Influence of caries detection dye on bond strength of sound and carious affected dentin: An in-vitro study

Abstract

Objectives:The objective of this study was to evaluate the influence of caries detection dye on the in-vitro tensile bond strength of adhesive materials to sound and carious affected dentin.Materials and Methods:Forty healthy and carious human molars were ground to expose superficial sound dentin and carious affected dentin. Caries Detector dye was applied to sound and carious affected dentin and rinsed. Subsequently the dentin was etched with 37% phosphoric acid and rinsed leaving a moist dentin surface. The adhesive (Single bond) was applied in single layers and light cured. A posterior composite (Filtek Z 250) were used to prepare the bond strength specimens with a 3 mm in diameter bonding area. Control and experimental groups were made with and without application of dye respectively. Each group includes both sound and carious affected dentin. After 24 hour immersion in distilled water, tensile bond strength (MPa) was measured using an Instron testing machine.Results:Analysis of variance (ANOVA) was used to evaluate the data. The tensile bond strength were significantly less in experimental subgroup than control subgroups.Conclusion:The tensile bond strengths were higher in sound and carious affected dentin without application of caries detection dyes.

Bond strength of a universal bonding agent and other contemporary dental adhesives applied on enamel, dentin, composite, and porcelain

“…Considering that dentin is a challenging substrate for adhesion and that the universal SBU is comprised of a heterogeneous composition that mixes various different components into the same solution (e.g., acidic and non-acidic monomers, solvents, fillers, initiators, and silane - Table 1), the combination of these factors may have probably decreased the bonding ability of SBU to dentin. SB, on the other hand, has a less complex composition than SBU, thus allowing satisfactory adhesion, which is corroborated by several previous studies [16][17][18][19]. However, this study tested only the immediate bond strength to dentin, and it is known that etch-and-rinse adhesives tend to generate less stable dentin bonding as compared with self-etch adhesives [8].…”

Bond Strength of Adhesive Luting Agents to Caries-affected Dentin

“…[18][19][20] Even when using proper methods for detecting and removing caries, a heterogeneous substrate can remain after removal of the caries-infected dentin. 21 In some cases, the presence of small sites of CAD surrounded by sound dentin has been observed. Because the sizes and shapes of these sites are often irregular, 22 standardizing the sample preparation for bonding tests is too difficult.…”

Çürük Tespit Boyalarının Çürükten Etkilenmiş Dentine Kompozitlerin Bağlanma Dayanımı Üzerine Etkisi

“…11 Bu materyaller kullanılarak yapılan bağlanma dayanımı çalışmalarında farklı sonuçlar bulunmuştur. [11][12][13] Çalışmalarda sağlam dentin, yapay çürüklü dentin ve bukkal çürüklü dentin yüzeyleri kullanılmıştır. Ancak klinik uygulamalarda okluzal çürüklü dentin yüzeylerine de çürük tespit boyaları uygulanmaktadır.…”

“…Ancak klinik uygulamalarda okluzal çürüklü dentin yüzeylerine de çürük tespit boyaları uygulanmaktadır. 12,13 Literatür incelendiğinde bu ajanların adeziv sistemlerin çürükten etkilenmiş dentine olan bağlanma dayanımı üzerindeki etkileri ile ilgili az sayıda bilgi bulunmaktadır. Bu çalışmanın amacı; üç farklı çürük tespit boyasının bir self-etch adezivin çürükten etkilenmiş dentine olan bağlantısı üzerindeki etkilerini belirlemektir.…”

“…Singh UP ve ark. 12 Caries detector'ün çürükten etkilenmiş ve sağlam dentinde bir total-etch adeziv olan Single Bond'un bağlanma dayanımına olan etkisini bukkal dentin üzerinde araştırmışlardır. Çalışma sonucunda çürük tespit boyasının hem çürükten etkilenmiş dentinde hem de sağlam dentinde bağlanma dayanımını önemli oranda azalttığı görülmüştür.…”
