Hypomineralisation and Hypoplasia Flashcards
What is hypomineralisation
Hypomineralisation where enamel lacks minerals during the maturation and mineralisation phase.
What does hypomineralisation do
causes problems with maturation and mineralisation and results in teeth with reduced quality of enamel.
When does hypomineralisation occur
During minralisation and maturation
What are the concerns with hypomineralisation
Can result in Post eruptive breakdown of the tooth as well as cavies and eventually decay.
Hypominerlisation coloring
can result in creamy white to brown teeth. The border is either diffuse or demarcated. Can cause aesthetic problems.
Subtypes of hypomineralisation
molar incisor hypomineralisation (MIH) this affects the molars more than the incisors and can affect the first primary molars and the second primary molars.
what is PEB and what does it cause
Posteruptive breakdown is here the teeth break due to hypomineralisation it can cause sensitivity and pain.
What causes hypomineralisation
Genetic environmental and
What is hypoplasia
Hypoplasia is an oral condition that occurs during the formation of enamel that results in the quantity of enamel produced being affected.
Why does hypoplasia occur
hypoplasia occurs due to problems with the secretion of matrix proteins from ameloblasts: Amelogenin, ameloblastin, and enamelin
What does hypoplasia do to your teeth
Hypoplasia can create pits in your teeth and can create a rough border, smaller and thinner teeth.
Local hypomineralisation occurs because
Happens due to: Trauma infection Radiation Fluorosis
Generalised hypomineralisation occurs because
Happens due to:
Systemic/ environmental
Fluorosis
Only affect teeth mineralising during this period
Chronological hypomineralisation
Hypomineralisation that occurs at a specific time
Other conditions that show hypomineralisation and hypoplasia
amelogenesis imperfecta that can be localised or generalised but tends to be generalised.
