Effects of educational interventions based on the theory of planned behavior on oral cancer-related knowledge and tobacco smoking in adults: a cluster randomized controlled trial.

BACKGROUND: The theory of planned behavior (TPB) is an effective model for facilitating behavioral change. The aim of the present study was to evaluate the impact of TPB-based educational interventions on oral cancer-related knowledge and tobacco smoking behavior in an Iranian adult population in 2022. METHODS: In this randomized controlled trial, a total of 400 healthy individuals were enrolled. The study was implemented in 20 urban health centers in the south of Tehran, Iran. The health centers were randomly allocated into two intervention groups. In group PowerPoint (PP), the participants received education through a 20-minute PowerPoint presentation complemented by a pamphlet. Group WhatsApp (WA) was educated via WhatsApp messages and images. Data was collected using a structured questionnaire at baseline, and at one- and three-month follow-ups. The outcomes were evaluated in terms of knowledge, tobacco smoking behavior, and the related model constructs i.e. intention, attitude, subjective norm, and perceived behavioral control. Generalized estimating equations (GEE) regression models were applied to assess the effect of interventions on repeated measurements of the outcomes. All analyses were conducted using STATA Software Version 17. RESULTS: Out of all the participants, 249 (62%) were women. The mean and standard deviation (SD) of age were 39.67 and 13.80 years. Overall, group PP had a significantly higher score of knowledge compared to group WA (ß = 0.43, p = 0.005). No significant differences were found between the groups with regard to tobacco smoking and the related TPB constructs, except for attitude with a higher score in group PP compared to group WA (ß = 0.50, p = 0.004). At the three-month follow-up, both interventions had significant effects on increasing knowledge (ß = 4.41), decreasing tobacco smoking (OR = 0.54), and increasing intention (ß = 1.11), attitude (ß = 1.22), subjective norm (ß = 1.37), and perceived behavioral control (ß = 1.08) (P < 0.001). CONCLUSIONS: Both interventions were effective in improving knowledge, tobacco smoking, and the TPB constructs after three months. Therefore, the application of both methods could be considered in the design and implementation of oral cancer prevention programs. TRIAL REGISTRATION: The trial protocol was registered in the Iranian Registry of Clinical Trials (IRCT) on 04/03/2022 (registration number: IRCT20220221054086N1).

Dental service utilization and the COVID-19 pandemic, a micro-data analysis.

BACKGROUND: Global crises and disease pandemics, such as COVID-19, negatively affect dental care utilization by several factors, such as infection anxiety, disrupted supply chains, economic contraction, and household income reduction. Exploring the pattern of this effect can help policy makers to be prepared for future crises. The present study aimed to investigate the financial impact of COVID-19 disruptions on dental service utilization. METHODS: Data on the number of dental services offered in Dental School Clinics of Tehran University of Medical Sciences was collected over a period of two years, before and after the initial COVID-19 outbreak in Iran. School of Dentistry operates two clinics; one with competitive service fees and one with subsidies. Regression analyses were performed to determine the effect of the pandemic on the number of dental services divided by dental treatment groups and these clinics. The analyses were adjusted for seasonal patterns and the capacity of the clinics. RESULTS: There was a significant drop in dental services offered in both clinics across all dental groups in the post-COVID period (on average, 77 (39.44%) fewer services per day). The majority of the procedure loss happened in the Private clinic. Adjusting for seasonal patterns and the service capacity, regression results documented 54% and 12% service loss in Private and Subsidized clinics following the pandemic, respectively. Difference-in-difference analysis documented that the Subsidized clinic performed 40% more treatments than the Private clinic in the post-COVID period. CONCLUSIONS: Pandemic -reduction in dental care utilization could have long-term ramifications for the oral health of the population, and policymakers need to provide supportive packages to the affected segments of the economy to reverse this trend.

Community-based dental education in Iranian dental schools.

