Effect of Liners on Composite Resin Microleakage after Selective Carious Lesion Removal. An experimental Study

Objetive: To evaluate microleakage of composite resins (CR) placed over different cavitary liners after managing deep caries lesions through selective removal soft carious tissue to dentin (SRCT-S). Material and Methods: Fifty four human teeth were collected for testing. Each assay comprised ICDAS 5 or 6 sound controls. Sound prepared with cavities that mirrored the cavities, which SRCT-S. further randomly assigned one three experimental groups: Group A: universal adhesive (UA) + CR, B: glass ionomer cement liner UA C: calcium hydroxide UA+ CR. Occlusal (OM) cervical (CM) was classified within depth categories. ANOVA Chi-square tests computed (p<0.05). Results: OM CM similarly distributed across subgroups (p>0.05). All C samples presented some degree microleakage. However, no statistically significant differences observed between groups each group Conclusion: Teeth restored CR SRCT-S using as a material seem exhibit higher than those alone. Further clinical research is needed deepen these findings. Clinical significance: The application under resin may reduce longevity restoration performing partial tissues. Clinicians should rethink need this application, albeit lack evidence.
