Introduction: In orthodontic treatment, it is essential to establish a satisfactory bond between enamel and bracket. After the self-etch primers (SEPs) were introduced for the facilitation of bracket bonding in comparison to the conventional etch-and-bond system, multiple studies have been carried out on their shear bond strengths which have yielded different results. This study was aimed at co...

the purpose of this study was to evaluate the effect of er:yag laser on the shear bond strength of resin modified glass ionomer (rmgi) to enamel.twenty extracted caries-free human premolars were selected. the teeth were embedded in acrylic resin. the buccal surfaces of each sample were ground to plane enamel with carbonated disc. the teeth were randomly divided in two groups. in the first group...

introduction: the aim of this study was to assess shear bond strength of composite to dentin after air abrasion and laser treatment. methods: 40 human extracted molars divided into 4 groups (n=10) received the following treatments. group 1: carbide bur, group 2: air abrasion with aluminum oxide 50 μm, group 3: irradiated with erbium-doped yttrium aluminum garnet (er: yag) laser (150 mj/20hz), g...
