Scientific reports
|November 22, 2023
概括
蓝光照射提供了一种侵入性最小的根管清洁方法,可以保持牙结构. 虽然它与甲 (NaOCl) 灌效率不匹配,但它降低了微生物负载,使其成为重要的牙的潜在选择.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 生物材料科学 生物材料科学
- 微生物学 微生物学
背景情况:
- 传统的根管制备涉及仪器仪表,这可以改变牙的化学和微观结构性质.
- 正在探索非仪器技术,以尽量减少侵入性,同时确保有效的消毒.
研究的目的:
- 研究蓝光照射作为根管清洁的非仪器技术的有效性.
- 评估光线应用和仪器对根管牙化学和微观结构的影响.
- 评估不同根管制备和消毒方法的抗菌疗效.
主要方法:
- 人类单根牙接受了各种处理:蒸水,二化物 (NaOCl),加热NaOCl,NaOCl + EDTA,带或不带仪器,以及在没有仪器后的激光应用.
- 使用能量分散光谱 (EDS) 和富里埃变换红外光谱 (FT-IR) 分析了丹丁的化学成分.
- 通过扫描电子显微镜 (SEM) 检查了表面微观结构.
- 通过微生物测试确定了抗微生物疗效.
主要成果:
- 蓝光应用没有改变根管牙中的/,碳酸盐/或胺I/的比例,保留了其原始化学和微观结构.
- 仪器仪表显著降低了碳酸盐/酸盐和胺I/酸盐的比率,无论灌溶液或技术如何.
- 仅用蓝光就无法达到与NaOCl灌相同的抗菌效率.
- 在有或没有仪器的情况下,NaOCl灌显著降低了细菌负载.
结论:
- 使用蓝光消毒的非仪器化根管制备可以保持牙的化学和微观结构完整性.
- 虽然蓝光显示了对最小侵入性内牙治疗的潜力,但NaOCl灌仍然优于细菌减少.
- 将最小侵入性准备与光消毒和液压水泥密封器相结合,可能为需要根管治疗的关键牙提供一个有吸引力的替代方案.

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...
