The novel coronavirus disease COVID-19 was first detected in Wuhan, the capital of Hubei province, China, in December 2019, and it was announced that COVID-19 has become an important public health problem at the international level by the World Health Organization [1-3]. As in the world, serious measures have been taken in Turkey due to high-risk of being infected with this disease. Travel restrictions, quarantine applications, providing social isolation, and closing social areas, such as sports halls, museums, movie theaters, swimming pools, restaurants, and hairdressers, can be counted among these measures [4]. In addition to these precautions, it was recommended that all educational institutions switch to online education [5]. In this respect, face-to-face education of dentistry faculties were interrupted, especially due to the education procedures involving the possibility of close contact with symptomatic and asymptomatic COVID-19 patients and the application of aerosol-producing treatment [4, 6]. It has been announced that teaching at universities in Turkey was suspended two days after the first case of COVID-19 was detected on March 11, 2020. Online theoretic education has started at our university on March 23, 2020 [5]. During the COVID-19 pandemic, online education systems provided advantages such as continuity of edu-cation, problem-based learning, and the use of intelligent communication devices and applications; therefore, the students had the opportunity to learn anywhere and anytime. However, from time to time, problems related to universities’ digital platforms and interruptions in students’ internet access were encountered [7]. At time, the study examining the psychological effects of academic disruptions on students were carried on, it was observed that students’ anxiety tendency may have increased, especially due to the interruption of education, which has decreased the motivation about studying. Also, there was a significant potential increase of students’ dropout due to the abandonment of daily routines [3, 8-11]. In addition to all these negative factors, it was assumed that the increase of anxiety resulting from the provision of individual safety and preventing the risk of contamination could have negative effects on psychological health of dentistry students [4, 11, 12]. For the duration of the pandemic, it is particularly important to determine and implement without a delay, all the necessary measures to protect mental health and well-being of dentistry students. It is also important to determine the need for professionally trained counselors, who can understand the psychological status of students [11, 12]. Until today, numerous scales such as the dental environment stress (DES), Beck depression inventory (BDI), and state-trait anxiety inventory (STAI) have been used to determine the current psychological state [13]. STAI is an important index in determining how the individual feels at a certain moment and under specific conditions (STAI-1), and independently of the situation and conditions (STAI-2) [14]. Also, it offers a more comprehensive assessment due to its content [13, 14].


Although a few studies [15, 16] were performed on medical students regarding COVID-19 stress levels, to the best of our knowledge, no study identifying the stress of dental students during COVID-19 or other pandemic periods was published. The aim of the study was to evaluate the views and anxiety levels of dentistry students during the COVID-19 pandemic.


This study was approved by the Ministry of Health, Republic of Turkey (No: 2020-05-20T15_30_12). Ethical approval was received from the Ethics Committee of Pamukkale University (No: 60116787-020/31819).


The survey was completed by the students of the Pamukkale University, Faculty of Dentistry (Denizli, Turkey). Participation in the survey was voluntary. Demographic information was collected, including age, gender, and year of study. The survey was completed by preclinical (first and second years of study) and clinical years (third and fourth years of study) dental students. Participants who used psychiatric medication in the past year were excluded from the study. In Turkey, dental education continues for five years. Our faculty began teaching in 2016 in Denizli, Turkey. The current study was carried out among our students studying in the first four years of study, as there are currently no fifth-year students. For this reason, our study was conducted only with the participation of students up to the fourth-year.


The survey was prepared on an online survey portal (www.surveey.com) and the link was sent to the dental students via smart-phones. An informative text was provided before starting the survey. Only students who voluntarily agreed to participate in the study filled up the survey. The whole survey included two main parts. The questions in the first part were about the views of dental students regarding COVID-19 and tele-education (Table 1). For the second part, STAI scales were used. This inventory was developed by Spielberger et al. [14], with an adaptation of Turkish validity and reliability study performed by Oner and Le Compte [17] consisted of two sub-scales, with each containing 20 questions. The scores obtained from both scales ranged from 20 to 80. A high score was associated with high anxiety level, while a low score related to low anxiety. The average score level determined in the studies varies between 36 and 41 [18]. All participants completed both general questions and Turkish versions of STAI-1 and STAI-2 scales. The data obtained from the surveys was collected, and statistical analysis was performed.


Three hundred and sixty students of the Pamukkale University Faculty of Dentistry constituted of the research. For the 95% confidence interval (t: 1.96), when the frequency of view of the examination was taken as 0.05, and the accepted sampling error was 0.05, the number of samples calculated according to the formula below was 186 [19]: n = Nt2pq d2(N – 1) + t2pq NCSS (number cruncher statistical system) 2007 (Kaysville, Utah, USA) program was used for statistical analysis. The data was evaluated by descriptive statistical. The distribution of data was evaluated with Shapiro-Wilk test. ANOVA was used for the comparison of three or more groups with normal distribution of quantitative data, and post-hoc tests were used to determine the differences. Student’s t-test was used to compare two groups with normal distribution of quantitative data. Statistical significance was estimated at p < 0.01 and p < 0.05.


