The occurrence of epidermoid cysts in the oral cavity is extremely rare. These cysts generally present slow and progressive growth and often are not diagnosed until the second or third decade of life. ⋯ After surgical removal of the cyst, histopathologic examination confirmed the diagnosis of epidermoid cyst. Characteristics of epidermoid cysts are described and surgical treatment discussed.

Randomized Controlled Trial
Clinical evaluation of different gingival retraction cords.
Impression techniques in restorative dentistry require displacement of gingival tissues to expose subgingival finish lines on tooth preparations. Retraction cords are commonly used for this purpose. Some cord systems include various medicaments, which may remain in the sulcus after retraction procedures. The purpose of this study was to determine whether any of the commonly used gingival retraction medicaments could influence the surface characteristics of the impression material and to evaluate the clinical performance of retraction cords. ⋯ The applied gingival retraction cord systems had no influence on the surface characterization of the polyvinyl siloxane material tested. Gingival margin quality of the impression and clinical application procedures were affected by the retraction systems. Untreated, medium-braided, and epinephrine-impregnated cord systems were clinically successful. However, the potential systemic effects of epinephrine must be considered.

Comparative Study
Pain-related impairment and health care utilization in children and adolescents: a comparison of orofacial pain with abdominal pain, back pain, and headache.
The purpose was to compare orofacial (temporomandibular) pain with other pain complaints regarding impairment and health care utilization in a sample of 1,011 children and adolescents from a metropolitan area in Germany. ⋯ In children and adolescents, orofacial pain occurs about half as often as other pain complaints. However, relative to their prevalence the different pain complaints are similar regarding impairment and health care utilization.

The maxillary (or second division) nerve block is an effective method of achieving profound anesthesia of a hemimaxilla. This block can be used for procedures involving the maxillary sinus, including the maxillary sinus elevation procedure. The purpose of this study was to evaluate a computer-controlled anesthetic delivery system (Wand) for maxillary nerve block injection to attain maxillary sinus anesthesia for sinus floor elevation procedure. ⋯ The Wand appears to offer a number of advantages over the hand-held syringe when the greater palatine block technique for the maxillary nerve block is used. It is suggested that, when indicated, and with the required knowledge and respect for the associated anatomy, this technique should be considered with greater ease and more confidence.
