摘要
目的 :研究上颌侧切牙畸形根面沟的外形。方法 :13个有畸形根面沟的上颌侧切牙 ,在放大镜、显微镜下观察结构。结果 :12个牙有牙本质变薄 ,牙骨质不连续。结论 :因畸形根面沟易产生牙体 -牙髓病 ,牙周病 ,须注意预防性治疗。
AIM:To study the morphology of deform root groove in the maxillary lateral incisors.METHODS:13 deform root groove teeth were observed with macroscopy and microscopiy.RESULTS:Dentin was thinner and cemment was discontinuous in 12 teeth.CONCLUSION:Deform root grooves were easy to getdisease of pulpitis or periodontitis.
