Tightness of two coronal obturation techniques: Comparative study
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 4
Abstract
The purpose of this study is to evaluate the tightness of four composites: Bulk fill, hybrid, microhybrid, nanohybrid composite, and to compare the bulkfilling technique with the oblique obturation technique. Materials and methods: 120 proximal cavities (4 × 4 mm) were performed on 60 molars. The cavities were randomly assigned to 4 experimental groups (n = 30). Group 1: monoblock obturation technique with Bulk fill composite Group 2: oblique obturation using the hybrid composite Group 3: oblique obturation using the microhybrid composite Group 4: oblique obturation using the nanohybrid composite. After the cavities were filled, the specimens were immersed in a 1% methylene blue solution for 18 hours and then rinsed with running water. The teeth were cut longitudinally, removing the buccal face of the tooth The tooth-composite joint was photographed using a digital SLR camera The statistical analysis of the results was done by the software Epi info 6.0. Results: Group 1 has an average infiltration of 0.900 mm lower than group 2 and group 3, Group 1 has an average infiltration of 0.900 mm superior than group 4. Conclusion: Filling using the bulkfill composite is more efficient than the oblique obturation using the hybrid composite. The oblique obturation using the microhybrid and nanohybrid composites showed a similar tightness than the composite Bulk fill.
