Abstract

INTRODUCTION

The bleaching of the teeth is known to reduce the bonding of the orthodontic brackets. Hence, this study was piloted to analyze if there was any variance between the teeth that were and were not bleached when the adhesive boosters were used and for its effect on the shear bond strength.

MATERIALS AND PROCEDURES

Hundred premolars (maxillary) that had been excised were randomly split into two groups: bleached teeth and unbleached teeth. The bleaching agent was gel composed of 22% carbamide peroxide. Maxillary premolar brackets were bonded, and each group was subdivided as control and adhesive booster Enhance LC groups. A universal testing device was used for debonding. The SBS thus recorded was compared for the subgroups and groups.

RESULTS

Significant variance was obtained for between the groups and between the subgroups. Higher bond strength was for the non-bleached teeth than the bleached teeth and was seen in the adhesive booster subgroup than the control group.

CONCLUSION

In summary, adhesive boosters dramatically raised the shear bond strength of teeth irrespective of the bleaching. Further studies are suggested.

摘要

引言

众所周知,牙齿漂白会降低正畸托槽的粘结力。因此,本研究旨在分析在使用粘结增强剂时,漂白牙齿和未漂白牙齿之间是否存在差异,以及其对剪切粘结强度的影响。

材料与方法

将100颗拔除的上颌前磨牙随机分为两组:漂白牙组和未漂白牙组。漂白剂为含22%过氧化脲的凝胶。粘结上颌前磨牙托槽,每组再分为对照组和粘结增强剂Enhance LC组。使用万能测试装置进行脱粘。比较各亚组和组间记录的剪切粘结强度。

结果

组间和亚组间均获得显著差异。未漂白牙齿的粘结强度高于漂白牙齿,且粘结增强剂亚组的粘结强度高于对照组。

结论

总之,无论是否漂白,粘结增强剂都能显著提高牙齿的剪切粘结强度。建议进一步研究。
