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.

Introduction: to determine the frequency of fenestration and dehiscence bone defects present in maxillary teeth with apical periodontitis, mainly in teeth with endodontic treatment, as they are frequently cause of nonspecific symptoms after treatment. Methods: 1201 Maxillary Cone Beam Computed Tomography (CBCT) exams were analyzed and 803 teeth with apical periodontitis were selected. Results: of the teeth with apical periodontitis, 142 had a fenestration defect (18%) of which 105 teeth (74%) were endodontically treated. The highest frequency was observed in premolars, with no statistical differences between groups. Dehiscence defect was found in 139 teeth (17%) out of which 90 (65%) were endodontically treated. The highest frequency was observed in molars, with statistical differences in relation to other tooth types (p< 0.001). Conclusion: an important number of teeth with apical periodontitis present dehiscence or fenestration bone defects, especially in teeth with root canal treatment.

Diabetes mellitus (DM) is a chronic systemic disease that affects the immunoinflammatory response, leading the patient more susceptible to the development of oral diseases, such as apical periodontitis (AP). Thus, this study aimed to clinically and radiographically analyze the periapical status and prevalence of AP in diabetic patients compared to healthy patients. A total of 100 patients were selected and divided into two groups (n = 50): diabetic group - patients with type 2 DM, and control group - systemically healthy patients. Periapical status was analyzed by the periapical index. The quality of the root canal filling and restoration was also evaluated. Difference between the prevalence of AP among the groups were performed by using the Chi-square test or Fisher's exact test (p < 0.05). The total number of teeth was lower in diabetic group (p = 0.049). Teeth without previous endodontic treatment with AP were higher in diabetic group (p = 0.006). However, the number of endodontically treated teeth with AP was greater in the control group (p = 0.027). AP in teeth with previous endodontic treatment was associated with unsatisfactory root canal filling and restoration quality (p < 0.01). The presence of pain showed significantly higher values in the diabetic group (p = 0.003). In conclusion, this study showed an association between the presence of AP and DM in cases of teeth without endodontic treatment. Besides, the presence of pain was significantly higher in diabetic patients. However, healthy patients showed more cases of AP in endodontically treated teeth.

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.

Background: Many challenges encounter the endodontist, especially when dealing with necrotic teeth with chronic periapical lesions. Postoperative pain may be induced following conventional endodontic therapy and total eradication of the bacteria is almost unachievable even with recently available techniques. In recent years, diode laser usage in the endodontic field has gained acceptance. Thus, this study aimed to investigate the ability of the diode laser (DL) to decrease postoperative pain and achieve root canal sterility. Methods: 56 patients with anterior teeth with chronic periapical lesions in upper anterior teeth were randomly divided into two groups (n = 28). All patients were treated with two visits of conventional root canal treatment with ProTaper Universal. The DL group: root canals were irradiated with 200 µm fiber optic at both visits; the control group (Endo): the DL fiber was placed in root canal with no activation. Bacterial samples were collected from all the cases at each step of the treatment. Pain levels were evaluated using a numerical rating scale preoperatively, and after 6, 12, 24, 48 hours and 7 days. Bacterial count was used to detect both aerobic and anaerobic bacterial load.  Results: The qualitative pain scores revealed statistically significant lower pain levels in the DL group compared with the Endo group at all time intervals (P<0.001), except preoperatively where there was no significant difference. There was a statistically significant lower bacterial count for both aerobic and anaerobic bacteria in the DL group compared with the Endo group in both S3 samples (after laser application) and S4 samples (bacterial colonization) (P<0.001). Conclusion: The 980 nm diode laser may be a successful adjunct to conventional endodontic treatment of necrotic cases with chronic periapical lesions in terms of postoperative pain and root canal disinfection.   Trail registration: PACTR201511001275414 (date: 23rd September 2015)

Subject. A sufficiently sensitive, high-resolution method of laser doppler flowmetry is used to characterize the сlaudication in the oral mucous membrane and periodontal tissues. This method makes it possible to detect early changes in the microcirculatory bloodstream and predict the course of chronic apical periodontitis. With the help of the method of laser doppler fluorometry, a comparative monitoring of the microcirculatory bloodstream of the mucous membrane of the transitory fold in the area of intact teeth and teeth with chronic apical periodontal was carried out. The aim of this study was efficiency determination of complex endodontic treatment of chronic apical periodontitis on the basis of monitoring the state of microcirculation of the mucous membrane in the transitory fold of the studied teeth. Methodology. Control group consisted of 55 patients with chronic apical periodontitis, and 20 patients with intact teeth aged 20 to 30 years old who underwent the analysis of microcirculation of the mucous membrane of the transitional fold of the studied teeth using laser doppler flowmetry (LDF). Results. The indicators IM, Kv, Q among 20 patients with intact teeth examined with the method of laser doppler flowmetry (LDF) were taken as normal. Studied parameters are significantly lower than normal in 55 patients with chronic apical periodontitis. In case of patients with chronic apical periodontitis, the inclusion of complex composed of the root canal system treatment by diode laser and the insertion into the root canal trombocytic autoplasma and its injection in projection of the root end in the protocol of endodontic treatment of chronic apical periodontitis helps to normalize microcirculation in the mucosa of the transitory folds of the investigated teeth. Summary. The study of the dynamics of the complex of endodontic treatment of chronic apical periodontitis showed its high efficiency (p≤0.001).
