“…The results of our study agree with the findings of Arsalan A et al [ 21 ] and Çakici E [ 35 ] where both concluded that low-level laser therapy reduced postoperative pain after single visit. LLLT is deemed as non-invasive therapies by light [ 7 ] embody the principle of phototherapy and contribute to the same concept of photobiomodulation [ 8 ].…”

Objectives As post-endodontic pain control is one of the main targeted addressed in endodontics, our aim was delignated to compare two different methods for low-level laser application utilizing diode laser: low-level laser therapy (LLLT) and laser-activated irrigation (LAI) in the control of post-endodontic pain. Materials and subjects A total of 180 patients received single-visit root canal treatment; they were randomly allocated into 3 equal groups. Group I received LAI, group II received LLLT, and group III served as control with normal root canal treatment and mock laser intervention (ML group). Postoperative pain was recorded using visual analogue scale (VAS) after 24, 48, and 72 h. Data were tabulated and statistically analyzed. Results At 24 h, there was a statistically significant difference between median pain scores in the three groups (P value < 0.001) with ML group scored highest score followed by LAI and then LLLT group. At 48 h, there was a statistically significant difference between the three groups (P value < 0.001), with ML group scoring highest median pain scores while LLLT and LAI showed statistical insignificant scores. At 72 h, there was no statistically significant difference between the 3 groups (P value = 0.179). Conclusion LLLT is superior to LAI and ML group in the control of immediate postoperative pain after 24 h while after 48 h both LAI and LLLT were equally effective, but they still showed significant differences when compared to ML group. Clinical relevance Diode laser can be used by clinicians as it decreases the post-endodontic pain in patients with symptomatic apical periodontitis undergoing endodontic treatment.

Objectives Effective disinfection of the root canals is the cornerstone of successful endodontic treatment. Diminishing the microbial load within the root canal system is crucial for healing in endodontically treated teeth. The aim of this study was to evaluate the effect of 2780 nm Er,Cr:YSGG and 940 nm diode lasers on the eradication of microorganisms from single-rooted teeth with asymptomatic apical periodontitis. Materials and Methods Thirty participants conforming to the inclusion criteria were randomly divided into 3 groups according to the disinfection protocol used; Conventional group: 2.5% Sodium Hypochlorite (NaOCl) and 17% EDTA solution NaOCl/EDTA, Dual laser group: 2780 nm Erbium, chromium: yttrium scandium-gallium-garnet (Er,Cr:YSGG) laser and 940 nm diode laser Er,CrYSGG/Diode, and Combined group: 17% EDTA and 940 nm diode laser EDTA/Diode. Bacterial samples were collected before and after intervention. The collected data were statistically analyzed using Friedman’s test and Kruskal–Wallis test (P ≤ 0.05). Results The results of the study showed that both dual laser Er,CrYSGG/Diode and combined laser EDTA/Diode groups showed significantly less mean Log10 CFU/ml of aerobic and anaerobic bacterial counts than the conventional NaOCl/EDTA group. Conclusions In this study we evaluated in vivo the bactericidal efficacy of three disinfection protocols for endodontic treatment of single-rooted teeth with apical periodontitis. The results indicated that both dual laser Er,CrYSGG/Diode and combined laser EDTA/Diode groups provide superior bactericidal effect compared to the conventional NaOCl/EDTA group. Clinical relevance The integration of lasers into root canal disinfection protocols has demonstrated significant bacterial reduction which might promote healing and long-term success.

Background: This study aimed to assess the effectiveness of laser photobiomodulation (PBM) in reducing postoperative pain following single-visit endodontic treatment in children aged 5–9 years. Methods: Forty children aged 5–9 years with acute irreversible pulpitis in deciduous molars requiring single-visit pulpectomy were included in the study. Pulpectomy was performed according to a standard endodontic protocol. The participants were randomly allocated to two groups: group A received laser photobiomodulation using an 810 nm diode laser applied to the periapical area of the treated tooth postoperatively, and group B received blue light LED, applied at similar points to the control teeth. This was a placebo intervention. Pain scores were measured using a 10-point Visual Analog Scale (VAS) at 4, 12, 24, and 48 h post-treatment. The Friedman test was used to compare the VAS scores within groups over time, and the Mann–Whitney U-test was used to compare the VAS scores between the two groups. The significance level was fixed at p < 0.05. Result: The mean VAS scores were significantly lower in the PBM group compared to the placebo group at the 4th h, 12th h, and 24th h post-treatment (p ≤ 0.05). The pain levels remained stable over time in the PBM group, with no significant difference in pain scores from 4 h to 48 h (p = 0.57). In the placebo group, the pain gradually decreased from the 4th h to the 48th h, with a significant reduction in pain observed between the 12th h and 48th h (p = 0.05). Conclusions: Laser photobiomodulation (PBM) was found to be effective in reducing postoperative pain following single-visit endodontic treatment in children. This non-invasive approach could offer a valuable alternative for pain management in pediatric endodontics, particularly given its effectiveness without the need for systemic medications.
