RODRIGUEZ, Patricia N et al. Association among salivary flow rate, caries risk and nutritional status in pre-schoolers. Acta odontol. latinoam. [online]. 2015, vol.28, n.2, pp.185-191. ISSN 1852-4834.

Modeer T. et al.(2011) claim that there is association between decreased salivary flow rate and caries in obese adolescents. The aim of this study was to determine the association among nutritional status, salivary flow rate and caries risk in preschoolers. The study comprised 60 children aged 3 to 6 years attending kindergartens in areas immediately adjacent to Buenos Aires City, Argentina. Body weight and height of the children were determined. Body mass index was calculated and the population was classified anthropometrically according to the WHO 2007 (WHO Anthro. Program). Caries risk was determined. Saliva was collected in sterile graduated widemouth containers, without stimulation and without food restrictions. Salivary flow rate (SFR) was determined. Statistical analysis was performed using Pearson's test. It was found that 56.7% (IC95%: 37.7-74.0) of anthropometrically adequate children (Ad) and 37.0% (IC95%: 20.1-57.5) of overweight and obese children (OW/Ob) had caries. The odds ratio for caries (OR=3.78; IC95%: 1.2-11.8, p=0.02) was almost 4 times higher in adequate children than in the others. SFR was 0.534 0.318 ml/min in Ad and 0.439 } 0.234 ml/min in OW/Ob. Pearson's test showed no correlation between SFR and nutritional status (r= 0.004592, p= 0.5977). Although the presence of caries was lower in overweight and obese children, no correlation was found between nutritional status and salivary flow rate.
