Candida fungi is grouped in the fermenting fungi strain. Candida types are usually the normal flora and mostly get pathogens in immune system deficiency. The most common place of candidiasis infection is in the mouth. One of the effective factors of colonization intensity of this fungi is the mouth hygiene. The goal of this study is to determine the mouth fungi flora of dentistry students of Mazandaran University of medical science and to determine the correlation of this flora with the indexes of OHI-s, DMFT and saliva pH of this individuals. 119 individuals of dentistry students of Mazandaran participated in this analytic descriptive study. Clinical examinations for DMFT and OHI-s indexes were conducted. Saliva and plaque samples which were cultured in the saborodextrose and typedetermined in chromagar . After gathering data they were imported to SPSS22 and were analyzed. In total, 61 cases were albicans typed. DMFT index average was calculated to be 5.31±3.44, pH was 7.07±0.77 and OHI-s was 1.33±0.67. DT in individuals with colonization is meaningfully more than individuals who had colonization lower than 50 (P-value≤0.05). No meaningful differences between the growth number of lingual plaque and mouth saliva were observed. Among the sub-indexes of DMFT, DT had the lowest value. Considering OHI-s, students were placed in the medium level. The DMFT would be decreased down by increasing teeth brushing, mouth washing and flossing times. A meaningful correlation between gender and average of pH and OHI-s indexes was observed.
