Minimally invasive gingival phenotype modification in gingival recession associated with a non-carious cervical lesion using the root plastique technique (RPT): A quasi experimental one-group pretest-posttest study.

BACKGROUND
This study introduced the root plastique technique (RPT), the aim of which is to modify the gingival phenotype of sites with gingival recessions (GRs) associated with Non-Carious Cervical Lesions (NCCLs) prior to surgical treatment.


METHODS
RPT was performed in 22 subjects with 53 RT1 A/B + GRs. Changes in keratinized tissue thickness (KTT), keratinized tissue width (KTW), relative gingival recession (RGR), relative clinical attachment level (RCAL) and probing pocket depth (PPD) were measured at baseline (T0) and 2 months (T1) after the procedure was performed. All analyses were performed by means of hierarchical models.


RESULTS
The study revealed statistically significant changes (p<0.01) in KTT (0.45 ± 0.04 mm), RGR (0.80 ± 0.13mm), KTW (0.67 ± 0.07mm), RCAL (-0.72 ± 0.16mm) and KTW (0.67 ± 0.07). No changes in PPD (p>0.05) were observed. Regression analyses of KTT increase and RGR reduction at T0 showed statistically significant correlation between the 2 variables (p<0.05). All the teeth with a KTT of <0.8mm at T0 (N = 14) reached or surpassed this threshold at T1.


CONCLUSION
RPT increases KTT and KTW. In most of the sites, a reduction in GR was also achieved. This article is protected by copyright. All rights reserved.
