Randomized Controlled Trial Comparative Study
Comparing anesthetic efficacy of articaine versus lidocaine as a supplemental buccal infiltration of the mandibular first molar after an inferior alveolar nerve block.
The authors conducted a prospective, randomized, double-blind, crossover study comparing the degree of pulpal anesthesia achieved by means of mandibular first molar buccal infiltrations of two anesthetic solutions: 4 percent articaine with 1:100,000 epinephrine and 2 percent lidocaine with 1:100,000 epinephrine after an inferior alveolar nerve (IAN) block with the use of 4 percent articaine with 1:100,000 epinephrine. ⋯ For a mandibular buccal infiltration of the first molar after a standard IAN block, 4 percent articaine with 1:100,000 epinephrine resulted in a higher success rate (88 percent) than did 2 percent lidocaine with 1:100,000 epinephrine (71 percent success rate).

Comparative Study
Toothache pain: a comparison of visits to physicians, emergency departments and dentists.
Researchers' understanding of the use of emergency departments (EDs) and physicians' offices for the treatment of toothaches is limited. The authors conducted a study to explore their use by low-income and minority adults in comparison with the use of traditional dental services. ⋯ The elimination of oral health disparities must involve consideration of cultural influences on minority populations, as well as the responsibilities of the dental profession.
