Abstract

Objective: To assess differences in root development between the cleft side (CS) and noncleft side (NCS) for permanent maxillary central incisor and canine longitudinally in patients with nonsyndromic complete unilateral cleft lip and palate (cUCLP) who received secondary alveolar bone grafting (SABG) and to evaluate the effects of SABG on the acceleration of root development of these teeth.

Materials and methods: Permanent maxillary central incisors and canines of 44 subjects with nonsyndromic cUCLP who had all their cleft-related surgeries performed by the same surgeon were analyzed retrospectively from chart notes and radiographs. Panoramic and periapical radiographs at time point 1 (T1) (age, 7.55 years), at SABG (time point 2 [T2], 10.13 years), and a minimum of 2 years after SABG were studied. Root development rating scores on the NCS and CS were compared using paired t-tests and analyses of proportions.

Results: Mean root development score differences (NCS - CS) for canines and central incisors were greatest at T2 but diminished at time point 3 (T3). A larger proportion of teeth on the CS trailed the teeth on the NCS by at least 1 point at T2 than at T1 or T3, with the smallest proportion being observed at T3. The change in root development scores from T1 to T2 and from T2 to T3 showed relative CS acceleration from T2 to T3, indicating a catch-up of root development of cleft-adjacent teeth after SABG.

Conclusions: Root development of cleft-adjacent central incisors and canines is slow in comparison with their noncleft analogs. Root development of these teeth accelerates following SABG.

在接受二次牙槽骨移植的非综合征唇腭裂患者中，与非唇腭裂侧类似牙齿相比，唇裂侧相邻牙齿的牙根发育差异。

目的评估接受过二次牙槽骨移植术（SABG）的非综合征完全性单侧唇腭裂（cUCLP）患者裂侧（CS）和非裂侧（NCS）上颌恒中切牙和犬齿牙根发育的差异，并评估 SABG 对加速这些牙齿牙根发育的影响：根据病历记录和 X 光片对 44 名非综合征 cUCLP 受试者的永久上颌中切牙和犬齿进行了回顾性分析，这些受试者的所有唇裂相关手术均由同一名外科医生完成。研究对象分别接受了时间点 1（T1）（年龄 7.55 岁）、SABG（时间点 2 [T2]，10.13 岁）和 SABG 术后至少 2 年的全景和根尖周 X 光片检查。使用配对 t 检验和比例分析比较了 NCS 和 CS 的牙根发育评分：结果：犬齿和中切牙的平均牙根发育评分差异（NCS - CS）在第 2 个时间点最大，但在第 3 个时间点（T3）缩小。与时间点 1 或时间点 3 相比，时间点 2 在 CS 上落后 NCS 至少 1 分的牙齿比例更大，而时间点 3 的比例最小。牙根发育评分从T1到T2以及从T2到T3的变化显示，从T2到T3，CS相对加快，这表明SABG后，牙裂邻接牙齿的牙根发育迎头赶上：结论：与非唇裂类似牙相比，唇裂邻接中切牙和犬齿的牙根发育缓慢。SABG术后，这些牙齿的牙根发育会加快。
