“…Although studies investigating TMJs in preindustrial populations focused mostly on Aboriginal populations (Richards, 1990;Webb, 1995), research on prehistoric hunter-gatherer populations has also been conducted (Stone et al, 2020;Suby & Giberto, 2019;Tanaka et al, 2004;Visser, 1994). Because the hardness and toughness of food can impact the development of TMJ-OA (Chen et al, 2013;Komino & Shiga, 2017;Liu et al, 2014;Peyron et al, 1997;Tran et al, 2023), it is important to identify the types of food ingested by the populations under study. In the Middle Ages, the amount of raw foods eaten was certainly lower compared with ancient hunter-gatherers, so this might not have had such a strong impact on the development of TMJ-OA as it had in earlier populations.…”

Osteoarthritis (OA) is a degenerative joint disease commonly identified in archaeological human remains. This condition primarily affects stress‐bearing joints, which include the temporomandibular joints (TMJs). Comparing dental status and degenerative alterations of the TMJs of individuals is crucial for understanding the role of the former in increasing predisposition to temporomandibular OA. The combination of visual and radiologic observations allows for a more in‐depth assessment of TMJ‐OA in archaeological specimens. A comparative study between tooth wear and the extent of degenerative signs on mandibular condylar surfaces was conducted on individuals from two medieval cemeteries in central Europe (Früebergstrasse in Baar and Dalheim). OA, tooth wear, and AMTL were evaluated in 41 individuals comprising both adult specimens as well as those of a more advanced age. Condylar OA was diagnosed in 14 individuals (Baar, n = 7; Dalheim, n = 7). No specific sex predisposition for OA in TMJs was found in the study's sample. Tooth wear was more severe in individuals with condyles affected by OA than in individuals whose condyles showed no degenerative signs. Although dental occlusion could not be evaluated, tooth wear values seem to point to diverse mastication patterns when there is unilateral or bilateral manifestation of mandibular OA in the two medieval populations under study.
