Microsurgical Versus Conventional Semilunar Coronally Advanced Flap

• Status: Completed
• Trial end date: 2012-04-01
• Target enrollment: 0
• Participant gender: All

Summary

BACKGROUND: The semilunar coronally repositioned flap (SLCRF) has been used for the treatment of recession defects (GR). Recently a microsusgical (MICRO) has been successfully employed with the procedure apparently resulting in improved results, however, no previous controlled clinical study has evaluated the MICRO SLCRF in comparison with SLCRF performed as originally described (MACRO). The objective of the present study was to compare the clinical outcomes of the MICRO and MACRO SLCRF in the treatment of human GR.

METHODS: Fourteen patients, with bilateral Miller class I GR defects were randomly assigned to MICRO or MACRO SLCRF. Clinical parameters, assessed at baseline and 6 months later, included recession height (RECH), recession width (RECW), width of keratinized tissue (WKT), probing depth (PD), clinical attachment level (CAL), pain measurements and esthetic evaluation with the Root Coverage Score (RCS). Inter-measurements differences were analyzed with a Chi-square or a paired t-test, with significance set at α<0.05.

Criteria

Inclusion Criteria:

• Presence of bilateral Miller class I gingival recessions (≤ 3mm) exhibiting at least 2mm of keratinized tissue width (WKT) in endodontically-vital maxillary canines or premolars.

• These teeth presented shallow (<3mm) probing depth (PD) without bleeding on probing. Moreover, the elegible individuals demonstrated absence of contraindications for periodontal surgery, and were not being taking medications known to interfere with periodontal tissue health or healing in the preceding 6 months.

• Experimental teeth were free 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 defects, presence of apical radiolucency or caries or restorations in the areas to be treated, and previous lack of cooperation with the maintenance program (as evaluated by unjustified absence from scheduled maintenance visits, continued traumatic tooth brushing technique or faulty plaque control measures).
