Remembering the epidemiology and the possible etiologies of vertical root fractures, the authors distinguish between fractures that occur in vital teeth and vertical fractures of endodontically treated roots. They discuss predisposing factors, onset modality and follow-up. They describe the symptomatology and the few radiographic pathognomonic signs. They show the importance, prognostic and therapeutic purposes, of an exact differential diagnosis as regards periodontal problems. On the basis of personal experience and the literature they believe that the one certain resolutive therapy is extraction in the case of monorooted teeth and the root amputation of the fractured root in case of plurirooted teeth with a good periodontal supporting bone. They conclude by stressing the importance of a preventive global approach to reduce, among other things, the incidence of these unusual conditions that are difficult to diagnose, present no clear signs, and have an unfavourable prognosis. |
