Endodontic status of mandibular
premolars and molars in an adult Swedish population. A longitudinal study
1974-1985.
Petersson K.
Department of Endodontics,
The purpose of the investigation was to study the incidence of endodontic treatment and the progression of periapical disease in an adult Swedish population. A random
sample was selected in 1974 and offered a clinical and radiographic
examination. In 1985, 345 of the original 1302 persons received a follow-up
examination. The present study was based on information obtained from
radiographs of the mandibular premolar and molar
regions at the two examinations. The highest increase in people with endodontically treated teeth from 1974 to 1985 and the
highest increase in people with periapical lesions
were found in the youngest age-group, born between 1945 and 1954. New endodontic treatment, received between 1974 and 1985, was
mostly found among those who already had endodontically
treated teeth in 1974. New periapical lesions also
appeared more often in persons with endodontic
disorders in 1974.
