Abstract
Aim: This national survey aimed to evaluate the cumulative severity of dentine hypersensitivity (DH) in Nigerians. Method: 1349 urban and rural Nigerian dwellers aged 18-35 years were studied within a six-month period. Self-administered questionnaire evaluated subject's demography, settlement, and brushing technique. Schiff index Scores were collected and percentages calculated. Gingival recession (GR) was measured, Cumulative Hypersensitivity Index (CHI) Score and the highest Schiff Index Score were recorded per subject. Spearman correlation Coefficients (P-value) were used to assess the relationship between CHI Scores, Schiff Index percentages, and Schiff Index highest per subject. Results: There was statistical significance between CHI, gender, tooth brushing technique and GR (P<0.001). Percentage highest CHI was 18.8% and Schiff score was 35.4%. 26.5% of the respondents had GR greater than 1mm and the overall mean GR was 1.00 ± 1.32. The overall mean Schiff score was 0.54 ± 0.88 while the overall mean CHI was 1.51 ± 2.95. Conclusion: DH is severe in Nigerians and the relationship between this severity, gender and tooth brushing technique is strong. There is a need for the prevention and management of DH in Nigeria.
