The In Vitro Effect of Laser Irradiation (Er:YAG and CO2) and Chemical Reagents (Hydrogen Peroxide, Sodium Hypochlorite, Chlorhexidine, or Sodium Fluoride) Alone or in Combination on Reducing Root Caries Bacteria

Abstract: (1) Lasers have been used for the treatment of dentinal hypersensitivity and bacterial reductions in periodontology. The purpose of this in vitro study was to evaluate the effect of Carbon Dioxide (CO2) and Erbium-doped Yttrium Aluminum Garnet (Er:YAG) lasers with chlorhexidine (CHX), hydrogen peroxide (H2O2), sodium hypochlorite (NaOCl), or sodium fluoride (NaF) on the viability of oral bacteria associated with root caries. (2) Streptococcus mutans, Streptococcus sanguinis, and Enterococcus faecalis were grow… Show more

“…[ 3 ] Therefore, rapid occlusion of the exposed DTs represents the primary therapeutic approach for DH treatment, effectively shielding the nerve fibers from external stimuli and providing fast alleviation of dental pain. [ 4 ] Despite the widespread use of traditional methods like filling restorations, [ 5 ] laser photodynamics therapy (PDT), [ 6 ] dentin adhesives, [ 7 ] and commercial desensitizing medications, [ 8 ] their effectiveness is limited by the narrow pore size of DTs (<3 µm) and the complex physiological conditions within, such as surface affinity. [ 9 ] In the dynamic oral environment, where teeth wear ranges from ≈15 µm per year under physiological conditions to 200 µm per year under pathological conditions, [ 10 ] methods like PDT might offer rapid pain relief but can cause dentinal cracks and collagen fiber degradation.…”
