Abstract

OBJECTIVES

To determine root lengths of fully developed permanent teeth of cleft lip and palate (CLP) patients and to define their crown-root (C/R) ratios.

METHOD

Crown height and root length of permanent teeth were measured from panoramic radiographs of 44 CLP patients and 37 controls. A total of 1397 teeth were measured, and C/R ratios were calculated.

RESULTS

Higher C/R ratios were found in CLP patients; this was statistically significant for both maxillary and mandibular incisors and canines. Bilateral CLP subjects showed higher C/R ratios in general than unilateral CLP subjects. Roots of maxillary incisors, canines, and some other teeth were significantly shorter in CLP patients than in controls.

CONCLUSIONS

CLP patients should be considered to have unfavorable C/R ratios, which could be the result of short root lengths for some teeth.

摘要

目的

确定唇腭裂（CLP）患者恒牙的根长，并确定其冠根比（C/R）。

方法

从 44 例 CLP 患者和 37 例对照者的全景片上测量恒牙的牙冠高度和根长。共测量了 1397 颗牙齿，并计算了 C/R 比值。

结果

CLP 患者的 C/R 比值较高；上颌和下颌切牙和尖牙的差异具有统计学意义。双侧 CLP 患者的 C/R 比值一般高于单侧 CLP 患者。CLP 患者的上颌切牙、尖牙和其他一些牙齿的根明显比对照组短。

结论

CLP 患者的 C/R 比值应被认为是不利的，这可能是一些牙齿根长较短的结果。
