Filter by:This clinical study aimed to Compare the levels of Interleukin 8 before and after root canal treatment in patients with apical periodontitis - Diagnosis - Local anesthesia - Isolation and disinfection of the tooth - Two-staged access cavity preparation - Patency of the root canals - First sample collection using paper points - Working length determination - Chemico-mechanical preparation - After 1 week, isolation, Second sample collection then obturation of the root canals and restoration of the tooth. - Samples will be stored in (-80 C) freezer till collection of all samples then, quantification will be done using ELISA.
The goal of this clinical trial is to evaluate the effect of cold saline (2.5 degrees Celsius) irrigation on postoperative pain in patients who require root canal treatment in molar teeth because of dead dental pulp and infection around the apex of the root of the involved teeth. This cold saline irrigation will be done after standard irrigation of the canal using a 5.25% sodium hypochlorite solution. The main questions it aims to answer are: - Is there any difference in postoperative pain when final irrigation is performed using a cold saline solution compared to the irrigation using the saline solution at room temperature in patients who require dental root canal treatment of molar teeth? - Because of cold saline irrigation, what type of adverse event/s may result? Participants will be asked to fill out a questionnaire before the start of the root canal treatment and record the preoperative pain using the visual analog scale (VAS). Root canal treatment will be completed in one visit. The standard procedure of root canal treatment will be followed, including irrigation of the canal using 5.25% sodium hypochlorite. As a final irrigation, either cold saline solution or a normal saline solution at room temperature will be used. The participants will be asked to fill out another questionnaire and record the presence, duration, and intensity of postoperative pain, and if painkiller medicine was taken immediately after completion of root canal treatment and at 6 hours, 12 hours, 72 hours, and 1-week intervals. The researcher will compare the effect of the final irrigation of a cold saline solution with that of a normal saline solution at room temperature on postoperative pain.
the aim of this study is to compare the effect of using Diclofenac Sodium Versus Calcium Hydroxide as Intracanal medication on intensity of postoperative pain, bacterial load reduction after root canal preparation and periapical matrix metalloproteinase 9 level (MMP-9) post-instrumentation and pre-obturation in teeth with necrotic pulp
Regenerative endodontic procedures have been used to successfully treat human mature permanent teeth with necrotic pulps and apical periodontitis. Many researchers have begun to apply regenerative endodontic procedures to mature teeth in adult patients. Several clinical case reports have shown complete resolution of signs and symptoms of pulp necrosis in mature teeth, even those with large periapical lesions, as well as signs of pulp canal obliteration. The aim of this study is to assess the regenerative potential of mature permanent teethwith necrotic pulps after disinfecting the root canal using diode laser andcompare it with dynamic agitation of xp-endo finisher and conventionaltriple antibiotic paste
The aim of the present study is to show that the use of 0.55T MRI combined with a "dental" coil produces images of sufficient diagnostic value to assess areas of interest in dentistry, and to compare MR images to traditional, dental-oriented radiographic images for diagnostic purposes.
This study evaluates the effect of leucocyte and platelet rich fibrin Block (L-PRF Block) during endodontic microsurgery (EMS) on patient's post-operative comfort and periapical bone healing in large peri-apical lesions.
Inflammatory process begins around root apex as a result of bacterial infection of pulp cavity in chronic apical periodontitis. Bone destruction can begin in apical region after immunological reactions at the end of inflammatory process, and radiolucent periapical lesion seems in this way. If bone destruction around apical region is in the rate of 30%, we can notice this difference eventually. Histological manifestations of periapical inflammation can be observed in the result of pulp necrosis and inflammation around apical region. Mocelular methods can determine the type of therapy in various diseases. Each region and tissue reserve specific host factors. Vast majority of pulpal inflammation was trigerred by microorganisms. Certain bacterial virulence factors may damage host tissue directly, other virulence factors can stimulate prolonged non-specific immune response causing tissue damage. In the last phase of infection, immunopathological destruction of pulp tissue is observed due to humoral response. IL-17 is an important inflammatory cytokine released from T cells of the immune system. TNF-alpha and RANKL are also mediators responsible for bone destruction metabolism. TNF is a cytokine mediating immunologic changes during periodontal disease. TNF induction stimulate secondary mediators taking part as chemotactic cytokines. TNF has two different types; TNF-alpha and TNF-beta. TNF-alpha is a polypeptide cytokine produced by macrophages and monocytes. TNF-alpha stimulates bone resorption . There has been limited researches analyzing GCF, blood and tissue of pulp, dentin-derived fluid and periapical fluid for molecular diagnosis so far. GCF is a fluid derived from gingival groove. This fluid contains a lot of host factors such as anticor, bacterial antigen, protein and cytokines. GCF sampling is a non-invasive method, it can be used to provide diagnostic information in all clinical cases. In this study, we will evaluate the levels of IL-17, TNF-alpha and RANKL in the gingival crevicular fluid of teeth with periapical lesion diagnosed with chronic apical periodontitis. Thus, it will be evaluated whether these markers can be used for diagnosis and follow-up of the disease in teeth with periapical lesions.
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.
Aim: The aim of this study was to examine post-operative pain (PP) severity after conventional irrigation and sonic activation methods, with and without laser disinfection in mandibular molar teeth diagnosed with symptomatic apical periodontitis. Methods: In total, 80 patients with symptomatic apical periodontitis were included in this randomized clinical study. There were four different irrigation and disinfection groups. In group 1, conventional irrigation only was applied. In group 2, EDDY (VDW, Munich, Germany), a sonic irrigation activation system, was applied. In groups 3 and 4, irradiation with a 980-nm diode laser was performed, following irrigation with the conventional method (needle irrigation) and EDDY (VDW) irrigation system, respectively. PP was assessed using a visual analogue scale (VAS). The patients were instructed to record their PP using this scale 8, 24, 48 hours and 7 days post-procedure, in addition to their analgesic intake. A chi-square test, Fisher's exact chi-square test and Fisher-Freeman-Halton exact test were used to assess qualitative data. Inter-group and intra-group parameters were assessed using the Kruskal-Wallis test and Wilcoxon's test at a significance level of p < 0.05 (for both).
To evaluate the effect of primary non-surgical endodontic therapy on glycaemic control in type 2 diabetic patients with asymptomatic apical periodontitis.After fulfilling the eligibility criteria, patients will be informed about the study and written consent to participate in the study will be acquired from each patient after explaining risks, benefits and alternative treatments.The endodontic treatment for all patients will be performed by a single operator (S.A) following a standardized protocol. The control group will receive no endodontic treatment during the study period. After completion of the study, these patients will be given primary non-surgical endodontic treatment. The patients in control group will be rendered the necessary treatment, if they become symptomatic and/or deny the consent during the course of the study. These patients will be excluded from the study.
