Temporomandibular disorders and bruxism - up-to-date assessment and screening tools the general dentist should be aware of.

The recently proposed shortened screening tools for temporomandibular disorders (TMD) and bruxism should enable a better assessment of these conditions by the general dentist.

Excessive Gag Reflex, Dental Anxiety, and Phobia of Vomiting in Dental Care.

BACKGROUND: The most known and commonly studied behavioral obstacle to dental care is dental anxiety. An obstacle that is less studied though no less problematic is excessive gag reflex, which can severely impede dental treatment. Another understudied and possibly related syndrome is emetophobia (a specific phobia of vomiting). OBJECTIVE: The aim of this study was to examine possible comorbidity amongst self-reported emetophobia, dental anxiety, and excessive gagging in the dental office. METHODS: A cross-sectional online survey was conducted using the following self-report questionnaires: Dental Anxiety Scale, Gagging Problem Assessment, Gagging Assessment Scale (GAS), and Specific Phobia of Vomiting Inventory (SPOVI). RESULTS: In all, 164 participants fully completed the questionnaires (87.8% female; mean age, 34 ± 11.07 years). Positive correlations were found amongst all variables (P < .001). High gagging (GAS > 6) was associated with a 7.29 times (P < .000) greater risk of positive emetophobia (SPOVI ≥ 10). Linear regression analyses revealed that the intensity of the reflex and the experience of gagging upon encountering odours in the dental office as well as dental anxiety and vomiting phobia significantly predicted participants' gagging scores as evaluated by GAS (R2 = 0.59; F = 21.16; P < .001). CONCLUSIONS: The study shows that excessive gagging reflex in the dental office is closely related both to dental anxiety and to emetophobia.

The continuous adverse impact of COVID-19 on temporomandibular disorders and bruxism: comparison of pre- during- and post-pandemic time periods.

INTRODUCTION: Some of the conditions affected by the COVID-19 pandemic were Temporomandibular Disorders (TMD) and bruxism. The present study compares the effect of the pandemic on TMD and bruxism (sleep and awake) in three time periods: before the pandemic (pre-COV), during the pandemic (during-COV) and after the pandemic subsided (post-COVR). MATERIAL AND METHODS: A total of 587 adult patients (108 in the pre-COV group, 180 in the during-COV group and 252 in the post-COVR group) who arrived for a routine dental treatment between October 2018 and January 2023 were evaluated according to Axis I diagnosis of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Each patient received a DC/TMD Axis I diagnosis as follows: (i) Painful TMD (defined by the presence of at least one of the following - local myalgia, myofascial pain with referral, arthralgia or headache attributed to TMD); (ii) Non painful TMD (defined by the presence of disc displacement with/without reduction, degenerative joint disorders and/or dislocation), (iii) Possible sleep bruxism (SB) and/or (iv) Possible awake bruxism (AB). STATISTICAL METHODS: Logistic regression analyses were conducted to establish the impact of time and gender on the prospects of painful TMD, non-painful TMD, SB and AB. RESULTS: The odds of subjects to be diagnosed with painful TMD at the post-COVR era were 3.3 times higher compared to the pre-pandemic time period (pre-COV, 95% C.I. 1.438-7.585). The odds of subjects to be diagnosed with non-painful TMD during-COV were 4 times higher compared to the pre-COV era (95% C.I. 1.332-12.542). The odds of subjects to present possible SB at post-COVR were 2.7 times higher compared to pre-pandemic (pre-COV, 95% C.I. 1.258-5.889, p < 0.05) and the odds to present possible AB after the pandemic subsided (post-COVR) were 3.2 times compared to the pre-pandemic period (95% C.I. 1.496-6.949). The odds of female subjects to be diagnosed with either painful or non-painful TMD were 3.7-4.4 times higher, compared to males. CONCLUSIONS: Results indicate that with regard to TMD and bruxism the pandemic adverse effects persist also after COVID-19 subsides and the restrictions caused by it are abolished. Apparently, during the pandemic females were affected more seriously by painful and non-painful TMD than males.

Sleep Bruxism in Children-What Can Be Learned from Anamnestic Information.

