IMMUNOLOGY

Detailed explanation-1: -Another research reported the prevalence of dentin hypersensitivity varies, but averages about 57 % and peaks between 20 to 40 years of age [15].

Detailed explanation-2: -Conclusion: The prevalence of DH in the Indian population is 20.6%, with a higher predilection for DH in the age cohort 36–45 years and in female subjects.

Detailed explanation-3: -Early research found that all age groups are affected [22], but also an age peak from 30 to 40 years has been reported [18, 21, 23].

Detailed explanation-4: -Dentin hypersensitivity arises when tubules found within dentin become exposed, most commonly caused by gingival recession or enamel wear. Once exposed, these tubules may come into contact with stimuli such as hot, cold and sweet foods and drinks, which can induce the movement of fluid within the tubules.
