The term "mastoid teeth" refers to the dental structures located in the region of the mastoid process, a part of the skull behind the ear. The word is spelled with the IPA phonetic symbols /mæstɔɪd tiθ/. The first syllable is pronounced with the short "a" sound, while the second syllable has a long "o." The "s" in "mastoid" is pronounced like a "z," and the final "d" is silent. The word "teeth" is pronounced with a short "e" sound followed by a "th" sound.
Mastoid teeth refer to a specific dental condition characterized by the presence of extra cusps or small projections on the surfaces of the molars, particularly the mandibular molars. These additional cusps are named after the mastoid process, a bony protrusion located behind the ear. The condition is sometimes also known as accessory cusps or Cusp of Carabelli.
Mastoid teeth can present in varying degrees, from minor cusps to well-developed and prominent structures. They are mainly observed on the lingual or inner side of the teeth, although they may also occur on the buccal or outer side in some cases.
This dental abnormality is considered a non-pathological trait, usually inherited and observed in about 5-10% of the population. The presence of mastoid teeth does not typically cause any detrimental effects on oral health or function. However, it can make dental procedures such as dental impressions, restorations, or root canals more challenging for dental professionals.
Identifying mastoid teeth is crucial during dental examinations and radiographic evaluations. Dentists may take note of these extra cusps while planning treatments or assessing overall dental health. The condition may also be of interest in dental anthropology and forensic odontology for studying population genetics and identifying human remains.
In summary, mastoid teeth are additional cusps found on molars, predominantly in the mandible. They are considered a benign dental variation, hereditary in nature, and generally pose no significant drawbacks to oral health.

The term "mastoid teeth" does not have a distinct etymology because it is not a recognized term in the field of dentistry or anatomy. "Mastoid" refers to a bony prominence located behind the ear, specifically the mastoid process, which is part of the temporal bone. However, there is no known dental or anatomical feature called "mastoid teeth". It is possible that the term may have been used in a localized or idiosyncratic manner, but without additional context or information, it is difficult to determine its origin or intended meaning.
