Thermal Changes in the Hard Dental Tissue at Diode Laser Root Canal Treatment

Abstract

Summary.The laser coagulation at the apical part of the root canal after vital extirpation is a proper method of preventing complications such as pain, bleeding, remaining vital pulp. The aim of the present survey is to register the thermal changes that occur on the tooth surfaces during laser treatment of the root canal after vital extirpation. An in vitro study of 30 extracted teeth has been conducted. The teeth have been prepared with ProTaper nickel-titanium machine tools and wiped dry. During the course of laser treatment of root canals with a diode laser DenLase temperatures, changes of the surface of the hard dental tissues have been recorded with infrared camera FLIR T330. The captured thermal images have been processed with software product Flir Reporter Pro 9. In conclusion, temperature changes in hard dental tissues at diode laser treatment of the root canal are biocompatible.

The Effect of Two Lasers, Lx16, and Denlase on the Rise of Temperature on the External Root Surface of the Root Canals: An In Vitro Study

“…Laser systems, which emit nonionizing light with high energy concentration, have been studied as a therapeutic tool in endodontics [3]. Lasers are used in endodontics, specifically in root canal procedures, to address potential issues such as pain, vital pulp remnants, rest pulpitis, and bleeding [5]. Diode lasers, which emit light in the visible (mainly 660 nm) and infrared (810 to 980 nm) ranges of the electromagnetic spectrum, are commonly used for root canal disinfection [6].…”

Emissivity evaluation of human enamel and dentin

“…With increased interest in the use of infrared imaging devices to assess the temperature of mineralized tooth tissue, it is relevant to assess the emissivity of each sample to report a valid temperature. Many in vitro studies have been carried out with thermal imaging devices to assess potential damage to both the soft and mineralized tooth tissue from temperature changes, e.g., during laser application ( Launay, et al, 1987 ; Pogrel, et al, 1988 ; Anić, et al, 1993 ; Arima & Matsumoto, 1993 ; Neev, et al, 1993 ; Arrastia, et al, 1994 ; Anić and Matsumoto, 1995 ; Arrastia, et al, 1995 ; Machida, et al, 1995 ; Wilder-Smith, et al, 1995 ; Anić, et al, 1996a ; Anić, et al, 1996b ; Meyer & Foth, 1996 ; Neev, et al, 1996 ; Whitters & Strang, 2000 ; Yu, et al, 2000 ; Yamazaki, et al, 2001 ; Kishen, et al, 2003 ; Ishizaki, et al, 2004 ; Madura, et al, 2004 ; Wang, et al, 2005 ; Ana, et al, 2007 ; Da Costa Ribeiro, et al, 2007 ; Stock, et al, 2011 ; Da Silva Barbosa, et al, 2013 ; Uzunov, et al, 2014 ; Forjaz, et al, 2022 ), light-curing-composite ( Al-Qudah, et al, 2005 ; Bouillaguet, et al, 2005 ; Aksakalli, et al, 2014 ; Jo, et al, 2019 ; Mouhat, et al, 2021 ), endodontic treatment ( McCullagh, et al, 1997 ; McCullagh, et al, 2000 ; Behnia & McDonald, 2001 ; Lipski and Zapałowicz, 2002 ; Lipski & Woźniak, 2003 ; Lipski, 2004 ; Lipski, 2005a ; Lipski, 2005b ; Lipski, 2006 ; Hsieh, et al, 2007 ; Ulusoy, et al, 2015 ; Diegritz et al, 2020 ; Podolak, et al, 2020 ), pin-placement ( Biagioni, et al, 1996 ), post-removal ( Budd, et al, 2005 ; Lipski et al, 2010a ), cavity preparation and r...…”
