将这些干预措施与对照组进行比较,用于V类树脂复合材料在初级牙中的修复.

主要方法:

60个初级牙被分为控制,G-Coat Plus和Er:YAG激光组.
使用Z250树脂复合材料修复了带有牙和牙边缘的V类腔.
牙经历了热循环,染料浸泡,切割和立体显微镜评估微泄漏.

主要成果:

与对照组和激光组相比,G-Coat Plus在所有边缘显著减少了微漏.
与对照组相比,Er:YAG激光预处理没有显示微漏的显著差异.
牙 (牙) 边缘显示出比闭口 (乳) 边缘更大的微漏,除了G-Coat Plus组.

Assessment of the Mouth

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Microcracking in Concrete

Microcracking in Concrete

Microcracking in concrete refers to the tiny cracks that can form within the material even before any external load is applied. These microcracks typically occur at the interface between the coarse aggregate and the hydrated cement paste, often as a result of differential volume changes prompted by variations in stress-strain behavior, as well as thermal and moisture movement. Initially, these microcracks remain stable and do not grow substantially until the concrete is stressed to about 30...

Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
