Introduction:
The choice between diode laser and scalpel biopsies is crucial in clinical practice, impacting diagnostic accuracy, patient comfort, and post-procedural outcomes. This article reviews current literature to evaluate the effectiveness of these techniques, aiming to provide clarity on their respective advantages and limitations in biopsy procedures. Understanding these differences can aid clinicians in making informed decisions regarding biopsy methods, and optimizing patient care and procedural outcomes. Additionally, evaluating factors such as healing times, cost-effectiveness, and patient preferences can further guide the selection of the most appropriate biopsy technique. By integrating this knowledge, practitioners can enhance clinical decision-making and improve overall patient satisfaction.
Laser Versus Traditional Scalpel Biopsy: Which Is More Effective?
Exploring the benefits of diode lasers over the traditional scalpel method for obtaining biopsies, researchers found that diode lasers are highly patient-friendly, offering excellent hemorrhage control compared to incisions made manually with a surgeon's scalpel. Dental lasers are becoming increasingly popular, especially in oral medicine and surgery, due to their various advantages over traditional scalpel-based surgical methods.
The mode of oral biopsies is the most common procedure performed by the maxillofacial surgeon and is often inevitable because, for the diagnosis of a majority of conditions that require histopathological and differential diagnosis from serious lesions such as oral cancers and pre-cancers, biopsy can indeed be the gold standard procedure of choice for establishing a final diagnosis. However, dental patients may often be afraid to undergo the simple, non-invasive procedure of a biopsy due to anxiety or mental fears. It is important for dentists to convince and make patients aware of the importance of biopsy in critical scenarios, such as for establishing a differential diagnosis, especially in cases of severe and extensive oral lesions that definitely require a confirmative diagnosis.
Further, lasers can eliminate the need for the dentist or maxillofacial surgeon to suture tissues back in place. The pulsed mode, which can be used as the main application in diode lasers, has been proven to be more beneficial compared to the continuous mode. When the oral surgeon used the pulsed mode for biopsy through diode lasers, the amount of thermal damage was minimal, and postoperative pain was significantly reduced compared to the continuous mode of diode laser application.
What Are the Different Methods of Oral Biopsies?
Biopsy, whether performed surgically by the operator or with a laser, is usually intended to facilitate the prescription of a specific treatment modality necessary for establishing a final diagnosis. For instance, to determine the nature and prognosis of serious oral lesions, whether malignant or neoplastic, premalignant, or to differentiate non-neoplastic or benign tumors from actual cancerous lesions. A biopsy is a mandatory diagnostic procedure in modern dental and maxillofacial surgery.
A biopsy performed by a dental operator or surgeon can also serve as a document of medical-legal value, with the most common methods being scalpel, electrosurgical, and laser techniques. While the electrosurgical method has the advantage of cutting oral soft tissues with less trauma compared to the manually used scalpel method, the laser method can be more effectively utilized in future dentistry by dental operators, surgeons, and physicians.
Conventionally, lasers have been most commonly implemented in dentistry for root canal disinfection, tissue coagulation, and achieving effective blood control or hemostasis.
Current applications of lasers also include exposing covered implants or two-stage implants, root planing, gingival surgeries, periodontal surgical therapies, biopsies (that is, excising oral lesions), the surgical management of temporomandibular disorders, and commonly, modern-day preprosthetic surgeries.
What Are the Drawbacks of Diode Lasers?
Lasers for soft-tissue cutting, however, have their own drawbacks, such as the laser light posing a threat to the eye health of both the patient and the dental surgeon. This risk, however, can be completely mitigated by the mandatory use of protective glasses during the procedure.
Aside from this minor drawback, which can be overcome with protective eyewear, dental patients need not fear the pain associated with incisions made by a surgical scalpel. Compared to the conventional scalpel, the use of diode lasers offers several benefits, including effective tissue ablation, good blood clot formation (hemostasis), instant sterilization, reduced risk of bacterial infection or bacteremia, wound contraction, reduced edema at the surgical site, minimal scar tissue, and reduced mechanical trauma to the surgical site. It also eliminates the need for manual suturing of the surgical site, among other major advantages over conventional biopsy methods. Additionally, the use of air coolants and water suction can help nullify the slight thermal damage that may accompany laser biopsy.
Why Is Patient Acceptance Higher for Laser Biopsies?
Increased patient acceptance is further evident in dental research regarding biopsies performed with diode lasers, as patients experience minimal postoperative pain. Additionally, the use of diode lasers requires less anesthesia by dental operators compared to scalpel methods.
In terms of operating efficiency, researchers reveal that surgical scalpels and traditional biopsy methods have greater cutting efficiency than lasers. Furthermore, there is no need for protective equipment or eyewear, as is required with lasers. Additionally, traditional methods eliminate the risk of thermal damage to the biopsy site, which can occur even with the pulsed mode of diode lasers in some cases. The quality of histopathological slides is also higher with traditional scalpel methods because there is no trace of thermal damage to the tissues.
Conclusion:
To conclude, lasers represent a significant advancement in dental practice compared to traditional surgical methods. In the case of biopsy using diode lasers versus scalpels, despite minor drawbacks, lasers offer the potential for improved hemostasis, reduced postoperative trauma, and increased patient acceptance. A maxillofacial surgeon or dentist with better knowledge and application of diode lasers can utilize this technology to reduce patient chair time and prevent the discomfort associated with manual scalpel incisions. Additionally, lasers can streamline procedures, enhance precision, and offer a more comfortable experience for patients. Embracing this technology involves continuous training and adaptation to ensure optimal outcomes, improve procedural efficiency, and advance patient care standards. The future of dental surgery may well be shaped by the ongoing development and integration of laser technology.
