13. Effect of toothbrushing with different manual toothbrushes on the shear bond strength of orthodontic brackets
The aim of this study was to evaluate the effect of brushing with a Colgate 360º or Oral B Indicator 35 toothbrush on the shear bond strength of orthodontic brackets bonded to extracted human teeth. The bristle wear and bristle tip morphology were also examined after simulated tooth-brushing. Orthodontic brackets (Roth-P/1st and 2nd premolar S/D- Slot 0.18"

14. Antimicrobial agents used in the control of periodontal biofilms: effective adjuncts to mechanical plaque control?
The control of biofilm accumulation on teeth has been the cornerstone of periodontal disease prevention for decades. However, the widespread prevalence of gingivitis suggests the inefficiency of self-performed mechanical plaque control in preventing gingival inflammation. This is particularly relevant in light of recent evidence suggesting that long standing

15. ANALYSIS OF SURFACE ROUGHNESS OF THE HUMAN ENAMEL EXPOSED OR NOT THE ACTION OF BLEACHING AGENT AFTER BRUSHING WITH DIFFERENT DENTIFRICES / ANÁLISE DA RUGOSIDADE SUPERFICIAL DO ESMALTE HUMANO EXPOSTO OU NÃO À AÇÃO DE AGENTE CLAREADOR APÓS ESCOVAÇÃO COM DIFERENTES DENTIFRÍCIOS
The aim this study was to evaluate, in vitro, the average surface roughness (Ra) of human enamel exposed or not to the action of bleaching agent with carbamide peroxide (CP) 10% after brushing with different dentifrices. Ninety-six (96) specimen enamel was used and divided into two groups: GI- exposed to the action of bleaching agent and GII- non exposed to

16. Influence of resin-composite formulation on the intra-oral degradation : in vitro study / Influencia da formulação de resinas compostas na resistencia a degradação intra-oral : estudo in vitro
Natural teeth, as well as restorations, are composed of materials that are subject to deterioration. Besides chemical, mechanical and thermo degradation, the formulation and post-cure composites network are dominant mechanism to determine the restorations longevity. The purpose of this study was to investigate the effect of materials formulation, light

17. Clinical evaluation of the efficacy on biofilm removal from complete denture of the chemical (alkaline peroxide) and mecanical (ultrasonic) methods / Avaliação clínica da eficácia dos métodos químico (peróxido alcalino) e mecânico (ultra-som) frente à propriedade de remoção do biofilme de próteses totais
The aim of this study was to evaluate the hability of the biofilm removal from complete denture of the chemical (alkaline peroxide-effervescent tablets to complete denture immersion), mechanical (ultrasonic) and combined (association of the effervescent and ultrasonical methods) methods. Eighty patients that use upper and lower complete denture participated

18. Efeito da escovação mecanica e da termociclagem sobre dureza e rugosidade superficiais de reembasadores resilientes / Effect of mechanical brushing and ageing by thermal cycling on hardness and roughness surface of resilient soft liners
The aim of this study was to evaluate the effect of mechanical brushing and thermocycling on hardness and roughness of three resilient definitive lining materials: 1) auto (Sofreliner MS), 2) heat-polymerized (Molloplast-B) silicone bases; and 3) auto-polymerized plasticized acrylic resin (Dentuflex). To prepare the samples, silicone rubber matrixes were mad

19. Efeito da escovação mecanica e de agentes quimicos de limpeza de proteses sobre as caracteristicas superficiais de materiais reembasadores resilientes
The aim of this study was to evaluate the influence of mechanical brushing and denture cleansers on the surface properties of soft lining materials. Three soft liners, Luci Sof (Dentsply), Molloplast-B (Dentax), and Sofreliner (Tokuyama), two denture cleansers Efferdent (Warner-Lamber Co- EUA), and 0,5% alkaline hypochlorite preparation, the Reach Profession

20. Coadjuvants of buccal hygiene in dog feeding / Coadjuvantes de higiene bucal na alimentaÃÃo de cÃes
Although, veterinary dentistry is a relatively new specialization, the dental disease is one of the most common problems affecting pets. Among the affections attacking the buccal cavity the most prevalent is the periodontal disease, whose determinant factor is the bacterial plate. From the 1990, products which have received in their formulation minerals inhi

21. Avaliação da clorexidina no controle do biofilme dental em crianças portadoras de necessidades especiais
Disabled children show difficulties to perform the mechanical control of dental plaque and show a high prevalence of periodontal disease. In this group of patients, the association between chemical agents and dental brushing runs into an exact indication of use and chlorhexidine is the best suited agent for this purpose. Therefore, this research main objecti

22. Resin cements wear resistance evaluation under brushing abrasion preceded by pH cycling simulations / Resistência ao desgate de cimentos resinosos submetidos à ciclagem de pH e escovação simulada
Indirect aesthetic restorations have been found to have a wide variation on its adaptation, subjecting consequently, the luting material to the oral environment degradation provided by physical, mechanical or chemical processes. Thus, theirwear resistances still worry researchers. In this context, the objective of this work was to evaluate the wear resistanc

23. Efeito da ação de diferentes escovas, na manutenção das caracteristicas superficiais de reembasadores resilientes submetidos a escovação mecanica
The aim ofthis study was to evaluate "in vitro" the effect ofbrushing on the surface features of resilient lining materiaIs. TIrirty samples were prepared and divided into 6 groups of variables with 5 test repetitions for each variable. The samples were made with acrylic matrixes placed in a flask to obtain a cast pressed molel, later filled with resilient l

24. Specific thermal responsiveness of ventromedial hypothalamic neurons to localized scrotal heating and cooling in rats.
1. The specificity of thermoresponsive ventromedial hypothalamic (VMH) neurons to localized, incremental scrotal thermal cooling and heating of urethane-anaesthetized male Sprague-Dawley rats (maintained at 37 degrees C colonically) was investigated. 2. Ventromedial hypothalamic extracellular neuronal activity and surface (scalp) electroencephalogram (EEG) a
