、氟斑牙和磨牙牙釉质发育不全的流行情况及其相关性。
方法
使用 CAST（龋病评估谱和治疗）仪器、Thylstrup 和 Fejerskov（TF）指数和 MIH 严重程度评分系统（MIH-SSS），由两名经过校准的检查者评估 411 名青少年的龋齿（DC）、氟斑牙（DF）和磨牙牙釉质发育不全（MIH）。采用描述性统计、卡方检验和逻辑回归进行统计学分析。
结果
样本包括 42.75%的男孩和 57.25%的女孩。恒牙龋齿的患病率为 94.75%，其中 29%为牙本质病变。DF 的患病率为 40.75%，轻度为 69.32%，中度为 12.88%，重度为 17.79%。发现水的来源与氟斑牙之间存在正相关（p=0.01）。MIH 的患病率为 18%。30 名青少年（41.7%）患有严重 MIH。DF 或 MIH 与牙本质 DC 之间，或 MIH 与个体水平的 DF 之间未发现相关性。然而，在牙齿水平上，DF 与牙本质龋损（p<0.005）和 DF 与 MIH（p<0.00001）之间存在显著负相关，而 MIH 与牙本质龋损（p<0.00001）之间存在正相关。在这两种情况的严重程度之间也观察到了正相关（p<0.00001）。轻度 DF 是最常见的问题。在受 MIH 影响的牙齿中，轻度 MIH 的牙齿最常见。
结论
在参与者水平上，牙本质龋、MIH 和 DF 之间没有相关性。然而，在牙齿水平上发现 MIH 与牙本质龋之间存在正相关，而 MIH、DF 和 DF 与牙本质龋之间存在负相关。
