Preservation in Young Patients of Pulp Vitality and Anatomical-Functional Restoration of the Lost Structure.

Often, young patients (≤30 years old) present with carious lesions that progress acutely, compromising a large amount of tooth structure. In these cases, a treatment to prevent the occurrence of pulp exposure and promote remineralization of caries-affected dentin is necessary to maintain healthy dental structure and allow more conservative interventions. The approach will be different when pulp exposure occurs: The therapeutic treatments will be focused on reparative dentin formation and prevention of microorganisms penetrating the pulp organ.

Effect of resin-modified glass-ionomer cement lining and composite layering technique on the adhesive interface of lateral wall.

Unlabelled: Interface integrity can be maintained by setting the composite in a layering technique and using liners.

Objective: The aim of this in vitro study was to verify the effect of resin-modified glass-ionomer cement (RMGIC) lining and composite layering technique on the bond strength of the dentin/resin adhesive interface of lateral walls of occlusal restorations.

Material And Methods: Occlusal cavities were prepared in 52 extracted sound human molars, randomly assigned into 4 groups: Group 2H (control) - no lining + two horizontal layers; Group 4O: no lining + four oblique layers; Group V-2H: RMGIC lining (Vitrebond) + two horizontal layers; and Group V-4O: RMGIC lining (Vitrebond) + four oblique layers.
