Bitewing radiographs are the main tool for approximal caries detection. However, interpretation of findings is affected by numerous factors, such as beam angulation, exposure conditions, morphologic variations, etc. The objective of the present study was to compare the ability to detect virtually identical, artificial lesions in different tooth surfaces.
The in vitro model included preparation and radiologic evaluation of approximal artificial lesions in premolars and molars in depths ranging from 0.00 mm to 1.50 mm.
Significant differences were found in the prospect of a lesion detection between the different lesion depths (p < 0.0000) and between the different surfaces examined (p < 0.05). The interaction between lesion depth and tooth surface was significant at the 0.0001 level (ANOVA with repeated measures).
The results indicate that initial approximal lesions of uniform size are more readily detected in premolars than in molars and that the chance of an incipient lesion to remain undetected is twice as high in molars than in premolars.
咬合翼片是邻面龋检测的主要工具。然而，检查结果的解读受众多因素影响，如射线角度、曝光条件、形态变异等。本研究的目的是比较在不同牙面检测几乎相同的人工龋损的能力。
体外模型包括制备和放射学评估前磨牙和磨牙中深度范围为0.00毫米至1.50毫米的邻面人工龋损。
在不同龋损深度之间（p < 0.0000）以及在检查的不同牙面之间（p < 0.05），龋损检测前景存在显著差异。龋损深度和牙面之间的交互作用在0.0001水平上具有显著性（重复测量方差分析）。
结果表明，大小一致的早期邻面龋损在前磨牙中比在磨牙中更容易被检测到，且磨牙中早期龋损未被检测到的几率是前磨牙的两倍。
