Abstract
Background and Aims: Survival of periodontal ligament (PDL) cells after avulsion is an important factor in treatment prognosis. Grapefruit Seed Extract (GSE) can be a proper environment for preserving periodontal ligament cells. The objective of this study was to analyze the effect of different concentrations of GSE on the proliferation of fibroblast PDL cells.
Materials and Methods: In this study, the undifferentiated PDL fibroblasts were obtained from two human premolars teeth and cultured in Dulbecco’s modified Eagle’s medium (DMEM). The cultured cells were exposed to different concentrations of GSE. The positive and negative control groups were cultured in fetal bovine serum (FBS) 10% and in a medium without FBS 10%, respectively. The plates were incubated for 1, 6, 12, 24, and 48 hrs. The PDL cell viability was assessed by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Statistical analysis of data was accomplished using repeated measure ANOVA with Post HOC Tukey, P<0.05 was considered statistically significant.
Results: We found out that among different concentrations of GSE, 1:128 had the most impact on undifferentiated PDL fibroblasts. Although, the cell vitality was higher in the twelfth hour, 1:128 GSE and in the forty-eighth hour, 1:1024 GSE than the positive control group but they were not statistically significant (P>0.05). Furthermore, all the samples were similar to the positive control group in three of the five timeperiods (P>0.05).
Conclusion: GSE was more effective in fewer concentration and longer periods and it had no toxic effect on PDL cells. Therefore, GSE can be considred as a promoting medium in PDL regeneration of avulsed permanent teeth in the future.

Abstract
Background and Aims: Studies have shown that dental anxiety may be caused by various factors such as child mood, age, maternal emotional maturity, previous dental anxiety and parenting styles. Therefore, the aim of this study was to investigate the possible relationship between the parenting styles and pediatric dental anxiety and the predictability of this variable through parenting styles.
Materials and Methods: The present study was a cross-sectional correlational study. The study population was children aged 7 to 12 years who had referred to the dental clinics of Tehran in 1400. Sampling from one of the clinics was done randomly. A total of 100 questionnaires of modified child dental anxiety scale and parenting style inventory were given to the children and their parents and 95 of them could have been analyzed. The questionnaires were analyzed using SPSS22 software and Pearson correlation and regression tests.
Results: The results showed that dental anxiety had a negative and significant relationship with authoritative parenting style (r=-0.286, P<0.01) and a positive and significant relationship with authoritarian parenting style (r=0.342, P<0.01). Authoritarian parenting style can be a predictor of dental anxiety.
Conclusion: Knowing the predictors of dental anxiety can help a pediatric dentist analysing who is most prone to dental anxiety. Based on this approach, a relationship based on trust can be established between the dentist and parents to make the necessary recommendations to parents in the office, reduce dental anxiety and improve oral health conditions in children.

Abstract
Background and Aims: Promoting children's oral health is the basis for increasing the level of community health and the goal of pediatric dentistry. By recognizing all the factors affecting the health and formation of the child's health habits, a fundamental step can be taken to promote oral health. The aim of this study was to evaluate the effect of parenting styles and demographic characteristic on OHI-S (Simplified Oral Health Index) in 2018.
Materials and Methods: In this cross-sectional study, 244 children aged 6-12 years in Behbahan-Iran with their parents were studied. The demographic questionnaire (variables such as parents 'age, economic status, gender, occupation and parents' education were recorded) and Bumrind questionnaire were used. The oral health status of children was assessed to determine the simplified oral hygiene index. Then, the obtained data were analyzed using SPSS 25 software and regression and Pearson correlation test.
Results: The results showed that the children of parents who used the permissive method had higher score of simplified oral hygiene index (P<0.001) and simplified calculus index (P<0.001). However, in children of parents who used the authoritative parenting style, a decreased simplified oral hygiene index (P<0.001) and simplified debris Index (P<0.001) were observed. However, the method of authoritarian parenting style did not have a significant relationship with the simplified oral hygiene index (P=0.890), simplified calculus index (P=0.404), and simplified debris Index (P=0.721). |
Conclusion: Powerful authoritarin and authoritative parenting practices have a clear impact on the oral health status of children. Therefore, parenting paratices can be considered as one of the main factors affecting the oral health of children.

Abstract
Background and Aims: Dental caries affects the quality of life of children and parents, oral health and overall health which can interfere with the childrens’ daily activities and growth. The purpose of this study was to investigate the relationship between the severity of dental caries and quality of life in pre-school children.
Materials and Methods: This cross-sectional descriptive study was conducted on 145 parents and preschool children aged 2-5 years old referring to Ahvaz dental school and a pediatric dentistry office in Ahvaz city. The convenient sampling method was used and participants were patients referred to the faculty of dentistry and one pediatric dentistry office in Ahvaz. Early Childhood Oral Health Impact Scale (ECOHIS) questionnaire was used to evaluate the oral health related quality of life. The demographic information and dmft index (decayed, missing, and filled teeth) was assessed for children. Statistical analyzes included descriptive statistics, Spearman and Pearson tests.
Results: The mean age of children was 4.12 ± 1.2 years. 72 children (49.65%) were boys and 73 of children (50.34%) were girls. Based on our results the mean ECOHIS score was 39.69 ± 18.95. There was a significant correlation between decreased quality of life and the lower age of the children (P=0.047), less parental education (P=0.018), more dmft score (P=0.000).
Conclusion: It can be concluded that severity of dental caries is effective on children's quality of life. The quality of life of children decreases with the increase in the dmft, lower socio-economic status of parents, and higher age of parents.

