N/A Dental Caries. Intervention 1: Intervention group1: The intervention was Fissure sealant treatment carried out by the senior dental students. It was provided as a part of "field program” of Department of Oral Public Health in 2015. Teeth of contrary two quadrants (36–46 and/or 16–26 teeth) were randomly allocated in either the intervention or the control groups. Teeth with deep pit and fissures either healthy or at early stages of enamel decay (ICDAS 0-2) were included in the study and regarding the six codes of ICDAS dental caries, severity for all full-erupted first permanent molars was recorded at baseline. The treatment process included cleaning teeth with low-speed tooth brushing without prophylaxis paste, isolation with cotton rolls and suction, etching with Ultra etch gel (35% phosphoric acid, ultradent Products Inc, USA) for 30 seconds. After thoroughly water rinsing and air drying, applying the bonding agent by Single Bond 2(3M ESPE, USA) and curing, resin-based sealant was applied (Prime-Dent®. Prime Dental manufacturing Inc.3735 W. Belmont Ave. Chicago) to the pit and fissures on the occlusal and buccal surfaces. Using curing light (device LED light cure Woodpecker Medical Instrument Co, China 400-600 mw/cm2) all coated surfaces exposed for 45 seconds. After setting the sealant, teeth were checked by supervisors for retention, air bubbles and occlusal adjustments. If necessary, the processes were repeated. Intervention 2: Control group: The teeth in the contrary quadrant received no treatment.
