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.

- 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

• 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:

• Patient complaint's:- Hypersensitivity- Aesthetic disorders

• Anamnesis morbi/vitea- Carbonated drinks- Fruit juice and wine- Bulimia & Acid reflux- Dental solutions with high PH

• Objective intra-oral examination:- Tooth wear.- Exposed dentin

Diagnosis:

Differential Diagnosis:

• Erosion

• Wedge-shaped defect

• Caries

• Abrasion

Based on patient complaints, anamnesis morbi, anamnesis vitea andClinical examination we can differentiate acidic dental erosion with:

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.- Chew sugar-free gum to produce more saliva, as this helps your teeth remineralize.- Brush with a soft toothbrush and be sure your toothpaste contains fluoride.
