ABSTRACT
Human resources development is a concept which is related to training and developing the employees in organizations. At the present time, caring management approach [process reengineering, total quality management, learning organization management resource development] have an important role in human resource development. This study explores the determination of effective approach in human resources development, of nursing managers. In this exploration study, a list of effective factors in human resources development was prepared. After wards, by using the expects, opinions, several polls were taken and at last seven factors were chosen. In the next step, the priority of factors was determined by the pair comparison method and four criteria and their weights were chosen by EC pro software. Consequently, the four approaches which were identified in the previous section were studied with analysis heiress presses. In this study, the factors affecting human resource development of nursing managers include: setting a common goal developing systematic insight, communication freedom and sharing [exchanging] information operation, taking suggestions, increasing work insight and access to the operation of and educational backgrounds of employees. Based on the experts' opinions, learning organization is the best application ever known in human resource development in nursing. The findings of this study suggest that the reinforcement of learning organization's insight in nursing management is an effective way in human resource development. So by using this approach and by considering the priority of effective factors, it can be suggested to nursing managers and similar managements as on operational model
ABSTRACT
Statement of Problem: One of the complications in reconstruction of the primary teeth with stainless steel crowns [SSC] is microleakage at the crowns' margins. Luting cement that can seal the margins can reduce the microleakage
Purpose: This research was performed to compare the ability of four adhesive cements for reducing microleakage at the SSC margins
Methods and Material: In this experimental study, standard preparation was performed on 60 primary molar teeth for SSC restorations. After adjusting SSC, the samples were randomly divided into 5 groups, each containing 12 teeth. Then, the SSCs were cemented in each group with different cements. These groups contained Zincphosphate [Elite, ZP], Polycarboxylate [Durelon, PC], Glass ionomer [Ketac cem, GI], Resin-modified glass ionomer [Rely X luting 2,RMGI], and Resin-modified glass ionomer with bonding agent [[Single Bond,SB]. After thermocycling and using dye penetration [methylen blue 1%], the samples were evaluated under a digital microscope. For comparison of the microleakages among the groups, t-test, ANOVA and LSD tests were used
Result: Microleakage in the adhesive cement groups [GIC, RMGIC, RMGIC+BA] was significantly lower than that in the non-adhesive [ZP, PC] groups [p <0.05]. Comparison of the cements revealed a statistically significant difference among all the groups [p <0.001]. RMGI+SB had the lowest microleakage followed by RMGI, GI, ZP. PC cement showed the greatest microleakage
Conclusion: Adhesive cements were more effective in reducing the microleakage in cementation of SSC than non-adhesive cements. The use of bonding agents with RMGI cement showed more acceptable results in comparison with RMGI cement
ABSTRACT
In this case report, dental status of a boy aged eight years, referred to the pediatric department of dental school of Shiraz University of Medical Sciences is presented and explained. His main chief complaint was reduced number of the teeth. During clinical evaluation, hypodontia, and in radiographic examination, congenital missing and rootlessness of many permanent teeth were evident. The patient did not have any evidence of systemic diseases, developmental anomalies and/or syndromic defects

Formocresol has been considered as a popular pulpotomy medicament in the primary dentition for the past 60 years. However, concerns have been raised on its potential toxicity and mutagenicity during recent years. Therefore, many alternatives have been recommended over the years for formocresol as pulpotomy agents in primary teeth. The aim of this study was to evaluate the clinical and radiographic success rates of electrosurgery as a pulpotomy technique in pulpotomized primary molar teeth. Forty primary molar teeth were randomly selected and treated using needle shape electrode in an electrosurgical unit as the pulpotomy technique. All teeth were treated in one treatment session. Patients were placed on a recall program and were evaluated clinically and radiographically after 6-12 month follow up period. Any evidences of pain, fistula, swelling, abnormal mobility, furcation radiolucency or pathologic root resorption were considered as criteria for failure of treatment. After 6-12 month observation period, the clinical success rate was found to be 100% while the radiographic success rate was 84.2%. The overall success rate for this type of treatment showed to be 84.2%. Since electrosurgery is a nonpharmacologic, easy to use, rapid and effective technique, it may be recommended as a suitable alternative for formocresol pulpotomy in primary molar teeth
ABSTRACT
Formocresol had been a popular pulpotomy medicament in the primary dentition for the past 60 years. However, concerns had been raised about its potential toxicity and mutagenicity during recent years. So, many alternatives were recommended over the years for formocresol as pulpotomy agents in primary teeth. The aim of this study was to evaluate the clinical and radiographic success rates of ferric sulfate as a pulpotomy agent in pulpotomized primary molars. 40 primary molar teeth were randomly selected and treated using ferric sulfate [15.5% solution] as the pulpotomy agent. All were treated in one treatment session. Patients were placed on a recall program and were examined clinically and radiographically after 6-12 months follow up period. Any evidences of pain, fistula, swelling, abnormal mobility, furcation radiolucency or pathologic root resorption were considered as criteria for failure of treatment. After 6-12 months observation period, the clinical success rate was 94.8% and the radiographic success rate was 76.9%. The overall success rate for this type of treatment was 76.9%. Since ferric sulfate is a non toxic and easy to manipulate material, after some modifications in treatment technique, it may be recommended as a suitable alternative for formocresol
ABSTRACT
Statement of Problem: Otitis Media [OM] is one of the most common diseases in young children which is regarded as a debilitating and costly important disease
Purpose: The purpose of this study was to assess some of the possible risk factors that might be related to the occurrence of OM in the first two years of life
Materials and Methods: The study was carried out on 200 children, with the age of 2 years or younger. Parents were asked to complete a questionnaire on the occurrence of OM, Pacifier use, thumb sucking, blanket sucking, feeding habits and also about parental smoking, parental educational level and occurrence and duration of day care attendance. Pearson Chi Square test was used for statistical analysis
Results: More than 75% of children were reported to have experienced one or more episodes of OM during their first two years of life. It was found that pacifier use, feeding habits, blanket sucking, day care attendance, parental smoking and parental educational level were significantly associated with the occurrence of OM
Conclusion: OM was a common disease during the first two years of life and significant association existed between OM and different sucking habits, day care attendance, parental smoking and parental education. In this regard, parents' information and attention on the possible risk factors can significantly reduce the risk of OM occurrence
