Journal of Traditional Chinese Medicine 2024年第4期44卷 688-693页

作者： ZHU Xuan LOU An ZHU Keke RUAN Mingyu department of Science and Technology Hunan University of Chinese Medicine department of prosthodontics Hunan University of Chinese Medicine Affiliated Dental Hospital department of Stomatology the First Affiliated Hospital of Hunan University of Chinese Medicine School of Medicine Hunan University of Chinese Medicine

OBJECTIVE: To investigate the protective effect of the Chinese herbal formula of Jiedu Huayu decoction(解毒化瘀汤, JHD) on oral mucosa of rats with oral submucosal fibrosis(OSF) and its potential mechanism of action. METHODS: Sprague-Dawley male OSF model rats were constructed by injection of betaine and topical rubbing and were randomly grouped and administered by gavage for 4 weeks. Mouth opening and buccal mucosa scores interleukin levels and the expression of Axin and β-catenin proteins or genes were measured before and after drug administration. RESULTS: After treatment with JHD the buccal mucosal lesions of rats were significantly reduced Axin protein and mRNA expression were significantly increased β-catenin protein and m RNA expression were significantly decreased interleukin-1β and interleukin-6 levels were decreased and interleukin-10 levels were increased. CONCLUSION: The mechanism of action of JHD can effectively alleviate the pathological damage of buccal mucosa in OSF rats which may be related to the promotion of Axin expression and inhibition of β-catenin expression.

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.
