ABSTRACT
AIM: This study aimed to investigate the associations between breastfeeding, nonnutritive sucking habits (NNSHs), and malocclusion in deciduous, mixed, and permanent dentition. MATERIALS AND METHODS: A sample of 50 children between 3 and 12 years, enrolled in a pediatric dentistry dental care program, underwent orthodontic examination for detection of occlusal patterns and malocclusion. In addition, data regarding breastfeeding duration and NNSH acquisition were obtained from standardized questionnaires responded by the children's parents or legal guardians. RESULTS: Regardless of a long period of breastfeeding, a high incidence of NNSH in the evaluated sample was observed. Nevertheless, the presence of NNSHs was not significantly associated with malocclusion. CONCLUSION: The findings could not indicate a statistically significant association between breastfeeding duration, acquisition of NNSHs, and malocclusion. Longitudinal studies with larger samples are still needed to better support clinical decisions.How to cite this article: Roscoe MG, da Silva Bonifacio SV, da Silva TB, Pingueiro JMS, Lemos MM, Feres MFN.

ABSTRACT
OBJECTIVE: this study aimed to evaluate the usefulness of current radiographic measurements, which were originally conceived to evaluate adenoid hypertrophy, as potential referral parameters. METHODS: children aged from 4 to 14 years, of both genders, who presented nasal obstruction complaints, were subjected to cavum radiography. Radiographic examinations (n = 120) were evaluated according to categorical and quantitative parameters, and data were compared to gold-standard videonasopharyngoscopic examination, regarding accuracy (sensitivity, negative predictive value, specificity, and positive predictive value). RESULTS: radiographic grading systems presented low sensitivity for the identification of patients with two-thirds choanal space obstruction. However, some of these parameters presented relatively high specificity rates when three-quarters adenoid obstruction was the threshold of interest. Amongst the quantitative variables, a mathematical model was found to be more suitable for identifying patients with more than two-thirds obstruction. CONCLUSION: this model was shown to be potentially useful as a screening tool to include patients with, at least, two-thirds adenoid obstruction. Moreover, one of the categorical parameters was demonstrated to be relatively more useful, as well as a potentially safer assessment tool to exclude patients with less than three-quarters obstruction, to be indicated for adenoidectomy. .
OBJETIVO: o objetivo deste estudo foi de investigar a utilidade de medidas radiográficas destinadas à avaliação da tonsila faríngea a serem utilizadas como potenciais parâmetros de encaminhamento. MÉTODOS: crianças de quatro a 14 anos, de ambos os gêneros, que apresentavam queixas referentes à obstrução nasal foram submetidas à radiografia do cavum. Os registros radiográficos (n = 120) foram avaliados de acordo com parâmetros categóricos e quantitativos, e dados resultantes foram comparados ao exame padrão-ouro de videonasofaringoscopia, em relação às suas taxas de acurácia (sensibilidade, valor preditivo negativo, especificidade e valor preditivo positivo). RESULTADOS: os parâmetros radiográficos categóricos apresentaram baixa sensibilidade para a identificação de pacientes portadores de 2/3 de obstrução do espaço coanal. No entanto, alguns destes parâmetros apresentaram especificidades relativamente altas quando 3/4 de obstrução coanal era o ponto de corte de interesse. Dentre as variáveis quantitativas, um modelo matemático se mostrou mais adequado para identificar pacientes com mais de 2/3 de obstrução coanal. CONCLUSÃO: este modelo demonstrou, assim, ser potencialmente útil como método de rastreamento para identificação de pacientes com pelo menos 2/3 de obstrução adenoidiana. Além disso, um dos parâmetros categóricos analisados demonstrou ser relativamente mais útil e potencialmente seguro para eliminar pacientes queixosos com menos de 3/4 de obstrução a serem indicados à adenoidectomia. .
