“…Various studies are available comparing various resin adhesive systems and their shear bond strength and microleakage as well as the effect of enamel wetness on bonding agents [22][23][24]. Bertoz et al in their study concluded that the best condition for the application of primers to dental enamel occurs in the absence of moisture [25].…”

Background. The quantity and quality of the etching pattern produced by acids play a significant role in the wettability and contact angle of the adhesive with the enamel surface in orthodontics. The better the etch pattern, the more the surface energy of the enamel, better the penetration of the adhesive, which ultimately results in better bond strength. The present study aimed to evaluate the contact angle of the bonding agent with the enamel surface etched by five commercially available etchants and check if any difference existed between the five. Materials and Methods. Twenty-five human maxillary and mandibular central incisors and premolars extracted for orthodontic or dental purposes were used in this study as samples. The teeth were allocated into five groups based upon the etchant used to etch the enamel surface. After the samples were etched, a hard tissue microtome was used to create thin slices of the enamel surface. The samples were then exposed to bonding agent Ormco Enlight. The bonding agent was released in the form of droplets onto the enamel slices mounted on a contact angle goniometer. The contact angle values were tabulated, and statistical analysis using the one-way ANOVA test was carried out. Results. The contact angle measurements of the etchant group, DPI, were the lowest, while D-tech has the highest contact angle values. However, statistical analysis revealed no statistically significant difference between the contact angle measurements of the five groups included in the study. Conclusion. No statistically significant difference existed between the five etchant groups included in the study. However, commercially available etchant DPI showed lesser contact angle and thus better wettability in comparison to other groups. Further elemental analysis and surface analysis are required to validate these results.

Objective: To evaluate micro shear bond strength of different adhesives in hypomineralized primary teeth enamel. Material and methods: A total of Thirty-five primary maxillary and mandibular molars were made in to 115 sections were preserved in 10% neutral buffered formalin at room temperature until sample preparation and utilized for the study. after discarding of 15 broken samples, 110 sections were utilized and divided in to four groups, control enamel group [with group I (N=25) and group II (N=25)] and hypomineralized enamel group [with group III (N=25) and group IV (N=25)]. The teeth samples were color coded and mounted in the acrylic block. Teeth were positioned horizontally and faced a wet 600-grit silicon carbide finishing paper to provide flat enamel surfaces with a 2 to 3 mm diameter surface roughness and shear bond strength was tested using Universal Testing Machine. The fractured surfaces were evaluated for failure modes using light microscopy. Result: The bond strength of G-Premio bond is 21.56±6.72 MPa in control enamel and 12.8±1.52 MPa in hypo mineralized enamel. There exists a significant bond strength difference between both the adhesives to hypomineralized enamel (GC SOLARE universal bond= 7.07±3.90 MPa vs G- PREMIO bond 12.8±1.52 MPa; P≤.001). The most common failure is the cohesive failure Conclusion: The present study indicates that the overall bonding of both adhesives to hypomineralized tooth is less effective than bonding to “normal” enamel. However, the shear bond strength of G-Premio bond to control enamel and hypomineralized enamel is significantly greater than GC Solare Universal Bond. Clinical relevance: Restorative care of teeth with hypomineralization is difficult, and treatment decisions are influenced by a variety of factors including the severity of the disease, compliance and adhesive properties of the materials used and This is the first study to look at how self-etching adhesives affect hypomineralized primary enamel and helps in bonding strength of the affected enamel and based on this study results the bond strength of GP bond to control enamel and hypomineralized enamel is significantly greater than GC Bond.
