Abstract
Background & objectives: File fracture is one of the main concerns in root canal therapy, which can affect endodontic treatment outcomes. The present study aimed to assess the fracture rate of the Smart Tract X3 as a new file system, in comparison with the commonly used rotary file system, during the preparation of simulated severely curved root canals.
Methods: A total of 180 resin blocks with simulated severely curved canals were randomly assigned to three equal groups (n=60) including Smart Tract X3, ProTaper Universal and Neoniti. Each set of files was used for cleaning and shaping of five canals, in total, 12 sets of files were used to prepare 60 channels in each group. All files were prepared according to the manufacturer’s instructions. The number (%) of fractures, location, length and distance of fractured segments from the apex of the block were recorded.
Results: Overall 60 files of Smart tractX3 and ProTaper universal (5 files in a set) and 36 files of the Neoniti (3 files in a set) were used. The fracture rate did not show a statistically significant difference in between-groups comparison. All fractures occurred at the apical third of the canal with the mean length of fractured segments and the distance of fractured segments from the apex of the block 2.228±0.216 mm and 0.845±0.186 mm, respectively.
Conclusion: There was no significant statistical difference among Smart Tract X3, ProTaper Universal, and Neoniti files regarding the incidence of fracture during the preparation of five severely curved canals.

Abstract
Background: Tooth decay directly and indirectly affects the national economy of some countries. These diseases reduce the number and productivity of the workforce. Medical expenses eat up savings and investments. All these factors reduce the earning power of individuals and households and affect the national economy, so an important part of the social and economic consequences of dental caries is the impact on savings at the household level and national income or gross domestic product at the national level.
Methods: The present study was descriptive, analytical and cross-sectional. The study sample was 260 6-year-old children and 260 adults who were referred to dental centers in 1401, and were randomly selected. The patients with tooth decay received services from the health and treatment centers of Ardabil city.
Results: The total cost of dental services related to tooth decay in 6-year-old children of Ardabil city was equal to 22543323 rials for one tooth, of which 94.23% of these costs are related to direct medical costs, 2.2% to indirect medical costs and 3.57% is related to non-medical indirect costs. The total cost of dental services related to tooth decay in the adult population of Ardabil city was estimated as 3,227,897 rials for one tooth, of which 95.93% of costs are direct medical costs, 2.43% of costs are direct non-medical costs, and 1.65% of costs are indirect costs.
Conclusion: Considering the high prevalence of tooth decay in 6-year-old children and adults in Ardabil city, its treatment imposes a significant part of the costs on Ardabil households, and the limited supply of dental services in the public health sector and the lack of insurance support in paying the costs have caused that families often pay for private services out of their own pockets.

Abstract
Background: despite the many benefits of dental implants, their cost remains a controversial issue. No study in Iran evaluated the costs and benefits of this treatment accurately, so the present study aimed to investigate the economic burden of implant surgery on the urban households of Ardabil province in 2021.
Methods: in this descriptive-analytical, cross-sectional study, the economic burden of implant surgery was estimated using the cost of illness method and human capital method. In this study, based on the content and purpose, the prevalence-based approach was used and a suitable checklist was prepared. The statistical population was patients referred to public and private centers providing dental services in Ardabil city. The sample size was calculated to be 160 people and a random sampling method was used for sampling. . Data analysis was done with SPSS version 21 software and Excel software.
Results: The results of the investigation showed that the total cost of implant surgery per unit was (118680744 Rials), 82.11% of these costs were related to direct medical costs, 10.92% were related to non-medical direct costs, and 6.97% were related to indirect medical expenses. Also, the economic burden of implant surgery on Ardabil society was estimated at 71 trillion 467 billion 62 million 235 thousand 635 Rials.

Abstract
Background: Early childhood caries is a disease that affects the quality of life of a child and his overall health; it can interfere with the child's daily activities and growth process. This disease is affected by various factors such as diet, oral hygiene, social health factors and psychological issues. This study aimed to investigate the relationship between early childhood caries in children and the parents’ quality of life.
Methods: This cross-sectional descriptive study was conducted on 552 children aged 12 to 71 months in Ardabil city. The convenient sampling method was used and participants were patients who referred to Ardabil Dental Health Center. Dmft index (decayed, missing, and filled teeth) was assessed after examining the children. The World Health Organization questionnaire was used to evaluate the quality of life of the parents. The demographic information of children and parents was also determined. Statistical analysis included, kruskal-wallis, t-test and linear regression.
Results: The average score of the quality-of-life questionnaire was 66.42±17.91. No significant correlation was found between the mean quality of life of parents and dmft index. (p=0.916, r=0.008) A significant difference was observed between the child's dental caries and the father's age and education. (p<0.05) There was no significant difference in the mean dmft index, 5.32±0.5 in boys and 5.85±4.7 in girls. (p=0.459)
Conclusion: This study showed that the general quality of life of parents and its sub-branches such as the place where the child lives, the social and physical health of the parents are not directly related to early dental caries in children.

Abstract
Background: Antibiotics are commonly prescribed drugs by dentists. Irrational use of these drugs can lead to unwanted drug side effects, such as drug resistance in addition to unnecessary costs. This research was conducted to determine the antibiotic prescription pattern by dentists of Ardabil City based on the international ATC/DDD system.
Methods: In this cross-sectional descriptive study, 250 prescriptions of patients referred to dentists in Ardabil during the second quarter of 2021 were examined. The information related to prescribed drugs includes: drug dose, frequency of drug use, number of drugs that were collected and completed in the dental offices and clinics of Ardabil city, and finally after converting the data into a certain daily dose based on the ATC-DDD system, acquired data was analyzed using One-way analysis of variance and Tukey's post hoc tests and SPSS version 21 software, the significance level was considered less than 0.05.
Results: Out of the total 250 reviewed prescriptions, 207 prescriptions (82.8%) contained antibiotics. Metronidazole (73.4%) and amoxicillin (70.5%), were the most antibiotic drugs prescribed by Ardabil dentists respectively. In all prescribed drugs, the DDD value was higher than the standard DDD value. There was no significant difference between men and women in terms of the number of copies (p<0.05). The highest frequency was related to the prescription of three drugs and the lowest frequency was related to the prescription of six drugs. In terms of pharmaceutical forms, 201 prescriptions (97.1%) were only oral drugs and 6 (2.9%) were both oral and injectable
Conclusion: The results showed that the amount of antibiotics prescribed in prescriptions was higher than the standard DDD and the number of drugs prescribed in prescriptions was also higher than the figure recommended by the World Health Organization.
