Dental exostosis is a medical term that refers to a benign bone growth in the oral cavity, usually on the outer surface of the jawbone. The IPA phonetic transcription for this term is [ˈdɛntəl ˌɛksəsˈtoʊsɪs], which is pronounced as "den-tl eks-uh-stoh-sis". The spelling of this word is derived from Latin root words "dens" meaning tooth, "ex" meaning out, and "ostosis" meaning bone formation. When combined, it forms the literal meaning of "bone outgrowth in the dental area".
Dental exostosis is a term used in dentistry to describe a benign bone growth or projection that occurs on the surface of the jawbone or tooth roots. It is also referred to as torus mandibularis or torus palatinus, depending on its location.
In the case of torus mandibularis, dental exostosis occurs on the inner side of the lower jaw and usually presents as a bony lump or ridge. Torus palatinus, on the other hand, refers to the presence of similar bony growth on the roof of the mouth.
The exact cause of dental exostosis is not fully understood, but it is believed to be influenced by various factors such as genetics, environmental factors, and habitual factors like teeth grinding or clenching. It often develops symmetrically and can be seen in individuals of any age, although it is typically more prevalent in middle-aged to older adults.
Dental exostosis is generally harmless and asymptomatic, meaning it does not cause pain or functional issues. However, in some cases, it may interfere with speech or chewing, leading to discomfort. In these instances, treatment is not typically required unless the bony growth causes significant problems, in which case, it can be surgically removed.
Regular dental check-ups are recommended if dental exostosis is present to monitor its growth and ensure it does not develop any complications. Although dental exostosis may look unusual or concerning, it is important to note that it is a benign condition that does not pose any significant health risks.

The word "dental exostosis" is composed of two main parts: "dental" and "exostosis".
1. "Dental" refers to anything related to the teeth or dentistry. It originates from the Latin word "dens", meaning "tooth" or "teeth". The term "dental" is used to describe various dental conditions or structures.
2. "Exostosis" is a medical term derived from the Greek words "exo", meaning "outwards", and "osteon", meaning "bone". Therefore, "exostosis" refers to the abnormal growth or formation of bone on the outer surface (usually the surface facing outward) of a bone. In the case of "dental exostosis", it specifically means the abnormal growth of bone on the surface of the tooth.
