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.

Pulp debridement and disinfection in the pulp cavity is a critical step in achieving a successful root canal therapy. Microorganisms remaining in the root canal system after endodontic treatment are a main cause of root canal failure. The challenges faced in endodontic disinfection include the complex anatomy of the root canal system, the existence of a biofilm within the root canal, and the creation of a problematic smear layer during instrumentation of the canal. Historically, sodium hypochlorite and ethylenediaminetetraacetic acid have been utilized as irrigants and still remain as the most effective disinfectants due to their synergistic abilities to eradicate microorganisms, dissolve necrotic debris, and remove the smear layer and biofilm. This article addresses challenges in endodontic disinfection, objectives of endodontic irrigants, properties of an ideal irrigant, currently used irrigants, and irrigant delivery systems utilized in veterinary dentistry.

ABSTRACT Aim To evaluate the interference of the intracanal medication Calen® (SSWhite, São Paulo, Brazil) on the filling of simulated lateral canals. Materials and methods Twenty human anterior teeth were used. Before the endodontic filling procedures the access of cavity was made, and after this root canals were made in all the teeth to simulate the presence of lateral canals. After preparation, the teeth were randomly divided into two groups (n=10). In group I, the root canal system was filled directly after chemicalmechanical preparation; in group II, endodontic treatment was performed in multiple sessions, and after preparation the calcium hydroxide-based intracanal medication Calen® was inserted. After the period of 7 days, the root canals were vigorously irrigated and then they were filled. Next, the teeth were radiographed to verify the quality of the filling. Results The results demonstrated that the teeth treated in a single session, without calcium hydroxide medication, presented 47 canals out of 60 with radiographic evidence of filling, whereas the teeth in which intracanal medication was used, only 07 presented a radiographic image compatible with filling (p < 0.05). Conclusion The use of the calcium hydroxide-based medication Calen made it difficult to obtain a hermetic filling of the root canal system. Clinical significance The clinical significance of this work basing on the fact that once the dentist knowing that property obliteration of calcium hydroxide can be taken care when they are used in the presence of lateral canals.

BACKGROUND Various intracanal medicaments have been used in cases of chronic apical periodontitis for appropriate disinfection of the root canal system to eliminate microbes specially from the inaccessible areas. Caclcium Hydroxide (CH) is the most common intracanal medicament available in various forms, but its effectiveness with or without iodoform using microbial culture is unknown. OBJECTIVE To compare the anti-microbial efficacy of Calcipex and Metapex in endodontic treatment of teeth presenting with chronic apical periodontitis METHODS 60 single rooted teeth of patients with diagnosis of chronic apical periodontitis were selected and the canals were debrided chemo-mechanically. The patients were randomized into two groups: Calcipex and Metapex. The first sample (S1) for bacterial culture was taken before placement of intracanal medicament and the second sample (S2) was taken after 7 days, before final obturation from the canal and sent to lab for culture. Colony Forming Unit (CFU) will be evaluated. Paired t-test will be used to assess difference bet¬ween antimicrobial efficacies within the group of medicaments. Independent sample t-test will be used to assess antimicrobial efficacies between groups. Level of significance will be kept at 0.05. RESULTS The results wil be shared upon completion of study. CONCLUSIONS There is no risk involved in this study as the study is based on routine procedure of endodontic treatment. It will be a benefit for future patients which will help us to decide which intracanal medicament is more effective to use in infected canals. CLINICALTRIAL NCT04336709

Root Canal System

The primary objective of endodontic therapy is to create a biologically acceptable environment within the root canal system that allows for the healing and maintenance of the health of the peri-radicular tissue. Bacteria are one of the main causes of pulp problems, and they have different methods of penetrating and invading the endodontic space such as through carious lesions, traumatic pulp exposures, and fractures. The types of bacteria found range from facultative anaerobes to aerobes, up to the most resistant species able to survive in nutrient-free environments; the bacterial species Enterococcus faecalis belongs to this last group. Enterococcus faecalis is considered one of the main causes of recurring apical periodontal lesions following endodontic treatment, with persistent lesions occurring even after re-treatment. The review presented in this paper was performed in accordance with the PRISMA protocol and covers articles from the related scientific literature that were sourced from PubMed, Scopus, and Google Scholar using the following terms as keywords: “endodontic treatment”, “endodontic bacteria”, “microbial endodontic”, and “endodontic failure”. Only the articles considered most relevant for the purposes of this paper were read in full and taken into consideration for the following review. The results show that Enterococcus faecalis, Actinomycetes, and Propionibacterium propionicum are the species most frequently involved in persistent radicular and extra-radicular infections.

Insight Into

The aim of this article is to show different anatomic complexities of the root canal system related to maxillary molars. Maxillary molars are presumed to have only three roots with three canals but this is not always the case, it might present with different variations. Some of the anatomical variations such as, mesiobuccal2 (MB2) canals in maxillary 1st and 2nd molars, two rooted maxillary 1st and 2nd molar, one rooted maxillary 2nd molar, C-shaped upper 2nd molar and maxillary 2nd molar with extra palatal root are reported in this case series. Hence, in treating each tooth every dentist must keep foresight that complex anatomy occurs often enough to be considered normal and manage them accordingly.
