Background and Aim: Diagnosis of occlusal caries in early stages is more difficult than other types, and needs practical proficiency and accuracy as well as application of advanced and modern equipments. The aim of this study was to evaluate the variations among dentists in diagnosis of occlusal caries. Materials and Methods: In this descriptive cross-sectional study, 6 permanent first molar ...
In this paper we present Maximal Size Matching with Permanent Selection (MSMPS) algorithm [1] which is responsibilities for circuit switching control. We discussed the general algorithm rules and circuit switching architecture which was used in our research. This switch architecture uses Virtual Output Queues (VOQ) for buffering incoming packets. MSMPS algorithm based on permanent connections b...
For permanent and partially permanent, uniformly bounded Lotka-Volterra systems, we apply the Split Lyapunov function technique developed for competitive Lotka-Volterra systems to find new conditions that an interior or boundary fixed point of a Lotka-Volterra system with general species-species interactions is globally asymptotically stable. Unlike previous applications of the Split Lyapunov t...
Statement of Problem: Previous experiences and clinical observations indicate that enamel hypoplasia and hypocalcification of first permanent molars, among infants born in Cessarian Section Delivery (C/S) is more common than those born in Normal Vaginal Delivery (NVD). Moreover, the first permanent molar is the only tooth that its "cusp tip calcification" starts exactly at the time of delivery....
objective: morphological changes of ca1 neurons in rat hippocampus after transient and permanent focal cerebral ischemia were studied to clarify the nature of postischemic cell death in the subfield. materials and methods: male adult rats were divided into 3 groups: control (shamoperated), transient ischemic group (30 minutes of mcao followed by 48 hours of reperfusion), and permanent ischemic ...
A retrospective analysis of the National Practitioner Data Bank (NPDB) Public Use Data File was performed on anesthesia-related malpractice payments from 2004 to 2010. Anesthesia-related allegations, malpractice act or omission codes, severity of injury, and cost were assessed. The NPDB captured 369 anesthesia-related malpractice payments associated with Certified Registered Nurse Anesthetists ...
Background and Aim: Nanoleakage can cause discoloration around restoration margins, secondary caries, postoperative sensitivity and finally loss of restoration, thus adequate hybrid layer is of primary importance in prevention of nanoleakage in adhesive restorations. Because of structural differences between primary and permanent dentin, evaluation of nanoleakge in primary teeth is very importa...
Abstract Introduction: This study aimed to determine the prevalence of dental caries and plaque in patients undergoing removable orthodontic treatment. Materials and Methods: In this cross-sectional study, 57 patients were selected and examined for dental caries (clinically and radiographically) and plaque (O’Leary Index) on permanent and primary teeth. Data were analyzed using chi-square an...
Objectives: One of the education ministry’s concerns in high schools is the problem of academic achievement. The researches have mentioned that student’s false attribution and absence of scholastic counseling service are the most important factors affecting student’s low performance and achievements. The main goal of this research was to study the rate of cognitive reconstructive effect on attr...
