2. Caries Assessment Spectrum and Treatment (CAST)
Caries detection is fundamental to understanding the oral health status of a population
Different instruments are available for epidemiological surveys ⟹ CAST
CAST aims to provide relevant information by assessing a wider spectrum of the caries status than others instruments
CAST CAST CAST CAST CAST CAST CAST CAST CAST 8

3. F = 0.25*CAST3 + 1*CAST4 + 2*CAST5 + 4*CAST6 + 5*CAST7 + 6*CAST8
Reporting Results
Using CAST the caries prevalence calculation does not include restored and teeth missing due to caries
CAST records a tooth with pulpal involved (Code 6) and with an abcess (Code 7)
A population can be grouped in five stages of disease: healthy, pre- morbidity, morbidity, severe morbidity and mortality
CAST codes are hierarchically ordered
The severity level of dental caries can be calculated according to a formula which gives a progressively higher weight as the codes increase. It is called the CAST severity score
F = 0.25*CAST3 + 1*CAST4 + 2*CAST5 + 4*CAST6 + 5*CAST7 + 6*CAST8

4. e-Charting Platform
It’s a cloud-based-platform in which statistics are automatically processed
AIM: To assess oral health of a population by charting patients in the cloud, by automatically calculating their individual severity codes and by automatically generating severity statistics.

5. Methodology
Oral health data from an epidemiological surveys (680 school children) carried out in 2 schools in Brasília, Brazil were used
The original data were collected by paper and manually entered into a database. Data were handled by a biostatistician
The same oral health data were entred into na e-charting programme that is available in the cloud.

A small insignificant difference between manual and paperless (e-Charting) was present in each of the categories

7. Conclusion
DentalCharting appears to be a reliable tool which significantly speeds up data collection, data processing and data analysis in oral health surveys in the absence of paper records
