Assessment of the Mouth01:26

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.

Area of Science:

  • Oral Health
  • Artificial Intelligence
  • Public Health

Background:

  • Periodontitis affects nearly half of American adults, with many lacking access to timely dental care.
  • Current diagnostic methods require clinical settings and professional expertise, limiting accessibility.
  • Untreated periodontitis can lead to severe systemic health complications.

Purpose of the Study:

  • To develop a machine learning (ML) tool for accessible, at-home preliminary periodontitis assessment.
  • To address the gap in dental care access, particularly for periodontal examinations.
  • To empower individuals with undiagnosed periodontal conditions to seek timely treatment.

Main Methods:

  • Trained an ML model using multimodal, radiographic-independent features from the NHANES database.
  • Labeled individuals by periodontitis severity based on periodontal charting records.
  • Engineered features and conducted hyperparameter searches for optimal model performance.

Main Results:

  • The best-performing ML model achieved 0.80 precision and 0.81 AUC on the test set.
  • Demonstrated robust classification performance without overfitting.
  • Feature importance analysis guided questionnaire design for practical application.

Conclusions:

  • ML models can effectively leverage public health databases for periodontitis evaluation.
  • The developed tool can overcome dental care access barriers by providing home-based predictions.
  • This AI-driven approach facilitates early detection and personalized dental care suggestions via smartphones or laptops.
