introduction: the aim of this study was to compare the antibacterial efficacy of diode laser 810nm and photodynamic therapy (pdt) in reducing bacterial microflora in endodontic retreatment of teeth with periradicular lesion. methods: in this in vivo clinical trial, 20 patients who needed endodontic retreatment were selected. after conventional chemo mechanical preparation of root canals, microb...

introduction: the main goal of this ex vivo study was to assess and compare the cellular and electrophysiological effects of two dental biomaterials, white mineral trioxide aggregate (wmta) and calcium enriched mixture (cem) cement, on neuronal cell excitability and electrical properties. materials and methods: a conventional intracellular current clamp technique was used to study the cellular ...

This study analyzed the antimicrobial effect of photodynamic therapy (PDT) in association with endodontic treatment. Twenty patients were selected. Microbiological samples were taken after accessing the canal, endodontic therapy, and PDT. At the end of the first session, the root canal was filled with Ca(OH)(2), and after 1 week, a second session of the therapies was performed. Endodontic thera...

AIM To determine whether the following can be sterilized by autoclaving - endodontic sponges, rotary nickel-titanium (NiTi) instruments within endodontic sponges, and rotary NiTi instruments with rubber stoppers. METHODOLOGY Sixty-four samples of eight different endodontic sponges (n = 512) were placed into brain heart infusion broth (BHI) for 72 h. An aliquot of this was then spread onto hor...

The prosthetic treatment of seriously damaged, endodonticallytreated teeth often require an endodontic post as an additional retention element for core build-up prior to crown restoration. In addition to metal-based posts and zirconia-based ceramic posts, fiber-reinforced composite posts have recently become a center of interest for dentists and science. In the past it was commonly accepted tha...
