Clinical and patient‐centered outcomes using two types of subepithelial connective tissue grafts: A split‐mouth randomized clinical trial

Abstract

Background

This split‐mouth randomized clinical trial compared two different types of subepithelial connective tissue grafts (SCTG) considering clinical parameters and patient‐centered outcomes in patients with bilateral RT 1 multiple gingival recessions after 6 months postoperatively.

Methods

21 patients were surgically treated with coronally advanced flap (CAF) associated with SCTG harvested by: double blade scalpel (DBS) and de‐epithelized (DE) SCTG. Periodontal clinical parameters and aesthetics were evaluated by a calibrated periodontist at baseline and after 6 months. Patient‐centered outcomes related to pain/discomfort and aesthetics were assessed with Visual Analogue Scale (VAS) after 7 days and 6 months, respectively.

Results

All clinical parameters, with the exception of PD, demonstrated differences in intra‐group evaluation, comparing baseline to 6‐month evaluation (p<0.05). Both groups presented reduction of RD and RW and gain of KTT, KTW and CAL (p<0.05). Intergroup comparison (DBS X DE) demonstrated no significant differences considering clinical parameters and periods. Both techniques improved aesthetics evaluated by patients, without difference between groups in patients and professional analysis. However, DBS group presented inferior pain/discomfort compared to DE (p<0.05).

Conclusion

DBS and DE associated with CAF presented satisfactory clinical outcomes. However, DBS presented inferior morbidity, an important fact for decision‐making process. ClinicalTrials.gov #NCT04093674
