Influence of Periodontal Parameters on Root Coverage: A Longitudinal Study

Area of Science:

• Periodontology
• Regenerative Dentistry

Background:

• Periodontal recession affects tooth aesthetics and sensitivity.
• Surgical interventions aim to restore lost gingival tissue.

Purpose of the Study:

• To assess how initial periodontal parameters influence the success of coronally positioned flap (CPF) surgery for treating gingival recession.
• To identify key predictors of root coverage after CPF procedures.

Main Methods:

• The coronally positioned flap (CPF) technique was applied to 39 Miller Class I/II recessions.
• Evaluated parameters included probing depth, recession dimensions, keratinized mucosa, and flap thickness.
• Root coverage was assessed at 6 months and 1 year post-surgery.

Main Results:

• Significant reductions in recession height/width and increases in keratinized mucosa were observed.
• Initial recession dimensions and flap thickness negatively correlated with root coverage percentage at 1 year.
• Gingival recession and flap thickness were significant predictors of root coverage.

Conclusions:

• Initial gingival recession dimensions and mucosa thickness are linked to root coverage outcomes.
• Gingival recession width emerged as the primary predictor for successful root coverage.
