RESUMEN

INTRODUCTION: Various types of separators have been advocated, but the ideal separator should produce optimum separation with minimal pain and discomfort. OBJECTIVE: The objective of this study was to evaluate and compare the amount of separation achieved by three different types of separators (Elastomeric, Kesling and Kansal), and to assess the associated pain and discomfort. METHODS: A random single-blind split-mouth study was conducted on 108 patients seeking fixed orthodontic treatment, in which two different separators were used on each side in both the arches for a single patient. After five days, the amount of separation was measured with a feeler gauge. Visual Analogue Scale (VAS) scoring was performed by the patient on each day, to evaluate pain perception. Discomfort was evaluated by questionnaire filled by the patient at the time of separator removal. RESULTS: The greatest amount of separation was seen with the elastomeric separators, while the smallest separation was seen with Kansal separators. VAS scoring showed maximum pain at day 1 with all the three separator types. Highest pain was perceived in the Elastomeric separators group, followed by Kesling and Kansal separators, respectively. Statistically significant difference was found in VAS score of Elastomeric separators, when compared to both Kesling and Kansal, on day 1 and 2 (p= 0.001). Analysis of the questionnaires revealed that a greater number of patients experienced discomfort with elastomeric separators placement (69.4%), which was statistically significant (p< 0.01) when compared to the other two types of separators. Answers to the other questions were comparable, except for the need for medications, which was reportedly highest with elastomeric separators. CONCLUSION: Kesling separators produce adequate separation with minimal discomfort and pain, compared to Elastomeric and Kansal separators.

Resumo Introdução: diversos tipos de separadores de dentes já foram descritos e seu uso, justificado na literatura. Porém, o separador ideal deve produzir uma força adequada para realizar a separação com o mínimo de dor e desconforto. Objetivo: o objetivo do presente estudo foi avaliar e comparar a separação ortodôntica obtida por meio de três diferentes tipos de separadores (Elastômeros, Kesling e Kansal), bem como a dor e o desconforto a eles vinculados. Métodos: foi conduzido um estudo randomizado, cego e de boca dividida em 108 pacientes interessados em realizar tratamento ortodôntico, nos quais foram utilizados dois separadores diferentes, um em cada lado de ambas as arcadas de cada paciente. Cinco dias após a inserção dos dispositivos, a quantidade de separação foi mensurada com o auxílio de um medidor (calibrador de folga). Para avaliar a dor, os pacientes preencheram uma Escala Visual Analógica (EVA) a cada dia do estudo; e, para a avaliação do desconforto, preencheram um questionário no dia da remoção dos separadores. Resultados: os Elastômeros obtiveram a maior quantidade de separação, enquanto os separadores Kansal conseguiram a menor separação. A análise das EVAs apontou a maior intensidade de dor no primeiro dia, para os três tipos de separadores, sendo os maiores índices relatados no grupo de Elastômeros, seguido pelos grupos Kesling e Kansal, respectivamente. Diferenças estatisticamente significativas foram encontradas nas escalas EVA dos Elastômeros em comparação aos separadores Kesling e Kandal, nos dias 1 e 2 (p= 0,001). A análise dos questionários mostrou que um grande número de pacientes relatou desconforto após a inserção dos Elastômeros (69,4%), valor estatisticamente significativo em comparação aos outros dois tipos de separadores (p< 0,01). As respostas às outras questões foram semelhantes entre os grupos, com exceção da necessidade de uso de medicamentos, a qual foi maior no grupo dos Elastômeros. Conclusão: os separadores Kesling produziram uma separação adequada, com o mínimo de dor e desconforto, em comparação aos Elastômeros e separadores Kansal.

RESUMEN

INTRODUCTION: Alexander disease is a disorder caused by a mutation and accumulation of the glial fibrillary acidic protein. Currently, three subtypes are acknowledged: an infantile, a juvenile, and an adult form. However, onset early in infancy or in the prenatal period has been shown to present with a uniform pattern of symptoms-suggesting the presence of a distinct neonatal form of the disease. RESULTS AND DISCUSSION: Though the neonatal form of Alexander disease is not well acknowledged, a uniform and distinct presentation of the disease in neonates has been observed, suggesting the need for a different course of identification and treatment. Clinical presentation of the neonatal form is distinguished by leukodystrophy and generalized, frequent, and intractable seizures. While the infantile form presents with ataxia, hyperreflexia, and other upper motor neuron symptoms, none of these has been observed in the neonatal form. In the diagnosis of neonatal Alexander disease, it is essential to rule out other causes of leukodystrophy and the presence of neoplasms.
