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.
