Temporomandibular Disorders: Why They Matter?
Temporomandibular Disorders (TMD) refer to a collection of dental and medical conditions affecting the temporomandibular joints (TMJ), masticatory muscles and / or associated structures. They are the most common cause of non-dental orofacial pain and are the second most widespread musculoskeletal pain after chronic lower back pain. In addition to pain in head, face and jaws, other TMD signs and symptoms include otic complaints, jaw joint sounds, jaw function difficulties, limited or abnormal jaw movements as well as catching/locking of the jaws. Population studies show that approximately 75% of people have signs while 33% have symptoms of TMD.
The biopsychosocial paradigm views a combination of biologic, psychological and social / cultural factors as essential in causing, maintaining and exacerbating TMD. Among the various factors, micro-trauma from sustained and repetitive adverse loading of the TMJ and masticatory muscles during Sleep Bruxism (SB) was reported to cause TMD. As SB has been related to Obstructive Sleep Apnea (OSA), it was proposed that the treatment of OSA and hence SB may alleviate TMD signs and symptoms. This two-part lecture aims to help participants know the current concepts of TMD, their classification, signs and symptoms and etiology. It also serves to introduce SB and OSA, and deliberates the potential connections between the three entities. Participants will learn how to screen for TMD, SB and OSA clinically. An overview of TMD management will also be presented. TMD patients should be referred for formal sleep tests if TMD signs and symptoms are associated with poor quality sleep, snoring, nocturnal choking and / or excessive daytime sleepiness.
Understanding and Managing the Anxious Dental Patient
Fear is an innate emotional response to threats, danger or pain while anxiety is the distress or uneasiness of mind caused by fear. Almost everyone experiences anxiety at some time or another. Most people have specific fears that can trigger panicked emotions. Dental anxiety has been ranked the fifth most commonly feared situation and is one of the primary reasons why people avoid visiting their dentists and oral health therapist. Dental anxiety may be related to the dental environment, specific dental procedures / pain and has been associated with poor oral health status, appointment failures, longer treatment time as well as reduced treatment satisfaction. This two-part lecture aims to help participants understand the psychology of anxiety and the behavioral, psychological and pharmacological techniques for helping anxious dental patients.
