Abstract:
:The aim was to describe the prevalence and incidence of caries lesions in relation to the placement and replacement of amalgam and non-metal fillings in a randomly selected adult Danish population. In 1997 and in 2003, 470 individuals underwent a full-mouth radiographic survey. All recordings were based on radiographs. A total of 12,361 teeth were examined. Registrations were performed on surfaces: mesial, distal and occlusal or incisal. In 1997 the total number of teeth and the number of unfilled teeth per individual decreased with the age of the individual, whereas the number of caries lesions per individual did not vary systematically with age. In each age group approximately 50% of the individuals had no caries lesions. In 1997 approximately 70% of the filled surfaces were filled with amalgam and 30% with non-metal filling materials. In 2003 60% of the surfaces were amalgam-filled and 40% were non-metal-filled. Overall non-metal filling material was more frequently used than amalgam in both treatments and re-treatments. During the observation period approximately 20% of both amalgam and non-metal-filled surfaces were re-treated. For amalgam fillings this was constant across the tooth groups, but for non-metal fillings the percentage of re-treated surfaces was larger for molars. The percentage of teeth with caries increased from front teeth to posterior teeth. The lowest percentage of surfaces with caries was detected in unfilled surfaces, and the highest in non-metal-filled surfaces. The results from the present study suggest the need for reflection and diligence when using non-metal materials for dental fillings especially in relation to molars.
