Tratamento de má oclusão de Classe III subdivisão com mordida cruzada posterior unilateral através da técnica multiloop edgewise archwire (MEAW) ­ relato de caso / Treatment of Class III subdivision malocclusion with unilateral posterior crossbite through multiloop edgewise archwire (MEAW) technique ­ case report

Resumo O objetivo deste trabalho foi relatar um caso clínico de tratamento de má oclusão de Classe III subdivisão com mordida cruzada posterior unilateral através da técnica Multiloop Edgewise Archwire (MEAW). O paciente do sexo masculino, 19 anos de idade, relatou o prognatismo mandibular como queixa principal. Apresentava má oclusão de Classe III de Angle, mordida cruzada posterior unilateral direita, mordida de topo na região anterior, linhas médias não coincidentes e assimetria facial. Devido à recusa ao tratamento cirúrgico pelo paciente, foi proposto uma compensação ortodôntica dentoalveolar. Foi utilizada a técnica MEAW associada ao uso de elásticos intermaxilares 3/16". Ao final do tratamento, foi obtida relação oclusal de Classe I entre caninos e molares, correção da mordida cruzada posterior unilateral, coincidência entre as linhas médias. A técnica MEAW mostrou eficácia na correção da má oclusão de Classe III subdivisão e mordida cruzada posterior unilateral. (AU)

Abstract The aim of this study was to report a clinical case of treatment of Class III subdivision malocclusion with unilateral posterior crossbite using the Multiloop Edgewise Archwire (MEAW) technique. A 19-year-old male patient reported mandibular prognathism as the main complaint. He had Angle Class III malocclusion, unilateral posterior crossbite on the right side, top bite in the anterior region, non-coincident midlines and facial asymmetry. Due to the patients refusal of surgical treatment, dentoalveolar orthodontic compensation was proposed. The MEAW technique associated with 3/16" intermaxillary elastics were used. At the end of the treatment, a Class I occlusal relationship between canines and molars, correction of the unilateral posterior crossbite and coincidence between the midlines was obtained. The MEAW technique was effective in correcting Class III subdivision malocclusion and unilateral posterior crossbite. (AU)

Association between early childhood caries and maternal caries status: A cross-section study in São Luís, Maranhão, Brazil.

OBJECTIVE: This study aims to evaluate the association between early childhood caries (ECC) and maternal caries status, and the maternal perception of ECC risk factors. MATERIALS AND METHODS: A cross-sectional study was carried out with 77 mother-child pairs, the children ranging from 12 to 36 months of age and their mothers, who were seeking dental care at a health center in São Luís, Maranhão, Brazil. Data collection was conducted using a specific questionnaire for mothers. Oral clinical examination of the mother-child binomial to assess caries incidence, gingival bleeding (GB) and visible plaque was done. Home visits were performed in 10% of the sample in order to observe the environmental conditions, dietary habits and dental hygiene practices. RESULTS: The findings showed that the caries prevalence in children was 22.5 times higher in the mother who had decayed tooth (prevalence ratio [PR] = 22.5, confidence interval [CI] 95% = 3.2-156.6, P < 0.001). GB also was observed in 14 mothers and children, the PR in pair was 12.2 (CI95% = 1.6-88.9, P < 0.001). The variables are related for the mother-child binomial in regression linear analysis. CONCLUSION: The maternal caries status was associated with ECC.
