Enamel hypocalcification is a defect of tooth enamel in which normal amounts of enamel are produced but are hypomineralized. [ 1 ] [ 2 ] In this defect the enamel is softer than normal. Some areas in enamel are hypocalcified: enamel spindles, enamel tufts, and enamel lamellae.
Dental fluorosis is a common [2] disorder, characterized by hypocalcification of tooth enamel caused by ingestion of excessive fluoride during enamel formation. [3] [needs update] It appears as a range of visual changes in enamel [4] causing degrees of intrinsic tooth discoloration, and, in some cases, physical
Enamel spindles are often confused with two other entities: enamel lamellae and enamel tufts. Lamellae are linear enamel defects that extend from the surface of the enamel towards the DEJ, or vice versa. Enamel tufts are "small, branching defects that are found only at the DEJ, protruding into the enamel towards the enamel surface.
Hypomineralization or hypocalcification, as opposed to hypoplasia, refers to a decrease in the mineral content of the enamel, not the total amount present. It can vary in its presentation, and teeth may appear visually normal or highly translucent. Affected enamel is softer and more susceptible to acid, wear and decay.
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 ...
Enamel infractions are microcracks seen within the dental enamel of a tooth. [1] They are commonly the result of dental trauma to the brittle enamel, which remains adherent to the underlying dentine. They can be seen more clearly when transillumination is used. Enamel infractions are found more often in older teeth, as the accumulated trauma is
Pitting enamel hypoplasia, in an individual with amelogenesis imperfecta. It is not always clear why PEH forms instead of other hypoplasia types, particularly linear enamel hypoplasia . However, the position on the crown, the tooth type and the cause of the disruption are all likely contributing factors.
[4] [12] These lead to a concentration of stress and flexion at the area where the enamel and cementum meet (CEJ). [ 3 ] [ 5 ] This theoretical stress concentration [ 13 ] and flexion over time causes the bonds in the enamel of the tooth to break down and either fracture or be worn away from other stressors such as erosion or abrasion.
