Root caries on a Paranthropus robustus third molar from Drimolen

An antemortem lesion on the root of a Paranthropus robustus third molar from Drimolen, South Africa, is described, which likely represents another example of caries in fossil hominins.

Dental abscesses on the maxilla of a two million-year-old early Homo specimen

The earliest hominin examples of a dental abscess shows that this individual was able to cope with several concurrent abscesses, clearly surviving for an extended period, and adds additional information to the history of dental pathology in Homo genus.

Periapical lesions in hominids: Abscesses on the maxilla of a 2 million‐year‐old early Homo specimen

These lesions in an early Homo specimen highlight that this individual used their anterior dentition extensively, to the point that the pulp chambers were exposed on multiple teeth, and suggests that other hominin genera may have been less susceptible to dental abscesses, potentially relating to dietary or behavioural differences.

Dental caries in human evolution: frequency of carious lesions in South African fossil hominins

Caries frequency typically ranges between 1-5% of teeth in non-agricultural human samples, and this pattern seemingly holds true for at least the past two million years in the hominin lineage.

Tertiary Dentine Frequencies in Extant Great Apes and Fossil Hominins

Tertiary dentine forms when an odontoblast is directly affected by stimuli, commonly through occlusal wear. In this study the presence of tertiary dentine is recorded in three South African fossil



Artificial grooves on the Krapina Neanderthal teeth.

It is argued the Krapina Neanderthals were habitually probing the interproximal dental spaces with tools as well as those which have been attributed to toothpick use in other fossil and recent populations.

Interproximal Tooth Grooves in Pacific Basin, East Asian, and New World Populations

Cylindrically-shaped grooves that occur on the interproximal surface at or near the crown root (dentine-enamel) junction in human teeth are characterized by their shape, sharp margins, horizontal

Prehistoric dentistry? P4 rotation, partial M3 impaction, toothpick grooves and other signs of manipulation in Krapina Dental Person 20.

The anomalous dental eruption features of the P4 and M3 are associated with several kinds of dental manipulations, which seem to have been palliative measures to “treat” the dental problems.

Characteristics of non-carious cervical lesions--an ex vivo study using micro computed tomography.

This study did not detect clinical evidence of enamel loss above the occlusal margin of NCCLs as would have been expected according to the general abfraction mechanism.

Noncarious Cervical Lesions as Abfraction: Etiology, Diagnosis, and Treatment Modalities of Lesions: A Review Article

The present review focuses on the etiology and all available treatment plan strategies of non-carious cervical lesions and argues that tooth brushes with other artificial forces may be the causative factors.

Toothpicking and Periodontal Disease in a Neanderthal Specimen from Cova Foradà Site (Valencia, Spain)

Two interproximal grooves have been found on the distal surfaces of the upper left Pm3 and M1 of CF-1 maxilla, which indicate heavy dental wear and periodontal disease would have caused the Cova Foradà Neanderthal specimen pain and discomfort, which the individual attempted to mitigate using some kind of dental probe.

Non-carious cervical lesions in a Nigerian population: abrasion or abfraction?

About one-third of NCCL in the present study presents an abfraction component, and two-thirds abrasion, although, right-handed brushers had more severe lesions on the opposite side of the mouth, the difference was not statistically significant.

Interproximal grooving in the Atapuerca-SH hominid dentitions.

The characteristics observed in the wear grooves of the SH teeth are compatible only with the habitual probing of interdental spaces by means of hard and inflexible objects, and dietary grit may also have contributed to the abrasion of the root walls during the motion of the dental probes.