BACKGROUND: Community-based dental education (CBDE) has been an essential advancement in dental education in recent decades, enhancing it in many aspects. This study aimed to determine the characteristics and improvements of CBDE in dental schools in Iran. METHODS: In the present descriptive study, an electronic questionnaire, including 18 "yes/no", "multiple choice", and "short answer" questions about the nature and extent of CBDE and students' experience in CBDE, was used. In early 2021, the questionnaires were mailed to the deans of all 43 dental schools in Iran under the supervision of the Council for Dental Education of the Iranian Ministry of Health and Medical Education. Reminder calls were made after 6 and 12 weeks. Dental schools that did not follow the CBDE program were excluded. The responses were analyzed descriptively. RESULTS: Thirty-six dental schools completed the questionnaire (response rate: 84%). Seventeen schools (47%) reported having CBDE in their dental program. Sites lacking a well-equipped dental setting were the most used out of all extramural sites. The number of weeks dedicated to CBDE ranged between 1 and 20 (median: 4). The most common dental procedures practiced in extramural sites were pediatric dentistry (100%), restorative dentistry (71%), and dental examination (59%). The student-to-supervisor ratio in CBDE ranged between 3 and 15 (median: 5). In most schools (65%), the staff involved in directing CBDE were Community Oral Health PhDs. CONCLUSIONS: An increasing number of Iranian dental schools have integrated CBDE into their undergraduate dental curriculum. The characteristics and extent of this educational strategy vary widely among dental schools. CBDE can be more effective by making positive changes in dental programs.

Knowledge of the health personnel involved in the fluoride varnish therapy programs of primary schools in Tehran, Iran.

INTRODUCTION: The World Health Organization (WHO) places great importance on oral health promotion programs in schools, given that approximately one billion people worldwide are students. This demographic not only includes the students themselves, but also extends to school staff, their families, and the broader community, all of whom are interconnected. The objectives of this study were firstly to assess the knowledge of health personnel conducting fluoride varnish treatment (FVT) in schools, and secondly to solicit their views on the effectiveness of their training methods. METHODS: Data was collected from health personnel involved in FVT in schools, supervised by medical universities in Tehran province, using a questionnaire. The questionnaire was divided into four sections: demographic information, methods of receiving FVT training, respondents' knowledge regarding FVT, and opinions about the effectiveness of FVT training methods. The questionnaire was distributed via social media, phone conversations, and email. The collected data was analyzed using Mann-Whitney in SPSS Version 26. A regression model was also fitted to the data. RESULTS: The present study included 403 participants. Among various educational methods, it was found that participation in previous workshops (P = 0.001) and FVT workshops (P = 0.013) was significantly correlated with a higher FVT knowledge score. Additionally, participation in previous oral health promotion programs was significantly associated with a higher knowledge score (P < 0.05). Therefore, a history of participating in previous health promotion programs significantly contributed to the participants' knowledge. CONCLUSION: Participation in previous oral health programs was found to be significantly correlated with a higher knowledge score. The effectiveness of training programs can be attributed to participation in previous workshops and FVT workshops. This study provided insights into potential strategies for enhancing personnel training in national oral health programs.

Effectiveness of two educational interventions based on the theory of planned behavior on oral cancer self-examination in adults: a randomized controlled trial.

