The authors conducted a systematic review and meta-analysis to determine whether arthrocentesis or arthroscopy combined with platelet-rich plasma (PRP) or platelet-rich growth factor (PRGF) injection compared with no injection or saline injection (control group) or hyaluronic acid (HA) injection reduced pain and increased maximum mouth opening (MMO) in patients with temporomandibular joint (TMJ) osteoarthritis (OA). ⋯ Although the results of the included studies showed that arthrocentesis or arthroscopy with PRP or PRGF, saline, or HA injections all reduced pain and increased mouth opening, the evidence was of very low quality. Further studies are needed to confirm these preliminary results showing that PRP or PRGF with arthrocentesis or arthroscopy significantly improved pain but did not increase MMO compared with findings in the control or HA groups.

In this study, the authors assessed the readability of online endodontic information in English and Spanish. ⋯ The internet is a useful tool for communicating with patients, but available endodontic information is difficult for laypeople to understand. Endodontists should produce relevant materials in plain language to overcome this problem.
