Which method is recommended when treating an aphthous ulcer?

The recommended method for treating an aphthous ulcer is the noncontact mode with an infrared diode laser. This approach is effective because it allows for the delivery of laser energy without directly touching the ulcerated area. The infrared diode laser can penetrate the tissues at a specific depth, promoting healing while minimizing discomfort for the patient.

Using the noncontact method helps to avoid any additional irritation that could occur from direct contact with the ulcer, which can be sensitive and painful. Additionally, this technique promotes the stimulation of healing processes, such as increased blood flow and cellular regeneration, while also decreasing inflammation and pain associated with the ulcer.

In contrast, methods like direct contact mode may cause irritation to the ulcer, while a topical anesthetic might temporarily numb pain but does not address the underlying inflammation and healing processes needed for recovery. High-frequency pulsing generally pertains to different therapeutic approaches and lacks the specific benefits offered by the infrared diode laser in this context.
