“…Comparisons between visual and instrumental shade matching methods has been an active topic in the dental literature. Some studies reported better results for dental spectrophotometers than visual methods [33][34][35] . In another study, the agreement within the observer group was significantly better than that of each device 36) .…”

The aim of this study was to compare the agreement rate (%) and color difference (ΔE*ab) of three dental color-measuring devices, with the visual shade identification. The tooth color were determined by two operators, which were advised to select a VITA classic shade tab in each other's agreement. The Shadepilot (SP), CrystalEye (CE) and ShadeVision (SV) were used to measure tooth color. Statistically analyses include agreement rate (%), color difference (ΔE*ab), McNemar test (p=0.05), Student's t-test (p=0.05) and Bland Altman scatterplots. The SP had an agreement of 56.3% with the visual shade determination, the CE 49.0% and SV 51.3%. ΔE*ab of the visually and instrumentally selected shade tabs and natural teeth were frequently above the threshold for acceptability. Comparing both methods, for SP ΔE*ab values differ in a range of clinical acceptability.

This study emphasizes the need for attention after root canal obturation. The prevention of tooth staining post-operatively is still a clinical issue that affects patients and dentists. Clinicians must be able to recognize the etiology of local intrinsic staining and even in cases of sealer-induced discoloration must be able diagnose the type of sealer that was used. The prevention of crown discoloration in endodontically-treated teeth is currently taught in all accredited graduate and post-graduate programs. ABSTRACTDespite the improvement of endodontic materials, crown discoloration induced by root *Konstantinos Ioannidis, DDS, MSc in Endodontology, specialist in Endodontics (GDC,

“…This device has the ability to measure the whole tooth surface and is based on illumination at 45 degrees and observation at 0 degrees (45/0). 15 In principle, CMDs are designed to enhance communication between clinicians and dental laboratories, but the commercialization of the dental market results in the use of different devices among different professionals. However, besides the differences in working mechanisms, the basic signal of most CMDs is an electrical current originating from sensors that are transferred into color data by internal software.…”
