Exploring Some Aspects Associated with Dentine Hypersensitivity in Children

Table 2

Univariate Poisson regression analysis of the association between children’s dietary habits and presence of dental hypersensitivity.

Dietary habits variables	Total	Children with DH (%)	PR (95% CI)
Soft drinks intake
(ref.: some days)	27	9 (33.3)	1.00	0.192
Everyday	21	11 (52.4)	1.57; (0.79 to 3.10)
Juice intake
(ref.: 3 times/day or less)	24	9 (37.5)	1.00	0.564
More than 3 times/day	24	11 (45.8)	1.22; (0.62 to 2.42)
Tea intake
(ref.: never/rarely)	35	13 (37.1)	1.00	0.277
Once a week or more	13	7 (53.8)	1.45; (0.74 to 2.83)
Citrus fruits intake
(ref.: never/rarely)	32	13 (40.6)	1.00	0.836
Once a week or more	16	7 (43.8)	1.08; (0.53 to 2.18)
Acidic candies intake
(ref.: never/rarely)	8	1 (12.5)	1.00	0.164
Once a week or more	40	19 (47.5)	3.80; (0.58 to 24.95)

DH = dental hypersensitivity; PR = prevalence ratio; 95% CI = 95% confidence interval.
