Abstract
This study was conducted to compare between conventional silicone-based soft liner and Versacryl lining material for the relining of mandibular complete dentures in flat mandibular cases regarding oral health related quality of life and tissue keratinization index, readings were taken at two weeks, two months and four months.
Twenty-eight patients fulfilling the eligibility criteria were recruited from the out-patient clinic in removable prosthodontics department, faculty of dentistry, Cairo University. The patients were distributed randomly into two groups (fourteen per group) after taking the relining impression for their existing mandibular dentures where; the control group received conventional silicone-based soft liner, while the intervention group received Versacryl lining material.
Results showed a significant improvement in oral health related quality of life in both groups at two weeks, two months and four months. The results showed that Versacryl liner provided a better oral health related quality of life at two weeks and two months than conventional Molloplast-B liner, while at four months there was no difference between the two groups.
This study also showed that there was a remarkable increase in para-keratinization activity with Molloplast-B liner group, while there was a significant increase in TKI over the time in the two groups.
