Özet
In eight edentulous subjects, who had not previously worn dentures, blood flow was measured by Xe-133 clearance after intramucosal injection. Upper and lower complete dentures were then constructed for these subjects, and Xe-133 clearance was measured after the dentures had been worn for 7 and 40 days. Before the insertion of dentures the mean blood flow to palatal mucosa was 18.9 +/- 7.1 ml/100 g/min. Seven and 40 days after wearing dentures the mean flows to the palatal mucosa were 10.6 +/- 4.5 and 12.6 +/- 5.3 ml/100 g/min, respectively. The difference before and after wearing dentures was statistically significant (p < 0.05). The subjects were asked not to wear the dentures for 24 h after the third visit on the 40th day whereupon the blood flow reached almost normal levels (16.2 +/- 5.45 ml/100 g/min). The findings show that wearing dentures hinders the blood supply to the palatal mucosa, and that after resting the oral tissues, blood flow may return to normal levels.
