2. A new technique for tongue brushing and halitosis reduction: the X technique
Abstract The tongue is one of the primary sources of halitosis. The manual or mechanical removal of biofilm is known to decrease oral malodor. Objective: To evaluate a new tongue hygiene technique hereby referred to as “the X technique” and its effects on both halitosis and the number of microorganisms based on microbiological parameters and diagnostic

3. Effect of different artificial aging protocolson fluorescence of resin composites
ABSTRACT This study evaluated the effect of different artificial aging on fluorescence of resin composites. Forty-five cylindrical specimens (6mm in diameter and 1mm thick) were made of each resin composite: IPS Empress Direct, Filtek™ Z350 XT, and Durafill. A baseline measurement of fluorescence by the direct method using the fluorescence spectrophotomete

4. The Effect of Propolis in Healing Injured Nasal Mucosa: An Experimental Study
Abstract Introduction Mechanical trauma to the nasal mucosa increases the risk of synechia formation, especially after chronic rhinosinusitis and nasal surgeries. Objective This study was carried to assess the effect of propolis administration in healing injured nasal mucosa in rats. Methods We randomly divided eighteen rats into three equal experiment

5. Color stability and surface roughness of artificial teeth brushed with an experimental Ricinus communis toothpaste
Abstract Aim: To evaluate, in vitro, the effect of brushing with a Ricinus communis-based experimental toothpaste on color stability and surface roughness of artificial teeth. Methods: Ninety artificial teeth (maxillary central incisors) in different shades, light and dark (NatusDent Triple Pressing, Dentbras) were used. Initial color (Spectrophotometer

7. Use of dentifrices to prevent erosive tooth wear: harmful or helpful?
Dental erosion is the loss of dental hard tissues caused by non-bacterial acids. Due to acid contact, the tooth surface becomes softened and more prone to abrasion from toothbrushing. Dentifrices containing different active agents may be helpful in allowing rehardening or in increasing surface resistance to further acidic or mechanical impacts. However, dent

9. Effectiveness of mechanical brushing with different denture cleansing agents in reducing in vitro Candida albicans biofilm viability
A adesão de Candida albicans às superfícies é o primeiro passo para o desenvolvimento da estomatite protética, uma infecção frequente diagnosticada entre os usuários de próteses. Uma adequada higienização é essencial para prevenir a formação de biofilme microbiano e o início desta infecção. O objetivo deste estudo foi avaliar a efetividade d

10. The effectiveness of chemical denture cleansers and ultrasonic device in biofilm removal from complete dentures
Adequate denture hygiene can prevent and treat infection in edentulous patients. They are usually elderly and have difficulty for brushing their teeth. OBJECTIVE: This study evaluated the efficacy of complete denture biofilm removal using chemical (alkaline peroxide-effervescent tablets), mechanical (ultrasonic) and combined (association of the effervescent

11. Influencia da termociclagem, escovação mecanica e desinfecção quimica na dureza Knoop e rugosidade de superficie de resinas acrilicas com diferentes ciclos de polimerização / Influence of thermocycling, mechanical brushing and chemical disinfection on the Knoop hardness and surface roughness of acrylic resins with different cycles of polymerization
Este trabalho avaliou o efeito da termociclagem, escovação mecânica e desinfecção química na dureza e rugosidade de resinas com diferentes ciclos de polimerização. Foram confeccionadas 480 amostras (25 mm x 14 mm x 3 mm) e distribuídas aleatoriamente em 3 grupos de acordo com as resinas: Onda Cryl (G1), QC-20 (G2) e Clássico (G3). Metade das amostr

12. Effect of chemical degradation followed by toothbrushing on the surface roughness of restorative composites
OBJECTIVES: The aim of the present study was to assess the effect of the exposure to food-simulating liquids prior to brushing simulation on the surface roughness of five composite materials (Quixfil, Filtek Supreme, Esthet-X, Filtek Z250, Tetric Ceram). Material and METHODS: Twenty cylinders (5 mm diameter and 4 mm height) of each composite were randomly al
