The objective of the work was to verify the therapeutic effect of sensitive cervical portions of teeth by a combination of a low efficiency Dermalaser and local application of fluoride Elmex fluid. During six sessions the authors investigated the sensitivity to cold and tactile sensitivity of exposed cervical dentin in 256 teeth after provocation, and the desensitizing effects of the applied treatment were evaluated. Combined treatment led to a reduction of the number of teeth hypersensitive to cold and touch and to a decline of the mean hypersensitivity values. The results were tested by regression analysis. The authors assessed also the most frequent causes of dentin exposure and the subjective satisfaction of the patient. The applied treatment proved effective and may become a further extension in the range of therapeutic methods.
