Evaluation of Zinc Oxide Ointment in Treatment of Recurrent Aphthous Stomatitis
This randomized placebo-controlled trial evaluated the effectiveness of zinc oxide ointment in the treatment of recurrent aphthous stomatitis (RAS).
The study included 100 patients randomly assigned to receive either zinc oxide ointment or a placebo, applied three times daily for six days.
Pain intensity was measured using a visual analogue scale (VAS), and oral health-related quality of life was assessed using OHIP-14 at baseline and on days 1, 3, and 6.

Detaljerad beskrivning
This randomized, placebo-controlled clinical trial investigated the efficacy of topical zinc oxide ointment in the management of recurrent aphthous stomatitis (RAS). A total of 100 participants diagnosed with RAS were enrolled and randomly assigned in equal proportions to either the intervention group receiving zinc oxide ointment or the control group receiving a placebo formulation. The study medication was applied topically three times daily for a duration of six consecutive days.
Clinical outcomes were assessed at baseline and on days 1, 3, and 6 post-treatment initiation. Pain intensity was evaluated using a visual analogue scale (VAS), while oral health-related quality of life was measured using the Oral Health Impact Profile (OHIP-14). Additional clinical observation included assessment of ulcer size and surrounding erythematous halo.

- Ulcers are of a duration of less than 48 hours.
Exclusion Criteria:
- -Participants with removable prosthetic or orthodontic appliances (to avoid potential effects on healing).
- Tobacco chewers, smokers or alcoholics.

Visual analog scale
Tidsram: Before treatment ,Day 1,Day 3 and Day 6
|
A Visual Analog Scale (VAS) is a subjective, validated, 100mm (or 10cm) straight-line tool used in healthcare to measure pain intensity, fatigue, or other sensations.
Patients mark their sensation level between "no pain" (0) and "worst pain imaginable" (100).
It is highly sensitive for tracking changes in symptoms over time

IPD-planbeskrivning
This study investigated whether zinc oxide (ZnO) ointment can help reduce pain and improve healing in patients with recurrent aphthous ulcers (mouth ulcers).
One hundred participants were divided into two groups: one received ZnO ointment and the other received a placebo.
The treatment was applied three times daily for six days.
Pain levels and oral health impact were measured before and after treatment.
The results showed that ZnO ointment helped reduce pain faster in the early days compared to placebo, but there was no significant difference in overall quality of life after six days.
