1. Influence of resin-modified glass ionomer and topical fluoride on levels of Streptococcus mutans in saliva and biofilm adjacent to metallic brackets
Abstract Decalcification of enamel during fixed orthodontic appliance treatment remains a problem. White spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. The use of fluoride-containing orthodontic materials has shown inconclusive results on their ability to reduce decalcification. The aims of this investigation were to co

2. CO2 laser and/or fluoride enamel treatment against in situ/ex vivo erosive challenge
ABSTRACT Objective This in situ/ex vivo study investigated the effect of CO2 laser irradiation and acidulated phosphate fluoride gel (APF) application, separately and in combination, on enamel resistance to erosion. Material and Methods During 2 experimental 5-day crossover phases, 8 volunteers wore intraoral appliances containing bovine enamel blocks wh

3. Fluoride rinse effect on retention of CaF2 formed on enamel/dentine by fluoride application
Abstract Calcium fluoride-like materials (“CaF2”) formed on dental surfaces after professional fluoride application are unstable in the oral environment but can be retained longer with a daily NaF mouthrinse. We tested the effect of twice daily 0.05% NaF rinses on the retention of “CaF2” formed on enamel and dentine after applying acidulated phosphat

4. Corrosion behavior of zirconia in acidulated phosphate fluoride
ABSTRACT Objective The corrosion behavior of zirconia in acidulated phosphate fluoride (APF) representing acidic environments and fluoride treatments was studied. Material and Methods Zirconia rods were immersed in 1.23% and 0.123% APF solutions and maintained at 37°C for determined periods of time. Surfaces of all specimens were imaged using digital mi

5. Delayed tooth replantation: MTA as root canal filling
MTA has been investigated as a root-end filling material. Its mechanism of action has some similarities to that of Ca(OH)2. The purpose of this study was to evaluate the repair process taking place in the delayed replantation of monkey teeth using calcium hydroxide and MTA as root canal filling materials. Five monkeys had their lateral incisors extracted and

6. Salivary retention after application of fluoride gel using toothbrush or tray: a crossover trial
Currently, there are no studies in the literature evaluating salivary fluoride retention after small amounts of fluoride gel are applied to children's teeth. Therefore, the objective of the present study was to compare salivary retention after gel application using a toothbrush or by traditional application with trays. In this crossover study, children with

7. Efeito do tempo de aplicação profissional de flúor fosfato acidulado em gel na desmineralização do esmalte de dentes decíduos e permanentes / Effect of application time of acidulated phosphate fluoride on demineralization of deciduous and permanent enamel
Embora o efeito de flúor fosfato acidulado em gel (FFA-gel) na redução da cárie dental em dentes permanentes esteja baseado em evidência, prévio estudo in situ realizado sob baixo desafio cariogênico sugere que a aplicação profissional de FFA-gel por 4 minutos não promove maior resistência a desmineralização ao esmalte permanente do que 1 minuto

8. Cariostatic effect of fluoride-containing restorative materials associated with fluoride gels on root dentin
Secondary caries is still the main cause of restoration replacement, especially on the root surface OBJECTIVE: This in vitro study evaluated the cariostatic effects of fluoride-containing restorative materials associated with fluoride gels, on root dentin. MATERIALS AND METHODS: A randomized complete block design was used to test the effects of the restorati

9. Effect of different topical fluoride applications on the surface roughness of a colored compomer
OBJECTIVE: The aim of this study was to evaluate the effect of neutral sodium fluoride (NNaF) gel and acidulated phosphate fluoride (APF) gel on the surface roughness of colored compomer (Twinky Star), conventional compomer (Compoglass F) and resin-modified glass-ionomer cement (RMGIC) (Photac-Fil). MATERIAL AND METHODS: A total of 45 standardized disc-shape

10. Surface degradation of glass ceramics after exposure to acidulated phosphate fluoride
OBJECTIVE: This study evaluated the surface degradation effect of acidulated phosphate fluoride (APF) gel exposure on the glassy matrix ceramics as a function of time. MATERIAL AND METHODS: Disc-shaped ceramic specimens (N = 120, 10/per ceramic material) were prepared in stainless steel molds (inner diameter: 5 mm, height: 2 mm) using 6 dental ceramics: 3 in

11. Avaliação de diferentes parâmetros para irradiação do esmalte dental com o laser de CO2 visando a redução da desmineralização / Evaluation of different CO2 laser parameters for inhibiting enamel demineralization in vitro
Although CO2 laser irradiation can decrease enamel demineralization, thermal damages to the surface are common side effects. The occurrence of fissures and cracks may compromise an in vivo application. Therefore, the aim of the present study was to find CO2 laser (?= 10.6 ?m) parameters resulting in maximum caries preventive effect with the lowest thermal da

12. Evaluation of the influence of the accelerated artificial aging and storage in 1.23% acidulated phosphate fluoride over superficial roughness and color stability of two low-fusing dental ceramics to commercially pure titanium / Avaliação da influência do envelhecimento artificial acelerado e armazenamento em fluorfosfato acidulado a 1,23% na rugosidade superficial e na alteração de cor de cerâmicas odontológicas de ultra-baixa fusão para titânio comercialmente pur
The purpose of this study was to evaluate the influence of accelerated artificial aging and of 1.23% acidulated phosphate fluoride over superficial roughness and color stability of two low-fusing dental ceramics for titanium (Triceram- Dentaurum, and Noritake Ti22- Noritake), metal-free or metalceramics using commercially pure titanium (Tritan- Dentaurum). 8
