Objectives The aim of the study is the assessment of Nadale 1, a Neandertal deciduous tooth recently discovered in Northeasthern Italy in the De Nadale cave (Middle Palaeolithic). Together with the clear archaeological context of the site, the present study brings new insight on Neandertal behaviour and dental morphological variability. Materials and Methods We used microCT data to provide a morphological description and morphometric analysis (diameter measurements and dental tissue volumes) of the Nadale 1 human tooth. Microwear analysis, taphonomical investigation and caries identification were performed using a stereomicroscope and Scanning Electron Microscope. Results In terms of morphology (i.e. incipient tuberculum molare, marked mesial marginal ridge and well-developed mid-trigonid crest connecting the protoconid and the metaconid, deep anterior fovea) and size, Nadale 1 presents features frequently observed in Neandertal lower first deciduous molars. Microscope investigations reveal the presence of a small pit which could be correlated to an incipient caries. Discussion Nadale 1 expands the Italian Middle Palaeolithic fossil record and provides further information on Neandertal dm1s in terms of dimensional and morphological variability. Furthermore, the presence of an incipient caries brings further data on Neandertal diet.
