ABSTRACT
OBJECTIVE: This study evaluated the efficacy of NitrAdineTM-based disinfecting cleaning tablets for complete denture, in terms of denture biofilm removal and antimicrobial action. MATERIAL AND METHODS: Forty complete denture wearers (14 men and 26 women) with a mean age of 62.3±9.0 years were randomly assigned to two groups and were instructed to clean their dentures according to two methods: brushing (control) - 3 times a day with denture brush and tap water following meals; brushing and immersion (Experimental) - brushing the denture 3 times a day with denture brush and tap water following meals and immersion of the denture in NitrAdineTM-based denture tablets (Medical InterporousTM). Each method was used for 21 days. Denture biofilm was disclosed by a 1 percent neutral red solution and quantified by means of digital photos taken from the internal surface before and after the use of the product. Microbiological assessment was conducted to quantify Candida sp. RESULTS: An independent t-test revealed a significant lower biofilm percentage for the experimental group (4.7, 95 percent CI 2.4 to 7.9) in comparison with the control group (mean 37.5, 95 percent CI 28.2 to 48.1) (t38=7.996, p<0.001). A significant reduction of yeast colony forming units could be found after treatment with Medical InterporousTM denture tablets as compared to the control group (Mann-Whitney test, Z=1.90; p<0.05). CONCLUSION: The present findings suggest that NitrAdineTM-based disinfecting cleaning tablets are efficient in removal of denture biofilm. In addition, a clear antimicrobial action was demonstrated. Therefore, they should be recommended as a routine denture maintenance method for the prevention of the development of microbial biofilm induced denture stomatitis.

A remontagem é um procedimento que busca o restabelecimento da dimensão vertical de oclusão e da relação oclusal das próteses totais, modificadas por alterações dimensionais dos materiais de inclusão, das técnicas de prensagem e do comportamento dimensional da resina acn1ica durante a polimerização. Diferentes técnicas podem ser utilizadas, tentando minimizar tais alterações, o que pode causar controvérsias em relação a esse passo. Este trabalho busca realizar uma revisão sobre a técnica de remontagem em prótese total apresentando os diversos fatores envolvidos.
