Dental hypersensitivity is a frequent condition found in the adult population, and it is defined as a pain which appears as a result of the action of a chemical, thermal or tactile stimulus, with a short duration of time . The most frequent causes of dental hypersensitivity are: sensitivity post whitening procedure, gingival recession, abrasion, enamel and dentinal erosion. The use of different desensitizing substances aims to obliterate the exposed dentinal tubules and reduce pulpal sensitivity. The aim of this study is to comparatively evaluate the effectiveness of two fluoridation products (gel and varnish) to reduce dentinal hypersensitivity. Matherial and methods: The study was conducted at the “Grigore T. Popa” Univeristy of Medicine and Pharmacy, Dental Faculty of Iasi, Romania, Discipline of Oro-Dental Prevention. The study had a duration of 6 weeks, on a group of 30 subjects aged 18 to 70 years with dental hypersensitivity. Tactile and cold hypersensitivity was determined. Subjects were divided into 3 groups for each group using a specific type of fluoridation product: group 1- Placebo (chlorhexidine gel – oral Elugelgel, 40 ml (Pierre Fabre), group 2 – Fluoride Protector Gel 20g (Ivoclar, Liechteinstein), group 3- Profluorid Varnish Single Dose 0.40ml (Voco GmbH, Germany). Results: The results of our study show a decrease in sensitivity to the groups in which fluoridation was performed compared to the placebo group. Regarding the reduction of sensitivity compared to gels and varnishes, it was observed that the use of varnish determined a more significant reduction of sensitivity compared to the gel even after the second application. Conclusions: The desensitizing agents used in the current clinical trial have been shown to be effective in reducing dental hypersensitivity with a statistically significant reduction in pain compared to the placebo group, and varnish has been shown to be more effective in reducing dentinal sensitivity compared to the gel tested.
