Abstract
Background and Aims: Use of computer and internet in our modern and digitalized society is an efficient tool to be up to date and fulfil the information gaps. The aim of this study was to evaluate the extent of computer and internet usage among dental students of Islamic Azad University, Tehran, in 2016.
Materials and Methods: This descriptive study for evaluating access and usage of computer and internet by dental students was done using a researcher-made questionnaire on 401 dental students. Validity and reliability (Kappa: 0.82) of the questionnaire was confirmed. Statistical analysis was done by SPSS22 using descriptive and Logistic regression analyses.
Results: More than 95% of the students had access to the computer and Internet. 45.6% of students reported their skills were in the basic level. The major use of computer among the students was internet but only 13.2% of students used Microsoft Office program. The students used the internet for dental subjects even monthly (34.9%) or weekly (29.4%). Only 9.7% of the students had participated in educational workshop for learning methods of research. The most limitation was internet velocity. Positive correlation was found among prospering ownership status (P<0.001), economic status (P=0.05), level of education semester (P=0.038) and the computer & internet usage (what’s more in terms of access and also in terms of improve information and knowledge).
Conclusion: Based on the results, a higher economic level, higher level of education, and property ownership made better access to the computer and Internet. However, computer skills should be more concerned in educational program.

Abstract
Management of internal root resorption is a challenge to the endodontists. If it is left untreated, it may lead to the destruction of the surrounding dental hard tissues. Despite, routine obturation techniques are often employed without considering the best technique to solve this problem. This study presented a case of internal root resorption and apical periodontitis affecting tooth 12 (FDI) in a 31-year-old female patient, with a history of crown preparation in that region. We managed it with EndosealMTA and gutta-percha. After 12 months follow up, the tooth was still symptomless and in function and healing of bone resorption occurred.

Abstract
Background and Aims: Fractures of the facial bones and jawbones could cause functional problems along with social and cosmetic problems. Various factors (including road accidents, assault, falling from height, sport injuries, and getting hit by a hard object) could cause these fractures. Collecting and reporting accurate epidemiologic data regarding the facial fractures are major steps toward planning preventive measures. The aim of this study was to collect the epidemiologic data regarding maxillofacial fractures in two referral centers (Shariati and Sina hospitals) in the city of Tehran.
Materials and Methods: The study was a cross-sectional retrospective investigation. All the necessary data were collected from the patients’ files and analyzed using SPSS 25.
Results: The present study pursued data of 454 trauma admitted patients in oral and maxillofacial surgery wards of Shariati and Sina hospitals in 1397 and 1398. These data showed that a number of 374 patients of all patients were men and the other 80 were women. The ratio of male patients to female patients was 4.5:1. In 290 of cases (64%), the fractures occurred as combined fractures and in 164 cases (36%), the fractures occurred as single fracture. These fractures happened mostly in the mandibular bone and in mandibular body, and the least of these fractures happened in Orbit. This study showed that there was a significant relation (with 95% confidence level) between the mandibular body fractures and mandibular angle fractures. This study also showed that there was another significant relation (with 95% confidence level) between the mandibular angle fractures and LeFort 2 fractures. In addition, this study also showed (by using k2 exam) a relation between the etiology of trauma and the number of fractures.
Conclusion: This present study showed that the maxillofacial fractures happened mostly in men much more than women. If we put motorcycle accidents and car accidents in a group together called road accidents, the most common etiology of maxillofacial fractures is road accidents. The results showed that the most fractures happened in the age range of 15-25 year old.

