Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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?

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

* Group 1 no pretreatment will received.
* Group 2 will receive Curodont Repair (P11-4 plus fluoride).
Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Participants
* Eligible patients will be randomly assigned to the intervention or control group using computer-generated random numbers.
* Allocation concealment will be ensured using sealed opaque envelopes.
* Clinical evaluators assessing outcomes will be blinded to the group allocation to reduce bias.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Curodont Repair Fluoride Plus (P11-4 + fluoride)

• 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

Beautifil II LS

Intervention Type DRUG

Application of Giomer restorative material following standard adhesive procedures without pretreatment.

Beautifil II LS

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
