the study was conducted to compare and evaluate the clinical performance of EQUIA Forte and SDR® flow+ in class II cavities in primary molar

Initial intra-oral periapical bitewing radiographs of the teeth to be treated were taken before the procedure. After obtaining partial isolation using cotton rolls and saliva ejector, caries excavation and removal of undermined enamel will be done using high-speed diamond burs with water cooling and hand instruments. After finishing the cavity, a matrix band will be placed with the interproximal wedge. The prepared cavities will be restored using Equia Forte or flowable bulk-fill composite resin according to the manufacturer's instructions.
