speckle images (LSI) it is possible to acquire information on the microstructure of the enamel and detect minimal changes, such as early non-carious lesions. No clinical data has been published to demonstrate the effectiveness of this technique in vivo. Prevention and management The causes of dental erosion are classified into two main categories – intrinsic and extrinsic. The former is due to regurgitated gastric acid from the stomach while the latter is from dietary, medicinal, occupational & recreational origins. It is important to recognise it early, detect its cause and provide relevant advice or treatment to stop its progression. Strategies for prevention and management consist of the following: Where intrinsic sources of acid have been identified: A: Individuals Consult a medical doctor immediately if you notice or are aware of any signs and symptoms of gastroesophageal reflux disease (GERD), such as acid reflux and heartburn, or if you suffer from an eating disorder or chronic alcoholism. They can confirm the diagnosis and develop a treatment plan accordingly. Be cautious when purchasing the following items: vitamin C, iron-tonic and amino-acid tablets, aspirin, hydrogen chloride-based preparations, asthma medications, mouthrinses with low pH, paediatric syrup medication, acidic salivary substitutes and bleaching agents. They can potentially lead to erosion. B: Dental professionals Prescribe or administer a neutralising agent, such as antacid tablets in suspension. Antacids helps neutralise stomach acidity and inhibit proteolytic activity of pepsin, both of which provide relief to symptoms of GERD such as heartburn. Note that antacids may interfere with other medications and are not suitable for women who are pregnant or breastfeeding, those that suffer from liver disease, kidney disease or heart failure and an illness associated with sodium control, such as high blood pressure or cirrhosis. Encourage patients to maintain their body mass index (BMI) within normal range or by making healthy lifestyle changes in relation to diet and exercise. Obesity is said to be an important risk factor in the development and deterioration of GERD. Find out if the patient has any underlying medical conditions or did consider a change of medications that induce hyposalivation and vomiting. If the patient displays severe signs or symptoms, referral to a medical doctor is necessary. Refer patients to a dietician for them to receive personalised dietary counselling if signs and symptoms still persist. Request that patients complete the SCOFF questionnaire, a valid and reliable screening tool for early detection and treatment