BACKGROUND: The theory of planned behavior (TPB) is recognized as an effective theory for behavior change. The aim of the present study was to investigate the impact of two TPB-based educational interventions on oral self-examination (OSE) behavior and the related TPB constructs among adults in Tehran, Iran, in 2022. METHODS: This randomized controlled trial involved 400 healthy individuals recruited from 20 urban comprehensive health centers in the southern part of Tehran, Iran. The health centers were randomly assigned to two control (PowerPoint) and intervention (WhatsApp) groups (200 individuals in each group). In the control group (the recipient of the routine care), participants received a 20-minute lecture through a PowerPoint presentation and a pamphlet. In the intervention group (the recipient of an additional intervention alongside the routine care), participants were educated through messages and images on WhatsApp along with having monthly group discussions. Data was collected at baseline, as well as at 1- and 3-month follow-ups using a structured questionnaire. The outcomes assessed included OSE behavior and the related TPB constructs: intention, attitude, subjective norm, and perceived behavioral control. Linear and logistic generalized estimating equations (GEE) regression models were used to evaluate the impact of the interventions with STATA version 17. RESULTS: Of the total participants, 151 (37.75%) were men. The mean ± standard deviation (SD) of ages in the PowerPoint and WhatsApp groups were 39.89 ± 13.72 and 39.45 ± 13.90, respectively. OSE and the related TPB constructs showed significant differences between the groups at the 1-month post-intervention assessment. The effect of PowerPoint was more significant in the short-term (one month), while both methods showed similar effectiveness after three months, specifically in relation to OSE and the TPB constructs. At the 3-month post-intervention assessment, there were significant increases in OSE (OR = 28.63), intention (ß = 1.47), attitude (ß = 0.66), subjective norm (ß = 2.82), and perceived behavioral control (ß = 1.19) in both groups (p < 0.001). CONCLUSIONS: The present study provides evidence of the effectiveness of both educational interventions in improving OSE and the TPB constructs after three months. Therefore, both TPB-based educational methods can be recommended for designing and implementing interventions aimed at preventing oral cancer. TRIAL REGISTRATION: The trial protocol was registered in the Iranian Registry of Clinical Trials (IRCT) on 04/03/2022 (registration number: IRCT20220221054086N1).

Factors associated with dental clinic use by clients in Nigeria during the COVID-19 pandemic.

BACKGROUND: Nigeria, like many other countries, faced challenges in dental care provision during the COVID-19 pandemic, necessitating limited care to emergencies only. However, the impact of restricted access to dental services on oral health remains a concern, particularly with preventive maintenance care. This study aims to identify the factors associated with dental service utilization during the COVID-19 pandemic among patients attending dental clinics in Nigeria, and their sources of information about COVID-19. METHODS: This cross-sectional study recruited 500 participants who had visited dental clinics before and during the pandemic. Data were collected through telephone interviews and online questionnaires between September and December 2021. Inferential analyses were conducted using ordered logistic regression models to assess the association between the independent (awareness of emergency dental treatments, knowledge of COVID-19 transmission routes in dentistry, awareness of required preparations in dental practice settings, fear of COVID-19 infection in dental settings), and dependent (utilization of dental services during the pandemic) variables after adjusting for confounding variables (age, sex, educational status, COVID-19 vaccinations status and COVID-19 status of live-in residents). The sources of COVID-19 information by dental patients was also identified. Statistical significance was established at 95% confidence level with a p value < 0.05. RESULTS: Many participants were males (51.2%) and had tertiary education (61.6%). Fear of COVID-19 infection in dental settings was significantly associated with lower odds of utilizing dental care services during the pandemic (Adjusted Odds Ratio: -0.06, 95% Confidence Interval: -0.08, -0.01). The main sources of COVID-19 information were mass media and social networks, with only 42% receiving information from dental professionals. CONCLUSION: Fear of COVID-19 infection in dental settings significantly influenced dental service utilization during the pandemic. Strategies to address fear and improve communication channels between dental professionals and patients are essential for promoting oral health during similar crises.

Evaluation of national dental curriculum in Iran using senior dental students' feedback.

