Objective: This work aims to determine prevalence and consequences of Molar Incisor Hypomineralization in the city of Ouro Verde – SP. Methodology: 457 children, students from the municipal school EMEF Julia Roseira Jerônimo were examined, aging from 7 to 11 years old. Clinical examinations for the diagnosis were performed by a single trained and calibrated examiner using the criteria proposed by the European Academy of Pediatric Dentistry (EAPD, 2009) using natural light and wood spathulas. Result: The index found in the city was 15% of students (79 affected children) and only one case with sensitivity. Conclusion: prevalence was significative, although symptoms related were rare.

The tongue trust and anterior projection through the dental arcades during swallowing is known as Adapted Swallowing (AS) and is a common finding during mixed dentition. The authors studied the morphologic dentofacial characteristics through cephalometric measures in 38 girls and 35 boys, aged seven to nine years, presenting AS, as determined by the speech therapist evaluation. Cephalometric evaluation was obtained by Radiocef 2.0 software. The measurements studied were the mandibular and maxillary relations to the cranial base, the nasolabial angle, and the upper airway patency, as proposed by McNamara Jr (1984), and the convexity and facial axis angles and maxillary height from Ricketts (1960; 1981). Results, analyzed in relation to sex and racial group, showed an association of Class II facial convexity with the African Brazilian children with dark black skin. This classification does not reflect an abnormality as all African Brazilians studied were classified as class II, due to the fact that the standard measurements are based in the white American population. These findings point to the need of specific racial normative standard for evaluating orofacial and dental structures.
