The midazolam technique has been used in pediatric patients with fear or anxiety to obtain relaxation and to modify negative conduct. The objective of this study was to evaluate if hydroxyzine, an antihistaminic depressor of the central nervous system, added to midazolam technique by oral dosage provides more suitable levels of sedation. 24 children between 2 to 6 years of age, ASA I, with negative conduct (Frankl scale II) were distributed and randomized in two groups; the first group (I) received midazolam 0,75 mg/kg of weight; and the second group (II) received midazolam 0,75 mg/kg of weight plus hydroxyzine 1 mg/kg of weight. It was observed sedation level in the scale of Houpt, and vital signs were checked throughout the treatment. The results showed that: in group I, 58,3% obtained very good to excellent, sedation levels, 33,3% good to regular sedation levels and 8,3% poor sedation...

The purpose of this study was to evaluate the solubility of gutta-percha in three solvents used in endodontics: xylol of traditional use, and the essential oils: eucalyptol and orange oil, of recent use, given the frequent need to remove the obturation material in radicular retreatment procedures. One hundred twenty samples of gutta-percha were prepared in a standardized way in small cylinders, being divided equally into four groups for immersion in three experimental solvents and distilled water (control group) during 2.5 and 10 minutes at room temperature. The solvent effect was recorded in grams of weight loss, calculating the difference between pre and post-immersion samples weight for each experimental time. The results were analyzed and compared by Tukey test (p <0.05). Under the conditions of this study it is concluded that, all experimental solvents were effective to dissolve ...
