RESUMO Objetivo Verificar o efeito da bandagem elástica no músculo trapézio, por meio da eletromiografia e de um questionário autorreferido em adultos saudáveis. Método Participaram 51 adultos saudáveis, de ambos os sexos, na faixa etária entre 20 e 35 anos. Os sujeitos foram divididos em três grupos: G1, que utilizou a bandagem elástica com tensão; G2, que utilizou a bandagem elástica sem tensão; e G3, grupo controle, que não utilizou a bandagem. A aplicação da bandagem ocorreu no músculo trapézio, bilateralmente. Para a mensuração dos resultados, foram coletados sinais eletromiográficos antes, durante e depois do uso da bandagem, e foi aplicado um questionário qualitativo. Resultados Não houve diferenças significativas nos achados eletromiográficos antes e depois do uso da bandagem, em cada grupo e na comparação entre os grupos. Na confrontação G1 com G2, nos momentos antes e durante o uso da bandagem, foi verificada uma diferença estatisticamente significante na variável contração voluntária máxima do lado esquerdo. No questionário, a maioria dos sujeitos relatou sensação de relaxamento com o uso da bandagem. Conclusão Os sujeitos da amostra que utilizaram a bandagem não apresentaram diferenças estatisticamente significantes na eletromiografia. Em relação ao questionário, a maioria dos sujeitos pesquisados afirmou sensação de relaxamento após o uso da bandagem.

ABSTRACT Purpose To verify the elastic therapeutic tape effects on the trapezius muscle in healthy adults, using data from surface electromyography and a self-reported questionnaire. Methods A total of 51 across sex healthy adults were enrolled in this study, whose age range was 20 to 35 years.. The individuals were divided into three groups: G1, who wore the elastic therapeutic tape applied with tension; G2, who wore the elastic therapeutic tape applied with no tension; and G3, control group, who did not wear the elastic therapeutic tape. The elastic therapeutic tape was bilaterally applied on the trapezius muscle. For measuring results, surface electromyography signals were collected before, while and after the elastic therapeutic tape was worn, and a qualitative questionnaire was applied. Results There were no significant differences in either pre- or post-electromyography findings within each group, or when groups were compared. When comparing G1 and G2 moments before and while the elastic therapeutic tape was worn, a statistically significant difference was noted during the maximum voluntary contraction variable on the individuals’ left side. When answering the questionnaire, most individuals mentioned a relaxing feeling while wearing the elastic therapeutic tape. Conclusion The individuals wearing the elastic therapeutic tape in this sample did not present any significant differences during the surface electromyography assessment. As for the questionnaire, most of the individuals investigated reported a relaxing feeling after wearing the elastic therapeutic tape.

RESUMO Objetivo: caracterizar e comparar as alterações de fala relacionadas às alterações do frênulo lingual em escolares, dos 8;6 anos aos 10;11 anos entre grupo controle e pesquisa. Métodos: avaliou-se 52 crianças em idade escolar (8;6 anos a 10;11 anos), de ambos os gêneros, regularmente matriculadas em Instituto privado, divididas em: grupo controle (sem alteração do frênulo lingual) e grupo pesquisa (com alteração do frênulo lingual). As crianças foram avaliadas por meio do Protocolo de Avaliação em Motricidade Orofacial utilizado em uma Clínica Escola e por meio das figuras utilizadas no Protocolo de Avaliação em Motricidade Orofacial, MBGR. Os testes utilizados para a análise estatística foram "Teste de Fisher", "Qui Quadrado" e "Anova", adotando-se como nível de significância 5% (p<0,05). Resultados: das 52 crianças avaliadas, 26 (50%) apresentaram alteração do frênulo lingual. Destas, 21 (80,8%) apresentaram tônus de língua diminuído, 20 (76,9%) apresentaram língua baixa na cavidade oral e 16 (61,5%) apresentaram problemas de articulação. Quanto aos demais itens avaliados, não foram observadas diferenças estatisticamente significantes entre os grupos. Conclusão: o frênulo curto prevaleceu sobre as demais classificações da alteração do frênulo de língua. O grupo pesquisa apresentou alterações estatisticamente significantes quando comparado ao controle, nos seguintes itens: tônus lingual, postura de língua baixa na cavidade oral e articulação. Nos demais itens, apesar de não haver diferença estatisticamente significante entre os grupos, houve uma tendência de alteração maior no grupo pesquisa. Não foi possível determinar se as alterações de fala fonética são iguais para as diferentes alterações do frênulo lingual.

