Douglas Bratthall and coworkers at the Dental School in Malmö have attempted to make the practical application of risk assessment more accessible by developing a computer-based caries risk assessment model called CARIOGRAM.
Cariogram - the five sectors The Cariogram, a pie circle-diagram, as seen in the screen, is divided into five sectors, (see figure below) in the following colours: green, dark blue, red, light blue and yellow indicating the different groups of factors related to dental caries. An explanation of each sector follows below.
1.The green sector shows an estimation of the ‘Actual chance to avoid new cavities’. .The green sector is ‘what is left’ when the other factors have taken their share.
2.The dark blue sector ‘Diet’ is based on a combination of diet contents and diet frequency.
3.The red sector ‘Bacteria’ is based on a combination of amount of plaque and mutans streptococci.
4.The light blue sector ‘Susceptibility’ is based on a combination of fluoride program, saliva secretion and saliva buffer capacity.
5.The yellow sector ‘Circumstances’ is based on a combination of past caries experience and related diseases.
