Despite it ́s efficacy in treating oral infections, dental and tongue staining associated with the use of chlorhexidine is one of the adverse which discourages it ́s long-term use the most. The aim of this study was to analyze the effect of a solution containing 0,12% chlorhexidine , 0,05% cetylpyridinium and 0,05% sodium fluoride on the anti-plaque activity and extrinsic dental and tongue staining. 48 dental students volunteered for the study, with a mean of 22,3 years of age. The design of the study was double-blind, randomized, placebo-controlled. The participants were allocated in 3 groups, and received the following solutions: Group I - solution containing 0,12% chlorhexidine , 0,05% cetylpyridinium and 0,05% sodium fluoride ( Noplak Max ® solution. In the 1st phase of the study the individuals were instructed to quit al oral hygiene measures for 24h, after receiving a prophylaxis and using 15ml of the allocated mouthwash for 1 min. After this period, the individuals had their teeth photographed with a digital camera, so that the area covered with plaque and evidenced with fucsine could be analyzed. During the 2nd phase , after a 1 week interval, the participants received another prophylaxis and the oral hygiene methods were quit for 3 days. During this period the volunteers were instructed to use the allocated mouthwash, under supervision, 8 times a day, for 1 min. Immediately after the volunteers also drank warm black tea (35°C) for 2 min. The area and intensity of the staining of the teeth and tongue were analyzed with the means of digital photography using an image editor software. The results of inhibitory plaque formation activity showed a difference in plaque covered area approximately 25% less in Group I and II than in Group III. Group I showed a higher number of areas free of staining, and a lower number of areas with light or moderate staining, when compared with the other groups ( p<0,05). Also the number of individuals with ); Group II – solution of chlorhexidine 0,12%; Group III – Placebo moderate, or moderate/intense staining, was smaller in Group I when compared with the other groups ( p< 0,05). None of the individuals in Group I showed intense dental or tongue staining, whereas 25% ( 4/16) of the individuals of Group II showed this type of dental staining, and 6% (1/16) of intense tongue staining. The results of this study showed that the tested solution ( Noplak Max ® formation inhibition, showing a higher percentage of staining-free surfaces, and a lower staining potential than the other solutions.
