The objective of this clinical study was to evaluate by polymerase chain reaction (PCR) the antimicrobial efficacy and the outcome of an endodontic protocol treatment (EPT) performed by under-graduated dental students on infected root canals associated with periapical lesions. Fifty-six patients attending for treatment of pulp necrosis and apical periodontitis were included. A specific EPT approach was performed and DNA extracts were taken at the baseline (S1), after a disinfection-neutralization procedure (S2), post-chemomechanical preparation (S3) and after Intracanal medication (S4) for the presence of specific bacteria. The outcome of the EPT was assessed radiographically using the Periapical Index-system (PAI) after 18-month follow-up. An intergroup evaluation shows that when comparing S1 to S3, S1 to S4, S2 to S3, and S2 to S4, the presence of bacteria were significantly reduced (P < 0.05). Finally, S4 was not significantly reduced when compared with S3 (P > 0.05). The most prevalent species in their respect order were Actinomyces Israelii > Enterococcus Faecalis > Fusobacterium Nucleatum/Prevotella Nigrescens > Phorphyromonas Endodontalis. After the 18-month follow-up, the overall success rate of root canal – treated teeth was of 88% (PAI 1 or 2). This In Vivo study demonstrated that EPT significantly reduced the number of cases with positive results for the studied bacteria, showing a profound positive impact in the outcome of endodontic treatment of teeth diagnosed with Pulp Necrosis and Apical Periodontitis.

Abstract The aim of this study was to evaluate the in vivo efficiency of endodontic treatment with calcium hydroxide in chronic apical periodontitis by determining the microbial load from the endodontic space in different stages of treatment. The microbiological determinations that have been made have led to the conclusion that calcium hydroxide possesses a redoubltable antimicrobial activity, but only with the condition of long-lasting contact with the root canals. Another important result is the essential role of the rigorous biomechanical treatment of the root canals, intracanal medication with calcium hydroxide is addresses mostly to microorganisms located in root canal ramifications.

The study aimed to investigate the effects of endodontic space decontamination using a laser combined with ozonated water in the therapy of complicated pulp gangrene. The subject of this in vivo study was a 12-year-old patient diagnosed with extensive periapical periodontitis on the mandibular right first molar. Biological samples were initially collected to identify the active pathogen—Enterococcus faecalis, then the nonsurgical endodontic treatment was performed in a single visit, according to the active disinfection guidelines of the identified pathogen. Two-month postoperative, clinical and radiological examination revealed a complete healing of the periapical lesion. The correct diagnosis of this endodontic–periodontal pathology, and the unconventional treatment of the complex system of infected root canals, allowed a favorable treatment result without any surgical intervention. This unconventional approach, which combines a laser technique with ozonated water, allows for predictable results in periapical lesion treatment.

The number of appointments necessary to treat infected root canals is one of the most controversial issues in endodontics. This study evaluated, in dogs, the response of the periradicular tissues to the endodontic treatment of infected root canals performed in a single visit or in two visits, using different interappointment dressings. Periradicular lesions were induced by inoculating Enterococcus faecalis in the root canals. After confirming that a periradicular lesion developed, the root canals were treated within one or two visits, using either ozonized oil or calcium hydroxide in camphorated paramonochlorophenol (CMCP) as an intracanal medication. After 6 months, the animals were sacrificed and the specimens were processed for histological and histobacteriological analysis. The root canals treated in a single visit showed a success rate of 46%. When a calcium hydroxide/CMCP-based interappointment intracanal medication was used, 74% of the cases were categorized as success. In cases where ozonized oil was used as the intracanal medication, a success rate of 77% was observed. These results of the present study demonstrated that the two-visit treatment offered a higher success rate compared to one-visit therapy. In addition, ozonized oil may potentially be used as an intracanal medication.

Introduction: Enterococcus faecalis is a common bacterial species in resistant and recurrent infections. It has an active proton pump which prevents its easy inhibition leading to endodontic treatment failure. LASER and photodynamic therapy have been employed lately in improving antimicrobial chemotherapy of localized infections. Aim: To compare disinfection efficacy of 940nm Diode LASER & Photodynamic therapy(PDT) to Conventional method using 3% Sodium hypochlorite in canals of endodontically treated primary teeth. Method: Single sitting Pulpectomy was performed on 60 mandibular first primary molars, divided into 3 groups, disinfected using mentioned modalities. Disinfection potential was compared collecting samples at 3 stages using paper points, cultured and incubated for 24hrs to check change in Colony Forming Units of the bacteria. Results: Data analysis with SPSS version 20 software using Kruskal-Wallis and Mann Whitney-U test. Conclusion: The three groups showed effective disinfection as revealed by the reduction in the colony forming units of the bacteria at baseline and after intervention. However, diode laser when used in conjunction with sodium hypochlorite as a disinfecting modality was found to be the most effective for the eradication of Enterococcus faecalis from infected root canals.

The aim of this paper was to, on the basis of everyday clinical practice analize the effect of a homeopathic remedy, as a complementary remedy in endodontic therapy of endoperiodontal lesions and chronic apical periodontitis and to radiologically check its effect on the flow and speed of reparation of damaged periodontal tissues. Endodontic therapy was done according to the usual protocol for the therapy of infectious canals with root canal preparation, medication with calcium hydroxide points and hermetic obturation with AH-26 paste. During endodontic treatment patients were taking homeophatic remedy Hepar sulfuris per os three times daily. The remedy stimulates the natural defences mechanism of the organism. Radiological follow up after three months period showed obvious reductiont of radiologic radiolucency in periapical region.

Aim: Endodontic surgery is a treatment for persistent peri-radicular pathological conditions that do not improve after endodontic treatment. The aim of this study was to evaluate the quality of endodontic treatment, technical error types seen in root canals and the periapical condition of the teeth in patients undergoing periapical surgery, and thus to analyze the reasons leading to periapical surgery. Methodology: Clinical and radiographic data of 301 periapical surgery cases were retrospectively evaluated in this study. The causes of periapical surgery were classified into technical and biological reasons. Results: In this study, 51.8 % of periapical surgery cases were related to biological factors and 48.2 % were related to technical factors. Maxillary anterior teeth were the most common teeth undergoing apical surgery with a rate of 66,8 %.  The most common technical reasons were non-homogeneous filling (15,6 %), underfilling (12,0 %) and overfilling (9,6 %). The most common biological reasons were cysts (30,2 %), traumas (16,6 %) and apical abscess (5,0 %).  37.5% of cases undergoing periapical surgery, the diameter of the cystic lesion was 10mm or more. Conclusion: The number of cases of apical periodontitis is increasing in the community due to insufficiently filled root canals. Increasing the quality of root canal treatments applied by dentists will reduce the need for periapical surgery by reducing the incidence of apical periodontitis.   How to cite this article: Ekici Ö.
