Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Dental prophylaxis
Visit 1: tooth color assessment (by patient, dentist and spectrophotometer) and professional dental prophylaxis Visit 2: tooth color assessment (by patient, dentist and spectrophotometer)
Dental prophylaxis
Professional dental prophylaxis including dental scaling and dental polishing with prophylactic paste
Tooth color assessment by the participant
Tooth color assessment using the VITA Classical shade guide. Assessment will be done with normal light conditions and with a light correcting device
Tooth color assessment by the investigator
Tooth color assessment using the VITA Classical shade guide and the VITA Toothguide 3D Master. Assessment will be done with normal light conditions and with a light correcting device
Tooth color assessment with SpectroShade
Tooth color assessment using SpectroShade (dental spectrophotometer). Color will be registered in VITA Classical and VITA Toothguide 3D Master and CIELab parameters
