Two cases are presented documenting the recognition and treatment of defects in the coronal portion of unerupted mandibular second permanent molars. The teeth were surgically exposed and the lesions treated as deep pit and fissure caries. Small, vital pulp exposures were encountered in both cases. Calcium hydroxide was placed and restoration with amalgam followed. Normal root formation and eruption occurred for 24 and 6 months, respectively. A firm diagnosis of caries, external resorption, or internal resorption could not be made because of the lack of histologic study.
本文报告两例下颌第二恒磨牙未萌出时冠部缺损的诊断与治疗情况。通过外科手术暴露牙齿，将病变当作深窝沟龋进行治疗。两例均出现小的、牙髓活力正常的穿髓点。放置氢氧化钙后用银汞合金修复。牙根分别在术后24个月和6个月正常形成并萌出。由于缺乏组织学研究，无法对龋齿、外部吸收或内部吸收做出确切诊断。