BACKGROUND: Dental curriculums require regular revision to stay up to date in scientifical and societal fields. Senior dental students are among the main stakeholders of such curriculums. The present study investigated the opinions of Iranian senior dental students regarding the adequacy of their dentistry program and the national dental curriculum in training a competent dentist, the program's content, and its structure. METHODS: A previously designed and validated questionnaire on the opinion of senior dental students regarding curriculum adequacy was sent to a representative in each of the country's dental schools. Before the COVID pandemic terminated data collection, a total of 16 schools (438 students) managed to respond (37%). The questionnaire asked the students to assess the adequacy of the training received in curriculum's theoretical and practical competencies with the help of a five-point Likert scale that ranged from "Completely inadequate" to "Completely adequate". It also questioned them on its teaching methods and intensity. SPSS software version 24 and Chi-square test served for statistical analysis. RESULTS: In total, the study has 438 participants, 245 female and 193 male. Significant sex differences were spotted in the responses concerning both theoretical and practical training. Regarding general training adequacy, 50 (22.6%) female students and 50 male ones (30.7%), P = 0.08 agreed that the program was acceptable. The numbers for students of old (more than 15 years of activity) and new schools were 47 (21.7%) and 53 (31.7%), respectively (P = 0.03). Nearly one-third deemed the teaching methods appropriate. Regarding the duration of curriculum phases, 33 students (8.3%) believed that basic science required extension, while 108 (28.6%) and 266 (69.1%) reported such need for pre-clinical and clinical phases. The school's years of activity emerged as significant, as 38.1% of students from new schools versus 21.7% of those from old ones deemed the extension of pre-clinical phase necessary (P < 0.001). CONCLUSION: A significant number of Iranian senior dental students found the undergraduate dental curriculum inadequate regarding competencies, content, and teaching. Further investigations will determine whether it's the curriculum or its implementation that warrants revision.

Are Iranian graduating dental students prepared to act as future role models of good oral health behaviour? A 10-year study.

INTRODUCTION: Dentists by their professional knowledge of prevention have a key role in providing a positive role model for oral health-promoting behaviours. We aimed to investigate the health behaviour of Iranian senior dental students in terms of oral self-care and tobacco use during a 10-year period to assess their preparedness to act as role models for health-promoting behaviours. MATERIALS AND METHODS: The study was performed in six dental schools selected through stratified cluster random sampling to have a representative sample of all dental schools in Iran. Data were collected in four occasions in 2005, 2008, 2011 and 2015. Senior dental students (N = 1188) were invited to voluntarily complete a self-administered anonymous questionnaire about their oral self-care and tobacco use. Recommended tooth-brushing habit (RTH) was defined as at least twice a day brushing with fluoridated toothpaste. Three separate questions about cigarette, pipe and waterpipe use were applied to assess the students' reported use of tobacco. RESULTS: The response rate was 81%. Female students reported more frequently RTH than males (p < .001). The reported RTH was more prevalent among nonsmokers. In 2005, 2008, 2011 and 2015, 22.5%, 26%, 28.5% and 24.6% of the students reported smoking, respectively. The trend of reported smoking had the least variation among female students. This was true also for male students regarding RTH. CONCLUSION: The status and trend of oral self-care and tobacco use among Iranian dental students call for more emphasis on adopting health-promoting behaviours during dental education.

Impact of COVID-19 on dental education- a scoping review.

BACKGROUND: A new corona virus called COVID-19 and its epidemic has affected health care systems in many ways. There have also been significant changes in dental education. The present study summarizes the findings about dental education resulting from a scoping review of COVID-19 and dentistry. METHODS: First, a comprehensive search of five databases (Google Scholar, Medline through PubMed, Embase, Scopus, and Cochrane Central) was conducted with the keywords: COVID-19 and its equivalent terms, dentistry, education, oral, students, curriculum, and academics. Articles related to oral health and COVID-19 were searched. Then articles on the subject of dental education were screened and reviewed. RESULTS: Of the 1389 articles investigating COVID-19 and dentistry, 135 articles were related to dental education and its relationship with COVID-19. The most articles in this field were from the United States, India, and Saudi Arabia. Most of the articles were cross-sectional and then review articles. Based on the review the articles were divided into two main categories of changes and concerns, and opportunities and solutions. Moreover, the following themes were extracted: teaching-learning quality and methods, study career and how students are prepared, infection control policies, theses, exams and assessments, financial and economic security, students and staff's mental health, school's policies and curricula, knowledge of students and staff about COVID-19. CONCLUSIONS: Dental education now faces big challenges, some of which have never been experienced before. On the other hand, the epidemic has created opportunities for dental education as well. Most of these challenges and opportunities are the same around the world, and the findings of the present study can be a good help to overcome the challenges ahead as well as a good reference to find the right questions to be answered in future studies.

