Tooth Anatomy

485
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...

Teeth

434
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...

Area of Science:

  • Dental Medicine
  • Biomedical Engineering
  • Machine Learning in Healthcare

Background:

  • Tooth decay (dental caries) is a prevalent oral health issue requiring early diagnosis.
  • The disease involves the breakdown of tooth tissues due to bacteria and sugars.
  • Existing image-based detection methods have shown limitations.

Purpose of the Study:

  • To develop and evaluate a novel feature-based approach for enhanced tooth decay detection.
  • To leverage Principle Component Analysis (PCA) and Chi-square (chi2) for feature engineering.
  • To assess the efficacy of a voting classifier ensemble for caries detection.

Main Methods:

  • Utilized feature-based datasets instead of image-based ones.
  • Employed Principle Component Analysis (PCA) for feature generation.
  • Implemented a voting classifier ensemble including Extreme Gradient Boosting (XGB), Random Forest (RF), and Extra Trees Classifier (ETC).

Main Results:

  • The proposed voting classifier with PCA features achieved high performance metrics.
  • Achieved accuracy of 97.36%, precision of 96.14%, recall of 96.84%, and F1 score of 96.65%.
  • Outperformed approaches using chi2 features and other machine learning models.

Conclusions:

  • Feature-based datasets with PCA and a voting classifier ensemble significantly improve tooth decay detection accuracy.
  • The model shows strong potential for effective dental caries diagnosis.
  • This study offers innovative insights for advancing dental healthcare through improved diagnostic methodologies.
