View clinical trials related to Periapical Lesion.
Filter by:Most osteotomies and apicoectomies in periapical surgeries are performed by surgical carbide or diamond burs. But greater pressure is applied during cutting which causes more thermal and mechanical damage to the bone. Also, when it comes in contact with soft tissues like nerves or vessels it results in profuse bleeding which affects vision in surgery and neurosensory disturbance at a later stage along with the deposition of metal shavings and bony particles resulting in impaired healing. The main advantages of piezoelectric surgery in various studies are highlighted as selective hard tissue cutting and sparing soft tissue, so even if it comes in contact with vessels, nerve or Schneiderian membrane it does not result in profuse bleeding, postoperative nerve damage or perforation.
The goal of this randomized clinical trial is to find the most effective Bioceramic-based apexification procedures in children with immature necrotic maxillary incisors. The main questions they aims to answer are: - What is the best Bioceramic apexification technique regarding the post-operative pain and the periapical healing ? - What is the best Bioceramic apexification technique regarding the bioceramics extrusion and the required time ? Participants will under gone Bioceramic apexification procedures which root canal preparing, disinfecting, filling, and restoring. Then, the patient will asked to come to follow-up appointments for clinical and radiological evaluations If there is a comparison group: Researchers will compare Bioceramic Putty Apical Plugs, Single Cone Gutta-percha with Bioceramic Sealer, and Combination of Bioceramic putty and sealer technique to find the best effective technique.
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.
Endodontic treatment aims to eliminate pathogenic microbes from the root canal. Hyperpure chlorine dioxide is an endodontic irrigant. Our goal is to compare the efficacy of hyperpure chlorine dioxide with the gold standard sodium hypochlorite in the non-surgical retreatment of root canal treated teeth with chronic periapical lesions in a randomized clinical trial. Forty patients having chronic apical periodontitis will randomly be chosen for the study from the patients attending our Department of Conservative Dentistry. Endodontic treatment will be done according to professional quidelines. The patients will randomly be divided into two groups. In the first (control) group sodium hypochlorite, in the second group hyperpure chlorine dioxide will be used as desinfectant. The first sample will be taken from the root canal after removing the previous root canal obturation prior to desinfection. The second sample will be taken one week after temporization. The samples will be evaluated by culturing, MALDI-ToF and PCR strip test. After root canal obturation the the periapical status will be followed by clinical evaluation and control x-rays.
Aim of this study is to evaluate the effect of i-PRF in the healing of through and through periapical lesion after periradicular surgery
The present study was conducted to test whether pulp-like tissue can be regenerated in mature teeth with closed apex? And whether the size of the apical diameter affects the success of REPs? And whether Magnetic resonance imaging (MRI) can be used to quantitatively assess the vitality of the regenerated pulp-like tissue.
This study evaluates success rate of non vital mature anterior teeth with periapical lesion treated by regenerative endodontic protocol in single visit versus two visit technique. Patients are randomized into two groups where treatment will be done either in one visit including access, disinfection, placing platelet rich plasma as scaffold and restoration or two visit protocol involving access, disinfection and placing calcium hydroxide as intracanal medicament in first visit followed by a second visit after 3 weeks involving reopening of the tooth, removing intracanal medicament and placing platelet rich plasma as scaffold then restoration. Success rate is defined as absence of subjective signs and symptoms along with healing of periapical lesion
The aim of this study is to investigate whether there was an association between obesity and periodontitis, tendency to caries and periapical lesions. People who have a higher body mass index produce cytokines (hormone-like proteins), that lead to systemic/chronic inflammation (like periodontitis and periapical lesions), and obesity related dietary habits could result in an increment of dental caries because both the amount and the frequency of sucrose ingestion are important factors associated with the aetiology of the oral disease.
