[Evaluation of realization rate of under curriculum at Tehran's universities school of dentistry from 2001-2005]

Considering the number of dental graduates and the increasing trend of their concerns and goals of the educational program, a lack of information about This, and its related problems, the aim of this study was to evaluate student opinions on academic curriculum the following dental schools: Tehran University of Shahid Beheshti Islamic Azad university and Shahed University, from 2001 to 2005.This cross-sectional study was conducted on all graduated students. All students were asked to fill out questionarre, stating their opinion of their academic curriculum, the questionarre included topics and 10 variables which wear classified into 5 categories of completely, Moderately, slightly and insufficiently adequate. Related variables, including school of dentistry and personal attributes were also taken into consideration and chi-2 statestical test was utilized for date analysis. Out of 1481 cases of dental graduated, study was conducted on 662 person Results of realization was 12.3%, 27.4%, 33. 6%, 14.9%, 11. 8% for complete, high medium low very low respectively and there are 60.3% of non realization and in this study. the most non realization was about Basic Sciences [71.8%] and insufficiency of requirement [71.6%] rate of realization was different in the universities and female and single graduated [that living with her family had more non realization] It seems non realization of curriculum and its related problems are worrisome and necessary performance for reduction of these problemsis recommended

[Evaluation of patients' satisfaction of departments in Islamic Azad University Dental branch, in 2009]

Patient satisfaction is one of the most important factors to improve the quality of educational centers thus increasing patient referral and promote practical training of the students. To now in this faculty no such study has been done, so this research aimed to evaluate patients' satisfaction from dental care given in different departments of Tehran faculty of dentistry, Islamic Azad University year1387. In this cross sectional study 1500 subjects who referred consequently were selected from clinics with the same proportional ratio of patient referral to every clinic. After explanation of project to every subject through interview, satisfaction was estimated by 13 questions about distant way, waiting time, treatment duration with a range of 3 options of completely satisfied, relatively satisfied, dissatisfied and ranking of 0, 1, 2. Total rank less than 1/3 was known as dissatisfied, between 1/3-2/3 as relatively satisfied, and higher than 2/3 as satisfied. The role of related factors was subjected to chi-square statistics. 71% of all subjects spoke out satisfaction, 27.5% were relatively satisfied, and 1.5% dissatisfied. The prevalence of dissatisfaction in the population was estimated from 26.7% to 31.3%. The most dissatisfaction was related to removable denture patients:64.7% and the least was in oral surgery clinic :13.5% [p<0.05]. The most dissatisfaction factor was long distance and waiting room ambiance but the least dissatisfaction was about student behavior, hygiene and professors behavior. The satisfaction level of patients in Tehran dental faculty of Islamic Azad University was acceptable but according to presence of dissatisfaction in patients and its consequences, appropriate improvements are recommended

[Comparing the spectrophotometric and potentiometric methods in determining the concentration of fluoride in water]

According to the importance of fluoride in water based on "DMFT" and 2 other reports which indicates that Spectrophotometeric method for measurement the fluoride water can not show the real amount of flouride, Potentiometer seems to be better than Spectrophotometer. To compare these two methods for measuring the amount of flouride, this research carried out in organic chemistry laboratory of Tehran University between 2006 and 2007. In this descriptive study, after obtaining the distilled water, they were prepared in 7 groups with 0, 0.35, 0.67, 0.7, 1, 1.2, 1.5 ppm of fluoride in 14 polyethylene containers and 2 samples were prepared from each type. In following, half of them were measuerd by standard spectrophotometer method [with the use of visible instrument in the same wave length, amount of light coefficient with standard solutions]. Using standard solutions of 10[-1] M up to 10[-5] M fluoride in the other half of samples, the calibration curve according to the findings was drawn. By studying the potentiometer amounts of samples and compare them with calibration curve, sample density were found. At the end, findings were changed to ppm. Therefore, the amount of fluoride in water were determined and the difference to the real fluoride in samples in each method were indicated. This difference in each method was calculated by paired-t test, whereas Mann-Whitney U test evaluated two groups with each other. The research studied 14 water samples with real fluoride of 0.77 +/- 0/58. In spectrophotometer method the fluoride amount was 0.99 +/- 0/58 with the difference of 0/82 +/- 0.23 from real amount [P<0.5]. In potentiometer this amount was 0.77 +/- 0/52 with the difference of 0.02 +/- 0.01. [P<0.4]. Amount of fluoride in spectrophotometer is 19.5% higher than potentiometer. Potentiometer method is better than spectrophotometer for indicating the fluoride in water and this method is, therefore, recommended
