Abstract

Background. A shallow vestibule, insufficient keratinized tissue width and pulling of marginal gingiva may be associated with gingival recession, plaque accumulation and gingivitis. Conventional techniques for treatment of gingival recession use autogenous or allogenic grafts. However, these methods result in soreness at the donor site and pose an economic burden, which may cause patients to withdraw from treatment. Alternative therapy is currently not available to treat such patients.
Objectives. The aim of this study was to evaluate changes in periodontal tissue at the mandibular incisors after vestibuloplasty, focusing on functional improvement of the existing soft tissue with no grafting.
Material and Methods. Thirty patients with a shallow vestibule, minimal keratinized tissue width (KTW; ≤1 mm), gingival recession (REC) and pulling of gingiva underwent modified Kazanjian vestibuloplasty were included into the test group, whereas 27 patients did not undergo any surgery (control group). The probing pocket depth (PPD), clinical attachment level (CAL), gingival recession depth (GRD), and KTW were assessed at baseline and 12 months post-surgery.
Results. The mean KTW, GRD and CAL values improved in the test group. A significant increase in mean KTW value (1.17 ±1.22 mm, p = 0.0406) was detected in the test group, while the control group showed a further reduction in mean KTW value (0.13 ±0.45 mm). The mean GRD value decreased from 2.09 ±1.78 mm to 1.22 ±1.46 mm (p = 0.0087) in the test group, whereas in controls the mean GRD value increased from 1.95 ±1.29 mm to 2.34 ±1.44 mm (p = 0.0164). The mean KTW value at 3, 6 and 12 months compared to baseline showed an increase in the test group, and the mean GRD and CAL values exhibited the potential to improve.
Conclusion. Sites treated with vestibuloplasty showed increased KTW, improvement in the gingival margin and CAL gain, whereas untreated sites showed continuous deterioration of the evaluated parameters. Vestibuloplasty may be recommended for patients avoiding major surgery for which functional improvement in tissue alone would provide a sufficient therapeutic outcome.
