本文对Flemish儿童进行回顾性影像学研究,旨在检查乳磨牙周围的骨水平和骨丢失的影响因素。

研究对2896张18岁以下儿童的口内放射片进行筛选以确定符合纳入标准。研究者测量釉牙骨质界到牙槽嵴的距离,并对牙齿表面进行了检查,以确定骨水平相关的局部危险因素。根据以前的文献,距离>2mm定义为骨丢失。所有检测均由两名检查员进行。

结果发现,共有796名患者(平均年龄6.46±2.38岁)的1491张放射片纳入研究。釉牙骨质界到牙槽嵴顶的距离为0.07-2.88mm,平均距离为0.93± 0.37mm。这一距离与年龄呈正相关关系(p< .001)。3.5%的患者诊断为骨丢失。龋齿、填充物和牙髓病理学与骨吸收和釉牙骨质界到牙槽嵴顶的距离有关(p< .05)。

因此,乳牙牙槽骨丢失的发病率较低。骨水平和骨丢失均与局部因素密切相关。
