Adjunct Use of Low-Level Laser Therapy on the Treatment of Necrotizing Ulcerative Gingivitis: A Case Report

Abstract

Necrotizing ulcerative gingivitis (NUG) is a microbial disease of the gingiva in the context of an impaired host response. This form of gingivitis is relatively rare. NUG is an infection characterized by gingival necrosis presenting as "punched-out" papillae, spontaneous bleeding, pain, oral malodor, and pseudomembrane formation. The primary predisposing factors are bacterial plaque and an inadequate diet, but smoking and psychological stress may also affect the disease severity. NUG is associated with a characteristic bacterial flora, which includes fusiform bacteria, spirochetes, and Prevotella intermedia. Conventional treatment includes control of both the bacterial plaque and the secondary factors, as well as topical or systemic treatment biostimulative effect on wound healing, pain control, and inflammatory processes. Patients with NUG were treated using adjunct use of a diode laser (980 nm) for the control of pain and to accelerate the wound healing at day 2. 3. 5. 9, energy density was 9 J/cm 2 . After treatment, the patients' quality of life improved faster than with conventional treatment. These results suggest that low-level laser therapy (LLLT) is an effective treatment for the reduction of pain levels and healing times. As a result, our case report shows that LLTT has a positive effect in relieving the symptoms of NUG.

Gingival augmentation by combination of laser and Acellular Dermal Matrix allograft in a patient with dystrophic form of epidermolysis bullosa: A case report

“…In addition, a diode laser was used to provide biostimulation to the area. Biostimulation provides a photochemical effect through which light is absorbed to cause chemical changes in cells . Diode lasers have been reported to stimulate cell proliferation via stimulation of mitochondrial respiration and ATP pathway, shift in overall cell redox potential in the direction of greater oxidation, and also changes in expression of several proteins related to epithelial proliferation and maturation in in vitro studies.…”

Blue and red light photoemitters as approach to inhibit Staphylococcus aureus and Pseudomonas aeruginosa growth

“…Light at 600-660 nm wavelength are commonly used as method in tissue regeneration, reduction of local inflammation and even as superficial analgesic therapy (Hadis et al, 2016;Özberk et al, 2018). However, the use of red light for bacterial infection is subject of exhausting debate since data in the literature are still controversial (Marciano et al, 2012;Kim et al, 2013;Barboza et al, 2015;Gomes et al, 2018).…”

Gengivite Ulcerativa Necrosante: um relato de caso

“…Nas regiões de gengiva interdental dos elementos anteroinferiores (principalmente entre os elementos 42 e 43) e na região dos dentes 35 e 36 e distais de 47 e 37 foram observadas regiões de necrose (Figura 1), inversão da papila Inter dentária com ulcerações, exsudato purulento e sangramento ao toque, de forma semelhante à casos observados na literatura relacionados à GUN. 27,29,30 Além disso, ocorreu intensa sintomatologia dolorosa ao toque e odor fétido característico. Pequena quantidade de placa visível foi observada em comparação com a elevada destruição tecidual.…”

“…Neste contexto, a suspeita diagnóstica foi de GUN. 1,17,27,29,30 Desta forma, uma profunda investigação dos fatores predisponentes foi realizada. Direcionando o diálogo, o paciente reportou estar em semana de provas na universidade, estando mais estressado que o habitual.…”

“…4,9 Neste contexto, o manejo ampliado e holístico dos indivíduos que apresentam GUN deve ser realizado considerando todos fatores que podem ser coadjuvantes às manifestações orais da doença, como por exemplo o estresse. No entanto, a maioria dos relatos de casos não apresentam esta abordagem ampliada, detendo-se basicamente às manifestações clínicas e ao manejo da doença 27,28 ou relacionando a GUN com infecção por HIV. 29,30 Assim, este relato de caso descreve a abordagem diagnóstica e o manejo terapêutico conservador e ampliado de um caso clínico de GUN em um paciente masculino, de 21 anos, melanoderma, sem doença sistêmica e com o estresse como provável mecanismo de patogênese predisponente envolvido.…”
