Abstract O b j e c t i v e The study evaluated the possibility of extending the use of ozone thera- py in dentistry to the treatment of dentinal hypersensitivity. M e t h o d s The prospective study included 40 patients. All of the enrolled patients were randomized into two groups, allocating one patient to the ozone group and the subsequent one to the paint group. The patients’ respons- es to air stimuli were recorded using a numeric rating scale (NRS), asking each patient to express the degree of pain experienced on a scale of 0 to 10 at baseline, after 14 days and monthly for six months, after the last ozone session. The evaluation was performed by recording the post-treatment hypersensitivity according to the NRS and by completion of a question- naire. R e s u l t s Evaluating the trend of NRS values at the various time points within the two individual groups using the Friedman test, a gradual improvement of the symptoms was registered in the paint group (p < 0.024) and in the ozone group (p < 0.000). C o n c l u s i o n Both therapies proved to be effective. The paint demonstrated an imme- diate desensitizing action, which was not observed in the treatment with ozone. However, in the long term, the paint did not ensure a significant reduction in NRS values. Treatment with ozone proved to be more effec- tive in the maintenance of long-term results.
