Abstract

Background and Aims: Numerous researches have been conducted in the field of dental public health in the country so far, and therefore the purpose of this study was to investigate the distribution of studies conducted in this field in terms of quantity and coverage of different subjects.
Materials and Methods: This study was conducted in 4 phases in Iran in 2023. The initial phase or the comparative study was to extract the doamins and sub-domains related to the dental public health studies, types of the research dissemination models, and the list of researchers in this field. The second phase included holding virtual Delphi meetings with researchers to finalize the information collecting checklists including the domains and sub-domains. In a virtual group of about 140 researchers, the domains and their proposed sub-domains were discussed and revisions continued until consensus was reached. In the third phase, the necessary data were collected and entered into the forms. The main source for data collection was google scholar profile. The final phase included the design of the system in the Access program for archiving and classifying information with the ability to search and report. Finally, the frequency and relative frequency of research titles were categorized according to the topic and the university conducting the research and the reports presented in the form of graphs and tables.
Results: Based on the first and second phases of the study, the selected model had 6 domains and 11 sub-domains. Epidemiology with the largest share (35%) was first rank, and the health system (30%) and health promotion (19%) ranked second and third, respectively. Ethics (1%) was at the lowest rank. Universities of Tehran (33%), Isfahan (25%) and Shahid Beheshti (22%) had the most publications in the field of community oral health. In the domian of epidemiology, oral health surveys with 204 articles (74%) and oral health risk factors with 69 articles (26%) were the highest number of published articles.
Conclusion: Some sub-domains of the community oral health filed are not well covered that might interrupt their application to improve the oral health situation in the country.

Abstract

Background and Aims: Oral health literacy plays an important role in reducing oral health disparities. Evaluation of oral health literacy can be done at individual and population levels. This study was conducted with the aim of investigating oral health literacy among students of Shiraz University of Medical Sciences in 2023.
Materials and Methods: This study was descriptive, applied and cross-sectional. The research population included the students of different academic levels of Shiraz University of Medical Sciences, except the final semester students. The sample size was calculated based on the total number of students studying at different levels at Shiraz University of Medical Sciences in the second half of the academic year in 2023 using an appropriate statistical formula. Sampling was done in a stratified-random manner according to faculty, field, and level of education. The oral health literacy of the participants based on education level, age, and gender was measured by the oral health literacy adult questionnaire (OHL Adults Questionnaire: OHL-AQ). Data analysis was done using SPSS 27 software and descriptive statistics (mean, standard deviation, percentage), independent t-test, Kruskal-Wallis, and Tukey test.
Results: The findings indicated that the average oral health literacy score of students was 14.75±1.37. Also, there was a statistically significant relationship between the average oral health literacy score of students and the parameters of education level, gender, and age of students (P-value < 0.05). This indictaed that the oral health literacy of students increased in the doctoral level and also with increasing age. In addition, the female students had higher oral health literacy.
Conclusion: Based on the results, the oral health literacy among Shiraz medical students was high. People with higher education level and age had higher level of oral and dental health literacy than people with lower education level and age. Oral and dental health literacy level was higher in girls than boys. It can be suggested that a 1) suitable platform be provided in order to improve the level of education of the society, leading to the improvement of the oral health literacy of the people; 2) regular dental examinations in order to increase the oral health literacy of the society is encouraged and promoted, especially in lower year students; and 3) research in effective training in the field of oral health literacy to increase the oral health literacy of people in the society.

