Lavy, E. 244 INTRODUCTION Dental disorders as gingivitis, periodontal diseases and calculus formation are prevalent among dogs regardless of their breed, as they are common in human. Gingivitis and periodontitis are prevalent in 82% of dogs aged 6 to 8 years of age and in 96% of dogs aged 12 to 14 years (1, 2). The incidence of dental disorders increases with age (3). Similarly, in humans, the ...

Background and Aim: White spot lesions (WSLs) are common occurrence following orthodontic treatment, this study sought to compare the remineralizing potential of fluoride, MI Paste Plus (CPP-ACP-F) and Remin Pro for treatment of WSLs. Materials and Methods: This in vitro study was conducted on 56 sound human premolars that extracted for orthodontic purposes. Teeth were cleaned and their root...

statement of problem: the effect of mouth washes on discolouration of dental ceramics with different surface preparations is not well documented. objectives: this in-vitro study has been conducted to evaluate the effect of chlorhexidine (chx) mouth rinse on colour stability of overglazed (op), autoglazed, (ap) or polished porcelain (pop) specimens. materials and methods: the restorative materia...

Introduction: The present study aimed to evaluate an experimental herbal mouthwash, as compared to sodium fluoride mouthwash on the frictional resistance and surface roughness between brackets and two rectangular archwire types. Methods: A total of 60 premolar׳s brackets engaged with 0.019×0.025 archwires made of stainless steel and nickel-titanium alloys were used in this study. The samples we...

At the past, damaged tissue was removed from the body of patients. But now tissue regeneration using scaffolds and implants are used to repair the damaged tissue and organs. Besides of the mechanical properties of metallic biomaterials, they suffer from bioinertness. Using some surface treatment techniques, the bioactivity and also corrosion resistance of titanium implants could be improved. In...

Introduction: Increased consumption of energy drinks has raised concerns about their effects on dental restorations. This study assessed the effects of two energy drinks on the surface microhardness of methacrylate and silorane-based composites after 1-week and 1-month periods. Materials & Methods: In this in-vitro study, 90 cubic samples were prepared from Filtek P90, Filtek Z250 and Filtek Z...

OBJECTIVES To assess the re-hardening potential of enamel matrix derivatives (EMD) and self-assembling peptides in vitro, hypothesizing that these materials may increase the mineralization of artificial carious lesions and improve hardness profiles. MATERIAL AND METHODS Forty-eight enamel samples were prepared from extracted bovine lower central incisors. After embedding and polishing, nail v...

OBJECTIVE To investigate a potential relationship between degree of stretching and resulting permanent deformation of elastomeric chains (ECs) as well as whether or not stretching time has any bearing on the degree of permanent deformation. METHODS Five-module segments of closed elastomeric chains manufactured by 3M Unitek were stretched to 10-100% of their original length in devices especial...
