چکیده
Abstract This in vitro study used the same frequency and duration of acid contact as a previous situ/in vivo to evaluate effect erosion on CAD/CAM restorative materials human enamel compare effects challenges enamel. The (IPS e.max CAD, Lava Ultimate, PMMA block) were eroded by immersion 150 ml cola drink for 14 days (4 × 5 min/day). surface microhardness roughness specimens measured at baseline (T1), day 7 (T2), (T3). substance losses T2 T3. data statistically analyzed using repeated measures ANOVA Bonferroni's test (α = 0.05). Erosion significantly decreased (all P

reinforcement of unsupported enamel by restorative materials and dentin bonding agents: an in vitro study
objective: preservation of unsupported occlusal enamel after removal of underlying carious dentin may result in maintenance of aesthetics as well as wear resistance against the opposing enamel. this study investigates the influence of different restorative materials and bonding agents on reinforcement of unsupported enamel in molars and compares it with sound dentin. materials and methods: in t...
متن کاملErosion and abrasion of tooth-colored restorative materials and human enamel.
OBJECTIVES The aim of this study was to investigate the effects of erosion and toothbrush abrasion on different restorative materials and human enamel. METHODS Human enamel and 5 kinds of tooth-colored restorative materials were used. The restorative materials included three composite resins (Filtek Silorane, Tetric EvoCeram, and Tetric EvoFlow), a polyacid-modified composite (Dyract Extra), ...

متن کاملThe Comparison of Solubility and Release of Fluoride from Easthetic Restorative Materials in Water and Acid: An In Vitro Study
Background & Aims: Secondary caries is one of the most common problems in restorative dentistry. The release of flouride ions could substantially benefit the tooth enamel and neigboring dentin because flourid can combat caries. The purpose of this in vitro study was to evaluate the solubility rate and release of fluoride from tooth-colored restorative materials (Iono CID, Fuji II LC, FugiIX, Fu...
متن کاملThe Preventive Effect of Remin Pro and Neutral Sodium Fluoride on Erosion of Dental Enamel: An In Vitro Study
Background and Aim: Carbonated diet soda is the most common etiologic factor for dental erosion, and fluoride products have been proposed as an option for the preven-tion of that problem. This study evaluated the effect of Remin Pro and neutral sodium fluoride on the prevention of dental enamel erosion using profilometry. Materials and Methods: This study was conducted using an experimental-...
