Endodontic emergency patients' profile and treatment outcome - a prospective cohort study.

Abstract

Background: Toothache is a debilitating condition, often with mild to excruciating pain, swelling, eating difficulties and insomnia. This study aims to delineate the profiles of patients seeking emergency dental care, focusing on the diagnosis, treatment, and outcomes following non-surgical root canal treatment.

Methods: This prospective cohort study was conducted from 2012 to 2021 at the Section for Endodontics, Department of Clinical Dentistry, University of Bergen, Norway. A total of 281 emergency patient forms were analyzed. Data registered included patient demographics, dental history, chief complaints, medications used, diagnostic results, treatments provided and outcome.

Results: A total of 272 patients (272 teeth) were included in the study. Pain was the predominant complaint (98.5%), where only 57.4% of the patients managed to localize pain to a specific tooth. The mean age of patients was 51.2 years with no significant gender differences. The maxillary right first molar (15.4%) was the most frequent tooth needing treatment. The majority of the patients had experienced pain for three days before they attended the emergency appointment. The most frequently used drug for pain management was paracetamol which was stated to have little effect. Teeth that needed endodontic treatment often had restorations rather than caries. The most frequent diagnoses were pulpitis (26.8%) followed by necrotic pulp (25.4%) and previously root filled teeth (22.8%). Root canal treatment was performed on 60% of the teeth and a success rate of 95% was registered at one-year recall.

Conclusions: There was no singular diagnostic cause leading patients to seek an emergency appointment, highlighting the necessity of a thorough diagnostic procedure. Over the counter pain medications have little effect on alleviating dental pain, often resulting in desperate measures of self-medication. 60% of the teeth needing emergency treatment had previous coronal restorations such as fillings or crowns, indicating that conservative treatment does not appear to fully protect against future pulpal disease. The good prognosis of root canal treatment for teeth with acute symptoms supports recommending dentists to attempt root canal treatment rather than opting for tooth extraction.
