“…In addition to that, increased solubility and porous nature of this material are important factors which might promote the potentiality to microleakage. The granulated texture of glass ionomer viewed under the stereomicroscope confirmed its high microleakage scores in a study conducted by Gupta et al 25 Another study by Mali et al 26 also observed maximum microleakage for Fuji II than composite and compomers whereas Walse and Hembree 27 established minimum microleakage with GIC contradicting the results of the present study.…”

Background and objective: Microleakage of restored teeth can be considered as a major contributing factor for the occurrence of tooth discoloration, secondary caries, deterioration of restorative material, postoperative tooth sensitivity, and pulpal irritation. The objective of this study was to compare the microleakage of primary molars restored with conventional glassionomer cement (GIC) and Giomer after caries removal using conventional cavity preparation (CCP) and chemo-mechanical caries removal (CMCR) techniques. Materials and methods:Sixty extracted carious human primary molars were randomly assigned into three groups of 20 each based on the method of caries removal: Group A: CCP technique; group B: CMCR using Papacarie gel; and group C: CMCR using Carisolv gel. Each group was further divided into two of 10 teeth each according to the restorative material used -conventional GIC (Fuji II) and Giomer (Beautifil II). The restored teeth were thermocycled, immersed in methylene blue dye, sectioned, and examined under stereomicroscope to elicit the dye penetration scores. Results:The results demonstrated that none of the restorative materials were free from microleakage. In Fuji II samples highest microleakage scores were noticed in group A (2.09) followed by group B (0.64), and least in group C (0.27), which were statistically significant. However, in Giomer samples no statistical significant difference in microleakage scores was noticed among the three groups. Conclusion:Chemo-mechanical caries removal technique showed less microleakage when compared to CCP technique and the marginal sealing ability of Giomer was superior to conventional GIC.

Objective:This in vitro study evaluated the microleakage of a nano-filled resin-modified glass ionomer and a high viscosity glass-ionomer restorations in class V cavities.Materials and Methods:Thirty-two class V cavities prepared on the buccal and lingual surfaces of 16 sound, third molar teeth were randomly assigned into two groups and restored by one of the glass ionomer material; Group A: A high viscosity (Ketac Molar, 3M ESPE) Group B: A nano-filled resin-modified (Ketac N100, 3M ESPE) glass ionomer. One clinician prepared all the cavities. The materials were used according to the manufacturers’ recommendations. The restored teeth were then stored in distilled water at 37°C for 24 h, thermocycled at 5-55°C for 1000 cycles. The specimens were immersed in aqueous solution of Indian ink dye for 48 h at room temperature. They were embedded in resin polyester and sectioned longitudinally in a buccolingual direction. Microleakage was assessed according to the depth of dye penetration along the restoration. The extent of dye penetration at the occlusal and gingival margins was assessed using a stereo microscope. Randomly selected samples from each group were prepared for scanning electron microscope evaluation. The data were statistically analyzed with Friedman and Wilcoxon signed ranks tests.Results:There were statistically significant differences between the microleakage scores of the two groups for both occlusal and gingival scores (P = 0.001). Occlusal and gingival scores for high viscosity glass ionomer (P = 0.024) and nanoionomer (P = 0.021) using Wilcoxon signed ranks tests showed statistically significant differences. High viscosity glass ionomer showed significantly less microleakage compared to the nano-filled resin-modified glass-ionomer (RMGIs) at occlusal margin (P = 0.001). No significant differences were found between the groups at gingival margin (P = 0.0317).Conclusion:Within the limitations of this in vitro study, nano-filled RMGIs restorations did not perform better than high viscosity glass ionomer in class V cavities in terms of microleakage assessment.

“…However, many studies have indicated that these symptoms are not directly related to the development of secondary caries. The presence of microleakage can lead to the accumulation of bacterial plaque, especially in patients with inadequate oral hygiene and a predisposition to secondary caries development [1,4,7,8,9,10,11,12].…”

ABSTRAKTWstęp: Współczesna stomatologia zachowawcza oparta jest głównie na pracy z materiałami kompozytowymi. Jest to związane nie tylko z możliwością ich kompleksowego zastosowania, ale także z estetycznymi względami, które można osiągnąć dzięki szerokiej gamie tych materiałów. W przypadkach, w których nie jest możliwe prawidłowe wykonanie uzupełnień kompozytowych, należy rozważyć zastąpienie go alternatywnym materiałem, który zapewni bardziej stabilną rekonstrukcję tkanek zęba. Nieprawidłowo wykonane odbudowy kompozytowe w stosunkowo krótkim czasie mogą prowadzić do powstania nieszczelności brzeżnej, co przyczynia się do akumulacji płytki nazębnej i rozwoju próchnicy wtórnej.Celem pracy było dokonanie in vivo oceny przydatności trzech różnych metod diagnostycznych (badania klinicznego, fluorescencji laserowej oraz radiografii) w wykrywaniu próchnicy wtórnej w zębach posiadających wypełnienia amalgamatowe lub kompozytowe w klasie I wg Blacka.Materiały i metody: Badaniem objęto grupę 94 pacjentów w wieku 17–67 lat. Oceniono łącznie 200 wypełnień z materiałów złożonych i amalgamatu, w których stwierdzono obecność nieszczelności brzeżnej, przebarwienie brzegów wypełnienia lub przylegających tkanek zęba. Nie uwzględniano zębów z widocznymi ogniskami próchnicy wtórnej. Przeprowadzono badanie kliniczne, ocenę fluorescencji laserowej oraz badanie radiologiczne zębów zakwalifikowanych do oceny. Wyniki: Obecność próchnicy wtórnej stwierdzono w przypadku 137 spośród 200 badanych zębów. Metoda fluorescencji laserowej i badanie radiologiczne wykazały niską czułość wykrywania próchnicy wtórnej (odpowiednio 0,31 i 0,39). Obydwie metody wykazywały natomiast wyższą swoistość (odpowiednio 0,86 i 0,98) oraz dokładność (odpowiednio 0,49 i 0,58). Wnioski: Badanie kliniczne jest najskuteczniejszą metodą diagnozowania wtórnych ognisk próchnicy w uzupełnieniach klasy I wg Blacka. Fluorescencja laserowa oraz badania radiologiczne powinny być przeprowadzane wyłącznie w ramach uzupełnienia badania klinicznego.
