Background: Local adverse events associated with inhaled corticosteroid use, including dysphonia, pharyngitis and oral candidiasis, can affect adherence for treatment. 'Mouth rinsing method' has been used for reducing local adverse events, but it cannot ensure complete prevention. The goal of this pilot study was to identify whether the 'immediate diet method' can reduce local adverse events in a limited number of patients. Methods: The study was conducted in a total of 98 patients, who had been prescribed a medium-dose fluticasone propionate for the first time, from January to October in 2010. One training nurse had performed the education on how to use the inhaler, including the mouth rinsing method. And with follow-ups at one month intervals, any patient who experienced such adverse events were educated on the immediate diet method, having a meal within 5 minutes after using an inhaler and they were checked on any incurrence of adverse events with one month intervals for 2 months. Results: The mean age of patients was 65.9 years old. The local adverse events had incurred from 18.4% of the study subjects. When performed the follow-up observation in 18 patients with local adverse events after education on the immediate diet method, 14 patients (77.8%) had shown symptomatic improvements. Three of 4 patients did not show any improvement, in spite of implementing the immediate diet method. The other 1 patient did not practice the immediate diet method properly. Conclusion: The immediate diet method may be useful in reducing the local adverse events, caused by the use of inhaled corticosteroid.

Burning mouth syndrome (BMS) is defined as burning pain in the tongue or other oral mucous membrane associated with normal sign and laboratory findings at least 4 to 6 months. There are many factors that affect this condition and the pain characters are various among the sufferers, so it is difficult to diagnose exactly and treat properly. The cause of BMS is currently unknown. The etiology is presumed to be that it is related with local, systemic and psychogenic factor. The BMS is related with local factor such as allergic reaction, oral fungal infection(candidiasis), parafunctional oral habits and systemic factors such as diabetes mellitus, hypothyroidism, nutritional deficiencies(vitamin $B_{12}$, folic acid), hyposalivation and psychogenic factor such as depression, anxiety, cancerphobia. So clinicians must be aware of these factors and can give proper treatment options to patients. The management of BMS are pharmacologic management, cognitive behavioral therapy and psychotherapy treatment. Clonazepam, gabapentin, amitriptyline, alpha-lipoic acid and capsaicin are used to manage the BMS. Among these, topical clonazepam is reported that the effect is higher than systemic medication and the complications are rare. This case report is about some cases of the effect of topical clonazepam on BMS.

Phytoncide, essential oil of trees, has microbicidal, insecticidal, acaricidal, and deodorizing effect. The present study was performed to examine the effect of phytoncide on Candida albicans, which is a commensal colonizer of the mucous membranes but has become an opportunistic pathogen. C. albicans was incubated with or without phytoncide extracted from Hinoki (Chamaecyparis obtusa Sieb. et Zucc.; Japanese cypress) and then changes were observed in its optical density, cell viability and morphology. As concentrations of phytoncide added to the culture medium increased, optical density and cell viability of C. albicans decreased. Minimum inhibitory concentration of phytoncide for C. albicans was observed to be 0.25%, and minimum fungicidal concentration was 0.5%. Numbers of morphologically atypical cells with electron-dense cytoplasm and granules and increased with increasing concentration of the phytoncide. At higher concentrations of phytoncide, compartments and organelles in the cytoplasm became indistinguishable. The overall results indicate that the phytoncide used for this study has a strong antimicrobial activity against C. albicans. Therefore, the phytoncide may be used as a candidate for prevention and therapeutic agent against oral candidiasis.

Xerostomia is subjective feeling of dry mouth, a symptom that may or may not be accompanied by hyposalivation, an objective decrease in salivary flow. There are many causes induced xerostomia like drugs, salivary gland diseases, radiation therapy to the head and neck region, Sjogren syndrome, emotional stress etc. Insufficient salivary flow creates complications with oral candidiasis, dental caries, periodontitis, halitosis, dysgeusia. So finally, these complications lead to an overall decline in quality of life. Managements of xerostomia are eliminating or alterating the etiologic factors, relieving symptoms, preventing or correcting the consequences of salivary dysfunction, treating underlying disease and stimulating salivation. One of the salivation stimulation agents studied to treat xerostomia was the pilocarpine muscarinic agonist. Pilocarpine is one of salivation stimulants, a parasympathomimetic drug and non-selective muscarinic receptor agonist. Systemic pilocarpine has been used to stimulate salivary secretion. But systemic administration of pilocarpine has limitations such as increased risk of side effects and contraindications. Side effects of systemic pilocarpine administration are sweating, urinary and gastrointestinal disturbance, risk of cardiovascular and pulmonary disorders. This drug must be used carefully by patients with controlled asthma, chronic bronchitis, pulmonary or cardiac disease. Patient with acute asthma, narrow angle glaucoma, iritis should not use pilocarpine. Like this, systemic pilocarpine has many limitations. So, many investigators also have looked at the effectiveness of topical pilocarpine. Here we present patients with xerostomia which was relieved by pilocarpine mouthwash.

