Volume 16, Issue 1 (7 2003)
Abstract

Statement of Problem: Anthropometry is applied in medical professions such as maxillofacial surgery,growth and development studies, plastic surgery, bioengineering and non- medical branches such as like shoe- making and eye- glasses industries.

Aim: The aim of the present study was to determine facial and cranial ratios among Isfahan young adults.
Materials and Methods: A study was done randomly on 200 boys and 200 girls, from among Isfahan young adults, with normal face patterns. Facial and cranial ratios, according to sex, were estimated and compared.
Results: The results of this study were compared with Canadian anthropometric findings by Farkas.There was no significant difference in cranial width between boys and girls but cranial length and all facial parameters (Int ,cant, go-go, zy- zy, ch-ch, Ala-Ala, low.lip, Up.Iip, Sn.gn, Sto.gn, N.sto, Ngn)were greater in boys than girls. Cranial index and , , " ,Cl ratios were greater in n - gn zy - zy zy - zy zy - zy ... slo-go sn-gn sto-gn slo-gn sto-gn . . ._girls, however, -, -, , , were greater in boys, There was no significant go-go n- gn n- gn n- sto sn - gn difference about facial index between boys and girls. Comparing facial parameters between Iranian and Canadian races, low. lip, Ala-Ala and go- go were greater among Iranians, however, Int cant ,Up. lip.

Regarding 5"~g" ratio, no n- sto sn- gn n~ gn n- gn significant difference was observed between Canadian and Isfahanian girls.
Conclusion: Considering the significant difference in the facial and cranial anthropologic ratios and sizes, among Canadian and Isfahanian young adults, the results obtained from Canadian race, should not be applied as a criteria for Iranian surgical and dental treatment plans. Due to the wide racial combinations in Iran, more studies, with wider variations, should be conducted among different Iranian races.


Development of a persian version of the children’s fear survey schedule-dental subscale (cfss-ds) among 8-12 year-old female students in Tehran

Volume 31, Issue 2 (9-2018)
Abstract
Background and Aims: Children’s Fear Survey Schedule- Dental Subscale (CFSS-DS) is considered as the most popular instrument available to assess dental fear in children. The aim of this study was to develop a Persian version of the CFSS-DS among 8-12 year-old female children resident in Tehran.
Materials and Methods: At first, the questionnaire was translated in Farsi and  back translated in English afterwards. While, the back translated version was confirmed, we considered the Persian version as the final instrument. Content validity and reliability of the questionnaire was assessed. We used test-retest method to evaluate the reliability, 287 female students aged 8 to 12 from 7 schools in 6th district of education ministry of Tehran were interviewed two times with interval of seven days. In addition, the infraclass correlation coefficient (ICC) and percentage of agreement were calculated. The score of dental fear was measured with range of 13 to 65 and changed to a number between 0 and 100. The relationship between dental fear score and the independent variables including age, history of hospitalization, last medical visit, and history of dental treatment were evaluated using the linear regression models.
Results: The mean score of dental fear was calculated 20.52. The score of dental fear was significantly associated with the last medical visit (P=0.04) and past dental history (P<0.001). The percentage of agreement was more than 80% for all the questions. In each question, Kappa was evaluated as moderate to good and ICC was good to very good (more than 0.4).
Conclusion: The findings of this study demonstrated that the Persian version of CFSS-DS was valid and reliable among 8-12 year-old children.

Volume 35, Issue 0 (5-2022)
Abstract
Background and Aims: Oral health is a necessity and part of general health and its importance in childhood is more than ever. The aim of this study was to investigate the knowledge, attitude, and practice of parents in Delfan city-Iran about oral health of their 6-12-year-old children in 2021.
Materials and Methods: The present study was a descriptive-analytical study that was performed on 365 parents of 6-12-year-old children in Delfan city. Convenience sampling was used. The questionnaires included four sections: demographic information, knowledge, attitude and practice about oral health. Data were entered in SPSS23. Independent t-test, analysis of variance and Pearson correlation were used to analyze the data. Significance level was considered 0.05.
Results: The mean age of the subjects was 36.5±7.1. 201 of parents were mothers. Parents' knowledge and attitude were good and their performance was fair. There was a statistically significant relationship between all three variables of knowledge, attitude, and practice (P<0.00). Also, there was a statistically significant relationship between the knowledge and education (P<0.00), mother job (P<0.04), father job (P<0.00), and economic status (P<0.00). There was a statistically significant relationship between the attitude with education (P<0.00), mother job (P<0.04), father job (P<0.01), and economic status (P<0.01), There was a statistically significant relationship between practice and education (P<0.00), mother job (P<0.01), father job (P<0.00), and economic status (P<0.00) of parents.
Conclusion: The results of this study showed that there was a significant relationship between the knowledge, attitude, and practice with education level, job and economic status. Therefore, oral health education for parents with low educational and economic level should be highly considered.

Abstract
Background and Aims: Idiopathic osteosclerosis is an asymptomatic local growth of cortical bone and is discovered incidentally on panoramic radiographs. The purpose of this study is to evaluate the frequency of idiopathic osteosclerosis and its radiographic features in panoramic images of patients referred to the Department of Maxillofacial Radiology, Faculty of Dentistry, Arak University of Medical Sciences (Iran) in 2022-2023.
Materials and Methods: In this cross-sectional study, 460 panoramic images from the radiology department of Arak Faculty of Dentistry were randomly selected and analyzed. The demographic information of patients, frequency of idiopathic osteosclerosis, location, and also its relationship with adjacent teeth in terms of proximity to lamina dura and periodontal ligament and radiographic features in terms of size and morphology were evaluated. The data were analyzed using the SPSS24 software.
Results: Panoramic images of 460 patients (266 men and 194 women) with an average age of 38.12 (11.75) years were evaluated. The frequency of idiopathic osteosclerosis was 6.1% (28 images). 92.9% of the lesions were in the lower jaw and 46.4% of them were near the premolar teeth. In 39.3% of the cases, the lesion was adjacent to the periodontal ligament and laminadora of the tooth. In 3.6% of the cases, it was associated with a small displacement of the adjacent tooth, and 17.9% was associated with tooth root resorption. According to the results, there was no correlation between the incidence of this lesion with age and gender (P>0.05).
Conclusion: According to the findings of this study, the frequency of idiopathic osteosclerosis in the patients referred to Arak dental school was reported as 6.1%. Most of these lesions were observed in the back of the lower jaw and thus, it is important to be able to distinguish this lesion from the radiopaque lesions of the jaw which need treatment.
