Sir, further to the letter on denture ulcerations (BDJ 2008; 205: 297) it comes to mind how simple measures can control multifarious causes of oral ulcers, especially the more common ones such as denture sore mouth. Betamethasone mouthwash is one of the widely prescribed mouthwashes in such cases. As the authors correctly point out, monomer leaching is not a very common cause of symptoms in such a patient and we would like to add the importance of taking an oral swab for culture of any possible fungal organisms in such cases as these micro-organisms are of prime importance in sore denture mouths. Subsequent to this, it might be appropriate to prescribe miconazole gel or nystatin pastilles to such patients for symptomatic relief.
