Comparative evaluation of the tensile and compressive strength of three light cured bulk-filled composite core build up material
An in vivo study
Keywords:
comparative evaluation, tensile, compressive strength, bulk-filled compositeAbstract
Introduction- The loss of a considerable amount of tooth structure makes retention of subsequent restorations more problematic and increases likelihood of fracture during functional loading. Different clinical techniques are there, one such technique is post and core. An ideal core build- up material must present excellent mechanical properties to resist the stresses that may be produced during function, providing equitable stress distributions of forces and reducing probability of tensile and compressive failures. Recent developments in flowable and restorative composite resins have resulted in a greater total depth of cure—between 4 and 5 mm for some materials. Materials and Methods: study was conducted in the department of prosthodontics and crown and bridge, including implantology along with external laboratory support and molds for tensile and compressive strength were made. Result- Based on strength, Photocore and Multicore HB may be used as alternatives to Kerr Herculite Precise; however, other physical qualities should also be considered. Conclusion-Within limited data available on recent bulk fill material that is PLT, Kerr Herculite Precis more in vitro and in vivo studies should be held for long term success of the material.
