About

Class V restorations are evaluated to reveal whether the use of modified universal adhesive will have a similar performance compared to conventional universal adhesive or not.

Full description

The innovative Scotchbond Universal Plus Adhesive offers all the benefits of its predecessor, Single Bond Universal Adhesive as demonstrated by a 3M field evaluation comparing the performance of the two products. These benefits include:

  • Compatibility with all etching techniques - total-etch, self-etch, and selective enamel etch.
  • Usage with direct and indirect indications.
  • Bonding to all dental surfaces without the need for separate primers or silanes
  • Virtually no post-operative sensitivity.

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 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, long-term clinical evaluations are needed to demonstrate the value of universal bonding agents adequately. So, the aim of this study is to evaluate the clinical performance of the modified universal adhesive, versus the conventional universal adhesive, for restoring carious class V cavities over one year and a half.

50 participants in 2 patient groups

Carious cervical lesions treated with modified universal adhesive
Experimental group
Description:
Preparation of class V cavity with removal of caries and beveling of margins is done followed by total etching prior to application of modified universal adhesive. The cavity is then restored with nano-filled resin composite.
Treatment:
Drug: Modified universal adhesive
Carious cervical lesions treated with conventional universal adhesive
Active Comparator group
Description:
Preparation of class V cavity with removal of caries and beveling of margins is done followed by total etching prior to application of conventional universal adhesive. The cavity is then restored with nano-filled resin composite.
Treatment:
Drug: Conventional universal adhesive
