Chlorhexidine & ultrasonics
The aim of the present pilot randomized clinical trial was to
evaluate the effects of ultrasonic mechanical instrumentation (UMI)
associated with the professional use of chlorhexidine (CHX)
formulations compared with UMI alone during periodontal supportive
therapy in patients with generalized aggressive periodontis (G-AgP).
Test group received a single session of UMI associated with
subgingival irrigation under cavitation with CHX 0.02%. A 0.2% CHX
solution was used for professional tongue brushing and mouthrinsing.
The control group received a similar session of UMI associated with
subgingival irrigation and professional tongue brushing and
mouthrinsing with a control formulation. Clinical and
microbiological parameters were assessed pre-treatment at 3, 6 and
12 weeks post-treatment.
UMI either with or without additional CHX use determined a
significant reduction of supragingival plaque and gingival
inflammation as well as a significant reduction of subgingival
bacterial pathogens. The additional use of CHX did not result in any
additional clinical and microbiological benefit with respect to mere
UMI.
