13. 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

14. 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

15. Corrosion in Haas expanders with and without use of an antimicrobial agent: an in situ study
OBJECTIVES: The purpose of this study was to evaluate in situ the occurrence of corrosion in the soldering point areas between the wire, silver brazing and band in Haas expanders. MATERIAL AND METHODS: Thirty-four 7-12-year-old patients who needed maxillary expansion with a Haas expander were randomly assigned to two groups of 17 individuals each, according

16. 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

17. Timing of fluoride toothpaste use and enamel-dentin demineralization
It is well established that fluoride (F) prevents caries development by inhibiting demineralization and enhancing remineralization processes. However, it is not known which of these protective mechanisms is more important. In this double-blind, crossover in situ study conducted in three phases of 14 days each, 12 volunteers wore palatal appliances containing

18. Effect of different frequencies of fluoride dentifrice and mouthrinse administration : an in situ study
The effect of a combination of topical fluoridation methods for inhibition of enamel demineralization in the face of a cariogenic challenge has not been clearly established. This in situ crossover study aimed to assess whether the addition of daily use of fluoride mouthrinse (FR) to that of fluoride dentifrice (FD) is equivalent to increasing the frequency o

19. Efeito de sistema adesivo e dentifrÃcio fluoretados no desenvolvimento de cÃrie ao redor de restauraÃÃes com e sem fenda marginal em esmalte e dentina: estudo in situ / IN SITU EFFECT OF FLUORIDE FROM ADHESIVE SYSTEM AND DENTIFRICE ON CARIES FORMATION AROUND RESTORATIONS WITH GAP IN ENAMEL AND DENTINE
CÃries secundÃrias podem desenvolver-se na interface dente-restauraÃÃo diante da presenÃa de fendas marginais, mas este processo poderia ser inibido pela presenÃa de flÃor. Esta pesquisa teve como objetivo avaliar, in situ, atravÃs de um delineamento cruzado, aleatorizado, boca dividida e duplo-cego, a influÃncia do flÃor proveniente de sistema ade

21. A novel bioactive glass-ceramic for treating dentin hypersensitivity
Dentin hypersensitivity (DH) is a painful response to stimulus applied to the open dentinal tubules of a vital tooth. It's a common oral condition, however, without an ideal treatment available yet. This work evaluated in vitro the effect of micron-sized particles from a novel bioactive glass-ceramic (Biosilicate) in occluding open dentinal tubules. A dentin

22. pH-cycling models for in vitro evaluation of the efficacy of fluoridated dentifrices for caries control: strengths and limitations
Despite a plethora of in situ studies and clinical trials evaluating the efficacy of fluoridated dentifrices on caries control, in vitro pH cycling models are still broadly used because they mimic the dynamics of mineral loss and gain involved in caries formation. This paper critically reviews the current literature on existing pH-cycling models for the in v

23. Effect of different treatment methods for reducing morning bad breath. A randomized crossover clinical trial. / Avaliação clínica em estudo cruzado e randomizado de diferentes métodos para a redução da halitose matinal
The aim of this study was to compare the chemical effect of antimicrobial agents in mouthrinses and mechanical effect of tongue scrapers along with toothbrushing and dentifrice for conventional oral hygiene, measured by a handheld sulphide monitor BreathAlert™. Twenty healthy volunteers, from 18 to 50 years-old (the mean age was 35,9 years-old), of eit

24. Fingernail may not be a reliable biomarker of fluoride body burden from dentifrice
As unhas têm sido consideradas um biomarcador para a exposição ao flúor (F), mas não há consenso se é um indicador confiável para exposição ao F a partir do dentifrício. Vinte e três crianças, com idade entre 1 a 3 anos, moradoras de Piracicaba (0,72 ppm F na água), Brasil, foram submetidas a duas fases de diferentes exposição ao F: fase A (1
