OBJECTIVE To evaluate unstimulated and stimulated salivary characteristics of 12-13-year-old schoolchildren with and without dental erosion. METHODS The subjects were sixty schoolchildren from 12-13 years old (30 boys and 30 girls) with dental erosion and sixty age- and sex-matched controls. Unstimulated and stimulated whole saliva were collected. Flow rate, pH level, buffering capacity, bicarbonate, buffer base, calcium, phosphorus and urea concentrations of whole saliva were measured. All data were analysed using SPSS 13.0. RESULTS The flow rate, pH, bicarbonate, buffer base, calcium, phosphorus, and urea of unstimulated and stimulated saliva did not differ significantly between the dental erosion group and the control group (P>0.05). The stimulated salivary buffering capacity did not vary between the two groups (Fisher's exact test, P>0.05). CONCLUSIONS The salivary characteristics are similar amongst 12-13-year-old schoolchildren with and without dental erosion in Southern China.

D010812	Physical Stimulation	Act of eliciting a response from a person or organism through physical contact.	Stimulation, Physical,Physical Stimulations,Stimulations, Physical
D002021	Buffers	A chemical system that functions to control the levels of specific ions in solution. When the level of hydrogen ion in solution is controlled the system is called a pH buffer.	Buffer
D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
