Efetividade a longo prazo de métodos de escovação para remoção de placa bacteriana de molares em erupção

Abstract

The aim of this study was to assess the long-term effectiveness of the end-tufted toothbrushes and conventional toothbrush using transversal technique in the removal of the bacterial plaque on occlusal surfaces of erupting permanent first molars. Fifty two teeth were selected from children aged 5 years and 6 months to 7 years and 6 months, divided into 2 groups randomly. These had at least one first permanent molar partially erupted and met the inclusion and exclusion criteria. The previous plaque mapping procedures were performed with basic fucsina applied to the occlusal surface of the teeth of interest for the research. Individuals in group 1 (group of toothbrushes) were instructed to use these brushes in a manner similar to a "broom", sweeping the occlusal surface from the inside out. Those who were part of group II (group of conventional toothbrushes associated with the transverse technique) were instructed to perform brushing horizontally in the buccolingual direction. Research participants underwent 4 assessments, an initial assessment, one after counseling, one week, one month after. At each visit, the patients were reassessed using the plaque mapping procedure. There was no statistically significant difference between the transverse and end-tufted toothbrushes groups (p> 0.05) at each time analyzed. Both techniques of brushing were effective in the long term. The brushing technique with the end-tufted toothbrushes brusher presented a more enduring result when in stratified analysis. It was concluded that although there was no superiority of one technique over the other, it is necessary to obtain a larger sample and a longer time of follow-up of the cases for more definitive results.
