龋齿的诊断

来源:[标签:来源] | 发布时间:2011-05-04 16:47:18 | www.chinesejk.com

  龋病是牙齿的硬组织(牙釉质、牙本质、牙骨质)在多种因素作用下逐渐被破坏的疾病。龋病是人类常见病,患龋病的牙齿亦称虫牙、蛀牙。龋病不仅使牙齿缺损,而且常伴有不同程度的疼痛,咀嚼功能障碍等,严重的还可以引起牙髓、牙槽骨及倾骨的炎症

  1.牙齿龋坏部位颜色由半透明的乳黄色变为白垩色、黄褐色或黑褐色。

  2.牙齿正常形态出现缺损,进而有龋洞形成。

  3.牙齿质地由光滑坚硬的表面变为松软乃至崩溃。

  4.x线检查龋损部位透射影。

  5.除浅龋外,对冷热酸甜有刺激痛,但龋坏牙齿无自发痛。
