What this trial studies

This clinical trial aims to evaluate the effectiveness of Hibiscus Sabdariffa L. mouth rinse in alleviating xerostomia, particularly in patients who have undergone radiotherapy for head and neck cancer. The primary objective is to measure subjective dry mouth scores, while secondary objectives include assessing changes in salivary flow rates and objective dry mouth scores. The study will involve patients who report dry mouth symptoms and will exclude those with certain health conditions or sensitivities. The trial is conducted at Ahmed Maher Teaching Hospital in Cairo.

Who should consider this trial

Good fit: Ideal candidates are adults over 20 years old who experience xerostomia with specific dry mouth scores.

Not a fit: Patients with serious illnesses, autoimmune diseases, or those who are pregnant or vulnerable may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients suffering from radiation-induced dry mouth.

How similar studies have performed: While there have been studies on various treatments for xerostomia, the specific use of Hibiscus Sabdariffa for this condition is relatively novel.
