Fungal Infection Rate and Composition Identification of Fungal Species Isolated From the Mouth of Dental Prostheses Patients in Nam Dinh Province, Viet Nam, In 2019-2020

Abstract

Objectives: Determination of fungal infection rate and composition identification of fungal species isolated from the mouth of a dental prosthesis patient in Nam Dinh province, Vietnam, in 2019-2020. Subjects and research methods: Cross-sectional descriptive studies with analysis were performed with 132 patients with dentures in Nam Dinh province in Vietnam, using random sampling. Results: 74 patients are male (accounting for 56.1%), 58 patients are women (accounting for 43.9%), there are 86 patients with oral thrush, accounting for 65.2%. 100% of patients with oral thrush infection are yeast type. Single-infected status is 43 patients, accounting for 50% and multi-infected status is 43 people, accounting for 50%. Identifying the composition of the fungus species, 11 species of fungi were identified, of which C. Albican species accounted for the highest proportion, with 43 patients (accounting for 29.25%), two less common fungi were: C. asahii with 01 disease people (accounting for 0.68%), C. Polymorpha with 01 patient (accounting for 0.68%). Conclusion: The percentage of patients with dentures infected with oral thrush is quite high (accounting for 65.2%), of which the main infection is C. Albican (accounting for 29.25%). Communication and education on oral health, oral hygiene, dental hygiene, and periodic examination should be strengthened in patients with dentures.
