25. Impact of filler size and distribution on roughness and wear of composite resin after simulated toothbrushing
OBJECTIVES: Nanofilled composite resins are claimed to provide superior mechanical properties compared with microhybrid resins. Thus, the aim of this study was to compare nanofilled with microhybrid composite resins. The null hypothesis was that the size and the distribution of fillers do not influence the mechanical properties of surface roughness and wear

26. Validation of the anti-bacteremic efficacy of an essential oil rinse in a Brazilian population: a cross-over study
This cross-over study was conducted to assess the germ-killing efficacy of an essential oil mouthrinse (EOM) by determining the blood levels of microorganisms associated with induced bacteremia and investigating the prevalence of this event in Brazilians with mild-to-moderate gingivitis. Thirty four (31.19%) subjects positive for bacteremia induced by chewin

28. Anticaries effect of dentifrices with calcium citrate and sodium trimetaphosphate
Because of the growing concerns regarding fluoride ingestion by young children and dental fluorosis, it is necessary to develop new dentifrices. OBJECTIVE: The aim of this study was to evaluate the effect of dentifrices with calcium citrate (Cacit) and sodium trimetaphosphate (TMP) on enamel demineralization. MATERIAL AND METHODS: Enamel blocks (n=70), previ

31. Efeito do fosfopeptídeo de caseína-fosfato de cálcio amorfo (cpp-acp) no controle da erosão do esmalte dentário.
O objetivo deste estudo foi avaliar o efeito do CPP-ACP no controle da erosão dentária. Para isso foram realizados dois estudos 1 e 2. (1) O objetivo do estudo 1 foi avaliar in vitro o efeito de pastas contendo CPP-ACP e dentifrícios fluoretados no controle da erosão dentária associada ou não à abrasão. Oitenta blocos de esmalte foram distribuídos e

32. Efeito do laser de CO2 associado ao dentifrício fluoretado na prevenção de cárie de superfície oclusal : um estudo in situ / Effects of CO2 laser combined with fluoridated dentifrice on the prevention of occlusal surface : an in situ study
O declínio na prevalência de cárie tem sido acompanhado por uma alteração no padrão dessa doença, com um aumento da prevalência na superfície oclusal quando comparada às superfícies lisas. Apesar do amplo uso do fluoreto, o seu efeito na prevenção da cárie dental é parcial. A utilização do laser de CO2 e de tratamentos com flúor têm sido c

33. In situ anticariogenic effect of conventional glass ionomer cement by dentrifice dependence / Efeito anticariogênico de cimento de ionômero de vidro convencional pela dependência de dentrifício: estudo "in situ"
The aim of this study was to assess in situ anticaries potential of conventional glass ionomer cement (GIC) to prevent enamel and dentine demineralization either alone or in combination with a fluoride (F) regimen. A randomized, blind, crossover design for caries induction was carried out in 2 phases of 14 days each. This study was a 2 x 2 cross-over factori

34. Effect of vegetable oil (Brazil nut oil) and mineral oil (liquid petrolatum) on dental biofilm control
Dental biofilm control represents a basic procedure to prevent caries and the occurrence of periodontal diseases. Currently, toothbrushes and dentifrices are used almost universally, and the employment of good oral hygiene allows for appropriate biofilm removal by both mechanical and chemical control. The aim of this study was to evaluate the effectiveness o

36. Combination effect of fluoride dentifrices and varnish on deciduous enamel demineralization
The aim of this study was to evaluate the anticaries potential of 500 or 1100 ppm F dentifrices combined with fluoride varnish using a pH-cycling regimen. Seventy primary canines were covered with nail polish, leaving a 4×4 mm window on their buccal surface, and randomly assigned into 7 groups (n = 10): S: sound enamel not submitted to the pH-cycling regime
