A histological procedure to determine dental age

Abstract

Sclerosis of dentine has become one of the well established indicators of ageing and age determination. In this study a new technique was reported where a photomicrographic image of a cross section of sclerotic dentine was converted to a grey scale of 256 tones and then reduced to black and white and read by computer using specially developed software. A regression analysis was applied to a sample of 62 teeth (age range 17-84 years) and an age determination within an error limit of 11 years was obtained. Using a Neural Network software however the error was reduced to 8 years.
