Ingrown nails are scientifically referred to as onychocryptosis. This term comes from the Greek words "onycho," meaning nail, and "cryptosis," meaning hidden or buried. Onychocryptosis occurs when the edge of the nail grows into the surrounding skin, which can lead to pain, redness, and sometimes infection. This condition is commonly seen in toenails but can also affect fingernails. The other terms provided relate to different nail conditions: onychophagy refers to nail biting, onychomycosis designates a fungal infection of the nail, and paronychia describes the inflammation of the skin around the nail. Understanding these definitions helps clarify the correct association of the term with its specific condition.
