Sažetak
Teeth, like all other organs in the human body, are sensitive to metabolic disturbances caused by inadequate nutrition and/or various diseases. These disturbances can slow or stop the formation of dental enamel during childhood and since enamel does not have the ability of remodelling this defect known as linear enamel hypoplasia (LEH) will remain recorded until the affected part of the tooth crown is destroyed by abrasion. So, in this regard, linear enamel hypoplasia is a reliable indicator of metabolic stress during childhood, i.e. during formation of dental enamel. The aim of this study was to record frequency, distribution and timing of linear enamel hipoplasia in two early medieval (7th-10th c. AD) skeletal samples from Ireland - Augherskea and Omey Island. The presence of LEH was analysed on the permanent anterior teeth - maxillary and mandibular incisors and canines. The analysis included 61 adult individuals with permanent dentition: 21 from Augherskea and 40 from Omey Island. The frequency of LEH per individual is slightly higher in the Augherskea sample compared to the Omey Island (76.2% vs. 65.0%). The frequency of LEH per individual in both samples combined is 68.8% (42/61). The hypoplastic defects are more frequent in females than in males (85.2% vs. 75.0%). The total frequency of this pathology per tooth is 43.4% (181/417) - the highest frequency was found in canines (57.2%). A slightly higher prevalence was observed in maxillary teeth compared to mandibular (44.2% vs. 42.3%). The age ranges of LEH formation vary between 2.4 and 3.0 years for the central mandibular incisors, and 4.3 and 4.9 years for the mandibular canines. At the end, the results of this study are compared with similar data from other medieval skeletal samples and possible causes for the occurrence of LEH in past populations are discussed.
