“…Clinical observations and research indicate that mere fabricating dental prosthesis to manage or rehabilitate edentulism does not necessarily guarantee automatic improvement of patient's sensory and motor function, or successful adaptation to the new sensorimotor condition . Lack of simple and clinically viable methods for subjective evaluation or use of non‐standardised methods across different studies makes it difficult to compare and quantify the magnitude of the problem . Further, studies have shown discrepancies in chewing efficiency and impaired sensorimotor control associated with people rehabilitated with dental prosthesis .…”

Tooth loss, decreased mass and strength of the masticatory muscles leading to difficulty in chewing have been suggested as important determinants of eating and nutrition in the elderly. To compensate for the loss of teeth, in particular, a majority of the elderly rely on dental prosthesis for chewing. Chewing function is indeed an important aspect of oral health, and therefore, oral rehabilitation procedures should aim to restore or maintain adequate function. However, even if the possibilities to anatomically restore lost teeth and occlusion have never been better; conventional rehabilitation procedures may still fail to optimally restore oral functions. Perhaps this is due to the lack of focus on the importance of the brain in the rehabilitation procedures. Therefore, the aim of this narrative review was to discuss the importance of maintaining or restoring optimum chewing function in the superageing population and to summarise the emerging studies on oral motor task performance and measures of cortical neuroplasticity induced by systematic training paradigms in healthy participants. Further, brain imaging studies in patients undergoing or undergone oral rehabilitation procedures will be discussed. Overall, this information is believed to enhance the understanding and develop better rehabilitative strategies to exploit training-induced cortical neuroplasticity in individuals affected by impaired oral motor coordination and function. Training or relearning of oral motor tasks could be important to optimise masticatory performance in dental prosthesis users and may represent a much-needed paradigm shift in the approach to oral rehabilitation procedures.

“…A literatura mostra que indivíduos com dentição natural saudável apresentam índices máximos no desempenho mastigatório e os indivíduos com PTR bimaxilar apresentam índices mínimos. Entretanto, estes valores podem variar dependendo do estado da dentição e do tratamento reabilitador realizado (Neves, 2015). Nesta pesquisa, houve maior número de ciclos mastigatórios em pacientes com menor número de elementos dentários presentes, semelhante ao estudo de Campos (2019).…”

Objetivo: Avaliar em graus os distúrbios miofuncionais orofaciais e cervicais de adultos e idosos e avaliar a função mastigatória antes e após a reabilitação protética. Método: Trata-se de um estudo de intervenção com natureza quantitativa, utilizando o software e-Myo para avaliação miofuncional associado ao teste de limiar de deglutição para avaliação da função mastigatória. O estudo foi realizado com 20 (vinte) participantes divididos em dois grupos: G1 composto por 10 (dez) adultos e G2 composto por 10 (dez) idosos, sendo estruturado em duas etapas: na primeira etapa, foi realizada avaliação miofuncional e teste do limiar de deglutição na condição bucal existente; na segunda etapa, foi executada a reabilitação protética com confecção de próteses totais e/ou parciais removíveis e, após trinta dias da instalação das próteses, foi realizada uma segunda avaliação miofuncional, bem como o segundo teste do limiar de deglutição. Resultados: Em relação às avaliações miofuncionais, 3 (três) participantes do grupo de adultos e 5 (cinco) do grupo de idosos não apresentaram alteração no grau de classificação geral. 1 (um) participante do grupo de adultos apresentou alteração com impacto negativo no grau geral. Constatou-se redução no limiar de deglutição nos dois grupos após reabilitação protética, com índices maiores no grupo de adultos. Conclusão: Houve maior número de ciclos mastigatórios em pacientes com menor número de elementos dentários presentes, com uma melhora no grau geral de classificação dos distúrbios miofuncionais. Constatou-se redução do Limiar de Deglutição nos 2 (dois) grupos após reabilitação protética, com índices maiores no grupo de adultos.

“…Despite the studies included in this review did not report the location of missing teeth, several studies assessing the incidence of tooth loss have demonstrated that the posterior occluding units are the most affected and the front teeth the least affected (Montandon et al, 2012; Minja et al, 2016); being premolars less affected than molars (Silva-Junior et al, 2017), and this may interfere in the prediction of MD. Thus, future studies should include the location of missing teeth in dental records, considering that the presence of three to four premolars can still provide good mastication function, as well as the presence of removable full or partial dentures (Zhang et al, 2019), fixed dentures and implants (Prithviraj et al, 2014; Neves et al, 2015).…”

Masticatory Dysfunction by Extensive Tooth Loss as a Risk Factor for Cognitive Deficit: A Systematic Review and Meta-Analysis

et al. 2019

Background: An amount of cognition decline is normal with aging; however, intrinsic and extrinsic risk factors may exacerbate it, affecting social and occupational tasks. Masticatory dysfunction (MD), as a general term, refers to an impairment in the masticatory function triggered by a structural factor, such as tooth loss; functional factors, such as weaker bite force or a poorer masticatory performance; or both factors. MD acting as a source of chronic stress, promotes functional and morphological changes on the hippocampus, a brain area crucial for learning and memory abilities. This study aimed to synthesize evidence on the association between MD and cognitive deficit (CD), and demonstrate whether might be adequately considered as a risk factor. Methods: Observational studies were screened in seven online databases; the search strategy (PECO) was focused in observational studies with humans as a population (P), presenting groups exposed (E), and non-exposed (C) to tooth loss, in which cognition parameters were measured and compared between groups (O). The final selection included only those studies comparing the effect in cognition between subjects having ≥20 remaining teeth and <20 remaining teeth, considering the latter as a structural factor triggering MD by the literature. Searching and data extraction were conducted following PRISMA guidelines. Qualitative and risk of bias evaluations were performed. The meta-analysis (MA) was constructed including the odds ratio (OR) and its 95% confidence interval (CI) comparing two groups—with/without MD. The level of evidence was rated by Grading Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: In total, 5,666 citations were identified, 14 accomplished our eligibility criteria, and nine were include in the MA. The MA demonstrates that individuals with MD had 46% higher chance to presented CD (OR 2.24 [1.73, 2.90], p < 0.00001, I 2 = 46%). The level of evidence was rated as low by GRADE. Conclusion: Despite the low certainty in evidence, according to our MA, MD is positively associated with increased risk of CD. However, more studies including other factors underlying MD and similar measurements should be conducted to obtain a strong estimate of the risk.
