Prevalence of buccal cervical dentine hypersensitivity and related risk factors - A cross-sectional study

Background: This study was done to assess dentinal hypersensitivity in a population and related risk factors that enhance its prevalence. Aim: This cross-sectional study aimed to demonstrate the prevalence of buccal cervical dentine hypersensitivity (DH) and related risk factors. Materials and Methods: The total number of 135 subjects, aged 20-65 years was diagnosed with DH included in the study. All the subjects completed a self-administered questionnaire and were further examined using a three-way syringe used to put a rush of cold air which further helps in establishing DH diagnosis. Furthermore, in our study, we used one more criteria of recording buccal gingival recession which was associated with sensitive teeth only, using UNC-15 probe. Results: The prevalence of DH was 64.2%. First premolar was the most commonly affected tooth. The risk factor which exaggerates DH response related to periodontal diseases includes poor oral hygiene and clinical attachment loss (gingival recession). The predominant risk factors appear to be horizontal tooth brushing and acidic beverage intakes such as juices and soft drinks. Conclusion: The study assessed the prevalence of DH and enlightens predominant risk factors which further enhance its occurrence. DH is important to recognize to manage it clinically and to take preventive measures for patient benefits. Clinical Significance: In this study, the prevalence of DH was found to be 64.2%, high compared to many published data, further provides strong-related risk factors that help in the clinical management of dentinal hypersensitivity pain and to take preventive measures that will be beneficial to the patients.
