A material of 322 patients with 400 avulsed and replanted permanent teeth were followed prospectively in the period from 1965 to 1988 (mean observation period = 5.1 yrs). The age of the patients at the time of replantation ranged from 5 to 52 yrs (mean = 13.7 yrs and median = 11.0 yrs). Standardized patient records were used through the entire period in order to obtain valid data concerning the extent of injury and treatment provided. At the follow-up period, pulpal and periodontal healing were monitored by clinical examination, mobility testing and standardized radiographic controls. Thirty-two of the replanted teeth (8%) showed pulpal healing. When related to teeth with incomplete root formation, where pulpal revascularization was anticipated (n = 94) the frequency of pulpal healing was 34%. Periodontal ligament healing (i.e. with no evidence of external root resorption) was found in 96 teeth (24%). Gingival healing was found in 371 teeth (93%). During the observation period, 119 teeth (30%) were extracted. Tooth loss was slightly more frequent in teeth with incomplete root formation at the time of replantation than in teeth with completed root formation.
1965年至1988年期间，对322例患者的400颗脱位再植恒牙进行了前瞻性随访（平均观察期 = 5.1年）。再植时患者年龄在5岁至52岁之间（平均 = 13.7岁，中位数 = 11.0岁）。在整个期间使用标准化的患者记录，以获取有关损伤程度和所提供治疗的有效数据。在随访期间，通过临床检查、松动度测试和标准化的影像学检查来监测牙髓和牙周的愈合情况。32颗再植牙（8%）显示牙髓愈合。与预期牙髓血管再生的牙根未完全形成的牙齿（n = 94）相关时，牙髓愈合的频率为34%。96颗牙齿（24%）发现牙周膜愈合（即无牙根外部吸收迹象）。371颗牙齿（93%）发现牙龈愈合。在观察期内，拔除了119颗牙齿（30%）。再植时牙根未完全形成的牙齿的失牙情况比牙根已完全形成的牙齿略为常见。
