The Thailand-Myanmar border area is a remote area where dental services have difficulty in reaching. Baseline information on oral health status is needed for planning preventive programs. Objectives: The objective of this study was to examine the relationship between salivary factors and dental health status of children in this area. Methods: Four villages along Thailand-Myanmar border at Maesort district, Tak Province, were selected. A cross-sectional study was carried out on 278 children, aged 6-12 years old, attending the Border Patrol Police Schools. DMFT and dmft index, salivary flow rate, calcium concentration, phosphate concentration, fluoride concentration and salivary protein concentration were determined. Salivary protein patterns were also analyzed using SDS-polyacrylamide gel electrophoresis. Results: The results showed that mean dmft of children aged 3-5 years old in this area were rather low (0.72-4.9). The mean DMFT of children age 12 years old were also low (0.25-0.52). Salivary flow rate was in the range of 0.1-2.2 ml/min. Calcium concentrations in saliva found to be in the range of 0.23-0.95 mM. Phosphate concentrations in saliva ranged from 1.21-7.77 mM. Salivary protein concentrations ranged from 1149-4440 mg/l. When these parameters are compared to dental caries status, no value showed statistical significant difference. The SDS-PAGE gel pattern of saliva from the high caries group showed more protein bands than those in the no caries and moderate caries groups, especially in the proteins at the region of 36-40 kDa and 20-26 kDa. Conclusion: the dental health status of children in this remote area of Thailand is rather poor. Salivary protein is the only parameter that showed some relationship to dental status.
