简要总结

This study will be performed in two parts, in vivo and in vitro to assess the effect of the remineralization potential of self-assembling peptide P11-4 containing Fluoride on caries-affected dentin compared to untreated caries-affected dentin and the influence of Er, Cr: YSGG Laser treatment.

详细描述

The present study will be performed to evaluate the remineralization potential of the self-assembling peptide P11-4 combined with fluoride treatment applied over demineralized dentin in occlusal carious molars.

  • Research objectives: To assess the effect of the two treatment modalities to enhance remineralization of demineralized dentin and clinical performance of restorations.
  • Research question: Will pretreatment of caries affected dentin using self-assembling peptide P11-4 containing fluoride compared to untreated caries-affected dentin will enhance the remineralization and clinical performance of composite restorations In Vitro Study

1- The present study will be performed to evaluate the remineralization potential of the self-assembling peptide P11-4 combined with fluoride and its effect on bond strength and analyze morphological changes over demineralized dentin in occlusal carious molars using Scanning Electron Microscopy (SEM).

  • Research Objectives: To evaluate the effect of Curodont Repair Fluoride Plus and Er,Cr:YSGG laser pretreatment on the bond strength of composite resin to superficial and deep dentin.
  • Research question: Will pretreatment of caries affected dentin using self-assembling peptide P11-4 containing fluoride compared to untreated caries-affected dentin will enhance bond strength?

研究组 & 干预措施

Curodont Repair Fluoride Plus (P11-4 + fluoride)

Experimental

• In the Intervention group the Curodont Repair (P11-4 + fluoride) will be applied according to the manufacturer's instructions: The paste is gently applied to the dentin surface and left undisturbed for 5 minutes to allow self-assembly and infiltration and excess material will be removed with a gentle air spray

干预措施: Curodont Repair Fluoride Plus (Self-assembling peptide remineralization agent)P11-4 peptide, fluoride, mild acidic buffer (pH ~4.5) , Credentis AG, Switzerland (Drug)

干预措施: Beautifil II LS (Drug)

Beautifil II LS

Placebo Comparator

No pretreatment; proceed directly to bonding. Then the surface will dry with absorbent paper. A layer of the adhesive system (BeautiBond extrem, Shofu Inc., Kyoto, Japan) will be actively applied for 20 seconds using a micro brush. Then, the adhesive will light-cure for 10 seconds with Radii-cal LED light curing device (1200 mW/cm2) (SDI, Bayswater, Australia) (2
