Filter by:This study evaluates postoperative pain and radiographic healing of asymptomatic posterior teeth with chronic apical periodontitis following root-canal treatment performed using EndoActivator for irrigation activation.
The basic aim of root canal treatment is to reduce the microbial content and prevent further recontamination in the canal. Every tooth has a variable, complex canal anatomy consisting of ramifications, accessory and lateral canals. Instrumentation alone cannot reach all the areas for cleaning.The objectives of this research study is to observe and compare the effect of irrigation with smearOFF , etidronic acid/ hypochlorite and other irrigants on sealer penetration and dentin erosion of root dentin by using scanning electron microscope (SEM) and Energy Dispersive X-Ray Analysis (EDX). Hundred extracted premolar teeth is subjected to root canal instrumentation. The endodontic procedure is done with protaper gold files. Initial irrigation is done by 5% sodium hypochlorite. Samples are divided into five groups. Each group consists of twenty single rooted premolars based on final irrigation regimen. There will be four experimental groups which are as follows (1) 17% EDTA (2) SmearOFF 3) Maleic acid (4) HEBP/NaOCL. Whereas, saline will be the control group. After the preparation and final irrigation of all teeth with experimental irrigants, sterile saline is used to flush all canals and dried using paper points. After final irrigation teeth are further divided into two groups (A) Sealer penetration (B) Dentin erosion. In both the groups standardization of root length, cleaning and shaping procedure are the same. For sealer penetration, obturation is done by warm vertical using AH plus sealer. Samples are incubated at 37º Celsius (°C) and 100% humidity for 7 days. The samples are marked and divided into three horizontal section at 2mm, 5mm and 8mm. Using SEM, measure the maximum depth of sealer penetration on each side that is buccal, lingual, mesial and distal and take the mean for each section of sample. For dentin erosion (B) samples are divided sagitally & buccolingually into two halves. The half containing the most visible part of apical area is taken and than examined using EDX. One-Way ANOVA-test will be used to compare mean values of multiple groups. Tukey's post hoc test will be used to determine the group with significance at P≤0.05. Two observers will evaluate the results using kappa statistics.
This is an observational study that assess the impacts of (a) root canal treatment complexity and (b) clinical training on (1) root canal treatment success and (2) tooth survival, in a United Kingdom Armed Forces cohort.
Preserving primary teeth is essential for many aspects such as the child's growth and development, esthetic, functional, psychological, and dental arch integrity aspects. a randomized blinded controlled clinical trial aimed to evaluate the clinical and radiographic success of Zinc Oxide-Ozonated Olive Oil as root canal filling materials for primary molars compared to Zinc Oxide-Olive Oil & Zinc Oxide-eugenol. 90 primary molars of 30 children aged between 4-8 years with pulpally involved primary molars, are equally divided into 3 groups which treated with Zinc Oxide-Ozonated Olive Oil , zinc oxide -olive oil and zinc oxide eugenol as obturation materials following pulpectomy procedure. The subjects were followed up clinically and radiographically at 3, 6 and 12 months.
The aim of this study is to evaluate the effect of low-level laser therapy (LLLT) and intracanal cryotherapy applications on postoperative pain in endodontic interventions of primary molar teeth with apical periodontitis. 75 patients were randomly assigned to the control, low-level laser and cryotherapy groups.Root canal treatments were performed in a single session. The pain intensity felt by the patients on the preoperative and postoperative 1st, 3rd, 5th and 7th days were recorded using the Wong Baker visual pain scale. Preoperative and postoperative 7th day percussion sensitivity was recorded using the VAS (visual analog scale) scale. The pain scores of the groups at different times after the procedure were compared. Statistical analysis of the data was performed at the 0.05 significance level.
A hundred previously root canal treated asymptomatic single-rooted teeth with periapical lesions were treated in single versus multiple visit root canal retreatment. Half of the teeth were randomly assigned to the one-visit (OV) group. The other teeth were treated in two visits (TV). All patients were recalled and investigated clinically and radiographically for 24 months.
Nonsurgical root canal retreatment may become essential when the initial endodontic treatment fails because of the persistent intracanal or extracanal infections.The aim of this thesis study is to evaluate the effect of ProTaper Universal Retreatment (PTUR), Reciproc blue and XP-endo Finisher R file systems, which are used in the removal of root canal filling materials during retreatment with different motion kinetics on the release of Substance P, Calcitonin Gene-Related Peptide (CGRP), IL-6 and IL-10 inflammatory mediators in the periapical region
The chief aim of root canal treatment is to reduce the microbial content and prevent further recontamination in the canal. Properly cleaned, shaped and obturated teeth will be having fewer chances of treatment failure. Every tooth has variable, complex canal anatomy consisting of ramifications and lateral canal. The instrumentation alone cannot reach all the areas for cleaning. For proper cleaning and removal of all microorganisms, the canal should be irrigated with any biocompatible, lubricant and antimicrobial agent. An irrigant should have a high compatibility factor, with canals, with obturating material and sealer. It should remove all the superficial barriers from canal tubules and allow sealer penetration, which aids in better adhesion and decreases the chances for recontamination. Objectives: This study aims to compare the effect of experimental endodontic irrigant Sapindus mukorossi with 17% EDTA, on the microleakage, sealer penetration and interaction with sodium hypochlorite. Ninety single-rooted teeth will be allocated into 2 experimental groups and a control group of 30 teeth each. The endodontic procedure will be done with protaper files. The sample in group 1 will be irrigated with 3.0% NaOCl after that by 17% EDTA and the sample in group 2 final irrigation will be given with Ethanolic extract of Sapindus mukorossi. After the preparation and final irrigation of all teeth, sterile saline will be used to flush all canals and dried using paper points. Obturation will be done with lateral condensation by gutta-percha. Teeth will be incubated at 37ºc and 100% humidity for 7 days. Varnish will be applied on the root surface except for apical 3mm. The teeth will be sectioned longitudinally and examined at 2 and 5mm from the root apex. The maximum depth of sealer penetration will be measured using a scanning electron microscope and microleakage will be tested through a dye penetration method under a stereomicroscope. Testing of interaction between irrigant and hypochlorite will be done by placing 1ml irrigant with 1 ml sodium hypochlorite in a round bottom test tube and left for 1 week at 37ºc. An independent observer will look for precipitation formation or color changes
A hundred asymptomatic molar teeth with periapical lesions were treated in single versus multiple visit root canal treatment. Half of the teeth were randomly assigned to the one-visit (OV) group and received an additional final rinse with 2% CHX before obturation. The other teeth were treated in two visits (TV) with calcium hydroxide dressing. All patients were recalled and investigated clinically and radiographically for 48 months
This study was conducted to compare the antibacterial effect and degree of postoperative pain of single rotary and reciprocating file systems during endodontic therapy