Qualitative exploration of barriers and facilitators of dental service utilization of pregnant women: A triangulation approach.

BACKGROUND: Pregnant women are vulnerable to a wide range of oral health conditions that could be harmful to their own health and future child. Despite the usefulness of regular dental service utilization in prevention and early detection of oral diseases, it is notably low among pregnant women. In this qualitative study, we aimed to explore barriers and facilitators influencing pregnant women's dental service utilization. METHODS: Using a triangulation approach, we included pregnant women (n = 22) from two public health centers, midwives (n = 8) and dentists (n = 12) from 12 other public centers in Tehran (Iran). Data was gathered through face-to-face semi-structured interviewing and focus group discussion methods. The analysis of qualitative data was performed using conventional content analysis with MAXQDA10 software. RESULTS: Reported barriers of dental service utilization among pregnant women were categorized under emerging themes: Lack of knowledge and misbelief, cost of dental care, physiological changes, fear and other psychological conditions, time constraint, dentists' unwillingness to accept pregnant women treatment, cultural taboos and lack of interprofessional collaboration. Solutions proposed by dentists, midwives and pregnant women to improve dental care utilization during pregnancy were categorized under three themes: Provision of knowledge, financial support and establishing supportive policies. CONCLUSIONS: Understanding perceived barriers of dental service utilization during pregnancy can serve as baseline information for planning and formulating appropriate oral health education, financial support, and legislations tailored for lower income pregnant women, midwives and dentists in countries with developing oral health care system.

Medical emergency management among Iranian dentists.

AIMS: More than 18,000 patients need medical emergencies management in dental offices in Iran annually. The present study investigates medical emergencies management among Iranian dentists. MATERIALS AND METHODS: From the list of the cell phone numbers of the dentists practicing in the city of Tehran, 210 dentists were selected randomly. A self-administered questionnaire was used as the data collection instrument. The questionnaire requested information on personal and professional characteristics of the dentists, as well as their knowledge and self-reported practice in the field of medical emergency management, and availability of required drugs and equipments to manage medical emergencies in their offices. RESULTS: Totally, 177 dentists (84%) completed the questionnaire. Less than 60% of the participants were knowledgeable about characteristics of hypoglycemic patient, chest pain with cardiac origin, and true cardiopulmonary resuscitation (CPR) practice. Regarding practice, less than one quarter of the respondents acquired acceptable scores. In regression models, higher practice scores were significantly associated with higher knowledge scores (p < 0.001). CONCLUSION: The results call for a need to further education on the subject for dentists. Continuing education and changing dental curriculum in the various forms seems to be useful in enhancement of the self-reported knowledge and practice of dentists. CLINICAL SIGNIFICANCE: To successful control of medical emergencies in the dental office, dentists must be prepared to recognize and manage a variety of such conditions. In addition to dentist's knowledge and skill, availability of necessary equipments and trained staff is also of critical importance.

Background Characteristics and Cognitive Factors as Determinants of Oral Health in Pregnant Women, Tehran, Iran: A Cross-Sectional Study.

