ABSTRACT

The use of high-power lasers has facilitated and improved human papillomavirus (HPV) treatment protocols and has also become very popular in recent years. This application has been more frequently used in hospitals, especially in gynecology. The present study aimed to evaluate the effects of high-power diode laser to remove oral lesions caused by HPV and the consequent effects on virus load following the wound tissue healing process compared with one of the most conventional surgical techniques involving electrocautery. Surgeries were performed on 5 patients who had 2 distinct lesions caused by HPV. All patients were submitted to both electrocautery and high-power diode laser. Following a 20-day period, when the area was healed, sample material was collected through curettage for virus load quantitative analysis.Observation verified the presence of virus in all the samples; however, surgeries performed with the laser also revealed a significant reduction in virus load per cell compared with those performed with electrocautery. The ease when handling the diode laser, because of the flexibility of its fibers and precision of its energy delivery system, provides high-accuracy surgery, which facilitates the treatment of large and/or multifocal lesions. The use of high-power diode laser is more effective in treatment protocols of lesions caused by HPV.

ABSTRACT

Os autores apresentam um caso clínico de Epidermólise Bolhosa (EB), atendido na clínica da disciplinade Odontologia para Pacientes Especiais do curso de Odontologia da Universidade Cruzeiro do Sul(Unicsul-São Paulo), com lesões na cavidade oral, tratadas com laser de baixa intensidade. Há poucoscasos relatados na literatura de lesões de EB na cavidade oral, e a forma de manejo desses pacientespelo cirurgião-dentista. O artigo discute também aspectos relacionados à sua definição, ao diagnóstico,à etiologia e ao tratamento dessa alteração, indicando a laserterapia como alternativa no tratamentosintomático das EB.


The authors present a case of epidermolysis bullosa (EB), attended the clinic of the discipline ofdentistry for special patients the course of Dentistry, University Cruzeiro do Sul (Unicsul-Sao Paulo),with lesions in the oral cavity treated with low-level laser intensity. There are few cases reported in theliterature of EB lesions in the oral cavity, and how to manage these patients by dentists. The article alsodiscusses issues related to its definition, diagnosis, etiology and treatment of this amendment, indicatingthe laser therapy as an alternative in the symptomatic treatment of EB.
