Summary
Myofascial pain-dysfunction syndrome can be divided into myogenic facial pain (MFP) and TMJ internal derangement (TMJID) groups. These groups show distinct psychometric differences, with MFP and atypical facial pain (AFP) patients exhibiting higher psychopathology scores.
Area of Science:
- Dentistry
- Pain Medicine
- Psychology
Background:
- Myofascial pain-dysfunction syndrome and atypical facial pain are common chronic facial pain disorders.
- Previously, myofascial pain-dysfunction syndrome encompassed temporomandibular joint (TMJ)/masticatory muscle pain, jaw dysfunction, and joint clicking.
- This study segregates these into myogenic facial pain (MFP) and TMJ internal derangement (TMJID) groups.
Purpose of the Study:
- To differentiate between subgroups within myofascial pain-dysfunction syndrome.
- To investigate age, personality, and psychometric differences between MFP, TMJID, and atypical facial pain (AFP) groups.
Main Methods:
- Comparison of age and personality traits between MFP, TMJID, and AFP subjects.
- Analysis of Minnesota Multiphasic Personality Inventory (MMPI) psychometric scales across the groups.
Main Results:
- MFP and TMJID groups are younger than the AFP group.
- MFP and AFP subjects showed significantly higher MMPI scores for hypochondriasis, depression, and hysteria compared to TMJID subjects.
- Psychopathological factors are more pronounced in MFP and AFP patients than in TMJID patients.
Conclusions:
- Subcategorization of myofascial pain-dysfunction syndrome into MFP and TMJID groups is supported by psychometric differences.
- Psychopathological factors play a more significant role in MFP and AFP than in TMJID.
