Performance of 2 packable composites at 12 months

Area of Science:

• Restorative Dentistry
• Dental Materials Science

Background:

• Marginal seal is critical for the longevity of dental restorations.
• Packable resin composites are commonly used for moderate to large molar lesions.
• Evaluating the marginal integrity and staining of these materials is essential.

Purpose of the Study:

• To compare the marginal seal of two packable resin composite materials (Alert and SureFil) in moderate to large molar lesions.
• To assess the impact of a surface sealer on the marginal seal and staining of these composites.
• To evaluate the clinical performance of the restorations over 12 months.

Main Methods:

• A randomized, double-blind clinical trial involving 50 participants with moderate to large molar lesions.
• Restorations were placed using either Alert or SureFil resin composite, with or without a surface sealer.
• Clinical performance, including marginal staining, was evaluated at baseline, 6 months, and 12 months.

Main Results:

• At 12 months, 90.5% of Alert restorations and 68.2% of SureFil restorations showed no marginal staining.
• No statistically significant difference in marginal staining was found between the two restorative materials.
• Overall, 3 restorations were classified as failures, with no significant difference attributed to the flowable liner.

Conclusions:

• Flowable liners did not significantly reduce marginal staining in restorations made with the tested resin composite materials at 12 months.
• Both Alert and SureFil demonstrated acceptable clinical performance regarding marginal seal in this study.
• Further research may explore long-term outcomes and different application techniques.
