New Digital Environment Supports Endodontic Complications Reduction: Clinically Driven Ergo-Digital Study.

Abstract

Purpose.To formulate a digital environment for clinically driven ergonomic patterns assessment among endodontists and evaluate the effectiveness of its practical implementation.Methods.The study cohort was formed out of 30 clinicians, who agreed on videorecording of their clinical working patterns during endodontic treatment using a 3-orthogonally related capturing algorithm. The human simulation tool was used for CAD-modeling of clinically driven endodontic environment, within which ergonomic parameters of each doctor were registered based on RULA (Rapid Upper Limb Assessment) and REBA (Rapid Entire Body Assessment) criteria. Associations between registered non-ergonomic patterns and the prevalence of complications noticed during endodontic treatment were evaluated under regression analysis with further data cleaning and structured prediction. Optimization of working patterns included CAD-engineering of modified cinematic chain and barycenter's coordinates interactions for each endodontist recruited in the study. Results Provided regression analysis approved statistically augmented associations between trends of endodontic complications prevalence registered among upper molars and premolars with non-ergonomic working patterns of recruited clinical dentists, represented by r=0,69 (р < 0,05) та r=0,57 (р < 0,05) (under the condition of standardized leveling any other factor influence within the individually formulated digital clinically-driven environment). Optimization of ergonomic features identified within doctor-customized CAD-engineered cinematic chain supported the reduction of endodontic complications prevalence by 31.6% and 18.5% among upper molars and premolars, respectively. Conclusions.Digitalization of clinically driven working patterns registered among endodontists supports further identification of critical issues within ergonomic sequences and provides possibilities for their optimization. Such an approach could be successfully implemented in clinical practice while helping to minimize endodontic complications prevalence.
