Global DMFT for 12-year-olds: 2015

The estimated global caries burden of disease in 2015, for the indicator age of 12-year-olds expressed using the DMFT index:

  • Global weighted mean DMFT value for 12 year olds in 2015: 1.86 (209 countries).
  • Percentage of countries having DMFT 3 or less (WHO goal): 73% (153 out of 209 countries) (96,816,837 children out of a total of 131,490,154 in 209 countries have DMFT 3 or less).
  • Globally, 244,571,686 teeth of 12-year-olds are affected by caries, out of a total of 3,681,724,312 teeth.

Data sources:

Population estimates are based on CIA- The World Fact Book, accessed in June 2015. Caries data for 12-year-olds are DMFT values presented in the CAPP database, June 2015 updates.

World population:

World population: 7,174,611,584 (at the time of estimation, July 2014).

Number of countries included in the estimation: 209; Total population in these 209 countries: 7,134,377,780; and 12-year-old population: 131,490,154.

Method used for calculation is based on that used in Bratthall's 2004 estimate (2).

Global weighted DMFT= ({DMFTi x Populationi}) / Total

Populationi : 12-year-old population in every country. This data was not specifically available in the World Fact Book, hence was calculated using the percentage of 0-14 year old of the total population and 1/14 of which was taken to be 12 year olds. 

Three countries for which either the national population or the percentage of 0-14 year old data was missing, namely Martinique, Reunion and Niue and Tokelau assoc., were given the mean of the sample countries. 

Countries with DMFT data missing: Azerbaijan, Chad, Comoros, Equatorial Guinea, Marshall Island, Monaco, Republic of Nauru, Sao Tome, Principe, Andora, Yugoslavia, Guinea, Holy see (Vatican City), Timor-Leste (same as in 2011, except Qatar and Seychelles- DMFT data made available since the last estimation)
