Malic Acid in Treatment of Xerostomia

Hams Hamed Abdelrahman52 enrolled

Overview

Background: xerostomia is a subjective sensation of dry mouth resulting from quantitative and /or qualitative changes of saliva. Patients receiving drugs like antihypertensives and antidepressants or patients receiving chemotherapy or radiotherapy for treatment of head and neck cancers may suffer from xerostomia. It also can be experienced in patients with systemic diseases like diabetes mellitus, systemic lupus erythematosus, sjogren's syndrome and rheumatoid arthritis. Malic acid spray with concentration of 1% has grabbed the attention over the last few years as an effective treatment for xerostomia. Study objective: To evaluate the effect of 1% malic acid spray in treatment of xerostomia in type 2 diabetic patients.

This randomized controlled clinical trial included 52 patients with type 2 diabetes mellitus suffering from xerostomia, divided equally into two groups. Group-I was managed by topical spray containing 1% malic. Group- II was managed by a placebo spray. Both groups received the treatment for 2 weeks. Dry mouth questionnaire scores (DMQ) and unstimulated salivary flow rate was collected before and after treatment.

Outcomes

Primary Outcomes

The unstimulated salivary flow rate

The unstimulated salivary flow rate will be obtained by the spit method every 30s for 15 minutes. Saliva will be collected in graduated tubes. Measurements will be expressed as milliliter per minute. Participants will be asked to refrain from eating, drinking and brushing their teeth at least 2 hours before saliva collection \- Hypo-salivation if the unstimulated salivary flow rate 0.1- 0.2 ml/min or less

Time frame: 4 weeks

Secondary Outcomes

scoring of severity of xerostomia

Each individual's responses will be scored and summed to give a single score and the higher scores represent more severe symptoms using Xerostomia Inventory-Dutch version
