Microfiltration between glass ionomer and composite resin in non-carious class-v injuries
No standards have been established for the treatment of non-carious cervical cavities; a suitable biomaterial will allow good adaptation and longevity of the restoration. Objective: To determine microfiltration in non-carious class V cavities restored with glass ionomer and nanoparticulate resin. Ma...

| Sumario: | No standards have been established for the treatment of non-carious cervical cavities; a suitable biomaterial will allow good adaptation and longevity of the restoration. Objective: To determine microfiltration in non-carious class V cavities restored with glass ionomer and nanoparticulate resin. Materials and methods: Class V cavities made on the vestibular surface of 80 healthy premolars (1.5 mm deep x 3 mm high in the occlusion-gingival direction x 2 mm wide in the mesio-distal direction) were randomly restored with two biomaterials (n = 40): 1) glass ionomer and 2) nano-filled resin. Then, the specimens were isolated with varnish and immersed in methylene blue for 24 hours. Subsequently, the samples were subjected to 500 cycles of thermocycling for 8 hours and 45 minutes with thermal changes of 37°, 72° and 75° C, each cycle with a duration of 17 seconds. The samples were washed with distilled water and sectioned longitudinally to determine the degree of microfiltration using a stereoscope (Leica M60 Biosystems). Categorical data were analyzed with the Chi2 test in SPSS 24®. Results: It was observed that filtration is significantly lower in resin than in those restored with glass ionomers (p < 0.001). However, none of the restoration materials tested were able to seal the margins or walls of the teeth completely. Conclusion: As a result of the present experiment, it is determined that class V restorations sealed with nano-filled resin have less marginal microfiltration than those restored with glass ionomer. |
