Filter by:Chronic inflammation plays a crucial role in the genesis of atherosclerosis and at the same time promotes acute cardiovascular events. Periodontal and pulpal inflammation are two major low grade chronic inflammatory infectious disease of oral cavity. Apical periodontitis is an inflammatory process, most often chronic in nature, of endodontic origin usually occurring at or near apex of the tooth root. The scientific literature has failed to provide the potential connection between endodontic infection and CV risk. Few studies have found the possible association, yet few studies does not suggest any link. The association between chronic inflammatory lesions and endothelial dysfunction can be detected using inflammatory, invasive and non-invasive markers. Inflammatory markers such as hs-CRP and Interleukins are not cost efficient and invasive markers- Angiography and Plethysmography are unethical to use on asymptomatic subjects. Non-invasive markers such as Flow mediated dilatation (FMD) and carotid intima media thickness (c-IMT) are inexpensive, fast and safe. The rationale of our study is to check the possible association between endodontic infection and CVD using non-invasive markers.
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).
.There is no general agreement regarding the optimal concentration of sodium hypochlorite to be used in endodontic treatment.Therefore, this study aims to evaluate the effect of sodium hypochlorite concentration on the success of primary root canal treatment. The study population comprised of patients requiring primary root canal treatment following the diagnosis of pulpal necrosis with chronic apical periodontitis in mature mandibular first and second molars.Patients were randomly allocated in either High concentration or Low concentration group.
Aim: To evaluate and compare the outcome of primary endodontic treatment following use of different instrumentation techniques. Materials and methods: Study subjects were recruited from the pool of patients referred for the non-surgical root canal treatment in the Department of Conservative Dentistry & Endodontics at PGIDS, Rohtak (Haryana). The study population comprised of patients requiring primary root canal treatment following the diagnosis of pulpal necrosis with chronic apical periodontitis in mature mandibular first and second molars. Subjects were allocated to one of the three study groups: manual instrumentation, ProTaper instrumentation and Hybrid instrumentation.
This study evaluated the effect of removal of smear layer on the success of primary root canal treatment.Patients requiring primary root canal treatment in mature mandibular first and second molars were allocated to either smear layer positive group and smear layer negative group.
In view of the wide variety of mechanized endodontic instrumentation systems, the ideal would be that the choose of this system based on the anatomical characteristics of the canal and the biological precepts. In teeth with lesions, contaminated dentin should be removed. However, in many systems, the manufacturer's approach disregards the fact that in wider root canal, instruments used in the apical third small diameter (less than 0.40 mm) may not touch the walls at the final apical. Therefore, the establishment of the initial apical file (LAI), the first instrument that measures the resistance of the walls in working length, could be a criterion in the choice of which system to use, and how many files work within the root canals after LAI determination. However, there is a lack of studies that demonstrate that LAI determination affects the degree of cleaning achieved, as well as the impact that LAI-based instrumentation may have on microcracks formation, canal transportation, postoperative pain and quality of obturation.In this way, the investigators propose a study in vivo performed, in patients from 8 to 18 years of age, therefore in large root canals. The protocol recommended by the manufacturer will be compared by means of a prospective randomized clinical trial, with the addition of the XP Endo finisher and with the protocol based on the initial apical file evaluating postoperative pain, exacerbation between the sessions, the quality of the obturation and periapical radiolucency repair. Considering that currently performing endodontic treatments using mechanized instruments is taught in undergraduate courses throughout the country, studies of this nature help the execution of a endodontics more critical and effective.
effect of occlusal reduction on post-operative pain is evaluated after single visit root canal treatment in upper and lower molar teeth in patients with sypmtomatic irreversible pulpitis and apical periondontis
Increased incidence of apical periodontitis was reported where root filling was found coronal to the marginal bone due to communication between pulp and periodontal space. It has been suggested to place intraorifice barrier in the canal to provide coronal seal. However there exists a void in literature regarding clinical validity of the termination of obturation apical to marginal bone and placement of intraorifice barrier in resolution of periapical pathology. Therefore this randomized controlled trial intends to investigate effect of coronal level of obturation on endodontic success and marginal breakdown.
