The gingival tissues adjacent to the crowned and unrestored teeth were probed to determine individual pocket depths. The findings are listed here. (1) The average pocket depth adjacent to nonrestored teeth was 2.7 mm. The average pocket depth adjacent to teeth having crowns with subgingival margins was 3.4 mm. (2) Fifty-four nonrestored teeth had at least one pocket depth greater than 3 mm., while 84 crowned teeth had at least one or more measurements greater than 3 mm. (3) No positive relationship could be found between tooth brushing frequency and the pocket depth adjacent to teeth restored with complete cast crowns. (4) In nonrestored teeth, pocket depth increased with reduced frequency of tooth brushing. (5) Pocket depth increased with increased age of (a) the patient in both restored and nonrestored teeth and (b) the cast crown.
对与戴冠牙齿和未修复牙齿相邻的牙龈组织进行探测，以确定各个牙周袋深度。研究结果如下：(1) 与未修复牙齿相邻的平均牙周袋深度为2.7毫米。与龈下边缘有冠的牙齿相邻的平均牙周袋深度为3.4毫米。(2) 54颗未修复牙齿至少有一个牙周袋深度大于3毫米，而84颗戴冠牙齿至少有一次测量值大于3毫米。(3) 在使用全冠修复的牙齿中，刷牙频率与相邻牙齿的牙周袋深度之间未发现正相关关系。(4) 在未修复牙齿中，牙周袋深度随着刷牙频率的降低而增加。(5) 无论是修复牙齿还是未修复牙齿，(a) 患者年龄增加以及 (b) 铸造冠使用年限增加，牙周袋深度都会增加。
