Abstract:

OCHOA RAMIREZ, Evelyn Daniela et al. Occlusion in children with mixed dentition, facial pattern study and type of occlusion in Ecuador. Odontología Vital [online]. 2019, n. 30, pp. 15-20. ISSN 1659-0775. Objective: Define facial morphology and sagittal association in children with mixed dentition. Materials and methods: Descriptive, observational and cross-sectional study of 100 students aged 6 to 12 years. The clinical evaluation of the facial profile of the occlusion was made through extraoral and intraoral photographs and study models by two examining evaluators with a reliability in their diagnostic criteria, considering the Capelozza criteria. Results: A close relationship was found between the facial pattern with the molar and canine class. Except pattern II, in which there was correlation with class II molar, but not with canine class II. The heterogeneity in the distribution of the classes of pattern I was evidenced. In class II, the classes were more homogeneous with more than 70% of class II individuals in their molar relationship. The Pearson Chi Square test determined ap= 0.678 when considering the canine relationship on both sides. Conclusions: The study revealed prevalence of canine class I deciduous in both genders. Class I and II molar permanent in equal proportions in both genders. With regard to age, those between 6 and 10 years were more tending to class II molar.
