The Impact of Palatal Rugae Addition to Complete Dentures on Patients' Satisfaction and Oral Health Related Quality of Life

"Participants were randomly allocated into two intervention sequences using a computer-generated randomization list. The two sequences were:~* Group A: Received maxillary complete denture with palatal rugae first, followed by a smooth polished palatal surface denture after a 2-month adaptation period.~* Group B: Received a smooth polished palatal surface denture first, followed by a rugae-enhanced denture after a 2-month adaptation period."
