Background: Complete denture help to re-establish the occlusion and aesthetic to such extent it mimic the
previously missing teeth and other features which may be lose over the time. In a complete denture wearer,
saliva is responsible for the retention of the prosthesis due to its lubricating function. It also aid in integrity,
adhesion and stabilisation of dentures in position after the placement. It act as interposed salivary film which
allowed the prosthesis to lie on the film rather than on the bare mucosa. This would help to protect the tissues
from the hydration and forces of the denture base that acting on it. Therefore, maintaining normal pH and
salivary flow rate is required, in order to achieve a better retention of denture as well as good oral health.
Aim: To investigate the relationship between the salivary flow rate before and after the placement of
complete denture.
Materials and Method: There were 15 participants in the age group of 55 to 70 years old, which required
complete denture prosthesis for the first time. The unstimulated or resting whole saliva and stimulated
whole saliva was collected by using spitting method. Saliva production was stimulated by chewing paraffin
wax. The time taken for saliva collection of 5 mL was recorded by using stopwatch. The data obtained was
analysed by using paired t-test.
Results: There was significant difference between the unstimulated whole salivary flow rate and stimulated
whole salivary flow rate before the placement of the denture, which was by 0.20 mL/min. Whereas, the
difference between the unstimulated whole salivary flow rate and stimulated whole salivary flow rate after
the placement also show significant changes which was about 0.14 mL/min. Chewing of paraffin wax as
well as placement of denture act as stimulatory agents in production of saliva.
Conclusion: Stimulated salivary flow rate were higher than the unstimulated salivary flow rate which
obtained before and immediately after the placement of complete denture. There was significant differences
of the salivary flow rate before and after the placement of denture.
