title: A 57-year follow-up study of occlusion : part 1: oral health and attitudes to teeth among individuals with normal occlusion at the age of 8 years.
abstract: OBJECTIVE
  To analyze occlusal changes between the ages of 8 and 65 years in 18 persons with normal occlusion at the age of 8 (N-group), to describe their attitudes toward dental esthetics and their experiences regarding their dentition.
  
  
  METHODS
  The N-group is considered as the reference group in comparison with malocclusion groups that will be presented in subsequent articles. Documentation is based on intraoral photographs and personal interviews.
  
  
  RESULTS
  In general, the occlusal changes were moderate. The probands were all satisfied with their teeth and tooth position. They were all examined at regular intervals by their dentists and practiced generally good oral hygiene. The average number of missing teeth was 1.4 (0-6) and the number of prosthodontically -restored or replaced teeth was 6.4 (0-24). Fifteen persons reported well-positioned teeth to be important. However, 17 found that visibly poor oral hygiene, discolored or missing teeth or the "total impression", to be more important than malpositioned front teeth.
  
  
  CONCLUSIONS
  Generally speaking, occlusal changes were moderate and satisfaction with the dentition was good. Discolored or missing teeth and poor oral hygiene were found to be the most disturbing negative traits with respect to dental esthetics.
