ABSTRACT
OBJECTIVES: The aim of this study was to evaluate the effects of tri-antibiotic paste (TAP) on microtensile bond strengths (MTBS) of dental adhesives to dentin. MATERIALS AND METHODS: Sixty extracted molars had their occlusal surfaces flattened to expose dentin. They were divided into two groups, i.e., control group with no dentin treatment and experimental group with dentin treatment with TAP. After 10 days, specimens were bonded using self-etch (Filtek P90 adhesive) or etch-and-rinse (Adper Single Bond Plus) adhesives and restored with composite resin. Teeth were sectioned into beams, and the specimens were subjected to MTBS test. Data were analyzed using two-way ANOVA and post hoc Tukey tests. RESULTS: There was a statistically significant interaction between dentin treatment and adhesive on MTBS to coronal dentin (p = 0.003). Despite a trend towards worse MTBS being noticed in the experimental groups, TAP application showed no significant effect on MTBS (p = 0.064). CONCLUSIONS: The etch-and-rinse adhesive Adper Single Bond Plus presented higher mean bond strengths than the self-etch adhesive Filtek P90, irrespective of the group. The superior bond performance for Adper Single Bond when compared to Filtek P90 adhesive was confirmed by a fewer number of adhesive failures. The influence of TAP in bond strength is insignificant.

El dolor lumbar es una enfermedad frecuente, es la principal causa de limitación física en personas menores de 45 años y constituye el séptimo motivo de consulta médica en la atención primaria, y a pesar de su carácter benigno, es una de las primeras causas de invalidez en los países desarrollados. El propósito de este estudio fue revalidar la vigencia del empleo de los ejercicios en el tratamiento rehabilitador del síndrome doloroso lumbar. La realización de ejercicios, han demostrado ser efectivos para mejorar el dolor y la limitación física que ocasiona en los pacientes el dolor de espalda con dolor, tradicionalmente, para el tratamiento rehabilitador de las enfermedades de la columna vertebral, se indican los ejercicios de Williams y la técnica vertebral de Charriere, que a pesar de su uso cotidiano, persisten confusión en diversos aspectos en cuanto a su técnica de aplicación, e incluso en muchos libros y artículos tienden a mezclarlos indistintamente. Se delinean de cada técnica sus objetivos generales, tipos de ejercicios, posiciones básicas, regiones de la columna vertebral donde se pueden aplicar, y fase de la enfermedad donde se recomienda su uso. Se describe la posición de Williams y sus seis ejercicios básicos, según su propósito. Estas técnicas mantienen reconocida eficacia en el tratamiento rehabilitador de las dolencias de la columna vertebral.
Back pain is a common disease. It is the leading cause of physical limitation in people younger than 45 years and it is the seventh reason for consultation in primary care. Despite its benign nature, it is one of the leading causes of disability in developed countries. The purpose of this study was to validate the effectiveness of the use of rehabilitation exercises in the treatment of lumbar pain syndrome. The practice of exercises has proven to be effective for improving pain and physical limitations that brings in back pain patients. Traditionally, Williams exercises and Charriere spinal technique are indicated for the rehabilitation treatment of the spine diseases. Despite daily use, confusion persists in various aspects regarding application technique, and many books and articles tend to mix them interchangeably. Each technique is outlined concerning their overall objectives, types of exercises, basic positions, regions of the spine which can be applied, and stage of disease where their use is recommended. Position of Williams and its six basic exercises by purpose are here described. These techniques remain known efficacy in rehabilitation treatment for ailments of the spine.
La douleur lombaire est une affection fréquente. Elle provoque des limitations physiques chez les personnes de moins de 45 ans, et constitue la septième cause de consultation médicale aux soins primaires de santé. Malgré son caractère bénin, elle est l’une des premières causes d’invalidité dans les pays développés. Le but de ce travail est de revalider l’emploi des exercices dans le traitement de rééducation du syndrome douloureux lombaire. Les exercices ont montré être effectifs contre la douleur et la limitation physique provoquées par les maux de dos chez les patients. Dans le traitement de rééducation des maladies du rachis, on indique les exercices de Williams et la technique de manipulation vertébrale de Charrière qui, malgré leur usage quotidien, entraînent une confusion dans différents aspects tels que leur technique d’application, et même dans plusieurs livres et articles il y a une tendance à les mêler indistinctement. On décrit les objectifs généraux de chaque technique, les types d’exercices, les positions fondamentales, quelles régions de la colonne vertébrale ils peuvent être appliqués, dans quelle étape de la maladie ils sont conseillés d’être utilisés. On décrit la position de Williams et ses six exercices fondamentaux, selon leur fin. Ces techniques maintiennent une renommée efficacité dans le traitement de rééducation des affections du rachis.
