ABSTRACT
BACKGROUND/AIMS: To compare the prevalence of positive bacterial cultures at the cesarean delivery (CD) incision site in patients with pre-operative application of chlorhexidine gluconate (CG) versus povidone iodine (PI). METHODS: Women undergoing a scheduled CD at ≥36 gestational weeks were randomly assigned to receive CG or PI. A swab of the incision site was performed at 3 min after disinfectant application and at 18 post-operative hours, and the prevalence of cultures with any detected bacterial growth was compared for the two groups. RESULTS: Of the 60 participants, 33 (55.0%) were in the PI group. There were no differences detected at 3 min, with 9.1% positive in the PI group versus 0% positive in the CG group (p = 0.2499). However, at 18 h, women in the PI group were seven times more likely than women in the CG group to have a positive culture (16/33 [48.5%] versus 3/27 [11.1%], OR = 7.53 [95% CI 1.67-38.83], p = 0.0023). Multivariate logistic regression demonstrated similar results: OR = 7.33 (95% CI 1.77-30.35), p = 0.0060. CONCLUSION: The prevalence of positive bacterial cultures obtained at the site of the skin incision 18 h after CD was higher in the PI versus the CG group.

A mordida cruzada anterior em forma de tesoura é uma forma rara de má oclusão e a sua correção deve ter início assim que for diagnosticada e, quando possível, o paciente entender o problema e colaborar com o tratamento ortodôntico. Este artigo ilustra o caso clínico de um paciente, sexo feminino, 8.9 anos de idade, Classe I esquelética, Classe II, divisão 1 de Angle, mordida cruzada anterior com o incisivo central superior esquerdo (21) em forma de tesoura, entre incisivo central inferior (31), e lateral do lado esquerdo (32), com recessão gengival no dente 31. A utilização do aparelho confeccionado em acrílico e parafuso expansor associado com mola digital anterior, mostrou-se eficaz para a correção desta má oclusão, favorecendo o estabelecimento de uma oclusão equilibrada. A dentição permanente se estabeleceu com boas relações oclusais e a paciente satisfeita com a estética dentária e facial
The scissor bite is a rare form of malocclusion and its correction must begin as soon as diagnosed, and when possible the patient should understand the problem and collaborate with the orthodontic treatment. This article presents a case report, a female patient, 8.9 years old, skeletal Class I, Class II, 1 division of Angle, anterior crossbite with the upper left central incisor (21) in a scissor bite position, between lower central incisor (31) and lateral left side (32), with gingival recession on tooth 31. The use of the expander screw and appliance confectioned in acrylic associated with a stainless steel spring was effective for the correction of the malocclusion, favoring the establishment of a balanced occlusion. The permanent dentition settled with a good occlusal relation and the patient was satisfied with the dental and facial aesthetics.
