Filter by: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.
This study aims to assess the hypothesis that revitalization of teeth without (a)symptomatic apical periodontitis have a more favourable outcome in terms of further root development, periapical bone healing, maintaining/regaining pulp sensitivity and survival, than teeth with (a)symptomatic apical periodontitis.
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.
The goal of this clinical trial is to compare the effectiveness of various root canal cleaning devices based on the principle of cavitation, ultrasonics, and conventional methods in a normal healthy adult population aged between 18 to 75 years requiring root canal treatment. The main question[s] it aims to answer are: - Effectiveness of the cleaning mechanism - Evaluate the safety of use of the device. Participants will be provided root canal treatment. Participants will be asked to record their post-operative pain levels in a Patient Pain diary. The healing rate of the lesion will be examined at follow-up visits using intraoral X-rays. At the end of the study, a statistical analysis of the clinical outcomes of the root canal treatment will be examined and evaluated in every group.
With consideration of the previous studies regarding the properties of i-PRF, it will be used in combination with another bioactive material: (Nano-BAG) versus using of i-PRF only as a pulpotomy material with using a premixed bioceramic putty as a coronal sealing material in both cases, to evaluate if there is a difference in the success rate of pulpotomy in case of using Nano-BAG in combination with i-PRF So, in this study the investigators will use Nano-BAG in combination with i-PRF as a material for pulpotomy in cases of mature permanent mandibular molars and compare its outcomes with using i-PRF only and in both cases pulpotomy material will be covered with a layer of premixed bioceramic putty for coronal sealing.
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.
The aim of this study is to evaluate the effect of two different periapical surgery methods ("curettage+apical resection" and "curettage") on the bone regeneration and clinical healing without applying any material or with applying leukocyte and platelet rich fibrin (L-PRF) to the periradicular intraosseous defect in the treatment of the teeth with large periapical lesions by following the patients for 12 months.
While cross-sectional studies have reported a significant association between diabetes and Apical Periodontics, prospective studies are scarce. This will be the first prospective interventional study to explore the cause-and-effect relation between AP and diabetes by assessment of levels of inflammatory markers in a longitudinal setting. Periapical healing in diabetics and nondiabetics will be compared after root canal treatment to evaluate the role of various physical and metabolic attributes on endodontic outcomes.
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
