“…[1][2][3]9,16,[19][20][21][22] Morphological and histological considerations, and other clinical factors causing inadequate bonding at the material/tooth surface interface, include cavity configuration (C-factor) and dentinal tubule/enamel rod orientation, capillary movement of dentinal tubular fluids, physical characteristics of the restorative material (filler loading, volumetric expansion, modulus of elasticity and polymerization contraction), inadequate margin adaptation of the restorative material during insertion, inappropriate barrier protection (dental rubber dam), tooth location, occlusal stresses/tooth flexure and patient age considerations. [23][24][25][26][27][28][29][30][31] In this study, since hybrid layer morphology was not evaluated microscopically, the specific nature of restoration failure (microleakage) for each adhesive system is unknown, although several factors were strongly suspected: inefficiency of acidic monomers in alteration of the smear layer for classic hybrid layer formation, cavity C-factor, orientation of dentinal tubules/enamel rods to the cementoenamel junction, use of acetone-based solvent primer systems and post-treatment stresses caused by polymerization contraction.…”

SUMMARYThis in vitro study evaluated the coronal and apical marginal microleakage of four self-etch, seventh generation adhesive systems.Sixty non-carious human molars were randomly assigned to four groups (n=12). Class V cavities were prepared on the facial or lingual surface of each tooth with coronal margins in enamel and apical margins in cementum (dentin) at the cementoenamel junction. The preparations were restored using four self-etch adhesive systems (iBond, G-Bond, Xeno IV and Clearfil S 3 Bond) and a control (no adhesive), followed by insertion of Gradia Direct microfilled hybrid resin composite. The teeth (specimens) were thermocycled 1,000 cycles, immersed in 1% methylene blue dye for 24 hours and invested in acrylic resin. The specimen blocks were then sectioned longitudinally, with dye penetration (microleakage) examined using a 20x binocular microscope. Coronal and apical margins were scored separately for microleakage using a 0-3 ordinal ranking system. Data were analyzed using non-parametric tests at a p<0.05 level of significance. A comparison of adhesive and control groups at the coronal and apical margins revealed that significant (p<.0001) differences were exhibited. At the coronal margin, Xeno IV revealed significantly less leakage than the other adhesives, with Clearfil S 3 Bond exhibiting significantly less leakage at the apical margin. Groups with no adhesive treatment (control) showed significantly greater leakage at both the coronal and apical margin locations. A Wilcoxon signed rank test showed no significant differences at the coronal compared to the apical margins of the four adhesive systems and control tested.

This in vitro study evaluated the effect of two self-etching and three one-bottle bonding systems on microleakage of Class V cavities restored with a resin composite. 50 V-shaped cervical cavities were prepared on each of the buccal surfaces of freshly extracted permanent molars. The cavities were randomly assigned according to used bonding systems: Self-etching bondings; Optibond Solo Plus SE and Prompt-L-Pop and one-bottle bondings; Optibond Solo Plus, Excite and Prime&Bond NT. After applying bonding systems, all cavities were restored with a Charisma resin composite. Restored specimens were stored in distilled water at 37°C for 24 hours. The teeth in each group were thermocycled for 1000 cycles at 5°C and 55°C with a dwell time of 60 seconds, All teeth immersed in 0.5% basic fuchsin dye solution for 24 hours. The teeth then were sectioned in a bucco-palatal/lingual direction and scored on a 0-3 scale at the enamel and gingival margins. Non-parametric statistical analysis of the results showed that there was no significant difference in microleakage between the all bonding adhesives.

“…The study of Santini et al (2004), focused on evaluation of microgaps, showed no significant differences between the use of different types of self-etching agents and the technique of total etching with 36% phosphoric acid. Fabianelli et al (2003) compared marginal leakages between composite materials and hard dental tissues and observed a worse marginal leakage of composite materials in the cervical area copared to occlusion.…”

The aim of the study was to evaluate the marginal microgaps of two light-induced polymerization composite materials: Filtek P60 (3M ESPE) and Opticor New (Spofa Dental) in ovine teeth in vivo.The restorative materials were placed to type A-cavity to buccal surfaces of permanent teeth (Triadan system 301, 302, 303, 401, 402, 403). The variables of composite materials were evaluated in 3 groups of animals, 2 animals in each, at different time intervals (1, 6 and 9 months after beginning of the experiment). In various time intervals, 12 teeth per group were extracted under general injection anaesthesia, 6 teeth from each animal). Altogether 36 teeth were extracted throughout the experiment.During the experiment we observed neither cracks nor marginal discoloration in both Filtek P60 and Opticor New restorations. Retention of all restorations was 100%.Significant (P = 0.029 ANOVA) differences were observed in the dentin with Filtek P60 packable restorations which exhibited smaller marginal microgaps (OPTICOR NEW and dentin 11.09 , FILTEK P60 and dentin 5.64 μ). The ean size of icrogaps between dentin and the packable coposite aterial Filtek P60 was significantly lower (P = 0.029 ANOVA) in comparison with the microhybrid Opticor New composite restorations. These materials are suitable as permanent restoration of dental cervical caries in sheep and other herbivores, such as those kept in zoological gardens and companion animals. Light-cure filling, dentition, histology, restoration, sheep, experimentAt present, veterinary dentistry often deals with the issue of caries. Due to wrong feeding this disease is diagnosed especially in companion animals kept in apartments (Hale 1998;Capík 2007). Caries (caries dentinum) is a disease of hard dental tissues. It is a multifactorial disease (Vaško et al. 1994;Capík 2008). Advanced dental caries may result in indication for dental crown reconstruction using metal materials (Capík 2005). In stomatology practice, different types of restorations are used.The size of arginal leakages between a filling and cavity wall represents an iportant evaluation criterion of filling aterials in clinical stoatology. These icrogaps arise ainly due to a polyerization shock as well as the coefficient of linear theral expansion of the filling and hard dental tissues. In vitro study by Loguercio at al. (2004) evaluated these microleakages. Specimens were thermocycled (500 cycles between 5 to 55 °C, analogous to changes of cold and hot feed and ingestion of liquids) and immersed in 0.5% methylene blue. The packable composites (e.g. Filtek P60) showed lower polymerization shrinkage compared to the hybrid resin. Food as a negative factor of polymerization shrinkage of composites is described by Attin et al. (1995) at the neck area of a tooth by post-operative sensitivity. When comparing the thermal expansion, Pucklett et al. (1995) concluded that classical glass-ionomeric cements have the lowest thermal expansion. The composites, on the other hand, exhibited the highest thermal ex...
