Background Recurrent aphthous stomatitis (RAS), sometimes known as canker sores, is an infection of the oral mucous membranes caused by an inflammatory process. Triamcinolone and low-level laser therapy for recurrent aphthous ulcers were studied in this research, which evaluated their clinical efficacy. Methodology Among 60 subjects, 54 subjects fulfilled the inclusion criteria with an age range between 16 and 46 years. Subjects were randomly divided into two groups, the control group who received four times daily topical application of triamcinolone acetonide 0.1% and the test group who underwent a single application of low-level laser therapy on three alternate days. Evaluations were done on day 1, day 3, day 5, and day 10. Data obtained on oral-health-related quality of life (OHR-QoL) using the OHR-QoL questionnaire were used as baseline data. Clinical parameters like pain score were assessed using a visual analog scale, ulcer size using UNC-15 probe, and erythema and healing score were evaluated using erythema and healing scale. Result According to the OHR-QoL data, there was no statistically significant difference in the quality of life of test and control subjects. We found that pain and ulcer size reduced considerably (p=0.007) from the first day to the third day (p=0.000), and then dropped significantly again (p=0.000) on days 3-10 (p=0.000). On days 3 and 5, the test group showed significant reductions in pain and erythema (p=0.13), as well as an improvement in ulcer healing when compared to the control group. On days 3 and 5, the size of the ulcers decreased similarly in the control and test groups. On the 10th day, patients in both groups had less discomfort, erythema, and ulcer size, as well as improved healing of the ulcer. Conclusion Pain and erythema reduction and ulcer healing improvement were significantly higher in subjects in the test group as compared to those in the control group by day 3. The reduction in ulcer size was comparable to the control group on days 3 and 5, while the complete reduction in ulcer size was seen in both groups by day 10.
