 <\/p>\n

In late 2013, the Foundation approved grants to three research teams who responded to a Request for Application, to investigate different aspects of stem cell regeneration. The research investment was made to help endodontics to ride the tide that promised sweeping changes in clinical practice for both dentistry and medicine. The following grants were paid over a seven-year period.\u00a0<\/span><\/p>\n\n\n\n\n\n\n

Since funding began in 2014, researchers have shifted institutions and projects have developed, resulting in a wide variety of presentations, manuscripts, publications, and additional accomplishments. The Foundation looks forward to reporting additional results from this investment as they become available.\u00a0<\/span><\/p>\n

Prospective and Retrospective Treatment Analysis of Regenerative Outcomes in Immature Teeth<\/i><\/b><\/span><\/h3>\n

The goal of this project is to compare clinical and radiographic outcomes of regenerative endodontic treatment (REGENDO) versus apexification (APEX). We will recruit a multi-centered cohort of previously treated patients by completing a comprehensive chart review to identify eligible patients. This will allow us to identify a retrospective cohort of subjects in an unbiased systematic manner, as well as evaluate documented clinical outcomes and attempt to bring eligible subjects in for an additional follow up visit for clinical evaluation.\u00a0<\/span><\/p>\n

      Regeneration of Pulp Dentin Development in Teeth with Necrotic Pulps and Immature Roots<\/i><\/b><\/span><\/h3>\n

      This exploratory clinical trial is a randomized multi-center clinical trial designed to compare the clinical and radiographic outcomes of a regenerative endodontic procedure using tissue engineering principles (REGENDO), or a revascularization endodontic procedure (REVASC) \u2013 both using a triple antibiotic paste, to that of an apexification treatment using a mineral trioxide aggregate barrier (APEX) for the treatment of permanent teeth with pulpal necrosis and immature apexes.<\/span><\/p>\n

      Presentations of Preliminary Study Results \u2013 In addition to the preliminary Analysis of Microbiological Data for the trial which was presented at AAE19 in Montreal, Canada, the three additional presentations have been made:<\/strong><\/p>\n

            Additional Study Accomplishments:<\/strong><\/p>\n

              \n
            • Microbiological Sample Analysis – Microbiological sample analysis continues; however preliminary analysis has provided exciting information. The microbiological analyses of the data have changed from how it was originally envisioned in the grant due to advances in the technology. One area that may become clinically important in future is metagenomic analyses of the endodontic microbiome to predict microbial virulence and response to antimicrobial treatment. This area of research has not been reported in endodontic research yet.\u00a0\u00a0<\/span><\/li>\n
            • Resident Study Participation – Residents at all study sites played a critical role in the recruitment and execution of study procedures for enrolled subjects. They benefited by performing the endodontic therapy utilizing the research related canal disinfection procedure, performing post-procedure clinical analysis of the treated tooth, and assisting in documentation of their findings at the one- and two-year recall visits. Additionally, because of their work with the study, graduating endodontists gained enhanced knowledge on canal disinfection that will be carried forward in their own practices.<\/span><\/li>\n<\/ul>\n

               <\/p>\n

              Cell Based Approaches to Endodontic Regeneration<\/i><\/b><\/span><\/h3>\n

              The goal of this study is to test whether autologous dental pulp stem cell (DPSC) transplantation is capable of de novo regeneration of pulp-dentin complex and restoration of normal pulp physiology in teeth with necrotic pulp. We will test our hypothesis, “that functional dental pulp restoration and regeneration of pulp-dentin complex in vivo<\/em> necessitates cell-based therapies utilizing DPSC transplantation.”<\/span><\/p>\n
