Clinical and patient-centred long-term results of root coverage using the envelope technique in a private practice setting: 10-year results-A case series.

AIM: Evaluation of long-term results after connective tissue graft (CTG) using the envelope technique and the effect on patient-centred outcomes (Oral Health Impact Profile: OHIP) in a private practice setting. MATERIALS AND METHODS: Fifteen patients (11 female, mean age: 45.0 ± 8.88 years) underwent root coverage procedure using a CTG involving maxillary Miller class I teeth. Pre-operatively, 3 and 120 ± 12 months after surgery, all patients were examined, completed OHIP questionnaire, and were asked to assess improvement and their satisfaction with the results of surgery. All procedures were performed by the same investigator. RESULTS: Recession depth at 3 months of 1.19 ± 0.93 mm was reduced to that of 0.63 ± 0.64 mm at 120 ± 12 months after surgery (p = .117). Recession width (-1.23 ± 2.27 mm) decreased as well (p = .117), while relative root coverage increased from 48.46 ± 32.18% at 3 months to 71.22 ± 30.86% at 120 months (p = .011). The number of cases with complete root coverage increased from two (15.4%) to six (40.0%) from 3 to 120 months (p = .046). OHIP score (12.07 ± 10.15) did not change after 10 years (12.13 ± 9.86, p = .889). Ten years after surgery, 12 patients (80%) reported they would make the decision again to undergo CTG transplantation. CONCLUSIONS: Within the limitations of the study design with a high risk of bias in a practice setting, long-term stability of recession reduction, OHIP and patient-perceived satisfaction remained stable over 10 years.

Effect of root coverage on oral health impact profile (g49): a pilot study.

Purpose. The aim of this prospective longitudinal clinical pilot study was the evaluation of the effect on the Oral Health Impact Profile (OHIP) and patient-centered results of the envelope technique for Connective Tissue Graft (CTG). Methods. Sixteen patients (11 females) 24 to 71 years of age (42.6 +/- 11.1) received CTG that had been harvested from the palate and grafted using the envelope technique. Prior to and 3 months after surgery, all patients were examined clinically, completed the OHIP-G49 questionnaire, and were asked to judge the results of surgery. Results. Mean baseline recession depth of 2.5 +/- 0.8 mm was reduced by 1.2 +/- 0.9 mm (P < .001). Root coverage amounted to 48 +/- 39%. In 5 of 16 defects complete root coverage was achieved. Pain at the donor site was more pronounced than at recipient site regarding prevalence (8/6; P = .007), intensity (2.1 +/- 2.3/1.1 +/- 1.9 [visual analogue scale]; P = .016), and duration (1.4 +/- 2.3/0.8 +/- 1.4 days; P = .042). Baseline OHIP (15.7 +/- 12.1) was decreased by 3.6 +/- 8.5 three months after surgery (P = .139). Thirteen patients (81%) would undergo CTG surgery for similar reasons again. Conclusions. Root coverage using CTG according to the envelope technique provided improvement of OHIP as early as 3 months after surgery. Over all, patients were reasonably satisfied with the surgical technique and its results.
