Etiology

• Faulty oral hygiene practice
  • Horizontal brushing
  • Excessive forces
• Quality of toothbrush
• pH and amount of dentifrice used
• Ill-fitting clasps of partial dentures cause localised abrasion lesions
• Fiction from toothpicks and interproximal brushes
• Tobacco Chewing

Treatment

We need to take careful consideration of aetiology and progression of the condition. That means, correct diagnosis is the prerequisite for the management of the lesion.

• If the lesion is localized and not interfering with the physiological function of the stomatognathic system = It may be restored
• If the abrasion is generalized and substantial = the habit should be discontinued and controlled
• If teeth are sensitive = use Flouride application
• If it’s class V lesion = Restoration with GIC
• If lesion involves a none conscious area in the posterior teeth = use metallic restorationon
