“…Other studies demonstrating the association between breastfeeding over 18 months and increased caries risk did not adjust for confounders [Yonezu et al, 2006;Prakasha Shrutha et al, 2013;Nobile et al, 2014]. Our analysis, adjusted for confounders, did not observe an association between prolonged full or any breastfeeding for >12 months and increased caries risk ( tables 4 , 5 ).…”

“…An increased risk of dental caries associated with prolonged breastfeeding has been reported in several studies [Yonezu et al, 2006;Saraiva et al, 2007;Feldens et al, 2012;Prakasha Shrutha et al, 2013;Chaffee et al, 2014;Hong et al, 2014a;Nobile et al, 2014;Jain et al, 2015;Kato et al, 2015]. Compared to cow's milk, human milk presents more cariogenic properties responsible for dental caries, because it contains more carbohydrates but less calcium, phosphorus, and protein [Erickson and Mazhari, 1999;Bowen and Lawrence, 2005].…”

Breastfeeding Duration and Childhood Caries: A Cohort Study

This cohort study was conducted in Khon Kaen, Thailand, to test the hypothesis that a longer breastfeeding duration increases the risk for dental caries in primary teeth. We collected information on infant feeding practices and potential confounders using a structured questionnaire to interview mothers or caregivers during the second trimester of pregnancy and after birth at 21 days and at 3, 12, 18, 24, and 36 months. Regardless of other liquids and foods, full breastfeeding was defined as feeding breast milk but not formula, while any breastfeeding was feeding breast milk with or without formula. Two calibrated dentists measured dental caries when the children were 3-4 years of age using the decayed, missing, and filled surfaces (dmfs) index following the World Health Organization criteria. Negative binomial regression with a generalized linear model was used to estimate relative risks (RRs) and 95% confidence intervals (CIs) using dmfs as an outcome. Log-binomial regression was performed to model the caries prevalence. Of 556 children, 88.1% had dental caries with a mean dmfs of 14.2. Full breastfeeding for 6-11 months was significantly associated with a lower dmfs (adjusted RR 0.77, 95% CI 0.63, 0.93) and a lower caries prevalence (adjusted RR 0.45, 95% CI 0.22, 0.90). The frequency of sleeping while breast- or bottle-feeding increased the caries risk in a dose-response manner. There was no association between duration of any breastfeeding and dental caries. In conclusion, full breastfeeding for 6-11 months may protect against dental caries in primary teeth. Prolonged breastfeeding was not associated with dental caries in this population.

“…We also found that children breast-fed at 18 months of age were several times more likely to have dental caries at 2 years of age than prolonged bottle-fed children 20) . However, this study did not answer the question of why prolonged breast-feeding was correlated with more dental caries.…”

The aim of this study was to investigate the characteristics and risk factors of prolonged breast-feeding in children. A total of 105 children aged 18 months were screened for ongoing breast-feeding at a public health center. Of these, 105 children were selected for a more comprehensive examination, involving investigation of dietary, tooth-brushing habits and oral hygiene. The children were examined again, and initial and manifest caries were recorded at 24 months of age. As a result, 20 (19.0%) of the 105 children had caries at 24 months of age. Logistic regression analysis revealed an association between caries and bedtime breast-feeding (p‫.)300.0ס‬ Oral hygiene at 18 months of age was also correlated with caries (p‫.)510.0ס‬ It was concluded that reducing the frequency of feeding, early establishment of good oral hygiene habits and also regular visits to the dentist are essential in preventing nursing caries in prolonged breast-fed children.

“…On the other hand, a recent animal study 2) has suggested that high frequency exposure to human breast milk is more cariogenic than that to bovine milk, probably because human breast milk contains a higher concentration of lactose. The results of an earlier study by our group 21) showed that children who continued to breastfeed at the 14) . Earlier study by our group found that children who developed caries before 18 months of age exhibited high caries progression up to 3 years of age 19,20) .…”

The purpose of this study was to investigate the relationship between interdental spacing in the upper incisors and other associated factors with colonization by Streptococcus mutans in children. A total of 47 children aged between 24 and 36 months with no decayed cavities were enrolled in the study. Models were obtained to evaluate interdental spacing in the upper anterior region. The relationships between S. mutans colonization and number of erupted teeth, interdental spacing, diet, and oral hygiene behavior were investigated. S. mutans was detected in the saliva of 14 children (29.8%). No sociodemographic variable was associated with colonization by S. mutans. Neither number of erupted teeth nor children's age showed an influence on colonization by S. mutans. However, children with interdental spacing in the upper incisors were less likely to show colonization by S. mutans (15.8%) than those without (39.3%). Furthermore, children who ceased breastand/or bottle-feeding by 15 months of age were less likely to show colonization by S. mutans (22.7%) than those who continued feeding until 19 months of age or more (46.2%).
