title: [Periodontal treatment needs in adults from Mixteca rural area in Puebla State, Mexico].
abstract: OBJECTIVE
  This study was aimed at determining periodontal treatment needs, as determined by the Community Periodontal Index of Treatment Need (CPITN), in a sample of adults from the Mixteca region of the State of Puebla, in Mexico.
  
  
  METHODS
  This was a descriptive, cross-sectional, single-centre study. Previous informed consent was obtained; 60.0 % of the sample were women whose main activity was housework (46 %), 14.0 % were farmers. Average age was 37.6 ± 13.6. Gingival and Community Periodontal Index of Treatment Need proposed by the World Health Organisation and the International Dental Federation were used; they were implemented by the same, previously-standardised researcher. Means, standard deviations and confidence intervals were calculated for dimensional variables and percentages for categorical ones.
  
  
  RESULTS
  The gingival index gave 50.0 % light gingivitis, 32.0% moderate and 14.0 % severe gingivitis. The rear superior sextants commonly showed more 4 to 5 mm pockets, the front sextants calculus and the rear inferior sextants showed calculus and bleeding. 94.0 % of the patients required periodontal treatment (3.6 sextants per patient average).
  
  
  CONCLUSIONS
  Periodontal treatment needs were high in this study; nine out of ten patients in the Mixteca region of the State of Puebla required periodontal treatment. Efforts must thus be guided towards improving oral health in indigenous communities.
