Brief Summary
|
Fifty participants provided verbal and written informed consent before inclusion. Three experienced clinicians, screened for color vision deficiencies, performed tooth shade assessment under standardized conditions Participants were seated in the same dental chair with examiner positioning and viewing distance kept constant The selected tooth was polished using pumice slurry before evaluation. Shade selection was performed on the middle third of the labial surface. Visual shade matching was carried out independently by each clinician using Vita Classical and Vita 3D Master shade guides under controlled lighting conditions, with examiners blinded to each other’s findings. Instrumental shade measurement was performed using a calibrated VITA Easyshade Advance spectrophotometer ensuring measurement reliability |
