概括
主要牙和永久牙的活跃病变显示出明显更高的粗度和较低的反射强度,而不是声音质. 这些差异可以通过触觉检查和客观方法可靠地检测,有助于病的诊断.
科学领域:
- 牙科研究 牙科研究
- 牙 诊断 牙 诊断 诊断
- 表面的表征表征 表面的表征
背景情况:
- 活跃的牙损病变具有明显的表面特征.
- 了解这些特征对于准确的诊断和管理至关重要.
- 原始 (落叶) 和永久牙都受到牙的影响.
研究的目的:
- 为了研究触摸感觉,表面粗度和反射强度之间的关系,在活跃的牙损病变.
- 为了比较初级牙和永久牙之间的这些特性.
- 评估触觉检查和客观方法的诊断效用.
主要方法:
- 精选的新摘取的牙 (初级和永久牙) 具有活跃的病变 (ICDAS分数为2).
- 使用3D激光扫描和多传感器显微镜测量表面粗度 (Ra,Sa,Vmc) 和垂直反射强度 (VRI).

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.

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...
