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.

含S-PRG填充物的护齿器和糊剂对白斑病变再矿化效果的临床评价

目的白斑病变是幼龄恒牙常见病。本临床研究的目的是通过观察和测量病变面积来评估含有表面预反应玻璃离子(S-PRG)填料的糊剂和护齿器的再矿化效果。材料与方法14例8 ~ 16岁的儿童，74颗牙齿，在旭医科大学就诊;牙科中心检查。颜色和尺寸匹配的贴纸(Cas Match™，Bear Medic)与相关牙齿一起拍照。护齿器由S-PRG填料制成，内含乙烯-醋酸乙烯片材(样品;SHOFU)含S-PRG填充膏体(PRG Pro-Care Gel®;SHOFU) (PRG MG- paste组)或不粘贴(PRG MG组);对照)在睡前应用于wsl。结果实验期间无因龋病进展而需要修复的牙齿。治疗6个月后，PRG MG- paste组和PRG MG组的平均病灶面积减少分别为1.66±1.84 mm2和0.81±1.27 mm2。组间差异有统计学意义(p <0.05)。尽管在个体受试者中观察到面积减少的显著差异，但不同类型的牙齿之间的面积减少没有显著差异。结论含S-PRG填料糊剂与护齿器联合使用可有效修复多牙釉质再矿化。
