ABSTRACT
Assess whether the Lucia Jig is a device that promotes masticatory muscle relaxation in individuals with temporomandibular dysfunction. This study was carried out in three stages (interviews, clinical examination, and laboratory) and participation of adult individuals, between 21 and 40 years of age, of both genders, who replied to the RDC/TMD questionnaire to diagnose muscular temporomandibular dysfunction. The Lucia Jig was prepared and electromyographic examination of the masseter and temporal muscles was performed bilaterally, in the postural condition of the mandibular at rest, after immediately installing the Lucia Jig in the oral cavity and at periods of 5, 10, 15, 20, and 30 min. The values obtained were compared using repeated measures (p < 0.05) over the entire duration of the experiment (0 to 30 min) with the Lucia Jig. There was an increase in the normalized electromyographic signal of the masticatory muscles, with the use of the Lucia Jig over the period of 30 min, with no statistically significant difference. Based on the results of this study through electromyographic data, the device did not promote masticatory muscle relaxation in individuals with muscular temporomandibular dysfunction.
Avaliar se o Jig de Lucia é um dispositivo que promove relaxamento dos músculos mastigatórios em indivíduos com disfunção temporomandibular. O estudo foi realizado em três etapas (entrevista, exame clínico e laboratorial) com a participação de indivíduos adultos, entre 21 e 40 anos de idade, ambos os gêneros, que responderam ao questionário RDC/TMD para diagnosticar disfunção temporomandibular muscular. O Jig de Lucia foi confeccionado e o exame eletromiográfico foi realizado nos músculos masseter e temporal, bilateralmente, na condição postural da mandíbula em repouso e imediatamente depois da instalação do Jig de Lucia na cavidade oral nos períodos de 5, 10, 15, 20 e 30 min. Os valores obtidos foram comparados ao longo de toda a duração do experimento (0 a 30 min) com o Jig de Lucia, utilizando o teste de medidas repetidas (p <0,05). Houve aumento no sinal EMG normalizado dos músculos da mastigação, com o uso do Jig de Lucia ao longo do período de 30 min, sem diferença estatística significante. Com base nos resultados deste estudo, conclui-se que o dispositivo Jig de Lucia, por meio dos dados eletromiográficos, não promove relaxamento dos músculos mastigatórios em indivíduos com disfunção temporomandibular muscular.

Introduction : Lip squamous cell carcinoma is a malignant lesion of aggressive behavior, which must be recognized by health professionals to prevent damage to patient's health.Objective:To present incisional biopsy importance as an effective clinical approach for the diagnosis of lip squamous cell carcinoma and actinic cheilitis malignancy as well as the professional's lack of knowledge on these two diseases. Case report:The patient was under medical treatment due to be positive for human immunodeficiency virus and because of the actinic cheilitis on lower lip. Because the patient did not observe the labial lesion regression, he searched for the School of Dentistry of the University Center of the Educational Foundation of Barretos, where he underwent biopsy. This procedure confirmed the diagnosis of lip squamous cell carcinoma. The patient was referred for treatment in a specialized cancer center and has been living with the cancer consequences. Conclusion:The physician and dentist must be aware of the main clinical features of lip squamous cell carcinoma so that they can establish its correct diagnosis and early treatment.
