How to Improve Your Clinical Practice by Digital Technology & Artificial Intelligence?

Abstract

In the era of digital dentistry, many labor-intensive tasks can now be assigned to, or assisted by computers, resulting in improved efficacy. Furthermore, since individual patients have unique anatomical features, risk profiles, and lifestyles, the use of digital technology is helpful in understanding individual patients and to provide personalized and precise treatment plans. This lecture will share the latest developments in digital dentistry and artificial intelligence, which can help improve the clinical workflow of your practice.

Use of Digital Diagnostic Aids for Caries Detection

Abstract

The advance in digital diagnostic techniques has significantly facilitated the detection of dental caries in recent years. Digital diagnostic aids for caries detection can be classified according to the initial source of energy. Radiography, digital transillumination imaging, light-/laser-induced fluorescence imaging, laser-induced thermal imaging, multiphoton microscopy, optical coherence tomography, ultrasonic imaging and electric-based detections are now available as digital diagnostic aids for dental caries detection to supplement the conventional visual/tactile approaches. Digital radiography uses ionizing radiation, normally X-ray to produce images of dental structures. Digital transillumination imaging shows the optical feature of the carious lesion by transmitting near-infrared light through the teeth. Light-/laser-induced fluorescence imaging detects the changes in the fluorescence induced by laser or visible lights on the carious teeth. Laser-related imaging shows the feature change of the carious lesion induced by laser. Thermal imaging shows the thermal profile of the carious teeth. Multiphoton microscopy captures the signal of laser-excited photons from carious tooth structure. Optical coherence tomography used optical coherence light to reveal the optical scattering properties of the caries lesion. Ultrasonography detects the signal of ultrasound waves to assess the acoustic impedance of the carious teeth. Electric-based detection assesses the changes in the electric current or impedance of the teeth with caries. This lecture gives an overview of the available digital diagnostic aids for caries detection.
