Endodontisk behandling av kalsifiserte tenner

English summary Endodontic treatment of calcified teeth. Part 1: Calcifications in the root canal system Nor Tannlegeforen Tid. 2024; 134: 940-8. Pulp canal calcifications are common and will accumulate over time in the individual’s dentition. Based on 2D- or 3D-radiographs, the degree and pattern of calcification can be described as unaffected, partially calcified, or totally calcified. The etiological factors will be decisive for the degree and pattern of calcification, and whether it is possible to locate a root canal or not. The factors can be described as local or systemic. Sensibility testing of teeth with pulp canal calcifications may respond in an unreliable way. There­fore, endodontic treatment must not be performed without the presence of clinical and radiological signs of disease in the pulp and/or periapical tissues. Endodontic treatment of calcified root canal systems is time-consuming and associated with an increased risk of procedural mishaps and loss of tooth substance. During canal search in teeth with calcified root canal system, an operating micro­scope will be necessary. Comprehensive assessment of the risks and benefits should be mandatory when treating teeth with calcified root canal systems.
