- Abstract -

The present study is realised on 348 patients who came to the Prosthetics Clinic of the Faculty of Dental Medicine Craiova for physiognomical and morphofunctional oral rehabilitation during 2008-2009. Out of these there were selected 26 patients who had one or two signs of bruxism.

Considering the global evaluation of patients with bruxism the main factors involved in the ethyology of bruxism were highlighted: the consumption of excitants of CNS, psycho-social factors, occlusal factors and cranium traumatism in antecedents.

The most frequent manifestations of bruxism of the group of patients studied were: teeth grinding, pains at the level of temporo-mandibulary joint (TMJ), morphological disturbances of the dental arches depending on the type of dental wear which can reach different degrees up to the total destruction of the dental crowns, coronary- root fissures and fractures, fractures of the prosthetic dentures or of the placating materials, dentine hyperesthesis and muscular hypertrophy.
The treatment was achieved depending on the level of affectation of the dental tissues. This consisted either of applying some noninvasive therapies at dental level in the case of patients with incipient wear or of making up an ample prosthetical rehabilitation, associated with a general treatment according to recent ethyological hypotheses reffering to bruxism.

Key words: bruxism, dental wear, parafunction.
