Immunological status of patients with denture stomatitis and yeast infection after treatment of maxillofacial tumors.

Therapeutic modalities employed in the treatment of maxillofacial malignancy, tumor resection, radiation and chemotherapy, can result in local and systemic changes in healthy oral tissues many years after anticancer therapy has been stopped. The immunologic status of a select group of nine individuals who underwent surgery of the maxillofacial region and after head and neck irradiation, with severe and persistent denture stomatitis was studied. A significant impairment of granulocyte and lymphocyte functions and increased concentrations of serum IgG, as compared to healthy controls, were found in the patients of the study group. It is concluded, that this group of patients show immunological abnormalities many years post therapy, which must be recognized by the clinician in order to effect a cure.

Sensitivity of the replica method in the detection of candidal infection among denture wearers with clinically healthy oral mucosa.

To ascertain the role of Candida in denture stomatitis, the practitioner must conduct a mycologic examination of the acrylic resin denture surface, because it acts as a reservoir for continuous reinfection of the palate. Twenty-two patients were examined to compare the sensitivity of the standard technique of swabbing the denture to that of a newly developed cast agar replica technique for detecting Candida albicans. The dentures were swabbed and cast replicas of the tissue-fitting surface of the dentures were made of both study populations. The majority of cultures obtained by swabbing failed to detect the presence of Candida albicans, while all cast agar replicas grew Candida albicans. The replica method for the detection of Candida albicans in edentulous patients seemed to be a more sensitive method than currently available mycologic methods.
