Tooth Sensitivity in Fluorotic Teeth
Tooth sensitivity also known as dentin hypersensitivity affects the tooth or exposed root surfaces. This occurs when the enamel that protects our teeth gets thinner, or when gum recession occurs, exposing the underlying surface, the dentin, thus, reducing the protection the enamel and gums provide to the tooth and root. Tooth sensitivity affects up to 57% of the population. The chief symptom of tooth sensitivity is rapid, sharp pain against tactile (i.e. tooth brushing), thermal (hot or cold) and chemical (acids and sweet) stimuli, as well as exposure to air.

The aim of this study was to compare the demographic and clinical features of tooth sensitivity (TS) in subjects with and without fluorosis. A total of 2249 subjects (378 subjects with fluorosis and 1871 subjects without fluorosis) were examined for TS during a study period of one year and TS was determined in 122 subjects. The level of TS was evaluated on a visual analogue scale (VAS). The sensitivity evaluation was made by applying tactile and cold air stimuli. In teeth sensitive to any stimuli, the plaque index (PI), gingival index (GI), gingival recession (GR) and periodontal pocket depth (PPD) were recorded. Fluorosis was assessed using the Dean Index. One hundred and twenty-two participants were found to have TS (5.42%). The frequency of TS in subjects with fluorosis was 9.26%, while the frequency of TS in subjects without fluorosis was 4.65%. There were no significant differences between the groups for periodontal parameters except PI. The results of the study showed that the subjects with fluorosis may have been suffering from TS more than the subjects with normal dentition
