RESUMO

Introduction: Orofacial paresthesia is due to trauma to the neural structure of a particular nerve. In dentistry alterations caused by nerve damage in most cases are presented with transient symptomatology. However, it has been agreed by several authors that persistent inferior alveolar sensory aberrations for more than 6 months leave some degree of disability or are considered permanent. The objective of the present study is to report the clinical case of a young patient submitted to low-level laser therapy for the treatment of paresthesia of the inferior alveolar nerve after removal of a complex odontoma in the posterior region of the mandible. Methods: Twenty-four hours after the surgical procedure the patient started the low-level laser therapy with the following parameters: 100 mW of potency, 140 J/cm2 of energy density, 4 J of energy per application point, 40 seconds of application per point and 0.028 cm2 of spot area. For this particular case, the technique of alternation of laser wavelengths was used, in the first session of which visible red of 660 nm was applied, followed by near-infrared of 808 nm and so on. Results: In the first session, the score on the visual analog scale (VAS) was "3". In the tenth and last sessions, the patient reported a VAS "9". Conclusions: It seems that the early initiation of the low-level laser therapy favors a better outcome in cases like the one presented in this paper. The technique of alternation of laser wavelengths between sessions seems to have some role in the outcome possibly because of the constant stimulation of different chromophores along the treatment course. These two factors need further confirmation and validation through randomized clinical trials.

RESUMO

Frontal bone fracture treatment is still an issue of research in craniofacial surgery and neurosurgery. The aims of the treatment are to reduce the complication risks and to keep the aesthetic of the face. Before the management of this fracture type, it is necessary to consider the permanence or not of the frontal sinus function. Rapid prototyping has been an aid tool on planning and simulation of the surgical procedure, improving the diagnostic quality and the implant manufacture, beyond reducing the operative time. Among the used materials on treatment of these fractures, titanium mesh shows large versatility and ease of handling. Poly(methyl methacrylate) has been used in defects of partial thickness or irregularities on cranial surface. The aim of this study is to report a case of a patient presenting sequelae of large fracture of anterior wall of frontal bone, treated by a titanium mesh associated with the customized poly(methyl methacrylate) implant from the rapid prototyping. It could be concluded that the use of this technique showed itself effective on patient treatment, and rapid prototyping demonstrated being a valuable tool showing predictable and satisfactory results.
