Which term describes nails that have been bitten?

The term that describes nails that have been bitten is onychophagy. This condition is characterized by the habitual biting of the nails, which can lead to various issues, including damaged nail beds, infections, and changes in the nail's appearance. This behavior is often associated with stress or anxiety and can occur in both children and adults. Onychophagy is not simply a cosmetic issue but can also indicate underlying emotional problems and may require behavioral intervention.

In contrast, the other terms refer to different nail conditions. Onycorexis pertains to brittle nails that exhibit longitudinal ridges or splits, often related to various health issues or environmental factors. Pincer nails describe a condition where the sides of the nails curve inward, which can cause discomfort and make nails appear tapered. Plicatured nails refer to nails that have an abnormal fold or a pronounced curvature due to the deformation of the nail plate. Each of these conditions affects the nails in distinct ways, highlighting that onychophagy specifically relates to the action of biting the nails.
