Shear Bond Strength of Orthodontic Brackets Bonded with Thermo-Cured Glass-Based Materials-An In Vitro Study.

The results of orthodontic therapy largely depend, among other factors, on the preparation of the tooth enamel itself and the choice of material used to bond orthodontic brackets. The aim of this in vitro study was to determine the shear bond strength (SBS) and adhesive remnant index (ARI) score of thermo-cured glass-ionomers on different pretreated enamel, in comparison with the commonly used composite cement. Three commercially available nano-ionomer or highly viscous glass-ionomer cements (EQUIA Forte Fil, EQUIA Fil, Ketac Universal) and two types of compo-sites (Heliosit Orthodontic, ConTec Go!) were investigated in this study.

The Effect of Chemical Degradation and Polishing on the Gloss of Composite Dental Materials.

This aim of this study was to investigate surface gloss changes of different composite dental materials after chemical degradation or polishing. Five different composites were used (Evetric, GrandioSO, Admira Fusion, Filtek Z550, Dynamic Plus). The gloss of the tested material was measured with a glossmeter before and after chemical degradation in different acidic beverages.

Fusion of Unerupted Mesiodens with a Regular Maxillary Central Incisor: a Diagnostic and Therapeutic Challenge.

The mesiodens is the most frequent type of supernumerary tooth which can appear in the maxillary midline area. The etiology of mesiodentes is not fully understood. This report shows a case of incomplete fusion of an unerupted mesiodens with a permanent maxillary central incisor, aligned in the dental arch.

Assessment of Cytotoxic and Genotoxic Effect of Fissure Sealants in Buccal Epithelial Cells.

Aim: The main purpose of this study was to assess the genotoxic and cytotoxic effect of fissure sealants on buccal epithelial cells.

Material And Methods: The study was conducted on 45 patients (27 girls and 18 boys), seven to 16 years of age (age mean 12.09 ± 2.

Acceptance of Orthodontic Therapy according to the Aesthetic Component of the Index of Orthodontic Treatment Need among Schoolchildren - a Cross-Sectional Study.

Objective: Orthodontic anomalies with impaired facial aesthetics and disturbed oral functions have a major effect on emotional and social development. It is necessary to determine the degree of acceptance of treatment. This study includes an evaluation of the Index of Orthodontic Treatment Need (IOTN) according to the Aesthetic Component (AC) of dental health in schoolchildren.
