Resumo: | The occlusal splint constitutes a resource frequently used on temporomandibular dysfunction (TMD) and orofacial pain treatment, including the denture-wearing patients. Considering the active participation of lips in the functions of the stomatognathic system, the aim of this study was to verify the influence of occlusal splints on electromyography activity (EMG) of two portions – upper (OBU) and lower (OBL) of orbicularis oris muscle, during the yogurt suction. EMG was accomplished before and 70 days after the use of these splints, in 8 edentulous denture-wearing patients and that had signs and symptoms of TMD. The myoeletric signs were recorded by a electromyography (*Lynx Eletronics) with Butterworthtype band pass filter (20-500 Hz) with gain of 100 times and A/D converter board. The signs were caught by Ag/AgCl surface electrodes (Medi Trace) and displayed through by Aqdados Software installed in an Ibm-pc 486 DX2. The EMG sign was processed by Matlab® Software and the averages of the non-normalized amplitude envoltories (NNA) were statistically analyzed using Mann-Whitney test (p < 0,05). The NNA values found on pre-treatment was 60,11 ± 4.28 and 86,15 ± 6.15 μV and in the post-treatment was 106,0 ± 4.80 and 103,71 ± 3.83 μV for the portions OBU and OBL respectively. The verified statistical difference was highly significant (p < 0,0001) when compared the same muscular portion before and after use of splints. The results of this study, on those experimental conditions used, may conclude that the use of occlusal splints promoted a significant increase of the electric activity of the orbicularis oris. UNITERMS: occlusal splint; orofacial pain; electromyography. |

Considerando a participação ativa dos lábios nas funções do sistema estomatognático, o objetivo deste estudo foi verificar a influência das placas oclusais na atividade eletromiográfica (EMG) das duas porções – superior (OBS) e inferior (OBI) do músculo orbicular da boca, durante sucção de iogurte. A EMG foi realizada antes e 70 dias após o uso destes aparelhos, em 8 pacientes edêntulos, portadores de prótese total e que apresentavam sinais e sintomas de DTM. O sinal mioelétrico foi coletado por um eletromiógrafo (*Lynx Eletronics), com filtro tipo Butterworth (20-500 Hz) com ganho de 100 vezes e placa conversora A/D. Os sinais foram captados por eletrodos de superfície de Ag/AgCl (Medi Trace) e registrados por meio do software Aqdados instalado em um computador Ibm-pc 486 DX2. O sinal EMG foi processado pelo software Matlab® e as médias das amplitudes não normalizadas (ANN) foram testadas estatisticamente pelo teste Mann-Whitney (p < 0,05). Os valores encontrados das ANN no prétratamento foram de 60,11 ± 4.28 e 86,15 ± 6.15 μV e no pós-tratamento de 106,0 ± 4.80 e 103,71 ± 3.83 μV para as porções OBS e OBI, respectivamente. A diferença estatística verificada foi altamente significativa (p < 0,0001) quando comparada à mesma porção muscular antes e após o uso das placas. Os resultados deste estudo, nas condições experimentais utilizadas, permitem concluir que o uso das placas oclusais promoveu um aumento significativo da atividade elétrica do orbicular da boca.
