Outcome of three screening questions for temporomandibular disorders (3Q/TMD) on clinical decision-making

Abstract

Patients with temporomandibular disorders (TMD) seem to go undetected and not adequately managed within dentistry. To identify these patients, three screening questions (3Q/TMD) have been introduced within dentistry in parts of Sweden. It is not known whether 3Q/TMD affects the clinical decision-making for these patients.

Objectives

To evaluate the outcome of 3Q/TMD on the clinical decision-making, and to analyse if gender, age, and the fee-system the individual was assigned to, were related to prescribed TMD treatment.

Methods

This cohort study was carried out within the Public Dental Health service in Västerbotten, Sweden. As part of the routine dental check-up, a health declaration including 3Q/TMD was completed. The study population was randomly selected based on their 3Q/TMD answers. In total, 300 individuals with an affirmative answer to any of the 3Q/TMD, and 500 individuals with all negative answers were selected. The 3Q/TMD includes questions on weekly jaw-face-temple pain (Q1), pain on function (Q2), and catching/locking of the jaw (Q3). The 3Q/TMD was analysed in relation to prescribed treatment assessed from dental records.

Results

There was significantly more treatment performed or recommended for 3Q-positives (21.5%), compared to 3Q-negatives (2.2%) (P<0.001). The odds ratio for TMD-related treatment for 3Q-positives versus 3Q-negatives was 12.1 (95% CI:6.3-23.4).

Conclusion

Although affirmative answers to the 3Q/TMD was related to TMD treatment, the majority of individuals with a screen positive still did not, according to dental records, receive assessment or treatment. Further studies are needed to better understand the clinical decision-making process for patients with TMD.
