“…Previous investigations had conflicting conclusions with respect to changes in saliva composition after the insertion of new dentures. Bhat et al [ 7 ] found decreased pH salivary levels, whereas Nikolopoulou and Tzortzopoulou [ 9 ] observed higher pH values 15 days after the insertion of either conventional or implant-supported dentures. In our study, there were no significant differences of pH throughout the period under evaluation ( p = 0.172) and this finding is in agreement with Mäkilä [ 21 ].…”

“…During the first days after insertion of new dentures, sore spots or injured mucosa are commonly observed. Some studies report changes in saliva composition during this period, particularly the concentration of acid uric and pH levels [ 8 , 9 ]. However, it is still unclear if these changes have an impact on the patient's adaptation to the denture and which salivary components play a relevant role in this process.…”

Objective. To assess changes in levels of salivary nitric oxide (NO) after insertion of new complete dentures and its association with clinical and salivary parameters. Methods. Nineteen fully edentulous subjects were included, mean age 64.4. Unstimulated whole saliva was collected before and after insertion of the dentures, at follow-up visits, and after 12 months. The concentration of the final stable NO product (nitrite) was measured by a colorimetric assay based on the Griess reaction. Clinical parameters were assessed during all clinical visits. Results. Functional adaptation to the dentures progressively improved, with no complaints at the long-term follow-up. NO concentration was not influenced by the level of functional adaptation, presence of injuries to the mucosa, salivary flow, and saliva viscosity. Pairwise comparison showed a reduction in NO concentration at the first follow-up compared to baseline values but differences were not statistically significant. Significant differences were observed in NO concentrations at the long-term follow-up when compared to the first (p = 0.024) and second (p = 0.027) visits. Conclusion. NO concentration reduced after denture insertion and returned to baseline levels in the long-term follow-up. This appears to be an autonomic response of the body and provides valuable complementary information for the management of the edentulous patient.

“…We observed that mean pH of saliva before denture insertion was 6.7 and after denture insertion was 5.1. Nikoloupoulo et al [11] determined changes of pH of resting saliva before and after prosthetic treatment in implant denture wearers. The study sample comprised 2 groups of edentulous patients, ranging in age from 50 to 80, who had not worn complete dentures in the past.…”

Background: Many factors influence the composition of saliva. The rate of secretion follows a circadian rhythm, decreasing during sleep and increasing during day. The present study was conducted to assess pH level and uric acid in saliva before and after complete denture insertion. Materials & Methods: 80 completely edentulous patients of both genders were divided into two groups of 40 each and each group was further divided into two groups of 20 each. Group I was age ranged 40-60 years contains two subgroups: group A1 for smokers and group A2 for non-smokers. Group II age ranged 61-80 years contains two subgroups: group B1 for smokers and group B2 for non-smokers. Saliva samples were collected from subjects immediately before the insertion of dentures and pH & uric acid estimation was done. Results: Out of 80 patients, males were 45 and females were 35. The mean pH of saliva before denture insertion was 6.7 and after denture insertion was 5.1. The difference was significant (P< 0.05). The mean uric of saliva before denture insertion was 4.5 and after denture insertion was 3.7. The difference was significant (P< 0.05). There was significant difference in pH and uric acid level while comparing A1 vs A2 and B1 vs B2 (P< 0.05). Conclusion:There was no significant decrease in levels of salivary pH and uric acid in complete denture wearer.

“…Thus, when more mastication was needed, significant changes have been observed in the salivary flow rate with consequent changes in amylase and protein concentration, as well as an increase of pH values respectively [21]. In addition to that, another study reported a statistical significance of pH values before and after the CDs insertion [22]. Others, however, have not found significant changes in pH values [4,23].…”
