Available in PDF, EPUB and Kindle. Book excerpt: Eighty-eight (1.96%) out of 4,500 patients had teeth stained by tetracycline. The majority had yellowish-brown stains (59.1%), whilst 37.5% had greyish-brown and 3.4% had black stains. A large number of teeth (79.6%) were stained up to two-thirds of their crowns. The deciduous teeth, permanent incisors and first molars were most commonly affected (73.9%). Teeth are only stained by tetracycline if this drug is administered during their calcification periods. For aesthetic reason, the drug should not be prescribed from the fourth month of pregnancy till the seventh year of life. The social embarrasment due to such discolouration may be overcome by tooth bleaching and construction of tooth facings and crowns.
