Decreased masticatory function, which is termed 'masticatory dysfunction', has long been considered a sign and symptom of underlying oral diseases. Masticatory function usually improves when the underlying diseases are treated. However, in older patients with systemic diseases, persistent masticatory dysfunction may occur even after individuals receive dental treatment. In this narrative review, the authors review of the current research on masticatory dysfunction associated with systemic factors, and proposed the concept of Dysmasema - a persistent condition of masticatory dysfunction refractory to dental treatment and associated with aging and systemic factors. The rationale for the need for the new concept (i.e., Dysmasema) and the elements needed to identify Dysmasema - namely, low masticatory performance, subjective eating difficulty, and poor nutritional status - are addressed. This new proposal, which is based on clinical, epidemiological, and pathological perspectives, contributes to the precise diagnosis and treatment of older adults by linking masticatory dysfunction with systemic factors.
咀嚼功能下降，即所谓的“咀嚼功能障碍”，长期以来一直被视为潜在口腔疾病的体征和症状。当潜在疾病得到治疗时，咀嚼功能通常会改善。然而，在患有全身性疾病的老年患者中，即使个体接受了牙科治疗，仍可能出现持续性咀嚼功能障碍。在这篇叙述性综述中，作者回顾了目前关于与全身因素相关的咀嚼功能障碍的研究，并提出了“咀嚼功能障碍综合征（Dysmasema）”的概念——一种对牙科治疗难治的持续性咀嚼功能障碍状态，与衰老和全身因素相关。文中阐述了提出新概念（即咀嚼功能障碍综合征）的必要性以及识别咀嚼功能障碍综合征所需的要素，即低咀嚼性能、主观进食困难和营养状况差。这项基于临床、流行病学和病理学观点的新提议，通过将咀嚼功能障碍与全身因素联系起来，有助于对老年人进行精确的诊断和治疗。
