概括

生物导向制备技术 (BOPT) 与下水平制备技术 (SHPT) 相比,显示出更好的长期牙周健康状况,尽管患者最初的满意度偏好了SHPT.

科学领域:

牙周病学牙周病学
恢复性牙科恢复性牙科
牙修复牙修复牙修复牙修复牙修复

背景情况:

牙科修复手术需要仔细考虑牙周健康.
牙下制备技术可能会影响牙健康和患者的治疗结果.
对比不同的制备方法对于优化治疗至关重要.

研究的目的:

为了比较下水平制备技术 (SHPT) 和生物导向制备技术 (BOPT) 的牙周健康结果.
在两年内评估斑块指数,探测深度,探测出血,临床附着水平和患者满意度.
评估SHPT与BOPT在分口设计中的长期影响.

主要方法:

一个分口研究设计,涉及100名患者接受两个冠冕,一个是SHPT,一个是BOPT.
随机将准备技术分配给牙,然后用芯和陶层复原.
临床参数包括斑块指数,探针深度,探针出血,临床附着水平和患者满意度在基线和治疗后1个月,3个月,6个月,1年和2年记录.

主要成果:

SHPT最初显示较低的斑块和炎症,但与BOPT相比,随着时间的推移显著增加.
患者满意度在基线时与SHPT更高,但在6个月和2年后显著下降.
最初,BOPT的探测深度较高,但在随访期间显著下降.

结论:

生物导向制备技术 (BOPT) 显示了有利的牙周行为和边际稳定性,用于全冠或面膜.
与SHPT相比,BOPT似乎是一个更可持续的技术来长期保持牙周健康.
虽然SHPT可能在患者满意度方面提供初步优势,但BOPT提供了优越的牙周结局.

Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Teeth

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...

Biofilms

Biofilms

Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...
