Dental calculus detection using the VistaCam.

Area of Science:

• Dentistry
• Biophotonics
• Diagnostic Imaging

Background:

• Dental calculus detection is crucial for oral health.
• Existing methods for calculus detection have limitations.
• Fluorescence technology offers a novel approach to visualize oral conditions.

Purpose of the Study:

• To evaluate the efficacy of the VistaCam® intra-oral camera system in detecting dental calculus using violet light fluorescence.
• To compare fluorescence readings of supragingival and subgingival calculus with sound root surfaces and dental caries.
• To assess the influence of saliva and blood on fluorescence readings for dental calculus.

Main Methods:

• Utilized the VistaCam® intra-oral camera system emitting 405-nm violet light.
• Analyzed fluorescence scores from 60 extracted teeth with varying degrees of supragingival and subgingival calculus.
• Compared fluorescence data between calculus, sound root surfaces, and dental caries lesions.
• Investigated the impact of saliva and blood contamination on fluorescence measurements.

Main Results:

• VistaCam® fluorescence scores were significantly higher for both supragingival (1.7-3.3) and subgingival calculus (1.3-2.4) compared to sound root surfaces (0.9-1.1) and dental caries (0.9-2.2) (p < .05).
• The presence of saliva or blood did not alter the fluorescence readings for dental calculus.
• The system demonstrated clear differentiation between calculus and other oral conditions.

Conclusions:

• Violet light fluorescence shows promise as an adjunct tool for detecting dental calculus.
• The VistaCam® system provides reliable and distinct fluorescence signals for calculus detection.
• This technology could enhance clinical examinations for improved oral hygiene management.
