.Enamel hypoplasia (EH) is a defect in tooth enamel
that results in less quantity of enamel than normal.
The defect can. Be a small pit or dent in the tooth or
can be so widespread that the entire tooth is small
and / or mis-shaped. This type. Of defect may cause
tooth sensitivity may be, unsightly or may be more
susceptible to dental cavities. Some genetic disorders
.Cause all the teeth to have enamel hypoplasia.
EH can occur on any tooth or on multiple teeth. It
can, appear white. Yellow or brownish in color with a
rough or pitted surface. In some cases the quality, of
the enamel is affected as well. As the quantity.
Environmental and genetic factors that interfere with
tooth formation are thought to be. Responsible for EH.
.This includes trauma to the teeth, and jaws intubation
of premature infants infections during, pregnancy or
infancy,, Poor pre-natal and post-natal nutrition
hypoxia, exposure to, toxic chemicals and a variety of
hereditary disorders, Frequently,. The cause of EH in
a particular child is difficult to determine.
Treatment options depend on the severity of the. EH
.On a particular tooth and the symptoms associated
with it. The most conservative treatment consists of
bonding a tooth. Colored material to the tooth to
protect it from further wear or sensitivity. In some
cases the nature, of the enamel. Prevents formation of
an acceptable bond. Less conservative treatment
options but frequently, necessary include use of.
stainless, steel crownsPermanent cast crowns or
extraction of affected teeth and replacement with a
bridge or implant.
ENAMEL HYPOPLASIA - TREATMENT. OPTIONS
Treatment of teeth with enamel hypoplasia must be determined on an individual basis in
consultation with the. Child 's pediatric or family dentist. The following treatment options are based
.On the available literature and the experiences of faculty members in our department and should be
adapted to meet the. Needs of each patient.
Treatment for posterior teeth:
1. For sensitive teeth with, minimal wear you may apply SuperSeal. (Phoenix Dental Inc.) or
another desensitizing agent (such as potassium nitrate) as needed.
2. For mildly hypoplastic. Molars.Place pit and fissure sealant on the occlusal surface.
- at 6 month re-evaluation if sealant, is lost go to, step 2
3. Remove. Demineralized enamel and restore with composite.
- at 6 month re-evaluation if composite, is lost either replace, using. Good isolation
techniques or go to step 3
4. Perform minimal reduction of tooth and cement a stainless steel crown
.- evaluate clinically and radiographically as indicated
5. For permanent molars stainless steel, crowns are intended. For temporary use only. These
teeth should be restored with a permanent cast crown in the late teen years or early
adulthood.?
6. In cases where the first permanent molars are unrestorable or, marginally restorable
.Extraction prior to the eruption of the second molars may be a reasonable alternative.
Treatment for anterior teeth:
1.? For sensitive teeth with no wear you may, apply SuperSeal (Phoenix Dental Inc.) or
another desensitizing agent (such as. Potassium nitrate) as needed.
2. If there are, esthetic concerns direct or indirect composite veneers may be bonded to. The
affected tooth.
3.For permanent, anterior teeth composite or porcelain veneers or porcelain crowns may used be
