NCT ID: NCT06433375 Active, not recruiting - Periapical Diseases Clinical Trials

Evaluation of the Efficacy of Growth Hormone on Healing of Periapical Pathosis

Start date: April 1, 2023
Phase: N/A
Study type: Interventional

This study aimed to evaluate the effect of growth hormone and non-surgical debulking of periapical tissues on healing of periapical pathosis

NCT ID: NCT05555043 Active, not recruiting - Endodontic Disease Clinical Trials

Comparison of Clinical Outcomes Between GentleWave® and Biolase®

Start date: November 8, 2022
Phase: N/A
Study type: Interventional

Introduction: In the US, 15 million root canal treatments (RCTs) are carried out annually. Success rates decrease with conventional chemo-mechanical root canal preparation techniques used on teeth with periapical radiolucencies associated with bacterial presence. New irrigation modalities, such as the GentleWave® System (GWS) and Waterlase iPlus® (WL), have been developed to overcome limitations and improve RCT success rates. Hypotheses: (1) GWS and WL provide superior clinical outcomes compared to conventional RCT using passive ultrasonic activation (PUI). (2) GWS and WL are acceptable treatment modalities for clinicians and patients. Aims: (1) Estimate probability of success of GWS, WL, and conventional RCT with PUI. (2) Evaluate clinician and patient experiences of the different techniques.

NCT ID: NCT05478811 Active, not recruiting - Periapical Diseases Clinical Trials

Evaluation of RANKL/OPG Levels in Gingival Crevicular Fluid at 1st and 3rd Months of Activation of NaOCl With Er,Cr YSSG Laser in Root Canal Treatment

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

Chronic Apical Periodontitis (CAP) is a disease caused by bacterial infection of the dental pulp and characterized by inflammation of the periradicular tissues. This disease is often the result of untreated caries and accompanied by the destruction of periapical bone and soft tissues, can cause tooth loss. Inflammatory periapical lesion is observed in the radiological examination of teeth diagnosed with Chronic Apical Periodontitis. This periapical lesion manifests as a host defense response to microbial challenge caused by infected pulp necrosis. Polymorphonuclear leukocytes, T and B lymphocytes, macrophages and plasma cells and many inflammatory cells are involved in host defense. These inflammatory cells, especially macrophages, mediate the immunological response seen in chronic apical periodontitis. Diagnosis and evaluation of apical periodontitis are made with conventional periapical radiographs. However, radiographic evaluation has some limitations. These limitations can be listed as the radiolucent area on the x-ray being related to the amount of bone loss caused by the lesion, the extent of the bone loss to the cortical bone, the variability of the bone structure in maxilla and mandibula, and the operator experience. The main goal in root canal treatment is to eliminate microorganisms and products in the root canal system with the irrigation agents which we use. NaOCl, which is frequently used for this purpose, is used alone or activated by Er,Cr YSSG laser. It has been reported that NaOCl, which is activated by laser, increases the elimination of microorganism in the root. The gingival crevicular fluid is an inflammatory exudate collected from the gingival sulcus. Peripheral body fluids, such as gingival crevicular fluid, can often be used as descriptors in acute and chronic inflammation. The collection of gingival crevicular fluid is a very simple and risk-free method for the patient. Biomarkers such as inflammatory mediators and neuropeptides can be detected in the gingival crevicular fluid of teeth with periodontal disease. At the molecular level, osteoclast activation is regulated by the triple molecule interaction of RANK, RANKL, and OPG. RANK (Receptor Activator of Nuclear Factor Kappa B) binds to its ligand, RANKL, while synthesizing both mature osteoclasts and its progenitor cells. RANKL provides osteoclast differentiation and activation. OPG (Osteoprotegerin) ligand is a decoy receptor for RANKL, thus inhibiting osteoclast differentiation.When the investigators look at the studies in the literature, there are many studies showing that the level of RANKL/OPG in the gingival crevicular fluid decreases with periodontal treatment. Also, when the investigators look at the studies on endodontic treatment, many mediators such as MMP-8, IL-8, Substance P, Neurokinin A and their changes after root canal treatment were examined. However, no study was found examining RANKL/OPG levels in gingival crevicular fluid after root canal treatment. At the same time, it is known that gingival crevicular fluid is used as a descriptive method in the determination of bone healing after periodontal treatment. However, in the literature, conventional radiological methods and tomography are seen as the most frequently used examination methods in the determination of bone healing after root canal treatment of lesioned teeth. The number of studies in which the gingival groove fluid collection method, which is much less invasive than these methods, is used as a descriptive method is quite limited. In line with this information, it is planned to conduct the research described below by examining the effect of activation with Er,Cr YSSG laser on the RANKL/OPG levels in the gingival crevicular fluid in the 1-3 month bone healing period after root canal treatment in lesioned teeth.

NCT ID: NCT02196740 Active, not recruiting - Periapical Diseases Clinical Trials

Research of the Application of Triple Antibiotic Paste in Primary Teeth With Pericpical Periodontitis

Start date: June 2013
Phase: N/A
Study type: Interventional

The triple antibiotic paste is widely used in young permanent teeth and permanent teeth root canal therapy with excellent antiantimicrobial effect.We hypothesize that its application in the treatment of periapical periodontitis of deciduous teeth is superior to other drugs currently in use as creosote.

NCT ID: NCT00228280 Active, not recruiting - Alveolar Bone Loss Clinical Trials

Periapical Bone Healing After Apicectomy With and Without Retrograde Root Filling

Start date: January 2005
Phase: Phase 1/Phase 2
Study type: Interventional

Ph.D project: Periapical bone healing after apicectomy with and without retrograde root filling. The aim of this study is to assess periapical bone healing after apicectomy without a filling and apicectomy combined with a retrograde filling material, MTA. Further, we will estimate risk factors in non-healing cases. Study hypothesis: There is no difference in treatment outcome between: Periapical bone healing after apicectomy with retrograde root filling and Periapical bone healing after apicectomy without retrograde root filling
