Arm && Interventions

Group	Intervention	Description
Filtek™ Bulk Fill Flowable composite	restorative materials	Filtek™ Bulk Fill Flowable Restorative is the 3M ESPE choice in the bulk fill flowable category. Selective etching 15-20 s for enamel. The adhesive system (BISCO universal all bond) will be applied following the manufacturer's instructions (apply 2 coats 20 s before curing). Bulk fill flowable composite will be light cured for 40 s using a visible light curing unit.
ketac N100	restorative materials	Ketac™ Nano Light Curing Glass Ionomer Restorative. Primer will be applied to both enamel and dentinal surfaces for 15 seconds. The prepared tooth surfaces will be wet with the primer for the full application time. Dispensing two clicks from the Clicker™ Dispenser will provide an adequate amount of material for most restorative filling applications. It will be placed with a syringe system then will be placed in 2mm increments or less, and light cured after each increment. An LED curing light will cure all shades with a 20 second light exposure. Finishing Ketac Nano restorative will be polished with conventional finishing and polishing instruments such as a diamond impregnated rubberized polishing system under water spray. A glaze such as Vitremer™ Finishing Gloss will be applied after polishing if desired.
3M™ Ketac™ Universal Aplicap™	restorative materials	3M™ Ketac™ Universal Aplicap™ Glass Ionomer Restorative Clean the cavity preparation with water. Rinse thoroughly and dry. Extrude the mixed ketac universal out of the capsule directly into the prepared cavity with a capsule gun. Please ensure that no air bubbles are included. It is recommended that the finishing and polishing can be continued after approximately 4 minutes after the start of the mixing or earlier if heat is applied for faster setting. The finishing and polishing can be done immediately after final setting with Extra-Fine, Friction Grip diamonds under water-cooling.

Primary Outcome Measures

Name	Time	Method
is marginal integrity of restoration.	12 months	Primary outcome is marginal integrity of restoration. It will be assessed by USPHS; score will be recorded according to USPHS criteria (Nassar et al., 2014).; 1. MARGINAL INTEGRITY; Alpha (A) Visual inspection and explorer The explorer does not catch when drawn across the surface of the restoration toward the tooth, or, if the explorer does not catch, there is no visible crevice along the periphery of the restoration.; Bravo (B) Visual inspection and explorer The explorer catches and there is visible evidence of a crevice, which the explorer penetrates, indicating that the edge of the restoration does not adapt closely to the tooth structure. The dentin and/or the base is not exposed, and the restoration is not mobile.; Charlie (C) Explorer The explorer penetrates crevice defect extended to the dentino-enamel junction.; Delta (D) Mobile, fractured or missing restoration in a part or total
