Article Synopsis
  • The study aimed to compare the compressive strength of traditional open-faced stainless-steel crowns (OFSSC) with a new type called preformed OFSSC (POFSSC) that uses various restorative materials.
  • A total of 75 3D-printed models were tested, divided into five groups based on the type of crown and restorative material used, followed by rigorous thermocycling and compressive strength testing using Instron.
  • Results showed that the POFSSC with restorative composite (G2) had the highest compressive strength, significantly outperforming the traditional crowns (G1), while the POFSSC with resin-reinforced glass-ionomer (G5) exhibited the lowest strength and the highest failure rate in

The purposes of this study were to evaluate the effect of silver diammine fluoride (SDF) on the shear bond strength (SBS) of pink opaquer (PO) compared to resin-modified glass ionomer (RMGI) and conventional composite (COMP) on demineralized dentin, and also to investigate the mode of failure (MOF). Sixty extracted third molars were prepared, demineralized for 14 days, and divided into four groups: (1) COMP; (2) SDF+PO; (3) SDF+RMGI; and (4) SDF+COMP (restoration size: two by two mm). SBS, MOF, modified adhesive remnant index (MARI), and remnant adhesive volume (RAV) were evaluated using an Instron® machine, light microscopy, 3D digital scanner ( 3Shape©), and GeoMagic Wrap© software.

Most children are able to cooperate during conventional, in-office dental treatment using traditional, communicative behavior guidance techniques that are carefully selected and applied to the developmental needs of a particular child. Children who are unable to cooperate during conventional treatment due to a lack of psychological or emotional maturity and/or the existence of a mental, physical, or medical disability may require pharmacologic techniques such as procedural sedation or general anesthesia to complete rehabilitative dental treatment. Patient safety dictates that careful preparation and robust case selection processes guide clinical decision-making related to pharmacologic behavior guidance.
