Evaluation of Reasons of Permanent Teeth Extraction in Iranian People (2009)
Kakoei S.,Fatemian M.,Eskandari Zadeh A.,Parirokh M.
Journal of Dentistry , 2012,
Abstract: Statement of Problem: Everyday, many people lose their teeth because of various reasons. Knowing the reasons of tooth extraction would help officials to make decisions for helping patients saving their teeth.Purpose: The aim of this study was to investigate the reasons of teeth extraction in dental clinics and some private offices in the city of Kerman in November 2009- February 2010.Materials and Method: In this cross-sectional study, the reasons of teeth extraction in 2076 teeth from 1500 patients selected by simple sampling from Kerman dental clinics were evaluated. Personal data such as gender, age, educational level, occupation, and family size as well as the main reason of tooth extraction (decay, periodontal diseases, prosthesis, tooth impaction, orthodontic reasons, and patient’s request) and the type of tooth were collected by a checklist. Data were analyzed in SPSS, version 11.5 using χ2 test.Results: The two main reasons of tooth extraction were dental caries (43.6%) and patient request (30.6%), respectively. Overall, the first and third molars of the lower jaw were the most commonly extracted teeth. There was a significant relationship between gender and tooth extraction because of caries and orthodontic reasons ( p <0.0001). Meanwhile, the patients’ age had a significant relationship with most teeth extraction reasons ( p <0.0001). Except for patient’s request, educational level had a significant impact on other teeth extraction reasons ( p <0.0001). Conclusion: According to the results of this study, the most common reasons of tooth extraction were dental caries and patient request despite their restorability. Preventive programs and routine dental examination are recommended.

A - Mogharehabed,S Amin Eskandari
Journal of Isfahan Dental School , 2005,
Abstract: Introduction. The periodontal inflammation is one of the most common oral and dental diseases. Periodontitis is advanced periodontal bacterial infection. At present treatment of this disease is oral hygiene instructions, scaling and root planning, plaque control with different mouth washes and in some cases, periodontal surgery. In this investigation, Benzydamin was used as mouth wash which has anti pain and anesthetic properties. The purpose of this research was to study anti-inflammatory effects of using Benzydamin mouth wash 0.15 percent on moderate periodontitis.Material and Methods. This was a clinical test study, which has been done in Isfahan University (School of Dentistry). Sample included 80 patients, (52 female and 28 male) with an average age of 27 years. Patients who had moderate periodontitis were tested and divided into 40 person group (case and control). In both groups before performing the firt phase of treatment, index of gingival inflammation and bleeding index was determined. In case group, patients were given both oral hygience instructions and oral Bensydamin month wash. In control group only oral hygiene instructions were given to them. After one week, both case and control groups were recalled and once more indexes determined and then average was made. Acording to statistical formulas descriptive statistic and t-tests, curves and tables were made.Results. The mean for bleeding index before clinical test were 2.01 and 1.7 and after clinical test were 1.22 and 1.27 for both case and control groups. These differences between two groups were significant. But the mean for gingival inflamation index before and after clinical test were 2.18, 2.01 and 1.87, 2.03 which in both stages. Their differences were not significant.Discussion. Rsults indicate Benayamin month wash will decrease gingival bleeding and to lesser extend gingival inflamation. In control group, bleeding index was decreased slightly which can be due to oral hygiene instructions.Key words. Moderate periodontitis, Benzydamin hydrochloride 0.15%.
Simpson’s Method for Solution of Nonlinear Equation  [PDF]
Hamideh Eskandari
Applied Mathematics (AM) , 2017, DOI: 10.4236/am.2017.87073
Abstract: The programs offered for solving nonlinear equations, usually the old method, such as alpha, chordal movement, Newton, etc. have been used. Among these methods may Newton’s method of them all be better and higher integration. In this paper, we propose the integration method for finding the roots of nonlinear equation we use. In this way, Newton’s method uses integration methods to obtain. In previous work, [1] and [2] presented numerical integration methods such as integration, trapezoidal and rectangular integration method that are used. The new method proposed here, uses Simpson’s integration. With this method, the approximation error is reduced. The calculated results show that this hypothesis is confirmed.
Reconstruction of Shape and Position for Scattering Objects by Linear Sampling Method
A.R. Eskandari,M. Naser-Moghaddasi,M. Eskandari
International Journal of Soft Computing & Engineering , 2012,
Abstract: This paper presents an approach for shape and position reconstruction of a scattering object using microwaves where the scatterer is assumed to be a homogenous dielectric medium. The employed technique assumes no prior knowledge of the scatter’s material properties like electric permittivity and conductivity, and the far-field pattern is used as the only primary information in identification. The approach proposed consists of retrieving the shape and the position of the scattering object using a linear sampling method. The technique results in high computational speed and efficiency. In addition, the technique can be generalized for any scatterer structure. Numerical results are used to validate the feasibility of the proposed approach.
A comparative Survey on the Effect of Enamel Matrix Protein in Treatment of Two Wall Intrabony Periodontal Defects (Alone or in Combination with Autogenous Bone Graft)
N.Abolfazli,A.Eskandari
Journal of Dental Medicine , 2005,
Abstract: Statement of Problem: Regenerative periodontal procedures are one mode of therapy that attempts to restore the lost supporting structures of the dentition around a previously diseased root surface.Purpose: The purpose of this study was comparison between Enamel matrix proteins (EMP) used alone or in combination with autogenous bone graft (ABG) in the treatment of human intrabony periodontal defects.Materials and Methods: This clinical trial study, was done on 8 pairs of matched two wall intrabony periodontal defects with 5 mm or more probing depth and 3 mm or more depth of intrabony componentfollowing phase I therapy. In control sites Enamel matrix proteins (EMP) and in lest sites EMP with autogenous bone graft (ABG) was used.Results: No differences were found in terms of oral hygiene and defect characteristics, at baseline. Six months after treatment, both procedures significantly improved the clinical probing depth and clinical attachment level. Although bone fill was significant for both groups but EMP+ABG significantly showed more bone fill and defect resolution (bone fill 2.75mm versus 3.67mm). Crestal resorption was the same for both groups and its difference was not significant.Conclusion: The results of this study demonstrates that both procedures improves clinical parameters and combined use of EMP with autogenous bone graft will promote more bone fill and more defect resolution. A difficulty in obtaining sufficient amounts of autogenous bone from intra oral sites is one of the limitations ofthis procedure.

