Abstract
The 450 nm wavelength blue diode laser is one of the newest technologies used in soft tissue oral surgeries, which provides significant results even with minimal power. This method allows for precise surgery, without pain or bleeding, without the need for stitches, rapid recovery, and greater patient satisfaction. This article introduces the clinical application of this laser in the removal of a lower lip fibroma and examines its benefits, results, and therapeutic values.

Keywords: blue laser, diode, oral surgeries, patient satisfaction, oral soft tissue

Introduction

Since the introduction of lasers in dentistry in the 1960s, this technology has brought about major changes in the field of oral and dental treatments. Laser surgery not only reduces operating time and bleeding control, but also provides better visibility for the surgeon and a more comfortable experience for the patient due to its high precision.

Various lasers are used in oral surgeries, but blue light (450 nm) has attracted much attention due to its unique properties. In addition to its antibacterial properties and helping to repair tissues, this light has also been used in cases such as tooth whitening and polymerization of dental resins. However, its application in oral soft tissue surgery is a new and developing topic.

Materials and Methods

A 38-year-old female patient presented with a lesion on the edge of the lower lip. The lesion, which had developed over a year, had grown more in recent months. The clinical diagnosis was fibroma (benign lesion). To avoid bleeding and scarring caused by traditional surgery, lesion removal with a 450 nm diode laser was chosen.

Features of this procedure:

No need for anesthetic injection (local anesthesia only)

No sutures

Operation time less than two minutes
Complete control of bleeding and tissue temperature
Follow-up of the patient at one and three months after the procedure showed that no complications occurred and the lesion did not return.

Results

The patient did not feel any pain during the procedure.
After the lesion was removed, there was no bleeding and no sutures were required.
The surgical site healed completely within a week.
The patient did not take any medications such as antibiotics or painkillers during the recovery period.
No infection, swelling, or discomfort was reported.
Histopathological examination of the specimen showed fibrous connective tissue with a neat cut and minimal carbonization.
Key advantage: This laser allows for precise removal of the lesion with minimal tissue damage, and the quality of the specimen for pathological examination is fully preserved.
