Orthodontic treatment makes necessary to use a longtime fixed-band appliance, it offers suitable conditions for fungal growth, dentures also allow fungal contamination on their surfaces. The aim of our study is the identification of the fungal species colonizing surfaces of dental appliances, the crosssectional study was carried out on 60 patients wearing dental appliances, during 5 months, and sterile swabs were used and inoculated into Sabouraud's dextrose agar tubes. Yeast identification has been based on germ tube test, chlamydoconidia production and biochimical tests (Auxacolor, Api 20 C). The overall prevalence of fungal contamination of dental orthodontic appliance was 35%. The prevalence rate was 40% among patients who had dental appliances for 1 to 2 months, and 45,5% fort patients brushing their teeth at least twice daily, but no statistical relation with mycosis was found. Pain, burning and discomfort were correlated to fungal carriage p=0,038; OR=4,867 IC 95% (1.09-21.74). The fungal species most recovered were Candida parapsilosis 21.47%, Candida Zeylanoides 21.47%, Candida albicans 17.38%, and Cryptococcus terreus 13.04%. Mycological monitoring of dental prosthesis is crucial to prevent possible fungal's adverse health effects.

“…In 2008, contamination of the waterlines with Pseudomonas was reported in 20 dental clinics in São Paulo, and 28 out of 40 samples of water syringes had HPC measurements between 200 and 2000 CFU/mL [24]. More recently, in 2017, another study from Brazil reported fungal contamination of DUWLs [25]. The presence of mycobacteria was not assessed in these studies from Brazil.…”

“…Very few studies in Latin America have assessed water quality in dental offices. In fact, after searching the PubMed database, we found only three publications in the English language, all from Brazil [23][24][25]. In a 2003 study, 14 of the 15 dental units from private dental clinics in São Paolo had HPC measurements of approximately 50,000 to 300,000,000 microorganisms per milliliter [23].…”

Three cases of severe odontogenic infections due to nontuberculous mycobacteria (NTM) in Venezuela that were directly associated with dental procedures and the finding of dental unit waterlines (DUWLs) in dental offices that were colonized with mycobacteria species was the reason for assessing the water quality of DUWLs in dental offices in two capital cities in South America, namely, Quito and Caracas. The main water supplies and the water from 143 DUWLs in both cities were sampled and especially checked for contamination with NTM. To measure the overall bacteriological quality of the water also the presence of heterotrophic bacteria, coliform bacteria, and Pseudomonas was determined. Results showed that respectively 3% and 56% of the DUWLs in Quito and Caracas yielded NTM species (up to 1000 colony-forming units (CFU)/mL). Furthermore, high and unacceptable total viable counts of heterotrophic bacteria and/or coliform bacteria and Pseudomonas were detected in 73% of the samples. We conclude that, in both cities, the water in the majority of DUWLs was contaminated with NTM and other potential pathogens, presenting a risk to human health. The detection of NTM in DUWL water with acceptable heterotrophic bacteria counts shows the need to include NTM in water quality testing. Mycobacteria are more resistant to disinfection procedures than other types of vegetative bacteria, and most testing protocols for DUWLs do not assess mycobacteria and thus do not guarantee risk-free water.

Candida albicans is one of the pathogenic fungal species which causes oral infections. One of the methods to minimize the risk of fungal infection is by application of asepsis procedure through gargling with antiseptics. Ozone has high oxidative properties, therefore, it is considered as an antiseptic agent. Plasma Study Center of Diponegoro University has developed an ozone generator machine which opens up an opportunity to identify ozone properties as an antiseptic in controlling the number of fungal colonies, especially Candida albicans. This study was aimed to identify the effects of ozone exposure on the number of fungal colonies of Candida albicans. This was a laboratory experimental study with one-group pretest-posttest design. A total of 32 samples of Candida albicans suspensions were divided into two groups (16 each). Group 1 was not treated with ozonation, while group 2 were ozonated. Then, the two groups were cultured in SDA media using the spread plate method and were incubated for 48 hours. The data were obtained by calculating the number of fungal colonies growing in SDA media. The Wilcoxon test obtained a p-value <0.05, meaning that there were differences in the colony number of Candida albicans before and after ozonation. In conclusion, ozone exposure has a significant effect on the number of fungal colonies of Candida albicans. Further studies are needed adding variables or parameters.

Salah satu metode untuk meminimalkan risiko infeksi jamur ialah melalui penerapan prosedur asepsis dengan berkumur menggunakan antiseptik. Ozon memiliki kemampuan oksidasi tinggi sehingga dipertimbangkan untuk menjadi bahan antiseptik. Pusat Penelitian Plasma Universitas Diponegoro telah mengembangkan mesin generator ozon yang membuka peluang untuk mengetahui kemampuan ozon sebagai antiseptik dalam mengendalikan jumlah koloni jamur terutama Candida albicans. Penelitian ini bertujuan untuk mengetahui adanya pengaruh paparan gas ozon terhadap jumlah koloni jamur (Candida albicans). Jenis penelitian ialah eksperimental laboratorik dengan one group pretest-posttest design. Sebanyak 32 sampel suspensi jamur Candida albicans dibagi menjadi dua kelompok (masing-masing 16 sampel). Kelompok 1 tidak dilakukan ozonasi dan kelompok 2 dilakukan ozonasi kemudian kedua kelompok dikultur dalam media SDA dengan metode spread plate dan diinkubasi 48 jam. Data diperoleh dengan menghitung jumlah koloni jamur yang tumbuh pada media SDA. Hasil uji statistik Wilcoxon mendapatkan nilai p<0,05 yang berarti terdapat perbedaan jumlah koloni jamur (Candida albicans) sebelum dan setelah pemberian gas ozon. Simpuolan penelitian ini ialah paparan gas ozon berpengaruh secara bermakna terhadap jumlah koloni jamur (Candida albicans). Penelitian lanjutan diperlukan dengan penambahan variabel atau parameter.Kata kunci: gas ozon; koloni jamur; Candida albicans