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: Nowadays, the best choice for replacing missing teeth are dental implants, however, failure is not unexpected. One of the factors that plays an important role in the implant failure is bacterial microleakage which could cause biological complication. The aim of this study was to compare the bacterial microleakage between the two types of implants.
Materials and Methods: In the present interventional study, SPI and Dentis implants were placed bilaterally in the premolar-molar area of the patients' mandible. One day and 14 days after the delivery of the crown, by removing the crown and removing the abutment, sampling was performed using a sterile paper cone from four areas. One day after sample culturing, the number of colonies was counted. All data were entered into SPSS 23 and were analyzed using independent samples t-test and paired t-test with a significance level of 0.05. |
Results: The amount of bacteria in
implant sulcus was significantly different between the two types of implants (P=0.003). After 14 days, the amount of bacteria in SPI implant sulcus significantly decreased more than Dentis implant sulcus (P=0.001). After 14 days, the amount of bacteria also decreased in all other areas which there were no significant difference between the two types of implants (P>0.05).

Abstract
Background and Aims: Today, academic stress and subsequent test anxiety is one of the most important problems for the last year of high school students. In addition to systemic effects, stress can affect the level of oral health by disrupting oral health behaviors. The aim of this study was to investigate the relationship between stress and variables related to oral health in the final year of high school students prior to University entrance exam.
Materials and Methods: In this descriptive-analytical study, the level of stress and variables related to oral health in 180 students of the final year of high school in Tehran, in three time periods during the academic year 2018-2019, were measured by a questionnaire and one clinical examination. Data were analyzed by Friedman, Bonferroni and Generalized Estimating Equations using SPSS software.
Results: As the exam approaches, some variables related to the oral health, such as toothbrush usage pattern, daily sleep, fast food frequency, and sweet snack consumption, changed (P<0.05). Daily sleep changes were significantly associated with the stress changes (P=0.022). According to the results of the Repeated Measures Analysis, significant changes were observed between the average score of the "Cognitive Error" aspect of three times (P<0.001). Also, according to the results of the Bonferroni Test, significant changes related to the difference in the average score of "cognitive error" 6 months and 3 months before the entrance exam (P<0.001), 6 months and 1 month before the entrance exam (P<0.001), and 3 months and 1 month before the entrance exam (P<0.001) were observed. In all three cases, as the time of the entrance exam approaches, the score of "cognitive error" had decreased significantly. Considering that the lower score in this index indicates a higher level of test anxiety, the closer we get to the entrance exam, the higher the level of test anxiety in the "cognitive error" dimension
Conclusion: The academic stress of the national university entrance exam can affect some oral health variables such as daily sleep, however, it is not related to other variables.

Abstract
Background and Aims: Atypical facial pain (AFP) is a chronic disease associated with local pain in the craniofacial area. A wide range of treatments including drug therapy, psychiatric methods and open surgery are used for its treatment. Opiorphin is a pentapeptide that can block pain and also has proven antidepressant effects. The aim of this study was conducted to investigate the opiorphin concentration in AFP patients and to compare it with healthy people.
Materials and Methods: This study was performed on 30 AFP patients and 40 healthy individuals. Unstimulated saliva was collected from both groups by spitting method. HAD-A (Hamilton Anxiety Test) and HAD-D (Hamilton Depression Test) questionnaires were completed for all patients and controls. Psychological interview with the patients and psychological analysis were performed to determine anxiety and depression scores. Data analysis was done using SPSS (ver.24) statistical software
Results: The subjects of two groups were homogeneous in terms of age and sex. The mean salivary opiorphin concentrations in the case and control groups were 1.8050±0.2923 and 1.8032±0.3682 ng/ml, respectively. According to the results of t-Test, no significant difference was observed in the mean opiorphin concentration between the AFP group and control group (P=1.000). According to the Pearson's test, no significant relationship was found between the opiorphin levels and the age, sex, and anxiety or depression score in the patient and control groups (P>0.05). Also, there was no remarkable correlation between initial VAS, duration of pain and previous treatments with opiorphin levels in the AFP patients (P>0.05). No significant correlation was found between the opiorphin concentration and menopausal period in the case and control women (P>0.05).
Conclusion: The results showed that most AFP patients had some degree of anxiety and depression. However, salivary opiorphin concentration did not significantly increase in the AFP patients.

