Comparison of the onset time of oral mucositis
mucositis
MUCOSITIS, ORAL MUCOSITIS
As the exposure dose was increased in the radiotherapy, the cumulative incidence of Grade 2 and 3 oral mucositis gradually increased in the patients of the two groups (as shown in Figure Cumulative incidence of Grade 2 mucositis in the night and day groups during radiotherapy.Cumulative incidence of Grade 3 mucositis in the night and day groups during radiotherapy.The mean value of radiotherapy for the patients to develop Grade 2 oral mucositis was 15.67 ± 5.05 and 20.92 ± 6.21 in the night group and the day group, respectively. Compared with the night group, the patients needed more exposure to develop Grade 2 oral mucositis in the day group, which also meant that the time to develop Grade 2 oral mucositis was significantly delayed for the day group. Their difference was statistically significant (
