Localised hypoplasia of the primary canine (LHPC) is characterised by roughly circular defective areas of thinned or missing enamel on the labial surface. This defect is rarely reported in bioarchaeological research. Using samples from late prehistoric mainland Southeast Asia, this paper documents the prevalence of LHPC to produce baseline data for this defect. The samples are from seven archaeological sites in Thailand and collectively span from ca. 4000 to 1500 BP. In the combined samples, 32/79 (40.5%) of individuals and 47/199 (23.6%) of teeth had LHPC. The high occurrence of LHPC may suggest there was poor maternal and infant health. There is also a high occurrence of caries associated with LHPC, which has implications for the assessment of deciduous dental health. This paper stresses the importance of the collection of dental enamel defect data from deciduous teeth including LHPC in bioarchaeological research. (c) 2008 Elsevier Ltd. All rights reserved.
