Filter by:The purpose of this randomized controlled clinical trial was to evaluate two dimensionally and 3-dimensionally the effect of resorbable collagen-based bone filling material on periapical healing following endodontic microsurgery (EMS) on endodontic lesions presenting four-wall defect.
Objectives: Evaluation of endodontic treatment success is largely based on radiographical assessment of anatomical and treatment-related parameters of teeth with apical periodontitis (AP). This study aimed to analyse 2-year treatment outcomes of teeth with AP based on radiographical changes, and to evaluate prognostic validity of Periapical and Endodontic Status Scale (PESS). Materials and Methods: 128 patients (176 teeth) were examined by cone-beam computed tomography at baseline and in 24 months after endodontic treatment. Treatment outcome was evaluated using estimates of periapical radiolucencies in size, relation with anatomical structures and location. Strength of associations between these and treatment-related parameters was tested by logistic regression analysis. Predictive validity of PESS was verified by estimating association between treatment risk groups defined at baseline and negative outcome.
Aim: This study aims to assess the effect of root canal disinfection with a 980 µm diode laser following chemomechanical root canal preparation on the severity of pain after root canal treatment (RCT). Materials and Methods: In present study, asymptomatic, single-rooted teeth with periapical index (PAI) score 3 or 4 were included. All patients were treated with two visits of root canal treatment including dressing with calcium hydroxide. Patients were randomly divided into two groups (n: 28). 'Control (no laser)': The final irrigation was performed using 5ml 2.5% NaOCI, followed by 5 ml 17% EDTA and 5 ml distilled water. 'Laser Disinfection (LD)': Root canals were irradiated with 980 µm diode laser after final irrigation at both visits. The pain levels were evaluated using visual analog scale (VAS) after 8, 24, 48 hours and 7 days. In addition, analgesic intake and time intervals were recorded by patients. The collected data were statistically analyzed with the Chi-square and Mann-Whitney U test (p<0.05).
The aim of study was to evaluate the effect of dental operating microscope use on the healing outcome of non surgical endodontic treatment of maxillary molars.
Introduction: Pulpal necrosis may lead to spread of the infection from the pulp to involve the apex of the tooth and surrounding bone which when asymptomatic with periapical radiolucency on radiograph, is called chronic apical periodontitis. In order to eliminate the virulent bacteria and to overcome the inflammation in the root apex, endodontic treatment is the treatment of choice. Bacteria usually survive in the complex anatomy of the root canal system. In order to eliminate the remaining bacteria, various intracanal medicaments have been used widely however, there is controversy over their use and efficacy. Calcium hydroxide (CH) is the most commonly used intracanal medicament between root canal treatment sessions and available in different combinations. Multiple studies have been conducted to evaluate the effect of various types of CH based medicaments but whether CH with iodoform is more effective than CH alone against endodontic pathogens is a matter of controversy. In order to evaluate the true reduction in microbial load from the infected canals, microbial culture is a predictable and convenient tool. Thus, this study aims to evaluate the antimicrobial effectiveness of inter-appointment intracanal medicament with either CH alone (Calcipex) or CH with iodoform (Metapex) for the treatment of infected root canals of teeth diagnosed with chronic apical periodontitis using colony forming unit (CFU). Objective: To compare the anti-microbial efficacy of calcipex and metapex in endodontic treatment of teeth diagnosed with chronic apical periodontitis and to compare two different methods for removal of oil based intracanal medicaments. Method: Approval from ERC is obtained. The selected subjects will be divided in to two study groups using a computer generated randomization list i.e., Group A - Calcipex group (n = 30) and Group B - Metapex group (n = 30). Two samples will be collected from the root canals for evaluation of microbial load after chemomechanical preparation (S1) (before use of intracanal medicament) and after usage of intra canal medicament (S2)(after 7 days). Two techniques will be used for removal of oil based medicaments. Two radiographs will be obtained for each technique, after oil based medicament placement and after medicament removal for evaluation. Data Analysis: Mean and standard deviation of continuous variable will be computed. Frequency distribution and proportion of categorical variables will be determined. Paired t-test will be used to assess difference bet¬ween antimicrobial efficacies within groups of medicaments. Independent sample t-test will be used to assess antimicrobial efficacies between groups. Level of significance will be kept at 0.05. Mann whitney U test will be used to evaluate medicament removal between 2 groups and at three canal levels; coronal, middle and apical.
the study was to evaluate the effect of intra-canal cryotherapy on post-endodontic pain and interleukin-6 expression in teeth with symptomatic apical periodontitis using different irrigation protocols.
PUFA Index was introduced to detect the clinical consequences of untreated dental caries. To date, there are no studies on the reliability and accuracy of the PUFA index as a screening tool. Other than indices, radiographs were sometimes used as a screening tool using the validated Periapical Index (PAI). The aim of this study was to evaluate the reliability and accuracy of PUFA and PAI in screening for clinical outcomes of untreated caries, specifically pulpal and periapical diseases. The reference standard is the clinical diagnosis, as categorized by the American Association of Endodontists. Intra- and inter-examiner reliability will be determined using Cohen's kappa. Sensitivity, specificity, positive predictive value, and negative predictive value will be calculated. Receiver Operating Characteristics (ROC) contrast estimation will be computed to compare the two index tests.
The purpose is to investigate influence of bioceramic filling of the root canal and photodynamic therapy on periapical healing and development of postoperative pain after endodontic retreatment. Patients are divided into two main groups and each of the group is divided into two subgroups. Main groups are patients receiving photodynamic therapy and patients receiving passive ultrasonic irrigation. Each of the main group is divided by the root canal filling material on the AH+ group and BioRoot group.
The aim of this prospective, randomized, controlled double-blind study is to evaluate the effectiveness of biodentine compared with MTA used as pulp space barrier on discoloration of teeth after regenerative based non-obturation root canal treatment in mature single canal with pulp necrosis and apical periodontitis.
This study evaluates postoperative pain and radiographic healing of asymptomatic posterior teeth with chronic apical periodontitis following root-canal treatment performed using different methods of irrigation activation.