Objectives: Pregnancy can lead to oral health issues, yet many women remain unaware of the potential negative impact on their pregnancy. This study aimed to assess the dental and periodontal health of pregnant women in Tehran, Iran, and identify its associated factors. Materials and Methods: A cross-sectional study was conducted with 221 pregnant women attending 12 randomly selected public health centers in Tehran, Iran. A self-administered questionnaire gathered data on background characteristics, oral health knowledge, and self-reported health. Periodontal status, oral hygiene, and dental health were assessed using bleeding on probing (BOP), simplified oral health (OHI-S), and decayed-missing-filled teeth (DMFT) indices. Statistical analysis included simple and multiple linear regression (P<0.05). Results: The participants' ages ranged from 18 to 42 years (mean: 27.9 years, SD: 5.5). On average, participants scored 4.1 out of 11 (SD: 1.7) for general oral health knowledge and 1.62 out of 4 (SD: 0.9) for knowledge about oral health during pregnancy. The mean DMFT was 8.28 (SD: 5.7), with 65.6% of women having fair oral hygiene according to the OHI-S. Participants reporting poor general health had more debris (B: 0.276, P=0.043), while those with higher general oral health knowledge had fewer missing teeth (B: -0.183, P=0.048). Conclusion: Despite partial free oral health care provided to pregnant women in Iran, the dental and periodontal conditions of the participants were unsatisfactory. Implementing motivational educational programs within the primary health care system could be instrumental in improving the oral health of pregnant mothers.

Patients' knowledge about dental emergencies, COVID-19 transmission, and required preparations in dental settings.

INTRODUCTION: The Coronavirus disease 2019 (COVID-19) pandemics negatively affected the delivery of dental care. The study objective was to assess the knowledge of emergency dental treatments, the transmission routes of COVID-19 in the dental settings, necessary precautions to prevent disease transmission, and the associations between demographic factors and the mentioned domains among Iranian dental patients. METHODS: This was a cross-sectional study conducted in October 2021. A systematic random sampling approach was used to select 244 participants who had sought services at the dental clinic of Tehran University of Medical Sciences before and during the pandemic. Data was collected using a combination of interviewer-administered and self-administered questionnaire. Three backward stepwise multiple logistic regression analyses were conducted to determine the associations between background factors (age, sex, education level, living status, history of dental visits, history of COVID-19 vaccination, and past COVID-19 infection) and knowledge about emergency dental treatments, knowledge about COVID-19 transmission routes, and knowledge about necessary preparations in dental settings. RESULTS: The mean (SD) scores for knowledge of emergency dental treatments, COVID-19 transmission routes, and essential preparations in dental settings measured on a 100-point scale were 77 (15.4), 84.2 (12.3), and 93.3 (12.1), respectively. Good knowledge of emergency dental treatments was associated with being under 55 years old (p = 0.03). Good knowledge of COVID-19 transmission routes was associated with living with individuals at a high risk of COVID-19 (p = 0.014) and having received the COVID-19 vaccine (p = 0.013). After adjusting for age, among participants aged 30 years and older, good knowledge of necessary preparations in dental settings was associated with being female (p = 0.012) and having received the COVID-19 vaccine (p = 0.001). CONCLUSIONS: Patients who sought care at the dental clinic of Tehran University of Medical Sciences had good knowledge about the transmission routes of COVID-19 and the required preparations in dental settings, and limited knowledge about dental emergency treatments.

COVID-19's psychological toll on oral health: A cross-sectional study in Iranian adults.

BACKGROUND: The Coronavirus disease 2019 pandemic increased global psychological distress, emotional distress, and sleep disturbances, all known risk factors for compromised oral health. Despite this, there is limited understanding of the impacts of these psychological factors on oral health in certain populations, including Iranians. Thus, the present study investigates the associations between sociodemographic characteristics, emotional distress, sleep pattern changes, tooth brushing frequency, and oral ulcer reports in a sample of Iranian adults during the Coronavirus disease 2019 pandemic. MATERIALS AND METHODS: This cross-sectional, web-based study collected data from Iranian adults between July and September 2022 using respondent-driven sampling. The Mental Health and Wellness questionnaire was used to gather information on sociodemographic characteristics, emotional distress, sleep pattern changes, toothbrushing frequency, and oral ulcer reports. Simple and multiple logistic regression served for statistical analysis. RESULTS: Among the 240 participants, comprising 164 females and 76 males, with a mean age of 35.3 years (±13.3), 28 individuals (11.7%) reported reduced tooth brushing frequency, and 35 individuals (14.6%) reported oral ulcers. Male gender (OR = 2.75, p = 0.016) and sleep patterns changes (OR = 2.93, p = 0.01) increased the likelihood of reduced tooth brushing frequency. Additionally, being younger than 30 (OR = 2.87, p = 0.025) and fearing coronavirus transmission (OR = 3.42, p = 0.009) increased the odds of oral ulcers. CONCLUSIONS: Male gender and sleep pattern changes were risk factors for reduced tooth brushing frequency among the present sample of Iranian adults during the Coronavirus disease 2019 pandemic. Additionally, being under 30 and fearing coronavirus transmission were identified as risk factors for oral ulcers in this population. To preserve and promote adults' oral health during public health crises, targeted educational initiatives, public health awareness campaigns, and integrated mental and oral healthcare approaches are encouraged.

