The indicatorDMFT=0 (dmft=0 for infant teeth) refers to decay-free teeth.Source: Jamieson, Armfield and Roberts-Thomson (2006a); table 5A.5.1 and 5A.5.2.• The mean (average) number of infant teeth with decay was higher forIndigenous children than non-Indigenous children across all ages (from four to10 years) and for both metropolitan and rural areas (table 5.5.1).• The highest number of infant teeth with decay for Indigenous children was 2.89for children four years of age in metropolitan areas and 4.13 for five-year-oldIndigenous children living in rural areas (table 5.5.1).• The mean number of permanent (adult) teeth with decay was higher forIndigenous children than non-Indigenous children across all ages except forseven-year-olds in metropolitan areas (both had the same DMFT score of 0.22)(table 5.5.1).• The mean number of permanent teeth with decay for Indigenous children livingin metropolitan areas ranged from 0.13 for six-year-olds to 1.83 for 14-year-olds,compared with 0.08 for non-Indigenous six-year-olds and 1.18 fornon-Indigenous 14-year-olds (table 5.5.1).EARLY CHILDDEVELOPMENT ANDGROWTH5.37
