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.
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.
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 ]
Internal resorption is defined by the loss of intraradicular dentin and tubular dentin from within the middle and apical thirds of the root canal(s). It may also present as an incidental, radiographic finding. Radiographically, a radiolucent area of uniform density within the root canal may be visible with well-defined borders.
Dentin formation, known as dentinogenesis, is the first identifiable feature in the crown stage of tooth development. The formation of dentin must always occur before the formation of enamel. The different stages of dentin formation result in different types of dentin: mantle dentin, primary dentin, secondary dentin, and tertiary dentin. [31]
Secondary Caries: Exposed dentin is more prone to bacterial colonization, leading to the risk of developing caries at the fracture site, especially if oral hygiene is compromised. (Yu CY, Abbott PV, 2016) Secondary caries; Hypersensitivity: Dentin exposure can cause ongoing sensitivity to temperature changes, sweet or acidic foods, and even air ...
The disease is most common in Latin American countries, countries in the Middle East, and South Asia, and least prevalent in China. [149] In the United States, dental caries is the most common chronic childhood disease, being at least five times more common than asthma. [150] It is the primary pathological cause of tooth loss in children. [151]
There are three types of dentin, primary, secondary and tertiary. [19] Secondary dentin is a layer of dentin produced after root formation and continues to form with age. Tertiary dentin is created in response to stimulus, such as cavities and tooth wear. [20]
