The spelling of the Latin term "cuticula dentis" can be explained using IPA phonetic transcription. The first word, "cuticula," is pronounced [kuːˈtɪkjʊlə], with a long "u" sound in the first syllable and a "kj" sound for the "c." The second word, "dentis," is pronounced [ˈdɛntɪs], with the stress on the first syllable and a "t" sound for the "c." Together, these words refer to the outermost layer of the tooth, commonly known as the enamel cuticle.
Cuticula dentis, also known as the dental cuticle, is a thin layer of protein or other organic material that covers the surface of the teeth. It is a natural, protective covering that can be found in both humans and animals. The term "cuticula" is derived from the Latin word "cuticula," meaning a small skin or covering. "Dentis" refers to the teeth.
The cuticula dentis is a transparent, enamel-like layer that forms on the surface of the teeth, primarily on the crown. Its function is to protect the teeth from various external factors such as physical abrasion, chemical erosion, and bacterial invasion. It acts as a barrier that shields the underlying tooth structures, including the highly sensitive dentin and pulp, from potential damage.
The dental cuticle is secreted by specialized cells known as ameloblasts during tooth development. It is composed mainly of enamel matrix proteins, such as amelogenin and enamelins, which undergo mineralization to form the translucent enamel layer. The cuticula dentis is often thickest at the tooth's cervical region, near the gumline, and gradually thins towards the occlusal surface.
While the cuticula dentis provides an extra layer of defense for the teeth, it is relatively thin and susceptible to wearing away over time. The gradual loss of the dental cuticle due to natural wear, abrasive toothbrushing, or acidic substances can expose the dentin underneath, leading to tooth sensitivity and increased vulnerability to dental diseases such as dental caries (tooth decay) and dental erosion.
Enamel cuticle, Nasmyth’s membrane, skin of the teeth; an extremely thin cuticular layer covering the enamel of recently erupted teeth.

The phrase cuticula dentis is a combination of two Latin words: cuticula and dentis. Here is the etymology of each word:
1. Cuticula: Derived from the Latin word cutis, meaning skin. Cuticula is a diminutive form of cutis, denoting a small or thin layer of skin. In the context of dentistry, cuticula refers to a thin layer of tissue covering a part of the tooth.
2. Dentis: Derived from the Latin word dens, meaning tooth. Dentis is the genitive singular form of dens, indicating possession or association with a tooth.
When combined, cuticula dentis literally means the thin layer of skin associated with a tooth.
