Studies have shown a higher prevalence of enamel mottling in children who live in fluoridated areas than in those from low fluoride areas. It is possible that the additive effect of fluoride ingestion from water and toothpaste may be responsible since it is known that young children may swallow up to half of the toothpaste on the brush. Parents must supervise toothbrushing for young children, low fluoride paste should be used, and the brush merely smeared with paste. The commonly recommended pea-sized quantity may be too much.
研究表明，生活在氟化地区的儿童中，牙釉质斑纹的患病率高于来自低氟地区的儿童。饮用水和牙膏中摄入氟化物的叠加效应可能是原因所在，因为众所周知，幼儿刷牙时可能会咽下多达一半的牙膏。家长必须监督幼儿刷牙，应使用低氟牙膏，且只需在牙刷上涂抹少量牙膏。通常建议的豌豆大小的用量可能过多。
