Academic stress negatively affects students' performance. However, little is known of the processes that may be involved in this association. This study aimed to analyze how other variables such as coping strategies and exam-related self-efficacy could be related to academic stress and performance for dental students. An online survey, including measures of coping strategies, perceived stress, exam-related self-efficacy, and academic performance, was completed by undergraduate dental students in Madrid, Spain. Of the 275 students invited to take the survey, 201 participated (response rate 73.6%). Rational coping strategies (problem-solving, positive reappraisal, seeking social support) were negatively associated with perceived stress (β=-0.25, p<0.01), whereas emotional coping strategies (venting negative emotions, negative auto-focus) were linked to increased academic stress (β=0.34, p<0.01). Moreover, rational and emotional coping strategies were, respectively, positively (β=0.16, p<0.05) and negatively (β=-0.22, p<0.01) associated with students' exam-related self-efficacy, and this relation was found to be partially mediated by the students' perceived stress (β=-0.30, p<0.01). Experiencing higher levels of stress during the examination period was found to be associated with poorer average grades (β=-0.21, p<0.01), but students' exam-related self-efficacy partially mediated this relation (β=0.23, p<0.01). Those students who perceived themselves as more efficient in completing examinations reported better grades. Using adequate coping strategies (i.e., rational coping) may help to reduce stress for dental students and, through their effect on exam-related self-efficacy appraisals, contribute to improved academic performance.Dr. Crego is Associate Professor,

Introduction The objective of this research is to describe how perceived infectability, germ aversion, and fear of COVID-19 in adults in Madrid have changed from the beginning of the pandemic until the lockdown exit phase and their influence on dental care behaviour. Materials and Methods Some 961 participants were monitored in a study in Madrid at 2 time points: before lockdown (T0) and after completion of the total lockdown (T1). A questionnaire that included basic sociodemographic variables, the perceived vulnerability to disease scale (including perceived infectability and germ aversion), the fear of COVID-19 scale, and dental visiting behaviour after confinement for fear of COVID was administered. Results The participants had higher scores for infectability and germ aversion at T1 than at T0 ( P < 0.01). Of those studied, 24.5% (235) of the participants would not go to the dentist for fear of COVID-19. Those who had a high perceived infectability scale score were at least 5 times more likely to not visit the dentist. Those with high COVID-19 fear were at least 6 times more likely to not visit the dentist, and those older than 60 years were 8 times more likely to not visit. Conclusions The population's high levels of vulnerability to infectability and perceived germ aversion associated with fear of COVID-19 and the resultant avoidance behaviour to dental care will remain until an effective drug or vaccine for SARS-CoV2 is found.

Dental fear is a widely experienced problem. Through a “vicious cycle dynamic,” fear of dental treatment, lower use of dental services, and oral health diseases reinforce each other. Research on the antecedents of dental anxiety could help to break this cycle, providing useful knowledge to design effective community programs aimed at preventing dental fear and its oral health-related consequences. In this regard, frameworks that analyze the interplay between cognitive and psychosocial determinants of fear, such as the Cognitive Vulnerability Model, are promising. The onset of dental fear often occurs in childhood, so focusing on the child population could greatly contribute to understanding dental fear mechanisms and prevent this problem extending into adulthood. Not only can public mental health contribute to population health, but also community dentistry programs can help to prevent dental fear. Regular dental visits seem to act in a prophylactic way, with dental professionals playing an important role in the regulation of the patients’ anxiety-related responses. Both public mental health and community dentistry could therefore benefit from a multidisciplinary approach to dental fear and oral health.

SARS-CoV-2 is a new virus responsible for the outbreak of the respiratory disease COVID-19, which has spread to several countries around the world, causing considerable consternation and a fear of contagions in global healthcare settings. The objective of this study is to identify, among Madrid's adult population, the impact of COVID-19 on self-perceived vulnerability, infectiousness, aversion to germs, and other behaviors in the current situation regarding dental practice. This cross-sectional observational study involves 1,008 persons randomly surveyed on the streets of Madrid, Spain between March 1 and March 8, 2020. Their perceived vulnerability to disease was measured using the perceived vulnerability to disease scale. An additional questionnaire evaluated basic sociodemographic aspects, medical history, personal hygiene behavior, willingness to go to certain places and the perception of the risk of contagion when going to a dental practice. There are significant differences by sex on the germ aversion subscale (p < 0.05) and in the risk of waiting in the waiting room (p < 0.01), tooth extraction ((p < 0.05), endodontics (p < 0.05) and fillings ((p < 0.05). Women consider the risk to be higher than men do. The risk group (over 60 and with systemic disease) has significant differences on the subscales of infectivity (p < 0.01) and germ aversion (p < 0.01). Our study shows high levels of vulnerability regarding contracting COVID-19 and avoiding dental care as perceived by the population over 60 years old and with a systemic disease.

Cognitive elements play a key role in dental anxiety. Nevertheless, relatively little is known about how dental treatments and frequency of visits to the dentist are related to dental fear and its cognitive antecedents. This study aimed to explore the relationships between dental visits, past treatment experiences, expectations on the aversiveness/probability of negative dental events, and dental fear in children. The participants were 147 children (60% female; mean age = 12.0 yr) who completed a questionnaire comprising measures of dental treatment-related experience (attendance, fillings, and extractions), perceived aversiveness and probability of dental events, and dental anxiety. Bivariate correlations and multiple linear regression analyses were used to analyze the data. A higher frequency of dental visits was associated with less dental fear and a decreased belief in the probability of negative events occurring during treatment. The type of treatments received was not directly linked to dental fear. However, having received fillings was significantly associated with the perceived probability of negative dental events, whereas extractions were positively associated with these expectations but negatively associated with the perceived aversiveness of possible dental events. Regular dental visits, as well as dental treatments, can influence, in different ways, cognitive elements associated with dental anxiety in children.
