What this trial studies

This clinical trial is a randomized triple-blind study that compares the effectiveness of two periodontal techniques for root coverage: the tunneling technique with connective tissue grafts and the coronal advancement flap technique. Participants with specific types of gingival recession will undergo one of the two procedures, and their clinical, aesthetic, and patient perception outcomes will be evaluated. Follow-up assessments will measure root coverage, keratinized tissue gain, and other relevant parameters, while also analyzing the morbidity associated with each technique. The goal is to provide insights that will help oral health professionals choose the most effective treatment for gingival recessions.

Who should consider this trial

Good fit: Ideal candidates are non-smoking individuals with specific types of gingival recession and no systemic diseases or active periodontal disease.

Not a fit: Patients with systemic diseases, active periodontal disease, or advanced gingival recession may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help improve treatment outcomes for patients with gingival recession, leading to better oral health and aesthetics.

How similar studies have performed: Other studies have shown success with similar periodontal techniques, indicating potential for positive outcomes in this trial.
