摘要:

氟斑牙正畸托槽粘接一直是困扰临床医生的难题。目前临床上可采用延长酸蚀时间、釉质微打磨、微预备、粘接促进剂和激光酸蚀等方法促进氟斑牙粘接,延长酸蚀时间适用于轻中度氟斑牙,操作简便,但过度酸蚀会造成釉质破坏;微打磨适用于轻度氟斑牙,需橡皮障保护,促进粘接的同时可去除表面色素沉着;微预备可显著提升各类氟斑牙粘接强度,但需磨除表层釉质;粘接促进剂可能提升中重度氟斑牙粘接强度,但现有研究结果仍存争议,需后续大样本临床研究验证;最新的激光处理无明显改善粘接强度,但能有效去除色素,无牙齿损伤,还需后续进一步研究改良。

Abstract:

Bonding of brackets to dental fluorosis has always been a difficult problem for clinicians. At present, clinical research has adopted several methods to facilitate bracket bonding, including prolonging etching time, enamel microabrasion, enamel ground, using adhesion promoter and laser etching. Prolonging etching time is suitable for mild-to-moderate dental fluorosis with easy chair-side operation; however, over-etching may cause severe tooth damage. Microabrasion can be applied to mild dental fluorosis while removing pigment deposition simultaneously; however, rubber dam protection is needed. Enamel ground can improve the bond strength to all kinds of dental fluorosis at the price of removing a relatively large amount of superficial enamel. Adhesion promoters might improve the bond strength of moderate to severe dental fluorosis; however, the current results conflict with one another. This needs further verification using larger-sample clinical trials. Laser etching has no effect on improving bond strength; however, it can remove pigment without destroying tooth enamel, which is worth further modification and enhancement.
