Flow rate, pH and buffer capacity in saliva of adolescents with cerebral palsy

Aim: To evaluate the flow rate, pH and buffer capacity in saliva of adolescents with cerebral palsy (CP). Method: Twenty-four adolescents with CP (14 boys) attending Lar Escola Sao Francisco Rehabilitation Center (age mean±S.D.=12±2) were compared with eighteen adolescents (10 boys) without CP (age mean±S.D.=12±4). The whole saliva was collected under slight suction. Flow rate was calculated in ml/min, and the pH and the buffer capacity were determined using a digital pH meter. The buffer capacity was measured by titration with 0.01 N HCl. Results: Were statistically analysed by Student’s t test. Salivary flow rate, pH and buffer capacity in the pH interval of 6.9–6.0 were significantly lower in individuals with CP (p<0.0001; 0.0063; and 0.0014 respectively). Boys and girls from the cerebral palsy group demonstrated a significantly lower flow rate and buffer capacity in the pH range of 6.9–6.0 than the boys and girls from the control group (p= 0.016; 0.0362; <0.0001; and 0.0003 respectively). The salivary pH was significantly lower in boys with CP (p= 0.0022) while the girls from the same group showed no difference when compared with the control group (p=0.195). Conclusion: That adolescents with CP present lower pH, flow rates and buffer capacity in comparison to the control group, which increases the risk of oral diseases in this population. Key words: Cerebral palsy, saliva, flow rate, pH, buffer capacity, adolescents
