Abstract

Objective: The aim of this in vivo and invitro study was to compare the effect of conventional and flexible complete denture bases(Polyamide) on microbial adhesion (streptococcus and candida albicans) and the level of secretory immunoglobulin IGA(SIGA). Materials and methods: 10 selected patients were re-habilitated with heat cured mucosa supported complete denture then polyamide flexible denture bases were duplicated. Salivary samples and swaps for microbial adhesion testing were taken. Results: The data was collected and statistically analyzed. Flexible denture bases were less in microbial adhesion on their fitting surfaces than conventional denture bases. The levels of salivary immunoglobulin A (SIGA) are higher in conventional denture bases than in flexible denture bases after 7 days. Conclusion: flexible dentures are more hygienic and biologically compatible than conventional dentures.
