Influence of primer contamination on the bonding interface of enamel pre-etched with phosphoric acid
نویسندگان
چکیده
In this study, the influence of primer contamination on enamel bonding was analyzed. Adper Scotchbond Multi-Purpose (SMP), CLEARFIL SE Bond 2 (SE2), Universal (SBU) Adhesive, and Etchant (35% phosphoric acid; PA) were used. Ground bovine enamels divided into eight groups based protocols. The interfaces after an acid-base challenge observed via scanning electron microscopy to determine resistant zone (ABRZ). Moreover, nanoleakage analyzed energy-dispersive X-ray spectroscopy. ABRZ in all samples except PA_ONLY (applied PA etching, No adhesive resin). funnel-shaped erosion detected only X_SBU SBU without etching). test revealed silver patterns some groups. nanoleakage, i.e., penetration ions, wherein applied PA-pre-etched enamel.

Background and Aims: Moisture contamination of etched enamel during application of sealant is the most frequently cited reason for sealant failure. In previous studies, some hydrophilic bonding agents have been shown to bond to etched enamel after salivary contamination. The purpose of this study was to evaluate the enamelsealant interface following the use of primer on the saliva contaminated ...

Orthodontic bonding to acid- or laser-etched prebleached enamel
OBJECTIVE Bonding forces of brackets to enamel surfaces may be affected by the procedures used for bleaching and enamel etching. The aim of this study was to investigate the bonding strength of orthodontic brackets to laser-etched surfaces of bleached teeth. METHODS In a nonbleached control group, acid etching (group A) or Er:YAG laser application (group B) was performed prior to bracket bond...
