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.

2013 July;61(4):36.
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.

Treatment of oral malodor and periodontal disease using an antibiotic rinse
Ken Southward, DDS, FAGD
Anne Bosy, RDH, MEd, MSc
2013 July;61(4):41.
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.