Sleep bruxism (SB) is a masticatory muscle activity during sleep, and its clinical manifestation in young children is still unclear. The aim of the present study was to evaluate the role of anamnestic information in predicting possible SB in children aged 4-12 years. In a cross-sectional retrospective exploratory study, the dental files of 521 children were examined with regard to the following anamnestic information: gender, age, medical conditions associated with ear, nose, and throat (ENT), respiratory disorders, use of methylphenidate (Ritalin), oral habits, and bruxing during sleep. A child was defined as presenting possible SB when a positive report was received from parents regarding such behavior (SB positive, No. = 84). There were no age- and/or gender-wise differences between SB-positive children and children whose parents did not report SB behavior (SB negative). SB-positive children suffered more from ENT and respiratory disorders than children without SB. Additionally, the use of pacifiers/finger sucking, as well as snoring, were more common among SB-positive children as compared to their SB-negative counterparts (Chi-square). The variables which were found to significantly increase the odds of possible SB in children were mouth breathing, ENT problems, and use of a pacifier or finger sucking (forward stepwise logistic regression). Clinicians should look for clinical signs of possible SB in children whose anamnesis reveals one or more of these anamnestic signals.

The Influence of Family Milieu on Dental Anxiety in Adolescents-A Cross-Sectional Study.

Parents play a significant role in the development of dental anxiety in their adolescent children. This cross-sectional study aimed to evaluate the influence of family milieu on adolescents' dental anxiety. The level of dental anxiety (Dental Anxiety Scale-DAS) was evaluated in 100 adolescent dental patients (ages 13-18 years) and their parents. Parents supplied information about family demographics and their personal experiences of dental treatment. Concomitantly, the family's behavior was observed during the dental encounter. The adolescents' mean DAS score was 9.83 ± 2.05. Adolescents' DAS was higher when their parents' memories from their own dental encounters were negative. A positive correlation was found between adolescents' dental anxiety and that of their father (r = 0.52, p < 0.001) and mother (r = 0.79, p < 0.001). The following variables showed a significant ability to predict adolescents' dental anxiety (stepwise regression): mother's DAS (B = 0.57), adolescent's behavior at the dental visit (B = 0.87), being the firstborn child (B = -0.44), father's DAS (B = 0.13), and mother's level of education (B = -0.10). The results showed that intra-family relationships and behavior, parents' education, dental fear, and memories from previous treatments play an important role in defining the level of dental anxiety in their adolescent children.

Fluorescent Marker as a Tool to Improve Strategies to Control Contaminated Surfaces and Decrease Danger of Cross-Contamination in Dental Clinics, during and beyond the COVID-19 Pandemic.

The COVID-19 pandemic posed an increased threat to dental personnel and patients. Close encounters with patients' breath and saliva and the use of intraoral rotating instruments which disperse microscopic airborne particles both increase the possibility of environmental infection. In this study, fluorescent marker (FM) was used to assess and enhance surface cleanliness in the dental clinics and public areas of a major dental school. Initially, 574 surfaces in various areas of a dental school were marked with FM for 3 consecutive months to monitor the surface cleanliness. The initial evaluation results were visually presented to both students and para-dental and cleaning personnel during a designated educational session, and were used to stress the importance of preventing cross-contamination. Following educational intervention, 662 surfaces were re-examined for an additional 3 months, using the same method. A significant improvement in the surfaces' cleanliness (ANOVA, F(1) = 10.89, p < 0.005) was observed post-intervention. The results were more prominent in students' clinics, which were the students' cleaning responsibility. The results show that fluorescent markers can serve as an educational tool to improve strategies to control contaminated surfaces in large clinics, such as dental schools. Their use can substantially decrease the hazard of cross-contamination during the pandemic and beyond.

Temporomandibular Disorders and Bruxism among Sex Workers-A Cross Sectional Study.

Sex workers are a highly underprivileged population which is present all around the world. Sex work is associated with negative social stigma which affects all aspects of the sex workers' lives including healthcare, service providers and police. The stigma may result in increased stress, mental health problems, feelings of isolation and social exclusion. In the present study, 36 sex workers (SW) and 304 subjects from the general population in Israel (GP) were evaluated for the presence of bruxism and Temporomandibular disorders (TMD), with the use of Diagnostic Criteria for Temporomandibular Disorders (DC/TMD- Axis I). When compared to the general population, sex workers presented larger maximal assisted mouth opening and higher prevalence of the following TMD diagnoses: Disc displacement with reduction, Myalgia, Myofascial pain with referral, Arthralgia (left and right) and Headache attributed to TMD. The odds of sex workers suffering from one of these diagnoses were twice to five times higher than those of the general population. The study shows that health problems of sex workers go beyond venereal diseases, HIV and mental disorders which are commonly studied. Oral health, TMD and oral parafunctions are some of the additional health issues that should be addressed and explored in this population.

