The aim of this study was to introduce a novel soft tissue thickness measurement method using cone beam computed tomography (CBCT) and to compare the new method with ultrasonic device applications and transgingival probing measurements.
Twenty-five participants (12 female, 13 male, age range, 25-51 years) were included the study. Soft tissue thickness in lateral incisor, canine, premolar, and molar regions were measured using transgingival probing (group T), ultrasonic device (group U), and CBCT scan measurements (group C). Differences and correlations between groups and agreement between measurement methods were evaluated.
Soft tissue thickness was significantly lower in group U in premolar region, but was significantly higher in molar region compared with group C and group T (P < .05). There were significant positive correlations in lateral incisor and canine region, between group U and group C, in premolar region between group T and group C, and in molar region between group U and group C, and between group C and group T (P < .05). The highest agreement between measurement methods was evident between group T and group C.
Soft tissue thickness values in maxilla may differ depending on the measurement method and location of the measurement. Ultrasonic device, transgingival probing, and CBCT measures may not necessarily correlate in all locations. The high agreement between CBCT measurements and transgingival probing may suggest the newly introduced method as a promising technique for soft tissue thickness evaluation.
This study evaluated the relation between different soft tissue thickness measurement methods and demonstrated a novel method which can be used in any part of the mouth. The outcome also suggested that the measurement method and the location might affect the soft tissue thickness value obtained, and therefore might be important in clinical decision making.
本研究旨在介绍一种使用锥形束计算机断层扫描（CBCT）的新型软组织厚度测量方法，并将新方法与超声设备应用和龈下探测测量进行比较。
本研究纳入了 25 名参与者（12 名女性，13 名男性；年龄 25-51 岁）。使用龈下探测（组 T）、超声设备（组 U）和 CBCT 扫描测量（组 C）测量侧切牙、尖牙、前磨牙和磨牙区域的软组织厚度。评估了组间差异和相关性以及测量方法之间的一致性。
在前磨牙区域，组 U 的软组织厚度显著低于组 C，但显著高于组 T（P<0.05）。在侧切牙和尖牙区域，组 U 和组 C 之间，在前磨牙区域，组 T 和组 C 之间，以及在磨牙区域，组 U 和组 C 之间，以及组 C 和组 T 之间均存在显著正相关（P<0.05）。测量方法之间的一致性最高的是组 T 和组 C。
上颌软组织厚度值可能因测量方法和测量位置而异。超声设备、龈下探测和 CBCT 测量方法在所有位置不一定相关。CBCT 测量和龈下探测之间的高度一致性表明，新引入的方法可能是评估软组织厚度的一种很有前途的技术。
本研究评估了不同软组织厚度测量方法之间的关系，并展示了一种可用于口腔任何部位的新型方法。结果还表明，测量方法和位置可能会影响获得的软组织厚度值，因此在临床决策中可能很重要。
