Arthrocentesis versus nonsurgical methods in the management of temporomandibular joint closed lock and pain: a double-blind randomized controlled trial.

OBJECTIVE: The present double-blind randomized clinical trial aimed to compare the efficacy of conservative treatment and articular lavage, either alone or combined, to reduce joint pain and improve mandibular opening. STUDY DESIGN: The sample consisted of patients presenting with limited mouth opening and joint pain. The diagnosis was made according to the diagnostic criteria for temporomandibular disorders guideline and confirmed by magnetic resonance imaging. Sixty patients were selected and randomly allocated to 4 groups of 15 patients each with different treatments: group A (conservative), group B (conservative + medication), group C (arthrocentesis), and group D (arthrocentesis + medication). The groups were compared in terms of maximal interincisal opening and pain. RESULTS: The average age of the patients was 34.17 ± 13.1 years, 88.1% were women, 72.9% had internal derangement, 54% had joint sounds, and 55.9% presented with locking. Clinical improvement was noted in all parameters compared with baseline in all groups (P < .005), but no significant differences were observed when the groups were compared (P > .05). CONCLUSIONS: Both arthrocentesis and conservative modalities were efficient treatments to reduce joint pain and increase mandibular opening.

Myiasis in palate by Cochliomyia hominivorax.

Myiasis is the infestation of tissues and organs of animals and humans caused by the larvae of certain dipteran flies. It is more common in undeveloped and tropical countries and usually affects elderly patients, persons who are sick, and patients with mental illness. Oral myiasis is a rare pathologic condition and a risk to the patient's life because of its great destructive potential. Therefore, appropriate treatment is necessary. This article aimed to report a case of myiasis caused by Cochliomyia hominivorax in the palate of a patient with primary progressive aphasia, which was successfully treated through mechanical removal of larvae plus administration of ivermectin.