Sleep-Related Breathing Disorders in Children-Red Flags in Pediatric Care.

OBJECTIVES: In recent years, we have witnessed a growing interest in pediatric sleep-related breathing disorders (SRBD). Although a Pediatric Sleep Questionnaire (PSQ) exists and was found reliable in screening SRBD in children, many of the children remain underdiagnosed. The aim of the present study was to define anamnestic and clinical findings that can serve as red flags indicating the presence of SRBD in children. METHODS: 227 children aged 4-12 years old were evaluated with regard to the following parameters: (i) anamnestic variables (e.g., general state of health, oral habits, bruxism, esophageal reflux, sleep continuity, snoring); (ii) clinical parameters (e.g., oral mucosa, palate, tonsils, tongue, floor of the mouth, angle classification, gingival health, caries risk) and (iii) presence of SRBD (through the PSQ). RESULTS: Significant differences between children with and without SRBD were observed regarding continuous sleep, developmental delay, mouth breathing, and snoring. Taking medications for ADHD increased the odds of SRBD in children by over seven times, non-continuous sleep increased the odds of SRBD by six times, mouth breathing increased the odds by almost five times, and snoring increased the odds by over three times. CONCLUSIONS: Child caregivers from various fields (dentists, orthodontists, pediatric physicians, school nurses) should actively inquire about disturbed sleep, medications for ADHD, snoring, and mouth breathing among their young patients. Initial screening through a few simple questions may help raise red flags that can assist in the early detection of SRBD in children and lead to proper diagnosis and treatment.

Can Intra-Oral Qualitative Sensory Testing Foretell Postoperative Dental Pain? A Preliminary Report.

Pain prevention and management is one of the primary goals of dental care. Postoperative dental pain (PDP) following caries removal and performance of a restorative dental treatment is a common clinical phenomenon, often causing significant discomfort to dental patients. In the present study, a psychophysical non-invasive method, qualitative sensory testing (QualST), was used in an attempt to foretell PDP following dental restorative procedures. Forty-two dental patients underwent an intra-oral cold QualST four times: immediately prior to a restorative dental procedure and at a follow-up meeting 1−3 weeks later, on the treated and on the contralateral oral sides. The QualST measures included subjects' evaluation of the magnitude of pain and cold sensations experienced (on visual analogue scales) and the duration of the cold sensation (in seconds). Additional measures included age, gender, level of dental anxiety, jaw treated, and type of dental restoration performed (Class I or Class V). Subjects' PDP was assessed through the phone using numeric rating scales 24, 48, and 72 h postoperatively. The highest level of PDP experienced by subjects occurred 24 h postoperatively (ANOVA with repeated measures). Of the study variables, the QualST pain sensation (B = 0.645, p < 0.001), duration of the cold sensation (B = 0.042, p < 0.05), and an interaction between gender and dental anxiety (B = 0.136, p < 0.05) emerged as possible predictors of the highest PDP experienced by subjects (stepwise regression). The results suggest that subjects' reaction to an intra-oral cold stimulation of the oral mucosa can serve as a potential tool to foretell postoperative dental pain following restorative dental procedures.

Symptoms of Nocturnal Masticatory Muscle Activity among Women of Different Age Groups and Their Association to Obstructive Sleep Apnea-A Cross Sectional Study.

