Enamel hypoplasias reflect periods of growth stress during childhood.

Chipping and fracturing reflects eating hard foods or using teeth as tools.

Periodontal disease reflects gum health and oral hygiene practices.

The specific wear pattern documented in the Sulawesi specimens — smooth, rounded, hollowed-out grooves at the contact points between held objects and enamel — had not been formally documented in the bioarchaeological literature before this study.

As the study notes, this does not mean that the pattern has never existed in other specimens; it means it had not been recognized and described as a distinct pathology.

The formal description of this pathology in the Sulawesi study creates a new diagnostic category that can now be applied retrospectively to other collections.
