Dental Caries Detectors, Commonly Known as Cavities or Tooth Decay
Traditional Visual Examination
For many years, the traditional method of checking for dental caries has involved visual examination by the dentist using dental mirrors and probes under adequate lighting. The dentist looks for any changes in the colour, texture or structure of the tooth surface that may indicate demineralization or decay. Though effective when lesions are visible on the outer tooth surfaces, this method has its limitations as early-stage interproximal or smooth surface caries may not always be apparent visually. Moreover, visually detecting caries in children's developing dentition can be challenging.
Newer Detection Technologies
To overcome the drawbacks of visual examination alone, dentists are now making use of newer detection aids and technologies that can help identify Dental caries Detectors at their very early, non-cavitated stage before they are visible to the naked eye. Some of the commonly used advanced caries detection methods are:
Bitewing X-Rays
Dental bitewing X-rays provide a view of interdental and interproximal tooth regions that are difficult to assess visually. They allow detection of demineralization between teeth before a cavity forms. Digital radiography provides high-quality images and lower radiation dose compared to conventional films. However, X-rays expose patients to radiation and may not be suitable for frequent or routine screening.
