“…Also, the results of studies by Zenthofer et al [22], who compared the effectiveness of colour measurement with the Easyshade Advance and Easyshade Compact spectrophotometers, confirm the occurrence of discrepancies between the devices, and the existence of statistically significant difference in the accuracy of both devices (p = 0.001). The above observations are not confirmed by the results obtained by the Kalantari research group [23], who compared the Easyshade with the Shadepilot spectrophotometers and did not find statistically significant differences between the results. Tsiliagkou et al [24], who compared the measurements obtained by three spectrophotometers (Easyshade, Spectroshade, and Shadevision) with regard to the Vita Classical and Vita 3D-Master shade guides (five colours from each colour palette), obtained similar results in their studies.…”

Introduction: Tooth colour selection is one of the critical elements that guarantees a patient's satisfaction of a prosthetic restoration. There are different possible methods used in dental colour selection; however, each of them has some disadvantages. Objectives: The aim of the study was to compare the results of tooth colour selection carried out by means of two independent spectrophotometers using the same 3D-Master scale. Material and methods: The material of the study included 100 prosthetic acrylic teeth by Wiedent, divided into two equal groups (50 each) of different colours. The colour of each tooth was examined by means of two spectrophotometers: Easyshade and SpectroShade. Results: The results of the study revealed no significant difference in hue selection between both instruments, but there were significant differences in brightness and colour intensity selection between spectrophotometers. Conclusions: On the basis of the study we can conclude that the instrumental method of tooth colour selection is an objective and efficient alternative to the classical visual method, but it is still not free of errors. The results of the study confirm the high utility of the spectrophotometers in tooth colour selection in dentistry, but also reveal some differences between devices from various producers. According to the results of the study, the objectivity of spectrophotometers is limited, and it is recommended that dentists use both visual and instrumental methods simultaneously..

“…According to Liberato et al 20 , the use of equipment for color measurement is a more accurate, reproducible and reliable method than human visual assessment. Furthermore, the Easy Shade® spectrophotometer has been used to improve the color reproduction of ceramic restorations in clinical practice and in the dental laboratory 21 .…”

Introduction One of the most commonly used corrective methods for staining teeth is tooth bleaching. However, subclinical alterations may occur in the micromorphology of dental tissues during the bleaching procedure, such as increases in porosity and surface roughness. Consequently, dental enamel may become more permeable and susceptible to staining. Objective To evaluate the influence of tooth polishing after in-office bleaching treatment on color stability. Material and method Thirty-three extracted human molars were used. The teeth were cut in the mesiodistal direction to obtain two samples per tooth (total of 66). The samples were randomly divided into six groups (n=11). Before and after the bleaching treatment, the lightness of the samples and change in lightness (∆L) were determined with a digital spectrophotometer (Easy Shade). The samples were bleached with 35% hydrogen peroxide (three sessions weekly). Three groups were submitted to polishing with felt discs and polishing paste after each session. To simulate the oral conditions during the consumption of colored beverages, the samples were submitted to alternating cycles of immersion in staining solutions (coffee, red wine, and Coca Cola). Result Polishing resulted in an increase of mean lightness of 4.49 in the red wine group, 2.73 in the coffee group, and 4.08 in the cola group. The difference was significant in the red wine group (p<0.022), but not in the coffee or cola group. Conclusion Polishing after in-office bleaching using felt discs and polishing paste can reduce the degree of pigment impregnation in patient with red wine rich diet.

“…29 Comparativamente ao método visual, a literatura refere uma concordância que ronda os 41% para VC e 41,5% para VM, sendo que os resultados deste estudo com métodos espectrofotométricos apresentam valores superiores. 12,18,26,34 Embora se tenha registado um maior número de falhas nas guias da VM, verificaram -se valores médios de sensibilidade e especificidade mais elevados do que na VC. Quando analisadas as falhas nas guias, verifica -se que os dois aparelhos apresentaram mais falhas nas guias de matiz C e D da escala VC e M da escala VM.…”
