“…The fluoride content in the ground water in these areas is high (4.00 parts per million) (Jalil and Tiwari, 1986). This is in contrast to the findings of Daniel (1969) where the incidence of otosclerosis was higher in low fluoride area. Since this study is only a comparison between obliterative and non-obliterative otosclerosis, it is not possible to comment on the role of fluorides in the high incidence of obliterative otosclerosis.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The result of the present study conflicts with that of Daniel (1969) who found a significantly higher incidence of otosclerosis in a low-fluoride area than in a high-fluoride area. In the latter study, the fluoride content of drinking water in the high fluoride area (in Texas) was more than 1.9 mg/1, whereas it was 1 mg/1 in the present study (in Kuopio town).…”

“…However, a number of reports have documented the declining incidence of surgically‐remedial otosclerosis 6–8 . Several reasons for the decline in performance of stapes surgery have been proposed and include an elimination of the backlog of surgeries, fluoridation of the water supply, and widespread measles vaccination 9–13 …”
