          Abstract

          RESUMO Objetivo: caracterizar a amplitude e a velocidade dos ciclos mastigatórios avaliados por eletrognatografia em um grupo de indivíduos idosos e confrontar esses dados com outros dois grupos de sujeitos com doença de Parkinson (DP) diferenciados pela característica motora predominante. Métodos: os 42 participantes foram divididos em três grupos: A com 15 voluntários e média de idade de 62 anos, sendo 8 do sexo feminino; B com 14 voluntários Parkinsonianos com rigidez predominante e média etária de 58 anos, dos quais 7 eram mulheres; e o grupo C com 13 voluntários, com DP e tremor predominante, com média de idade de 64 anos, sendo 4 mulheres. Empregou-se o teste ANOVA para diferença de médias, com contraste post-hoc de Dunnett ou teste t de Student, todos em nível de significância de 0,05. Resultados: houve maiores diferenças entre as medias dos grupos A e B no numero total de ciclos mastigatórios (A= 23,13 ± 1,41 B=18,21 ± 1,70) [p=0,034] e nas amplitudes máxima de abertura de boca (A= 34,66 ± 2,04 B=26,72 ± 2,49) [p=0,018], lateralização para direita (A=7,02 ± 0,59 B=5,80 ± 0,97) [p=0,036] e para esquerda (A=6,44 ± 0,64 B=3,35 ± 0,80) [p=0,039]. Conclusão: tendo o grupo de idosos superado as medias, na movimentação mandibular durante a mastigação, do grupo de parkinsonianos com rigidez significativamente. Podemos concluir que, é provável que fatores como a rigidez parkinsoniana possam comprometer a mastigação de indivíduos com a doença de Parkinson.

          ABSTRACT Purpose: to characterize the amplitude and speed of masticatory cycles evaluated by electrognathography in one group of elder individuals and to compare these data with those of two other groups of Parkinson's disease subjects. Methods: 42 volunteers participants in this study were divided into three groups: A with 15 volunteers, average age of 62 years, 8females, B with 14 volunteers characterized by a Parkinson’s hypokinesia, average age of 58 years, of which 7 are female, and C with 13 volunteers characterized by a Parkinson’s tremor, with average age of 64 years, being 4 female. It was used the ANOVA test for difference of means with post-hoc Dunnett's contrast or Student's t-test, all at 0.05 significance level. Results: there were greater differences between the means of groups A and B in the total number of masticatory cycles (A = 23.13 ± 1.41 B = 18.21 ± 1.70) [p = 0.034] and in the maximum mouth opening amplitudes (A = 34.66 ± 2.04 B = 26.72 ± 2.49) [p = 0.018], lateralization to the right (A = 7.02 ± 0.59 B = 5.80 ± 0.97) P = 0.036] and left (A = 6.44 ± 0.64 B = 3.35 ± 0.80) [p = 0.039]. Conclusion: the elderly group exceeded the means, in the mandibular movement during chewing, of the rigid group of parkinsonians. We may conclude that factors such as parkinsonian stiffness are likely to compromise the chewing of individuals with Parkinson's disease.

          Mechanisms of oral-pharyngeal dysphagia in patients with Parkinson's disease.

          Oral-pharyngeal dysphagia in Parkinson's disease is well recognized. The aim of this study was to establish the mechanisms of oral-pharyngeal dysphagia in these patients. Using simultaneous videoradiography and pharyngeal manometry, we studied 19 patients with Parkinson's disease (12 with oral-pharyngeal dysphagia and 7 without oral-pharyngeal dysphagia) and compared them with 23 healthy controls. the clinical severity of Parkinson's disease predicted neither the presence nor the severity of dysphagia. Minor alterations in oral function were common in controls and patients, but pharyngeal dysfunction was significantly more prevalent in patients. Incomplete upper esophageal sphincter (UES) relaxation was present in 4 patients (21%), all of whom showed increased hypopharyngeal intrabolus pressure, but not all of whom had a diminished UES opening. The patients had a reduced UES diameter (P = 0.004) and a higher intrabolus pressure compared with the controls (P = 0.007). Pharyngeal contraction pressures were lower in patients, but 6 patients with dysphagia and an abnormal pharyngeal wall motion had normal peak pressures. An incomplete UES relaxation and a reduced UES opening, both associated with high intrabolus pressure, are prevalent in Parkinson's disease. Oral-pharyngeal dysphagia in Parkinson's disease is multifactorial, with the majority of patients showing oral and pharyngeal dysfunction, even before the clinical expression of dysphagia. Impaired pharyngeal bolus transport is the major determinant of dysphagia.

            Orofacial function and oral health in patients with Parkinson's disease.

            No comprehensive study has previously been published on orofacial function in patients with well-defined Parkinson's disease (PD). Therefore, the aim of this study was to perform an overall assessment of orofacial function and oral health in patients, and to compare the findings with matched control subjects. Fifteen outpatients (nine women and six men, 61-82 yr of age; Hoehn & Yahr Stages 2-4; and with motor impairment ranging from 17 to 61 according to the Unified Parkinson's Disease Rating Scale, Objective Motor Part III) were examined in their 'on' state together with 15 age- and gender-matched controls. Orofacial function and oral health were assessed using the Nordic Orofacial Test, masticatory ability, performance and efficiency, oral stereognosis, jaw opening, jaw muscle tenderness, the Oral Health Impact Profile-49, number of natural teeth, and oral hygiene. Orofacial dysfunction was more prevalent, mastication and jaw opening poorer, and impact of oral health on daily life more negative, in patients with PD than in controls. The results indicate that mastication and orofacial function are impaired in moderate to advanced PD, and with progression of the disease both orofacial and dental problems become more marked. It is suggested that greater awareness of the special needs in PD patients and frequent dental visits are desirable to prevent dental diseases and decay and to support masticatory function. © 2011 Eur J Oral Sci.

              Co-ordinated mandibular and head-neck movements during rhythmic jaw activities in man.

              Recent observations in man of concomitant mandibular and head movements during single maximal jaw-opening/-closing tasks suggest a close functional relationship between the mandibular and the head-neck motor systems. This study was aimed at further testing of the hypothesis of a functional integration between the human jaw and neck regions. Spatiotemporal characteristics of mandibular and associated head movements were evaluated for 3 different modes of rhythmic jaw activities: self-paced continuous maximal jaw-opening/-closing movements, paced continuous maximal jaw-opening/-closing movements at 50 cycles/minute, and unilateral chewing. Mandibular and head-neck movements were simultaneously recorded in 12 healthy young adults, by means of a wireless opto-electronic system for 3-D movement recordings, with retro-reflective markers attached to the lower (mandible) and upper (head) incisors. The results showed that rhythmic mandibular movements were paralleled by head movements. An initial change in head position (head extension) was seen at the start of the first jaw-movement cycle, and this adjusted head position was retained during the following cycles. In addition to this prevailing head extension, the maximal jaw-opening/-closing cycles were paralleled by head extension-flexion movements, and in general the start of these head movements preceded the start of the mandibular movements. The results support the idea of a functional relationship between the temporomandibular and the cranio-cervical neuromuscular systems. We therefore suggest a new concept for human jaw function, in which "functional jaw movements" are the result of activation of jaw as well as neck muscles, leading to simultaneous movements in the temporomandibular, atlanto-occipital, and cervical spine joints.
