Ex Vivo Evaluation of Antibacterial Effects of Nd:YAG and Diode Lasers in Root Canals

Antimicrobial efficacy of a high‐power diode laser, photo‐activated disinfection, conventional and sonic activated irrigation during root canal treatment

“…, Gerek et al . ). Moreover, high‐power lasers have the potential to cause dentine charring, ankylosis, root resorption and periradicular necrosis (Bachall et al .…”

“…Its antimicrobial effectiveness against diverse microorganisms has already been demonstrated in previous studies (Gutknecht et al 2000(Gutknecht et al , 2004. Nevertheless, according to some, it was not more effective than NaOCl irrigation (Piccolomini et al 2002, Gerek et al 2010. Moreover, high-power lasers have the potential to cause dentine charring, ankylosis, root resorption and periradicular necrosis (Bachall et al 1992).…”

Effectiveness of Photodynamic Therapy AgainstEnterococcus faecalis,With and Without the Use of an Intracanal Optical Fiber: AnIn VitroStudy

“…In this context, high-power lasers have been shown to decrease the endodontic microbiota. 7,8 This decrease in the microbiota load is attributed to the high energy released through an intracanal optical fiber, destroying the microorganisms caused by an increase in temperature. 9,10 High-power lasers, however, have the potential to cause thermal injury to tissues, including carbonization of the dentin, root ankylosis, cementum melting, root resorption, and periradicular necrosis.…”

Bacterial Efficacy of Ca(oH) 2 Against E.faecalis Compared with three Dental Lasers on Root Canal Dentin- An Invitro Study

“…The presence of a smear layer after instrumentation reduces the effectiveness of irrigants and temporary dressings in disinfecting dentinal tubules. EDTA has the effect of removing smear layers,which helps the disinfection process in root canals [5,6].…”
