Abstract

Molecular techniques—DNA/RNA extraction, PCR amplification, qRT-PCR, DNA sequencing—enable mechanistic study of oral disease and host response. This note outlines core molecular methods, their application to oral tissues and biofilms, and how transcript and gene-expression profiling illuminate inflammatory pathways in caries and periodontitis. Proper sample handling, primer design, and platform choice determine data quality and biological interpretation.