Designing a Tool to Assess Professionalism among Dental Students.

Objectives: Professionalism is essential to a strong and trusted patient-doctor relationship, which is believed to potentially enhance patient compliance and treatment outcomes. The purpose of our study was to develop and conduct a psychometric analysis of an assessment tool to evaluate the professional behavior of dental students. Materials and Methods: The study was performed in the School of Dentistry, Tehran University of Medical Sciences. After providing a pool of various criteria to assess professionalism, an expert panel prepared the primary version of the tool. The tool was set in a questionnaire frame to explore the significance level and evaluation feasibility of each criterion. The questionnaire was completed by tutors of the "Medical Ethics" course (n=6). After necessary revisions, face and content validity were evaluated by giving the checklist to eight experienced dental educators to determine the relevance, clarity, and simplicity of the questions. In the second stage, the final checklist (37 items) was given to dental educators to evaluate twenty students. To assess the reliability of this checklist, at least two professors evaluated each student, and weighted-κ was calculated. Minor revisions were made based on the received feedback. Results: According to our data, the total validity of the tool (S-CVI) was 100%. For all items except one, the weighted-κ coefficient was ≥ 0.5, indicating sufficient reliability for these items. Conclusion: Despite the limitations of the present study, the designed tool to evaluate professionalism among dental students in different clinical departments seems to be both valid and reliable.

A cross-sectional study on COVID-19-related changes in self-medication with antibiotics.

BACKGROUND AND AIM: Dental treatments have been limited to emergency care in many countries worldwide due to the global rapid spread of coronavirus disease-2019 (COVID-19). Fear of contracting the disease in dental clinics has also altered the pattern of dental visits and self-medication. The present study compared self-medication with antibiotics (SMA) and the pattern of dental visits before and after the emergence of COVID-19 pandemic in a referral dental clinic in the north of Iran. MATERIALS AND METHODS: The data for the present cross-sectional study was collected from 756 patient records retrieved from the archives of the Faculty Clinic of Rasht School of Dentistry during two separate periods: before the COVID-19 pandemic from mid-November 2019 to mid-February 2020, and after the pandemic emergence from mid-April to mid-July 2020. In addition to demographic variables namely age, gender, and place of residence of patients, their smoking status, chief complaint, and SMA were also extracted from patient records. The Chi-square test and binary logistic regression models with 95% confidence interval served for statistical analysis. RESULTS: In total, 756 patient records (412 records from the pre-pandemic period and 344 records from the post-pandemic period) were evaluated. SMA was significantly more prevalent after the pandemic compared to that before pandemic (OR = 3.39, 95% CI = 2.43-4.73, P<0.001). The number of patients who smoke significantly decreased after the pandemic by 6.6% compared to that in pre-pandemic period. Dental pain, pus discharge, and abscess as the chief complaints of patients were significantly more prevalent during the post-pandemic period; while, dental checkups, tooth hypersensitivity, and esthetic dental problems were significantly more frequent as the chief complaints of patients during the pre-pandemic period. CONCLUSION: There is indication that during the COVID-19 pandemic, SMA and prevalence of acute dental problems in patients have increased. With regard to the consequences of SMA, there is a need to raise public awareness on this matter.

