RIVERA, S.; YEVENES, I.; REYES, J.  e  NORERO, H.. Comparative effect again mouthrinses-gel of chlorhexidine with commercial mouthrinses in the growth of plaque in 24 hours. Avances en Periodoncia [online]. 2006, vol.18, n.3, pp.163-169. ISSN 2340-3209.

The chlorhexidine solutions (CHX) standars in prevention of plaque formation present some undesired effects like the pain by alcohol. The aim of this study was to determine the clinical effectiveness of Colutoriogel^® (new formulation) of chlorhexidine to the 0,1% and to compare with mouthrinses to the 0,12% and 0,1% with alcohol being evaluated growth of bacterial plaque. In double-blind, randomised, cross-over study, 25 young dental students with a healthy periodontium, abolished all means of mechanical plaque control during 4 experimental periods of 1 day (separated from each other by a washout period of 4 weeks). During each experimental period, they rinsed 1 daily with one of the following mouthrinses in a randomised order: CHX 0,12% + alcohol (Oralgene ^®), CHX 0,12% + alcohol (Perio.Aid^®), CHX 0,1%+ alcohol (Dentilim^®) and CHX 0,1% + HMC 2,5% (Colutoriogel^®). After 1 days of undisturbed plaque formation, clinical parameters were recorded and questionnaires completed. The CHX 0,12% + alcohol and the and CHX 0,1% + HMC 2,5% formulations were efficient in retarding de novo plaque formation (proven by clinical observations data), and always superior (p<0,05) to the CHX 0,1%+ alcohol (Dentilim^®) solution. Conclusions. The results of this study demonstrated the potential of a new mouthrinses-gel Colutoriogel^®) nonalcoholic formulation as an effective anti-plaque agent with reduced unpleasant subjective side-effects.
