概括

使用矿物三氧化聚合物 (MTA) 或BiodentineTM的生命脉疗法对创伤性损伤的未成熟牙显示出有前途,即使在延迟10天后. 在一系列病例中,这些治疗成功地保持了牙活力,并促进了根部的发育.

科学领域:

牙科牙科是指牙科的专业.
牙周内科医院牙周内科医院牙周内科医院
儿科牙科儿科牙科

背景情况:

创伤性牙损伤经常导致不成熟的永久前牙的脉暴露.
生命脉疗法 (VPT),特别是脉切除术,可以保护脉功能,有助于牙沉积,并促进牙保留.
延迟治疗可能会因为细菌污染和炎症而损害VPT的结果.

研究的目的:

评估在不成熟的永久牙中进行全脉切除术的临床和放射性结果,牙骨折复杂,治疗延迟长达10天.
为了比较矿物三氧化物聚合物 (MTA) 和BiodentineTM在这些病例的生命脉治疗中的疗效.

主要方法:

一系列病例涉及七名患有复杂皇冠骨折的七名患者 (年龄为8.5-9.5岁) 的八个不成熟的上中央切口.
使用MTA或BiodentineTM进行全脉切除术,然后尽可能恢复和重新连接碎片.
在最多24个月的间隔内进行临床和放射性随访.

主要成果:

所有经过治疗的牙在18-24个月后仍然具有重要作用,症状消失,表现出持续的根部发育 (apexogenesis).
在三颗牙上进行了牙桥梁的放射观察.
没有发现任何病理性变化,如周周放射性或胀;一个病例出现冠状变色.

结论:

用MTA或BiodentineTM进行全脉切除似乎是对创伤暴露的未成熟牙的可行治疗方法,即使延迟了10天.
由于研究的局限性,需要进一步研究更大的样本大小和更长的随访时间.

关键词:

这是一种脉冲切除术 (pulpotomy).这就是Apexogenesis.复杂的皇冠骨折复杂的皇冠骨折一个创伤的创伤创伤.年轻的牙,年轻的牙.

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...
