The primary function of a temporary filling material is to prevent the contamination of the root canal system by fluids, organic debris, and bacteria from the oral cavity in multiple-appointment root canal treatment. The aim of this study was to evaluate the sealing ability of a new temporary filling material Orafil LC compared with Cavit G and IRM using a dye penetration test. Standard endodontic access cavities were prepared in 24 human premolars. The teeth were divided into three groups (n = 8 for each group). Samples are de-coronated at the level of CEJ, 4mm of obturated material was removed from the coronal portion and were sealed with one of the three temporary restorative material. Samples were immersed in 2% methylene blue dye solution for 3 days. The teeth were then rinsed, dried, sectioned in bucco‑lingual direction and evaluated under a stereomicroscope for dye penetration. Data were analysed. The dye penetration was observed in all experimental groups. The lowest mean leakage was in Cavit G followed by (in ascending order of dye penetration) IRM, Orafil LC. Dye penetration was observed in all the samples. Cavit G exhibited minimal dye penetration when compared to IRM and Orafil LC. Within the limitation of the present study Cavit G is considered to be a promising option for the provisional restoration of endodontically treated teeth
