1. Clinical aspects of restorative treatment in the primary dentition
Sammanfattning : The failure rate of restorative treatment in primary teeth was studied in a cohort of children born in 1981 and related to caries diagnosis, prevalence and distribution on different tooth surfaces, and compared with a cohort of children born in 1971. Concurrently, the longevity of composite resin in modified Class 2 cavities in primary molars was followed up and the resistance of deciduous and permanent enamel to acid adjacent to composite resin and glass polyalkeonate cement (GPA) was tested in vitro.

This smear layer, which is between 1 and 10 gm thick, consists of hydroxyapatite, denatured collagen and remnants of cariogenic bacteria. If left untouched, it will weaken the bond between filling material and cavity wall. LÄS MER
