MENDOZA, Pedro et al. Prevalence of non-nutritive sucking habits and their relationship with malocclusion and dentomaxillary abnormalities in preschoolers of Cnel. Oviedo, Paraguay. Mem. Inst. Investig. Cienc. Salud [online]. 2019, vol.17, n.3, pp.49-54. ISSN 1812-9528.

The objective was to determine the prevalence of non-nutritive suction habits and their relationship with malocclusions and dentomaxillary anomalies in preschool children of Coronel Oviedo - Paraguay, during 2015. An observational, descriptive cross-sectional study with analytical component was carried out, with two-stage stratified probabilistic sampling. The study population consisted of boys and girls of the Pre-Primary Education (nursery, kindergarten and pre-school). The variables of the study were the non-nutritive suction (digital suction and suction of the pacifier, age, sex, onychophagia and the use of the feeding bottle). The data were collected through a survey addressed to the parents, accompanied by an oral inspection. Three hundred forty-four schoolchildren were included, 48.84% (168) was 5 years old and 52.91% (182) was male. Of the total, 13.08% (45) performed digital suction, 9.59% (33) pacifier suction and 38.95% (134) other habits. By differentiating the presence of habits with demographic characteristics, it was seen how the presence of digital suction was related to the open bite (p=0.000), the crossbite (p = 0.049), and the orientation of the incisors (p=0.000). ), the shape of the arch (p = 0.000), the cross sectional occlusion (p=0.046) and the sagittal occlusion (p = 0.000). The prevalence of non-nutritive suction habits in these school children was high and related to malocclusion and the appearance of dentomaxillary anomalies, so the education of parents for the prevention of these conditions is fundamental.
