The present study plan to assess the salivary pH at the commencing of prosthodontic or orthodontic treatment and after two weeks, six weeks , and fourteen weeks. It was hypothesized that the PH values between the starting time and these follow up intervals was not significant.
30 patients were included in this study who are allready attend to commence prosthodontic and fixed orthodontic treatment. 20 patients were stating to wear orthodontic appliance while the remaining patients comenced to be rehabilitated by prosthodontic treatment. All the subjects based on inclusion and exclusion criteria. Saliva specimen were got from all subjects, instantly previous to the insertion of aplince or denture (T0; baseline evaluation), after two weeks (T1), six weeks (T2), and fourteen weeks (T3) from the baseline assessment. The pH values were measured with the GC Saliva-Check Kit (GC Corp., Leuven, Belgium). Univariate (ONE WAY ANOVA) test was used, and differences within groups were inspected by using multiple comparison method (L.S.D.). The salivary samples at different time intervals present a signifigant difference of the PH value, between each succeeding time periods, and also from the base line time T0
In conclusion, when the results of the present study is displayed, the hypothesis is rejected due to a significant difference was observed in PH value between the baseline salivary PH and the succeeding follow up periods.
