“…This finding agrees with other studies that have concluded that cavity preparations with their margins on enamel produce consistently strong adhesion, while adhesion to dentin proved a challenge due to the greater presence of inorganic structure in enamel than dentin [29,30].…”

Purpose: To compare the degrees of marginal microleakage undergone by different intermediate materials used for provisional restoration in indirect pulp treatment: glass ionomers (Ketac™ Fil Plus (3M ESPE), Ketac™ Molar Easy Mix (3M ESPE), Fuji IX™ GP (GC)) and zinc oxide eugenol. Materials and methods: Twenty young permanent premolars, extracted for orthodontic reasons, were prepared by creating Class II cavities and then divided into four groups according to the material used for pulp capping. The materials were applied following the manufacturers' instructions and stained with methylene blue at 2% to evaluate microleakage. Results: Results were evaluated applying variance analysis (ANOVA). It was found that glass ionomers showed better outcomes than zinc oxide eugenol, with Fuji IX™ GP and Ketac™ Molar Easy Mix producing the best results. Conclusion: For indirect pulp capping, glass ionomer is a favorable material for reducing one of the main causes of treatment failure-microleakagealthough there are differences between brands.

“…It is recommended to store the extracted teeth in distilled water, glutaraldehyde, or thymol solutions for in vitro tests. 15,16 In the present study, the extracted teeth were first disinfected in distilled water containing 1% thymol at room temperature for 24 hours after the tooth extraction, and then kept in distilled water at 37°C for 24 hours following polishing procedure.…”

Objectives The purpose of this in vitro study was to investigate the effects of different disinfection methods on microleakage of Class V Giomer restorations. Materials and Methods Class V cavity preparation was performed on 40 sound permanent central incisors. Class V cavities (3 x 2 x 2 mm) were prepared on the buccal surfaces of the selected teeth. The teeth were randomly divided into four groups, each to be disinfected with a different method: Group 1—Disinfection with 2% chlorhexidine, Group 2—Disinfection with 6% sodium hypochlorite, Group 3—Disinfection with erbium, chromium: yttrium-scandium-gallium-garnet laser, Group 4—Control (distilled water). BeautiBond adhesive and Beautifil II Giomer restoration materials were applied to all surfaces of the cavities after the disinfection of all groups. The teeth were thermocycled 5,000 times (5–55°C), and then were immersed in 0.5% methylene blue for 24 hours. After rinsing, the teeth were longitudinally sectioned and dye penetration was assessed under a stereomicroscope (40x) to evaluate microleakage. Statistical Analysis The results were statistically evaluated by using the Kruskal–Wallis and Mann–Whitney U tests. Results Statistically, no significant difference was found between all four groups (p > 0.05). There was no statistically significant difference in microleakage scores of study groups (p > 0.05). Also, the microleakage scores of the gingival margins were significantly higher than the incisal margins (p < 0.0001). Conclusions Application of the different cavity disinfectants has no effect on the microleakage of Class V Giomer restorations.

“…At 6 months, there was more decline from Alpha level and Charlie level was recorded, but this difference was not statistically significant. Shrinkage stress arises from polymerization reaction of resin containing restorative materials was the main cause of clinical problems like poor marginal adaptation, but Activa contains ionic resin network and bioactive fillers which can further decrease the polymerization shrinkage (26) , in a previous study the polymerization shrinkage stress of Activa was tested and compared with other materials, it was observed that shrinkage stress of Activa was low and no significant differences was found between the tested materials (27) . But in another study the marginal integrity of Activa was evaluated and it was found that the best bond strength outcome for Activa bioactive restorative, occurs when the adhesive was used prior to restoration and the self-adhesive property of Activa is poor (28) .…”

Purpose: compare the chemo-mechanical method of caries removal (CMCR) using Carie-Care™ and conventional technique (Drilling) in normal and disabled Egyptian children. Materials and Method: A total of 40 children were divided into two equal groups .Group A: 20 healthy and normal children. Group B: 20 children with different types of disabilities, either intellectual disability, hearing impairment or visual impairment. Their age ranged from 5-8 years .Two primary carious teeth were chosen in each child according to inclusion criteria (total 80 teeth). The eighty primary teeth from forty children were further subdivided equally into two subgroups (40 teeth in each subgroup) according to caries removal technique. Subgroup Ӏ: caries was removed with CMCR using the Carie-Care system. Subgroup ӀӀ: caries was removed with the conventional drilling technique. Then all teeth were restored with Activa kids bioactive restorative material and followed up at baseline, one month, three months and six months intervals. Results: Results of this study showed that there was no significant difference between patients' groups regarding complete caries removal, total time taken for complete caries removal, pain and patient comfort, but there was a statistically significant difference between both techniques regarding complete caries removal in disabled children group (Group B), and a significant difference was also found in the time taken for complete caries removal , pain and patient comfort in both patients' groups. Also, there was no statistically significant difference between patients' groups regarding the longevity of Activa kids bio-active restorative material at base line, one month, three months and six months follow up periods. Conclusion: Carie-Care™ gel was an efficacious alternative method to treat carious lesions in both normal and children with different disabilities since it allies atraumatic characteristics. Activa kids bioactive restorative material had an excellent performance as a permanent restorative material in vital primary teeth in both normal and disabled children in a period of 6 months.