Propolis is an extremely safe natural antimicrobial substance that has been reported to have powerful antibacterial efficacy. The aim of this study was to evaluate the inhibitory effects of propolis against Candida albicans (C. albicans). Propolis was collected from the honey bee Apis mellifera. The strain of C. albicans was cultivated overnight in liquid media incubated at $37^{\circ}C$. The antimicrobial activity was investigated using phosphate buffered saline (PBS), 3% sodium hypochlorite (NaOCl), 0.1% chorhexidine (CHX), and propolis extracts ($5{\mu}l/ml$, $10{\mu}l/ml$). C. albicans were sensitive to 3% NaOCl, 0.1% CHX, and propolis ($5{\mu}l/ml$, $10{\mu}l/ml$) with zones of inhibition of 15, 14.5, 16, and 17 mm, respectively. The CFU of PBS, 3% NaOCl, 0.1% CHX, $5{\mu}l/ml$ and $10{\mu}l/ml$ of propolis led a 1, 7, 7, 5 and 7-log reduction. Among the groups tested, C. albicans was most sensitive to $10{\mu}l/ml$ of propolis, which showed the largest inhibition zones. Therefore, propolis can be a new antimicrobial therapy for oral mucosa disease in traditional medicine.

Purpose: Candida albicans can cause mucosal disease in many vulnerable patients. Also they are associated with denture-related stomatitis. Electrolyzed water is generated by electric current passed via water using various metal electrodes and has antimicrobial activity. The aim of this study was to investigate antifungal activity of electrolyzed water on C. albicans biofilm. Materials and Methods: C. albicans was cultured by sabouraud dextrose broth and F-12 nutrient medium in aerobic and 5% $CO_2$ condition to form blastoconidia (yeast) and hyphae type, respectively. For formation of C. albicans biofilm, C. albicans was cultivated on rough surface 6-well plate by using F-12 nutrient medium in $CO_2$ incubator for 48 hr. After electrolyzing tap water using various metal electrodes, the blastoconidia and hyphal type of C. albicans were treated with electrolyzed water. C. albicans formed blastoconidia and hyphae type when they were cultured by sabouraud dextrose broth and F-12 nutrient medium, respectively. Results: The electrolyzed water using palladium electrode (EWP) exhibited antifungal effect on blastoconidia of C. albicans. Also, the EWP significantly has antifungal activity against C. albicans biofilm and hyphae. In the electrolyzed water using various metal electrodes, only the EWP have antifungal activity. Conclusion: The EWP may use a gargle solution and a soaking solution for prevention of oral candidiasis and denture-related stomatitis due to antifungal activity.

Of the many pathogenic Candida species, Candida albicans is the main fungal pathogen of humans. The oral environmental factors considered in the Candida albicans colony forming unit test contain both host and microbial factors associated with candidiasis. In particular, Candida biofilms can develop on surfaces of prosthesis. The purpose of this study was to investigate the distribution of oral Candida species between the type of prosthesis and the situation of oral environment in patient with prosthetic appliance. The patients were 30 elderly subjects with different types of prosthesis, 7 who wore denture, 12 who wore implant and 15 who wore removable orthodontic appliance. We used Candida albicans colony forming unit test using saliva to exam the distribution of Candida albicans related with 5 oral environmental factors, gender, smoking or nonsmoking, alcohol/nonalcohol consumption, the type of prosthetic appliance and its treatment duration as well as tooth brushing frequency per day. In conclusion, for the patient's gender, site in the oral cavity and the type of prosthetic appliance and its treatment duration was associated with an increase in the distribution of Candida albicans in saliva. The distribution of Candida albicans within the oral cavity performs to be modulated to varying extents by oral environmental factors and, further investigations are required to elucidate these complex interactions.

Objectives: Candida albicans is an opportunistic pathogen that occurs as harmless commensals in the intestine, urogenital tract, and skin. It has been influenced by a variety of host conditions and has now evolved as a resistant strain. The aim of this study was thus detect the fluconazole resistant C. albicans from the root caries specimens and to computationally evaluate the interactions of an opaque-phase ABC transporter protein with the Psidium guajava bio-active compounds. Methods: 20 carious scrapings were collected from patients with root caries and processed for the isolation of C. albicans and was screened for fluconazole resistance. Genomic DNA was extracted and molecular characterization of Cdrp1 and Cdrp2 was done by PCR amplification. P. guajava methanolic extract was checked for the antifungal efficacy against the resistant strain of C. albicans. Further in-silico docking involves retrieval of ABC transporter protein and ligand optimization, molinspiration assessment on drug likeness, docking simulations and visualizations. Results: 65% of the samples showed the presence of C.albicans and 2 strains were fluconazole resistant. Crude methanolic extract of P. guajava was found to be promising against the fluconazole resistant strains of C. albicans. In-silico docking analysis showed that Myricetin was a promising candidate with a high docking score and other drug ligand interaction scores. Conclusion: The current study emphasizes that bioactive compounds from Psidium guajava to be a promising candidate for treating candidiasis in fluconazole resistant strains of C. albicans However, further in-vivo studies have to be implemented for the experimental validation of the same in improving the oral health and hygiene.
