Pain relief following a single-dose intra-articular injection of methylprednisolone in the temporomandibular joint arthralgia-A multicentre randomised controlled trial.

Background: Temporomandibular joint (TMJ) arthralgia is a painful condition assumed to be associated with local inflammation.

Objective: The objective of the present study was to determine the efficacy for reducing pain of a single-dose intra-articular (IA) injection of methylprednisolone to the TMJ. The hypothesis was that methylprednisolone would effectively reduce TMJ pain.

Use of bibloc and monobloc oral appliances in obstructive sleep apnoea: a multicentre, randomized, blinded, parallel-group equivalence trial.

Background: The clinical benefit of bibloc over monobloc appliances in treating obstructive sleep apnoea (OSA) has not been evaluated in randomized trials. We hypothesized that the two types of appliances are equally effective in treating OSA.

Objective: To compare the efficacy of monobloc versus bibloc appliances in a short-term perspective.
