Abstract
STATEMENT OF PROBLEM
Biofunctional Prosthetic System (BPS) complete dentures have been reported to maintain a harmonious relationship with the surrounding oral structures and provide improved adaptation compared with conventional complete dentures. However, an evaluation of salivary changes and its constituents between BPS and conventional dentures is lacking.
PURPOSE
The purpose of this parallel randomized clinical trial was to evaluate the alpha amylase, cortisol, and pH levels in saliva in participants provided with conventional and BPS complete dentures.
MATERIAL AND METHODS
Sixteen completely edentulous participants were recruited for providing with conventional and BPS dentures (n=8). The levels of alpha amylase, cortisol, and pH in their saliva were evaluated by using an enzyme-linked immunosorbent assay (ELISA), colorimetric, and pH meter before insertion and 1 week and 1 month after denture insertion. The data were analyzed with repeated measure ANOVA and the Student t test (α=.05).
RESULTS
The mean ±standard deviation for pH was 6.94 ±0.22 in conventional complete dentures and 7.04 ±0.12 in BPS dentures; for alpha amylase, it was 206.75 ±14.64 and 210.88 ±15.72 IU/mL; and for cortisol, it was 0.29 ±0.05 and 31 ±0.04 nmol/L before insertion and 1 week and 1 month after denture insertion. From the repeated measures ANOVA, the mean pH and salivary cortisol were not statistically different (P>.05), but salivary amylase was statistically different (P<.05). The Student t test showed no significant difference in pH (P>.05), but a statistically significant difference in alpha amylase and salivary cortisol levels was found between the 2 groups (P<.05).
CONCLUSIONS
No significant difference in salivary pH was found in completely edentulous patients provided with conventional or BPS dentures, but significant differences were found in levels of alpha amylase and salivary cortisol.
