1. Comparative Effects of CPP-ACP and Xylitol F-Varnishes on the Reduction of Tooth Erosion and Its Progression
Resumo Avaliou-se o efeito dos vernizes CPP-ACP/NaF e xilitol/NaF na redução da erosão e progressão da erosão. Quarenta blocos de esmalte foram divididos em quatro grupos (n=10): G1=verniz CPP-ACP/NaF (verniz MITM); G2=verniz xilitol/NaF (Profluorid®); G3=verniz NaF (Duraphat®, controle positivo) e G4=água desionizada (MilliQ®, controle negativo).

5. The Impact of Radiotherapy in the in Vitro Remineralization of Demineralized Enamel
Abstract Objective: To evaluate the impact of radiotherapy on enamel around restorations of glass ionomer cement (GIC) and fluoride tooth paste (FTP). Material and Methods: Eighty enamel blocks were made and randomly distributed into two groups, according to the fluoride therapy, non-fluoride tooth paste (NFTP) and FTP (n=40) and in subgroups in conformity

6. The in vitro remineralizing effect of CPP-ACP and CPP-ACPF after 6 and 12 weeks on initial caries lesion
Abstract Objective: The aim of this in vitro study was to determine the effects of remineralization promoting agents containing casein phosphopeptide-stabilized amorphous calcium phosphate (CPP-ACP), or CPP-ACP in combination with fluoride (CPP-ACPF) on artificial white spot lesions (WSLs) after 6 and 12 weeks. Methodology: White spot lesions were created

7. Effect of erosive challenges on deciduous teeth undergoing restorative procedures with different adhesive protocols - an in vitro study
ABSTRACT Objective: To evaluate the effect of erosive challenges on the tooth- restoration interface of deciduous teeth treated with different adhesive protocols. Material and Methods: Deciduous molars were cut mesiodistally, then embedded, abraded and polished (n=80). Samples were randomly divided according to the adhesive system used into: G1 (Adper Sing

8. Thickness and nanomechanical properties of protective layer formed by TiF4 varnish on enamel after erosion
Abstract The layer formed by fluoride compounds on tooth surface is important to protect the underlying enamel from erosion. However, there is no investigation into the properties of protective layer formed by NaF and TiF4 varnishes on eroded enamel. This study aimed to evaluate the thickness, topography, nanohardness, and elastic modulus of the protective l

9. Color stability and surface roughness of artificial teeth brushed with an experimental Ricinus communis toothpaste
Abstract Aim: To evaluate, in vitro, the effect of brushing with a Ricinus communis-based experimental toothpaste on color stability and surface roughness of artificial teeth. Methods: Ninety artificial teeth (maxillary central incisors) in different shades, light and dark (NatusDent Triple Pressing, Dentbras) were used. Initial color (Spectrophotometer

10. One-year clinical evaluation of the retention of resin and glass ionomer sealants on permanent first molars in children
Abstract Aim : To compare the retention of glass ionomer cement (GIC) used as fissure sealant with a resinbased sealant. Methods: Six- to nine-year-old children (n=96) with all permanent first molars in occlusion were examined and assigned to two groups: GIC sealant or resin-based sealant. The sealants were applied according to the manufacturers' recommend

11. Effect of foods and drinks on primary tooth enamel after erosive challenge with hydrochloric acid
The aim of this study was to evaluate the effect of industrialised foods and drinks on primary tooth enamel previously eroded with hydrochloric acid (HCl). The crowns of one hundred two specimens were subjected to an erosive challenge with HCl and randomly divided into six groups (n = 17): Chocolate Milk (Toddynho® - Pepsico) - negative control; Petit Suiss

12. Filling of simulated lateral canals with gutta-percha or thermoplastic polymer by warm vertical compaction
The aim of this study was to evaluate the ability of gutta-percha and a thermoplastic synthetic polymer (Resilon) to fill simulated lateral canals, using warm vertical compaction. Forty-five single-rooted human teeth were prepared using the rotary crown-down technique. Artificial lateral canals were made at 2, 5, and 8 mm from the working length (WL) in each
