Exploring The Potential Of Diagnodent In Caries Diagnosis 

Of all the oral problems, dental caries is the most prevalent one affecting millions of all age groups worldwide. Early detection is the key to a successful treatment in restoring your tooth and saving yourself from extractions. Modern dentistry has evolved over the recent years through innovative diagnostic aids like Diagnodent. This is a revolutionary invention that is much more accurate than dental X-rays. 

Diganodent is widely used by dentist in Downtown Chicago for their patients to diagnose dental caries at an early stage. 

A Comprehensive Guide to Diagnodent 

Diagnodent is an advanced and modern laser-assisted diagnostic aid that helps detect tooth cavities at an early stage. It can effectively spot even the smallest lesions at the earliest stage without having to scrape, probe, or open up the affected tooth. Over the past decades, Diagnodent has been considered to be over 90% accurate when compared to dental examinations and X-rays. 

Understanding the principle behind Diagnodent

Diagnodent is a safe, simple, and painless way of identifying caries. It consists of a hand-held, pen-like device or probe connected to a monitor or screen. This probe emits laser light into the tooth to measure the internal fluorescence. The laser operates at a specific wavelength and uses two-way optics to adjust the amount of light reflected out of the tooth. The readings are recorded on the monitor. A higher reading indicates a greater level of tooth decay.

Result Interpretation 

  • 10 to 15: No cavity detected 
  • 15 to 30: Preventive care recommended 
  • 30 and up: Extensive restorative treatment recommended 

Benefits of using Diagnodent 

Diagnodent is a revolutionary diagnostic tool for caries that is gaining popularity, due to the following benefits:

  • Exposes caries at an early stage
  • Does not involve scraping or opening the tooth
  • Safe and painless 
  • Cost-effective
  • Provides accurate results
  • No exposure to radiation involved in X-rays thus can be safely used for pregnant, and lactating women
  • Less time-consuming 

The process of using a Diagnodent  

The steps involved in using a Diagnodent are as follows:

  • Your dentist will isolate the suspected tooth with a rubber dam to control moisture, which can lead to false positive results.
  • The Diagnodent will be switched on, and the probe will be carefully held over the tooth. 
  • The device will be moved near the occlusal (chewing) surfaces, the interdental (between the teeth) areas, the buccal/labial surface, and the palatal/lingual surface. 
  • The readings will be recorded on the monitor, and the results will be interpreted by your dentist accordingly.   


Diagnodent is a laser-assisted inspection device utilized for the early detection of tooth decay, especially in areas not accessible to the naked eye. Such revolutionary diagnostic tools have been gaining popularity since they spare you from painful extensive dental procedures like extraction.
