  • The Treatment of Herpes Labialis with a Diode Laser (970 Nm) — a Field Study
    I clinical article The treatment of herpes labialis with a diode laser (970 nm)—a field study DrSimoneSuppelt AbstrAct Herpes labialis is an infection caused by the herpes simplex virus HSV 1 and, less frequently, HSV 2. In dental prac - tices the diode laser is mainly used in periodontology, endodontics and minimally invasive surgery. Many of those affected by herpes are unaware that laser treatment can successfully alleviate their symptoms. In this field study, 11 patients who suffer from acute herpes were treated with a 970 nm diode laser. The areas which the patients described as being affected by herpes were irradiated at a distance of 1 –3 mm (2.0 W, 10 Hz, 50 % duty cycle, 320 µm optical fiber). Several patients felt the symptoms subside during the treatment. For the majority of patients, the symptoms did not occur again after treatment. All of the patients were satisfied with the treatment. Laser treatment of herpes labialis using a 970 nm diode laser is an effective way for me to help my patients both quickly and simply. Keywords Diode laser, 970 nm, herpes labialis, HSV Introduction An outbreak of herpes labialis can be accompanied by var - ious symptoms. As a rule, in the early stages such symptoms With a wavelength of 970 nm and a maximum output of include dry lips and a tingling/itching sensation.

It can both stimulate and sup- press biological effects. The property of PBM contributes to the analgesic, anti-inflammatory, and wound healing effects. Photobiomo- dulation therapy (PBMT) has a wide variety of clinical applications that include wound healing, prevention of cellular death, promotion of repair mechanisms, reduction of inflammation, pain relief, etc. Hence, it is being used effectively in the field of oral medicine and has shown promising results in the management of oral mucosal lesions, orofacial pain, and other orofacial ailments without much signifi- cant adverse effects. The purpose of this review is to discuss the applications of PBMT in the field of oral medicine.

This section ol Quintessence International is cnmrnitted to presenting evidenced-based olinical practice guidelines in collaboration with oral and nonoral health care providers. Clinical Practice Guidelines Herpes simplex type-1 virus infection Michaeli A. Huber, Oral infection caused by the herpes simplex virus represents one ot the more oommon conditions the den- tal practitioner will be oalied upon to manage. Unique in its ability to eslablish iatency and undergo subse- quent recurrence, it is an ubiquitous intectious agent for which a cure does not exist. For the immunocom- petent patient, herpes virus simplex infection typicaiiy represents nothing more than a nuisance. However, for the immunooompromised patient, this infection is associated with increased morbidity and mortality. Recentiy introduced antiviral drug regimens may reduce the morbidity and potential mortality of the herpes simplex virus, especiaiiy in immunocompromised patients. The value of antivirai therapy in the manage- ment of recurrent herpes simplex virus infection in the immunocompetent patient remains an area of con- tentious debate.

  • Recurrent Herpes Simplex Labialis: Selected Therapeutic Options
    C LINICAL P RACTICE Recurrent Herpes Simplex Labialis: Selected Therapeutic Options • G. Wayne Raborn, DDS, MS • • Michael G. A. Grace, PhD • Abstract Recurrent infection with herpes simplex virus 1 (HSV1), called herpes simplex labialis (HSL), is a global problem for patients with normal immune systems. An effective management program is needed for those with frequent HSL recurrences, particularly if associated morbidity and life-threatening factors are present and the patient’s immune status is altered. Over the past 20 years, a variety of antiviral compounds (acyclovir, penciclovir, famciclovir, vala- cyclovir) have been introduced that may reduce healing time, lesion size and associated pain. Classical lesions are preceded by a prodrome, but others appear without warning, which makes them more difficult to treat. Various methods of application (intravenous, oral, topical) are used, depending on whether the patient is experiencing recurrent HSL infection or erythema multiforme or is scheduled to undergo a dental procedure, a surgical proce- dure or a dermatological face peel (the latter being known triggers for recurrence). This article outlines preferred treatment (including drugs and their modes of application) for adults and children in each situation, which should assist practitioners wishing to use antiviral therapy.
