Study summary

This study is designed to survey the therapeutic effect of a low molecular weight 5% nanochitosan paste against oral candidosis (denture stomatitis) and compare its efficacy with a standard Nystatin ointment.

Read the detailed description

Denture stomatitis, also called chronic atrophic candidosis, is a common chronic disease in people who use full dentures, primarily caused by Candida albicans. This randomized single-blind clinical trial evaluates the antifungal effect of nanochitosan particles prepared by the ionic gelation method in a 5% paste formulation. Thirty patients using full dentures and suffering from type 2 denture stomatitis are randomly divided into two groups of fifteen. One group receives the 5% nanochitosan paste and the other receives Nystatin ointment. Both groups apply their respective medications to the palatal areas four times a day for two weeks. Patients are instructed to remove their dentures during application. Clinical and microbiological assessments are performed before treatment and after two weeks to evaluate changes in erythematous plaque surface area, palatal cell culture colony counts, and burning sensation.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Change in erythematous surface area

    The size of the erythematous plaques under the denture-bearing surface is measured in square millimeters (mm2) to evaluate clinical healing.

    Time frame: Baseline, 1 week, and 2 weeks

Secondary outcomes

  1. Microbiological palatal cell culture findings

    The average number of fungal structures (mycelium and blastospore) observed in smears prepared from the palatal mucosa to quantify infection severity.

    Time frame: Baseline and 2 weeks

  2. Change in burning sensation

    Subjective burning sensation was assessed using a Visual Analog Scale (VAS). The scale is graded from a minimum value of 0 (no discomfort) to a maximum value of 10 (the highest rate of pain and irritation). Higher scores indicate a worse clinical outcome.

    Time frame: Baseline, 1 week, and 2 weeks
