![]() Pulp necrosis, symptomatic and asymptomatic AP, acute and chronic apical abscess with one or more teeth with post-treatment AP, radiographically determined and further validated by CBCT imaging, is diagnosed in all patients. A patient data sheet has been given and consent has been obtained.Ī total of 20 patients (12 female and 8 male, within an age range of 21–57 years) with 20 teeth (9 M, 6 premolars, 1 canine and 4 incisors) were recruited to the study based on their referral for NSRCT or NSReTx between October 2018 and March 2020 in B&R private Dental Center in Sulaimani City Kurdistan region/Iraq. The Ethics Committee of the University of Sulaimani College of Dentistry has accepted the current observational report (No. This study has been reported in line with PROCESS criteria. ![]() Thus, the goal of this case series reports was to assess the usefulness of reciprocating WaveOne Gold files and single cone endodontic treatment approach in healing of AP. There are scant reports to determine the healing of AP using conventional radiography. Therefore, the treatment outcomes of NSRCT and NSReTX have been evaluated based on the clinical and radiographic signs and symptoms such as the absence of swelling, sinus tracts, evaluation of the size of AP lesions post-operatively, and full restitution of the space of the lamina dura and periodontal ligament (PDL). įollowing the completion of non-surgical root canal treatment (NSRCT) or non-surgical retreatment (NSReTx), due to technical and ethical concerns it is not possible to obtain histological data to assess the healing of AP. Thanks to its biocompatibility with apical and periapical tissues, greater bond strength with dentin, and stronger protection of the chemistry of epoxy amines, the resin-based epoxy sealer AH Plus (Dentsply/DeTrey, Konstanz, Germany) has recently been commonly used, so that the material no longer releases toxins. Over time, root canal sealers of different formulations have been created. On the other hand, shorter procedure length with WOG reciprocating files (primarily during instrumentation) allows more time for the irrigation solution to disinfect the root canal efficiently, leading to a reduction in the microbial content of the root canal system and hence better healing for AP. One of the recent major advances in endodontic therapy is root canal preparation with a WaveOne Gold (WOG) reciprocating single-file system, mainly because of its flexibility that extends the life span of the M-Wire alloys, and reduces preparation time moreover, it allows a matching-taper single cone to fill the canal, which is simpler than other strategies for filling the root canal and has become a common endodontic therapy procedure. However, cone-beam computed tomography (CBCT) is a non-invasive process useful in the detection of additional roots and root canals in a three-dimensional view and more accurate in detection of AP. ![]() Ĭonventional and digital two dimensional periapical radiographs are still considered as the gold standard tools to assess root canal anatomy, treatment outcome and diagnosis of AP. Post-treatment AP is associated with clinical procedures that may not follow appropriate requirements and thus do not adequately regulate the infection of the root canal due to anatomical variations such as isthmuses, lateral canals, recesses and dentinal tubules these anatomical variations are typically inaccessible to the instrumentation of the root canal and antimicrobial agents used during root canal treatment. Consequently, the host's immune response activation results in local acute and/or chronic inflammation, bone resorption and periapical tissue degradation, and periapical lesion development. Microorganism colonization contributes to dental pulp necrosis and infection growth in the periapical area of the infected tooth. Apical periodontitis is an inflammatory disorder mainly caused by dental caries, accidental trauma or iatrogenic causes of exposure of essential pulp to various oral microbiota. Endodontic treatment is directed at preventing or curing apical periodontitis (AP).
