Randomized Controlled Trial
Efficacy of 1% ropivacaine gel for topical anesthesia of human oral mucosa.
To evaluate the efficacy of 1% ropivacaine for topical anesthesia in dentistry. ⋯ All topical anesthetics were similar in reducing pain to needle insertion. EMLA-60 promoted longer duration of soft tissue anesthesia.

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.

Randomized Controlled Trial Comparative Study Clinical Trial
The use of sterile versus nonsterile gloves during out-patient exodontia.
One hundred twenty-four patients who showed no clinical evidence of acute infection, were not taking antibiotics, and were to undergo routine removal of erupted teeth were studied. Patients were alternately assigned to surgeons who were wearing sterile or nonsterile, but clean, gloves. ⋯ None of the patients was found to be infected postoperatively. Results of this prospective study suggest that routine exodontia can be safely performed by a surgeon wearing nonsterile, but surgically clean, gloves without increasing the risk of postoperative infection.
