文题释义:
锥形束CT:
又称Cone beam CT,是锥形束投照计算机重组断层影像设备,其原理是X射线发生器以较低的射线量(通常球管电流在10 mA左右)围绕投照体做环形数字式投照。然后将围绕投照体多次(180-360次)数字投照后“交集”中所获得的数据在计算机中重组后进而获得三维图像。CBCT是口腔头颅影像设备中最有前途和实用性的设备。
膜龈手术:是多种牙周软组织手术的总称,涉及附着龈、牙槽黏膜、系带或前庭沟区,这些手术也包括在牙周成形手术(periodontal plastic surgery)之内。膜龈手术的目的膜龈手术主要目的是加宽附着龈,覆盖裸露根面,治疗牙龈退缩,加深前庭沟,矫正系带或肌肉附着异常,以利于口腔卫生的保持和修复治疗的进行。

 

摘要
背景:
硬腭黏膜是牙周整形手术中结缔组织瓣的主要来源,其厚度是影响手术效果的关键。
目的:分析中国汉族人群硬腭黏膜厚度,并比较CBCT图像分析法与探查法的测量一致性。
方法:共招募30位汉族志愿者,总计300个牙位,使用CBCT图像分析法和探查法分别测量硬腭黏膜厚度,并分析两种方法的一致性。
结果与结论:①CBCT法测和探查法测得尖牙、第1前磨牙、第2前磨牙、第1磨牙及第2磨牙的硬腭黏膜厚度具有较高的一致性;②随着距离龈缘的距离增加硬腭黏膜逐渐增厚;③从尖牙到第2磨牙不断增厚,在尖牙处最薄,到第2磨牙处达到最厚;④研究首次测量中国汉族人群硬腭黏膜厚度,并证明探查法与CBCT图像分析法具有较高的一致性。

Abstract:

BACKGROUND: Hard palate mucosa serves as a main donor material in periodontal plastic surgery and its  thickness is crucial for the surgical outcomes.
OBJECTIVE: To analyze the thickness of hard palate mucosa in Han population, and analyze the consistency between cone-beam CT image analysis and trans-gingival probing method.
METHODS: A total of 30 Han volunteers (300 teeth) were recruited, and the thickness of hard palate mucosa was measured using cone-beam CT image analysis or trans-gingival probing method, to analyze their consistency.
RESULTS AND CONCLUSION: The two methods showed a higher consistency in the thickness of hard palate mucosa at the cuspid, first and second premolars as well as first and second molars. The thickness of the hard palate mucosa related to the distance from the gingival margin and tooth position, the thickness from the canine region to the second premolar region thickening gradually, and became the thickest at the second molar, and the thinnest at the cuspid. This study for the first time analyzed the thickness of hard palate mucosa in Chinese Han population, and confirmed there is a high consistency between cone-beam CT image analysis and trans-gingival probing method.
