“…The use of replicas for analysis in the SEM is a technique that has been used for many years (Barnes, ) because it is an effective and precise method already confirmed in the literature (Tomita, Okuda, & Wakumoto, ; Ulusu, Oztaş, & Tulunoğlu, ). Ulusu et al () compared, in their study, the impressions made by the replica technique with the original teeth surfaces in SEM.…”

This study evaluates the bond strength of four self‐etching adhesive systems with different acidity levels in normal and artificially hypermineralized dentin substrate. Healthy human molars were divided into groups: normal dentin—N (n = 36) and artificially hypermineralized dentin—H (n = 36). Self‐etching adhesive systems Clearfil S3 Bond (n = 9), Optibond All in One (n = 9), Clearfil SE Bond (n = 9), and Adhese (n = 9) were used for both the N and H groups. Transparent cylindrical matrices were positioned on the treated dentin surfaces, filled with composite resin, and light‐cured for 40 s. After the transparent cylindrical matrices were removed, the specimens were stored for 24 hr in a humid environment at 37°C and were subjected to a micro‐shear bond strength test. For each group, a specimen was prepared and evaluated in scanning electron microscope for adhesive interface observation. Normality was confirmed and the two‐way analysis of variance and Games–Howell post‐tests were conducted (α = .05). The data demonstrated an interaction between the adhesive system and type of dentin substrate (p < .01). For normal dentin, all adhesive systems assessed were adequate; however, in the hypermineralized dentin, the Clearfil SE Bond two‐step self‐etching adhesive system with mild pH presented the highest immediate bond strength. There was a predominance of adhesive failures for all adhesive systems in the different dentin substrates evaluated. It was concluded that the self‐etching adhesive systems evaluated were efficient for both substrates, and for the hypermineralized dentin, the Clearfil SE Bond presented a higher bond strength value.

“…This method has been used of several impres.sion and model material for the study of restorations including surface combinations for long-term studies following wear, texture and marginal changes and of attrition in segments of the dental arch, plaque formation (1)(2)(3). Other methods and materials have also been employed, and the main purpose has been to study isolated Pilot study parts of a restoration or a tooth surface (4 tron microscopes revealed that both the Ksilicone/epoxy resin and the A-silicone/epoxy resin combinations produced equally good results. The polyether impressions had no advantages over the silicone materials.…”

– In order to obtain a replica technique suitable for a complete or segments of a dental arch two different impression materials were combined with two epoxy resin model materials. The models were examined and photographed in an optical microscope and a scanning electron microscope. No systematic differences were found between the used combinations of materials except a tendency towards greater contraction of one of the model materials. The A‐silicone impression materials combined with one of the epoxy resin material seemed to be the easiest to handle and to give the best models.
