简要总结

Chromogenic extrinsic stains are common in children and frequently recur following conventional prophylaxis. Antimicrobial photodynamic therapy (aPDT) using methylene blue activated by red light has demonstrated antimicrobial activity against oral biofilm and may reduce stain recurrence. This pilot controlled clinical trial aims to compare conventional prophylaxis combined with methylene blue-mediated antimicrobial photodynamic therapy with conventional prophylaxis alone for preventing recurrent chromogenic extrinsic stains on deciduous teeth.

结局指标

主要结局

Recurrence of Chromogenic Extrinsic Stains

时间窗: 6 months after treatment

Recurrence of chromogenic extrinsic stains assessed by standardized clinical visual examination and recorded as the presence or absence of visible chromogenic extrinsic staining at the 6-month follow-up visit.

次要结局

  • Complete Stain Removal Assessed by Standardized Clinical Examination(Immediately after treatment)
  • Parent/Guardian Satisfaction Assessed Using a Study-Specific 5-Point Likert Satisfaction Questionnaire(Immediately after treatment and at 6 months)
