sIndicates significant difference in comparison with baseline according to Cochran’s Q test fallowed by McNemar's test (p<0.05) CN: Cention N, GP: G-ænial PosteriorThe outcomes were scored as alpha: clinically very good, bravo: clinically good, acceptable, charlie: clinically unacceptableOne (3%) CN restoration lost retention after 6 months, and two (5.1%) CN and one (2.3%) GP restorations lost retention at 12-month evaluations.Additionally, eight CN (17%) and 1 GP (2%) restorations exhibited bravo scores for marginal adaptation after 6 months and McNemar’s test exhibited changes in marginal adaptation in CN at 6 -month recall (p=0.016). CN showed significantly higher bravo scores than GP (p=0.015). After 12 months, 7 CN (17.9%) and 5 (11.6%) GP restorations were scored as bravo and no significant difference was seen between the groups (p=0.363). Four patients could not attend to the 12-month recall and 1 patient with a bravo score was among them. Both groups showed significant changes in marginal adaptation after 12 months (p=0.004, p=0.019).One (2.1%) CN restoration showed bravo score, whereas all GP restorations were scored as alpha for marginal discoloration at 6-month examinations. At 12-month recall, 1 (2.7%) CN and 2 GP (4.7%) restorations were scored as bravo. However, no statistically significant difference was detected between groups after 12 months (p=1.00).For surface texture, 3 (6.4%) CN and 1 (2.0%) GP restorations showed bravo scores at 6-month evaluations (p=0.357) whereas, 3 (8.1%) CN and 3 (7%) GP restorations were scored as bravo at 12-month recall (p=1.00).In terms of color match, 2 (9.1%) CN restorations showed bravo scores at 6-month examinations. At 12-month recall, 3 (8.1%) CN and 1 (2.7%) GP restorations exhibited bravo scores (p=0.658), but no significant difference was seen between the groups at any evaluation point.No post-operative sensitivity or secondary caries were seen at any recall assessment.The Kaplan–Meier analysis (
