How does linear enamel hypoplasia form?
Enamel hypoplasia occurs when the growth of the organic matrix, which is subsequently mineralized to form enamel, is disturbed. The resulting defect may take the form of lines (Fig. 8.11. 6), furrows, pits, or large areas of missing enamel (Hillson and Bond, 1997).
Where does linear enamel hypoplasia occur?
Enamel hypoplastic defects occur on the buccal and labial surfaces of teeth and mostly commonly manifest as transverse grooves, or linear enamel hypoplasia (LEH), but also can appear as pits or grooves (Hillson & Bond, 1997).
What is linear teeth?
of tooth is involved.[3] Linear Enamel Hypoplasia is a specific type of. environmental hypoplasia characterized by multiple, symmetrical and ring like defects involving all. surfaces of teeth linking many teeth.[4] Amelogenesis.
What can enamel hypoplasia indicate on human teeth?
Depending on the location and severity of the defect, enamel hypoplasia may cause aesthetic concerns, tooth sensitivity and/or bite issues. In addition, numerous studies indicate that children with hypoplastic teeth are at increased risk for cavities.
Is enamel hypoplasia hereditary?
A wide variety of factors can potentially cause such a disturbance, including both genetic and environmental factors. The hereditary factors that lead to enamel hypoplasia in children consist primarily of relatively rare genetic disorders, such as amelogenesis imperfecta and Ellis van-Creveld syndrome.
What causes enamel Hypomineralization?
Some suspected causes include oxygen starvation, temperature (fevers), respiratory and airway issues in early life, and low birth weight. For many years antibiotic use was blamed for this condition however this is not conclusive.
How is enamel hypoplasia diagnosed?
What are the symptoms?
- pits, tiny groves, depressions, and fissures.
- white spots.
- yellowish-brown stains (where the underlying layer of dentin is exposed)
- sensitivity to heat and cold.
- lack of tooth contact, irregular wearing of teeth.
- susceptibility to acids in food and drink.
- retention of harmful bacteria.
What is the treatment for enamel hypoplasia?
Enamel Hypoplasia Treatment The most common treatment options include: Resin-bonded sealant – this treatment makes teeth less sensitive. Resin-based composite fillings – this is the best way to match the color of the sick tooth with the color of healthy teeth. Dental amalgam fillings – they are made of various metals.
What is linear enamel hypoplasia?
Linear enamel hypoplasia is a failure of the tooth enamel to develop correctly during growth, leaving bands of reduced enamel on a tooth surface. It is the most common type of enamel hypoplasia reported in clinical and archaeological samples, with other types including plane-form enamel hypoplasia and pitting enamel hypoplasia.
Is enamel hypoplasia a dental indicator of stress in Neandertals?
While previous studies generally have found high frequencies of enamel hypoplasia in Neandertals, the significance of this finding varies with frequencies of enamel hypopl … As a dental indicator of generalized physiological stress, enamel hypoplasia has been the subject of several Neandertal studies.
What is the PMID of enamel hypoplasia?
