MARTIN MORENO, V.; MOLINA CABRERIZO, Mª R.    GOMEZ GOMEZ, C.. Relationship among the eruption of the first temporal teeths, the breast feeding duration and the anthropometric development in the first two years of life. []. , 21, 3, pp.362-368. ISSN 1699-5198.

Background: The anthropometric development in the first two years of life can be influenced by diverse factors, being analyzed in this study the implication of the primary tooth eruption and the breast feeding duration in this development. Methods: Longitudinal study. 141 healthy children participated (67 boys and 74 girls), being analyzed the association among the duration of breast feeding, the number of teeth present at the 6, 7, 9 and 12 months, the anthropometrics parameters weight, height and body mass index (BMI) to the birth, 1-7, 9, 12, 15, 18 and 24 months and the growth rate. Results: The weight and height at the birth or the duration of breast feeding didn't associate significantly with the weight and height at the 2 years or the number of teeth at 6, 7, 9 or 12 months, but the women with more weight (r= 0,366) and height (r = 0,377) at month of life have a bigger number of teeth at 9 months (p = 0,001). In both sexes,the number of teeth at the 9 months are associated significantly with the weight (boys r = 0,328, p = 0,01; girls r =0,307, p = 0,011) and height (r = 0,352 boys and girls p =0,005) at two years. Conclusions: In healthy children the duration of maternal nursing doesn't influence in the degree of anthropometric development reached at 2 years, but yes makes it the number of teeth present at 9 months, result that suggests that the eruption dental early could suppose an evolutive advantage.
