A depth-resolved quantitative evaluation method for non-carious cervical lesions treatment with optical coherence...

Area of Science:

• Dental materials science
• Biomedical imaging
• Restorative dentistry

Background:

• Non-cancerous cervical lesions (NCCLs) require effective treatment and prognostic assessment.
• Current methods may have limitations in evaluating treatment outcomes non-invasively.

Purpose of the Study:

• To evaluate the prognostic assessment of surface smoothness and internal bubble presence after NCCLs treatment.
• To determine the utility of optical coherence tomography (OCT) in analyzing NCCLs treatment outcomes.

Main Methods:

• Non-cancerous cervical lesions (NCCLs) were treated, and samples were analyzed using optical coherence tomography (OCT).
• OCT cross-sectional images were used to assess surface smoothness and detect internal bubbles within the resin.
• An algorithm was employed to quantitatively analyze resin volume and generate 3D images.

Main Results:

• OCT successfully confirmed surface smoothness and the presence of internal bubbles in treated NCCLs.
• Quantitative analysis revealed resin volumes ranging from 3.7216 to 14.889 mm³.
• 3D visualization of resin sections was achieved through OCT imaging.

Conclusions:

• Optical coherence tomography (OCT) offers a distinctive advantage in measuring surface abrasion and internal bubble characteristics.
• OCT serves as a significant tool for both qualitative and quantitative analysis of dental NCCLs treatment.
• OCT findings may establish a gold standard for determining the prognosis of NCCLs treatment.
