Guidelines for non-surgical root canal treatment.

Guidelines were developed by the Australian Society of Endodontology Inc. with the intent to describe relevant aspects of contemporary evidence-based root canal treatment. The document aims to support clinicians by describing a Standard of Practice in the Australian context. The presented guidelines refer to Competence criteria and Quality standards for the main steps in root canal treatment. While the intent is not to replace individual clinical decision-making, it is envisaged that these periodically reviewable guidelines may help to improve clinical outcomes.

Management of dental pain in primary care.

Patients sometimes present to a medical practitioner with dental pain if they cannot see a dentist Doctors need to be aware of the common dental diseases that result in pain so they can help to manage the patient's symptoms until they are able to see a dentist Appropriate advice regarding analgesics for dental pain is important. Paracetamol and ibuprofen are more effective in combination than either of them alone, with or without opioids Antibiotics are only indicated as an adjunct to dental treatment when there are signs of systemic involvement, progressive and rapid spread of infection, or when the patient is immunocompromised

Bleaching of a Discolored Tooth with Retrieval of Remnants after Successful Regenerative Endodontics.

INTRODUCTION: This report presents the retrieval of remnants from a discolored mandibular right second premolar (tooth #29) of a 17-year-old female after a successful regenerative endodontic procedure (REP). METHODS: The REP was performed in October 2011. Coronal discoloration became of great concern to the patient at a review visit in 2016. A cone-beam computed tomographic scan was taken to investigate the formation of hard tissues within the root canal as well as a region of no calcified tissue formation. During internal bleaching of tooth #29, a black material with particulate inclusions was retrieved and examined histopathologically. RESULTS: Five years after the REP, there was complete periapical healing, hard tissue formation within the root canal, and complete maturation of the root apex. A hard tissue bridge was noted at the cementoenamel junction when the pulp chamber of #29 was reaccessed. The remnants retrieved from the pulp chamber were confirmed to be partly mineral trioxide aggregate (MTA). A normal tooth color was achieved after 3 weeks of internal bleaching. CONCLUSIONS: MTA remnants within the pulp chamber contributed to the tooth discoloration and appear to have obstructed hard tissue formation. A matrix of oxidized regenerated cellulose seems not to hinder tissue regeneration and is resorbed by these tissues. Other materials with color stability should be selected as coronal barriers for REPs to avoid a potential adverse effect of the MTA on the REP outcome and discoloration.

Delayed Root Development by Displaced Mineral Trioxide Aggregate after Regenerative Endodontics: A Case Report.

INTRODUCTION: This case report presents the treatment of a 16-year-old boy with a maxillary lateral incisor (tooth #10) presenting with Oehlers type II dens invaginatus and diagnosed with previously initiated therapy and asymptomatic apical periodontitis. METHODS: A regenerative endodontic procedure (REP) was performed for the tooth but complicated by apically displaced mineral trioxide aggregate (MTA). Clinical and radiographic examination was undertaken yearly, and a cone-beam computed tomography scan was taken to investigate further the formation of hard tissues within the root canal. Subsequently, tooth #10 was re-accessed and then root-filled with MTA. RESULTS: There was complete periapical healing, thickening of the dentinal root walls, and completed apex formation 3 years after REP. Hard tissue formation was noted within the root canal, on the root canal wall, and the root apex through clinical and radiographic examination. Less hard tissue formation was noted on the labial root canal wall where the displaced MTA was located, which was identified on the cone-beam computed tomography scan. CONCLUSIONS: This report demonstrates that REP can potentially provide excellent treatment outcomes for structurally compromised teeth. REP should be considered as a first-line treatment before proceeding with a root filling when root development is incomplete, but attention to technical detail is essential.
