Enamel defects in permanent maxillary incisors of Singaporean children.

Defects in development of enamel may occur as a result of a multiplicity of factors. The effect on aesthetics is of significance to the practising dental surgeon. In this connection, the prevalence and distribution of enamel defects in the permanent maxillary incisor teeth was assessed in a group of primary school children resident in Singapore from birth. The results are compared with findings from studies on communities in different countries and with varying levels of fluoride in the water supply.
