There were 73.6 percent of the subjects reported to have light to moderate degree of sensitivity. The difference was significant by age (p 0.001) and by profession groups (p 0.05), but not significant by gender or by education level. Regarding the dental arch distribution, dentine sensitivity frequency was significantly higher on the posterior, mandibular, and the left side. Coldness was reported as the most common stimulus.
