Effect of Wearing a Maxillofacial Prosthesis on Masticatory Rhythm Improvement in Mandibulectomy Patients

引用

Health 2024年第7期16卷 717-729页

作者： Xuewei Han Mihoko Haraguchi Yuka I. Sumita Marwa Ahmed Aboelez Noriyuki Wakabayashi Department of Advanced Prosthodontics Graduate School of Medical and Dental Sciences Tokyo Medical and Dental University (TMDU) Tokyo Japan Department of Partial and Complete Denture School of Life Dentistry at Tokyo The Nippon Dental University Tokyo Japan Department of Prosthodontics Faculty of Dentistry Mansoura University Mansoura Egypt

Background: Recording jaw movement rhythms in patients with jaw defects is challenging using conventional tracking devices. However, masticatory rhythm is crucial for masticatory performance and nutritional intake. This study aimed to explore the impact of using a maxillofacial prosthesis to restore masticatory rhythm in mandibulectomy patients with a novel wearable device. Methods: Twelve patients who underwent mandibulectomy and were rehabilitated with maxillofacial prosthesis were recruited. Chewing rate, cycle durations, coefficient of variation of cycle durations (CV), changing times of skin morphology on the back of the ear pinna area (SM), and masticatory performance were measured during gum chewing without and with a denture using a wearable jaw movement rhythm tracking device. A paired t-test and the Pearson correlation coefficient were used for statistical analysis. Results: The chewing rate increased by 8.6 cycles/min with dentures (P P = 0.01). The CV and SM decreased with dentures (P = 0.004 and P = 0.01, respectively). Significant correlations were found between the CV and SM without dentures (P = 0.004). Conclusion: 1. Wearing maxillofacial prostheses can improve masticatory rhythm in patients who undergo mandibulectomy with Eichner B2 occlusal supports. 2. The wearable device is available for measuring masticatory rhythm in patients with jaw defects in clinics. 3. Changing times of the skin morphology on the back of the ear pinna indicate jaw movement stability through a simpler process than the coefficient of variation of cycle durations.

Association analysis of an anti-obesity mechanism and key ripened Pu-erh tea bioactive components by mimicking human general tea drinking

Pu-erh tea， a traditional Chinese beverage， performs an anti-obesity function， but the correlation between its components and efficacy remains unknown. Here， we screened two Pu-erh teas with significant anti-obesity efficacies from 11 teas. In vitro experiments revealed that lipid accumulation in L02 cells and lipid synthesis in 3T3-L1 cells were significantly better inhibited by Tea-B than Tea-A. Further in vivo experiments using model mice revealed that the differences in chemical components generated two pathways in the anti-obesity efficacy and mechanism of Pu-erh teas. Tea-A changes the histomorphology of brown adipose tissue (BAT) and increases the abundance of Coriobacteriaceae＿UCG＿002 and cyclic AMP in guts through high chemical contents of cyclopentasiloxane， decamethyl， tridecane and 1，2，3-trimethoxybenzene， eventually increasing BAT activation and fat browning gene expression; the high content of hexadecane and 1，2-dimethoxy-benzene in Tea-B reduces white adipose tissue (WAT) accumulation and the process of fatty liver， increases the abundance of Odoribacter and sphinganine 1-phosphate， inhibits the expression of lipid synthesis and transport genes. These mechanistic findings on the association of the representative bioactive components in Pu-erh teas with the anti-obesity phenotypes， gut microbes， gut metabolite structure and anti-obesity pathways， which were obtained for the first time， provide foundations for developing functional Pu-erh tea.
