Prevalence of dentin hypersensitivity in Bihar and Jharkhand- A multicentric study

Aim: Dentine hypersensitivity is a common oral problem. This pilot study investigated the prevalence of dentine hypersensitivity in the diverse population across four centres of Bihar and Jharkhand. Materials and Methods: A multi-stage, random sampling method was used to investigate the study population. A total of 5622 subjects were examined at four centres in Bihar and Jharkhand. Subjects were divided into 8 age groups. Participants completed a dentine hypersensitivity questionnaire and underwent clinical examination. The diagnosis of dentine hypersensitivity was confirmed. Gingival recession of sensitive teeth was measured by a Williams periodontal probe. Results: Among 5622 subjects, 1253 were found to be suffering from dentin hypersensitivity indicating a prevalence of 22.28%. Females were more prone to dentin hypersensitivity with male to female ratio of 1:1.31. While subjects in age group of 50-59 were predominantly affected, the molars and premolars were commonly affected with dentin hypersensitivity. Conclusion: The prevalence of dentine hypersensitivity in East India was 22.28%, indicating that it is a common condition. For its effective management, public education about the condition and effective treatment of dentine hypersensitivity are required. Clinical Significance: Assessment of prevalence of hypersensitivity in this demographical location would enable the dental care health workers to devise strategies to educate masses about the prevention and management of this disease
