Outcome Measures

Primary Outcomes (4)

  • Retention

    Observers evaluated the restorations was performed using the United State Public Health Service criteria regarding retention rate. Retention rate was evaluated by 2 independent clinicians. Scores: Alfa: No loss of restorations materyal. Charlie: Any loss of restorative material

    [Time Frame: From baseline to 24 month]

  • Marginal discoloration

    Observers evaluated the restorations was performed using the modified United State Public Health Service criteria regarding Marginal staining. Marginal staining was evaluated by 2 independent clinicians. Visual inspection with a mirror was performed. Scorsese: Alfa: No discoloration. Bravo: Discoloration without. Charlie:Discoloration with penetration in pulpal direction

    [Time Frame: From baseline to 24 month]

  • Marginal Adaptation

    Observers evaluated the restorations was performed using the modified United State Public Health Service criteria regarding marginal adaptation. Marginal adaptation was evaluated by 2 independent clinicians. Visual inspection with a mirror was performed. Scores; Alfa: Closely adapted, no visible crevice. Bravo: Visible crevice, explorer will penetrate. Charlie: Crevice in which dentin is exposed

    [Time Frame: From baseline to 24 month]

  • Seconder Caries

    Observers evaluated the restorations was performed using the United State Public Health Service criteria regarding retention rate. Retention rate was evaluated by 2 independent clinicians. Scores: Alfa: No caries presented. Charlie Caries present

    [Time Frame: From baseline to 24 month]

Study Arms (2)

Cerasmart 270 (GC Coop, Tokyo, Japonya)

EXPERIMENTAL

Composition: Bis-MEPP, UDMA, dimethacrylate, silica (20 nm), barium glass (300 nm) 71 wt% Tooth measurement and digital design are done using a camera. The design is sent to a milling device for restoration fabrication. Tooth surface is roughened with 37% orthophosphoric acid for 10 seconds, air dried, and Adhesive Primer is applied. Inner surface of the endocrown restoration is sandblasted with aluminum oxide powder, cleaned with alcohol, and coated with Adhesive Primer. CEM ONE self-adhesive resin cement is applied to the tooth surface, and the restoration is cemented.Final polymerization process lasts 10 seconds per surface to ensure bonding.Rough edges of the restoration are polished with diamond burs and discs. Excess material is removed, and occlusion and tooth areas are checked.Any cement residues in the mouth are carefully cleaned.

Device: Cerasmart 270 (GC Coop, Tokyo, Japonya)Device: : G-CEM ONE (GC Coop, Tokyo, Japonya)

EverX Flow (GC Coop, Tokyo, Japonya)

EXPERIMENTAL

Resin: semi-IPN matrix composed of Bis-GMA, TEGDMA and PMMA. Fillers: E-glass fiber, barium borosilicate (57 vol%) After cavity preparation, 37% phosphoric acid gel will be applied to the enamel for 30 seconds, washed with water and dried slightly. G-Premio Bond adhesive agent (GC, Tokyo, Japan) is applied to the enamel and dentin surfaces with a disposable applicator for 20 seconds and waited for 10 seconds according to the manufacturer's recommendations. Then, air is squeezed with light air pressure for 5 seconds and polymerised with LED light at 1200 mW/cm2 for 10 seconds. The restoration walls are formed with composite G-ænial™ A'CHORD (GC, Tokyo, Japan). EverX Flow composite (GC, Tokyo, Japan) is applied to the cavities in 4 mm layers and polymerised with light for 10 seconds. G-ænial™ A'CHORD (GC, Tokyo, Japan) composite is applied on the top layer. It is shaped with finishing cutters and polished with polishing rubbers.
