Abstract
Objectives
White spot lesions (WSLs) are frequently observed on young permanent teeth. The aim of this clinical study was to evaluate the remineralizing effect of paste and a mouthguard containing surface pre-reacted glass-ionomer (S-PRG) filler by observing and measuring lesion area.
Materials and methods
A total of 14 children (age range, 8–16 years) with WSLs involving 74 teeth attending Asahi University Medical & Dental Center were examined. Color- and size-matching stickers (Cas Match™, Bear Medic) were photographed with involved teeth. Mouthguards made of an S-PRG filler-containing ethylene-vinyl acetate sheet (sample; SHOFU) with S-PRG filler-containing paste (PRG Pro-Care Gel®; SHOFU) (PRG MG-Paste group) or without paste (PRG MG group; control) were applied to WSLs at bedtime.
Results
No teeth required restoration due to caries progression during the experimental period. Mean reductions in lesion area at 6 months after treatment in the PRG MG-Paste group and PRG MG group were 1.66 ± 1.84 mm2 and 0.81 ± 1.27 mm2, respectively. Significant differences were observed between groups (p < 0.05). No significant difference in area reduction was seen between kinds of teeth involved, although significant differences in area reduction were observed among individual subjects.
Conclusion
These results suggest that combined use of S-PRG filler-containing paste and a mouthguard is effective for remineralization of WSLs observed on numerous teeth.
