METHODOLOGY: Data was collected for this cross-sectional study between August 2020 and January 2021 from 11-to-23 years old participants in 43-countries using an electronic validated questionnaire developed in five languages. Data collected included information on the dependent variables (the presence of oral conditions- gingival inflammation, dry mouth, change in taste and oral ulcers), independent variable (COVID-19 infection) and confounders (age, sex, history of medical problems and parents' educational level). Multilevel binary logistic regression was used for analysis.
RESULTS: Complete data were available for 7164 AYA, with 7.5% reporting a history of COVID-19 infection. A significantly higher percentage of participants with a history of COVID-19 infection than those without COVID-19 infection reported having dry mouth (10.6% vs 7.3%, AOR = 1.31) and taste changes (11.1% vs 2.7%, AOR = 4.11). There was a significant effect modification in the association between COVID-19 infection and the presence of dry mouth and change in taste by age and sex (P = 0.02 and
OBJECTIVES: The aim of this study was to assess the self-reported presence of oral lesions by COVID-19-infected young adults and the differences in the association between oral lesions and COVID-19 infection in smokers and non-smokers.
METHODS: This cross-sectional multi-country study recruited 18-to-23-year-old adults. A validated questionnaire was used to collect data on COVID-19-infection status, smoking and the presence of oral lesions (dry mouth, change in taste, and others) using an online platform. Multi-level logistic regression was used to assess the associations between the oral lesions and COVID-19 infection; the modifying effect of smoking on the associations.
RESULTS: Data was available from 5,342 respondents from 43 countries. Of these, 8.1% reported COVID-19-infection, 42.7% had oral manifestations and 12.3% were smokers. A significantly greater percentage of participants with COVID-19-infection reported dry mouth and change in taste than non-infected participants. Dry mouth (AOR=, 9=xxx) and changed taste (AOR=, 9=xxx) were associated with COVID-19- infection. The association between COVID-19-infection and dry mouth was stronger among smokers than non-smokers (AOR = 1.26 and 1.03, p = 0.09) while the association with change in taste was stronger among non-smokers (AOR = 1.22 and 1.13, p = 0.86).
CONCLUSION: Dry mouth and changed taste may be used as an indicator for COVID-19 infection in low COVID-19-testing environments. Smoking may modify the association between some oral lesions and COVID-19-infection.
METHODS: Systematic searches were conducted on 6 databases (English and Chinese). Studies published up till May 2017 were considered for inclusion.
RESULTS: A final 14 RCTs (total 994 head and neck cancer patients undergoing radiotherapy) compared Chinese herbs with no herbs, were included in analysis. Very low to moderate quality of evidence found Chinese herbal treatment may relief radiotherapy-induced xerostomia and other related complications (such as oral mucositis and loss of appetite) in head and neck cancer patients.
CONCLUSION: There is limited evidence that Chinese herbal treatment may relief radiotherapy-induced xerostomia and other related complications in head and neck cancer patients.
Methods: We included patients with histopathologically diagnosed head and neck cancers who had received radiation, with an Eastern Cooperative Oncology Group (ECOG) performance status 0-1 and age range of 15-60 years. Patients with prior radiotherapy and chemotherapy, edentulous status, total parotidectomy, sicca syndrome or on xerosis-induced medications were excluded. We assigned 15 patients each to the Oral7® and salt-soda groups.
Results: There was no significant difference in the mean Decayed, Missing and Filling Teeth (DMFT) score between groups. Head and neck cancer patients who were on Oral7® had a significantly better quality of life than those on salt-soda in relation to the swallowing problems, social eating, mouth opening, xerostomia and illness scales. Patients who were on Oral7® had a significantly lower xerostomia score than patients on salt-soda mouthwash. Patients on Oral7® had a significantly lower mucositis score in week 5-7 compared to patients in the salt-soda group.
Conclusion: Oral7® showed advantages over salt-soda solution in relation to reducing xerostomia, easing radiation-induced mucositis, and improving quality of life, despite the non-significant difference in the dental caries assessment.
METHODS: Head and neck cancer patients were recruited from July 2016 till March 2017 at National Cancer Institute, Ministry of Health, Malaysia. All study participants continued their standard oncology surveillance. Treatment group participants additionally received Chinese herbal treatment. The assessments included unstimulated salivary flow rate (USFR), stimulated salivary flow rate (SSFR), and QoL questionnaire.
RESULTS: Of 42 recruited participants, 28 were in the treatment group and 14 were in the control group. Participants were mainly Chinese (71.4%), stage III cancer (40.5%), and had nasopharynx cancer (76.2%). The commonly used single herbs were Wu Mei, San Qi, and Tian Hua Fen. Sha Shen Mai Dong Tang, Liu Wei Di Huang Wan, and Gan Lu Yin were the frequently prescribed herbal formulas. The baseline characteristics, USFR, SSFR, and QoL between control and treatment groups were comparable (p > 0.05). USFR between control and treatment groups were similar throughout the 6-month study period. SSFR for the treatment group significantly improved from 0.15 ± 0.28 ml/min (baseline) to 0.32 ± 0.22 ml/min (p = 0.04; at the 3rd month) and subsequently achieved 0.46 ± 0.23 ml/min (p = 0.001; at the 6th month). The treatment group had better QoL in terms of speech (p = 0.005), eating (p = 0.02), and head and neck pain (p = 0.04) at the 6th month.
CONCLUSION: Herbal treatment may improve xerostomia and QoL in post-radiotherapy head and cancer patients.
