简要总结
because of the recent introduction of universal adhesives, little information is currently available about the bond durability of universal adhesives to various substrates. Evaluation of bond durability is important since the stability of the bond between the adhesive and substrates is related to the clinical success of restorations. Because significant hydrolysis of the dentin-resin interface occurs after 6-12 months, a clinical trial of at least 18 months' duration is indicated to more accurately depict the likelihood of long-term clinical success
详细描述
Cervical restorations are ever challenging because of difficulties in moisture control, caries access, and proximity to the gingival margin. Both mechanical and non-mechanical factors act to hinder the longevity of cervical restoration newer materials are readily introduced in the market with improved chemomechanical properties, longevity, patient safety, and comfort.
The introduction of new-generation adhesive systems has aimed at reducing technique sensitivity and the number of clinical steps required for adhesion. There has been a trend toward the use of less time-consuming options, continuing this trend, universal adhesives have recently been introduced to the profession. However, because of the recent introduction of universal adhesives, little information is currently available about the bond durability of universal adhesives to various substrates. Evaluation of bond durability is important since the stability of the bond between the adhesive and substrates is related to the clinical success of restorations. Although the most reliable conclusions about the performance of adhesives in the oral environment are derived from clinical trials.
To evaluate the effectiveness and clinical performance of adhesive systems, the American Dental Association (ADA) recommends clinical trials on non-carious cervical lesions (NCCLs), as composite resin restorations only remain bonded to these lesions by the micromechanical interlocking produced by the adhesive systems. The immediate, short-term, and long-term bonding performance of adhesive systems are then evaluated by retention, marginal integrity, and marginal discoloration. There are many attempts to improve bonding to substrates, bond strength, and bond durability, one of these attempts is the newly introduced universal adhesive (BeautiBond ).