Sleep bruxism (SB), snoring, and excessive daytime sleepiness are often associated with obstructive sleep apnea (OSA). OSA, which is characterized by a repetitive collapse of the upper airway during sleep, can cause oxygen desaturation and lead to adverse medical conditions, such as cardiovascular events, hypertension, heart attack, and stroke. In the present study, 112 Arab women aged 20−40 years (Early Adulthood/Adulthood−EarlyA) and 116 Arab women aged 50 and above (Middle Age−MiddleA), were requested to complete questionnaires regarding demographic variables, symptoms of nocturnal masticatory muscle activity (possible SB, headache, and stiffness of the oral and/or neck musculature upon awakening), risk of OSA (STOP-BANG questionnaire), and daytime sleepiness (Epworth sleepiness scale­ESS). Women, who reported snoring, experienced more SB (35.8% vs. 20.6%, chi-square, p < 0.05), more headaches (33.3% vs. 19.3%, p < 0.05), and more muscle stiffness upon awakening (34.3% vs. 16.3%, p < 0.005), than their non-snoring counterparts. Out of the women who snore, 11% showed high risk for OSA, as compared to only 1% among the non-snoring participants (p < 0.000). Symptoms of nocturnal masticatory muscle activity and/or snoring can serve as initial indicators of OSA. Higher awareness of dentists to such symptoms, particularly among their middle-aged female patients, can prevent a development of harmful conditions associated with OSA.

Stress Coping Strategies, Burnout, Secondary Traumatic Stress, and Compassion Satisfaction Amongst Israeli Dentists: A Cross-sectional Study.

OBJECTIVE: Being a member of the dental profession is often associated with stress and high levels of burnout. Stress coping strategies may significantly help mediate burnout. The present cross-sectional study sought to examine the role of stress coping strategies on burnout, secondary traumatic stress, and compassion satisfaction amongst Israeli dentists. METHODS: The study was carried out amongst Israeli dentists with the use of the following questionnaires: (1) the Professional Quality of Life Scale 5 (ProQOL), referring to burnout, compassion satisfaction, and level of secondary traumatic stress; (2) the Coping Inventory for Stressful Situations-Situation Specific Coping Inventory (CISS-SSC), referring to coping strategies (task-focused, emotion-focused, or avoidance-focused coping); and (3) demographic and professional variables (eg, specialisation, workload). Participants included 243 Israeli dentists. Univariate analyses and linear regressions were conducted to evaluate the relationships amongst coping strategies and burnout, secondary traumatic stress, and compassion satisfaction. RESULTS: Female dentists had higher emotion-focused and avoidance coping scores than male dentists. Burnout could be explained by higher emotion-focused coping scores and lower task-focused and avoidance-focused coping. Secondary traumatic stress could be explained by higher emotion-focused scores, having fewer years of professional experience, and younger ages. Compassion satisfaction could be explained by lower emotion-focused coping as well as by higher task-focused coping and workload scores, specialisation, and gender. CONCLUSIONS: The findings suggest that emotional coping may cause dentists to be vulnerable to burnout and to secondary traumatic stress.

Psychosocial and Behavioral Factors in Awake Bruxism-Self-Report versus Ecological Momentary Assessment.

The issue of psychosocial factors and concurrent conditions associated with AB is a relatively new approach in the study of Awake Bruxism (AB). In the present study a population of 84 dental students were assessed for probable AB with two modes of AB assessment: Single point self-report (SR) and ecological momentary assessment through a designated smartphone application (BA). The two assessment modes were compared with regard to their ability to phenotype subjects as far as the following psychosocial and behavioral variables are concerned: Gender; depression; somatization; oral behaviors; chronic pain and associated pain symptoms in the head, neck and scapula. Two-way ANOVA showed main effect of SR for the following variables: Chronic Pain Intensity score (F(1,49) = 6.441, p < 0.02), migraine/headache (F(1,81) = 7.396, p < 0.01), pain in neck (F(1,81) = 6.726, p < 0.05), pain in scapula (F(1,81) = 8.546, p < 0.005) and the oral behaviors of pushing the tongue forcefully against the teeth (F(1,81) = 5.222, p < 0.05) and inserting the tongue between the upper and lower teeth (F(1,81) = 5.344, p < 0.03). The effect of SR on the habit of chewing gum was borderline (F(1,81) = 3.369, p = 0.07). Main effect of BA was found for depression (F(1,81) = 6.049, p < 0.05), while the effect of BA on somatization was borderline (F(1,81) = 3.657, p = 0.059). An interaction between SR and BA groups could be observed for the behavior of biting, chewing or playing with the tongue, cheeks or lips (F(1,81) = 4.117, p < 0.05). The results suggest that a combination of a single-point self-report referring to the past 30 days, and an ecological momentary assessment supplying information about the actual timing of the report, can help us to better assess AB, as well as increase our ability to define the phenotype of subjects with AB as far as psychosocial and behavioral factors are concerned.

