PROCEDURE

Photobiomodulation + Restoration with Self-cure Composite Resin

"1. Initial periapical radiograph;~2. Hypersensitivity reading (visual analogue scale for subjective pain of volunteer and SCASS for examiner's assessment);~3. Application of photobiomodulation;~4. Relative isolation (lip bumper, cotton roll and aspirator);~5. Selective removal of carious tissue with curette (only Code 6 of MIH-SSS criteria);~6. Cleaning with cotton and water;~7. Application of primer (Stela; SDI, Melbourne, Vic, Australia) on dentin and/or enamel, wait 5 seconds;~8. Application of mild compressed air on adhesive for 3 seconds;~9. Restoration with self-cure composite resin (Stela; SDI, Melbourne, Vic, Australia) extending to adjacent demarcated opacities;~10. Clinical follow up after 48 hours and at four-month intervals for a period of 12 months;~11. Hypersensitivity reading after 48 hours and at four-month intervals for a period of 12 months."

PROCEDURE

Photobiomodulation + Restoration with Photopolymerizable Bulk-fill Composite Resin

"1. Initial periapical radiograph;~2. Hypersensitivity reading (visual analogue scale for subjective pain of volunteer and SCASS for examiner's assessment;~3. Relative isolation;~4. Application of photobiomodulation;~5. Selective removal of carious tissue with curette (only Code 6 of MIH-SSS criteria);~6. Selective etching of enamel adjacent to demarcated opacities with 35% phosphoric acid for 20s;~7. Active application of universal adhesive (Ambar) on dentin and enamel for 20 seconds (repeat procedure);~8. Application of mild compressed air on adhesive for 5 seconds;~9. Photoactivation for 10s;~10. Restoration with Tetric N Ceram bulk-fill composite resin; with increments up to 4 mm, extending to demarcated opacities;~11. Photoactivation for 10 seconds;~12. Clinical follow up after 48 hours and at four-month intervals for a period of 12 months;~13. Hypersensitivity reading after 48 hours and at four-month intervals for a period of 12 months."
