Endodontics
Our research, both clinically and in the lab, aims to improve the quality of lives through better endodontic therapy. Endodontics is more than root canal treatment and consequently our activities include projects both related to vital pulp therapy (VPT) and to non-surgical root canal treatment (RCT).
Regarding VPT, we are exploring various aspects of diagnostic methods and the predictive value of findings at the point of service for clinical outcomes. This research is supported by in vitro studies into immunomodulatory effects of contemporary and experimental biomaterials.
For conventional RCT our work aims to improve materials and usage parameters to make modern techniques accessible to clinicians and by extension to patients. One recent study looked at the utility of finite element analysis to predict behaviour of root canal instruments in the design phase. Other experiments include the assessment of root canal filling materials.
Overarchingly, the intent and possible impact of work in our lab is shown in publications, presentations and guidelines that collectively should lead to evidence-based good clinical practice in endodontics. Therefore, we are currently looking into barriers and enables in both VTP and RCT.
