Treatment Outcomes of Pulpectomy in Primary Maxillary Incisors Filled with ZOE and Metapex: A Two-year Retrospective Study.

Objectives: To address a literature gap by evaluating, in a larger set of samples, the clinical and radiographic outcomes of pulpectomy in primary maxillary incisors using ZOE and calcium hydroxide/iodoform paste. To also identify the predisposing factors for treatment outcomes.

Study Design: Medical charts of 124 patients (aged 16 to 60 months) and radiographs of their incisors (309 incisors) were reviewed (128 with ZOE and 181 with Metapex).

Clinical Orodental Anomalies in Taiwanese Children under Age Six: a Study Based on the 1995-1997 National Dental Survey.

There are few published studies that report the prevalence of intraoral anomalies for young children. The purpose of this study was to investigate the prevalence and distribution of several congenital oral and paraoral anomalies in Taiwanese children under age six. Twenty-five cities and townships were randomly sampled in different areas of Taiwan using the stratified method.

Torus Palatinus in Taiwan Patients Receiving Peritoneal Dialysis and Hemodialysis: A Prospective Observational Study.

Purpose: A consensus about the pathogenesis of torus palatinus (TP) in patients receiving dialysis still eludes the scientific community. This prospective observational study investigated the epidemiology of TP in peritoneal dialysis and hemodialysis patients and analyzed the influences of multiple pathogenic factors such as mineral and bone disorders, genetic, environmental or nutritional triggers, progression of age, heredity, climatologic or biomechanical causes, and hyperparathyroidism on the formation of TP.

Methods: Between 2013 and 2016, a total of 575 chronic dialysis patients (441 on hemodialysis and 134 on peritoneal dialysis) were recruited from Chang Gung Memorial Hospital, Taiwan.

Survey of Torus Palatinus in Patients with End-Stage Renal Disease Undergoing Hemodialysis.

Introduction: This study attempted to survey the oral findings of hemodialysis patients and analyze the prevalence and predictors for torus palatinus TP) in this patient population.

Methods: A total of 322 hemodialysis patients were recruited. Patients were organized into two groups, based on the presence (n=93) or absence (n=229) of TP.

Enhancement of Osteoblastic-Like Cell Activity by Glow Discharge Plasma Surface Modified Hydroxyapatite/β-Tricalcium Phosphate Bone Substitute.

Glow discharge plasma (GDP) treatments of biomaterials, such as hydroxyapatite/β-tricalcium phosphate (HA/β-TCP) composites, produce surfaces with fewer contaminants and may facilitate cell attachment and enhance bone regeneration. Thus, in this study we used argon glow discharge plasma (Ar-GDP) treatments to modify HA/β-TCP particle surfaces and investigated the physical and chemical properties of the resulting particles (HA/β-TCP + Ar-GDP). The HA/β-TCP particles were treated with GDP for 15 min in argon gas at room temperature under the following conditions: power: 80 W; frequency: 13.

The preliminary results of the differences in craniofacial and airway morphology between preterm and full-term children with obstructive sleep apnea.

Background/purpose: The prematurely born and obstructive sleep apnea (OSA) could affect craniofacial and airway growth. The purpose of this study is to compare the differences in craniofacial and airway morphology between preterm and full-term children both with OSA problem.

Materials And Methods: The differences in craniofacial and airway morphology between preterm children and full-term children both with OSA problem during the prepubertal (age 6-10) and pubertal (age 11-14) period were measured using lateral cephalometric radiograph.

Isolation of Mesenchymal Stem Cells from Human Deciduous Teeth Pulp.

This study aimed to identify predictors of success rate of mesenchymal stem cell (MSC) isolation from human deciduous teeth pulp. A total of 161 deciduous teeth were extracted at the dental clinic of Chang Gung Memorial Hospital. The MSCs were isolated from dental pulps using a standard protocol.

A 2-year retrospective study of pediatric dental emergency visits at a hospital emergency center in Taiwan.

Background: There is a paucity of information regarding pediatric dental emergencies in Taiwan. This study investigates the prevalence and characteristics of the pediatric dental emergency services provided at a medical center.

Methods: This study included a retrospective chart review of patients under 18 years of age with dental complaints who visited the Emergency Department (ED) of Linkou Medical Center of Chang Gung Memorial Hospital from January 2012 to December 2013.

A retrospective study of sodium hypochlorite pulpotomies in primary molars.

Background/purpose: Formocresol has been a popular pulpotomy medicament for primary molars, however, its toxicity and potential carcinogenicity leaves room for other alternatives such as sodium hypochlorite (NaOCl). The purpose of this study is to evaluate the clinical and radiographic success rate of 5% NaOCl pulpotomy in primary molars.

Materials And Methods: A retrospective research of patient records from January 1, 2009 and December 31, 2012 was conducted to evaluate the clinical and radiographic success rate of 5% NaOCl pulpotomy in primary molars.

Oral Tori in Chronic Peritoneal Dialysis Patients.

Background: The pathogenesis of oral tori has long been debated and is thought to be the product of both genetic and environmental factors, including occlusal forces. Another proposed mechanism for oral tori is the combination of biomechanical forces, particularly in the oral cavity, combined with cortical bone loss and trabecular expansion, as one might see in the early stages of primary hyperparathyroidism. This study investigated the epidemiology of torus palatinus (TP) and torus mandibularis (TM) in peritoneal dialysis patients, and analyzed the influences of hyperparathyroidism on the formation of oral tori.

Oral tori in chronic hemodialysis patients.

Background: This study investigated the epidemiology of torus palatinus (TP) and torus mandibularis (TM) in hemodialysis patients and analyzed the influences of hyperparathyroidism on the formation of oral tori.

Method: During 2013, 119 hemodialysis patients were recruited for dental examinations for this study.

Results: The prevalence of oral tori in our sample group was high at 33.

Salivary microbial counts and buffer capacity in children with acute lymphoblastic leukemia.

Purpose: The aim of this study was to evaluate the caries activity in children undergoing maintenance stage chemotherapy courses.

Methods: Forty-six children with acute lymphoblastic leukemia (ALL) were examined, the age ranged from 3 to 12 years with a mean age of 7(1/2) years. They were under maintenance stage chemotherapy at the Department of Pediatric Hematology of Chang-Gung Memorial Hospital, Taoyuan, Taiwan.

Management of talon cusp affecting the primary central incisor: a case report.

Talon cusps are relatively rare dental anomalies that manifest as accessory cusplike structures and project from the cingulum area of the anterior teeth. The condition can occur in both the primary and permanent dentitions. However, the occurrences of anomalous cusps are rather infrequent in the primary dentition.
