The purpose of the present study was to investigate an association of acute oral symptom with various climate indices. During the study period, 217 patients visited our hospital with acute periodontal problem. One third of each month was considered as a unit, and the number of patients and climate information in each unit was used for statistical analysis. Significant correlation of the number of patients was observed with mean atmospheric pressure(r=0. 310, p<0. 05) and shining hours(r=0. 369, p<0. 05). These results suggest a possible association of acute oral symptom with climate change.
