Abstract
Introduction Despite the decrease in the prevalence of dental caries globally, its impact on children can be life threatening. These impacts have been found to constitute health problems which affect their quality of life. 2 Saliva plays an important role in protecting the teeth from dental caries. Aim To compare the flow rate and buffering capacity of saliva in dental caries active and caries free subjects. Design A comparative study that included a representative samples of one hundred and sixty healthy children who were selected from 10 public primary schools in Ibadan and were divided into 80 caries active group and 80 caries free group. Unstimulated saliva samples were collected inside a graduated measuring tube fitted into a funnel over a period of 5minutes by spitting and salivary flow rates were measured. Buffering capacity of each saliva sample was determined by titration of 3ml of 0.005 mol/L hydrochloric acid (HCL) solution with 1ml of saliva, and the buffering was measured using a pH meter. The data was statistically analysed using student t test, ANOVA and Turkey’s HSD Posthoc test. Result Mean ±SD age of study participants was 9.6 (2.6) years. The mean ±SD DMFT/dmft of age 6-8 years and 9-12 years were 0.6±0.10/1.54±1.84 and 1.21±1.53/1.09±1.23 respectively. The mean ±SD salivary flow rate and salivary buffering capacity were 1.0±0.5mls/min and pH 6.3±0.7. Caries free participants had highest mean SFR(1.1±0.5mls/min) and SBC (pH 6.4±0.6) respectively. The majority (70.6%) and 77.6% of the participants had SFR greater than 0.7mls/min and SBC greater than pH> 6.0 respectively. A steady and slight reduction in the mean SFR and SBC was observed as the DMFT/dmft increases (p>0.05). In conclusion, the study demonstrated lower salivary flow rate and salivary buffering capacity among caries active participants when compared to caries free participants.
