Filter by:Aim: Evaluation of the effect of different obturation techniques on postoperative pain level and radiographic healing on non-surgical endodontic retreatment (NSER) applied in a single visit in teeth with single root canal and apical periodontitis (AP). Materials and Methods: 63 teeth with single-root canal and AP from 50 systemically healthy patients (mean age 34.19±9.75 years; 27 women, 23 men) were included in the study. Residual root canal filling materials were removed with retreatment files. All teeth were prepared using rotary files . The teeth were randomly divided into three groups according to the obturation technique; cold lateral compaction (CLC), continuous wave compaction (CWC), and gutta-core (TGC). Restorations are completed using direct composite resin in the same visit. In all cases, pain status were evaluated using the Numerical Pain Rating Scale (NRS) at preoperative, postoperative, 3rd hour, 24th hour, 48th hour, and 7th day. Periapical index (PAI) scores were recorded on preoperative and postoperative 6-month on the periapical radiographs for cases. Data were analyzed as statistically. Significance level was determined as p < 0.05.
The aim of this study is to evaluate in vivo the post operative pain after laser root canal treatment in necrotic teeth in an evidence-based clinical trial. The null hypothesis being tested is that there is no difference in post operative pain between conventional irrigation and the two types of lasers used. Thirty patients are equally divided into 3 separate groups : - Group A (Conventional): 2.5% NaOCL and 17% EDTA. - Group B(Dual): saline along with Er,Cr:YSGG laser and diode laser combination - Group C(Combined): saline along with 17% EDTA and diode laser combination Each patient is given pain scale chart Numeric Rating Scale (NRS) to record his/her pain level before any endodontic treatment. All data will be collected, tabulated, summarized, and statistically analyzed.
The goal of this observational is study is to develop a protocol for root canal biofilms disinfection using a clinically approved and commercially available iron oxide nanoparticle formulation Ferumoxytol/H2O2 treatments. This protocol will be testing local single topical application of Ferumoxytol within the root canal system in patients going through routine root canal treatment, evaluate its potential as anti-biofilm treatment and compare it to the clinical gold standard disinfecting solution sodium hypochlorite (positive control) and saline (negative control).
The aim of this study was to evaluate the effect of continuous rotation and reciprocation kinematics on post operative pain and difference in substance P levels in patients with irreversible pulpitis with symptomatic apical periodontitis. Twenty patients were randomly distributed into two groups; Continuous Rotation group(n=10): received mechanical preparation using EdgeEndo x7 rotary system (Albuquerque, New Mexico, USA), while Reciprocation group(n=10): received mechanical preparation using EdgeOne Fire reciprocating system (Albuquerque, New Mexico, USA). Apical fluid(AF) samples were collected, and substance P (SP) levels were measured using radioimmunoassay and postoperative pain was measured using Numerical Rating Scale (NRS) preoperatively, at 6h, 12h, 24h, 48h and 72h.
This study aimed to link lifestyle factors (Mediterranean diet adherence, stress, sleep quality, physical activity) to caries and apical periodontitis in 149 university-based individuals. Data included clinical and radiographic assessments and lifestyle questionnaires. Statistical tests and logistic regression were employed to analyze the relationships between these factors and oral health conditions.
Goal of this prospective observational study is determine effect of smoking on periapical healing after NSRCT. Population includes systemically healthy smokers with radiographic evidence of apical periodontitis will be recruited and compared with same type of population of non smokers after non surgical root canal treatment intervention in both the groups. Outcome will be assessed using periapical index scoring system at 6 and 12 months follow up period
The aim of the study is to evaluate the association between apical periodontitis (AP) and atherosclerotic cardiovascular disease (ASCVD) by assessing the multiplicative effect of AP on secondary outcomes of ASCVD. Sixty-two subjects will be enrolled from the Unit of Endodontics and Restorative dentistry and allocated into 2 distinct groups depending on the presence or absence of periapical lesions. Group 1 will be composed of 31 patients with radiographic signs of AP. On the contrary, another 31 healthy individual (free from clinical and radiographic evidence of AP) meeting the inclusion and exclusion criteria were included as controls (group 2) A complete dental examination will performed on each patient in both groups. All the patients will be subjected to a cardiovascular examination to assess carotid intima-media thickness (cIMT), presence of abdominal aortic aneurysm, presence of peripheral pulses through echo-color-doppler.
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 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.
