“…Dye penetration was observed not only at the glass tube-material interface, but also into the body of the materials. A similar finding was described in previous studies 3,4,15) . However, the penetration pattern differed with materials.…”

“…Hydraulic temporary sealing materials are based on calcium sulfate: they set upon contact with saliva in the oral cavity. During setting, the materials begin to chemically react and adhere to dentin as they undergo linear hygroscopic expansion like plaster, thereby resulting in good sealing ability [1][2][3][4][5] . However, as water gradually permeates into the material, the setting time will be extended.…”

This study sought to investigate the setting progress and sealing ability of hydraulic temporary sealing materials used in endodontic treatment: Lumicon, Caviton, and HY-Seal. To evaluate setting progress, the materials were filled into glass tubes with one end sealed and immersed in water. After immersion, a measurement apparatus was inserted from the nonimmersed end and the set area was determined by subtracting the unset area from the sample thickness. To evaluate sealing ability, materials were filled into glass tubes and divided into four groups based on different immersion times. Thermal cycling and dye penetration were performed. At 7 days, the setting depths of HY-Seal and Caviton were almost equivalent to full sample thickness, while that of Lumicon was only half of full sample thickness (p<0.01). On sealing ability, Lumicon ranked the highest followed by Caviton, whereas HY-Seal was unstable (p<0.01). These results suggested that there was no correlation between setting progress and sealing ability.

“…Most of these studies have not had any other form of restoration in the tooth and the ability of comprehensive interim restoration(s) to resist bacterial penetration has not been considered. 53,[63][64][65][66][67][68] Dye penetration studies are inexpensive and simple to conduct but no correlation has been established between the penetration of dye through restorations and that of bacteria. In addition there are no studies that compare the validity of dye studies to bacterial tracers.…”

“…Kazemi et al 63 carried out an experiment examining the marginal stability and permeability of Cavit, IRM and Tempit. The first part of the experiment was a simple passive dye penetration study with thermocycling whilst, in the second part, the authors attempted to eliminate the possible effects of the hygroscopic setting mechanisms of the materials.…”

Interim and temporary restoration of teeth during endodontic treatment

One of the main aims of endodontic treatment is to eliminate micro-organisms from within the root canal system. A further aim is to prevent the ingress of any further bacteria during and after treatment. These aims are usually achieved by various means and stages throughout the treatment process. Endodontic treatment is usually performed on teeth that have lost the integrity of the external coronal tooth structure which has allowed bacteria to enter the tooth and ultimately reach the pulp space. Further opening of the tooth occurs when an endodontic access cavity is made to allow treatment to be performed. Hence, there will always be a need for interim and temporary restoration of teeth undergoing endodontic treatment. Many different materials and techniques have been proposed, and these proposals have been based on many research reports. The purposes of this article are to review the literature regarding the use of interim and temporary restorations, and to provide recommendations regarding such restorations for clinicians to follow when providing endodontic treatment.
