Sodium hypochlorite accident resulting in life-threatening airway obstruction during root canal treatment: a case report.

Aim: This case report describes a serious and life-threatening complication of the use of sodium hypochlorite as an irrigation solution in root canal therapy.

Summary: This case report describes a hypochlorite accident that occurred in a healthy 42-year-old female who was undergoing routine root canal therapy for the lower right central incisor (tooth #41). After approximately 1 hour of irrigation with 3% sodium hypochlorite (for a total of 12 cc), the patient complained of severe pain and burning in the lip.

Preliminary evaluation of histological changes found in a mechanical arthropatic temporomandibular joint (TMJ) exposed to an intra-articular Hyaluronic acid (HA) injection, in a rat model.

Objective: This study investigates the histological effects of Hyaluronic acid injections in the treatment of induced temporomandibular joint (TMJ) osteoarthritis in rats.

Study Design: Twenty-four male Wister rats were subjected to induced mechanical osteoarthritis by manual hypermobility for 10 successive days. Animals were then divided into two groups; group I (control) and group II (experimental).

Attenuation of C-reactive protein increases after exodontia by tramadol and ibuprofen.

The anti-inflammatory effects of ibuprofen and tramadol were investigated by measuring C-reactive protein concentrations after removal of an impacted lower third molar. Forty-five American Society of Anesthesiologists Class I patients were randomly categorized into 3 equal groups according to postoperative analgesic medication. The first group received tramadol (100 mg every 8 hours), the second group received ibuprofen (400 mg every 8 hours), and the last group received half doses of both drugs in combination (50 mg tramadol every 8 hours and 200 mg ibuprofen every 8 hours).

Imaging of temporomandibular joint ankylosis. A new radiographic classification.

Objectives: To compare the pre-operative clinical and radiographic findings of temporomandibular joint (TMJ) ankylosis with those found at operation and propose new classification.

Methods: Thirty-three patients were treated for TMJ ankylosis. There were 18 unilateral and 12 bilateral cases.
