A Simplified Culture for the Diagnosis of Denture Stomatitis

The relationship between the clinical features of denture stomatitis and the number of Candida colonies determined by swabs from the palatal mucosa has been proved to be close. In daily practice, if the number of Candida organisms can be assessed present without both difficulty and need for special equipment, it might be of benefit. Therefore, a simplified culture has been developed for the diagnosis of denture stomatitis in the dental office, which is based on the acid-producing capacity of Candida species and is displayed in color changes. The coefficient of correlation between the culture reaction and the clinical assessment of denture stomatitis was r=-0.64 ~ -0.86. It has also been helpful in instructing patients about denture cleanliness.Stomastat® (Sankin Industry Co. Ltd., Osaka, Japan) and Candida Yellow Medium® (Fujiseiyakukogyo Co. Ltd., Tokyo, Japan) on the market are based on this research

Clinical Effect of Infusion Therapy in Combination with Local Antimycotic Drugs on Acute Pseudomembraneous Candidiasis Induced by Removable Dentures

Denture stomatitis is often observed in the denture-bearing mucosa. Candida albicans and related species are now believed to play a major role as a pathogenic factor in denture stomatitis. If systemic predisposing factors are present, denture stomatitis will sometimes develop into acute pseudomembraneous candidiasis. In acute pseudomembraneous candidiasis, the patients cannot take foods, and dehydration often occurs. This vicious cycle is the most important cause of increase in the growth of Candida species. Therefore, in order to improve the patient's physical condition, infusion therapy will be the first choice of treatment. The purpose of this study was to investigate the clinical effect of infusion therapy in combination with local antimycotic drugs on this type of candidiasis. We observed 4 cases of acute pseudomembraneous candidiasis induced by removable dentures and tried to treat these patients with infusion therapy (5% dextrose in lactatedRinger's solution) and local antimycotic drugs (Nystatin ointment or 1 % Miconazole nitrate cream). The acute inflammatory symptoms were significantly decreased by this therapy. The result of this study indicated that infusion therapy in combination with local antimycotic drugs was clinicaly effective on acute pseudomembraneous candidiasis induced by Candida-induced denture stomatitis

Metal Hypersensitivity in Dentists : a Patch Test Study

Patch test of dental alloys was conducted on dentists in the Department of Prosthetic Dentistry, Hiroshima University School of Dentistry. The positive rate of the first patch test in the test group was 47.1 %, and that in the control group was 10.0%, showing a large difference between the two groups. Furthermore, a second patch test was conducted on those who showed a positive response together with pustular or follicular reaction. As neither positive response nor pustular or follicular reaction was observed in the second patch test, the results were regarded as negative. Only a very slight difference in the positive rate could be observed when the results of the two tests were combined. The results of the present study suggest that the possibility is small for dentists to develop metal hypersensitivity in normal clinical practice

Interoceptive accuracy is related to the psychological mechanisms of the burning mouth syndrome: a cross-sectional study

Abstract Background Different perspectives are needed to understand the pathophysiology of burning mouth syndrome (BMS), including physiological and psychological standpoints. The significance of interoception in chronic pain has been suggested. However, few studies have investigated this relationship in BMS. Therefore, we examined the role of interoception in BMS. Methods This is a cross-sectional study. BMS patients (N = 64) participated in the study. We used interoceptive accuracy (IAc) based on the heartbeat counting task. Then, participants were divided into high and low IAc groups, and their scores on clinical assessment including pain and psychological evaluation were compared. Results The Visual Analogue Scale scores indicating pain in low IAc patients, but not high IAc patients, were positively correlated with the Beck Depression Inventory-Second Edition (BDI-II) and the State-Trait Anxiety Inventory-State (STAI-S) Scores. Conclusions Interoception might play a role in the pathophysiology of BMS
