The association between psychological stress and recurrent aphthous stomatitis among medical and dental student cohorts in an educational setup in India

Management of Recurrent Aphthous Stomatitis: An Indian Expert Consensus

Recurrent aphthous stomatitis (RAS) is characterized by painful, oral mucosal ulcers with wide range of prevalence ranging from 2 to 78%. Etiology of RAS is idiopathic and multifactorial. There are numerous gaps in assessment and management of RAS and the absence of guidelines or a consensus document makes the treatment further difficult. The aim of this document is to provide an Indian expert consensus for management of RAS. Experts from different specialties such as Otorhinolaryngology, Oral Medicine/Dentistry and Internal Medicine from India were invited for face to face and online meetings. After a deliberate discussion of current literature, evidence and clinical practice during advisory meetings, experts developed a consensus for management of RAS. We identify that the prevalence of RAS may lie between 2 and 5%. In defining RAS, we advocate three or more recurrences of aphthous ulcers per year as criterion for RAS. Investigation should include basic hematological (complete blood count) and nutritional (serum vitamin B12, and iron studies) parameters. Primary aim of treatment is to reduce the pain, accelerate ulcer healing, reduce the recurrences and improve the quality of life. In treating RAS, initial choice of medications is determined by pain intensity, number and size of ulcers and previous number of recurrences. Topical and systemic agents can be used in combination for effective relief. In conclusion, this consensus will help physicians and may harmonize effective diagnosis and treatment of RAS.

Predisposing Factors for Recurrent Aphthous Stomatitis among Undergraduate Dental Students

Objectives The prevalence of recurrent aphthous stomatitis (RAS) among the general population worldwide is 20%. This study aims to discover any correlations between RAS predisposing factors and the gender and year of study of undergraduate dental students at the Faculty of Dental Medicine at Airlangga University.

Methods A cross-sectional analytical study using simple random sampling was performed. The respondents answered seven questions on a self-reported online questionnaire set up using Google Forms. Chi-square analyses were conducted to determine any correlation between RAS predisposing factors and the gender and year of study of the students.

Results The highest predisposing factors for RAS in undergraduate dental students were local trauma (77.7%) followed by stress (71.3%) and nutritional deficiencies (41.5%). Stress correlated strongly with the year of study (p = 0.015). There was no correlation between gender and RAS predisposing factors (p > 0.05).

Conclusion There was a correlation between stress, one of the predisposing factors for RAS, and the year of study, but there was no correlation between gender and RAS predisposing factors including local trauma, stress, nutritional deficiency, genetics, allergies, and systemic diseases.

Depression symptoms and recurrent aphthous stomatitis-Evidence from a population-based study in Indonesia

OBJECTIVES

This study aims to report the prevalence and distribution of recurrent aphthous stomatitis (RAS) among Indonesian adults and to test the relationship between symptom of depression and RAS.

METHODS

Data from the 2007 Indonesia Family Life Survey (IFLS 2007) were analysed to assess the association between symptom of depression and RAS. The prevalence of RAS in the previous month was self-reported. Symptom of depression was measured using the 10-item Center for Epidemiologic Studies Depression (CES-D) scale. The distribution of RAS according to age, sex and level of stress was also presented in the bivariate analysis. Multivariable logistic regression models were fitted to test associations between symptom of depression and RAS, controlling for age, sex and the stress level.

RESULTS

The previous month prevalence of RAS in Indonesian population was 12%. The adjusted odds ratios (ORs) from the logistic regression models indicate that, for each unit increase in the CES-D depression score (range: 0-30), there was a 9% increase in the odds of having RAS (OR: 1.09, 95%CI: 1.08-1.10). Being older and being male was related with lower prevalence of RAS.

CONCLUSIONS

A higher score of depression was related to a higher prevalence of RAS. This association was persistent even after controlling for age, sex and the level of stress.
