目的探讨锥形束CT（cone beam computed tomography，CBCT）测量腭部粘膜厚度的准确性，并建立一个能更准确测量腭部粘膜厚度的转换公式。然后，我们使用CBCT和转换公式评估了日本人群的腭粘膜厚度。材料与方法我们使用CBCT、数字印模和K文件评估了10名健康受试者15个部位的腭粘膜厚度。进行多元回归分析，以创建准确测量厚度的转换公式。然后，我们回顾性地获得了174例患者的CBCT数据，应用转换公式，并评估了腭粘膜厚度。结果测量部位影响测量误差。使用CBCT的测量值比实际测量值小0.34 ± 0.04 mm;因此，创建了转换公式。男性、年龄≥ 60岁、探诊袋深度≥ 4 mm与腭粘膜厚度有显著正相关;然而，未观察到探诊出血与腭粘膜厚度之间的相关性。结论CBCT可无创、准确地测量腭黏膜厚度。
AIM The purpose of this study was to investigate the accuracy of the measurement of palatal mucosa thickness using cone beam computed tomography (CBCT) and to create a conversion formula to evaluate palatal mucosa thickness more accurately. We then evaluated the palatal mucosa thickness in a Japanese population using CBCT and the conversion formula. MATERIALS AND METHODS We evaluated palatal mucosa thickness in 10 healthy subjects at 15 sites using CBCT, digital impression, and K file. Multiple regression analysis was performed to create a conversion formula to measure thickness accurately. We then obtained CBCT data from 174 patients retrospectively, applied the conversion formula, and evaluated palatal mucosa thickness. RESULTS Sites of measurement affected measurement error. Measurement using CBCT was 0.34 ± 0.04 mm smaller than actual measurement; therefore, a conversion formula was created. Male, age ≥ 60 years, and probing pocket depth ≥ 4 mm had significant and positive associations with palatal mucosa thickness; however, no association was observed between bleeding on probing and palatal mucosa thickness. CONCLUSION CBCT is useful for the noninvasive and accurate measurement of palatal mucosa thickness.
