1. Effect of new innovative restorative carbomised glass cement on intrapulpal temperature rise: an ex-vivo study
Abstract This study aimed to evaluate the temperature changes that occurred in the pulp chamber when using GCP Glass Carbomer Fill (GCP) and two different resin-modified glass-ionomer (RGI) restorative materials at different dentin thicknesses. A standardized Class I occlusal cavity with 1 mm or 2 mm dentin thickness was prepared in the extracted human molar

2. Evaluation of temperature increase during in-office bleaching
ABSTRACT The use of light sources in the bleaching process reduces the time required and promotes satisfactory results. However, these light sources can cause an increase in the pulp temperature. Objective The purpose of the present study was to measure the increase in intrapulpal temperature induced by different light-activated bleaching procedures with a

3. Ex-vivo evaluation of the intrapulpal temperature variation and fracture strength in teeth subjected to different external bleaching protocols
Este estudo avaliou a influência de protocolos de clareamento na temperatura intrapulpar e resistência à fratura de dentes clareados. Noventa incisivos superiores foram divididos em 9 grupos (n=10): G1: peróxido de carbamida a 35% (PC 35%), G2: peróxido de hidrogênio a 38% (PH 38%), G3: luz halógena, G4: LED-laser, G5: PC 35% + luz halógena, G6: PH 3

4. Intrapulpal temperature variation during bleaching with various activation mechanisms
OBJECTIVES: The aim of this study was to evaluate the intrapulpal temperature variation after bleaching treatment with 35% hydrogen peroxide using different sources of activation. MATERIAL AND METHODS: Twenty-four human teeth were sectioned in the mesiodistal direction providing 48 specimens, and were divided into 4 groups (n=12): (G1) Control - Bleaching ge

5. Pulpal temperature increase with high-speed handpiece, Er:YAG laser and ultrasound tips
The aim of this study was to compare intrapulpal temperature increase produced by high-speed handpiece, Er:YAG laser and CVDentus ultrasound tips during cavity preparation. Thirty bovine mandibular incisors with an enamel/dentin thickness of 4 mm at buccal surface had their roots amputated and were allocated to the following groups (n=10): Group I- high-spee

6. Intrapupal temperature variation during Er,Cr: YSGG enamel irradiation on carries prevention
Studies have shown the cariostatic effect of Er,Cr:YSGG (2.78 mm) laser irradiation on human enamel and have suggested its use on caries prevention. However there are still no reports on the intrapulpal temperature increase during enamel irradiation using parameters for caries prevention. The aim of this in vitro study was to evaluate the temperature variati

7. Estudo in vitro da resistência à desmineralização e da retenção de flúor em esmalte dental irradiado com laser de Er, Cr: YSGG / IN VITRO STUDY OF DEMINERALIZATION RESISTANCE AND FLUORIDE RETENTION IN DENTAL ENAMEL IRRADIATED WITH Er,Cr: YSGG LASER
This study aimed to stablish irradiation conditions of Er,Cr:YSGG laser (wavelength of 2.79 µm) which could propitiate changes on human dental enamel and increase its resistance to demineralization, when associated or not with topical application of acidulated phosphate fluoride (APF). Fluences of 2,8 J/cm², 5,6 J/cm² e 8,5 J/cm² were selected;

8. Determination of safe parameters of the CO2 laser ( lambda =10,6 mu m) and its association with fluoridated products on dental enamel demineralization progression : in vitro estudies / Determinação de parametros de segurança e da associação do laser de CO2 ( lambda =10,6 mu m) a composto fluoretados na progressão da desmineralização do esmalte dentario : estudos in vitro
The irradiation of dental enamel by CO2 laser, especialIy if combined with fluoride, can increase the enamel acid resistance. Thus, this thesis, comprised by 2 manuscripts, aimed: to establish the lowest energy fluency of a pulsed 10.6 Ilm C02 laser that, when applied on enamel surface, is able to cause chemical and morphological changes and reduces its acid

9. In vitro and in vivo appraisal of pre-heated resin composite with relation to polymerization kinetics / "Avaliação in vitro e in vivo da resina composta pré-aquecida em relação à cinética de polimerização
This work examined multiple aspects of pre-heating dental resin composite prior to light-curing: the monomer conversion and polymerization kinetics as a function of cure temperature, light-exposure duration and depth; the performance of the heating device (maximum temperature, thermal stability of device and temperature change when pre-heating compules); and
