LIMA, Jadson Almeida et al. Changes in the subgingival biofilm composition after coronally positioned flap. J. Appl. Oral Sci. [online]. 2011, vol.19, n.1, pp.68-73. ISSN 1678-7757.

OBJECTIVES: This study evaluated the effects of coronally positioned flap (CPF) on the subgingival biofilm composition. MATERIAL AND METHODS: Twenty-two subjects with gingival recessions were treated with CPF. Clinical parameters were assessed before and at 6 months after surgery. Subgingival biofilms were analyzed by checkerboard DNA-DNA hybridization technique for 40 bacterial species. RESULTS: Recession height, clinical attachment level and bleeding on probing improved significantly (p<0.05) at 6 months post-CPF. The proportions of 10 periodontal pathogens and the proportions of red and orange complexes decreased at 6 months. CONCLUSION: In conclusion, CPF can induce beneficial effects on the composition of the subgingival microbiota after 6 months.
