Single-file systems have recently appeared, with the aim of reducing the number of steps and files to reach a correct endodontic treatment. The purpose of this study was to evaluate by SEM the root canal walls after instrumentation with F360 (Komet, Brasseler GmbH & Co., Lemgo, Germany) and F6 Skytaper (Komet, Brasseler GmbH & Co., Lemgo, Germany), in order to evaluate the presence/absence of smear layer and the presence/absence of open tubules on the root canal walls at coronal, middle, and apical third of each sample.\u0000\u0000\u0000METHODS\u0000Twenty single-rooted freshly extracted teeth were selected and divided into 2 groups. For each group root canals were shaped with F360 (Komet, Brasseler GmbH & Co., Lemgo, Germany) and F6 Skytaper (Komet, Brasseler GmbH & Co., Lemgo, Germany) instruments under irrigation with 5,25% NaOCl and 17% EDTA. Specimens were fractured longitudinally and analyzed by SEM at standard magnification of 5000x. The presence/absence of smear layer and the presence/absence of open tubules at the coronal, middle, and apical third of each canal were evaluated using a 5-step scale for scores.

Each member of the study group was required to answer questions regarding the clinical management of OSAS and snoring.\u0000\u0000\u0000RESULTS\u0000Oral appliances can be used to treat: - simple snoring, in patients who do not respond to, or do not appear to be suitable candidates for behavioral measures such as weight loss or positional therapy; - mild or moderate OSAS, in patients who prefer OAs to continuous positive airway pressure (CPAP) or who are not suitable candidates for CPAP, because of its failure or failure of behavioral approaches like weight loss or positional therapy; - severe OSAS, in patients who do not respond to or do not tolerate CPAP and in whom no indication for either maxillofacial or ENT surgery appears applicable.\u0000\u0000\u0000CONCLUSIONS\u0000The application of oral appliances is highly desirable in cases of simple snoring or mild to moderate OSAS, whereas considerable caution is warranted when treating severe OSAS.
