Clinical and antimicrobial efficacy of NitrAdine ™-based disinfecting cleaning tablets in complete denture wearers.

Objective: This study evaluated the efficacy of NitrAdine ™-based disinfecting cleaning tablets for complete denture, in terms of denture biofilm removal and antimicrobial action.

Material And Methods: Forty complete denture wearers (14 men and 26 women) with a mean age of 62.3 ± 9.

Evaluation of the efficacy of chemical disinfectants for disinfection of heat-polymerised acrylic resin.

Objective: This study evaluated the efficacy of disinfectants on the internal aspect of heat-polymerised acrylic resin contaminated with microbial strains.

Background: Dentures absorb oral fluids and become contaminated by different microorganisms.

Methods: Two hundred and fifty rectangular specimens were made of heat-polymerised acrylic resin, and then divided into five groups corresponding to the microbial strains (Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, S.

In vitro antimicrobial activity of irreversible hydrocolloid impressions against 12 oral microorganisms.

This study evaluated in vitro the antimicrobial activity of irreversible hydrocolloids (one containing an antimicrobial agent) prepared with water or with a 0.2% chlorhexidine digluconate solution against 12 strains of the oral microbiota. Twenty specimens (0.

Bacterial, fungal and yeast contamination in six brands of irreversible hydrocolloid impression materials.

This study assessed the level of contamination of six commercially available irreversible hydrocolloids (two containing chlorhexidine) and identified the contamination present in the materials. Petri dishes containing selective and enriched culture media were inoculated with alginate powder (0.06 g), in triplicate.

[Biofilm disclosing agents in complete denture: clinical and antimicrobial evaluation].

This study evaluated the disclosing ability, removal facility and antimicrobial effect of biofilm disclosing agents applied on complete dentures. Disclosing ability was evaluated by means of the visual method. The solutions were applied on the internal surface of dentures.
