A survey of toothbrushes in Thailand 2004.

Abstract

This study aims to explore characteristics of toothbrushes in Thailand in 2004. Toothbrushes were randomly sampled from supermarkets and stores in Bangkok and other provinces. 61 brands and 237 models of toothbrush were sampled for examination in laboratory. There were 188 models for adults and 49 models for children. The width, length and thickness of handle, head and bristle of toothbrushes were measured by vernia caliper and digital micrometer. The digital force gauge was used to measure bristle retention. The end of bristles were examined by microscope at 60 X. The study showed that 71.3 % or 169 models had met the DOH standard of toothbrush. They were 127 models for adults and 42 models for children. 33.3 % of toothbrushes were illegal by the Consumer Protection Act because of incomplete labels. The toothbrushes which met the standard were priced between 10.00 - 83.00 bahts. The percentage of qualified toothbrushes was higher than it used to be in 2000.
