Light has variable properties that influence our perception. Daylight regarded standard source Conversely, lack optimal circumstances during different times day necessitates using artificial illuminants select This study was carried out compare accuracy shade-matching (SMILE LINE) daylight. Methods: This followed STROBE (Strengthening Reporting Observational Studies in Epidemiology) guidelines cross-sectional studies. comprised 125 participants ages ranging from 20 30 years. Five observers Department Prosthodontics, Sharad Pawar Dental College (SPDC), Wardha selected maxillary central incisor subjects under sunlight, dental operatory statistical analysis performed SPSS software, Kappa statistics were used shades with sunlight. Results: A strong correlation discovered between matching sunlight four five observers. Conclusions: correcting device gives comparable those ideal conditions making useful alternative selection.
