Inclusion criteria
Inclusion criteria: The inclusion criteria: Patients who have at least three premolars with a class 2 cavity (MO, DO) on each and they can be isolated; After elimination of carious tissue, the gingival margins of all cavities should be placed 1.0 mm above the cemento-enamel junction, 1-1.5 mm in axial depth and ½-2/3 of inter cuspal space in width; The restorative procedure can be performed without need to direct/indirect pulp treatment. The exclusion criteria: Patients exhibiting severe to moderate periodontitis; untreated periodontal disease; uncontrolled caries; marginal recession of the tooth; very poor oral hygiene; heavy occlusal forces such as bruxism and clenching; xerostomia; patients with removable prosthesis or orthodontics appliances or receiving bleaching treatments or ?uoride supplements. Prior to treatment, A Visual Analogue Scale (VAS) is used to assess the patients' opinions toward sensitivity and those with moderate to severe sensitivity (Score 3=) are excluded from the study.
