Could Bulk Fill Glass Hybrid Restorative Materials Replace Composite Resins in Treating Permanent Teeth?

The study included 44 pediatric patients aged 8 to 16 years who applied to the Pedodontics Department of the Necmettin Erbakan University Faculty of Dentistry. The groups were formed as symmetrical teeth in the same patient using the split-mouth design. The study included class I caries lesions of 144 permanent teeth, 72 of which were restored with the Equia system bulk fill glass hybrid material [Equia Forte HT+Equia Forte Coat (GC, Co, Tokyo, Japan)] and 72 with the Charisma Smart universal composite resin (Kulzer, Gmbh, Hanau, Germany) + Clearfil SE Bond (Kuraray, Noritake, Sakazu, Okayama). Evaluations were performed clinically and radiographically by 2 physicians in the 2nd week, 3rd month, 6th month, and 12th month and the results were recorded. Clinical evaluation was carried out using modified USPHS criteria. Obtained data were statistically analyzed using Kendall's W test and Cochran's Q test for the comparison within the group, and the Chi-Square test for the comparison between the groups.
