Filter by:Apical periodontitis is a dental infection which develops around the root of a tooth and affects ~4-6% of the UK population. Current treatment strategies focus solely on removing bacteria from within the root canal space during Non-Surgical Root Canal Treatment (NSRCT). Despite radical improvements in techniques available to disinfect canals, over the last 2-3 decades there has been no proportionate improvement in success rates, with ~20% of cases failing to demonstrate complete healing following NSRCT. Over time this has placed significant burden on public resources as evidenced by increased referrals to dental hospitals, extensive waiting lists and increased use of anti-microbials. It has long been known numerous bioactive molecules (dentine extracellular matrix components [dECM]) exist within the structure of the dentine. In a laboratory setting, they have demonstrated significant antibacterial properties and the ability to induce the functional processes of dental tissue repair. Through a different irrigation procedure, this research group have optimised methods for releasing dECMs during NSRCT and hypothesise this intervention could potentially promote a reduction in inflammation, improve healing and lead to more favourable outcomes for patients suffering from apical periodontitis, a concept which has not yet been investigated. It is proposed that to test this hypothesis at the Birmingham Dental Hospital by comparing clinical/radiographic signs of periradicular healing, and the molecular inflammatory response, in patients undergoing standard NSRCT (control arm) to those who having NSRCT with an irrigant regime that promotes release of dEMCs (intervention arm). Data generated from this randomised controlled pilot study will not only help to understand the process of healing following treatment of apical periodontitis at a molecular level, but also help to explore if there is therapeutic potential in enhancing dEMC release during NSRCT.
A total of 40 periapical lesions from the 33 patient undergoing apical surgery were randomly selected from December 2016-November 2017. Patients were informed about the surgical procedure and signed a consent form. Groups were divided in to 4; as control, MTA (mineral trioxide aggregate), PRF (platelet rich fibrin) and MTA+PRF groups. Apical resection was performed in all groups. No other interventions were made to the control group. Routine radiographs were taken in the 1st. 3th and 6th months. In the (approximately) 12th month of the procedures computerized tomography scans were taken. Primary healing of the periapical tissues were evaluated and the outcomes were measured. Patients have still been under control for the long term outcomes of the study.
Periodontal health may jeopardize the success of endodontic treatment.Intraorifice barrier apart from enhancing probability of success of endodontic treatment may also augment periodontal therapy as intra pulpal infection is known to contribute in worsening of periodontal health by promoting marginal bone loss and pocket formation.This study compared the apical healing in healthy and periodontally compromised teeth and evaluated the effect of intra orifice barrier and base in the healing of apical periodontitis.
Postoperative pain is a frequent complication associated with root canal treatment. The apical extrusion of irrigant and debris, including bacteria and necrotic tissue, may lead to postoperative pain, periapical inflammation, and flare-ups. The instrumentation technique and the file design may affect the amount of debris extrusion. The aim of this study was to evaluate the influence of instrumentation techniques on the incidence and intensity of postoperative pain after single-visit root canal treatment.
the aim of this study is to evaluate the effect of dental hyperalgesia and mechanical allodynia on the assessment capacity of individuals in a local Turkish population. The hypothesis of this study is that excessive amounts of pain and a major functional shift in the somatosensory system due to central sensitization might cause unwitting intent.
This study aims to evaluate an endodontic treatment protocol using adjunctive steps for disinfection of teeth with primary endodontic infections.
Maintaining Apical patency during root canal treatment is a widely followed methodology in modern endodontic treatment protocols. It involves passing of a small #08 or #10 K file through the apical foramen during root canal shaping without widening it. it is done to keep the foramen and apical thirds of root canal free of debris. proponents of the procedure claim it to improve irrigation; provide better tactile feedback; reduce the chances of procedural errors; reduce transportation and reduce pain following root canal procedures. however, there is no clinical trial which specifically evaluates the effect of apical patency on outcome of root canal procedure. hence this study was designed to evaluate the effect of apical patency on outcome of root canal treatment.
Based on various in-vitro studies intraorifice barrier has been suggested as an effective mean to provide seal against coronal microleakage. This study intends to clinically investigate efficacy of intraorifice barrier in healing of apical periodontitis.
This study will compare the effect of three different sealers on healing of teeth with apical periodontitis after primary root canal treatment.
In this clinical trial, the researchers will investigate the effect of single-file reciprocating file system (Reciproc) versus multi-file rotational file systems (ProTaper Next) on the postoperative pain in adult patients who have necrotic pulp and apical periodontitis. The participants will be assigned by chance to separate groups that compare 2 different treatments, reciprocating single-file system (Reciproc) and rotational multi-file system (ProTaper Next).
