Instrument Separation

SummaryInstrument separation during endodontic therapy is a frequent accident with rotary instruments being more likely to separate than manual ones. The treatment of cases with a separated instrument can be either conservative or surgical. A conservative approach involves the following treatment choices: a) bypass of the fragment, b) removal of the fragment, c) instrumentation and obturation coronally to the fragment. Concerning the removal of a separated instrument, a variety of techniques and systems have been developed. Ultrasonics, in combination with the operative microscope constitute the most effective and reliable tools for removing a separated endodontic instrument from a root canal. The likelihood of successful removal depends on: the level of separation (coronal, middle or apical third); location in relation to the root canal curvature; the type of separated instrument; its length; the degree of canal curvature and the tooth type. Several complications may occur during the management of a separated instrument: separation of the ultrasonic tip or file used for bypassing or removing the instrument; further separation of the fragment; perforation; ledge; extrusion of the file into periapical tissues; tooth weakening due to dentin removal, as well as excessive temperature rise in periodontal tissues. Prognosis for a tooth retaining a separated instrument depends on the presence of a periapical lesion, the microbial load of the root canal during the time of separation and the quality of the obturation.

Causes Of Failure

Object. Causes of failure of endodontic treatment and causes of tooth extraction with a diagnosis of chronic apical periodontitis. Purpose ― to analyze the causes of failure of endodontic treatment and the causes of tooth extraction with a diagnosis of chronic apical periodontitis to determine ways to improve the effectiveness of conservative treatment. Methodology. A retrospective analysis of 864 medical records of a dental patient and 532 results of x-ray examinations of patients who underwent tooth extraction was carried out. 198 dentists-therapists of the city of Tyumen and the South of the Tyumen region were interviewed to determine the shortcomings of endodontic treatment. During the survey, doctors expressed their subjective opinion about the main reasons for the failure of therapeutic treatment of teeth with apical periodontitis and the reasons for their subsequent tooth extraction. Results. According to the survey, the failure of conservative treatment is most often associated with non-compliance with treatment protocols and the complexity of the anatomical structure of the root canals, as well as the inability to adequately clean the root canal system. A retrospective analysis of the data related to tooth extraction revealed that the main cause of tooth extraction is chronic apical periodontitis, which accounts for 69 %. The main reason for the removal of teeth diagnosed with chronic apical periodontitis was a significant destruction of the crown. Summary. In the course of this work, we justified the need to improve existing methods of conservative treatment of apical periodontitis. Improvement of endodontic treatment should be aimed at the development and implementation of effective methods of root canal cleaning and irrigation solution activation. In order to improve the prognosis of endodontic treatment and reduce the proportion of tooth extractions for periodontitis, it is necessary to improve the quality of the final restoration and to monitor its tightness.

Instrument Separation

Aim. During endodontic treatment, dentists may face various unwanted procedural accidents, at any stage of the treatment that might compromise endodontic treatment outcome and bring obstacles to dentists as well. This study aimed to address and analyze several ethical concerns relating to the behavioural conduct of dentists towards endodontic instrument separation as well as perforation of the crown and/or root during root canal treatment in Riyadh, Saudi Arabia. Method. Hundred and eleven questionnaires were distributed among dentists working in Riyadh in university clinics and government and private sectors. Data were collected, reviewed, and statistically analyzed by Fisher’s exact and chi-square tests at a 5% significance level, using SPSS software. Results. 54.5% of the respondents have encountered instrument separation. 53.2% stated that they would inform the patient about the instrument separation. 43.6% of the respondents had experienced perforation during root canal treatment, and 54.9% reported that they would inform the patient of the accident. Conclusion. Within the limitation of this survey, we concluded that most of the dental professionals did not hesitate to adhere to the correct ethical conduct, and they would inform the patient if an incident occurred.

Single visit root canal therapies are indicated when no periapical changes are appreciated. The final stage of the root canal treatment deals with the filling of the canal system with a biocompatible material. Obturation comprises a core filling material and a sealer. The study aimed to evaluate the type of sealer used for obturation of posterior teeth treated in a single visit and to correlate the sealer use with factors like tooth, gender and operator qualification. The study was a retrospective analysis. A total of 86,000 case sheets were reviewed and necessary data was extracted. The type of sealer used for the obturation was assessed and tabulated along with details like age, gender and tooth. The data was exported to IBM SPSS Software 20. Frequency distribution tables were created and a Chi-square test was performed to check for the correlation of the type of sealer used with various parameters. A total of 1209 molar cases were treated out of which 34.5% were maxillary first molars. The endodontic sealers that have been reported to be put to use are zinc oxide based, resin-based, calcium hydroxide based, medicated, 3 sealer, 4 sealer & others. Maximum cases (53.5%) were treated with a resin-based sealer. A positive correlation (p-value <0.05) is found between the use of sealer and operator qualification. Within the limitations of the study, a variety of root canal sealers were found to have been used for obturation and a positive correlation between the operator qualification & type of sealer used for obturation of molars in single visit RCTs was found.

Irreversible Pulpitis

Introduction. The algorithm for choosing a method of treatment for permanent teeth with incompletely formed root, described in the study of Shabahang S. (2013), involves the procedure of apexification in cases of irreversible pulpitis and pulp necrosis, and convalescent therapy in cases of diagnosis of recurrent pathological phenomena in the pulp structure. The aim of the study was to conduct a retrospective analysis of the effectiveness of applying mineral trioxide aggregate and calcium-containing agents in order to carry out the apexification procedure according to the data of previous studies. Materials and methods. Relevant publications were searched by Google Scholar search (https://scholar.google.com/), Pubmed databases (https://www.ncbi.nlm.nih.gov/ pubmed /) and ScienceDirect (https://www.sciencedirect.com/). Results. The data available to date are of varying evidence and do not confirm the fact that the mineral trioxide aggregate is more clinically effective than calcium hydroxide for the purpose of apexification in cases of endodontic treatment of incomplete root formation. However, a significant advantage of mineral trioxide aggregate is the possibility of one-stage root canal formation with subsequent permanent obturation of the root canal after complete curing of mineral trioxide aggregate. Conclusion. The reports analyzed are characterized by variability of designs and the use of different approaches to assess the formation of the apical part of the tooth; moreover, most publications do not evaluate the initial level of root formation, which can potentially affect the success of the manipulation. The lower success rate of calcium-containing aids for apexification reported in a number of studies is justified by the prolongation of treatment, during which there is a tendency for patients to miss the check-ups and to drop out of the generated study sample during the relevant monitoring period. In order to formulate appropriate clinical recommendations, it is necessary to ensure that the baseline and treatment outcomes are referenced to a unified system of criteria for interpretation of all quality indicators of apexification achieved.
