概括

破裂牙的内牙治疗显示出中等的长期存活率,有利的手术前探针深度显著改善了结果. 这种处理是一种可行的选择,特别是当初始探测深度小于4毫米时.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
牙科创伤学牙科创伤学
恢复性牙科恢复性牙科

背景情况:

破裂的牙在内牙科中构成了重大挑战.
关于内治疗破裂牙的生存和成功的长期数据有限.
确定预后因素对于治疗规划至关重要.

研究的目的:

为了评估长期 (10-15年) 的存活率和成功率的内牙治疗裂牙.
确定影响这些牙生存和成功的预后因素.

主要方法:

一项对196名患者进行的回顾性研究,其中204名患者有内治疗的破裂牙.
临床和放射性评估是在10-15年后续进行的.
考克斯比例危险回归分析了影响牙存活和愈合的因素.

主要成果:

10年生存率为66%,在15年后降至55%. 在同一时期,成功率从64%下降到37%.
手术前探测深度 (PD) 是一个关键的预后因素.
牙的PD<4毫米有显著更好的存活率 (76%在10年,64%在15年).
增加的PD (4-5毫米和≥6毫米) 和年龄较大与更高的牙损失风险有关.

结论:

对于有良好的手术前PDs的破裂牙的内牙治疗提供了与非破裂牙相比的长期存活率.
这种治疗方式是一种可行的,推的长期选择.
仔细的手术前对PD进行评估对于预测结果至关重要.

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
