What clinical method provides the most accurate diagnosis for anterior interproximal caries?

The use of Fiber Optic Transillumination (FOTI) for diagnosing anterior interproximal caries is regarded as the most accurate method due to its ability to illuminate the tooth structure and highlight areas of demineralization or decay. FOTI works on the principle of light transmission through the tooth. Healthy enamel allows light to pass through fairly uniformly, while carious lesions will typically obstruct or scatter this light, resulting in a shadow or dark area that indicates the presence of caries.

This technique offers a non-invasive approach to caries detection, allowing for visualization of interproximal areas that may not be easily accessible through traditional examination methods, thus enhancing diagnostic precision. FOTI is particularly beneficial in anterior regions as it minimizes the risk of unnecessary tooth structure removal and preserves healthy tooth material.

While orthodontic separators are used to create space between teeth for treatment purposes, they do not provide a diagnostic method for caries. The use of caries detection solutions like methylene blue can be helpful but lacks the sensitivity and specificity of FOTI in detecting early-stage caries, particularly in the interproximal regions where light transillumination excels. Sectioning of teeth can provide definitive information about caries, but it is an invasive
