Summary
A new classification system for gingival recession, using interproximal attachment loss, reliably predicts root coverage outcomes. This method offers a valuable tool for assessing and forecasting treatment results in periodontics.
Area of Science:
- Periodontology
- Dental diagnostics
- Regenerative dentistry
Background:
- Gingival recession presents diagnostic challenges.
- Predicting root coverage outcomes is crucial for treatment planning.
- A reliable classification system for gingival recession is needed.
Purpose of the Study:
- To test the reliability of a new gingival recession classification system.
- To evaluate the predictive value of this classification on root coverage outcomes.
Main Methods:
- A novel classification system based on interproximal clinical attachment loss was developed.
- Three recession types (RT1, RT2, RT3) were defined.
- Inter-rater and intra-rater reliability were assessed.
- Root coverage outcomes were evaluated at 6 months.
Main Results:
- The classification system demonstrated high inter-rater agreement (ICC=0.86).
- The RT classification was a significant predictor of final root coverage (p<0.0001).
- 116 gingival recessions in 25 patients were analyzed.
Conclusions:
- Interproximal clinical attachment level is a reliable criterion for classifying gingival recession defects.
- This classification system can predict final root coverage outcomes effectively.
