ABSTRACT

Objective: To determine urinary fluoride levels in school children in a non-fluoridated area in Trinidad and Tobago.

Method: Morning urine samples were requested from 750 children aged 5 to 14 years, attending a primary school in the area of St Joseph, north west Trinidad. Urine was collected at home and brought to school in labelled plastic bottles. Urinary fluoride concentration (ppm) was measured using an ionspecific electrode.