Abstract
Background and Aims: The incisive canal cyst also known as nasopalatine duct cyst (NPDC) is the most common developmental non odontogenic cyst and it is usually asymptomatic with a well corticated round, ovoid or in some cases unique heart shaped radiolucent radiographic finding. Its accurate diagnosis from odontogenic cysts, odontogenic tumor, and benign non-odontogenic tumors using clinical and radiographic findings leads to eradication of pathologic condition with minimum residual defects and patient discomfort. In this case report, the clinical and radiographic findings of a 60-year-old female with the chief complaint of swelling was reviewed. There were typical histologic and radiographic findings related to nasopalatine duct cyst. The surgical management is explained. Follow up visit showed satisfactory healing and no dehiscence. It could be suggested that heart shaped radiographic finding in 3-D reconstructed image in the maxillary midline would be a good predictor for NPDC.

Abstract
Background and Aims: The evaluation of the results of health transformation plan in dentistry, which started in March 2016 with the aim of improving oral and dental health, is extremely important in order to improve planning for future actions. Therefore, the purpose of the present study was to evaluate the effect of the health transformation plan on common oral health indices in Guilan province in Iran.
Materials and Methods: This cross-sectional analytical study was performed using the Health Deputy of Guilan University of Medical Sciences data and results of the general population and housing census of the 2010 and 2015. Data analysis was done using Ordinary Least Squares regression method, considering dependent variables including DMFT, dmft and periodontal disease indices (CPI) and independent variables including gender, education, urban or rural residence, percentage of 13-year-old population, illiteracy rate, fertility rate and being or not in the transformation plan, to investigate the difference between the two groups before and after the implementation of the transformation plan in terms of variables and to examine the relationship between independent and dependent variables. Finally, data were analyzed by STATA SE software version 15.
Results: The health transformation plan did not have a significant relationship with the change of DMFT and CPI 2 to CPI 6 indices, but had succeeded in reducing dmft and CPI1 (P<0.05), which reduction in CPI1 index was not desirable.
Conclusion: It seems that despite the extensive activities of the health transformation plan in dentistry in the field of prevention and treatment, there is still a need for more changes, especially in terms of culture and education. Also, there is need to provide more facilities for access to services by all sections of the society, especially the weak sections for healthcare.

Abstract
Background and Aims: The white color of teeth is one of the most essential factors in smile esthetics. Therefore, various whitening agents such as bleaching mouthwashes have been produced in response to the people’s high demand for having whiter teeth. The present study evaluated the efficacy of three whitening mouthwash products on tooth enamel whiteness.
Materials and Methods: In the present in vitro study, 32 bovine incisors were assigned to four groups in terms of the mouthwash used (n=8): control (C); Xenon Smart White (ZSW), containing pyrophosphate and triphosphate; Signal White Now (SWN), containing Blue Covarine; and Pasta Del Capitano whitening mouthrinse (PCW), containing Plasdone. Colorimetry was carried out using a spectrophotometer at the baseline and 2, 4, 8, and 12 weeks after treatment with mouthwashes. Data were analyzed using CIELab parameters with ANOVA, RM two-way ANOVA, and post hoc Tukey tests (α=0.05).
Results: The results showed that the whiteness created by the SWN mouthwash was clinically visible (ΔE>3.3). However, the functions of all the mouthwashes were statistically similar with no significant differences from the control group (P>0.05).
Conclusion: Although, Blue Covarine-containing mouthwash was somewhat effective in whitening of tooth enamel, none of the mouthwashes had significant efficacy compared to distilled water.

