Clinical Evaluation of Single-stage Advanced Versus Rotated Flaps in the Treatment of Gingival Recessions

• Status: Completed
• Trial end date: 2011-12-01
• Target enrollment: 0
• Participant gender: All

Summary

BACKGROUND: Several procedures have been reported for the surgical correction of gingival recession (GR), including the laterally positioned flap (LPF) and the coronally advanced flap (CAF), performed as single or two-stage procedures without or with, respectively, the preceding placement and healing of a free gingival graft (FGG). The objective of the present report was to compare the efficacy of single-stage LPF and CAF techniques in the treatment of localized maxillary GR defects.

METHODS: Thirty-six patients with Miller class I GR defects were randomly assigned to be treated by either a CAF (n=18) or LPF (n=18). Clinical parameters, including recession height (RECH), the width of keratinized tissue (WKT), probing depth (PD) and vertical clinical attachment level (VAL) were assessed at the mid-buccal site. Visual plaque score (VPS) and bleeding on probing (BOP) were also assessed dichotomously. Clinical recordings were performed at baseline, 6 months and 5 years later. Inter-measurements differences were analyzed with a Chi-square or a Wilcoxon test, with significance set at α<0.05.

Criteria

Inclusion Criteria:

• Adult patients with no contraindications for periodontal surgery, and who had not taken medications known to interfere with periodontal tissue health or healing in the preceding 6 months, exhibiting the presence of Miller class I gingival recessions5 in maxillary incisors, canines or premolars, probing depth (PD) <3mm without bleeding on probing, presenting tooth vitality and absence of caries or restorations in the areas to be treated.

Exclusion Criteria:

• Patients with untreated periodontal disease, smokers, subjects with immunosuppressive systemic diseases (i.e., cancer, AIDS, diabetes) were not included in the study.

• Miller class II, III or class IV recession defects5, presence of apical radiolucency or caries or restorations in the areas to be treated, and previous lack of cooperation with the maintenance program were also exclusion criteria.
