“…Slight agitation of dye solution will eliminate any trapped air and contact with bacteria will be more predictable [12]. For enhanced effects a radial firing tip with optimum emission pattern of light should be used [54]. This will also result in even distribution of light and eradication of bacteria up to a depth of 1mm ensuring effective disinfection of root canal system even in cases of persistent infection where microbes like E. faecalis may penetrate up to a depth of 150 µm [55,56].…”

“…It is also found that use of optical fiber for addition of aPDT within the root canal system is better than application of laser light directed at access cavity [53]. In a recent study, radial firing tip is found to be superior method of application of aPDT and significantly more viable E. faecalis were removed within the prepared root canals when compared to bare end fiber tips [54].

Elimination of root canal pathogens is one of the main objectives for successful outcome of root canal treatment. Conventional chemo-mechanical debridement is not always successful in removing all bacteria. Adjunctive use of antimicrobial photodynamic therapy (aPDT) can be a used as a practical approach for successful elimination of all these bacteria. The aim of this review was to assess scientific literature that used various photosensitizers for bacterial reduction using aPDT methods. A search of the PubMed and Cochrane data bases using appropriate terms and keywords related to antimicrobial photodynamic therapy in endodontic disinfection was conducted. A hand search also was conducted in the preceding 5 years of several journals. Full texts of the selected articles were obtained and analyzed. A total of 177 articles published were identified at first stage of data extraction. After final screening, 41 articles were included in this review. This review summarizes the usage principles of aPDT and outlines the applications of aPDT in root canal disinfection procedures. It was concluded that aPDT should be used in conjunction with the conventional chemo mechanical debridement and disinfection of root canal system. It is critical to note that selection of photosensitizer dye, its correct delivery within the prepared root canal system, laser application with correct type of tips are predictors for successful outcome of this protocol of root canal disinfection.

“…[17][18][19] Diode lasers (810, 940 and 980 µm wavelengths) display huge water transmission, reaching the bacteria in deeper layers of dentinal tubules in result. 20 Schulte-Lunzum et al 21 demonstrated that 940 nm diode laser has an intensely high bactericidal effect on Enterococcus faecalis which is the most isolated microorganism in failing endodontic cases, even at the 1000 µm depth of dentinal tubules.…”

Background: This study aims to assess the effect of root canal disinfection with a 980 µm diode laser following chemomechanical root canal preparation on the severity of pain after root canal treatment (RCT).Methods: In present study, asymptomatic, single-rooted teeth with periapical index (PAI) score 3 or 4 were included. All patients were treated with two visits of root canal treatment including dressing with calcium hydroxide. Patients were randomly divided into two groups (n: 28). ‘Control (no laser)’: The final irrigation was performed using 5ml 2.5% NaOCI, followed by 5 ml 17% EDTA and 5 ml distilled water. ‘Laser Disinfection (LD)’: Root canals were irradiated with 980 µm diode laser after final irrigation at both visits. The pain levels were evaluated using visual analog scale (VAS) after 8, 24, 48 hours and 7 days. In addition, analgesic intake and time intervals were recorded by patients. The collected data were statistically analyzed with the Chi-square and Mann-Whitney U test (p<0.05).Results: The average pain level in the control group after 24 hours was significantly higher than that in the laser group after the first appointment (p<0.05). The average pain level after the second appointment was statistically higher at 24 h and 48 h in the control group (p<0.05). PP levels at 24-hs after the first appointment were higher than the second appointment only in the control group (p<0.05). After first appointment, analgesic use in the control group at 8 h (40%) and 24 h (23%) were significantly higher than LD group (p<0.05).Conclusions: Root canal disinfection with diode laser may reduce PP in single-rooted teeth with PAI score 3 or 4.Trial registration: Effect of the Diode Laser on Post-operative Pain After Endodontic Treatment in Teeth with Apical Periodontitis: NCT04486196.

“…Since diode laser does not damage the dental hard tissues, it is effective on microorganisms in dentinal tubules (de Souza et al, 2008). A study showed that diode laser irradiation provides has high bactericidal effect against Enterococcus faecalis, the bacteria that are the most difficult to eliminate, even at the 1000-μm depth of dentine (Schulte-Lunzum et al, 2017).…”

Objective: The present study aimed to evaluate the association between pain during intracanal diode laser irradiation in mandibular molar teeth have symptomatic apical periodontitis and factors such as demographic and preoperative factors. Methods: Fourteen patients who have mandibular molar teeth have symptomatic apical periodontitis were enrolled in this clinical study. All endodontic treatments were performed in one-visit. After final irrigation, root canals were irradiated using a 970 ± 15 nm diode laser with a 14 W maximum power. Pain during laser application, postoperative pain levels at day 1, 3, 5, 7 and 30 and postoperative percussion tenderness levels at day 7 on the visual analog scale were marked. Multiple lineer regression was used for constructing a predictive model for intraoperative pain (P = 0.05). Results: 11 (78 %) patients reported pain during intracanal diode laser application. Age, gender, tooth type (first molar or second molar), side of the tooth (left or right), preoperative palpation, pulp status, preoperative percussion and preoperative spontaneous pain did not predict intraoperative pain during intracanal diode laser application (F(8, 5) = 2.332, p > .05). Conclusion: Within the limitations of the present clinical trial, none of the factors predict intraoperative pain during intracanal diode laser application.
