Assessment of Microhardness of Conventional and Bulk-Fill Resin Composites Using Different Light-Curing Intensity.

(1) Background: This study evaluates the effect of a conventional/low-voltage light-curing protocol (LV protocol) (10 s with 1340 mW/cm) and high-voltage light-curing protocol (HV protocol) (3 s with 3440 mW/cm) on the microhardness (MH) of dental resin-based composites (RBCs). Five resin composites were tested: conventional Evetric (EVT), Tetric Prime (TP), Tetric Evo Flow (TEF), bulk-fill Tetric Power Fill (PFL), and Tetric Power Flow (PFW). (2) Materials and Methods: Two tested composites (PFW and PFL) were designed for high-intensity light curing.

The Influence of Different Occlusal Loading on Six Restorative Materials for Restoration of Abfraction Lesions-Finite Element Analysis.

Objectives:  The aim of the study was to analyze the occurrence of stress on teeth with abfraction lesions restored with six different restorative materials, and by introducing the tensile strength parameters to calculate the safety factor of the material under the load (ratio between the strength of the material and the maximum stress).

Materials And Methods:  Three-dimensional models of the mandibular premolar are created from a microcomputed tomography images. An abfraction lesion is modeled on the tooth.

Prevalence of TMD among Children Provided with Fixed Orthodontic Treatment.

Background: According to available scientific references and textbooks, there are contradictory views concerning the etiology of signs and symptoms of TMD.

Objectives: The aim of this study was to determine a correlation between the incidence of signs and symptoms of TMD in children aged 12-18 who do not wear a fixed orthodontic appliance and the incidence of signs and symptoms of TMD in children who wear a fixed orthodontic appliance.

Material And Methods: The total number of 120 subjects were included in this survey and divided into two groups.

Evaluation of Solubility of Luting Cements in Different Solutions.

Objective: To evaluate and compare the solubility of three luting cements in three different solutions: distilled water and artificial saliva with different pH values (7.4 and 3.0).

The Influence of Gender on the Cortical Width of the Lower Border of the Mandible and the Mandibular Cortical Index.

Objective: To evaluate the influence of gender on the mental index (MI) and the mandibular cortical index (MCI).

Methods: In this study, there were 120 subjects (43 male and 77 female subjects), who had undergone a dental panoramic radiograph examination for the needs of diagnosis and future treatment planning. MI and MCI were determined by orthopantomograph.

Evaluation of the water sorption of luting cements in different solutions.

Objective: To evaluate and compare the water sorption of three luting cements in three different solutions: distilled water and artificial saliva with different pH values (7.4 and 3.0).

Comparison of Results of Measurement of Dimensions of the Placed Dental Implants on Cone Beam Computed Tomography with Dimensions of the Producers of the Implants.

Introduction: One of the most frequently used method for scanning patients with indication for dental implantation in dentistry is cone beam computed tomography. Implantation, CBCT imaging and implant programme are inevitable when planning a successful replacement of lost teeth. CBCT offers exact information about available bone and its density, adjacent tooth roots, the place of mandibular canal and maxillary sinus and adjacent anatomical structure.

Radiographic Evaluation of Crestal Bone Loss Around Dental Implants in Maxilla and Mandible: One Year Prospective Clinical Study.

Purpose: The aim of the study was to analyze the amount of maxillary and mandibular crestal bone loss around Bredent Sky Blue type of implants of different dimensions one year after implantation.

Materials And Methods: 36 implants of diameter 3.5 x 10 mm were inserted in the maxilla and 12 in the mandible.
