Comparison between intra-articular platelet-rich plasma injection versus hydrocortisone with local anesthetic injections in temporomandibular disorders: A double-blind study.

Introduction: Temperomandibular joint (TMJ) is subjected to many disorders commonly called Temperomandibular disorders (TMDs); such as TMJ hypermobility, ankylosis, internal derangement, degenerative joint disease. Internal derangement is characterized by abnormal relationship of articular disc to the condyle and disc to fossa. In past many non-invasive conservative treatment modalities were tried out for its treatment which are joint unloading, use of anti-inflammatory agents, physiotherapy etc.

"Sodium bicarbonate": an adjunct to painless palatal anesthesia.

Purpose: It is believed that whenever we inject local anesthesia into the palate it is a painful experience for the patients. The aim of this study was to make palatal anesthesia painless by adding 7.4% sodium bicarbonate as an adjunct in local anesthesia.
