The amount of occlusal surface area covered when fissure sealant is applied to a tooth has not been previously reported. This study measured the occlusal surface area and sealant surface area using a computer-driven profilometric system. Twenty-two recently erupted, caries-free premolars were used. The mean occlusal area for all premolars was 34.34 mm2 +/- 4.42 mm2. The mean surface area of applied sealant for all teeth was 8.06 mm2 +/- 1.67 mm2, and the mean percentage of occlusal surface area covered by sealant was 23.97% +/- 5.02%. The occlusal surface area of mandibular first premolars was significantly smaller than that of the other premolar groups. However, this difference was not reflected in the area of sealant applied to premolars or in the percentage of occlusal surface covered by sealant. Mandibular first premolars required the same amount of coverage as the other tooth groups.
以往尚无关于在牙齿上应用窝沟封闭剂时所覆盖的咬合面面积的报道。本研究使用计算机驱动的轮廓测量系统测量了咬合面面积和封闭剂表面积。使用了22颗近期萌出、无龋的前磨牙。所有前磨牙的平均咬合面积为34.34平方毫米±4.42平方毫米。所有牙齿上所应用封闭剂的平均表面积为8.06平方毫米±1.67平方毫米，封闭剂覆盖的咬合面面积的平均百分比为23.97%±5.02%。下颌第一前磨牙的咬合面面积显著小于其他前磨牙组。然而，这种差异并未反映在应用于前磨牙的封闭剂面积或封闭剂覆盖的咬合面百分比上。下颌第一前磨牙所需的覆盖量与其他牙组相同。
