VILTRES PEDRAZA., Guadalupe Rita et al. Risk factors associated with the loss of dental arch length in children. Multimed [online]. 2020, vol.24, n.5, pp.1183-1196.  Epub 17-Set-2020. ISSN 1028-4818.

The teeth are maintained in correct relation due to a series of forces that constitute the dental balance, if one of these forces is altered, changes are made in relation to the adjacent teeth, causing a space problem in the dental arches. The objective was to identify the risk factors associated with the loss of dental arch length in children. A descriptive cross-sectional observational study was conducted in children of the "Frank País" Primary School belonging to the health area of the “Manuel Cedeño” University Clinic of Stomatological Specialties, between January 2018 and February 2019. The universe was 160 patients who complied with the inclusion criteria. The premature loss of temporary teeth was presented as a risk factor that led to the loss of the length of the dental arch in 75,62 % of the children studied, followed by proximal dental caries (70,62 %), digital suction habit (74,37 %) and abnormality of the buccal musculature (61,25 %); the group of 7-9 years was the most affected. It is concluded that there is a relationship between premature loss of temporary teeth, proximal dental caries, digital suction and abnormality of the buccal musculature as risk factors for the loss of dental arch length in children.
