Kapiteljska njiva is a prehistoric cemetery located in the town of Novo mesto in southern Slovenia. There is a long history of archaeological research at this site, as the first investigations date back to the end of the 19th century. In 2004, an Early Iron Age barrow XVI was investigated. The oldest surviving grave in the barrow is the central grave, numbered XVI/34, which according to its position and the richness of the grave goods, belongs to a woman of higher status. Most likely, she was the first member or initiator of a family that continued to bury its dead in the barrow for the next 300 years. There were no preserved skeletal elements; however, in the head part of the grave, remains of human teeth, mostly the tooth crowns and the shells of enamel from the tooth crowns, were found among the scattered amber beads of a necklace. Moreover, these tooth remains are one of the few human biological materials (mostly fragments of skull and long limb bones) unearthed in this cemetery, reflecting the influence of acidic soil from the burial site. This study aimed to create a dental profile of the deceased in a similar way as during a forensic investigation. The remains were examined macroscopically and stereo-microscopically. The morphological traits were scored following the ASUDAS protocol. Ancestry was estimated by entering these scores into a beta version of the web-based application rASUDAS. Brothwell's system was used for age at death estimation from occlusal attrition. Identification of sex was based on the analysis of sex-specific amelogenin isoforms in dental enamel by nanoflow liquid chromatography tandem mass spectrometry (nanoLC-MS/MS). The present study reveals that the dental remains from Kapiteljska njiva belong to the permanent dentition of a single individual and that only the right upper central incisor and third molar are completely absent. The remains of teeth exhibit a simple external morphology, characterised by the absence of morphological dental traits, with a notable exception of the two-rooted left lower canine. The probability of assigning this individual to the Western Eurasian ancestry group is 98%. According to the degree of dentine exposure on the occlusal surfaces of molars, the estimated age range is 17-25 years. Another line of evidence comes from the observation that the first signs of approximal attrition are present in lower third molars but absent in the only preserved upper counterpart, indicating that the age at which the lower third molars entered into occlusion represents a proxy of the individual's age at death. Data on the chronology of the lower third molar development and eruption in present-day European populations from forensic literature (Brkić et al. 2011; Olze et al. 2008; Selmanagić et al. 2013) and The London Atlas confirm the above age-range estimate. Caution is, however, needed in the interpretation of results, because reference data are not based on the population of the individual's origin. Proteomic analysis classified the individual as a female, which is in line with the archaeological evidence. No pathological lesions or indicators of systemic stress were identified; however, the absence of approximal attrition facets in upper anterior teeth indicates interdental spacing. The results of dental profiling are discussed in the context of historical background, today's clinical knowledge, and epidemiological data.
