Abstract:
A comparison of the results of the Adult Dental Health Surveys in England and Wales in 1968 and England, Wales and Northern Ireland in 2009 shows marked improvements in many aspects of oral health. Edentulousness in adults aged 16 years and over has reduced from 37% to 6%. Dentate adults today have 9 to 10 more sound teeth in all age groups up to 44 years, than was the case 40 years ago. The number of decayed or unsound teeth has halved in every age group between 1968 and 2009.

Tooth Anatomy
The Crown, Neck, and Root
