new modality using CO2 modification for treatment of recurrent aphthous ulcer in children

ABSTRACT

The aim of this study was to apply a new modification of CO2 laser for treatment of aphthous ulcer in children. Twenty-four children suffering from RAUs, their age ranging from 5-14 years. The children were divided into two groups. The first group i.e. group I [12 patients] received CO2 laser at 1w power in a focused continuous mode for five minutes after wetting the ulcer with water. The second group [i.e. group II] received CO., laser in the same way but without wetting the ulcer. In both groups the ulcer were measured in mm[2] by a graduated and before laser application, just after application, 3 days after, 7 days after then one month later; and the changes in the size of the ulcer were recorded. Moreover, children were asked to answer questions concerning their pain sensation, eating capability and discomfort and all responses were tabulated. The results showed that CO2 laser application with or without wetting showed immediate pain relief and the child can eat spontaneously after application with no history of recurrence. While those in group I showed better results concerning postoperative oedema than group II
