In Vitro Effect of Laser Irradiation on Cementum‐Bound Endotoxin Isolated From Periodontally Diseased Roots

Abstract

The Nd:YAG laser varying from 50 mJ, 10 pps to 150 mJ, 20 pps, for 2 minutes, did not seem to be effective in destroying diseased cementum endotoxin.

Lasers in nonsurgical periodontal therapy

“…Liu et al. (110) explored the in vitro effectiveness of the Nd:YAG laser for the elimination of cementum‐bound endotoxin by measuring interleukin (IL)‐1β changes in stimulated monocytes. Nd:YAG laser varying between 50 mJ/pulse and 10 Hz and 150 mJ/pulse and 20 Hz for 2 min did not seem to be effective in destroying diseased cementum endotoxin.…”

Silica nanoparticles containing nano-silver and chlorhexidine to suppress Porphyromonas gingivalis biofilm and modulate multispecies biofilms toward healthy tendency

“…One hundred microliters of supernatant was added to an endotoxin-free tube and mixed with 100 µL of Limulus reagent. In the presence of endotoxins, the factors in LAL kits were activated in a proteolytic cascade that result in the cleavage of a colorless artificial peptide substrate [ 51 ]. Operated according to the operation manual and measured the absorbance at 545 nm.…”

Nd:YAG lasers in nonsurgical periodontal treatment - a literature review

“…Liu et al (4) investigated the effect of Nd:YAG laser on the endotoxin in extracted teeth due to periodontal disease. They found that the laser itself could not produce temperature high enough to remove cement-bound endotoxin and at the same time be in safe clinical limits.…”
