RESUMO
PURPOSE: The purpose of this study was to evaluate whether the anesthetic efficiency of articaine is superior to that of lidocaine during lower third molar extraction (LTME). MATERIALS AND METHODS: Three electronic databases (PubMed, Cochrane, and Web of Science) were searched to identify randomized controlled trials up to December, 31 2017. Five evaluation indexes were extracted, namely success rate of anesthesia, subjective onset time of anesthesia, objective onset time of anesthesia, duration time of anesthesia, and intraoperative pain assessment, to assess the anesthesia efficiency of the 2 solutions. All data analyses were conducted using Review Manager (version 5.3; The Cochrane Collaboration, London, United Kingdom). RESULTS: Nine studies were included in this review. The sample was composed of 770 LTMEs from 493 patients, with 382 LTMEs in the lidocaine group and 388 LTMEs in the articaine group. Compared with lidocaine, 4% articaine with 1:100,000 epinephrine showed a higher success rate of anesthesia (risk ratio, 1.10; 95% confidence interval [CI], 1.01 to 1.21; P = .03), shorter subjective onset time of anesthesia (standardized mean difference, 1.20; 95% CI, 0.50 to 1.89; P = .0007), and longer duration time of anesthesia (mean difference, 0.83 hours; 95% CI, 0.59 to 1.07 hours; P < .00001); however, for intraoperative pain assessment (mean difference, 3.12 mm; 95% CI, -0.13 to 6.37 mm; P = .06) and objective onset time of anesthesia (standardized mean difference, 0.44; 95% CI, -0.39 to 1.26; P = .30), there was no significant difference between the 2 solutions. CONCLUSIONS: The results of this study suggest that 4% articaine with 1:100,000 epinephrine possesses superior anesthetic efficiency relative to lidocaine for inferior alveolar nerve blocks during LTME.

Although radiography is a first-line test for the assessment of bone lesions, MR imaging is needed for defining the extent of a bone tumor. In addition, MR imaging provides features and metrics for the characterization of bone lesions as well as for the evaluation a tumor following treatment. There are several noncontrast and contrast-enhanced sequences available for clinical use that collectively provide valuable information for tumor evaluation, and include conventional T1-weighted imaging, fluid-sensitive sequences, chemical shift imaging, and diffusion-weighted imaging with ADC mapping, as well as postcontrast sequences, including static postcontrast imaging and dynamic contrast-enhanced MR imaging.
