Effect of Triple Antibiotic Paste as an Intracanal Medication With an Anti-Inflammatory Drug on...
Asymptomatic Necrotic TeethThe purpose of this study is to determine whether the use of triple antibiotic paste as intracanal medication with an anti-inflammatory drug, compared to a calcium hydroxide will reduce postoperative pain and intracanal bacteria or not in patients with asymptomatic necrotic teeth.
Digitized Assessment for the Survival of Mature Anterior Teeth With Periapical Lesion After One...
Dental Pulp NecrosisDental Pulp Disease1 moreTrial is designed to allow revascularization and tissue engineering in necrotic teeth with peripical lesion in a single visit approach. different disinfection protocols is used to ensure that adequate disinfection of root canals is achieved to allow stem cells to differentiate and proliferate generating pulp like tissue and turning back tooth to live with periapical healing of resorbed bone.
Root Canal Treatment in Primary Molars With Necrotic Pulp Using Two Different Pulp Therapies
Dental Pulp NecrosisThis is a controlled, randomized, double-blind clinical study (researcher and research participant does not know which group they belong to), with the objective of evaluating clinical and radiographic performances of primary molar canal treatments with necrotic pulps using two obturator pulps. The CTZ paste (composed of chloramphenicol, tetracycline, zinc oxide and eugenol) and the ZOE paste (composed of zinc oxide and eugenol). The CTZ paste represents an alternative treatment that makes possible to treat canals of primary molars in a simplified way, without instrumentation of root canals. Studies with the CTZ pulp have demonstrated satisfactory clinical and radiographic results in addition to biocompatibility and good antimicrobial action. The zinc oxide and eugenol paste has been studied, presents good clinical and radiographic results, it is indicated by the American Academy of Paediatric Dentistry and requires mechanical chemical preparation of the root canals. Children of both sexes, frequenters of the paediatric dentistry clinic of the Federal University of Piaui who present lower deciduous molars with clinical history and / or radiographic evidences of pulp necrosis will participate in the study. The hypothesis of the study is that both pastes present similar clinical and radiographic results.
Antimicrobial Photodynamic Therapy Associated With the Conventional Endodontic Treatment: A Clinical...
Photochemotherapy ReactionDental Pulp Necrosis4 moreMicroorganisms play a critical role in the etiology and pathogenesis of apical periodontitis. Enterococcus faecalis and Candida sp. are frequently associated with persistent infections. The aim of this study was evaluated the antimicrobial photodynamic therapy (aPDT) as an adjunct of the endodontic treatment. Ten uniradicular teeth [control group (CG)=4 and test group (TG)=6] with primary endodontic infections were analyzed. Microbiological samples were collected before and after the chemical-mechanical instrumentation (CMI), after the aPDT (for the TG) and after the temporary restorations removal (second session).
Humeral Head Implants: Radiological and Clinical Evaluation
Idiopathic OsteoarthritisPosttraumatic Osteoarthritis2 moreIn the past years several shoulder reconstruction systems with different types of prostheses and fixation methods have been developed to improve shoulder arthroplasty, trying to cover a wide range of pathologies and revision situations. The aim of the present study is to report radiological and clinical outcome with a stemless shoulder implant with hollow screw fixation.
The Treatment of Initial Stage of Hip Osteonecrosis: the Core Decompression
Hip NecrosisHip InjuriesThis retrospective study evaluates 52 cases of avascular necrosis of femoral head (AVN) treated by core decompression, bone chips allograft, fibrin platelet rich-plasma (PRF) and concentrated autologous mesenchymal stromal cells (MSCs).
Tissue Characterization in Teeth Treated With a Regeneration Protocol
Pulp NecrosisThe purpose of the investigators study is to characterize the composition of the hard and soft tissues present in root canals of teeth previously diagnosed with necrotic pulps and incomplete root formation and treated with a triple antibiotic regeneration protocol. The investigators hypothesis is that treatment of teeth with necrotic pulps and immature apices with triple antibiotic paste will stimulate continued root formation by the deposition of dentin at the root apices. The primary outcome measure will be histological identification of mineralized tissue and adherent cells in the apical third of these teeth.

OsteoarthritisAvascular Necrosis2 moreA clinical Evaluation to determine metal ion release from 4th generation metal-on-metal hip articulating surfaces in cementless total hip arthroplasty.
A Study on M2a Magnum Total Hip Arthroplasty
Degenerative Joint DiseaseAvascular NecrosisThe purpose of this study includes the investigation of Metal-ion release and Renal Function analysis in M2a Total Hip Arthroplasty.
A Randomised Single Centre Study to Compare the Long-term Wear Characteristics of Marathon™ and...
OsteoarthritisPost-traumatic Arthritis6 moreThe purpose of this study is to compare the performance and compare the wear characteristics of two polyethylene cup liners, Marathon™ and Enduron™, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to one of the polyethylene cup liners, Marathon™ or Enduron™ and will be evaluated at regular intervals using clinical and x-ray assessments.
