Early Clinical Performance of Two Powder-Liquid Restoratives in Class-I/II Cavities

Area of Science:

• Dentistry
• Materials Science

Background:

• Dental restorations are crucial for restoring tooth function and aesthetics.
• Powder-liquid dental restoratives offer alternative handling properties and potential benefits.
• Evaluating the early clinical performance of new restorative materials is essential for guiding clinical practice.

Purpose of the Study:

• To compare the 6-month clinical performance of Cention Forte (CF) and Equia Forte HT (EF) in class I/II dental restorations.
• To assess parameters such as surface staining, discoloration, anatomic form, and tooth integrity.

Main Methods:

• A randomized clinical trial (RCT) involving 59 patients with class I/II cavities.
• Each patient received restorations using either CF or EF, randomly assigned.
• Clinical evaluations were performed at baseline (2 weeks) and 6-month recall using FDI criteria.

Main Results:

• A 96.6% recall rate was achieved at 6 months.
• All restorations were clinically acceptable, with one EF restoration showing a repairable marginal defect.
• Both materials showed similar performance in most aspects, except for color match and surface luster. CF had a better initial color match, while EF lost significant surface luster over time due to coating wear.

Conclusions:

• Both Cention Forte and Equia Forte HT demonstrated favorable early clinical performance after 6 months.
• The materials exhibited comparable clinical outcomes in class I/II restorations.
• Further long-term studies are needed to fully assess the durability and longevity of these restoratives.
