title: Association between childhood obesity and oral hygiene status.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the oral hygiene status in pediatric obese patients.
  
  
  METHODS
  A cross-sectional study was conducted from 2011 to 2012, which evaluated 180 Brazilian pediatric patients, 6-14 years old, girls and boys, recruited according to two Body Mass Index (BMI) categories: obese and non-obese (healthy weight). For the evaluation the oral hygiene status, the study used Oral Hygiene Index (OHI) and Gingival Bleeding Index (GBI).
  
  
  RESULTS
  According to the total sample, 5/60 obese (8.3%) and 57/120 non-obese (47.5%) had good OHI, while 23/60 obese (38.4%) and 3/120 non-obese (2.5%) were classified in a low level of OHI, with a significance between the groups (p < 0.001), even after sorting by age. According to the classification of GBI, 60/60 obese (100.0%) and 89/120 non-obese (74.2%) had GBI 1 (bleeding gingiva), and 0/60 obese and 31/120 non-obese (25.8%) were classified as GBI 0 (healthy gingiva), with a significance between the groups (p < 0.001), even after sorting by age.
  
  
  CONCLUSIONS
  This study indicated that OHI and GBI were significantly higher in the obese children group.
