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 grinding food.

Area of Science:

  • Dentistry
  • Digital Health
  • Artificial Intelligence

Background:

  • Accurate detection of Erosive Tooth Wear (ETW) is crucial for timely intervention.
  • The Basic Erosive Wear Examination (BEWE) has limited reproducibility in clinical settings.
  • Digital intraoral scans and AI offer potential for enhanced sensitivity and reliability in ETW assessment.

Purpose of the Study:

  • To evaluate the diagnostic accuracy and repeatability of AI-driven assessments of ETW using digital intraoral scans.
  • To compare AI and clinical assessments of BEWE scores and dentine exposure.
  • To determine the intra-examiner and inter-examiner reliability of digital scan assessments.

Main Methods:

  • A cross-sectional study involving 61 adults with varying degrees of ETW.
  • Intraoral scans were taken after clinical examination (BEWE and dentine exposure).
  • AI and human examiners independently assessed scans for BEWE and dentine exposure, with repeatability assessments.

Main Results:

  • On-scan assessments showed higher BEWE scores than clinical exams (37% vs 22.3%).
  • AI demonstrated perfect repeatability (ICC=1.00) for ETW assessment, outperforming human examiners (ICC=0.49-0.78).
  • AI achieved high sensitivity and specificity for dentine exposure detection (0.82/0.90).

Conclusions:

  • AI-derived assessments of ETW exhibit perfect repeatability and comparable accuracy to clinical methods.
  • Digital scans and AI tools show promise for earlier ETW diagnosis and improved patient monitoring.
  • AI enhances the assessment of dentine exposure, offering a valuable adjunct in dental diagnostics.
