Filter by:The aim of this prospective cohort observational study is: (i) to assess the endodontic treatment outcome in a private specialist endodontic office in Slovenia; (ii) to estimate the effect of various pre-, intra- and postoperative factors onto endodontic treatment outcome.
Calcium hydroxide is advocated as an intracanal medication for various purposes, including prevention of post-treatment symptoms. Calcium hydroxide has a pain-controlling effect at different times when compared to non-intracanal medication . Aim: The aim of the study to compare between postoperative pain after using two formulations of calcium hydroxide intracanal medication with and without iodoform .
Endodontic treatment is necessary after certain dental trauma or in the presence of a large carious lesion, associated with signs of irreversible pulpal inflammation. The treatment of apical periodontitis is a real public health issue. The endodontic success rate is between 68 and 85%. Indeed, some studies show that systemic diseases such as diabetes can increase the prevalence and bone loss associated with apical periodontitis. Other studies identify apical periodontitis as a factor that can potentiate symptoms caused by inflammatory diseases such as cardiovascular disease and diabetes by increasing the level of inflammatory cells in the blood. However, since 2014 the European Society of Endodontology has recommended establishing a higher level of evidence to ensure the link that these pathologies may have. For this, it is necessary to assess the criteria that may influence the healing of apical periodontitis. Endodata has been developed by dental surgeons specializing in endodontics. The purpose of this software is to improve the clinical follow-up of patients and to establish a clinical and radiological database. In this context, the creation of a clinical database including data for all root canal treatment is of high interest.
The primary aim of the study is to compare the outcome of one vs two visits endodontics (root canal treatments) performed in general dental practice of infected (necrotic) teeth, one and four years after treatment. Secondary aims are to compare the root filling quality and the frequency of complications for both treatment modalities. A pilot study will identify the shortcomings of the protocol, which will be revised accordingly. A multi-center study in several clinics from five counties throughout Sweden is planned. Consecutive eligible patients (see inclusion and exclusion criteria) with one tooth each will be included. The study sample size calculation was based on a judgement that a minimal worthwhile effect of less than 10% was not clinically relevant. The presumption was that successful outcomes would be of 75% and 65% for the different treatment arms, respectively. Three hundred and fifty six patients per group are thus needed to detect that difference as statistical significant with a power of 80% and an alfa-error of 5%. To compensate for around 30% drop-outs a number of 1000 patients will be recruited. Patients will be randomly enrolled in two arms: one in which the endodontic treatment (root canal treatment) is performed in one visit, and in the other arm in two visits. The allocation sequences for one vs multiple visit endodontics will be computer generated followed by a dark colored envelope concealed allocation. The patients will be contacted by telephone 5-7 days post-operatively, and a control visit at the clinic will be scheduled one month post-operatively to assess complications related to the treatment. A clinical control will be performed at the clinic one and four years after treatment. Intra-oral radiographs will be taken. The radiographs will be examined by two blinded and independent observers. A successful outcome is defined by clinical and radiographic normalcy. The statistical methods selected to analyse the primary outcome will be the Chi square test of 2x2 tables, or Fisher´s exact test when proportions are small and the expected value <5. The calculations will be two-tailed. Results will be considered statistically significant at p<0.05.
This study will compare the outcome of single visit retreatment and multi-visit retreatment in cases of failed root canal treated teeth.
This study will evaluate the effect of PRF (platelet rich fibrin) on the healing of apicomarginal defects. Healing of the defects will be assessed 2 dimensionaly by periapical radiograph and 3 dimensionaly using CBCT.
This study will evaluate the synergistic effect of CHX + H2O2 when used as an irrigant during biomechanical preparation.in root canal treatment on periapical healing and compared with Chlorhexidine( CHX) and Sodium Hypochlorite (NaOCl).
The purpose of this study is to determine whether enlarging the apical foramen causes postoperative pain in maxillary anterior teeth with apical periodontitis.
Chronic inflammation plays a crucial role in the genesis of atherosclerosis and at the same time promotes acute cardiovascular events. Periodontal and pulpal inflammation are two major low grade chronic inflammatory infectious disease of oral cavity. Apical periodontitis is an inflammatory process, most often chronic in nature, of endodontic origin usually occurring at or near apex of the tooth root. The scientific literature has failed to provide the potential connection between endodontic infection and CV risk. Few studies have found the possible association, yet few studies does not suggest any link. The association between chronic inflammatory lesions and endothelial dysfunction can be detected using inflammatory, invasive and non-invasive markers. Inflammatory markers such as hs-CRP and Interleukins are not cost efficient and invasive markers- Angiography and Plethysmography are unethical to use on asymptomatic subjects. Non-invasive markers such as Flow mediated dilatation (FMD) and carotid intima media thickness (c-IMT) are inexpensive, fast and safe. The rationale of our study is to check the possible association between endodontic infection and CVD using non-invasive markers.
In view of the wide variety of mechanized endodontic instrumentation systems, the ideal would be that the choose of this system based on the anatomical characteristics of the canal and the biological precepts. In teeth with lesions, contaminated dentin should be removed. However, in many systems, the manufacturer's approach disregards the fact that in wider root canal, instruments used in the apical third small diameter (less than 0.40 mm) may not touch the walls at the final apical. Therefore, the establishment of the initial apical file (LAI), the first instrument that measures the resistance of the walls in working length, could be a criterion in the choice of which system to use, and how many files work within the root canals after LAI determination. However, there is a lack of studies that demonstrate that LAI determination affects the degree of cleaning achieved, as well as the impact that LAI-based instrumentation may have on microcracks formation, canal transportation, postoperative pain and quality of obturation.In this way, the investigators propose a study in vivo performed, in patients from 8 to 18 years of age, therefore in large root canals. The protocol recommended by the manufacturer will be compared by means of a prospective randomized clinical trial, with the addition of the XP Endo finisher and with the protocol based on the initial apical file evaluating postoperative pain, exacerbation between the sessions, the quality of the obturation and periapical radiolucency repair. Considering that currently performing endodontic treatments using mechanized instruments is taught in undergraduate courses throughout the country, studies of this nature help the execution of a endodontics more critical and effective.
