“…These tests rely less on the crushing and comminution of the test food, but more on the bolus forming and kneading . Therefore, these tests are not highly dependent on the maximum bite force, as the specimens are more deformable and often soft, but rather on the force, coordination and sensitivity of the soft tissues (eg, the tongue, palate and cheeks) that are affected by ageing itself, diminished capability of adaptation to the dentures and poor mandibular denture retention . Of course, the structures are less, if at all, affected by any implant therapy designed to stabilise the denture; consequently, these tests often fail to demonstrate a short‐term (up to 1 year) effect on chewing efficiency .…”

Summary Objectives The aim of this study was to test the effect of a single‐implant mandibular overdenture (SIMO), compared with conventional complete denture (CD), on masticatory performance measured by the mixing ability of a two‐coloured chewing gum. Methods A sample of edentulous subjects was randomly assigned to the SIMO (n = 15) and CD (n = 19) groups. Patients in both groups received a set of new complete dentures, and the SIMO group received a single implant in the symphyseal region of the mandible (Straumann® Standard Plus SLActive®) and an eliptical matrix and ball attachment for denture retention. Masticatory tests were performed using a two‐colour chewing gum (Vivident Fruitswing, Perfetti van Melle, Turkey) for 20 and 50 chewing cycles. Colour‐mixing ability was assessed by electronic colourimetric analysis (ViewGum©, Dhal Software, Greece), expressed by the variance of hue. Tests were performed at baseline and at the 6‐ and 12‐month follow‐ups. Multilevel linear regression was used to model the changes in masticatory performance. Results Groups were similar at baseline for 20 and 50 cycles (P > 0.05). A significant linear effect was observed on time points for 20 and 50 cycles (P < 0.001). No difference was observed between treatment groups factor (P > 0.05). However, the way masticatory performance varied according to time points differed in the CD and SIMO groups for 20 cycles (P = 0.048). Conclusion Masticatory performance improved significantly after 12 months, irrespective to the insertion of a single implant to retain a mandibular overdenture. Moreover, results suggest that SIMO treatment may perform better than CD in the shorter follow‐up period.

“…The difficulty or absence of tongue elevation is highlighted, since it represents approximately 25% of the sample. This tongue mobility deficit seems to be associated with an important milestone for orofacial functions in the elderly: the presence of sarcopenia, considered to be a condition in which muscular strength is insufficient to perform daily life activities (30) . According to the size and shape of an intraoral bolus of food, the tongue needs adequate strength, agility, and sensitivity (29) , which reinforced that nutritional and physical characteristics must be taken into account in the tongue's aging process in order to avoid mainly dysphagia (30) .…”

RESUMO Objetivo conhecer as características orofaciais de idosos funcionalmente independentes e analisar a associação com a idade, gênero, nível socioeconômico e estado dentário. Método estudo observacional, transversal de caráter analítico com amostra não probabilística. Foi aplicado o instrumento validado “Protocolo de Avaliação Miofuncional Orofacial com Escalas para Idoso” em sujeitos funcionalmente independentes com idade igual ou acima de 60 anos, em boas condições de saúde segundo avaliação geriátrica padronizada, intitulada Protocolo de Avaliação Multidimensional do Idoso. Resultados os idosos apresentaram padrões de normalidade acima de 60% nos parâmetros de aspecto e mobilidade das estruturas. As alterações significantes foram: sulco nasolabial acentuado; bochechas flácidas ou arqueadas; vedamento labial com tensão ou ausência de vedamento e comissuras labiais deprimidas. As alterações de mobilidade foram pequenas, entre 20,6% e 33,8%, com maior prevalência na elevação da língua e lateralização do ar em bochechas infladas e da mandíbula. Não houve relação destes achados perante a progressão da idade e as classes socioeconômicas. As mulheres apresentaram maior chance de exibirem aspecto normal dos lábios e alguma alteração da mobilidade. O número de dentes associou-se com o volume e a configuração dos lábios e a mobilidade da mandíbula. Além disso, o uso de prótese dentária associou-se significativamente com o aspecto do sulco nasolabial e a tensão/configuração das bochechas. Conclusão este trabalho sugere que o sistema oromiofacial encontra-se dentro dos padrões de normalidade na maioria dos idosos funcionalmente independentes. O que ampara a atuação multiprofissional na prevenção, promoção e tratamento da saúde oromiofuncional dos idosos.

“…If oral tongue function is impaired, patients will have difficulties with oral control and bolus transport, increasing the likelihood for aspiration [6–8]. Decreased maximum isometric lingual pressures, or pressures produced when the oral tongue is pushed as hard as possible against the hard palate, have been documented in patients with dysphagia [9–13]. Measures of tongue endurance, or maintenance of a percentage of maximal tongue pressure, reduce as well [14].…”

Effects of Change in Tongue Pressure and Salivary Flow Rate on Swallow Efficiency Following Chemoradiation Treatment for Head and Neck Cancer

Purpose Patients treated with chemoradiation for head and neck cancer frequently develop dysphagia. Tissue damage to the oral tongue causing weakness and decreases in saliva production may contribute to dysphagia. Yet, effects of these variables on swallowing-related measures are unclear. The purpose of this study was (1) to determine effects of chemoradiation on tongue pressures, as a surrogate for strength, and salivary flow rates and (2) to elucidate relationships among tongue pressures, saliva production, and swallowing efficiency by bolus type. Methods and Materials 21 patients with head and neck cancer treated with chemoradiation were assessed before and after treatment and matched with 21 healthy control participants who did not receive chemoradiation. Each participant was given a questionnaire to rate dysphagia symptoms. Videofluoroscopic evaluation of swallowing was used to determine swallowing efficiency; the Saxon test measured salivary flow rate; and the Iowa Oral Performance Instrument (IOPI) was used for oral tongue maximum and endurance measures. Results Results revealed significantly lower tongue endurance measures for patients post-treatment as compared to controls (p=.012). Salivary flow rates also were lower compared to pre-treatment (p=.000) and controls (p=.000). Simple linear regression analyses showed that change in salivary flow rate was predictive of change in swallow efficiency measures from pre- to post-treatment for 1mL thin liquid (p=.017), 3mL nectar-thick liquid (p=.026), and 3mL standard barium pudding (p=.011) boluses. Conclusions Based on these findings, it appears that chemoradiation treatment affects tongue endurance and salivary flow rate and these changes may impact swallow efficiency. These factors should be considered when planning treatment for dysphagia.
