Abstract

Background: Bacterial infection of teeth is the most common cause of pulpal and periradicular diseases. Infected root canals require dressing with antibacterial medicaments in a multi-visit root canal treatment in which temporization of endodontic access cavities becomes mandatory. Lack of satisfactory coronal temporary restorations can lead to failure of endodontic therapy. The aim of our study was in vitro comparative evaluation of coronal sealing ability of various temporary restorative materials in endodontic therapy using stereomicroscope analysis. Materials and Methods: Eighty extracted human permanent maxillary first and second premolar teeth were selected. Standardized endodontic access cavity preparations with dimensions of 5 × 5 mm were done, and root canal orifices were located. All the specimens were then randomly divided into nine groups; seven experimental and two control groups. Experimental groups; Group 1: Orafil-LC (n = 10), Group 2: Cavit-G (n = 10), Group 3: Coltosol-F (n = 10), Group 4: MD TempPlus (n = 10), Group 5: Zinc Oxide Eugenol (n = 10), Group 6: Orafil-G (n = 10), Group 7: TMP RS (n = 10) used as coronal temporary restorative materials. Control group: Positive control (n = 5), negative control (n = 5). Temporary restorative materials were placed in all specimens over the cotton pellets except in the control group. All specimens were incubated at 37°C for 48 h; thermocycling of all specimens was done and were then placed in Indian ink dye at room temperature for 7 days. All specimens were then sectioned mesio-distally, examined under stereomicroscope at ×10 magnification. Degree of dye penetration was evaluated using 4-point scale grading criteria and obtained data was tabulated. Results: Tabulated data were statistically analyzed using one-way analysis of variance test, student “t” test, and Fisher Exact test, P ≤ 0.05 was considered statistically significant. Group1 showed the least dye penetration with superior coronal sealing ability, followed by Group 2 and Group 3. Group 5 and Group 7 showed maximum dye penetration with poor coronal sealing ability. Conclusion: Premixed Orafil-LC and Cavit-G as coronal temporary restorative materials in endodontic access cavities exhibited the least dye penetration with superior coronal sealing ability among the seven restorative materials tested.
