This document defines and discusses acidic dental necrosis. It begins with a definition of dental erosion as the irreversible loss of tooth structure due to chemical dissolution by non-bacterial acids. Common causes include carbonated drinks, fruit juices, bulimia, acid reflux, and dental solutions with a low pH. Clinically, erosion presents as sensitive, discolored, rounded teeth with cracks and cups. Differential diagnosis includes erosion, wedge-shaped defects, and caries. Treatment involves applying fluoride to increase acid resistance and restorations like composites or crowns. Prevention focuses on reducing acidic drinks and foods, using straws, rinsing with water after acids, and eating acids only at mealtimes.

3. Definition:
Acid erosion, also known as dental erosion, is a type of tooth wear. It is
defined as the irreversible loss of tooth structure due to chemical
dissolution by acids not of bacterial origin. Dental erosion is the most
common chronic disease of children ages 5–17,although it is only
relatively recently that it has been recognised as a dental health
problem.

4. - chemical acidic solutions:
• Carbonated drinks
• Fruit juice and wine
• Bulimia & Acid reflux
• Dental solutions with high PH , less than 7
• Time of exposure is a big factor
- steam of mineral acids
- acid reaction of the saliva to chemical solutions
- Most of people who have necrosis work and chemical factories, and are in direct
contact with this solutions.
Etiology

5. • Sensitivity. Since protective enamel is wearing away, you may feel a twinge of pain when you
consume hot, cold or sweet food and drink. As more enamel is worn away, teeth become
increasingly sensitive.
• Discoloration. Teeth can become slightly yellow because the thinning enamel layer exposes the
underlying dentin.
• Rounded teeth. Your teeth may have a rounded or 'sand-blasted' look.
• Transparency. Your front teeth may appear slightly translucent near the biting edges.
• Advanced discoloration. Teeth may become more yellow as more dentin is exposed because of
the loss of protective tooth enamel.
• Cracks. Small cracks and roughness may appear at the edges of teeth.
• Cupping. Small dents may appear on the chewing surface of the teeth. Fillings also might
appear to be rising up out of the tooth.
Clinical Picture:

8. Differential Diagnosis:
• Erosion
• Wedge-shaped defect
• Caries
• Abrasion
Based on patient complaints, anamnesis morbi, anamnesis vitea and
Clinical examination we can differentiate acidic dental erosion with:

9. Treatment & Prophylaxis:
Formation of acid resistant structures – this mean application of the solutions with
sodium fluoride 2%, tooth paste with fluoride 75% which reduce solubility of
enamel and dentin. Restoration with composite, crowns.
- Reduce or eliminate drinking carbonated drinks. Instead, drink water, milk or tea
but skip the sugar and honey!
- If you must consume acidic drinks, drink them quickly and use a straw so that
the liquid is pushed to the back of the mouth. Don't swish them around or hold
them in your mouth for long periods.
- Don't let acidic foods linger in your mouth; swallow them as soon as you've
chewed them enough so that they are ready to digest.
- Instead of snacking on acidic foods throughout the day, eat these foods just
during meal times in order to minimize the amount of time the acid is on the
teeth.
- After consuming high-acid food or drinks, rinse with water to neutralize the
acids.
