Practical denture disinfection

Dental laboratory personel are at risk of contracting infections from dental prostheses that have not been properly disinfected. A 4% chlorhexidine scrub for 15 seconds followed by a 3-minute contact time with a chlorine dioxide solution was effective in disinfecting contaminated dentures. Chair-side disinfection of dental prostheses before laboratory procedures is the key to keeping microbial contamination out of the dental laboratory.

Effect of tinfoil substitute contamination on adhesion of resin denture tooth to its denture base

At least one manufacturer claims that contamination of denture teeth with tinfoil substitute during processing is not detrimental. The purpose of this study was to determine whether tinfoil substitute contamination has any significant effect on the bond strength between acrylic resin denture teeth and their processed acrylic resin base. Eighty acrylic resin maxillary central incisors were processed to denture base material. The experimental group had the denture tooth ridgelap area contaminated with tinfoil substitute. The control group was not contaminated. The bond strength of the two groups was tested. The results indicate that contamination with tinfoil substitute significantly reduces the bond strength of acrylic resin denture teeth bonded to their denture base.

The effect of a surface disinfectant on a dental cast

This study determined the effect of a disinfectant solution on dental casts. Stone samples were immersed in a disinfectant solution and in control solutions. The results indicate that a saturated calcium sulfate (clear slurry) solution with 0.525% sodium hypochlorite was an effective disinfectant and acted without damage to the dental cast.

Removable prosthodontic laboratory survey

This article presents a brief review of the literature concerning the curriculum deemphasis for removable prosthodontics, especially on the subject of complete dentures. The authors surveyed commercial dental laboratories specializing in removable dental prosthetics in three major Texas cities to determine whether dentists were submitting adequate records and information with their complete denture work authorizations. Results indicate that dentists are requesting services from their laboratories without providing adequate records.

Technique for ☐ing an altered cast impression

Abstract An alternate method is presented for laboratory management of altered cast impressions. This technique provides a quick, reliable method that reduces the possibility of laboratory mismanagement. It is also an alternate to techniques by Bolouri et al. 2 and McCracken. 3
