The aim of the present population study was to evaluate the impact of early childhood caries (ECC) on the oral health-related quality of life (OHRQoL) of preschool children and their parents/caregivers. A random sample of 638 children (aged 2–5 years) underwent a clinical oral examination to assess ECC, and their parents were invited to answer two questionnaires: one on the OHRQoL of the child, the Early Childhood Oral Health Impact Scale, and another on the characteristics and sociodemographic conditions of the child. Descriptive analysis, χ2 test, Mann-Whitney test, Kruskal-Wallis test, and hierarchically adjusted Poisson regression models were used. The prevalence of ECC was 52.2%. The number of teeth with decay ranged from 1 (n = 42; 6.6%) to 20 (n = 5; 0.8%), averaging 2.86 (SD = 4.04). There was a significant difference between the severity of ECC and OHRQoL in terms of the impact on both child and family (p < 0.001). An increase in the severity of ECC resulted in an increased negative impact on the quality of life of the child (rate ratio, RR = 5.32; 95% confidence interval, CI: 3.67–7.71). Greater age of the mother had a positive impact on the OHRQoL of preschool children (RR = 0.72; 95% CI: 0.54–0.97). Increased age resulted in an increased negative impact on the quality of life of the child (RR = 2.97; 95% CI: 1.61–5.47). ECC has a negative impact on the OHRQoL of children aged 2–5 years and their parents. Mothers aged 30 or older reported better OHRQoL, independent of the presence of ECC and the age of the child.
The aim of this study was to assess the prevalence of early childhood caries (ECC) in children and investigate the influence of sociodemographic variables, quality of oral hygiene and child-related aspects. A cross-sectional study was carried out with 593 children aged three to five years. Data were collected through clinical examinations and interviews with parents. Interviews with parents of the children were conducted to acquire information on sociodemographic aspects, breastfeeding, bottle feeding and harmful oral habits. Statistical analysis involved the chi-square test and the Poisson regression. The prevalence of ECC was 53.6%. The occurrence of ECC was greater among children with unsatisfactory oral hygiene (PR: 2.95; 95% CI: 2.42-3.60) and those from a family with a lower monthly household income (PR: 1.62; 95% CI: 1.24-2.10). In conclusion, unsatisfactory oral hygiene and monthly income exerted an influence on the occurrence of ECC among preschoolers.
Dental caries was associated with a negative impact on the quality of life of children. Malocclusion and DDE did not cause a negative impact on the children's quality of life. Older children had higher frequency of negative impact on OHRQoL.
There are no longitudinal studies that assess the impact of traumatic dental injury (TDI) on the oral health-related quality of life (OHRQoL) of preschool children. To investigate the impact of TDI on OHRQoL among preschool children, a population-based case-control study was carried out with a representative sample of 335 children, 3-5 years of age, enrolled at public and private preschools in the city of Campina Grande, Brazil. The case group and the control group were matched for age, gender, type of preschool and monthly household income at a ratio of 1:4 (67 cases and 286 controls). Impact on the OHRQoL of children was assessed through administration of the Early Childhood Oral Health Impact Scale (ECOHIS). The occurrence of TDI was determined through clinical examinations performed by three calibrated dentists. Data analysis involved descriptive statistics, McNemar's test, the chi-square test with linear trend and conditional logistic regression analysis [P≤0.05; 95% confidence interval (95% CI)]. The most frequent responses were 'felt pain' (19.4%) and 'difficulty eating' (16.4%). The prevalence of TDI was 37.3% in the case group and 33.9% in the control group. No statistically significant differences were found between case and control groups regarding the presence of TDI (odds ratio=1.16; 95% CI: 0.66-2.02). TDI had no impact on the quality of life of preschool children.
The aim of the present study was to determine the concentration of total fluoride (TF) and total soluble fluoride (TSF) in children's dentifrices marketed in the city of Lima, Peru. Three samples of 23 dentifrices (4 without fluoride and 19 with fluoride) were purchased in different pharmacies in Lima, Peru. The TF and TSF concentrations found in the dentifrices were determined by ion-selective electrode, expressed in ppm F (μg F/g of dentifrice). The TF concentration in the majority of the fluoride toothpastes matched that shown on the label, except for one declared as 1450 ppm F by the manufacturer, whereas only 515.1 ppm F was found. The concentration of TSF found in the fluoride toothpastes ranged from 457.5 to 1134.8 ppm F. All the dentifrices were formulated with silica, but one also presented calcium carbonate. In conclusion, 83% of the children's dentifrices marketed in Lima, Peru, were fluoridated, but only 53% contained a TSF concentration greater than 1000 ppm F, the minimum concentration required to provide an anticaries effect.
The aim of this study was to evaluate the impact of dental caries, traumatic dental injuries (TDI), toothaches, and malocclusion on the oral health-related quality of life (OHRQoL) of the families of Brazilian preschool children. A population-based, matched case-control study involving 415 pre-schoolers aged 3-5 years was conducted. The case (impact on OHRQoL) and control groups (no impact on OHRQoL) were matched for age, gender, and family income at an 1:4 ratio. Impact on the OHRQoL of a family was assessed using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). Dental caries, TDI, and malocclusion were diagnosed by three calibrated dentists (Kappa: 0.85-0.90). Data analysis involved descriptive statistics and conditional logistic regression analysis (p ≤ 0.05; 95%CI). There were no differences between the cases and controls regarding age, gender, and family income (p > 0.05). The most frequent responses on the B-ECOHIS among cases were "felt guilty" (68.6%) and "been upset" (48.2%). The following variables were significantly associated with negative impacts on family OHRQoL (cases): caries severity (OR = 6.680; 95%CI = 2.731-16.349), a history of toothache (OR = 2.666; 95%CI = 1.492-4.765), parental rating of the child's oral health as poor (OR: 1.973; 95%CI = 1.072-3.634), and parent's/caregiver's age (OR = 2.936; 95%CI = 1.077-3.478). Anterior open bite was positively associated with OHRQoL (OR = 4.050; 95%CI = 1.333-12.314). Caries severity, a history of toothache, parental rating of the child's oral health as poor, and younger parents/caregivers were associated with impact on the OHRQoL of the families of preschoolers.