ABSTRACT Purpose: to characterize and compare speech alterations related to the lingual frenulum alterations in schoolchildren from 8;6 to 10;11 years old among the control and research group. Methods: 52 school children were evaluated (8;6 to 10;11 years old) both genders, regularly enrolled in private institutes divided into two groups: control group (without lingual frenulum alterations) and research group (with lingual frenulum alterations). These children were initially evaluated through the Assessment in OrofacialMotricity Protocol MBGR in a school clinic, through pictures used in this assessment. The tests used for the statistical analysis were "Fisher Test", "Qui Square" and "Anova", as significant level 5% (p<0.05). Results: from the 52 children, 26 (50%) presented lingual frenulum alteration. From these 26 children, 21 (80.8%) presented diminished lingual tonus, 20 (76.9%) presented low tongue in the oral cavity and 16 (61.5%) presented articulation alteration. Regarding the other evaluated items, there were no statistically significant differences among the groups. Conclusion: the short frenulum prevailed over the other lingual frenulum alterations classifications. The research group presented statistically significant alterations when compared with the group control, in the following items: tongue tonus, low tongue posture in the oral cavity and articulation. In the other items, although there is no statistically significant difference among the groups, there was a tendency of major alteration in the research group. It was not possible to determine if alterations in phonetics speech are the same regarding the different lingual frenulum alterations.

Many techniques have been proposed for root coverage. However, none of them presents predictable results in deep and wide recessions. OBJECTIVES: The aim of this case series report is to describe an alternative technique for root coverage at sites showing deep recessions and attachment loss >4 mm at buccal sites. MATERIAL AND METHODS: Four patients presenting deep recession defects at buccal sites (>4 mm) were treated by the newly forming bone graft technique, which consists in the creation of an alveolar socket at edentulous ridge and transferring of granulation tissue present in this socket to the recession defect after 21 days. Clinical periodontal parameters, including recession depth (RD), probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), plaque index (PI) and keratinized gingiva width (KGW) were evaluated by a single examiner immediately before surgery and at 1, 3, 6 and 9 months postoperatively. RESULTS: All cases showed reduction in RD and PD, along with CAL gain, although no increase in KGW could be observed. These findings suggest that the technique could favor periodontal regeneration along with root coverage, especially in areas showing deep recessions and attachment loss.

Most studies investigating the impact of oral contraceptives have been performed some years ago, when the level of sexual hormones was greater than the actual formulations. Objective: The aim of this study was to evaluate the effects of current combined oral contraceptives (COC) on periodontal tissues, correlating the clinical parameters examined with the total duration of continuous oral contraceptive intake. Material and methods: Twenty-five women (19-35 years old) taking combined oral contraceptives for at least 1 year were included in the test group. The control group was composed by 25 patients at the same age range reporting no use of hormone-based contraceptive methods. Clinical parameters investigated included pocket probing depth (PD), clinical attachment level (CAL), sulcular bleeding index (SBI) and plaque index (Pl.I). Data were statistically evaluated by unpaired t test, Pearson’s correlation test and Spearman’s correlation test. Results: The test group showed increased PD (2.228±0.011 x 2.154±0.012; p<0.0001) and SBI (0.229±0.006 x 0.148±0.005, p<0.0001) than controls. No significant differences between groups were found in CAL (0.435±0.01 x 0.412±0.01; p=0.11). The control group showed greater Pl.I than the test group (0.206±0.007 x 0.303±0.008; p<0.0001). No correlation between the duration of oral contraceptive intake, age and periodontal parameters was observed. Conclusions: These findings suggest that the use of currently available combined oral contraceptives can influence the periodontal conditions of the patients, independently of the level of plaque accumulation or total duration of medication intake, resulting in increased gingival inflammation.

