《人体重伤鉴定标准》、《人体轻微伤鉴定标准》、《人体轻伤鉴定标准(试行)》规定不同程度的牙齿损伤所应认定的损伤程度,其前提条件应是正常牙齿。而行根管治疗后牙齿的不同结局,成为此类案件鉴定的关键。作者结合具体检案进行分析讨论。 The standards for the identification of serious injuries to human beings, the standards for the identification of minor injuries to the human body and the standards for the identification of minor injuries to human beings (for Trial Implementation) stipulate the degree of damage to be determined by different degrees of tooth damage, and the preconditions are normal teeth. The different outcomes of dental treatment after root canal treatment have become the key to the identification of such cases. The author combined with the specific prosecution for analysis and discussion.
