[Correlation between occluding trauma and dental erosion]

The study presents data obtained by examination of a lot of patients with erosions of the teeth. At the same time histologic sections were prepared from teeth with cuneiform lesions that had to be removed as a result of parodonthopathic processes. Histological studies that have been carried out have demonstrated hyperemia of the dental pulp, and blood suffusion, sometimes accompanied by oedema. Slight rarefaction of dentine was also noted in other microscopic fields, with characteristic enlargement of the interdentinal spaces. The fact that the histological picture does not provide too much data on the etiopathogenic mechanism of the cuneiform lesions it may be considered that the occluding trauma is one of the major causes of these coronal lesions. Occluding balancing as performed by the authors in these patients have always demonstrated the presence of erosions in teeth that had suffered from occluding trauma. By this attitude and with these means of therapy one can prevent the development of new lesions of the cuneiform type, and thus contribute to the decrease in the morbidity, and to the prevention of the various disturbances in the dentomaxillary apparatus.
