In de literatuur is de toepassing van CBCT binnen de endodontie uitgebreid beschreven. Vergeleken met de traditionele spiraal-CT resulteert CBCT met beperkt beeldveld (FOV, field of view) in een fractie van de effectief geabsorbeerde stralingsdosis. Dit artikel is bedoeld om een overzicht te geven van de toepassingen en voordelen van CBCT bij uitgebreide endodontische problemen en complicaties, terwijl de stralingsblootstelling tijdens complexe endodontische procedures wordt gereduceerd. De voordelen van de extra diagnostische informatie die intraoperatieve CBCT-beelden in geselecteerde gevallen opleveren, rechtvaardigen het risico waarmee de beperkte stralingsblootstelling gepaard gaat.

Cone beam computed tomography (CBCT) is a new technology that produces three-dimensional (3D) digital imaging at reduced cost and less radiation for the patient than traditional CT scans. It also delivers faster and easier image acquisition. By providing a 3D representation of the maxillofacial tissues in a cost- and dose-efficient manner, a better preoperative assessment can be obtained for diagnosis and treatment. This comprehensive review presents current applications of CBCT in endodontics. Specific case examples illustrate the difference in treatment planning with traditional periapical radiography versus CBCT technology.

The use of cone beam computed tomography (CBCT) in endodontics has been extensively reported in the literature. Compared with the traditional spiral computed tomography, limited field of view (FOV) CBCT results in a fraction of the effective absorbed dose of radiation. The purpose of this manuscript is to review the application and advantages associated with advanced endodontic problems and complications, while reducing radiation exposure during complex endodontic procedures. The benefits of the added diagnostic information provided by intraoperative CBCT images in select cases justify the risk associated with the limited level of radiation exposure.

Irrigants are chemically inactivated after their reaction with the biofilm and therefore need to be mixed with fresh irrigants. Insight in the flow of the irrigant during a root canal treatment is crucial to understand the importance of the disinfection of the root canal system. This chapter discusses the operational characteristics, fluid dynamics, and mechanical and chemical interactions involved with sonic activated irrigation (SAI), ultrasonic activated irrigation (UAI), and laser activated irrigation (LAI). Biofilm consists of a substantial extracellularmatrix of mainly proteins and polysaccharides (EPS, extracellular polymeric substance), which effectively protects microorganisms. Forces on the biofilm exerted by irrigant flow could disrupt the top layers of biofilm, or its EPS matrix, or could completely remove the biofilm. To obtain an optimal chemical effect of irrigants, they should be delivered throughout the root canal system and be refreshed and mixed as effectively as possible.
