SJDC Research & Development wing

SJDC Research & Development wing was established in 2014. The wing initiated incubation center named as “Research Center” in 2021 to foster innovation and research –  oriented culture within the institute.

The center  was involved in synthesis of silver, copper, hydroxyapatite, titanium and zinc oxide nanoparticles. The center has formulated new intracanal medicament using chitosan and calcium hydroxide for disinfection inside root canal. The dentin bonding agent was modified by incorporating antimicrobial monomer along with silica microfillers.

The center has been designed with separate sterilization room, culture preparation room, incubationand culture analysis room. The center has all equipments necessary for culturing of microorganisms, preparation of bacterial inoculum, testing of minimum inhibitory concentration, antibiotic disk diffusion test, serial dilution, incubation of bacteria and enumeration of colony forming units.

PLAGIARISM POLICY

            Checking for plagiarism is essential for maintaining academic integrity, originality, and credibility.

It matters for :

  1. Protecting Intellectual Property
  2. Upholding Academic Standards
  3. Legal & Ethical Consequences
  4. Encouraging Independent Thinking
  5. Ensuring Quality & Accuracy

All academic submissions—including library dissertations, short studies, and research activities—are subjected to plagiarism screening using DrillBit Plagiarism Detection Software.

Once a document is uploaded to the platform, DrillBit analyzes the content against a comprehensive database of academic and online sources. The software generates a detailed similarity report, which includes:

  • The overall percentage of similarity detected in the document.
  • Highlighted sections indicating potential instances of plagiarism.
  • Source links or references for matched content.
  • Recommendations for revision, if applicable.

This process ensures academic integrity and encourages originality in student and faculty research. Documents exceeding the acceptable threshold must be reviewed and revised accordingly before final approval or submission.

According to Dr NTRUHS, plagiarism should not exceed 20% and so, it will be maintained.
