To study the effects of salivary stimulation using chewing gum on oral mucositis (OM) in children undergoing chemotherapy
Patients were randomized to a control group or experimental group. Control patients were given a mouth rinse of nystatin, diphenhydramine, and aluminum three times per day. The test group received the same mouth rinse plus sugar-free chewing gum six times per day for 15 days. The gum was chewed for about 30 minutes.
Prevalence of grade 1 (p < 0.05) and grade 2 (not significant) OM was lower in children who chewed the gum. Grade 3 mucositis was slightly higher among those chewing gum. No difference existed between groups in prevalence of grade 4 mucositis.
Chewing gum for salivary stimulation may help reduce inflammation with low grades of mucositis but shows no overall benefit for more severe mucositis.
Chewing sugar-free gum to increase salivary stimulation is a low-risk intervention that may help in low-grade mucositis cases but appears to have no overall efficacy in reducing the prevalence or severity of mucositis in children receiving chemotherapy. Further research regarding the potential role of salivary stimulation for the prevention or management of OM would be beneficial.
