Abstract
BACKGROUND
Saliva being an important biological fluid of our body contains both specific and nonspecific protective factors which form an integral part of our immune system. Salivary proteins play a substantial role in protecting humans against infection. Their level in oral cavity is subject to constant variations which is dependent on various factors.
PURPOSE
The purpose of the study was to compare the levels of salivary proline-rich proteins (PRPs), glycoproteins, amylase bands, and salivary pH in children with early childhood caries before and after treatment using gel electrophoresis.
MATERIALS AND METHODS
The whole salivary pH, mean protein concentrations, and electrophoretic profiles of the salivary proteins were measured using sodium dodecylsulfate-polyacrylamide gel electrophoresis in both pre- and posttreatment groups. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 15.0 software. Chi-square test and independent t-test were used to further compare the results.
RESULTS
The results were statistically significant in all the groups. There was variation in pre- and posttreatment values seen.
CONCLUSION
Salivary proteins (glycoproteins, PRPs, and amylase) establish an imperative defense mechanism as antimicrobial agents.
