The paper presents the results of determining the microhardness of enamel and dentin using the method of indentation of the diamond-pointed pyramid of the device PMT-3 in the teeth with a wedge-shaped defect and teeth with cervical caries as well as their comparison with the indicators of intact teeth. Significant differences have been revealed depending on the type and presence of the pathology: in the enamel of the cervical region, in the dentin of the incisal edge (tubercle) and cervical region (p<0.05). Depending on the topography of the study area in the enamel the differences were unreliable (p> 0.05), in dentin they were statistically significantly different only in clinically intact teeth (p<0.05). The revealed features of microhardness of dental hard tissues are advisable to use when planning treatment and prevention of cervical pathology.
