title: Bolus size for the evaluation of masticatory performance in 8-10-year-old children: a pilot study.
abstract: OBJECTIVE
  To study bolus-size of different foods in 8- to 10-year-olds and appraise if 1.7-2 g of condensation silicone (Optosil®) is an adequate size to study masticatory performance in children.
  
  
  METHODS
  Bolus-size of seven foods (carrot, almonds, sausage, banana, cookie, gummy bears, raisins) (placed in random order on a scale) was studied in 20 children, aged 8-10 years. Children picked up the amount they would normally take of each, and chewed and swallowed it (three repetitions/each).
  
  
  METHODS
  Descriptive; comparisons with ad hoc tests.
  
  
  RESULTS
  There are no gender differences in bolus-size. Bolus-size was constant but different for each food.There is no pattern of bolus-size depending on hardness. Bolus-size was largest for banana; smallest foralmonds. Bite-size for carrot (food most similar to Optosil®) is 2.6 times larger than the size used for Optosil®.
  
  
  CONCLUSIONS
  The results support using this bolus-size of the artificial-test-food to further study masticatory function in children.
