Abstract
Background/purpose
Chewing difficulty can contribute to psychological stress, which reduces the quality of life for older adults. The purpose of this study was to investigate and analyze the severity of masticatory discomfort, stress response, and sleep disturbance in older patients experiencing masticatory discomfort due to tooth loss or temporomandibular disorders (TMD), to find the further treatment direction for these patients.
Materials and methods
A total of 392 patients aged 50 years and older with mastication difficulties were analyzed. Two group of patients, those seeking prosthetic treatment due to tooth loss (n = 193) and those who were referred due to TMD-related pain discomfort (n = 199), were identified. Numeric rating scale (NRS), stress response inventory (SRI), and insomnia severity index (ISI) were used as tools to measure patients’ subjective chewing discomfort, stress response, and sleep status.
Results
Chewing discomfort and age were found to be much higher in the prosthetic group than in the TMD group. The TMD group had significantly higher scores in five SRI parameters (tension, anger, depression, fatigue, and frustration) as well as total score and a higher percentage of clinical insomnia compared to prosthetic patients.
Conclusion
Since the number of remaining teeth has a significant impact on the masticatory discomfort severity, restoring the occlusion through prosthodontic treatment is important to improve masticatory function. In patients with TMD, it is necessary to assess stress response and sleep quality, and a multidisciplinary treatment approach may be necessary to effectively address masticatory discomfort.
期刊介绍：
he Journal of Dental Sciences (JDS), published quarterly, is the official and open access publication of the Association for Dental Sciences of the Republic of China (ADS-ROC). The precedent journal of the JDS is the Chinese Dental Journal (CDJ) which had already been covered by MEDLINE in 1988. As the CDJ continued to prove its importance in the region, the ADS-ROC decided to move to the international community by publishing an English journal. Hence, the birth of the JDS in 2006. The JDS is indexed in the SCI Expanded since 2008. It is also indexed in Scopus, and EMCare, ScienceDirect, SIIC Data Bases.
The topics covered by the JDS include all fields of basic and clinical dentistry. Some manuscripts focusing on the study of certain endemic diseases such as dental caries and periodontal diseases in particular regions of any country as well as oral pre-cancers, oral cancers, and oral submucous fibrosis related to betel nut chewing habit are also considered for publication. Besides, the JDS also publishes articles about the efficacy of a new treatment modality on oral verrucous hyperplasia or early oral squamous cell carcinoma.
