摘要

恆牙第一大臼齒是口腔內長出的第一顆恆齒，這顆牙齒並未取代任何乳牙，故家長往往誤認為乳牙而忽視它。面對新萌發之「六歲齒」的深度齲齒，若能慎選適合病例，覆髓術的使用可以得到相當高的成功率。本病例報告介紹一位七歲七個月之男童，其下顎兩側新萌發之恆牙第一大臼齒被診斷為咬合面深度齲齒，分別使用直接及間接覆髓治療，可以見到覆髓術成功地保留牙髓活性，使得牙根發育成熟完全，避免了當初可能的複雜根管治療，提供在混合齒列時期恆牙牙根尚未發育完全時的階段性治療。

The first permanent molars are emerging in the oral cavity without precursory teeth and often mistaken as primary teeth. The progression of occlusal caries would be rapid due to the micromorphology of the pit and fissure. (There will be high success rate if operator can choose the suitable case of deep occlusal caries in immature permanent molar for pulp capping.) The pulp capping would be a successful procedure to treat certain deep caries of young permanent molars and preserve their vitality. This case presents a 7-year-and-7-month-old boy diagnosed with deep
occlusal caries in both mandible permanent first molars with opened apical foramens. By the direct and indirect pulp capping in either tooth, we successfully kept the pulp vitality, made the root formation complete and avoid the possibility of complex of endodontic treatment. Through proper diagnosis and case selection, pulp capping provides a tentative treatment for immature permanent teeth with deep caries in the mixed dentition.
