Association Between Mothers And Infants' Risk Of Dental Caries

Objective: This aim of this study is to assess the influence of mothers' different socio-demographic background,their own oral health habits,feeding habits and oral health status on their one-month infant's risk of dental caries,and provide a theoretical basis for the prevention of early childhood caries.Methods: One-month infants and their mothers from Huangpu maternal and child care service centers in Shanghai were involved in the study.Information on mothers' socio-demographic background,their own oral health habits,and feeding habits were collected using questionnaires.Clinical examination included mothers' dental caries,visible plaque index(VPI)and bleeding on probing(BOP).Plaque samples of mothers and their infants were also collected to assess their level of risk on dental caries.Result: A total of 165one-month infants and their mothers participated this study.10.3% of one-month infants were in the high risk of dental caries.DMFS of mothers ranged from 0 to 26 with a mean of 2.7(±3.9).Mean value of VPI and BOP were 0.42(±0.19)and 0.14(±0.15).41.9% ofmothers were in the high risk of dental caries.The result of the multiple factor Logistic analyses indicated that the infants who was born underweight(OR=6.5,95% CI=1.5-29.3),were feed with nursing bottle more than 5 times every day(OR=5.1,95%CI=1.3-19.5),and their mothers who have more than 25% of site with bleeding(OR=4.7,95%CI=1.3-16.8)were in the high risk of dental caries.No other socio-demographic background,oral health habits,and feeding habits were significantly associated with one-month infants' risk of caries(p>0.05).Conclusions : They were 10% of one-month infants have high risk of caries.Underweight when they were born,frequency of feeding with nursing bottles and mothers with serious gingivitis were associated with one-month infants' risk of caries.
