TMD—a world of difference: A case study

The case study presented in this course shows how important the proper function of the temporomandibular joint is to quality of life.

The temporomandibular (TMD) joint is a unique joint that can become damaged or dysfunctional as the result of many physiologic problems, including estrogen and vitamin deficiencies. TMD joint dysfunction can result in systemic symptoms that often appear unrelated such as tinnitus, headaches, and motion sickness. The case study presented in this course shows how important the proper function of the temporomandibular joint is to quality of life. By paying close attention to our patients’ chief complaints, we can aid in the timely diagnosis and treatment of temporomandibular joint dysfunction.

Educational objectives

Upon completion of this course, the dental professional should be able to:

  • Describe the symptoms of temporomandibular joint dysfunction
  • Investigate how estrogen deficiencies may influence myofascial disorders in patients
  • Strategize assessment of treatment approaches to increase success in temporomandibular joint dysfunction patient care
  • Provide information related to an individual case study that may improve dental professionals’ assessment and treatment options for patients
