BACKGROUND Numerous strategies have been proposed to decrease the treatment time a patient requires in orthodontic treatment. Recently, a number of device-accelerated therapies have emerged in orthodontics. Photobiomodulation is an emerging area of science that has clinical applications in a number of human biological processes. The aim of this study was to(More)
Numerous experimental studies and clinical anecdotal evidence demonstrate a close interaction between masticatory muscle function and skeletal form. The purpose of this study was to determine whether a relationship existed between histochemical characteristics of human masseter and medial pterygoid muscles and cephalometric measurements of the 11 subjects(More)
A device using enzyme immunochromatography to indicate visually theophylline concentration in a small capillary blood sample was evaluated for precision and accuracy at four hospitals. Preliminary studies indicated sensitivity as low as 2.5 micrograms/ml, and accuracy and precision matched those in test samples ranging from 5 to 30 micrograms/ml. Absence of(More)
In reviewing the literature relative to the development of Class II malocclusions, it can be learned that "not every Class II is a Class II." We must remember that behind the soft tissue drape of the patient's face is a totally dynamic process that can be influenced by our heritage and altered by our environment. We realize when performing an occlusal(More)
