Metal ortodontik braketlerde üniversal adezivlerin makaslama bağlanma dayanım kuvvetlerine etkisi

Amaç: Operatif diş hekimliğindeki gelişmeler ile birlikte bazı yeni bonding sistemleri tanıtılmıştır. Bu çalışmanın amacı son jenerasyon üniversal adezivlerin makaslama kuvvetlerine etkisinin araştırılması ve kontrol grubuyla karşılaştırılmasıdır. Gereç ve Yöntem: Çalışmada 68 adet çekilmiş insan premolar dişi kullanıldı. Örnekler dört gruba ayrıldı. 1. grupta, mine yüzeyleri asitlendi ve braketler Transbond XT (3M Unitek, Monrovia, Calif) adeziv primer ile yapıştırıldı. 2. grupta, tek basamaklı self-etch primer (Transbond plus self-etching primer, 3M Unitek, Monrovia, CA, USA) kullanıldı. 3. grupta dişler %37 lik fosforik asitle 10 saniye asitlendi ve braketler üniversal adeziv ile (Clearfil Universal Bond, Kuraray, Noritake Dental Inc.) yapıştırıldı. 4. grupta, universal adeziv self-etch modunda kullanıldı. Örneklerin makaslama bağlanma dayanım kuvvetleri varyans analiziyle (ANOVA) karşılaştırıldı. Ayrıca artık adeziv indeksi (AAİ) de değerlendirildi. Bulgular: Grupların ortalama makaslama kuvveti değerleri sırasıyla, 13,42±5,09 Mpa, 11,57±3,12 Mpa, 11,15±3,08, Mpa, 11,38±3,04 Mpa’dır. Gruplar arasında makaslama kuvvetleri ve AAİ skorları açısından anlamlı farklılık yoktu. Sonuç: Üniversal adezivler ortodontik braketlerin yapıştırılma sında asitle veya self-etch moduyla güvenle kullanılabilir.

Effect of a universal adhesive on shear bond strengths of metal orthodontic brackets

Aim: Due to the development in operative dentistry, somenew bonding systems have been presented. The aim of thisstudy was to investigate the effects of the use of a last generation universal adhesive on in vitro shear bond strengths andcompare with controls.Material and methods: This study was conducted with68-extracted human premolar. The samples divided in to fourgroups. In-group 1, enamel surfaces were etched and brackets were bonded with Transbond XT adhesive primer (3MUnitek, Monrovia, Calif). In-group 2, one-step self-etching primer (Transbond plus self-etching primer, 3M Unitek, Monrovia, CA, USA) was used. In group 3 teeth were etched 37%phosphoric acid for 10 seconds and brackets were bondedwith universal adhesive (Clearfil Universal Bond, Kuraray, Noritake Dental Inc.) In-group 4, universal adhesive was used onself-etching mode. The same adhesive paste (Transbond XT,3M Unitek, Monrovia, Calif) and light-curing times were usedin all groups. Shear bond strengths of the samples were compared with analysis of variance (ANOVA). The amount of residual adhesive index (ARI) was also evaluated.Results: The mean shear bond strength values of 4 groupswere 13.42±5.09 Mpa, 11.57±3.12 Mpa, 11.15±3.08, Mpa,11,38±3.04 Mpa, respectively. There was no significant difference between the shear bond strengths of the groups. Therewas also no significant difference between the ARI scores.Conclusion: Universal adhesives can be used safely for orthodontic bracket bonding with etch or self-etching mode.
