However, no studies have compared the effects of newly marketed video laryngoscopes and the Macintosh laryngoscope (Mac) on teeth. In this study, we measured and compared the force exerted on the teeth of an intubating manikin by the Mac, the Airway Scope (Pentax), and the McGrath MAC (Covidien). The mean force exerted was 141.1 \u00b1 15.7 kg by the Mac, 39.2 \u00b1 10.3 kg by the Airway Scope, and 48.7 \u00b1 6.7 kg by the McGrath MAC. No significant difference was observed between the Airway Scope and the McGrath MAC. When the Mac is inserted, the glottis has to be visually located from outside the oral cavity. However, a significant force is not necessary when inserting video laryngoscopes because a camera is mounted on the blade tip. In this laboratory model, the lower force exerted by the video laryngoscopes should contribute to a reduction in their impact on fracture or dislocation of teeth.<\/jats:p>","DOI":"10.2344\/anpr-65-03-01","type":"journal-article","created":{"date-parts":[[2018,9,20]],"date-time":"2018-09-20T21:21:11Z","timestamp":1537478471000},"page":"151-155","source":"Crossref","is-referenced-by-count":10,"title":["Comparison of the Contact Force Exerted on Teeth by Conventional Macintosh Laryngoscope Versus Video Laryngoscopes"],"prefix":"10.2344","volume":"65","author":[{"given":"Yasuhiko","family":"Kato","sequence":"first","affiliation":[{"name":"Associate Professor, Department of Anesthesiology, Osaka Dental University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasushi","family":"Sakuma","sequence":"additional","affiliation":[{"name":"Associate Professor, Department of Anesthesiology, Osaka Dental University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshihiro","family":"Momota","sequence":"additional","affiliation":[{"name":"Professor, Department of Anesthesiology, Osaka Dental University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1191","reference":[{"key":"i0003-3006-65-3-151-b01","series-title":"J Clin Anesth","first-page":"339","article-title":"Dental injury associated with anesthesia: a report of 161,687 anesthetics given over 14 years","volume":"19","author":"Newland \n              MC,","year":"2007","unstructured":"Newland \n              MC, \n            \n            \n              Ellis \n              SJ, \n            \n            \n              Peters \n              KR, \n            \n            et al. \n          Dental injury associated with anesthesia: a report of 161,687 anesthetics given over 14 years.
