OBJECTIVE: With respect to the unknown aetiology of molar @entity2349 (MIH), it is unclear whether this phenomenon was overlooked in the last century as a result of a high number of caries in @entity1 or if this @entity245 was not present until then. Therefore, this study determined the presence of MIH in historical dentitions and teeth. MATERIALS AND METHODS: Dental remains from late medieval (n  =  191, twelfth-sixteenth century, Regensburg, Germany), post-medieval (n  =  33, sixteenth-eighteenth century, Passau, Germany) and modern age archaeological skeletal series (n  =  99, nineteenth-twentieth century, Altdorf, Germany) were examined for MIH. In addition, @entity2193 ( @entity2193 ), diffuse @entity231 , @entity509 and Turner's teeth were documented. RESULTS: MIH-related demarcated @entity231 or enamel breakdowns were found in only 15 (0.4  %) of the 3891 examined permanent teeth. Ten cases (3.1  %) from a total of 323 dentitions were classified as having MIH. In contrast, 98 individuals (30.3  %) showed @entity2193 . Other @entity74 were recorded in 64 individuals (19.8  %). CONCLUSION: With respect to the low number of affected dentitions and teeth, MIH most likely did not exist or was at least rarely present in the investigated archaeological case series. CLINICAL RELEVANCE: This study supports the hypothesis that MIH may be linked to contemporary living conditions or other health-related factors.

Was molar XXXX (MIH) present in archaeological case series?
