Summary
Periodontal probing offers a simple and reliable method for assessing gingival biotype. This technique aligns well with cone-beam CT measurements, proving effective for clinical use.
Area of Science:
- Periodontology
- Dental Diagnostics
Background:
- Gingival biotype assessment is crucial in periodontology.
- Existing methods may lack convenience or objectivity.
Purpose of the Study:
- To develop a simple, objective, and applicable method for gingival biotype assessment.
- To validate periodontal probing as a diagnostic tool for gingival thickness.
Main Methods:
- Evaluated gingival biotypes using periodontal probing clarity.
- Measured gingival thickness at the cemento-enamel junction (CEJ) via cone-beam CT (CBCT).
- Recruited 14 volunteers (66 teeth) with healthy gingiva (ages 20-30).
Main Results:
- Periodontal probing demonstrated good consistency and repeatability for gingival biotype assessment.
- Probing results correlated well with CBCT measurements.
- Significant differences in mean gingival thickness were observed across thin (1.02±0.20 mm), compromised (1.28±0.25 mm), and thick (1.46±0.25 mm) biotypes (P=0.001).
Conclusions:
- Periodontal probing provides a simple, objective, and suitable method for clinical gingival biotype examination.
- This technique offers a practical alternative for routine dental assessments.
