• Abstract

  Many injuries may assail the tooth lifespan as caries, attrition, abrasion, erosion, trauma, dental restorative procedures, and materials resulting in partial or total loss of the connective pulp tissue. The tissue engineering has been used in an attempt to restore the pulp through pulp repair techniques, when there is partial loss of pulp tissue or by using revitalization/revascularizati…

  Study of cells and tissues involved in the process of repair, and revitalization / revascularization of dental pulp, AP.R

• Abstract

  The dental pulp contains a heterogeneity of cells in its composition, among them stand out from the fibroblasts and odontoblasts. When this tissue is attacked by bacteria and / or their byproducts, odontoblasts and fibroblasts can secrete several inflammatory cytokines in order to attract and activate immune cells to contain infectious agents. IL-1 beta, TNF-alpha, IL-6 and IL-8 proteins …

• Abstract

  It is recognized in the literature that the apical region of the roots presents a varied morphology and can exhibit the presence of numerous ramifications, such as apical delta, secondary and accessory canals. These ramifications may harbor a high prevalence of bacterial cells, capable of proliferating and inducing an inflammatory response, with consequent bone resorption. Thus, it is imp…

• Abstract

  Many injuries may assail the tooth lifespan as caries, attrition, abrasion, erosion, trauma, dental restorative procedures, and materials resulting in partial or total loss of the connective pulp tissue. The tissue engineering has been used in an attempt to restore the pulp through pulp repair techniques, when there is partial loss of pulp tissue or by using regeneration techniques, when …

• Abstract

  The idea that apical ramifications should be filled for successful endodontic therapy has been accepted by many clinicians and researchers. The high percentage of ramifications in the apical portion of root canals indicates the importance of sealing this region, in order to avoid persistent bacterial contamination. Thus, the purpose of this study is to evaluate the sealing of ramification…
