Effect of sodium hypochlorite and Ricinus communis solutions on control of denture biofilm: A randomized crossover clinical trial

Evaluation of biofilm removal and adverse effects on acrylic resin by diluted concentrations of sodium hypochlorite and Ricinus communis solutions

“…Badaró et al used 0.25% and 0.5% solutions, on participants with and without denture stomatitis, which indicated the lowest percentage of biofilm compared to a 10% R. communis solution. Concentrations of 0.1% and 0.2% were also effective on biofilm removal and antimicrobial action, when used in participants with denture stomatitis.…”

“…The patient has the responsibility to maintain good oral hygiene conditions, and the dentist must motivate and instruct the patient about denture and oral hygiene, guiding an effective biofilm control by appropriate methods; however, these steps are neglected . Combination of mechanical and chemical methods is the most significant method for denture hygiene owing to the ability to remove biofilm (mechanical method) and show antimicrobial action (chemical solution) …”

“…Literature has shown that sodium hypochlorite should be used in diluted concentrations and short time of immersions because such solutions may cause adverse effects depending on the concentration, time and period of immersion employed, which are directly related to the durability and success of the rehabilitation. Concentrations of 1% and 0.5% were effective in controlling denture biofilm and commonly used as a denture cleanser; however, these solutions showed alterations on the properties of the acrylic resin when evaluated, for short and long immersions, simulating a period of 6 months, 18 months, 5 years …”

“…The analyses of crude drug new formulations with an accessible cost and that do not lead damage to the denture materials are required. The Ricinus communis solution appears to be viable due its biocompatibility, powerful detergent action, anti‐inflammatory activity, bactericidal and fungicidal potential, and effectiveness on remission of denture stomatitis …”

Novas tendências de combate ao biofilme de Candida em próteses dentárias

“…Essa enfermidade possui etiologia multifatorial, sendo que a má higiene e o uso contínuo de próteses dentárias têm sido as causas mais frequentemente associadas a essa doença 2 . Apesar de C. albicans ser o microrganismo mais recorrentemente associado a EP, as espécies de C. não albicans (CNA) já foram isoladas das superfícies de dentaduras de pacientes com essa enfermidade 3,4 . As próteses dentárias proporcionam superfícies que facilitam a acumulação de biofilmes de placas ao longo do tempo.…”
