PURPOSE: The purpose of the present study was to assess the safety and efficacy of oral diclofenac potassium liquid-filled soft gelatin capsule (DPSGC) that uses ProSorb dispersion technology (Xanodyne Pharmaceuticals, Inc, licensed from AAIPharma, Wilmington, NC), to treat adult patients with acute pain after third molar extraction. PATIENTS AND METHODS: In the present multicenter, randomized, double-blind, placebo-controlled trial, patients experiencing a baseline level of pain (>/= 50 mm on a 100-mm visual analog scale within 4 hours after surgery) were randomized to receive a single dose of DPSGC at 25, 50, or 100 mg or placebo. Pain intensity and relief were assessed for 6 hours after dosing. The efficacy endpoints included the summed pain intensity difference, total pain relief, and the median time to the onset of perceptible and meaningful pain relief (using the 2-stopwatch method). RESULTS: A total of 249 randomized patients had a significant increase in the summed pain intensity difference and total pain relief values at 3 and 6 hours across all DPSGC-treated groups compared with the placebo group (P < .0001). The onset of perceptible and meaningful pain relief was significantly faster in all DPSGC groups than in the placebo group, including the DPSGC 25-mg group (25 minutes [P = .0002] and 52 minutes [P < .0001] for perceptible and meaningful pain relief, respectively). Significantly fewer patients in the DPSGC groups required rescue medication compared with those in the placebo group (P < .0001). The global evaluation scores were significantly greater for the patients who received DPSGC than for those who received placebo (P < .0001), and more than 65% of DPSGC-treated patients rated the medication as good, very good, or excellent compared with 18% of the placebo-treated patients. DPSGC was generally well tolerated, and no serious adverse events were reported. CONCLUSIONS: The results from the present single-dose study of postoperative dental pain suggest that DPSGC offers significant pain relief compared with placebo and that the study medication provided was well tolerated by patients who required pain relief after third molar extraction

BACKGROUND AND OBJECTIVE: The most common risk factor for bisphosphonate-related osteonecrosis of the jaws (BRONJ) is dentoalveolar surgery. It has been suggested that reduced serum C-terminal telopeptide (CTX) can determine the degree of osteoclast suppression and may predict the development of BRONJ after dentoalveolar surgery. Although there are many radiographic appearances associated with BRONJ, there are little data that describes changes preceding dentoalveolar surgery. The objective of this retrospective study was: 1) to investigate if reduced serum CTX values (i.e., <150 pg/mL) were associated with BRONJ after dentoalveolar surgery; and 2) to determine if specific radiographic changes are associated with teeth that develop BRONJ after extraction. STUDY DESIGN: A retrospective review of radiographic and/or serum CTX data was performed for 68 patients with a history of bisphosphonate therapy who either underwent dental extraction or were diagnosed with BRONJ in the Department of Oral and Maxillofacial Surgery during the period 2007-2009. Postoperative healing was assessed for 26 patients with reduced serum CTX levels (<150 pg/mL) who either underwent dental extraction or treatment for BRONJ. Preoperative radiographs were evaluated for 55 patients who either healed normally or developed BRONJ after dental extraction. RESULTS: All 26 patients (100%) who had serum CTX levels <150 pg/mL healed successfully after dentoalveolar surgery (20 patients) or after treatment for BRONJ (6 patients). Among the 55 patients who underwent radiographic evaluation, 24 patients (83%) with BRONJ exhibited periodontal ligament (PDL) widening associated with extracted teeth, whereas only 3 patients (11%) who healed normally demonstrated PDL widening. CONCLUSION: These data suggest that radiographic PDL widening may be a more sensitive indicator than CTX testing in predicting risk of BRONJ. Current guidelines that recommend minimal surgical intervention may need to be revised to include alternative strategies for the elimination or management of this pathology.

Salivary gland infections arise from a wide variety of etiologies: bacteria, localized viruses, systemic viruses, autoimmune diseases, secondary to sialoliths and strictures, and congenital disorders. When dealing with these entities, the diagnosis of the majority of them can be made quickly, although some of the rarer diseases are more difficult to recognize, particularly when they have a more obvious secondary bacterial infection. This article presents six cases and describes their management.
