No full textClinical evaluation of the use of fiber posts and direct resin restorations for endodontically treated teeth
No full textPURPOSE: Restoration of root-treated teeth is routinely performed in clinical practice with a choice of therapeutic options, considering many factors to provide optimal mechanical properties, esthetics, and longevity. The aim of the present work was to present a preliminary clinical report on the use of fiber posts and direct resin composites for restoring root-treated teeth.
MATERIALS AND METHODS: Thirty-eight anterior and 62 posterior endodontically treated teeth were selected from 3 private prosthodontic offices. The protocol used included endodontic treatment, with translucent fiber posts (DT post) bonded to the post-space using a '1-bottle' adhesive (One-Step, Bisco) and a dual-cure resin cement (DuoLink, Bisco). Direct resin restorations were performed using a micro-hybrid resin composite (Gradia Direct, GC) and a layering technique. Both opaque dentin and enamel and translucent enamel shades were used.
RESULTS: Patients were recalled after 6, 12, 24, and 30 months, and the restorations assessed according to predetermined clinical and radiographic criteria. These clinician-mediated evaluation methods confirmed the good clinical performance of the restorations.
CONCLUSION: Restoration of endodontically treated teeth with fiber posts and direct resin composites is a treatment option, that in the short term conserves remaining tooth structure and results in good patient compliance

No full textSu alcuni specifici ambiti di responsabilità professionale in odontoiatria: in chirurgia estrattiva, nel settore protesico ed implantologico e nell’infezione da HIV
No full textIn the last decades the problem of professional responsibility of the doctors went through deep conceptual re-examination. Some criteria, both general and more technically legal, are presented in order to correctly evaluate the professional liability. Then some specific aspects of the object are examined, such as the damaging of the inferior alveolar nerve after dental extraction, the problems concerning dental prosthetics and implants as well as the questions about HIV infection, acquired by patients or collaborators of the dentist, in his office
