Modified microabrasion protocol associated with resin infiltration. Two case reports

Area of Science:

• Dentistry
• Conservative Dentistry
• Esthetic Dentistry

Background:

• Resin infiltration effectively treats white spot lesions (WSLs).
• Incomplete resin infiltration can leave porosity in WSLs, impacting esthetics.
• Inactive WSLs present a challenge for achieving optimal esthetic outcomes.

Purpose of the Study:

• To propose and describe a modified microabrasion protocol for enamel surface treatment before resin infiltration.
• To evaluate the esthetic improvement of teeth with inactive WSLs using this modified protocol.
• To present a less invasive alternative to conventional restorative techniques for WSLs.

Main Methods:

• A step-by-step clinical protocol based on scientific literature is described.
• The protocol involves modifying the enamel surface using microabrasion prior to resin infiltration.
• Two case reports of patients with inactive WSLs are presented.

Main Results:

• The modified microabrasion protocol shows promising potential for treating deep inactive WSLs.
• Improved esthetics were achieved in patients treated with the modified protocol.
• The approach resulted in satisfactory esthetic outcomes with a less invasive method.

Conclusions:

• The modified microabrasion protocol enhances the esthetic outcome of resin infiltration for inactive WSLs.
• This technique offers a minimally invasive option for improving dental appearance.
• Further in vitro and clinical studies are required to validate effectiveness and analyze surface loss.
