Superior lesion detection on 3D FSE T1WI with magnetization transfer and CHESS preparation pulses in children with focal epilepsy: Preliminary results.

In childhood drug-resistant focal epilepsy, the identification of a magnetic resonance imaging lesion significantly affects the management and prognosis, although it is often challenging. Herein we report the preliminary results of a modified MR sequence, in which both magnetization transfer and chemical shift selective preparation pulses are added to a 3D fast spin echo T1-weighted sequence to recognize focal cortical dysplasia. The scan time is short, and the images have expected uniform suppression of the background normal gray and white matter.

Effectiveness of training before unsedated MRI scans in young children: a randomized control trial.

Background: Young children requiring clinical magnetic resonance imaging (MRI) may be given general anesthesia. General anesthesia has potential side effects, is costly, and introduces logistical challenges. Thus, methods that allow children to undergo awake MRI scans are desirable.

Long-term durability of one-step adhesive-composite systems to enamel and dentin.

This study evaluated the long-term durability of three one-step adhesive-composite systems to ground enamel and dentin. Twenty-seven teeth were randomly divided into three groups of nine. The first group had its crowns sectioned to expose superficial dentin, which was then ground with 600 grit SiC paper.

Self-etching primers: is prophylactic pumicing necessary? A randomized clinical trial.

The purpose of this clinical trial was to determine whether pumice prophylaxis is required before the use of a self-etching primer (SEP). A total of 30 patients undergoing treatment with full upper and lower fixed appliances were recruited into this randomized cross-mouth controlled trial. In all cases, stainless steel orthodontic brackets were bonded using Transbondtrade mark XT adhesive after pretreatment of the enamel surface using a new SEP.