OBJETIVO: Analisar a diferença entre os lados na atividade eletromiográfica do masseter em indivíduos adultos com oclusão dentária normal. MÉTODOS: Foram avaliados 30 indivíduos saudáveis entre 21 e 30 anos e realizou-se eletromiografia de superfície nos músculos masseteres direito e esquerdo, durante apertamento em máxima intercuspidação e mastigação habitual com uva passa. Foram computados os valores médios dos três apertamentos dentários e dos 15 segundos da mastigação habitual para cada indivíduo. Foram considerados para a análise: o lado de maior valor e o de menor valor eletromiográfico. RESULTADOS: Durante o apertamento dentário, a diferença média entre os dois lados foi de 20,0 microvolts (μV) com intervalo de confiança (95%) entre 14,0 e 26,0 μV e durante a mastigação habitual, a diferença média entre os dois lados foi de 10,3 μV com intervalo de confiança (95%) entre 6,7 e 13,8 μV. CONCLUSÃO: Houve diferença estatisticamente significante entre os lados, com relação entre eles de 24% para o apertamento dentário e de 27% para a mastigação habitual, em indiv duos adultos saudáveis.

PURPOSE: To analyze the difference between both sides of the face during the electromyographic activity of the masseter muscle in adults with normal occlusion. METHODS: Thirty healthy individuals with ages ranging from 21 to 30 years old were selected. Surface electromyography was performed on right and left masseter muscles during maximal voluntary clenching and habitual chewing with raisins. The mean values of three teeth clenching and fifteen seconds of habitual chewing were calculated for each subject. The analysis considered the sides with higher and lower electromyographic activity. RESULTS: During maximal voluntary clenching, the mean difference between sides was 20.0 microvolts (μV), with confidence interval (95%) between 14.0 and 26.0 μV. During habitual chewing, the mean difference between sides was 10.3 μV, with confidence interval (95%) between 6.7 and 13.8 μV. CONCLUSION: There was a statistically significant difference between both sides of the face in healthy adult subjects, with a relation between sides of 24% for maximal voluntary clenching and 27% during habitual chewing.

OBJETIVO: verificar a atividade elétrica do músculo masseter em pessoas com paralisia facial periférica de longa duração. MÉTODOS: participaram deste estudo seis sujeitos de ambos os sexos, com paralisia facial há pelo menos doze meses, sem queixas mastigatórias e sem disfunção temporomandibular e com pelo menos seis dentes em cada hemiarcada. Todos preencheram um questionário de anamnese e em seguida foram submetidos à eletromiografia de superfície dos masseteres de ambos os lados. As provas eletromiográficas foram: posição habitual com lábios fechados, apertamento dentário, mastigação habitual e unilateral à direita e à esquerda com uva passa. RESULTADOS: em todas as provas eletromiográficas não foram observadas diferenças significantes (p=0,05) entre os lados com e sem paralisia facial. CONCLUSÃO: observou-se com o presente estudo que a força do músculo masseter não sofre influência da paralisia facial de longa duração.

PURPOSE: to check the masseter electrical activity in long lasting facial paralysis patients. METHODS: six subjects, with facial paralysis for over a period of twelve months, males and females, took part in this study. Patients should not show any masticatory complaints or have any diagnoses of temporo-mandibular joint dysfunction, having at least six teeth in each half dental ridge. All subjects filled out a questionnaire regarding oral habits and were assessed by surface electromyography of the masseter muscle of both sides. Electromyographic records were taken with lips closed at rest, teeth tightness, besides usual mastication, and unilateral mastication on both sides with raisins. RESULTS: in all electromyographic tests there were no statistically significant differences (p=0.05) between both sides, with and without facial paralysis. CONCLUSION: it was observed that the strength of the masseter muscle is not under the influence of long lasting facial paralysis.