Abstract

Background and Aims: Emotional intelligence helps dental students better manage stress and establish effective communication with patients, while self-efficacy strengthens their confidence in performing clinical tasks and acquiring professional skills. The connection between these two factors leads to improved academic and professional performance. The aim of this study was to examine the relationship between the emotional intelligence, self-efficacy, and academic success among dental students.
Materials and Methods: This cross-sectional study included 55 dental students from Shahid Beheshti University of Medical Sciences - Iran, selected by convenient sampling. To measure academic self-efficacy beliefs, the Sherer questionnaire was used, which consisted of 17 questions with a theoretical score range of 17-85. To measure emotional intelligence, the Bar-On questionnaire was used, consisting of 90 questions with a theoretical score range of 90-450. Academic achievement was assessed using the students' grade point average (GPA). Additionally, gender, living at home or in a dormitory, and parental education levels were considered as background variables. The data were analyzed using descriptive statistics, t-tests, and Pearson correlation coefficient.
Results: Among the 55 students who participated in this study, including 30 women and 25 men, the average emotional intelligence score was 84.85, the average self-efficacy score was 62.02, and the average GPA was 16.42. There was a significant difference in the emotional intelligence scores based on gender and living situation, with male students scoring higher than female students and dormitory residents scoring higher than those living at home (P=0.02). There was no significant difference in the self-efficacy scores and GPA between males and females. Students whose mothers had higher levels of education and those living at home had higher GPAs (P<0.03). No statistically significant relationship was found between the academic success and emotional intelligence or self-efficacy (P>0.05).
Conclusion: The findings suggest that while emotional intelligence and self-efficacy may not directly influence academic success, other factors like living environment and parental education can play a role. Understanding these dynamics can help educators focus on holistic student development, addressing not just academic skills but also personal and social factors that contribute to student performance and well-being.

Abstract

The rapid integration of artificial intelligence (AI) into various aspects of human life raises important questions about its potential benefits and drawbacks. As AI reduces our reliance on cognitive processes, we must consider its long-term effects on human cognition. While, the general use of AI is still relatively new, significant discussions and studies have begun to explore its impact on cognitive function. This letter aims to summarize findings from several studies, highlighting the dual nature of AI's cognitive effects and the necessity for a balanced and targeted approach to its use.
Some studies indicated that AI could enhance cognitive abilities. For instance, Haider et al. (1) conducted a cross-sectional study revealing that AI tools such as memory enhancement platforms and adaptive learning systems improved short-term and long-term memory, analytical thinking, and decision-making efficiency. A review (2) also found that AI-based interventions like brain training programs, promoted neuroplasticity and alleviate anxiety, particularly in older adults.
Conversely, another research highlights the negative effects of AI on cognitive function. Zhai et al. (3) conducted a systematic review demonstrating that prolonged use of AI conversational systems in education could hinder independent problem-solving and analytical reasoning, introducing risks such as algorithmic bias, privacy violations, and plagiarism. Furthermore, excessive reliance on AI has been linked to diminished critical thinking, creativity, and work ethic, potentially fostering psychological dependence and reducing motivation for deeper learning (1). Increased screen time and reliance on AI may also alter brain structure, resulting in reduced gray matter in frontal regions and impairing attention, memory, and socioemotional regulation (2).
The impact of AI varies across different age groups. In children, unsupervised AI use can impede language development and attention span. Among young people, social media and AI tools may contribute to anxiety, loneliness, and poor academic performance. For older adults, while cognitive training through AI shows promise, it necessitates support for digital literacy (2).
In summary, while AI can enhance cognition in certain contexts, its unchecked use poses risks to creativity, independent thinking, and ethical standards. For optimal outcomes, AI usage should be accompanied by human judgment and critical thinking skills must be integrated, and also overall screen time should be monitored and limited. Future research should prioritize prospective studies and develop specific guidelines for AI users across different ages and demographic groups, including students.

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: Substance abuse is recognized as a serious public health issue. The aim of this study was to comprehensively assess the correlation between the substance use and oral health status  as well as its impact on the quality of life of addicts in a multi-center approach.
Materials and Methods: In this cross- sectional and analytical study in year 2023, individuals with a history of addiction who visited addiction treatment centers in Isfahan province were recruited conveniently and examined through questionnaires (about demographic information, methods of substance use, oral health behaviors, the use of dental services, and perceived oral health) and clinical examinations. The oral health-related quality of life (OHQOL) was assessed using the OHIP-14 questionnaire. Clinical examinations assessed DMFT, gingival index, mucosal lesions, temporomandibular joint disorder, and treatment needs of the individuals. Data were analyzed using ANOVA, t-tests, and linear regression models (α=0.05).
Results: 232 individuals with age of 45 ± 9.9, mostly male (94.8%) and married (68.5%) were recruited. About 50% of individuals never brushed their teeth. A total of 123 individuals (53%) used substances with moderate harm intensity (opium, hashish and cannabis). Pigmentation was the most common oral lesion. The mean DMFT was 19.27 ± 3 and the perceived oral health mean was 4.53 ±2.98 (out of 10). A total of 187 individuals (80.6%) required prosthetic treatment. The mean OHQOL was 15.93 ± 11.6. Functional limitation had the lowest (1.53), and psychological discomfort had the highest score (3.31) among the seven domains of OHQOL. The linear regression model (P<0.001 and R2=24%) found that the use of high-risk psychoactive substances, oral health behaviors, and age contributed to changes in DMFT. The OHIP linear regression model (P<0.001 and R2=36%) revealed that the duration of addiction, perceived oral health, age, self-employment, government jobs, and retirement contributed to changes in OHIP.
Conclusion: Compared to the general population, addicts have poorer oral health behaviors and more oral health problems, which significantly reduce their oral health-related quality of life.