One year into the COVID-19 pandemic - temporomandibular disorders and bruxism: What we have learned and what we can do to improve our manner of treatment.

The coronavirus disease 2019 (COVID-19) pandemic has drastically changed the routine way of life and challenged the ways in which health and dental services are provided. During the 1st lockdown, practiced in most of the countries, routine dental procedures were suspended. Even after the lockdown was eased, visiting crowded dental clinics was still considered health-threatening, especially among populations at high risk of developing a severe reaction to COVID-19. Regretfully, in most cases, temporomandibular disorders (TMD) and bruxism were not included under the definition of emergency, leaving many patients without the possibility of consulting their dentists. A literature search, performed about 10 months after the declaration of the pandemic, found only a few studies dealing with TMD and bruxism during COVID-19. Most of the studies indicate adverse effects on subjects' psycho-emotional status (stress, anxiety, depression), which in turn lead to the intensification of subjects' TMD and bruxism symptoms, and increased orofacial pain. Unlike other oral pathologies, which require manual interventions, chronic orofacial pain can be addressed, at least at its initial stage, through teledentistry and/or consultation. Remote first aid for patients suffering from orofacial pain includes various kinds of treatment, such as the self-massage of tense and painful areas, stretching, thermotherapy, drug therapy, relaxation techniques, meditation, and mindfulness, all of which can be administered through the phone and/or the Internet. Relevant legal and ethical issues should be considered while using remote modes for the triage, diagnosis and treatment of chronic orofacial pain patients.

Public Concerns during the COVID-19 Lockdown: A Multicultural Cross-Sectional Study among Internet Survey Respondents in Three Countries.

(1) Background: this study aimed to evaluate the worries, anxiety, and depression in the public during the initial coronavirus disease 2019 (COVID-19) pandemic lockdown in three culturally different groups of internet survey respondents: Middle Eastern (Israel), European (Poland), and North American (Canada). (2) Methods: a cross-sectional online survey was conducted in the mentioned countries during the lockdown periods. The survey included a demographic questionnaire, a questionnaire on personal concerns, and the Patient Health Questionnaire-4 (PHQ-4). A total of 2207 people successfully completed the survey. (3) Results: Polish respondents were the most concerned about being infected. Canadian respondents worried the most about their finances, relations with relatives and friends, and both physical and mental health. Polish respondents worried the least about their physical health, and Israeli respondents worried the least about their mental health and relations with relatives and friends. Canadian respondents obtained the highest score in the PHQ-4, while the scores of Israeli respondents were the lowest. (4) Conclusions: various factors should be considered while formulating appropriate solutions in emergency circumstances such as a pandemic. Understanding these factors will aid in the development of strategies to mitigate the adverse effects of stress, social isolation, and uncertainty on the well-being and mental health of culturally different societies.

Awake Bruxism-Single-Point Self-Report versus Ecological Momentary Assessment.

Assessment of awake bruxism (AB) is problematic due to the inability to use continuous recordings during daytime activities. Recently, a new semi-instrumental approach was suggested, namely, ecological momentary assessment (EMA), via the use of a smartphone application. With the application, subjects are requested to report, at least 12 times per day, the status of their masticatory muscle activity (relaxed muscles, muscle bracing without tooth contact, teeth contact, teeth clenching, or teeth grinding). The aim of the present study was to test the association between a single observation point self-report and EMA assessment of AB. The most frequent condition recorded by the EMA was relaxed muscles (ca. 60%) and the least frequent was teeth grinding (less than 1%). The relaxed muscle condition also showed the lowest coefficient of variance over a seven-day period of report. Additionally, only the relaxed muscles and the muscle bracing conditions presented an acceptable ability to assess AB-positive and AB-negative subjects, as defined by single-point self-report questions. The combination between self-report and EMA may have the potential to promote our ability to assess AB. We suggest to re-consider the conditions of teeth contact and teeth grinding while using EMA to evaluate AB.

The effect of smartphones on daytime sleepiness, temporomandibular disorders, and bruxism among young adults.

