Six-year clinical evaluation of packable composite restorations

Area of Science:

• Dental Materials Science
• Restorative Dentistry
• Clinical Trials

Background:

• Resin composites are increasingly used for aesthetic posterior restorations.
• Packable composites offer handling advantages for posterior applications.
• Long-term clinical data on specific packable composites is crucial for material selection.

Purpose of the Study:

• To evaluate the six-year clinical performance of Filtek P60 packable composite restorations.
• To assess the longevity and clinical success of these restorations in Class II cavities.
• To analyze the efficacy of a one-bottle etch-and-rinse adhesive (Single Bond) with packable composites.

Main Methods:

• 47 Class II restorations (Filtek P60/Single Bond) were placed by one operator.
• Restorations were evaluated at baseline and 1, 2, 3, and 6 years using USPHS criteria.
• Clinical parameters included marginal adaptation, form, texture, discoloration, staining, sensitivity, and secondary caries.

Main Results:

• Most restorations maintained acceptable clinical performance (Alpha/Bravo scores) at six years.
• No statistically significant differences were observed across evaluated clinical criteria (p > 0.05).
• Minor issues included slight staining/discoloration in a few restorations; two required repair due to secondary caries.

Conclusions:

• Filtek P60 packable composite restorations demonstrate acceptable clinical performance after six years.
• The combination of Filtek P60 and Single Bond adhesive is a viable option for Class II posterior restorations.
• Long-term clinical serviceability of these posterior composite restorations is supported by the findings.