Abstract

Background and Aims: Oral health affects the quality of life and plays the main role in achieving optimal conditions of health and general well-being. Therefore, this study was conducted with the aim of investigating the psychosocial effects and quality of life related to oral health in patients treated with composite veneers.
Materials and Methods: In this cross-sectional study, 48 patients who referred to the restorative department of Jundishapur University of Ahvaz for composite veneer treatment were participated. The PIDAQ questionnaire was used to investigate the aesthetic effects of composite veneer treatment on the psychosocial conditions of the patients, and the OHIP-14 questionnaire was used to investigate the quality of life related to oral health. Patients were asked to complete both questionnaires before treatment and one month after composite veneer treatment. Also, demographic information including age, sex, education and marital status of the patients were recorded. The purpose and benefits of participating in this study were fully explained to the patients and the patients voluntarily participated in this study. Then, an informed consent form was given to the patients. In order to compare the scores before and after the treatment, the paired T-test and its non-parametric equation expression (Will-Coxon) were used, and P<0.05 was considered.
Results: According to the results, the average age of the respondents was 28 years. In terms of gender, 54.2% of the patients were male, and in terms of education, most of the participants in the study had a bachelor's degree (35.4%). The total score of OHIP-14 before treatment was 26 and after treatment 22. Also, the total score of PIDAQ before treatment was 49 and after treatment 28. Comparing the scores of psychosocial effects and quality of life related to the oral health before and after composite veneer treatment showed that there was a difference between the average score of psychosocial effects and quality of life. There was a significant difference related to the oral health before and after composite veneer treatment, which significantly decreased after treatment (P<0.05).
Conclusion: The present study showed that suitable veneer composite treatments could improve the oral health related to the quality of life of people. Also, treatment with composite veneers could have a significant effect on patients' self-confidence. Composite veneers could reduce social effects, psychological effects, and cosmetic concerns related to patients’ teeth.

Abstract

Background and Aims: Pharmacies can serve as an appropriate setting for the provision of oral health care, including preventive services, early detection, and referrals. The present study aimed to assess the awareness, performance and oral health behaviors as well as self-perceived oral health among pharmacists and pharmacy staff in Isfahan.
Materials and Methods: This cross-sectional study was conducted in 2024 using a random sampling method across pharmacies in Isfahan. In total, 176 pharmacists and pharmacy staff completed a standard self-administered questionnaire in person, regarding their awareness, performance, and behaviors related to oral health, as well as their self- perceived oral health. Data were analyzed using Chi-square test, Mann–Whitney U test, and Spearman correlation coefficient in SPSS software version 27 (P<0.05).
Results: Oral health knowledge was rated as poor in 34 individuals (19.3%), moderate in 89 (50.6%), and good in 53 (30.1%). Pharmacists’ knowledge score was significantly higher than that of other pharmacy staff (P=0.002). The most commonly reported service provided to clients by participants was offering analgesics for pain relief (61.9%). While, less than half of the participants reported providing information on oral hygiene (36.9%) or referring clients to a dentist (40.9%). Oral health behaviors including brushing teeth at least twice a day (80.4%), regular use of fluoride toothpaste (97.2%), visiting a dentist during the past year (55.1%), and non smoking (67.0%) were favorable among most participants. However, flossing (50.6%) and frequent snacking (65.3%) were unfavorable in majority of individuals.
Conclusion: Considering the moderate level of oral health knowledge and the presence of some unfavorable behaviors such as insufficient use of dental floss and frequent snacking, it is recommended to implement educational programs to improve knowledge and promote positive oral health behaviors
