Title No Difference Between Soft, Hard, Or No Occlusal Splint After Arthrocentesis For TMD In Short-Term Outcome
Clinical Question In an adult TMD patient with disc displacment without reduction being treated by arthrocentesis, does the use of a soft or hard splint affect the short-term outcome?
Clinical Bottom Line There is no difference between using soft, hard, or no occlusal splint after arthrocentesis procedure in short-term outcome (1 day, 1 month, 3 months, 6 months). (See Comments on the CAT below)

#1) 18356022Alpaslan/2008TMD patients diagnosed with disc displacement without reduction and arthrocentesis was planned as a first-line therapyRandomized Controlled Trial
Key results“Forty-five patients (41 female, 4 male) of the initial 67 patients, 22 in the hard splint group (mean age 29.8 ± 11.1 years; range 18-50 years), 9 in the soft splint group (mean age 31.6 ± 10.5 years; range 19-44 years) and 14 patients without a splint (mean age 28.9 ± 11.3 years; range 18–51 years), completed the 6-month follow-up period. There was a reduction in pain in all groups (P < 0.05) starting from the 1st day following arthrocentesis. There was no difference between the 3 groups in the decrease in pain. There was an increase in maximal mouth opening and lateral jaw movements in all groups (P < 0.05) following arthrocentesis at all time intervals. Between-group analysis did not show any differences.”

The Evidence
The number of patients in each of the groups tested are small and larger numbers would make this evidence stronger.

The search was replicated with the MESH terms in the CAT and the most relevant evidence was the same. This indicates that the CAT cites best available evidence for the given clinical question at the present time.
