To establish efficient methods for self-prevention of oral diseases, assessment of dental health behavior and knowledge in various social classes is necessary. The main purpose of this study was to determine the major differences in oral health knowledge and behavior in a group of Iranian pre-university students. In this cross-sectional study, 591(More)
—Motivated by the need for fast synchronized operation of power microgrids, we analyze the problem of single and multiple pinning in networked systems. We derive lower and upper bounds on the algebraic connectivity of the network with respect to the reference signal. These bounds are utilized to devise a suboptimal algorithm with polynomial complexity to(More)
Melanin hyperpigmentation is the result of melanin granules. "Black gums" may cause esthetic problems. Different treatment modalities have been used with the aim of removing pigmentations for esthetic reasons, all of which have some advantages and disadvantages. Recurrent lesions are the most important concept in all of these treatments. Cryotherapy is a(More)
BACKGROUND Iron deficiency is estimated to be the most common nutritional deficiency in both developed and underdeveloped nations. Iron supplements at early age may prevent iron deficiency. The aim of this study was to assess the knowledge and management of parents about using iron supplements related to dental caries and staining among Iranian children (6(More)
OBJECTIVE Educational teaching of the diagnosis of resorbed root for pulpectomy in deciduous teeth radiography has always been a big challenge in pediatric dentistry. The purpose of the study was to propose a new practical methodology to improve the quality of learning in students of dentistry. MATERIALS AND METHODS Extracted deciduous teeth were molded(More)
OBJECTIVES Caries and dental trauma are common reasons for primary anterior teeth restorations in children. This non-control clinical trial was designed to evaluate crown restorations reinforced with a sectioned file post for the restoration of severely damaged primary maxillary incisors. MATERIALS AND METHODS Thirty-eight primary maxillary incisors of 12(More)
This report presents a rare case of bi-rooted primary maxillary canines. A 6-year-old girl presented at the Department of Pediatric Dentistry, Faculty of Dentistry, Mashhad University of Medical Sciences, Iran, with the chief complaint of pain in the lower right quadrant of her dentition. Radiographic examination revealed bifurcation of primary maxillary(More)
Background and aims. Heat generated within tooth during clinical dentistry can cause thermally induced damage to hard and soft components of the tooth (enamel, dentin and pulp). Geometrical characteristics of immature teeth are different from those of mature teeth. The purpose of this experimental and theoretical study was to investigate thermal changes in(More)
—Motivated by the fact that the location(s) and structural properties of the pinning node(s) affect the algebraic connectivity of a network with respect to the reference value and thereby, its dynamic performance, this paper studies the application of intelligent single and multiple pinning of distributed cooperative secondary control of distributed(More)
BACKGROUND AND AIMS Preventing oral disease is the most desirable way of ensuring good dental health for children with heart disease. Dental and gingival infections in patients with cardiac problems may lead to infective endocarditis. The aim of this study was to evaluate oral and dental health status in children with heart disease referred to a cardiac(More)
