To preserve oral health and to maintain the prosthetic devices, it is important not only improve properties of commonly known hygiene products, but also investigate new materials with antimicrobial action. Objectives This study evaluated activity sodium hypochlorite (0.25% 0.50%) 10% Ricinus communis' solutions against specific microorganisms. Material Methods Sixty four maxillary complete denture wearers were instructed brush their dentures three times a day soak them (20 min/day) in...

The aim of this study was to evaluate the effect three denture hygiene methods against different microbial biofilms formed on acrylic resin specimens.The set (sterile stainless steel basket and specimens) contaminated (37 degrees C for 48 hours) by a inoculum with 10(6) colony-forming units (CFU)/ml (standard strains: Staphylococcus aureus, Streptococcus mutans, Escherichia coli, Candida albicans, Pseudomonas aeruginosa, Enterococcus faecalis; field S. C. glabrata, tropicalis). After...

Adequate denture hygiene can prevent and treat infection in edentulous patients. They are usually elderly have difficulty for brushing their teeth. OBJECTIVE: This study evaluated the efficacy of complete biofilm removal using chemical (alkaline peroxide-effervescent tablets), mechanical (ultrasonic) combined (association effervescent ultrasonic) methods. MATERIAL AND METHODS: Eighty wearers participated experiment 21 days. were distributed into 4 groups (n=20): (1) Brushing with water...

Abstract Purpose: Adequate denture hygiene can prevent and treat infection in edentulous patients, who are frequently elderly have difficulty brushing their teeth. This study evaluated the efficacy of complete biofilm removal using a chlorhexidine solution two concentrations: 0.12% 2.0%. Materials Methods: Sixty wearers participated trial for 21 days after receiving instructions. They were distributed into three groups, according to tested regimen (n = 20): (G1) Control (daily overnight...

The development of opportunistic infections due to poor denture hygiene conditions justified the search for effective protocols controlling biofilm. Objective This study evaluated Ricinus communis and sodium hypochlorite solutions in terms biofilm removal ability, remission candidiasis, antimicrobial activity, participant satisfaction. Material Methods It was conducted a controlled clinical trial, randomized, double-blind, crossover. Sixty-four wearers with (n=24) without candidiasis (n=40)...

This study evaluated colour stability, surface roughness and flexural strength of microwave-polymerised acrylic resin after overnight immersion in sodium hypochlorite, simulating 180 days use.Forty disc-shaped (15 mm x 4 mm) 40 rectangular specimens (65 10 3 were prepared from resin. The immersed 0.5, 1% Clorox/Calgon distilled water. Colour measurements (ΔE) determined by a portable colorimeter. A analyser was used to measure (μm). (MPa) measured using three-point bending test universal...

Objectives: The purpose of this study was to evaluate biofilm distribution over internal and external surfaces upper complete dentures. It also aimed at assessing the effect oral hygiene instructions before after home use a disclosing solution. Materials methods: sample consisted 29 denture wearers whose prostheses were evaluated. Surface disclosed by means 1% neutral red solution quantified with regard surfaces. Oral information provided on an individual basis. During second stage, amount...

doi: 10.1111/j.1741-2358.2010.00378.x Effervescent tablets and ultrasonic devices against Candida mutans streptococci in denture biofilm Objective: To evaluate the antimicrobial action of effervescent ultrasound on spp. from biofilm. Background: It is not uncommon for edentulous patients to be elderly find it difficult brush their dentures. Hence, auxiliary methods are required cleansing dentures as well treating oral infections. Materials methods: Seventy-seven complete wearers were...

doi: 10.1111/j.1741‐2358.2011.00503.x Oral health related quality of life edentulous patients after denture relining with a silicone‐based soft liner Background: Knowledge benefits caused by treatment on is very relevant. Despite the wide use and acceptance liners, it necessary to evaluate patient’s response about these materials regard improvement in oral (OHRQoL). Objectives: The aim this study was influence OHRQoL patients. Materials methods: Thirty‐two complete wearers had their lower...

Complete denture fabrication involves a series of complex technical procedures. Nevertheless, simplified methods may be as effective conventional ones albeit the lesser use time and resources, without disadvantage for patient. This study compared method complete to protocol in terms oral health-related quality life (OHRQoL), patient satisfaction quality. Forty-two edentulous patients requesting treatment with dentures were randomly allocated into two groups. Group S received fabricated by C...

This study evaluated Knoop hardness, surface roughness and color alteration of artificial teeth for dentures after immersion in water, 1% sodium hypochlorite an experimental solution 2% Ricinus communis (RC).
