Randomized Controlled Trial
Do occlusal splints have an effect on complex regional pain syndrome? A randomized, controlled proof-of-concept trial.
Studies have suggested overlaps between various chronic pain conditions and painful temporomandibular disorders (TMDs). The objective of this pilot study was to assess the effectiveness of occlusal splint (OS) therapy on self-reported measures of pain in patients with chronic complex regional pain syndrome (CRPS) as compared with a nontreatment group. ⋯ The use of OS for 7 weeks has no impact on CRPS-related pain but improved signs and symptoms of TMD pain. Future studies should include an active control group and evaluate if long-term changes in measures of oral health impact general health in CRPS-related pain.

Randomized Controlled Trial
Multiple-day efficacy of parecoxib sodium treatment in postoperative bunionectomy pain.
To determine the analgesic efficacy of 1-day and multiple-day dosing regimens of parecoxib sodium (parecoxib) after bunionectomy in 2 randomized placebo-controlled studies. ⋯ Parecoxib treatment, in conjunction with supplemental analgesia given as needed, provided effective pain relief over 1 to 3 days in the bunionectomy model of postoperative analgesia. Bunionectomy is a useful model for testing multiple-day analgesic therapy.
