Despite intensive efforts for categorizing demarcated enamel opacities, often related to molar incisor hypomineralization (MIH), there is a lack of descriptive criteria aiming to describe them physically outside the scope of color and size. This is most likely due to the indices focusing on molar, not anterior, teeth.
To map and classify demarcated lesions on permanent anterior teeth using reflected and transilluminated light. The association between classification and related lesion characteristics was also examined.
Permanent anterior teeth with demarcated opacities related to MIH were selected. For each tooth, standardized photographs were taken using transmitted and reflected light. Each lesion was mapped and classified according to its color, lesion size, surface integrity, and type. The data were analyzed using the chi-square and Fisher's exact tests. A logistic regression analysis was performed to identify the risk of PEB.
There were significant relationships between lesion size, color, and type with surface integrity. Lesion type and size were more important than lesion color for assessing the risk of PEB. There was also a significant relationship between lesion size and lesion color.
Lesion size and type are significant clinical parameters for assessing the risk of PEB on enamel opacities related to MIH.
尽管人们已经做出了巨大的努力来对界限明确的釉质变色进行分类，这些变色通常与磨牙牙釉质发育不全（MIH）有关，但仍缺乏针对这些变色的物理特征（除颜色和大小外）的描述性标准。这很可能是因为现有的分类指数主要针对磨牙，而非前牙。
利用反射光和透射光来定位和分类恒牙前牙的界限明确病变。同时还研究了分类与相关病变特征之间的关系。
选择与 MIH 相关的永久性前牙的界限明确的釉质变色。对于每颗牙齿，使用透射光和反射光拍摄标准化照片。根据颜色、病变大小、表面完整性和类型对每个病变进行定位和分类。使用卡方检验和 Fisher 精确检验对数据进行分析。进行逻辑回归分析以确定 PEB 的风险。
病变的大小、颜色和类型与表面完整性之间存在显著的关系。病变类型和大小对于评估 PEB 的风险比病变颜色更为重要。病变大小和颜色之间也存在显著的关系。
病变大小和类型是评估与 MIH 相关的釉质变色的 PEB 风险的重要临床参数。
