Abstract

Objective: To evaluate the effectiveness of autogenous connective tissue grafting in combination with enamel matrix derivative (EMD) in the treatment of periodontitis with intrabony defects. Subjects and Methods: A pre–post clinical intervention study was conducted on patients diagnosed with stage III or IV periodontitis (according to the 2017 AAP classification) who had previously received non-surgical periodontal therapy. Eligible sites exhibited periodontal pocket depth ≥ 6 mm and intrabony` defects ≥ 3 mm. All patients underwent periodontal regenerative surgery using connective tissue grafting combined with EMD. Periodontal parameters were assessed at baseline and three months postoperatively, including probing pocket depth (PPD), clinical attachment level (CAL), gingival thickness, buccal gingival recession (RECb), interproximal gingival recession (RECi), full-mouth plaque score (FMPS), and full-mouth bleeding score (FMBS). Results and Conclusion: Within the limitations of this study, the connective tissue graft technique combined with EMD demonstrated effective periodontal tissue regeneration in subcrestal defects, while maintaining stable gingival height postoperatively.
