Tunnel restorations have been advocated as a conservative treatment modality for early carious lesions. However, the question arises as to quantity of dentin that remains within the marginal ridge above the tunnel path. In this experiment, extracted maxillary premolars with early carious lesions were sectioned and photographed. Measurements taken from tracings of the projected slides revealed that no dentin remained within the marginal ridge, irrespective of the direction of the tunnel path. These measurements indicate that the tunnel restoration is not a satisfactory treatment for proximal caries. The position of caries precludes the cutting of a tunnel preparation that leaves sufficient dentin under the marginal ridge, unless the bulk of enamel caries is left untouched.
隧道修复术已被提倡作为早期龋损的一种保守治疗方式。然而，关于在隧道路径上方的边缘嵴内剩余牙本质的量的问题出现了。在本实验中，对有早期龋损的拔除上颌前磨牙进行切片并拍照。从投影幻灯片的描图中进行的测量显示，无论隧道路径的方向如何，边缘嵴内均无牙本质残留。这些测量结果表明，隧道修复术并非近端龋的令人满意的治疗方法。龋损的位置使得无法制备出在边缘嵴下方留有足够牙本质的隧道，除非大部分釉质龋未受触动。
