 This study compared the microbicidal effect of 2% glutaraldehyde and 0.2% peracetic acid for the disinfection of dental impressions made with vinyl polysiloxane, using 2 methods: immersion and ultrasonic nebulization. The results indicate that ultrasonic nebulization is an effective microbicidal method for polyvinylsiloxane impressions when either solution was used.

 This case report describes the restoration of a central incisor that was previously restored with an unesthetic three-quarter gold crown. A CAD/CAM three-quarter crown was planned to conserve tooth structure. After preparation, the tooth was scanned for a CAD/CAM crown in order to fabricate a ceramic restoration, which was then milled and bonded, producing an esthetic result.

 The study’s goal was to determine the effectiveness of an antibiotic rinse preparation, containing metronidazole and nystatin, in decreasing oral malodor and periodontal disease for individuals whose chief complaint was halitosis. The results indicated a substantial decrease in both halitosis and periodontal disease markers, which was accomplished without the risk of the systemic effects of an oral antibiotic.

 This study evaluate the efficacy of a mouthrinse containing 0.3% chlorine dioxide in reducing oral volatile sulfur compounds (VSCs). The VSC reduction rate of the test mouthrinse was superior to a placebo and a 0.07% cetylpyridinium chloride solution. There was no difference between the test mouthrinse and a 0.2% chlorhexidine gluconate solution in VSC reduction rates.

 This article reviews the case of a 66-year-old man who developed an elevated international normalized ratio and sustained clinically significant bleeding as a result of a drug-drug interaction between warfarin and amoxicillin. An objective causality assessment revealed that this adverse drug event, secondary to the warfarin and amoxicillin interaction, was probable.
