Summary

The aim of the study is to compare the effect of a suspension containing Triclosan in dynamic of the subgingival biofilm formation versus a Placebo suspension. The initial subgingival biofilm formation will be evaluated by means of Plaque Free Zone (PFZ).

Detailed description

This is a double blind, cross over, randomized clinical trial. 28 volunteers will stop mechanical supragingiva biofilm removal measures for 96h following a complete scaling and polishing of the tooth surfaces. During this period they will be asked to rinse for one minute with a slurry of either a triclosan containing dentifice or a control without triclosan. Every 24h the presence of deposits will be registered with special atention to the presence of a plaque free zone between the apical border of the deposits and the gingival margin. Absence of deposits is scored 0, presence of deposits and plaque free zone =1 and presence of deposits and absence of plaque free zone =2 (MALISKA, A. N. et al. Measuring early plaque formation clinically. Oral health preventive dentistry, v. 4, p. 273-278, 2006). The prevalence of scores and the rate of changes from scores 0 and 1 into 2 will be evaluated for significance. Sample size was calculated taking the results from the study o MALISKA, AN (2006) as reference.

Interventions

Type	Name	Description
OTHER	Test - Using of a suspension containing Triclosan	The participants should have used only the suspension containing Triclosan during 5 days and have stopped with their biofilm control homemade procedures.
OTHER	Control - Using of a suspension without Triclosan	The participants should have used only the Placebo suspension during 5 days and have stopped with their biofilm control homemade procedures.