Abstract
Background and Aims: The bond strength of direct composite restoration to the caries affected dentin is a challenging issue. Preparation of dentin with an antibacterial agent is a method for creating durable bonded restorations. The aim of this study was to investigate the effect of curcumin photosensitizer on the bond strength of a universal adhesive to the caries-affected dentin (CAD).
Materials and Methods: In this experimental in vitro study, forty-four decayed human molar teeth were selected. After removing the surface enamel and dentin by a water-cooled saw, the decayed mid-coronal dentin was stained with a caries detection solution. The green and soft infected dentin was removed and CAD and hard and healthy surrounding dentin were left. Then, the remaining dentin surfaces were treated by 600 grit silicon carbide papers and polished. The specimens were divided into two groups (n=22): dentin pretreatment group by curcumin and control with no dentin pretreatment group by curcumin. Each group was divided into two subgroups based on the method of application of All-Bond Universal adhesive (Bisco, USA) (etch and rinseand self-etching methods). After placing the Aelite All Purpose Body (Bisco, USA) composite, all specimens were placed in a universal testing machine for microshear bond strength (µSBS) test. The failure mode of the isolated surfaces was evaluated under a stereomicroscope. Two-way ANOVA analysis was used for statistical analysis.
Results: Based on the obtained results, intervention with the adhesive application method and surface pretreatment with curcumin had no significant effect on the bond strength. Also, there was no significant difference in the bond strength of the curcumin group in both etch and rinse and self-etching methods (SE=56.3±27.11 MPa; ER=52.4±84.11 MPa) (P=0.847). In the curcumin-free group, there was no significant difference between the two different adhesive application methods (P=0.187).
Conclusion: The results obtained in the present study showed that the pretreatment of dentin affected by caries with light-sensitive curcumin and also use of a universal adhesive by either self-etching or self-etchinf methodshad no influence on the microshear bond strength of the composite restoration.

Abstract
Background and Aims: Using fissure sealant is one of the most effective methods of preventing pit and fissure decay. Fluoride has been added to various materials as a known anti-caries agent. Fluorinated graphene (FG) has gained attention due to its unique properties. The specific structural characteristics of graphene fillers, besides having antibacterial properties by increasing the rate of fluoride release and charge and neutralizing the acidic pH of the environment, is a suitable option in many treatments. This study investigated the effect of addition of fluorinated graphene nanoparticles on the fluoride release in Fissurit®, a commercial fissure sealant.
Materials and Methods: In this in vitro study, fluorinated graphene oxide (FGO) with bright white color was prepared. After synthesis, 0, 1, 2 and 4 by weight percent were added to the fissure sealant (Fissurit®). Then, the release of fluoride in this material was measured and compared with the commercial fissure sealant containing fluoride (Fissurit®).
Results: According to the obtained results, the amount of fluoride released from groups with different percentages of FGO had a direct relationship with the percentage of FGO addition. Also, at different times, there was a significant difference between the groups with FGO and the control group without FGO (P<0.001).
Conclusion: Addition of FGO to the fluorinated fissure sealant caused the release of fluoride and the possibility of recharging it. The power of releasing fluoride and its recharging in fissure sealant with FGO was higher than the fluorinated fissure sealant, but its fluoride was discharged at a faster rate.

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.

Abstract
Background and Aims: Due to their professional nature, dentists and nurses are in close proximity with patients and the droplets of infected patients can increase the risk of cross-transmission and viral diseases, especially COVID-19. Therefore, the purpose of this study was to evaluate the level of anxiety and awareness of the final two-year nursing and dental students at Isfahan University of Medical Sciences regarding COVID-19.
Materials and Methods: This descriptive, analytical, and cross-sectional study examined all the students studying in the last two years of dentistry and nursing, Beck Anxiety Inventory and online awareness questionnaire available to students were placed. The variables of this research included year of study, major, anxiety, and awareness. After collecting data using chi-square test and frequency distribution tables, the results were analysed using SPSS software version 23 and at an error level of 0.05.
Results: 429 students participated in the study, most of them were nursing students (58.7%) and the highest frequency of students was from the entry year of 2018 (29.6%). The average anxiety of nursing students in 2017 entry was 31.12 at severe level and in 2018 entry was 28.53 at moderate level. The average anxiety of dental students in 2015 entry was 33.93 at severe level and in 2016 entry was 36.65 at severe level. Also, the level of knowledge of nursing students was higher than that of dental students in most of the examined questions about corona virus and a significant difference was observed between students (P<0.05).
Conclusion: The level of awareness of nursing students was higher than that of dental students, and the level of anxiety in dental students was high. Recognizing the limitations of this cross-sectional study, itcan be concluded that only a small number of dental students had good knowledge about COVID-19. Students who had a higher year of education gave more correct answers. It is important to strengthen the knowledge about biosafety during the professional training of dental students in order to reduce the risks of contamination and cross-infection during patient care. It would be necessary to hold training courses to increase the level of awareness and to reduce students' anxiety.

