Resumo
Objective: The aim of this study was to evaluate the infl uence of periodontal clinical
parameters on the treatment of gingival recession by means of a coronally positioned
fl ap (CPF).
Materials and methods: In this clinical study, the coronally positioned fl ap technique
was used in a sample of 14 individuals with Miller’s Class I or II gingival recession of
the canines and/or maxillary premolars, totaling 39 recessions. The clinical periodontal
parameters evaluated were: probing depth (PD), gingival recession height (GRH), gingival
recession width (GRW), clinical attachment level (CAL), keratinized mucosa (KM), attached keratinized mucosa (AKM), gingival thickness (GT) and free gingival margin
thickness (GMT). The degree of root coverage was evaluated 3 months after the surgical
procedures were performed. The data were analyzed using Student’s-t, Mann-Whitney
and Pearson’s correlation tests, as well as the Cohen’s d.
Results: After root coverage, there was no signifi cant change in PD. Signifi cant reductions in GRH and GRW were observed. In addition, a signifi cant reduction in KM and
AKM, and an increase in GMT were also observed. A signifi cant negative correlation
was found between initial GMT and gingival recession at 3 months, and a signifi cant
negative correlation between GT and periodontal recession at 3 months. There was large
effect size for GRH, GRW, CAL, KM, AKM and GMT parameters.
Conclusions: The initial gingival recession height, keratinized mucosa and free gingival
margin thickness were the parameters that had the most infl uence on root coverage by
the coronal sliding fl ap technique
