<p>Relationship between oral hygiene and fungal growth in patients: users of an acrylic denture without signs of inflammatory process</p>

Abstract

Objectives To answer to the following questions: is there any relationship between oral hygiene and the growth of yeast in patients without mucosal inflammation; and is there a need for mycological examination patients without mucosal inflammation? Background Patients with candidiasis may report varied symptoms, but such infections are most often asymptomatic. In addition to its high incidence in denture users (60%–100%), there is a concern that Candida species from the oral cavity may colonize the upper gastrointestinal tract and lead to septicemia, which has a 40%–79% mortality rate and can require a prolonged hospital stay. It is thus important for all physicians to be aware of the risk factors, diagnosis, and treatment of oral candidiasis in older patients. Methods A retrospective study was carried out on a group of patients who had undergone mycological examination and assessment of the intensity of yeast growth, and oral hygiene. Results Ninety-one denture wearers who lacked signs of clinical inflammation were included in the study. The growth of Candida albicans was as follows: 14 patients had up to 20 colonies; 19 patients had over 20 colonies. Ten percent of patients with good oral hygiene proved to have more than 20 yeast colonies. 5% of patients with bad oral hygiene had more than 20 colonies. Conclusions There was no relationship found between hygiene and the growth rate of fungal microorganisms. In patients without clinical symptoms of stomatitis, mycological examination should be considered.

Quantification and Pathogenicity of Candida albicans in Denture-Wearing and Nondenture-Wearing Elderly

“…Interestingly, within the DW group, C. albicans shows a lower affinity for adherence to the tongue dorsa surfaces than to the mucosa-fitting surfaces of the dentures. This result and those of other studies 17,18 suggest that in elderly subjects, a nonshedding abiotic substratum is an ideal oral habitat for microbial attachment and growth.…”

Coexistence of Lack of Clinical Manifestation of Oral Mycosis and Systemic Diseases in Edentulous Patients Using Removable Prosthetic Restorations

“…Our study included the data of patients who used removable prosthetic dentures in the upper arch for a minimum of 5 years [ 16 ]. The exclusion criteria were smoking, postoperative denture, framework, the lack of a date in the electronic database [ 16 , 17 , 18 ] and the concomitant presence of two or more diseases. Information on the occurrence of systemic diseases (hypertension, cardiovascular diseases, diabetes, asthma, ulcers, and icterus) was obtained from patients during their medical history [ 16 , 18 ].…”

“…Patients were not to perform any hygienic procedures, nor were they to eat breakfast. Examination was done by a specialist in prosthetic dentistry [ 16 , 18 ]. Immediately after the removal from the mouth of the patient of the upper denture, the doctor swabbed the palate between 2 and 3 palatal folds.…”

“…After mycological examination, antifungal susceptibility was determined for the patients using a fungi test (Bio-Rad, Marnes-la-Coquette, France) and using the disk-diffusion method with Nystatin 100 units (Emapol, Gdańsk, Poland) [ 16 , 18 ].…”

“… The health status of patients who did not show signs of inflammation, but who qualified for treatment, was compared with that of patients with clinically apparent inflammatory symptoms, and who also became eligible for antifungal pharmacotherapy after receiving the results. The health status of the Newton group 0 patients who qualified for pharmacological treatment due to number of fungal colonies was compared with that of the patients in whom symptoms of inflammation of mucosa were visible (regardless of whether they qualified for treatment or not) [ 16 , 18 ]. …”
