摘 要：研究處理方式和通用粘接劑光固化后唾液污染乳牙牙本質(zhì)粘接強(qiáng)度關(guān)系。選擇符合要求的80顆乳牙作為實(shí)驗(yàn)樣本，平均將其分為A、B、C、D、E組，A組為對(duì)照組，B組完全吹干的方式，C組水沖洗的方式，D組沖洗和再酸蝕15 s的方式，E組水沖洗和再酸蝕30 s的方式。對(duì)試樣進(jìn)行微拉伸強(qiáng)度測(cè)試和激光掃描共聚焦顯微鏡觀察，結(jié)果表明：微拉伸強(qiáng)度各組從大到小依次為：A、D、E、C、B組，采用完全吹干的處理方式不利于唾液污染牙本質(zhì)的粘接強(qiáng)度，B組和其他組間差異顯著（P

Treatment methods of primary teeth restoration and adhesive after light curing effect of saliva contamination on dentin bonding strength of deciduous teeth

Abstract： This paper is to study the relationship between the treatment method and the bonding strength of saliva contaminated deciduous dentin after light curing of the universal adhesive. Choose 80 deciduous teeth that meet the requirements as the experimental samples， and divide them into groups A， B， C， D， and E on average. Group A is used as the control group， and group B is completely blow-dried. Group C uses water washing， group D uses water washing and re-etching for 15 seconds， and group E uses water washing and re-etching for 30 seconds. Through the micro-tensile strength test and laser scanning confocal microscope observation of the sample， the following conclusions are obtained： the micro-tensile strength is sorted as group A>D>E> C>B， compared with the other several treatments， the completely blow-dried treatment is not conducive to the adhesive strength of saliva contaminated dentin. The difference between group B and the other four groups is statistically significant （P
