Opinions of UK General Dental Practitioners on the Restoration of Posterior Root Filled Teeth: a Vignette Survey.

OBJECTIVE: To investigate factors which influence UK general dental practitioners (GDPs) when restoring posterior root filled teeth. METHOD: An electronic survey was designed to explore current strategies of treatment of posterior root filled teeth by UK-based GDPs working in primary care. Three vignette cases included in the questionnaire explored a variety of tooth, patient, and financial factors. The survey was distributed by email and social media platforms between December 2018 and February 2019. RESULTS: A total of 528 valid responses were collected. The majority of participants (84.1%) regularly restored posterior root filled teeth with an indirect restoration. Presence of persistent symptoms post root canal treatment (RCT) completion would impact the management of 85% of the surveyed respondents. Referral to a specialist, deferral of provision of the definitive restoration, and fear of litigation were reported by the GDPs as influencing factors. CONCLUSION: This survey highlights that decision making regarding restoration of root filled teeth is a multifactorial process. Tooth, patient, and financial factors were all shown to influence the restorative management of the posterior root filled teeth.

Suspected Endodontic Failure in a Patient with Cleidocranial Dysplasia: A Case Report.

A patient's medical history and related dental manifestations can significantly contribute to confounding signs and symptoms leading to a diagnostic challenge. An 18-year-old female patient presented with persistent radiographic radiolucency associated with the apex of a previously treated tooth (tooth 9); asymptomatic apical periodontitis and endodontic failure were suspected. This report presents how a patient's condition of cleidocranial dysplasia had a profound effect on her dental history, which included the presence of multiple supernumerary teeth. Extensive surgical intervention during the patient's childhood was required to remove the supernumerary teeth, which resulted in an endodontic misdiagnosis in her adult life. After clinical and radiographic examination, the patient was diagnosed with a periapical scar. Periapical fibrous scars have a prevalence of between 2.5% and 12% and are a rare healing process with fibrous tissue after surgical and nonsurgical interventions. This report describes the diagnosis and pathophysiology of fibrous scars, including their risk factors and long-term monitoring approaches.

The epidemiology of endodontic complexity in general dental practice: a prevalence study.

Aim To determine the prevalence and the epidemiology of the factors influencing endodontic complexities in general dental practice.Method Eligible cases where endodontic treatment was indicated as a treatment option were collected by a total of 30 general dental practitioners based in the UK. Online-based Endodontic Complexity Assessment Tool (E-CAT) was used to determine the perceived complexity of each case. In total, 22 categories, including patient- and tooth-related factors, were recorded.Results Collectively, 435 non-surgical root canal treatment cases were assessed. Overall, 72% of the root canal treatments encountered in general dental practice were found to be either uncomplicated (Class I) or moderately complicated (Class II) and can be considered within the remit of general dental practitioners. Despite the relatively equal distribution of the assessed teeth, the proportion of extraction as a proposed treatment for posterior teeth was more than double that of anterior teeth.Conclusion The results obtained in this study provide a good resource and databank for researchers, educators, public health commissioners and academic institutions to access a wide range of information concerning the prevalence and distribution of endodontic complexity.
