A case report is presented of a patient in whom nearly all teeth of the permanent dentition still present had short roots, while some teeth had never been formed at all. It may be concluded from the typical differences in length between the roots of the various teeth that this condition must be due to complete cessation of the growth of the teeth at the age of 7 or 8 years. Since the patient suffered a fulminant attack of erythema multiforme (STEVENS-JOHNSON syndrome) at this age, and since no other possible explanation of the short roots has been found, it is concluded that this clinical condition may have been the reason for the short root anomaly found. Damage or even destruction of the epithelial root sheath during the disease may be assumed to be the direct cause of the failure of full root development.
本文报告了一例患者，其恒牙列中几乎所有现存牙齿的牙根都很短，而有些牙齿根本就从未形成过。从不同牙齿牙根长度的典型差异可以推断，这种情况一定是由于在7或8岁时牙齿生长完全停止所致。由于该患者在这个年龄患了暴发性多形红斑（史蒂文斯-约翰逊综合征），且未发现其他可能导致牙根短的原因，因此得出结论，这种临床病症可能是所发现的牙根短异常的原因。可以假定疾病期间上皮根鞘的损伤甚至破坏是牙根完全发育失败的直接原因。
