Root dentine translucency is, in humans, an age related physiological feature. In the dentine of teeth in adult humans the tubecular microstructures fill with a highly crystalline substance making them become nearly invisible when looked at in normal light. This process starts from the apical foramen in early adulthood, and progresses up the tooth into advanced old age. Solheim (Lucy et al., 1996) collected data on age, root dentine translucency for 71 maxillary second incisors from a Norweigian population. The sex of each individual was also noted.
