1. The use of a liner under different bulk-fill resin composites: 3D GAP formation analysis by x-ray microcomputed tomography
Abstract Gap formation of composite resin restorations is a serious shortcoming in clinical practice. Polymerization shrinkage stress exceeds the tooth-restoration bond strength, and it causes bacterial infiltration within gaps between cavity walls and the restorative material. Thus, an intermediate liner application with a low elastic modulus has been advis

2. Influence of Cavity Dimensions on Microleakage of Two Bulk-Fill Composite Resins
Abstract Objective: To evaluate the effect of cavity dimensions on the amount of microleakage in two different types of bulk-fill composite resins. Material and Methods: Forty class II cavities were prepared in the mesial and distal surfaces of human molars without any carious lesions. The samples were divided into 4 groups (n=10): Group 1: cavities with 3

3. Salivary Transferrin Levels in Patients with Oral Lichen Planus
Abstract Objective: To compare salivary transferrin levels between patients with oral lichen planus (OLP) and healthy subjects. Material and Methods: In this descriptive, analytical, cross-sectional study, 11 patients with OLP and 22 healthy subjects were selected after matching in terms of age and gender. OLP was confirmed by two oral medicine specialists

4. Perda de massa de nanocompósito jateado com bicarbonato de sódio e exposto à fumaça de cigarro, café e vinho tinto
Abstract Introduction Composite resins are subject to challenges in the oral cavity that are related to patients' habits, which can compromise the restorations’ integrity and longevity. Therefore, it is necessary to study how consuming beverages and smoking cigarettes affects professional prophylaxis. Objective The aim of this study was to evaluate how

5. Comparative study between laser and conventional techniques for class V cavity preparation in gamma-irradiated teeth (in vitro study)
Abstract Objective: The purpose of this study was to compare laser with conventional techniques in class V cavity preparation in gamma-irradiated teeth. Methods: Forty extracted human teeth with no carious lesions were used for this study and were divided into two main groups: Group I (n = 20) was not subjected to gamma radiation (control) and Group II (n=

6. 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

7. Influence of surface moisture condition on the bond strength to dentin of etch-and-rinse adhesive systems
AIM: To evaluate the immediate microtensile bond strength (µTBS) of three two-step etch-and-rinse adhesive systems applied under different dentin surface moisture conditions. METHODS: Class V cavities were prepared in seventy-two bovine incisors. Each tooth was randomly allocated into three groups, according to the adhesive system used: Single Bond 2

8. Influence of light-exposure methods and depths of cavity on the microhardness of dual-cured core build-up resin composites
Objective: The purpose of this study was to evaluate the Knoop hardness number (KHN) of dual-cured core build-up resin composites (DCBRCs) at 6 depths of cavity after 3 post-irradiation times by 4 light-exposure methods. Material and Methods: Five specimens each of DCBRCs (Clearfil DC Core Plus [DCP] and Unifil Core EM [UCE]) were filled in acrylic resi

9. Evaluation of bond strength of silorane and methacrylate based restorative systems to dentin using different cavity models
OBJECTIVE: The aim of this in vitro study was to evaluate the microtensile bond strength (µTBS) to dentin of two different restorative systems: silorane-based (P90), and methacrylate-based (P60), using two cavity models. MATERIAL AND METHODS: Occlusal enamel of 40 human third molars was removed to expose flat dentin surface. Class I cavities with 4 mm me