OBJECTIVES: Effects of modern cellular technology on our lives is a relatively new topic of interest. The aim of the present study was to investigate the effect of smartphone use on daytime sleepiness, temporomandibular disorders (TMD), and bruxism (sleep and awake) among young adults in Israel. METHOD AND MATERIALS: Questionnaires on demographic variables, mobile phone use characteristics, anxiety, depression, daytime sleepiness, bruxism (sleep and awake), and diagnosis of TMD were filled in by ultra-Orthodox young adults (18 to 35 years of age) using a simple mobile device with no internet connection, religious young adults who use an internet-connected smartphone solely for work purposes, and secular young adults with an internet-connected smartphone for unlimited use. RESULTS: Various aspects of smartphone use, including being awakened at night by the phone, stress caused by information delivered by the phone, and stress from phone overuse increased the risks of daytime sleepiness, TMD, and bruxism. Those sequelae are associated with substantial negative effects on both the individual and society. High risks of motor vehicle accidents, chronic orofacial pain, and irreversible damage to hard dental tissue structures are some of those negative consequences. CONCLUSIONS: The adverse effects of smartphone use on daytime sleepiness, TMD, and bruxism are substantial. Their influence on public health and health care costs are causes of concern.

Dental personnel in Israel, Canada, and France during the COVID-19 pandemic: attitudes, worries, emotional responses, and posttraumatic growth.

OBJECTIVES: The spread of COVID-19 has posed significant challenges for dental professionals worldwide. The aims of the present study were twofold: (i) to study the attitudes, emotional responses, and worries among the dental personnel; and (ii) to look for the ability of dental personnel to experience posttraumatic self-growth as a result of the distress caused by the pandemic. METHOD AND MATERIALS: A cross-sectional online survey using an anonymous questionnaire was performed simultaneously in Israel, Canada, and France during the initial lockdown period. RESULTS: Israeli dental practitioners were less worried about their physical health, mental health, or relationships with family and friends than their Canadian and French counterparts. The Canadian dental practitioners were most committed and most willing to treat their patients, as well as most concerned about not being able to treat patients in the same personal way as before the lockdown. French dental practitioners showed the highest level of fear to treat patients. There were no differences in dental practitioners' levels of anxiety, depression, or posttraumatic growth among the countries. Dental practitioners' posttraumatic growth was significantly associated with worries regarding their physical health. CONCLUSION: Responses of dental personnel to the COVID-19 pandemic varied worldwide. Despite the differences, evidence exists that some of the dental practitioners' worries and concerns are associated with psychologic growth as a result of the pandemic. Better understanding and acknowledgment of dental personnel's worries and concerns can facilitate growth and enable positive functioning under the continuous situation of uncertainty.

The Association between Emotional Stress, Sleep, and Awake Bruxism among Dental Students: A Sex Comparison.

Psychosocial factors may play an important role in the etiology of sleep and awake bruxism. The purpose of this study was to assess the relationship between emotional stress and bruxism in male and female dental students at various stages of their education. Dental education in Israel is based on a six-year curriculum, divided into three stages: pre-medical studies (yr. 1-2), manual skills (yr. 3-4), and clinical experience (yr. 5-6). Each stage requires different capabilities and skills. Questionnaires regarding psychological state (SCL-90) measuring depression, anxiety, and somatization as well as stress evaluation questioners (Perceived Stress Scale questionnaire 14) were completed by 387 dental students in the 1st to 6th years. Sleep and awake bruxism were evaluated based on the respondent's awareness. During the manual stage of studies, a significant increase was identified, albeit with weak correlations, between stress scales, depression, anxiety, somatization, and the prevalence of awake bruxism, particularly among males. Only in females was sleep bruxism correlated with emotional parameters, whereas no significant difference in sleep bruxism was observed in males throughout the stages of the study. The manual years of dental education were found to be linked to higher levels of emotional distress and awake bruxism, particularly in men. Sleep bruxism, on the other hand, was not directly linked to emotional factors, implying a distinct etiology.

Temporomandibular Disorders and Bruxism Outbreak as a Possible Factor of Orofacial Pain Worsening during the COVID-19 Pandemic-Concomitant Research in Two Countries.

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.

Burnout and professional quality of life among Israeli dentists: the role of sensory processing sensitivity.

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.
