Alternative technique for class V resin composite restorations with minimum finishing/polishing procedures

Area of Science:

• Restorative Dentistry
• Dental Materials Science

Background:

• Class V restorations are prevalent due to increased non-carious cervical lesions (NCCL), root caries, and an aging population.
• These restorations often exhibit poor durability, high rates of retention loss, marginal excess, and secondary caries.
• Challenges in isolation, insertion, contouring, finishing, and polishing contribute to these clinical issues.

Observation:

• Difficulties in achieving proper isolation and contouring the gingival wall are common in Class V restorations.
• Existing techniques often lead to marginal discrepancies and secondary caries, compromising restoration longevity.
• The need for improved methods to manage the gingival margin in Class V cavity preparations is evident.

Findings:

• A novel technique utilizing a photocured gingival barrier in conjunction with flowable and hybrid resin composites was developed.
• This method facilitates effective isolation and precise insertion of restorative materials.
• The technique allows for the accurate recreation of the gingival wall, minimizing or eliminating excess material.

Implications:

• This technique offers a viable solution to enhance the longevity and success rate of Class V restorations.
• It addresses common clinical challenges, potentially reducing the incidence of restoration failure and the need for replacements.
• Adoption of this method could improve patient outcomes and clinical efficiency in managing cervical restorations.
