Context: One of the undesirable characteristics of dental composite resin is the polymerization shrinkage and the associated microleakage. The snowplow technique of placement and the preheating of the composite resins are methods to minimize microleakage.
Aim: The aim of this study was to comparatively evaluate microleakage in Class II cavities restored with snowplow technique using either preheated packable or flowable bulk-fill composite resin.

Background: The success of the root-end procedure depends on the regeneration of the functional periodontal attachment system, including the cementum on the resected root-end surface, periodontal ligament (PDL), and alveolar bone. As root end filling materials remain in close contact with live periapical tissues, they may influence the endodontic treatment outcome.
Aim: To assess and compare the cytotoxicity and genotoxicity of three root repair materials, mineral trioxide aggregate (MTA), endosequence, and geristore in human-cultured periodontal ligament fibroblasts.
Background: Evaluation of the biomechanical response of tooth with perforation repair is important to attain predictable prognosis. It may remain altered even after perforation repair due to the loss of tooth structure.
Aim: The aim of this study is to assess and compare the effect of pulpal floor perforation repair of different sites with biodentine, on the biomechanical response of mandibular molar through 3-dimensional (3D) finite element analysis (FEA).
