Low birth weight and the delay on the eruption of deciduous teething in children

Abstract

Objectives: To analyze the association between low birth weight (LBW) and the occurrence of the delay on the eruption of deciduous teething (DEDT) in children from 04 to 30 months, living in Salvador, Bahia. Methods: A cross-sectional study involved 520 children at four to thirty months of age, from public, private and philanthropic daycares from two districts in Salvador. A descriptive analysis and unconditional logistic regression were done to estimate the odds ratios (ORs), using the Confidence Interval of 95% as a criterion for accepting associations. Poisson regression was used as an analytical strategy to obtain the prevalence ratio. Results: the prevalence of the delay on the eruption was 10.29%. There was a positive association between LBW and occurrence of DEDT among children with less than 24 months, both in the unadjusted model (PR=2.07, 95%CI= 0.96 4.44) as in the adjusted (adjusted PR=2, 27, 95%CI= 1.02 5.07). Conclusions: the variables of development and nutritional at birth and during the early life may be important predictors of the chronology of eruption. Further investigations should be carried out towards the adequate evaluation of the LBW role in the occurrence of the delay on the eruption.

Is Low Birth Weight a Risk Factor for Early Childhood Caries? : A Nationwide Retrospective Cohort

“…The authors presumed that LBW may contribute to delayed teething because nutritional factors influence odontogenesis and teeth eruption. 21 Our results that infants with NBW were at a greater risk for ECC than those with LBW may be attributable to the delayed teething caused by LBW and the consequent delay in intraoral exposure. Moreover, a systematic review of studies on the relation of ECC and body mass index as an indicator of the body weight status reported that overweight children were at a higher risk for ECC than normal weight/underweight children, which supports our results that ECC is less likely to occur among LBW infants than among NBW infants.…”

Nutritional Status is Associated with Permanent Tooth Eruption in a Group of Brazilian School Children

“… 10 - 25 Although the association between permanent tooth eruption (or delayed exfoliation of the primary tooth) was previously investigated in other Brazilian populations, 19 , 20 we also decided to explore the impact of the nutritional status on tooth eruption time in School children from Alfenas, which is a medium size city located in Minas Gerais state. It is important to emphasize that Brazil is a country with a continental size with a different ethnic composition ranging according to the state, 2 as well as socioeconomic and cultural differences. The influence of ethnicity 8 and socioeconomic aspects 9 on tooth eruption have already been documented and suggested.…”

“…Many factors could affect primary and permanent tooth eruption. Some studies suggested that low birth weight and prematurity, 1 - 4 endocrinology conditions, 5 - 7 ethnicity, 8 socioeconomic aspects, 9 and nutritional status, such as malnourishment (underweight), and obesity, 7 , 10 - 25 could affect tooth eruption leading to a delay or earlier tooth eruption and primary tooth exfoliation.…”

Path Analysis of the Relationships between the Eruption Time of the First Primary Teeth and Various Factors in Twins

“…According to the literature, the eruption timing of primary teeth is genetically determined. However, perinatal maternal circumstances, early childhood metabolic, systemic, and nutritional factors, such as the type of feeding, socioeconomic variables, and ethnicity are also all linked to primary tooth eruptive timing [ 2 , 3 , 5 , 6 , 7 , 8 , 9 ]. The effect of gender differences on the eruption times of primary teeth has not been clearly determined.…”

“…Birth weight is an indicator of perinatal factors, and it has been reported in the literature that birth weight is associated with age at the eruption of primary teeth [ 2 , 4 , 12 ]. There is a positive correlation between late eruption and low birth weight due to the general developmental delay in these children [ 9 ]. This supports the assumption that malnourished children in the prenatal period, when teeth are just beginning to form, suffer from nutritional problems that can negatively impact the development of their primary teeth [ 1 , 9 ].…”