A total of 249 dental students (154 females, 95 males), including 143 preclinical (first and second year of study) and 106 clinical students (third and fourth-year of study) participated in the survey (Table 1). The response rate was 69.2%. Percentages of participation were 29.1%, 28.7%, 21.5%, 20.7% for first and fourth-year of study, respectively. The age range of the participants ranged from 18 to 24, with a mean of 20.7 ± 1.4. The majority of the participants did not have a chronic disease and followed the news about COVID-19. Most of respondents stated that they prefer online education. One-third of the participants indicated that they plan to stay alone at the student house after the COVID-19 period. The vast majority of the students confirmed that they are concerned about the classes held in groups, with the transition to face-to-face education. Details are shown in Table 1. With the normalization of the COVID-19, 83.9% (n = 209) of the participants indicated that they consider the dining halls risky after the pandemic, 13.7% (n = 34) were not sure about this issue, and 2.4% of them (n = 6) did not find it risky. Most of the participants would prefer to use personal protective equipment in classes (Table 1). On a question regarding the type of protective measures during the lessons, 41.4% (n = 103) of the students responded that they would use masks, shields, and gloves, 38.6% (n = 96) would use masks, visors, gloves, and disposable gowns, 14.5% (n = 36) would use masks only, 4.4% (n = 11) would use masks and shields, and 1.2% (n = 3) would use shields only. Most of the participants (69.9%) stated that the idea of late graduation created anxiety. Due to the COVID-19 pandemic, it is noteworthy that approximately a quarter of the students had the idea of changing the profession (Table 1). Table 1 presents the comparison of the variables and STAI scales. When comparing the variables according to STAI-1, the average of the scale with any variable was not statistically significant (p > 0.05). On the other hand, according to the STAI-2 scale, the mean of the scale showed a statistically significant difference only in the variable, in which the idea of changing the profession was indicated (p = 0.031, p < 0.05). The continuity anxiety value of the group with the idea of changing the profession was higher than the group that have not thought of changing the profession (p = 0.026, p < 0.05).


Dentistry is considered an extremely stressful profession. Education life is also demanding, as it is a period that requires intensive theoretical knowledge along with interpersonal communication skills and clinical abilities [20, 21]. In previous studies, it has been reported that the stress in dentistry students varied according to ethnic differences, gender, and year of study [13]. The COVID-19 pandemic has been affecting lives of many people worldwide. The rapid increase in the number of infected cases preceded to increased feelings of uncertainty and anxiety in humans. Disruption in education and other issues also caused anxiety among university students [15]. Increased stress level in students can lead to lack of concentration and deterioration of their psychological states [8]. Students returning to their homes because of the closure of the universities are worried about not being able to return to their schools. The measures taken by universities to support the mental state of students are uncertain [8]. Our study aimed to evaluate the current psychological states of dental students during the COVID-19 period. Stress levels of dental students were evaluated by using various scales, including STAI, DES, BDI, depression, anxiety and stress scale (DASS), Maslach burnout inventory (MBI), psychosocial stress inventory (PSSI), brief symptom inventory (BSI), generalized anxiety disorder (GAD), and psychological general well-being (PGWB) [13, 22-26]. STAI-1 scale aims to determine the persistent anxiety of a person, while STAI-2 aims to assess the continuity of anxiety [13]. In the current study, we preferred STAI scales because they allow both a certain time and a long time to be evaluated and are more appropriate for periods with psychological variations, such as pandemics. In the literature, there are studies, in which stress levels of medical students are measured after pandemics that have appeared before [26, 27]. Loh et al. [27] evaluated the knowledge and anxiety of medical students during severe acute respiratory syndrome (SARS) outbreak in 2003. The researchers reported that junior medical students expressed higher anxiety levels, compared to senior medical students [27]. In our COVID-19 study, no statistical differences were found between the education level and anxiety. Al-Rabiaah et al. [26] investigated the stresses of medical students in the Middle East during respiratory syndrome-related coronavirus (MERS-CoV) outbreak, which occurred in 2014. According to that study, about a quarter of medical students have been reported to be affected by mild to moderate anxiety [26]. Moreover, the researchers found that females students had statistically higher stress levels than males; however, no differences were observed between education levels. The only study evaluating the anxiety levels of medical students in the COVID-19 pandemic was performed by Cao et al. [16]. In this study, 21.3% of the medical students presented mild, 2.7% of them showed moderate, and 0.9% of them had severe anxiety levels. Similar to previous studies, it was determined that the students in our study were anxious about pandemic [15, 16, 26]. On the other hand, there was no statistical difference between gender and anxiety levels in our study, which corresponded to results of Cao et al. [16] but contrasted with the study of Al-Rabiaah et al. [26]. The only study evaluating the views of medical students during COVID-19 outbreak was performed by Aker and Midik [15]. In this study, serious issues regarding COVID-19 pandemic, in which medical students were most interested were investigated, and the question of “how/when the pandemic will come to end” was at the top of the most interested topics (42.9%). The effect of COVID-19 on education was the most concerned subject for only 4.5% of students. Furthermore, more than half of the participants indicated that they were mentally poor [15]. In our study, dental students’ anxiety levels were questioned and their anxiety in education-related issues was found to be high. The high level of anxiety in dental students was thought to be associated with the high-risk of cross-contamination caused by aerosols during dental procedures and close contact with patients [4, 6]. In our study, the results of students preferring online education rather than face-to-face education, and that most of them will pay attention to personal protective measures, support this situation. Additionally, it was determined that a group of dental students considered changing their professions because of high-risk of infection in dental procedures, and their continuity anxiety levels (STAI-2) were higher than other students (p < 0.05). Among the limitations of our study, as in other cross-sectional studies, our results demonstrate a certain period of the pandemic. Moreover, as this study includes students from one dental faculty, these results may vary in other faculties and/or other countries. New studies are recommended at different phases of pandemics, in different countries, and with bigger number of participants.


The results of our study indicated that dental students were anxious about the COVID-19 pandemic. The severity of the mental health of dentistry students should be determined with detailed analysis. It should be emphasized that universities should establish crisis-oriented psychological support programs for dentistry students during a pandemic and cooperate with other public institutions in this sense. Dentistry faculties need to reconsider training and infection protocols, so that students can spend this period during the unexpected pandemic without interrupting their education and suffering psychological concern.
