Objectives
The aim of this study is to compare wound healing and patient pain perception of single-incision (single-incision, modified single-incision) and trap-door surgical techniques to harvest subepithelial connective tissue grafts from the palate.
Material and methods
Thirty-six patients were selected for root coverage procedures with subepithelial connective tissue grafts and randomly assigned to two single-incision groups or a trap-door group (n = 12/group). One week after surgery, a modified early-wound healing index (EHI), patient pain and painkiller intake were recorded. Follow-up was performed until complete epithelialization was achieved.
Results
Single-incision techniques showed significantly improved early healing over trap-door approaches. Specifically, the mean EHI was 2.50 ± 1.14 for single-incision techniques, as compared to 3.33 ± 1.30 for trap door. The incidence of secondary healing was significantly lower in the single-incision groups. Concomitantly, the cumulative dosage and duration of painkiller intake were significantly reduced, as compared to the trap-door group.
Conclusion
Within the limits of this trial, single-incision techniques can lead to improved early healing and reduced patient pain after subepithelial connective tissue graft harvesting than trap-door techniques.
Clinical relevance
Avoiding trap-door incisions for harvesting of connective tissue grafts may reduce patient morbidity.
