The purpose of this in vivo study was to identify a previously unreported occlusal enamel ridges in the mesial fossa of the maxillary first permanent molars by using caries detector dye. Seventy two maxillary right and left first permanent molars of thirty-six patients were examined in this study. Horizontal linear measurements in millimeters, location, and shape of the occlusal ridge in the mesial fossa were examined clinically and were compared to the transverse ridge in a percentage form. Five occlusal enamel ridges with different locations, and pathways were detected in addition to the transverse ridge, two major ridges (> 33.33% of the transverse ridge) and three minor ridges (< 33.33%) of the transverse ridge). There were symmetrical patterns of the ridges between right and left maxillary first permanent molars (80.5%).
本体内研究的目的是通过使用龋病检测染料来识别上颌第一恒磨牙近中窝中以前未报道过的咬合釉质嵴。本研究检查了36名患者的72颗上颌左右第一恒磨牙。临床上检查了近中窝中咬合嵴的毫米水平线性测量值、位置和形状，并以百分比形式与横嵴进行比较。除横嵴外，还检测到五条位置和走向不同的咬合釉质嵴，即两条主要嵴（>横嵴的33.33%）和三条次要嵴（<横嵴的33.33%）。上颌左右第一恒磨牙之间的嵴存在对称模式（80.5%）。
