Introducing a Specific Term to Present Caries Experience in Populations with Low Caries Prevalence: Specific Affected Caries Index (SaC)

  • Up to now, indices like the mean dmft/DMFT and the SiC (Significant Caries Index) have been used to depict caries experience in populations with high prevalence. With the caries decline, particularly for populations with low caries levels, these indices reach their statistical limits. This paper aims to introduce a specific term, the Specific affected Caries Index (SaC) for the risk groups in populations with low caries prevalence and to illustrate its use based on the consecutive German National Oral Health Survey (GNOHS) in children. In groups with a caries prevalence less than one-third of the population, many caries-free children (DMFT = 0) are included in the SiC (risk group), which calls for a new way of illustration. Mean caries experience (DMFT), caries prevalence, the SiC and SaC were portrayed for 12-year-olds in the GNOHS from 1994/95 to 2016. The SaC describes the mean caries experience (DMFT) in the group presenting caries experience (DMFT > 0). In 12-year-old 6th graders in Germany, the mean caries experience decreased from 2.4 (1994/95) to 0.4 DMFT (2016), with a recent prevalence of 21.2% (DMFT > 0, 2016). In 2016, the mean number of affected teeth in children with DMFT > 0 (SaC) was 2.1, while the SiC including 12% DMFT-free children in the risk group was 1.3. The SiC fails to reflect the caries severity in children in a population with low caries prevalence. Therefore, the newly introduced term Specific affected Caries Index (SaC) may be used to describe accurately caries experience in caries risk children in populations presenting low caries prevalence.