Abstract
Background and Aims: There is a traditional belief that the primary teeth can be replaced by permanent teeth and preserving them is not important. The aim of this study was to evaluate the knowledge and attitude of parents of preschool and elementary school children referring to the Specialty Clinic of Isfahan University of Medical Sciences and Imam Hossein pediatric hospital about the importance of preserving deciduous teeth and related factors.
Materials and Methods: This descriptive cross-sectional study was performed on 323 parents of preschool and elementary school children referred to the special clinic of Isfahan University of Medical Sciences and Imam Hossein Pediatric hospital. The data collection method was a questionnaire and face-to-face interview. The questionnaire was made, it consisted of 21 multiple-choice questions and descriptive questions. Data were analyzed using descriptive statistics tests and analytical tests such as t-test and Pearson correlation coefficient.
Results: The mean score of knowledge of parents was 37.5 with a standard deviation of 16.9, the mean score of attitude was 55.8 with a standard deviation of 11.1 and the mean score of performance was 41.8 with a standard deviation of 15.6 out of 100. Pearson correlation coefficient showed that there was a direct relationship between knowledge, attitude, and performance scores (P<0.001). Parents' knowledge score was directly related to the mothers' and fathers' ages (P<0.001).
Conclusion: According to the results, parents' awareness of the importance of the preservation of deciduous teeth and related factors is poor, their attitudes are neutral and their performance is poor to moderate. It is suggested to improve treatment facilities available for children in the family and to educate parents about the preservation of deciduous teeth.

Abstract
Background and Aims: Selecting the appropriate education evaluation method and the effects of this choice according to different fields of medical sciences, is one of the current priorities of medical education. Therefore, the aim of this study was to design a checklist for evaluating the practical skills of dental students and to get compared with the global ranking method.
Materials and Methods: A checklist was developed for the assessment of clinical skills of the practical pediatric course according to an action research method. 32 students were evaluated by the checklist method and 32 students were evaluated by the conventional global rating method (sampling was based on available sample). Faculty staff and students’ satisfaction regarding the two methods were reported by a 6-scaled measure and statistically analyzed by Wilcoxon Signed Ranks test. The students' scores by the two methods were subjected to paired t test for comparison.
Results: The students were more satisfied with the checklist method (P=0.003). The faculty staff considered a greater ability of the checklist method to differentiate between the students (P=0.03). However, in terms of ease of use and suitability, most faculty staff preferred the traditional method (P=0.02). In other cases, there were no significant differences in the views of students and faculty staff towards the two methods.
Conclusion: In the present study, both Checklist and global rating methods were valuable for evaluation, although due to the greater satisfaction of students and faculty staff with the developed checklist method, the possibility of identifying the weak points leading to decreased scores and better assessment of capabilities, this checklist can be used for evaluation instead.

Abstract
Background and Aims: One of the concerns of dentists is selecting a suitable brand of stainless steel crowns with maximum dimensional adaptation with primary teeth. The aim of this study was to compare the primary molar crown dimensions with that of two brands of stainless steel crowns (SSCs) in a sample of Iranian children.
Materials and Methods: In this study, 130 eligible children between 3 and 12 years (66 boys, 64 girls) were selected. After recording the demographic information, the mesiodistal, buccolingual and occluso-gingival dimensions of first (D) and second (E) primary molars were measured on dental casts and compared with the dimensions of KTR (MeiMeiMinBenjing, Benjing, China) and Shinghung (Shinhungcompany, Seoul, South Korea) SSCs. Data were assessed using chi-square test and Pearson correlation coefficient. P<0.05 was considered statistically significant.
Results: In this study, the most dimension matching of the teeth with that of SSCs were observed mesiodistally in upper D and lower D, buccolingualy in the upper D and lower D, and occluso-gingivaly in upper D and lower E. The most cases of mismatch in the mesiodistal dimensions of the teeth with that of SSCs were observed in the lower E and upper D. Also, the most cases of mismatch in the buccolingual dimension were found for upper E and lower E.
Conclusion: Both SSCs brands in this study showed significant dimensional adaptation with the primary teeth in Iranian children. The most dimensional adaptation was between KTR SSCs and maxillary primary molars, and between Shinhung SSCs and mandibular primary molars.
