The main goal of endodontic treatment is an effective cleaning and shaping of the root canal in order to eliminate bacteria from the canal system and prevent the occurrence of apical periodontitis. Adequate choice of instruments and preparation techniques significantly reduce the number of bacteria in the canal system prior to obturation. Studies have confirmed that canals instrumented to acceptable apical diameters provide significantly lower number of bacteria even without the use of irrigation. Application of rotary instruments, such as BioRaCe, provides biologi- cally appropriate diameter in the apical portion of the canal and thus a lower number of residual bacteria to ensure safe and effective obturation.

Introduction The main purpose of endodontic treatment is to clean the root canal system, eliminate the infected and toxic contents, and shape it in order to get a tridimensional obturation. The aim of this paper is to inform dental practitioners about crown-down techniques for root canal preparation using nickel-titanium rotary instruments. Root canal preparation Today most endodontists believe that root canal preparation is more officious, cleaning and shaping are better, if pre-enlargement of coronal two thirds is performed first, and shaping of the apical part later. Machine driven rotary instruments provide much quicker and better root canal preparation. Conclusion Contemporary endodontic rotary files vary in regard to their taper, cutting blades, guiding tip and material they are made of. The usage of rotary nickel-titanium files adds a new quality to root canal preparation.

ABSTRACT Aim C-shaped canal system is a seldom-found root canal anatomy which displays a challenge in all stages of endodontic treatment. According to the literature, this type of canal morphology is not a common finding in the mandibular first molar teeth. Background This case report presents endodontic management of a mandibular first molar with a C-shaped canal system. Case report Root canal system was cleaned and shaped by nickel-titanium (NiTi) rotary instruments combined with selfadjusting file (SAF). Obturation was performed using warm, vertical condensation combined with the injection of warm gutta-percha. Follow-up examination 12 months later showed that the tooth was asymptomatic. The radiological findings presented no signs of periapical pathology. Clinical significance The clinician must be aware of the occurence and complexity of C-shaped canals in mandibular first molar teeth to perform a successful root canal treatment. The supplementary use of SAF after application of rotary instruments in C-shaped root canals might be a promising approach in endodontic treatment of this type of canal morphology.

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.

Apical Leakage

Hermetical obturation on dentine-cement junction is one of the conditions for success in endodontic treatment. The aim of this paper was to evaluate apical obturation of three different root canal obturation materials. Methods consisted of in vitro semiquantitatively measured penetration of colored solutions. Total number of 55 single-canal teeth was used and obturation test materials were AH-plus, Ketac-Endo and Endomethasone. Linear color penetration was evaluated following illumination of teeth in 2% sol. Metylsalicilate. Results obtained have shown better adhesion between sealer and root canal walls, i.e. better apical obturation when AH-plus (0.25mm) and Ketac-Endo (0.52mm) were used and highest rate of apical leakage when Endomethasone was used (2.35mm). None of the tested obturation materials have sealed apical portion completely.

Objective: The aim of this study was evaluate radiographically prevalence of apical periodontitis (AP) in endodontically treated teeth (ETT) and relate with demographic factors, quality of endodontic treatment and coronal restoration. Material and methods: Data were collected from dental records wich contained full-mouth radiographic series. In ETT, arch, dental group and presence of AP were evaluated. Quality of root canal filling, presence and quality of coronal restoration and type of restorative material were also collected. Data were evaluated using descriptive statistics and Chi-square Test. Results: Of 70 patients included in the final sample, the majority were female (54.3%) and age ranged from 13 to 77 years (47.14 ± 13.18). Of 1,333 teeth evaluated, 73 (5.4%) had endodontic treatment, being the majority maxillary (74%) and anterior teeth (52.1%). Of teeth without endodontic treatment, 320 (25.4%) had AP. Failure rate was high (52.8%) and quality of root canal filling and coronal restoration were considered inadequate in majority cases (58.3% and 47.7%, respectively). Dental group had a statistically significant relationship with presence of AP in ETT, being more frequent in anterior teeth (p = 0.019). Conclusion: It was concluded that prevalence of AP in ETT was high and dental group was the factor that most influenced prevalence of AP in ETT.KeywordsApical periodontitis; Radiography; Root canal filling.

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.
