Background- Saliva plays an important part in the maintenance of oral health as it contains many innate and acquired factors with a protective role on the oral tissue. A variety of hormonal changes occur throughout the life of females with a sheer peak during the time of pregnancy. The present study was carried out to determine the changes in flow rate of saliva, ph and buffering capacity in pregnant & non pregnant females. Materials & Methods- The present study comprised of 45 pregnant female and 45 non pregnant females of the same age group. Both stimulated and non stimulated saliva was collected from the patients and was compared. The salivary flow, pH and buffering capacity were measured by GC saliva collection buffer kit. Results- The mean± SD unstimulated flow rate was 5.32 ±1.64 and 4.47±1.45 in non pregnant and pregnant patients. The mean± SD unstimulated salivary flow rate was 9.38±2.15 in pregnant patients and 7.76± 1.75 in non- pregnant patients. The mean pH was 6.20 ± 0.32 and 6.90 ± 0.36 in pregnant and non pregnant patients respectively. The mean buffering capacity was 7.34 ± 1.62 in pregnant females and 10.1 ± 1.40 in non pregnant females. Conclusion- A significant decrease in the flow rate of both stimulated and non stimulated saliva was seen in the present study. pH and buffering capacity of saliva was also less in pregnant females as compared to non pregnant females.
