For 6 and 12 year-old children the following is listed: • the mean CMF index: mean number (and standard deviation) of teeth present decayed teeth missing teeth and permanently filled teeth • the results on the first adult molars • the results on the other adult teeth • the proportions of children with no untreated decayed teeth (D = 0) or affected teeth (DMF = 0) as well as those without any trace of treatment (F = 0) • the treatment index calculated on children with at least one affected tooth (DF ≠ 0). It measures the proportion of teeth treated compared to all of the affected teeth - whether they are treated or not • the percentage of care needs expressed by the formula [F/DF =0] +[0< F/ DF <1] • the good dental health index • the other care needs (orthodontics hygiene gingivitis tartar) • the presence of injuries • the presence of crack and pit sealing • recourse to a dentist.
