[Root cracks and fractures. Clinical diagnosis--prognosis].

The diagnosis as well as the therapy of fractured teeth are often a real problem for the general practitioner. Their major etiology is iatrogenic but is sometimes accidental or parafunctional. In order to avoid complications we should as a rule use the least invasive techniques in our therapies. The rapidity and the extent of periodontal destruction induced by these lesions impose a precise diagnosis and in most cases an extraction without any delay.
