Clinically, both the baby (primary) and adult (permanent) teeth often appear amber coloured and translucent, and show signs of severe attrition. Primary teeth have a more obvious appearance as they have a thinner layer of enamel overlying dentine, hence the abnormal color of dentine is more noticeable.

Desquamative gingivitis is a descriptive clinical term, not a diagnosis. [1] Dermatologic conditions cause about 75% of cases of desquamative gingivitis, and over 95% of the dermatologic cases are accounted for by either oral lichen planus or cicatricial pemphigoid. [1]
Cross-section of a tooth. B is dentin. Dentin (/ ˈ d ɛ n t ɪ n / DEN-tin) (American English) or dentine (/ ˈ d ɛ n ˌ t iː n / DEN-teen or / ˌ d ɛ n ˈ t iː n / DEN-TEEN) (British English) (Latin: substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth.
Dentin hypersensitivity is a relatively common condition. [4] [3] Due to differences in populations studied and methods of detection, the reported incidence ranges from 4-74%. [3] Dentists may under-report dentin hypersensitivity due to difficulty in diagnosing and managing the condition. [4]
Secondary dentin is darker and more opaque than primary dentin. This gives the dentin an overall darker appearance. [ 11 ] At the same time, the enamel layer is gradually thinned by tooth wear processes such as attrition and acid erosion, a degree of which is considered normal. [ 11 ]
Rather than a single disease entity, periodontal disease is a combination of multiple disease processes that share a common clinical manifestation. The cause includes both local and systemic factors. The disease consists of a chronic inflammation associated with loss of alveolar bone. Advanced disease features include pus and exudates.
Dentin dysplasia (DD) is a rare genetic developmental disorder affecting dentine production of the teeth, commonly exhibiting an autosomal dominant inheritance that causes malformation of the root. It affects both primary and permanent dentitions in approximately 1 in every 100,000 patients. [ 1 ]
