Temporomandibular Joint Pain: Diagnostic Characteristics of Chronicity

Disease Phobia in Patients with Temporomandibular Joint Pain Assessed by the Illness Attitude Scale

Disease phobia refers to a psychological state when the person continuously thinks that he/she is sick and improvement from the condition is impossible. Disease phobia in patients suffering from pain, secondary to temporomandibular disorders (TMDs), is usually the consequence of long-term problems; diagnosis and treatment of this group is a real challenge for healthcare professionals.

AIM

The purpose of this prospective study was to objectively evaluate the role of Illness Attitude Scale (Kellner or IAS) in measuring cancerophobia and heart disease phobia in patients suffering from pain, as a consequence of TMDs.

SUBJECTS AND METHODS

The cohort included 22 patients with TMDs who underwent evaluation of these phobias; pain was acute in 7 and chronic in 15. The patients were asked to complete the "Kellner" questionnaire, and this was followed by full clinical examination of the temporomandibular region.

RESULTS

When measuring the correlation between the cancerophobia and heart disease phobia patients, the outcome was found significant in the total cohort, p<0.01. Comparisons were carried out in the chronic group (n=15) and was significant (p=0.034 and r=0.549); while in the acute group no significance was identified.

CONCLUSION

Cancerophobia and heart disease phobia in TMD patients are factors that need to be taken in consideration when managing chronic pain in this group.

Soft versus hard occlusal splint therapy in the management of temporomandibular disorders (TMDs)

Aim

To compare between soft and hard occlusal splint therapy for the management of myofacial pain dysfunction (MPD) or internal derangement (ID) of the temporomandibular joint (TMJ) with reciprocal clicking.

Patients and methods

This study included 50 patients (age range: 24–47 years) who had been diagnosed with MPD or ID of the TMJ in the form of reciprocal clicking. Patients were divided into two groups. They were treated for 4 months with either a vacuum-formed soft occlusal splint constructed from 2-mm-thick elastic rubber sheets (soft splint group) or a hard flat occlusal splint fabricated from transparent acrylic resin (hard splint group). Monthly follow-up visits were performed during the treatment period. Before treatment and 1, 2, 3 and 4 months after treatment, the dentist measured all parameters of TMJ function (pain visual analog scores, tenderness of masticatory muscles, clicking and tenderness of the TMJ, and range of mouth opening).

Results

All parameters of TMJ function showed significant improvement in both groups during the follow-up period, with a statistically significant difference between the two groups at the 4-month follow-up visit.

Conclusions

Both forms of occlusal splints (soft and hard) improved TMJ symptoms in patients with MPD or ID of the TMJ. However, the soft occlusal splints exhibited superior results after 4 months of use.
