概括
整形手术暂时会影响牙脉的血液流动和敏感性,但预计将在六个月内完全恢复. 这表明程序后的暂时变化,而不是不可逆转的损害.
科学领域:
- 口腔和牙面部外科手术
- 牙科研究 牙科研究
- 牙周病学 牙周病学
背景情况:
- 整形手术可能会损害牙纸的活力.
- 评估脉血流 (PBF) 和脉敏感性 (PS) 在手术后至关重要.
研究的目的:
- 为了评估前牙的PBF和PS在整形手术后的变化.
- 为了确定外科骨切除术近距离对PBF和PS的影响.
主要方法:
- 对比了26名整形外科手术患者 (Le Fort I或BSSO) 和16名对照组.
- 使用激光多普勒流量计 (LDF) 和热测试 (CO2雪) 进行PBF和PS评估.
- 在多个时间点进行评估:手术前,4-5周,3个月,6个月手术后.
主要成果:
- 在对照组中没有观察到PBF或PS的显著变化.
- 手术患者在手术后的PBF和PS初始下降,随后在6个月后逐渐恢复到手术前水平.
- 在任何时间点上和下之间都没有发现PBF或PS的显著差异.
结论:
- 在骨架手术后,PBF和PS立即受到显著影响,但在六个月内完全恢复.
- 暂时的负面反应并不表示不可逆转的脉损伤.
- 在考虑内牙治疗之前,建议至少进行六个月的监测或使用LDF.

01:29Blood and Nerve Supply to the Bones
11.0K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

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...