Abstract
Background and Aims: Educational planning is one of the main areas of education and training, which plays an essential role in the optimal training of human resources. The aim of this study was to compare the educational program (curriculum) of general dentistry in Iran with that of several prestigious dental schools in the Middle East countries.
Materials and Methods: This is a descriptive comparative study using the dental education curricula of six prominent countries in the Middle East in the field of dental sciences. Their selection was based on similarities and common cultural, economic and social characteristics. After collecting the selected curriculums, four steps including description, interpretation, juxtaposition and comparison were done. Tables were drawn based on goals such as the number of years of education, mission, general goals, and the role of graduates in the medical system of that country.
Results: The educational curriculum of the countries reviewed in the Middle East have many similarities in terms of the number of years of study in the field of dentistry, the general mission and goals, and the role of students in the medical system of that country. The main differences were in the number and type of teaching units in the curriculum of this countries. The method of teaching and the distribution of topics in the curricula of the countries differentiated them from each other. According to the results of this study, the curriculum of the countries of Iran, Saudi Arabia and the UAE were the most similar among the countries of the Middle East. The teaching method and distribution of topics in the curricula of countries distinguished them from each other.
Conclusion: Countries that are based on Russian language education have a shorter number of years of education and are similar to Russia. However, countries with an American educational base such as Saudi Arabia, the United Arab Emirates, and even Iran have a longer academic years and more general similarities in educational content.

Background and Aims: Given the risks of repeated exposure to ionizing radiation in dentistry and its potential adverse effects on the health of patients, staff, and students, adherence to radiation protection principles is a fundamental priority in this profession. This study aimed to assess the knowledge, attitudes, practice, and behavioral predictors of dental students at Arak University of Medical Sciences regarding the radiation protection principles in 2024.
Materials and Methods: This cross-sectional analytical study was conducted as a census on 120 dental students during October 2024 to March 2025. Data were collected using a structured questionnaire, which included sections on demographic information, knowledge assessment (maximum score: 20), attitudes (maximum score: 55), and practice (maximum score: 16). The questionnaire used was a revised version of a standard instrument, the validity (CVR=0.62, CVI=0.79) and reliability (Cronbach's alpha >0.7 for all sections) of which were measured and confirmed. Data analysis was performed using SPSS27, with analytical tests including the Mann-Whitney U test, Kruskal-Wallis test, Spearman’s correlation, and predictive practice with asses test of linear regression.
Results: The number of 120 students with mean age of participants 23.59 ± 3.13 old years and 51.7% were male. The mean scores were as follows: knowledge (9.69 ± 2.51), attitude (27.88 ± 3.05), and practice (12.60 ± 1.06). A significant difference in knowledge was observed between the male and female students (P=0.035), which the male students’ scoring was higher. No significant differences were found in the attitude or practice between genders (P>0.05). Factors such as place of residence (dormitory or non dormitory), prior radiation protection training, age, GPA, and admission year showed no significant association with the knowledge, attitude, or practice (P>0.05). Based on the regression model, the greatest predictors of student performance were age (R2=0.247, P=0.015) and grade point average (R2=0.282, P=0.003).
Conclusion: While academic training effectively imparts knowledge of radiation protection, translating this knowledge into practical performance remains moderate and thus, highlighting the need for advanced hands-on training courses.
