Endodontic simulation model for the management of furcal perforation repair using 3D printed teeth

Background, why is this subject area of interest? The management of perforations in Endodontics can be clinically challenging and involve difficult conversations with patients. Early career practitioners may feel overwhelmed by these challenges and unsure how to tackle repair of a perforation defect. Immediate perforation repair enhances outcomes. A postgraduate study day aimed to tackle the management of perforations from a theoretical and practical perspective, allowing trainees to gain confidence in managing such cases in a simulated environment, with guidance and support. Proposed primary research question Does the use of an endodontic simulation model for the management of furcal perforation repair using 3D printed teeth enhance trainees’ confidence in managing such a clinical situation? Methods or proposed methods. A pilot educational intervention was designed. Questionnaires on the management of furcal perforations were distributed to Dental Core Trainees (DCTs) (n=9) before and after an educational intervention on the management of perforations using tricalcium silicate cements. This intervention included a practical component during which DCTs used Biodentine to repair furcal perforations in a bespoke 3D printed simulation model. Early findings/ Results Participants’ views were sought and 9 pre and post intervention questionnaires returned. No DCTs had performed perforation repair in a simulated environment before, although 5 had encountered one clinically, and 3 repaired a furcal perforation clinically. Pre-educational intervention, participants had little confidence about managing perforations. Post-intervention, DCTs had increased confidence managing furcal perforation repair and 100% said that they found the training useful. Areas where additional support and feedback would be welcome. This pilot educational intervention generated encouraging results. Further data is needed to elucidate if the training resulted in a change in clinical practice, enhancing patient outcomes.
