Abstract Background: This study aimed to assess the effect of a 980-nm diode laser following chemomechanical root canal preparation on the severity of post-operative pain (PP) after root canal treatment (RCT).Methods: This study included asymptomatic, single-rooted teeth with a periapical index (PAI) score of 3 or 4. All the patients received RCT, including dressing with calcium hydroxide (Ca(OH)2), during two visits. The patients were randomly divided into two groups (n:30): a control group, in which the final irrigation was performed using 5 ml of 2.5% sodium hypochlorite (NaOCI), followed by 5 ml of 17% and ethylenediaminetetraacetic acid (EDTA) and 5 ml of distilled water, and a laser group, in which the root canals were irradiated using a 980-nm diode laser after the final irrigation at both visits. The pain levels after both visits were evaluated using a visual analogue scale (VAS) after 8 h, 24 h, 48 h and 7 d. In addition, the time intervals to medication intake were recorded. The collected data were statistically analysed using the chi-square and Mann–Whitney U test (p<0.05).Results: The average pain level in the control group 24 h after the first visit was significantly higher than that in the laser group (p<0.05). The average pain level 24 h and 48 h after the second visit was significantly higher in the control group (p<0.05). The levels of PP 24 h after the first visit were higher than those after the second visit only in the control group (p<0.05). After the first visit, analgesic use in the control group was significantly higher after 8 h (40%) and 24 h (23%) as compared with that in the laser group (p<0.05).Conclusions: Root canal irradiation with a diode laser may reduce PP after RCT in single-rooted teeth with a PAI score of 3 or 4.Trial registration: Effect of the Diode Laser on Post-operative Pain After Endodontic Treatment in Teeth with Apical Periodontitis: NCT04486196.

Abstract 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.

Relevanct of the research topic. One of the possible causes of apical periodontitis is the infectious inflammatory process of the periapical periodontal tissues. The microflora of the root canal system is represented by various microorganisms, among which streptococci, enterococci and staphylococci most often prevail. The complex anatomy of the root canal system ensures the growth and reproduction of microorganisms, and the endodontic treatment does not always contribute to their qualitative and quantitative reduction. Purpose ― study of the effectiveness of endodontic treatment of chronic apical periodontitis in the near and long term. Methods. We observed 110 patients aged 20 to 30 years with apical periodontitis, bone density analysis and microbiological examination of the contents of the root canal. Depending on the obtained clinical and laboratory data, the patients were divided into two clinical groups: in group I endodontic treatment of 55 teeth was carried out according to the scheme developed by us; in group II — 55 teeth using the standard method of treatment. Results. In endodontic treatment of chronic apical periodontitis, treatment of the root canal system with a diode laser promotes better decontamination of the microflora. Coal mining introduction into the root canal system and in the region of the transition folds of the platelet autoplasma leads to an increase of the reparative process in the periapical region (p≤0.05). Summary. The inclusion in the Protocol of endodontic treatment of apical periodontitis of treatment of the root canal system with a diode laser and injection of platelet autoplasm is a more effective method of treatment in comparison with the traditional one.

Objective. To assess the 6- to 24-month outcome of endodontic treatments performed, by one specialist, and to identify prognostic factors that may influence initial endodontic treatment outcome (IETO).Methods. One hundred and forty-six patients out of 163 were included. A number of 201 teeth were endodontically treated, and an overall number of 408 canals were obturated. Of these, 165 teeth received initial endodontic treatment (IET). The criteria of the European Society of Endodontology were used to assess the IETO. The level of significance was set atp<0.05%.Results. Apical periodontitis (AP) was present in 42.5% of all cases, with a PAI >3 in 28.5%. The success rate (SR) was 91.5%. It was significantly higher in vital teeth (97%) than in devital teeth (87.7%) (p=0.04); however, a lower SR was recorded in teeth with AP (p=0.02). The lesion healed in 60 teeth (85.7%), decreased in size in 4 teeth (5.7%), and increased in size in 6 teeth (8.5%). A higher SR was obtained when a permanent restoration was present (94%) than absent (68.7%) (p=0.005).Conclusion. Within the limitations of the study, pulp and periapical status and permanent restoration are found to be strong outcome predictors.

Introduction: Photodynamic therapy (PDT) has emerged as a powerful tool for conventional endodontic treatment, capable of eradicating microorganisms present in endodontic infections. Despite this, the use of PDT in the surgical endodontic treatment is not well-known. Case Report: This paper describes the case of a patient with asymptomatic apical periodontitis in a mandibular incisor submitted to surgical endodontic treatment associated with PDT. After conventional procedures, photosensitizer methylene blue (0.01%) was applied to the retrograde cavity for 3 minutes, followed by irradiation with diode laser (100 mW and 660 nm) for 3 minutes. Six months after the procedure, the patient was asymptomatic, and the radiographic examination showed healthy periradicular tissues. Conclusion: The association of PDT with surgical endodontic treatment was effective, suggesting that this therapy may provide additional benefits to patients when compared to the conventional surgical technique.

Objective. The objective of this retrospective study is double: (1) to assess the 1–4 years of outcome of endodontic treatment performed by postgraduate students in endodontics in the Dental Clinic of Bretonneau Hospital and (2) to examine outcome predictors.Method. 363 teeth in 296 patients were treated between 2007 and 2011. 183 patients (224 teeth) were lost during the followup. 113 patients were included in the study (recall: 38%), corresponding to 139 teeth of which 8 were extracted. 131 remaining teeth (36%) were examined clinically and radiographically. Apical periodontitis (AP) was absent (PAI = 1) or present (PAI ≥ 2). Outcome was classified as “healed,” “healing,” or “diseased”.Results. The success rate was 92%. No failure was observed among the 23 initial endodontic treatments. Among the 108 retreated teeth, 80% were “healed” and 11% were “healing.” An association was found between success rate and preoperative signs or symptoms (absent 95% versus present 83%), preoperative root filling density (inadequate 93% versus adequate 57%), but not between preoperative AP status and success.Conclusion. Outcomes in this retrospective study were similar to those previously reported. However, a larger sample size is needed to assess outcome predictors more precisely.
