    Guided tissue regeneration (GTR) initially shows high root coverage, but results significantly decline long-term. Long-term stability of GTR for root coverage is questionable due to significant recession and attachment loss.

    Area of Science:

    • Periodontal regeneration
    • Tissue engineering in dentistry

    Background:

    • Root coverage is crucial for periodontal health.
    • Guided tissue regeneration (GTR) is a common technique for periodontal defects.

    Purpose of the Study:

    • To assess the long-term stability of root coverage achieved with GTR.
    • To evaluate changes in recession and attachment levels post-GTR.

    Main Methods:

    • Longitudinal study evaluating GTR for root coverage.
    • Measurements of root coverage, recession, and attachment levels taken at 6 months and final follow-up (mean 25.3 months).

    Main Results:

    • Mean root coverage was 92.3% at 6 months, decreasing to 58.8% at final follow-up.
    • Statistically significant increases in recession (1.4 mm) and attachment loss (1.7 mm) were observed between 6 months and final evaluation.

    Conclusions:

    • The results of GTR for root coverage may not be stable long-term.
    • Further research is needed to improve the durability of GTR outcomes in periodontal therapy.
