Filter by:The study compares the prognosis of cases treated with "selective root retreatment" to the cases treated with traditional retreatment approach
The aim of this randomized clinical trial was to compare the incidence, intensity and duration of postoperative pain following the removal of root canal obturation materials canals using rotary (ProTaper Universal or Hyflex EDM) or reciprocating file (Reciproc Blue or WaveOne Gold) systems. The null hypothesis tested was that there is no difference in postoperative pain following the retreatment procedure between the four systems used.
The purpose of this study was to describe the clinical and radiological outcome of root canal treatment with OrthoMTA in primary second molars without successors in which traditional root canal treatment with gutta-percha could not be performed.
The aim of this study was to evaluate the effectiveness of tactile sense, digital periapical radiograph and two different varieties of electronic apex locators at working length determination in primary molars. A total of 30 infected mandibular primary second molar teeth in twelve children aged between 5 and 8 years were included in this study. Working length determination was performed using tactile sense, radiographic method and two different varieties of electronic apex locators (ProPex Pixi® and Ipex®) separately.
This investigation will be a longitudinal clinical trial to study the association of preparation design on the internal and marginal adaptation of the resulting restorations and the long-term clinical performance of chairside CAD/CAM endocrown restorations. Advanced lithium disilicate chairside CAD/CAM endocrowns (CEREC Tessera/Dentsply Sirona) will be adhesively bonded using a selective enamel etch technique with a universal adhesive (Prime and Bond Elect/Dentsply Sirona) and a dual cure resin adhesive cement (Calibra Ceram/Dentsply Sirona). All restorations will be followed over five years of clinical service.
To compare the incidence of post-operative pain after single-visit versus two-visit non-surgical endodontic retreatment.
Does the cuspal reduction during cavity preparation for indirect resin composite restorations in endodontically treated teeth increase the clinical performance when compared to cavities prepared without cuspal reduction?
Aim of the study is to assess canal disinfection using matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) in single visit and multiple visit regeneration protocols, and to assess clinical and radiographic outcomes of single visit and multiple visit regeneration protocols.
This study is a prospective randomized controlled study of patients who come to the University. The aim is to evaluate the success rate of treatment and retreatment of canals using BioRoot ™ RCS cement compared with AH Plus up to 6 years of follow-up. The null hypothesis is that there will be no statistically significant differences in rates of successful treatment of root canals filled with BioRoot ™ RCS compared to gutta-percha and AH Plus sealer.
This study is a prospective randomized controlled study of patients who come to the University and non-surgical root canal retreatment is considered as the election of choice in presence of periapical disease. The aim is to evaluate the success rate of non-surgical retreatment performed in one compared to two visit treatment up to 10 years of follow-up. The null hypothesis is that there will be no statistically significant differences in rates of success, when performing root canal non-surgical retreatment in one or two visits.
