Summary

Increased tooth mobility in dogs reduced periodontal tissue resistance to probing. Alterations like bone loss and collagen reduction were observed in mobile teeth, impacting clinical assessments.

Area of Science:

  • Periodontology
  • Biomedical Engineering

Background:

  • Tooth mobility can affect periodontal tissue health.
  • Accurate clinical probing is essential for diagnosing periodontal disease.

Purpose of the Study:

  • To investigate how increased tooth mobility influences periodontal tissue resistance to probing.
  • To identify specific tissue alterations associated with mobile teeth.

Main Methods:

  • Inducing controlled tooth mobility in beagle dogs using a jiggling device on premolars.
  • Conducting clinical examinations and mobility measurements over 3 months.
  • Harvesting biopsies for histometric and morphometric analysis of periodontal tissues.

Main Results:

  • Mobile teeth exhibited reduced resistance to periodontal probing.
  • Histometric analysis revealed decreased alveolar bone height and collagen content in mobile teeth.
  • Enlarged supracrestal connective tissue with increased vascularity was observed in mobile teeth.

Conclusions:

  • Tooth mobility leads to significant periodontal tissue alterations.
  • These alterations compromise the reliability of clinical probing in assessing periodontal status.
