摘要:
目的 研究膜片定位牙龈测量锥形束计算机断层扫描(CBCT)影像法与口内扫描结合CBCT数字化叠加法(DIS-CBCT)在牙龈厚度测量中的一致性及精准性。方法 选取福建省级机关医院口腔医学中心患者20例共计600个位点,在区分唇及唇侧软组织的情况下,测量上前牙唇侧牙槽嵴顶冠方1 mm、牙槽嵴顶及牙槽嵴顶根方1 mm、2 mm、3 mm处的牙龈厚度。运用配对秩和检验分析两种方法测量牙龈厚度的差异,Pearson相关分析评价两种方法的相关性,两种方法测量的一致性则采用组内相关系数(ICC)进行分析。结果 膜片定位牙龈测量CBCT影像法与口内扫描结合CBCT数字化叠加法测得的牙龈厚度,中切牙区:口扫组牙龈厚度(1.241±0.310)mm,导板组牙龈厚度(1.241±0.310)mm; 侧切牙区:口扫组牙龈厚度(1.229±0.297)mm,导板组牙龈厚度(1.224±0.294)mm; 尖牙区:口扫组牙龈厚度(1.200±0.286)mm,导板组牙龈厚度(1.200±0.288)mm。口扫组牙龈厚度95%CI值分别为中切牙区(1.206,1.295)mm、侧切牙区(1.188,1.271)mm、尖牙区(1.160,1.240)mm; 膜片组中切牙区(1.197,1.284)mm、侧切牙区(1.183,1.265)mm、尖牙区(1.160,1.240)mm。两种测量方法在各牙位之间的差异均无统计学意义(P>0.05),两种方法表明唇侧牙龈厚度中切牙>侧切牙>尖牙。配对秩和检验中,两种测量方法中的中切区、侧切牙区、尖牙区Z值分别为-1.682、-1.236和-0.892,差异无统计学意义(P>0.005)。Pearson 相关分析显示两种方法测量唇侧牙龈厚度呈高度正相关(0.959、0.963、0.955,P<0.001)。两种方法的中切牙组、侧切牙组、尖牙组的组内相关系数ICC分别为 0.982、0.982和0.967,P<0.001。结论 膜片定位牙龈测量CBCT影像法与口内扫描结合CBCT数字化叠加法相关性极强,测量牙龈厚度的可重复性、一致性均较高,是一种可靠的牙龈厚度测量方法。
