Evaluation of DMFT Index in 11-16 Year- Old Children of Bavanat in 2001

DMFT is the most important index of dental caries. According to the meeting held by WHO and FDI in RiodeJenerio in 1981, the following criteria wereproposed universally: 1) 50% of children should be caries free. 2) DMFT index shouldnot be more than 3 in 12 year-old children. 3) 85% of 18 year-olds should not have anextracted tooth. The aim of this investigation was to determine the prevalence of dental caries and DMFT in 11-16 year-old school children in Bavanat. A total of 407 children (271 males and 136 females) were examined in Bavanat schools. The mean DMFT in 11-16 year-old children was 2.25%, although 95.8% of the DMFT score was related to decayed teeth (D) and only 2% of decayed teeth were filled. The means of DMFT for ages 12 + 1 and 15 + 1 were 1.9 and 2.7 respectively, which were statistically significant. The results of this study demonstrated that DMFT was 2.33 among males and 2.09 among females. The results of our investigation showed that the DMFT index in anexperimental population was relatively acceptable.
