OBJECTIVE To investigate the distribution patterns of primary and permanent teeth in the cleft area and the numerical variation in teeth in unilateral complete cleft lip and palate (UCLP) patients. DESIGN A survey of the dentition in UCLP patients. SETTING Craniofacial Center, Chang Gung Memorial Hospital, Taipei, Taiwan. PATIENTS 137 UCLP patients(More)
Five hundred and forty-three Chinese patients in the primary dentition stage were evaluated for mesiodens with maxillary, anterior occlusal films. Compared with other studies, a higher prevalence was found, using different age-groups and diagnostic methods. The distributions of mesiodens by sex, location, and direction were also studied. Because mesiodens(More)
INTRODUCTION The precise role of irregular ventricular response in atrial fibrillation (AF) has not been fully elucidated. This study examined the independent effects of rhythm regularity in patients with chronic AF. METHODS AND RESULTS This study included 50 patients who had chronic lone AF and a normal ventricular rate. Among these patients, 21 who(More)
BACKGROUND The purpose of this study was to investigate the prevalence and related factors of incisor trauma among 1200 second grade students in Taichung City, Taiwan. METHODS The study population consisted of 1200 second grade students, 645 boys (53.8%) and 555 girls (46.3%), at four elementary schools in Taichung City, Taiwan. This survey was composed(More)
Taiwan was a hyperendemic area for hepatitis A virus (HAV) infection before the late 1980s. The seroprevalence of HAV infection was higher than 90% with most HAV infection occurring during childhood. This study was to estimate the seroprevalence of HAV infection among preschool children in central Taiwan. A community-based survey was carried out in 54(More)
In an attempt to modify the physical properties of microcrystalline cellulose (MCC), the slurry form of this material was codried with beta-cyclodextrin (beta-CD). MCC slurry was blended with beta-CD at concentrations of 10%-50% w/w as a dried mass relative to MCC. The mixtures were then granulated with water and codried at 60 degrees C for 12 h or until a(More)
Vertical root fractures (VRFs) in teeth without endodontic treatment are uncommon. A clinical study was done on 64 cases of VRFs in 61 Chinese patients to define better the clinical characteristics, diagnostic signs, and possible causes. Results showed that fractures occurred most often in first molars of patients between 40 and 69 yr of age, and the(More)
Lactose and dibasic calcium phosphate (DCP) were granulated with various concentrations of film-forming polymers by a stepwise spraying method to prepare a directly compressible matrix excipient. The film-forming polymeric latex of Eudragit RS-30D, Eudragit RL-30D, and Surelease (ethylcellulose) were used in this study as the source of the granulating(More)
Malignant lymphoma is one of the most common hematological diseases of children. The prognosis is fairly good with multimodal cancer therapy. We reported a boy with Burkitt's lymphoma in the nasal cavity who received chemotherapy and irradiation of the head and neck area at four years of age. During seven years of follow-up, we studied the developmental(More)
Solitary metastatic pituitary stalk tumors account for approximately less than 1% of all pituitary gland tumors and present difficulties in clinical diagnosis because most of them are clinically silent and usually too small to cause radiological changes. With the advance of microsurgical techniques, keyhole surgery is indicated to obtain a specimen for(More)
