1. Polymicrobial Leakage and Retention of MTA and Portland Cement in a Model of Apexification
Abstract Objective: To evaluate the sealing capacity and retention of apical barriers made with mineral trioxide aggregate (MTA) and Portland cement (PC). Material and Methods: Fifty-six bovine incisors were sectioned 8 mm above and 12 mm below the cement-enamel junction. The root canal was enlarged with a diamond drill to create a standard 2.5 mm diameter

2. Influence of cigarette smoke combined with different toothpastes on enamel erosion
Abstract: This in vitro study aimed to evaluate the effect of different toothpastes on dental enamel subjected to an erosive cycle with and without exposure to cigarette smoke. Bovine enamel specimens were randomly allocated into 12 groups (n = 12). For the in vitro simulation of smoking, half the groups underwent an exposure cycle of 20 cigarettes per day f

4. In Situ Effect of Intra-Oral Application of Pastes Containing CPP-ACP or CPP-ACPF Against Initial Enamel Erosion
Abstract Objective: To evaluate in situ the effect of toothpastes containing casein phosphopeptide - amorphous calcium phosphate (CPP-ACP) and casein phosphopeptide-amorphous calcium phosphate associated to fluoride (CPP-ACPF) on initial erosion prevention. Material and Methods: Bovine enamel blocks (n = 192) were randomly assigned into 4 phases according

5. Quantitative image of fluorescence of ceramic and resin-cement veneers
Abstract The main of the study was quantify the effect of two ceramics with two underlying resin cements on apparent fluorescence levels. Buccal surfaces of two bovine incisors were ground flat producing one enamel and one dentin substrate. The veneers were fabricated (0.5 and 1.0 mm thickness) using two ceramics (IPSe.max Press and IPSe.max Zirpress, Ivocla

6. 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

7. In Vitro Evaluation of Fluoride in Saliva After Topical Application of Professional Use Products
Abstract Objective: To evaluate in vitro the presence of fluoride in saliva after applying professional use products on the surface of dental enamel. Material and Methods: Experimental groups were composed by: Cariostatic 12% (CA), Fluoridated Varnish 5% (FV), Fluorine Acidulate Gel 1.23% (AG) and Fluorine Neutral Gel 2% (NG). Fluoridated dentifrice (FD) a

9. Remineralizing effect of commercial fluoride varnishes on artificial enamel lesions
Abstract: The aim of this study was to evaluate soluble and insoluble fluoride concentrations in commercial varnishes, and their remineralization effect on artificial caries enamel lesions using surface and cross-sectional microhardness evaluations. Forty bovine enamel blocks were separated into four groups (n=10): control (no treatment), Enamelast (Ultraden

10. Effect of iontophoresis on fluoride uptake in enamel with artificial caries lesion
Abstract: Iontophoresis is a noninvasive technique, based on the application of a constant low-intensity electric current to facilitate the release of a variety of drugs, whether ionized or not, through biological membranes. The objective of this research was to evaluate the effect of iontophoresis using different electric current intensities on the uptake o

11. Effect of a resin-modified glass-ionomer with calcium on enamel demineralization inhibition: an in vitro study
Abstract We assessed the effect of a new coating material based on resin-modified glass-ionomer with calcium (Ca) in inhibiting the demineralization of underlying and adjacent areas surrounding caries-like lesions in enamel. The measures used were surface hardness (SH) and cross-sectional hardness (CSH). Thirty-six bovine enamel specimens (3 × 6 × 2 mm) we

12. Structural Organization of Dental Biofilm Formed in situ in the Presence of Sucrose Associated to Maltodextrin
Resumo Maltodextrinas, derivadas do amido de milho, tem sido adicionadas a alimentos industrializados combinadas à sacarose. Entretanto não estão esclarecidas as propriedades de difusão na matriz do biofilme dental e a estrutura tridimensional de biofilmes multiespécies formados na presença destes carboidratos. Portanto o objetivo deste estudo foi aval
