To examine possible associations between self-reported bruxism, stress, desirability of control, dental anxiety and gagging. Five questionnaires were distributed among a general adult population (402 respondents): the Perceived Stress Scale (PSS), Desirability of Control Scale (DC), Dental Anxiety Scale (DAS), Gagging Assessment Scale (GAS), and Bruxism Assessment Questionnaire. A high positive correlation between DAS and GAS (R = 0·604, P < 0·001) was found. PSS was negatively correlated with DC (R = -0·292, P < 0·001), and was positively correlated with GAS (R = 0·217, P < 0·001) and DAS (R = 0·214, P < 0·001). Respondents who reported bruxing while awake or asleep showed higher levels of GAS, DAS and PSS than those who did not. There were no differences between the bruxers and the non-bruxers (sleep and aware) with regard to the DC scores. The best predictors of awake bruxism were sleep bruxism (OR = 4·98, CI 95% 2·54-9·74) and GAS (OR = 1·10, CI 95% 1·04-1·17). The best predictors of sleep bruxism were awake bruxism (OR = 5·0, CI 95% 2·56-9·78) and GAS (OR = 1·19; CI 95% 1·11-1·27). Self-reported sleep bruxism significantly increases the odds for awake bruxism and vice versa. Tendency for gagging during dental care slightly increases the odds of both types of self-reported bruxism, but desirability of control is not associated with these phenomena.
Background: In late December 2019, a new pandemic caused by the SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) infection began to spread around the world. The new situation gave rise to severe health threats, economic uncertainty, and social isolation, causing potential deleterious effects on people’s physical and mental health. These effects are capable of influencing oral and maxillofacial conditions, such as temporomandibular disorders (TMD) and bruxism, which could further aggravate the orofacial pain. Two concomitant studies aimed to evaluate the effect of the current pandemic on the possible prevalence and worsening of TMD and bruxism symptoms among subjects selected from two culturally different countries: Israel and Poland. Materials and Methods: Studies were conducted as cross-sectional online surveys using similar anonymous questionnaires during the lockdown practiced in both countries. The authors obtained 700 complete responses from Israel and 1092 from Poland. In the first step, data concerning TMDs and bruxism were compared between the two countries. In the second step, univariate analyses (Chi2) were performed to investigate the effects of anxiety, depression, and personal concerns of the Coronavirus pandemic, on the symptoms of TMD, and bruxism symptoms and their possible aggravation. Finally, multivariate analyses (logistic regression models) were carried out to identify the study variables that had a predictive value on TMD, bruxism, and symptom aggravation in the two countries. Results: The results showed that the Coronavirus pandemic has caused significant adverse effects on the psychoemotional status of both Israeli and Polish populations, resulting in the intensification of their bruxism and TMD symptoms. Conclusions: The aggravation of the psychoemotional status caused by the Coronavirus pandemic can result in bruxism and TMD symptoms intensification and thus lead to increased orofacial pain.
The origins of dental fear and anxiety are numerous and complex. The purpose of the present study was to evaluate the relative effects of learned responses and subjective personality traits on the development of dental anxiety. The study was carried out in kibbutzim (closed homogeneous societies) in Israel where all subjects had received dental treatment from the same dentist since childhood with no choice of dentist. Subjects were requested to fill out questionnaires concerning their dental anxiety (DAS) in the past and at present, an evaluation of their dentist in the past and at present, and a psychopathologic symptom survey (SCL-90). The results show that dental anxiety at present correlates significantly with the evaluation of the present dentist; with dental anxiety as remembered from childhood; and with the following SCL-90 scales: interpersonal sensitivity, anxiety, phobic anxiety and Positive Symptom Distress Index. The best predictors of dental anxiety at present were the evaluation of the present dentist and past dental anxiety (as remembered from childhood). The results suggest that the level of the subject's dental anxiety is affected by environmental factors (evaluation of the present dentist, memories of anxiety from childhood), and by personality traits as evaluated by the SCL-90 questionnaire.
Aim Dentistry is a stressful and exhausting profession with high levels of burnout. Sensory processing sensitivity (SPS) is a basic personality trait characterised by a gradient of sensitivity to both internal and external stimuli, including social and emotional cues. In this study, the influence of SPS on burnout and professional quality of life among Israeli dentists was analysed. Methods Two‐hundred and forty‐three Israeli dentists responded to questionnaires that collected information on their SPS and professional quality of life (burnout, satisfaction at work and level of secondary traumatic stress), as well demographic variables, professional specialisation and workload. Results Linear regression analyses showed that burnout can be predicted by the three aspects of SPS (ease of excitation, low sensory threshold and aesthetic sensitivity; 32% of the variance). Additionally, the same three aspects of SPS also predicted dentists’ satisfaction at work (24% of the variance). Ease of excitation and low sensory threshold, but not aesthetic sensitivity, predicted dentists’ reaction to their patients’ stress and trauma (23% of the variance). Conclusions Sensory processing sensitivity can serve as a tool to identify dentists who are prone to develop burnout and whose professional quality of life can be adversely affected by their profession.
