In addition direct smear was also applied for the watery and loose samples. Finally, collected scotch tape samples were examined microscopically. Descriptive statistics indices including means , standard deviations, and frequencieswere used for reporting the results .
Results: The overall prevalence of intestinal parasitic infections among the children of Shahroud's kindergartens was 22.2%. Also, the prevalence of the infections among males and females were 24.1% and 20.4%, respectively. The highest prevalence of infections were belongs to Giardia lamblia and Endolimax nana (7.4 and 4.8%), respectively. Also, Trichomonashominis had the lowest prevalence (0.5%). Prevalence of infection caused by Enterobiusvermicularis was (2.1%), the average agesof children infected by Enterobiusvermicularis and Giardia were 5.1 and 4.7, respectively. There was no difference in order of parasites infection on the basis of gender.
Conclusion: The prevalence of infection caused by Enterobiusvermicularis among the children was considerably low. Also, the prevalence of Giardia lamblia was lower than the average of its prevalence in countrywide scale. Although the health services have been effectively enhanced, the prevalence of intestinal parasites, Giardia lamblia in particular, is still problematic.

The aim of this study was to determine the frequency of ectopic eruption of the first permanent molar and canine in patients referred to Ardabil dental school.
Methods: By observing the panoramic radiographs, recorded from 2016 to 2017, the frequency of ectopic eruption of first permanent molars in children aged 5 to 8 years and permanent canine in children aged 10 to 13 years was determined. The frequency distribution based on sex, involved jaw, unilaterality and bilaterality were evaluated using Chi-Square test.
Results: the frequency of ectopic eruption of the first permanent molar and permanent canine was 2.1% and 6.4% respectively. There was no significant difference in the frequency of ectopic eruption of the first molar, based on the patient's gender (p=0.366), jaw (p=0.132), and unilateral or bilateral involvement (p=0.366).Also, there was no significant difference between the frequency of ectopic eruption of permanent canine and the patient's gender (p=0.384), unilateral or bilateral involvement (p=0.056). The ectopic eruption of the permanent canine in the maxilla was greater than the mandible (p=0.012).
Conclusions: In this study, the frequency values of ectopic eruption were 2.1% and 6.4% for the first permanent molar and permanent canine respectively that were in the range of other studies reported from other populations.

Abstract
Background: Elective abortion is one of the factors affecting the decline in population growth and fertility rates and is a complex issue in the field of reproductive health. Given that elective abortion is prohibited in Iran, there are no accurate statistics on it. This study aimed to investigate the frequency, causes and methods of elective abortion and demographic characteristics of related women referring to Alavi Educational and Medical Center in Ardabil city from 2022 to 2023.
Methods: This descriptive, cross-sectional study was conducted on women referred to Alavi Hospital in Ardabil for elective abortion from November 2022 to March 2023. Data were collected through referrals to women's records, interviews, and questionnaires. Data analysis was carried out using SPSS-16 and descriptive statistics.
Results: 116 women were referred to Alavi Hospital in Ardabil for elective abortion. The largest number of women (50.9%) was in the age group of 25-34 years and most of them (79.3%) lived in urban areas. The gestational age of 78.4% of them was less than 12 weeks. In terms of education, 41.4% of women had an intermediate level of education. 62.9% of women used natural contraception and 87.1% used the misoprostol method for abortion. Desire to Limit childbearing (20.7%) was the main reason for abortion. 54.3% of women had no history of previous abortion.
