Class II Dental Caries
Conditions
Brief summary
Class 2 restorations are analyzed to see whether or not the use of modified universal adhesive will result in similar adaptation to conventional universal adhesive.
Detailed description
The newly modified adhesive with its careful formulation offers: Radiopacity like dentin to reduce the risk of X-ray misdiagnosis and overtreatment. Ability to bond and seal caries-affected dentin to support minimally invasive preparation guidelines and maximize preservation of natural tooth structure. Adhesion to all dental substrates and all direct and indirect materials, including glass ceramics. Full dual- and self-cure compatibility without the need for an additional dual-cure activator bottle. A bisphenol A (BPA) derivative-free formulation to alleviate concerns about BPA in dental materials. A fully aligned system with RelyX™ Universal Resin Cement, offering excellent bond strength for virtually all dual-cure resin cement indications. As with any new material or technique, clinical evaluations are needed to demonstrate the value of universal bonding agents adequately. Therefore, the aim of the current study was to evaluate adaptation of class 2 restorations either using radio-opaque universal adhesive or universal adhesive using digital radiography.