The Evaluation of the Relationship Between Oral Habits Prevalence and COVID-19 Pandemic in Adults and Adolescents: A Systematic Review.

Background and Objective: The aim of this study was to systematically review the relationship between oral habits (bruxism- temporomandibular disorders) and COVID-19 pandemic in adults and adolescents. Method and Material: A comprehensive search of the literature through PubMed, Scopus, Embase, google scholar and Cochrane databases was conducted. Such keywords as COVID-19, SARS-CoV-2, bruxism, adult, and adolescent were used. Results: In the initial search 818 articles were obtained; 68 cases were duplicates and excluded. By reviewing the article title, 714 articles were removed because they were not relevant to the topic. The remaining articles were reviewed, and studies that did not meet the inclusion criteria, as well as letter to editors and expert opinions were excluded. Finally, 11 articles were allowed to enter the study. Out of 11 related articles, 5 studies were excluded from the present study due to mismatch of the target population; and finally 6 articles were thoroughly reviewed. Conclusion: Studies have shown that stress caused by the COVID-19 pandemic increases detrimental oral habits such as bruxism as well as temporomandibular disorders in adults and adolescents; In general, young single women are at high risk and more exposed to these harmful oral habits.

COVID-19 vaccination and psychological status of Iranian dental students.

Objective: The purpose of the present study was to investigate the association of COVID-19 vaccination with the quality and quantity of sleep, the level of stress, and temporomandibular joint (TMJ) disorders (TMDs) in Iranian dental students. Materials and methods: In this cross-sectional research, we applied a questionnaire including 30 questions on the Perceived Stress Scale (PSS), sleep quality and quantity, Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), and vaccination status. All vaccinated students of the dental schools located in the city of Tehran were invited to participate in the study. Participants were divided into three groups: those vaccinated for less than a month, those vaccinated for 1-3 months, and those vaccinated for more than 3 months. A paired t-test served for statistical analysis. Results: Overall, 171 out of 235 students (72.77%) completed the questionnaire, among which 90 individuals were fully vaccinated, and were included in the data analysis. Stress levels decreased (mean difference = -1.23, p-value = 0.002) and sleep quality and quantity improved mostly 1-3 months after the vaccination (mean difference = -0.5, p-value = 0.016). However, TMD symptoms were mostly alleviated in people vaccinated for more than 3 months (mean difference = -2.86, p-value <0.05). In this respect, no significant difference was observed between the two genders. Conclusion: According to the results of the study, vaccination was associated with the improvement of psychological consequences of the COVID-19 pandemic. It is recommended that further longitudinal studies be conducted on larger sample sizes and different age groups by using various data collection methods (especially regarding the assessment of TMD).

Effectiveness of two interactive educational methods to teach tobacco cessation counseling for senior dental students.

OBJECTIVE: Nowadays, one of the major health problems in many countries is tobacco use. Dental professionals are in a unique position to promote smoking cessation since they have the opportunity for regular interaction with their patients. The purpose of the present study was to compare the effectiveness of two educational methods to teach tobacco cessation counseling (TCC) in dental practice for senior dental students. MATERIALS AND METHODS: In this interventional study, 93 eligible senior dental students from two dental schools in Tehran, Iran were randomly divided into two groups. Two educational programs, role play (RP) and problem-based learning (PBL), with the same aim about TCC in dental practice, were developed and implemented for the two groups. The score of knowledge, attitude, and skill were determined in both groups before and after participation in the course using a questionnaire. The changes in the scores from pre- to post-test were statistically analyzed using repeated measure ANOVA test. RESULTS: Total scores of knowledge, attitude, and skill of the participants showed improvements when compared to scores before training (P < 0.001, P = 0.003, and P < 0.001, respectively). However, the differences between the two study methods were statistically insignificant (P > 0.05). CONCLUSION: The results suggested that TCC training through RP and PBL methods leads to improvement in knowledge, attitude, and skills of dental students in the short-term evaluation.
