Quantitative Polymerase Chain Reaction Analysis of Cariogenic in Saliva of Oral and Laryngeal Cancer Patients Undergoing Radiotherapy: A Clinical Study.

Context: Radiotherapy leads to radiation-induced caries. There is limited knowledge about the quantification of cariogenic bacteria in the saliva of irradiated cancer patients.

Objective: The aim of this study is to check salivary pH, flow rate, and the assessment of in the saliva of irradiated oral and laryngeal cancer patients using quantitative real-time polymerase chain reaction (qRT-PCR).
