Uso de vernizes fluoretados na avaliação do índice sangramento gengival em crianças: estudo in vivo

Resumo (EN)

Objective – The purpose of this study was to evaluate the therapeutic effect of two different fluoride varnishes and the presence of gingival bleeding. Methods – The sample consisted of 28 students of both genders, 8-12 years old of a public school from a city without fluoride water. The codes and criteria used for caries diagnosis were SB BRASIL (2003) and gingival bleeding index (GBI). The children were divided in two groups: G1 (n = 13) Duraphat® and G2 (n = 15) Clinpro®. Before applying the varnishes, the gingival bleeding index (GBI) was recorded, prophylactic performed with prophylactic paste and then varnishes applied in three sessions followed at weekly intervals. The examination was accomplished by one examiner, previously calibrated. The level of significance was set at 95% (CI). Results – The mean dmft index was 1.8 (± 2.0) and DMFT was 2.6 (± 2.3). There was a decrease of GBI times 7, 14 and 21 days, although lower for G1 than for G2. The reduction was greater in G2 (p<0.05). Conclusion – Thus, both fluoride varnishes studied caused gingival bleeding reduction over time.
