Abstract

The present randomized clinical trial aimed to evaluate the effect of povidone iodine associated with single session full-mouth ultrasonic debridement as treatment forgeneralized aggressive periodontitis. Twenty eight patients presenting generalized aggressive periodontitis were followed during 6 months. Inclusion criteria was restricted to patients under35 five years old, with at least eight tooth with probing depth (PD) ? 5 mm and bleeding on probing (BOP), from which at least two tooth had to present PS ? 7 mm. The patients were randomly alocated in one of the evaluated groups: DB + saline solution (n=14) - single session full-mouth ultrasonic debridement with 0.9% saline solution as cooling agent, and DB + iodine (n=14) - single session full-mouth ultrasonic debridement with 10% povidone iodine solution as cooling agent. Clinical and immunological parameters were evaluated at baseline, 1st, 3rd and 6th month after treatment. Both therapies reduced plaque index and BOP, promoted PD reductions, relative clinical attachment level gains and recession in the position of gingival margin (PGM) at the end of the study. Both therapies promoted reduction in interleukin 1? levels and increase of interleukin 10 levels at the end of the study. However, during the period of the study, the differences were not statistically significant among the two groups regarding the clinical and the immunological parameters. Therefore, it can be concluded that the association of povidone iodine with 45 minute single session full-mouth ultrasonic debridement protocol did not promote additional benefits regarding the evaluated clinical and immunological parameters when compared to the same ultrasonic protocol associated with saline solution.
