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.
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]
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.
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 ]
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]
Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
The pulp contains the blood vessels, the nerves, and connective tissue inside a tooth and provides the tooth's blood and nutrients. Pulpitis is mainly caused by bacterial infection which itself is a secondary development of caries (tooth decay). It manifests itself in the form of a toothache. [1]
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]
