RESUMO
BACKGROUND: Although many Authors have reported the use of root surface biomodification (RSB), the clinical outcomes in terms of root coverage are still unclear, as a number of biomodifier agents have been used in combination with various periodontal plastic surgical techniques. In this review we aim to evaluate the efficacy of RSB in root coverage and its impact on the outcomes. METHODS: A search of MEDLINE and Cochrane databases was carried out along with 2 manual searches. A combination of specific terms was used to identify relevant studies that met well-defined inclusion and exclusion criteria. Clinical attachment level, probing depth and percentage root coverage after treatment were among the results expected to be reported in the included articles. RESULTS: A total of 10 articles were identified and data were extracted. Only 6 met the inclusion criteria. Among these 6 studies, citric acid, ethylenediaminetetraacetic acid and laser therapy were used as RSB agents and free gingival graft, subepithelial connective tissue graft plus coronally advanced flap and semilunar coronally respositioned flap were the surgical approaches to root coverage treatment. Baseline and outcome data were analyzed and compared. CONCLUSION: RSB provided no additional benefit in terms of the evaluated clinical parameters. Within the limitations of this review, we found no evidence to support the use of RSB prior to root coverage treatment.

Introdução: As cirurgias mucogengivais têm sido amplamente utilizadas para o tratamento de problemas periodontais. Nos casos de recobrimento radicular diversas são as técnicas utilizadas, dentre elas, o retalho posicionado lateralmente (RPL) e o enxerto de tecido conjuntivo subepitelial (ETCS). Objetivo: Apresentar um caso clínico de recobrimento radicular no qual foram utilizadas conjuntamente as técnicas de RPL e ETCS. Relato: Paciente procurou tratamento periodontal com queixa principal de sensibilidade dental. Foram observadas recessões classe I de Miller nos dentes 23, 24 e 25 e faixa de tecido queratinizado de 1 mm na região dos dentes em questão. A técnica escolhida para tratamento das recessões foi o enxerto de tecido conjuntivo associado ao retalho posicionado lateralmente. Resultados: Após 35 dias observou-se completa cobertura da superfície radicular e ganho de tecido queratinizado de 4 a 5 mm.
Introduction: Mucogingival surgeries have been widely used for the treatment of periodontal problems. In cases of root coverage many techniques are used, among them, the laterally positioned flap (LPF) and subepithelial connective tissue graft (SCTG). Objective: To present a clinical case of root coverage in which was used together the techniques of LPF and SCTG. Report: The patient sought for periodontal treatment complaining of tooth sensitivity. It was observed Miller Class I recessions on teeth 23, 24 and 25 and 1 mm of keratinized tissue track in the region of these teeth. The technique used for treatment of recessions was the connective tissue graft associated with the laterally positioned flap. Results: After 35 days was observed complete coverage of the root surface and keratinized tissue gain 4 to 5 mm.
