Sažetak
Attrition faces are usually seen on the occlusal or incisal surfaces of teeth worn by attrition. They are considered to be a sign of functional and parafunctional activities, and can differ by wideness and position on the teeth. Bruxizm, as a parafunctional activity, is considered to be a risk factor for dysfunction of the masticatory system.
The aim of the study was to investigate the possible relationship between attritional faces, as a sign of bruxizm, and signs of temporomandibular dysfunction. By clinical examination, a group of 100 subjects was selected for trial, based on findings of attritional faces. The severity of attrition faces was quantified on a fivepoint scale ( modified assessment for determination of incisal tooth wear according to Pullinger and Seligman: 0 = no visible tooth wear; 1 = minimal wear of cusps or incisal tips (enamel); 2 = faces parallel to normal planes of contour (enamel); 3 = noticeable flattening of cusp or incisal edges (enamel); 4 = total loss of contour and dental exposure when identifiable (dentin exposure up to half of former crown of tooth): 5 = total loss of contour and dental exposure over half of former crown of tooth). Selected subjects were then examined by standard procedure to investigate the presence of TMD signs. Results showed that there was no statistical significance between signs of TMD and presence of attrition faces, and neither between signs of TMD and severity of attrition faces. Results of this study are compatible with other recent investigations, which show that attrition faces are not a reliable sign for assessing the functional status of the masticatory system.
According to this investigation there is no association between attrition faces and signs of temporomandibular dysfunction.
