View clinical trials related to Periapical Periodontitis.
Filter by:A total of 185 subjects were divided into three categories: AP group (n=85), CP group (n=50) and healthy control group (n=50). The AP group was divided into 3 subgroups according to abscess scoring (AS-PAI) based on the periapical index. The CP group was divided into 4 subgroups according to the periodontitis staging system (PSS). After recording the demographic and clinical characteristics of all participants, blood and gingival crevicular fluid (GCF) samples were taken. TNF-α, IL-10, PGE2 and NO levels were measured in these samples.
Aim: Apical periodontitis(AP) caused by root canal infection is the most frequent pathological lesion in the jaws. Bacterial products, host immune cells and biologically active factors called locally produced cytokines(such as IL-1, TNF-α) have been reported to play an important role in the pathogenesis of AP. Metalloproteinases(MMP), is a measurable biomarker that plays an important role in the degradation and regeneration of collagen and is an indicator of collagen. This study aimed to determine the main bacterial species in the microbiota as Gr(+) and Gr(-) and to compare the relationship between MMP-9 and TNF-α with controlled patient groups. Methodology:60 patients with AP and extraction indication were included in the study. 30 systemically and orally healthy volunteers were selected as the control group. After access cavity preparation, an initial microbiologic sample(S1) was taken from the root canal. After atraumatic extraction of the tooth, second microbial sample(S2) was taken from the external root surface. After bacterial DNA extraction, 16S rRNA gene primer was designed for sequence analysis. Bacterial community profiling was made by Sanger sequencing of the PCR products. Besides, blood samples were collected from all of the patients. Enzyme-linked immunosorbent assay was used to measure levels of MMP-9 and TNF-α.
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.
Type of study: Randomised Clinical trial To compare the effectiveness of Mechanical and Chemomechanical methods in the removal of Water-based Calcium hydroxide medicament from endodontic system. Participants allocated in group A and B should be appointed for Endodontic treatment of Single rooted teeth diagnosed with Necrotic Pulp and Chronic Apical Periodontitis. In group A, Calcium hydroxide medicament will be removed by using Mechanical method while in group B, Calcium hydroxide will be removed by using Chemomechanical method.
Following the randomization procedure, patients will be divided into 2 groups (12 immature molars in each group): Group I will be treated with MTA as apical plug, whereas group II will be treated with Biodentine as apical plug. After working length determination, instrumentation and sterilizing root canals, apical plug will be done as following: Biodentine Group: Biodentine will be placed into the apical portion of canals. After 12 min the coronal and middle third of the root canal will be filled with gutta-percha and AH Plus. The coronal restoration will be completed with GIC, composite, and stainless-steel crown. MTA Group: MTA will be placed into the apical portion of canals, then a moist cotton pellet will be placed and the access cavity will be restored with temporary filling. Next day, temporary filling and the cotton pellet will be removed, then the coronal restoration will be performed as Biodentine group. Patients of both groups will be recalled for clinical and radiographical follow-up within 12 months after treatment.
Aim of the present study was to determine the intraradicular microbiota of previously root canal-treated teeth with apical periodontitis using droplet digital polymerase chain reaction (ddPCR) and to investigate the antibacterial effectiveness of different irrigation activation methods [ Sweeps laser and PUI group ] that will make classical chemomechanical preparation more effective. This superiority, parallel, randomized clinical trial was conducted in the clinic of the Endodontic Department, Faculty of Dentistry, Istanbul Medipol University, Istanbul. 30 patients with apical periodontitis (one tooth each) were randomly allocated into two groups according to the used (n=15, for each): the Sweeps laser group (A) or the vdw ultra group (B). Total bacterial loads, as well as the amount of Enterococcus faecalis (E.faecalis) were determined before (S1) and after (S2) chemomechanical preparation and finally, after intracanal medication (S3) by means of ddPCR.
