A prospective clinical trial was conducted to determine the cephalometric and occlusal changes following maxillary expansion and protraction. Twenty Southern Chinese patients (eight males and 12 females with a mean age of 8.4 +/- 1.8 years) with skeletal Class III malocclusions were treated consecutively with maxillary expansion and a protraction facemask.(More)
It is generally believed that component-based software development leads to improved application quality, maintainability and reliability. However, most software reliability techniques model integrated systems. These models disregard system's internal structure, taking into account only the failure data and interactions with the environment. We propose a(More)
In a study to compare the clinical diagnostic skills of academic general pediatricians and academic pediatric cardiologists in the evaluation of heart murmurs, a total of 128 patients (aged 1 month to 18 years) newly referred to a university pediatric cardiology clinic were evaluated by one of three general pediatricians and one of four pediatric(More)
INTRODUCTION A self-etching primer (SEP) saves valuable time by eliminating the many steps required to etch, rinse, and place a sealant before application of the adhesive and placement of the bracket. The purpose of this study was to compare the effects of a conventional etch and sealant (CES) and a SEP on enamel decalcification in vivo. METHODS(More)
We evaluated associations between dust exposure, demographic factors, and lung function by longitudinal and cross-sectional analyses in 475 steelworkers who participated in at least three spirometry tests over 5 yr between 1982 and 1991. Baseline and follow-up spirometry and changes between baseline and final follow-up assessment attributable to age,(More)
The objectives of this study were (1) to compare the in vivo survival rates of orthodontic brackets bonded with a resin-modified glass ionomer adhesive (Fuji Ortho LC; GC America, Alsip, Ill) after conditioning with 10% polyacrylic acid and a conventional resin adhesive (Light Bond; Reliance Orthodontic Products, Itasca, Ill) bonded with 37% phosphoric(More)
BACKGROUND The objective of this study was to select a model of cephalometric variables to predict future Class III growth patterns based on the results of early orthopedic treatment with a protraction facemask. MATERIAL Sixty-four patients with Class III malocclusion were treated with a protraction facemask. Cephalometric radiographs were taken before(More)
PURPOSE This research was conducted to develop a valid, reliable, quick, and nonstigmatizing tool for assessing literacy in the healthcare setting. METHODS The Literacy Assessment for Diabetes (LAD) instrument was developed as a word recognition test composed of 3 graded word lists in ascending difficulty. This literacy test, which was specific to(More)
INTRODUCTION A shortage of healthcare providers in West Virginia led to the creation of a statewide, community-based program with a required three-month rural experience for most state-sponsored health professions students. Project description: Initiated using funding from the W. K. Kellogg Foundation and expanded using both state funds and Area Health(More)
The purpose of this study was to compare the debonding force of orthodontic brackets bonded with two conventional resin adhesives (Resilience L3 and Light Bond) and a resin-reinforced glass ionomer cement (Fuji Ortho LC). For the in vitro part of the study, 80 extracted premolars were randomly divided into four groups. In groups A and B, brackets were(More)
