Colour stability of relined dentures after chemical disinfection. A randomised clinical trial

Abstract

Colour stability of the denture materials is one variable to be considered when choosing disinfection methods. The data in this study will be useful to clinicians when they are selecting disinfectant solutions for disinfection of relined denture.

Effect of Different Chemical Disinfectants on Color Stability of Acrylic Denture Teeth

“…Table shows the spectrophotometric measurement steps for the eight experimental groups, the labeling of the obtained L*a*b* values, and the measurement steps and labeling of the ΔE values. The obtained ΔE* values have been quantified by National Bureau of Standards (NBS) units to match the color differences for the clinical conditions (NBS units‐clinically acceptable level <3.0) . The NBS units were calculated with the formula: All measurements were performed under the D65 type illuminant with a 10° observation angle.…”

“…Besides denture base materials, studies also report color changes in relined dentures, maxillofacial elastomers, and artificial irises after immersion in chemical disinfectants . However, there are sparse data about the color stability of denture teeth.…”

The Effect of Different Techniques of Microwave Disinfectionon Elastomeric Impression Materials (Laboratory and Microbiological Study)

“…However, glutaraldehyde induces inhalation toxicity and eye irritation, sodium hypochlorite induces the bleaching of dental materials, and povidone iodine induces loss of pigmentation. (4,5) Microwave ovens are simple to use, low in cost and can provide disinfection effect. (6) The disinfection of dentures with microwave irradiation has been attempted and has been found to be better than the use of sodium hypochlorite.…”

In vitro effects of Salvia officinalis L. essential oil on Candida albicans

“…effective denture-cleansing agents. However, discoloration of the dentures and even damage to the prosthesis have been reported after routine immersion of dentures in these solutions [4,5] . The search of new therapeutic alternatives has revealed that herbal extracts have potential antimicrobial actions.…”
