چکیده
|
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.
