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.
 

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.

Background and Aims: Dental caries is a multifactorial chronic disease that affects the majority of the population, causing a very serious health problem worldwide This population-based cross-sectional study was conducted with the aim of evaluating the incidence of dental caries, parents' understanding of children's oral health, and factors affecting the use of dental services in the population of primary school children.
Materials and Methods: This descriptive-analytical cross-sectional study was conducted and the desired information was collected using the OHL-AQ questionnaire, the validity and reliability of which was confirmed in the previuos study. A total of 400 students between the ages of 6 and 12 were included in the study. The decay, missing, filling (DMFT) Index was used for calculating dental caries index. The statistical population of this research were the parents and students of the primary level of education in the six districts of Isfahan city in the academic year of 1402-1403. The sampling method was random cluster sampling. Then, the data collected from the examinations and questionnaires were analyzed by correlation tests, Independent Samples
T-Test and linear regression using SPSS software version 26, and the error level was 0.05.
Results: Among 400 students, the highest frequency (20.8%) was related to the second grade and the lowest frequency (12.5%) was related to the sixth grade of education. The average age of students' parents was 39.8 years. In most cases (56%) parents had university education. The educational level of students and the level of parents’ education had a significant relationship with the DMFT score (P<0.001). The average oral health information literacy score and average age of the parents had a significant relationship with the DMFT score (P<0.001). In this study, the average oral health information literacy score of parents was estimated to be 9.1.
Conclusion: In the present study, the information literacy score of the parents was evaluated as average and showed a significant relationship with the DMFT index. Also, the educational level of the student and the level of parents’ education had a significant relationship with the DMFT score. Therefore, it can be concluded that promotion of the level of education in the society is necessary as it can affect the level of oral health of children.