Abstract: A 5.5-year-old boy is reported as a case of Cornelia De Lange syndrome. The patient had pathognomonic facies with bushy eyebrows meeting over the root of the nose, hypertelorism, antimongoloid slant of palpebral fissures, sever psychomotor retardation, hirsutism, primordial growth deficiency, marked reduction anomalies of hands with hypertension and hypoplastic gentitalia, micrognathia and normal chromosomal studies. Fetal hydantion syndrome as well as trimethadoione syndrome was ruled out. A similar case in his family was noty reported. This is the second case of Cornelia De Lange syndrome reported from Iran.
The role of fuzzy logic in modeling, identification and control
Lotfi A. Zadeh
Modeling, Identification and Control , 1994, DOI: 10.4173/mic.1994.3.9
Abstract: In the nearly four decades which have passed since the launching of the Sputnik, great progress has been achieved in our understanding of how to model, identify and control complex systems. However, to be able to design systems having high MIQ (Machine Intelligence Quotient), a profound change in the orientation of control theory may be required. More specifically, what may be needed is the employment of soft computing - rather than hard computing - in systems analysis and design. Soft computing - unlike hard computing - is tolerant of imprecision, uncertainty and partial truth.

M Eskandari Torbaghan,A.L Astaraei,M Eskandari Torbaghan,A Ganjali
Journal of Science and Technology of Agriculture and Natural Resources , 2010,
Abstract: Chlorine and sulfate toxicity in water and soils are the main factors limiting growth and yield of most plants. Tolerance and sensitive indexes related to Cl and SO4 in irrigation water and effect of nitrogen fertilizer on barley were evaluated in a completely randomized design with three replications, under greenhouse conditions. Quantity salinity tolerance and susceptibility indices such as Mean Productivity (MP), Tolerance Index (TOL), Geometric Mean Productivity (GMP), Stress Susceptibility Index (SSI), Reduction Yield Ratio (Yr) and Stress Tolerance Index (STI) on the basis of plant yield with stress (Ys) and without stress (Yp) conditions were determined. Results showed that STI had a positive and highest significant correlation with grain and straw yields, compared to other indexes. Study of Standard Beta contents in grain and straw with STI index showed that the impact of Cl had a greater effect on reduction of salinity tolerance than SO4. Also Cl/SO4 ratios of 1:3 and 1:2 for grain and 1:2 and 1:1 for plant straw brought about highest tolerance to salinity, compared to non stress conditions. The scatter plot also confirmed such findings.
Neural Correlates of Developmental Coordination Disorder: The Mirror Neuron System Hypothesis  [PDF]

Abstract: Primary impairments of developmental coordination disorder (DCD) include impairments in motor skill, motor learning, and imitation. Such difficulties present challenges for individuals with DCD and may persist into adulthood, negatively impacting daily life in school, work, and social domains. A better understanding of the neural correlates of motor and imitation impairments in DCD holds the potential for informing development of treatment approaches to address these impairments. Although the disorder is assumed to be of neurological origin, little is known of the brain-based etiology of DCD. In recent years the discovery of a fronto-parietal circuit—known as the mirror neuron system—has enabled researchers to better understand imitation, general motor functions, and aspects of social cognition. Given its involvement in imitation and other motor functions, we propose that dysfunction in the mirror neuron system may underlie the characteristic impairments of DCD. We review literature pertaining to the mirror neuron system and develop a theory of disordered mirror neuron functioning in DCD. Finally, we review the limited neuroimaging literature available on neural correlates of DCD and show that the findings from those investigations are congruent with a mirror neuron system theory of DCD. Future research in this population should be designed to investigate specifically mirror neuron regions in individuals with DCD during skilled motor tasks and imitation in particular.
