Objectives: We report the discovery and description of three human teeth from the Middle Paleolithic archaeological levels of Arbreda Cave (Serinyà, Catalonia, NE Iberian Peninsula).
Materials And Methods: The teeth, two molars (one right dm and one right M) from Level N (older than 120 kyr) and one P from Level J (dated between 71 and 44 kyr), were morphologically described based on microCT images and compared with Neanderthal and Homo sapiens specimens.
Results: The teeth belong to a minimum of three individuals: one adult and one infant from Level N and one juvenile from Level J.
Objective: Molar incisor hypomineralisation (MIH) is a developmental defect of enamel affecting the first permanent molars and often the incisors and affecting approximately 13% of the current population worldwide. Here, we aim to highlight potential differential diagnoses of MIH in archaeological collections (taphonomic discoloration, amelogenesis imperfecta, fluorosis, rachitic teeth, etc.).

Nevertheless, except for a few examples and attempts to describe them, the biological impact of these interactions on the human groups' make-up is not yet understood. The present work analyzes the biological affinities of different groups from both sides of these mountains that represent the Populations of the Middle- and Late-Neolithic by means of the dental morphology.

M. de Barandiarán from 1967 to 1974: a cranial vault fragment and seven teeth, five of which likely belonged to the same individual, although two are currently lost.

According to archaeological data, there was a coexistence of sepulchral caves and megalithic monuments at the end of the Neolithic, following the dominance of open-air pit burials during the Middle Neolithic. The aim of this work is to analyze the biological relationships between individuals representing those cultures, based on their dental morphology - the first such attempt.

Only 16 cases of isolated macrodontia of mandibular second premolars have been reported to date. Although the aetiology of this phenomenon remains unknown, many authors have related it to the control of the apoptotic process, leading to the patterning and size of dental cusps.
