ESTIMATION OF INTRINSIC AND EXTRINSIC ENVIRONMENT FACTORS OF AGE-RELATED TOOTH COLOUR CHANGES
Original language description
Age-related colour changes of biological objects are the results of changes in structure and properties which may reflect the influence of the extrinsic and intrinsic environment. The method discriminating these two factors has not been published yet. Adevice for colour measurement of vital erupted and impacted teeth was built from commercially fiber optic spectrometer coupled with specific custom-made parts. The rate of complex discolouration caused by the total factors decreases over the life of humans. The rate of colour changes caused by intrinsic factors is nearly constant over the life-time. Age estimation of the vital erupted teeth will be only approximate (s.d. 6.2 years), more convenient are the impacted teeth immediately after extraction (s.d. 3.1 years). Correlation between the subjects age and yellowness of b* values of impacted teeth suggests a presumably similar mechanism of colour changes in bone and impacted teeth.
