Enamel-dentine fracture is a complete fracture of the tooth enamel and dentine without the exposure of the pulp. Pulp sensibility testing is recommended to confirm pulpal health. Treatment depends on how close the fracture is in relation to the pulp.
An enamel fracture occurs when the outer layer of the tooth, known as enamel, is fractured without directly impacting the underlying tooth tissues of the dentine or pulp. [1] This phenomenon typically arises from hard, external forces impacting the tooth to induce enamel breakage. [ 1 ]
A crack in enamel with no loss of tooth structure Tooth is not tender No abnormalities Generally no treatment needed Discolouration of prominent cracks can be prevented by etching and sealing with resin No follow-up required 2) Enamel fracture Fracture involving enamel only Tooth not tender with normal mobility and pulpal response Loss of enamel
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
Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength and function within tooth structure.
The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or through air abrasion (or in the case of atraumatic restorative treatment, hand instruments), to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are ...
Tooth wear is a very common condition that occurs in approximately 97% of the population. [2] This is a normal physiological process occurring throughout life; but with increasing lifespan of individuals and increasing retention of teeth for life, the incidence of non-carious tooth surface loss has also shown a rise. [3]
Dental restorations, such as crowns and fillings, must be designed to mimic the natural mechanical transition between enamel and dentin. Understanding the molecular architecture of the DEJ can inform the development of advanced biomaterials that better integrate with the remaining tooth structure, improving the success rate and longevity of ...
