ABSTRACT
Objective:To explore the facilitating and inhibitory factors influencing the behavior of young patients to share medical electronic word-of-mouth (eWOM) on internet platforms, so as to provide insights for the improvement of healthcare quality.Methods:In May 2022, 271 undergraduate students from universities in Zhejiang province were selected by convenient sampling to survey their motivations to share eWOM with a self-designed questionnaire. Multiple regression analysis was used to examine the impact of different motivational factors on the sharing intention of young patients.Results:Only 16 respondents (5.9%) had previously published medical eWOM. Egoistic motivation, altruistic motivation, medical experience, and comment habits were significant factors that promoted patients to share eWOM, with egoistic motivation ( β=0.212, P<0.001) having the greatest impact and comment habit ( β=0.139, P=0.003) having the least impact. Distrust, low self-efficacy and involvement, perceived reluctance, and perceived uselessness were significant factors inhibiting patients from publishing eWOM. Of them, distrust ( β=-0.161, P<0.001) and perceived reluctance ( β=-0.161, P=0.001) had the greatest impact, and low self-efficacy and involvement had the least impact ( β=-0.134, P=0.003). Conclusions:To enhance the positive attitude of young patients towards sharing eWOM, it is important to focus on their personal benefits and provide high-quality healthcare experiences. Building trust among patients in the platform is crucial, and efforts should be made to reduce operational barriers. Additionally, educating and raising awareness among young patients regarding the significance and influence of healthcare reviews is important.
ABSTRACT
Objective:To analyze the commonalities and differences of " Internet plus healthcare" related policies in the eastern, central and western regions of China before and after the COVID-19 pandemic and to provide references for further improving China′s " Internet plus healthcare" policy.Methods:Collecting the policies of " Internet plus healthcare" promulgated by 31 provinces(autonomous regions, municipalities)in China from April 2018 to December 2020 on the websites of various government departments, extracting keywords based on content analysis methods, and calculating degree centralities using UCINET 6 software. A comparison of the policies of the eastern, central and western regions between the pre epidemic stage(April 2018 to December 2019)and the COVID-19 pandemic stage(January 2020 to December 2020)was carried out.Results:In the pre epidemic stage, Internet diagnosis and treatment, " Internet plus medical service price" and quality supervision were the focus of attention in all regions. But the eastern region paid more attention to the policy planning of Internet hospital operation and Internet medical application, the central region focused on the transformation and efficiency improvement of medical service process by Internet technology, and the western region paid more attention to encourage the application of telemedicine to solve the difficulty of seeing a doctor. In the pandemic stage, the " Internet plus service price" was the policy focus in all regions, mostly in medical insurance payment, and the policy difference was not obvious among the eastern, central and western regions.Conclusions:Before and after the COVID-19 pandemic, the policy of " Internet plus healthcare " promulgated by the local governments in eastern, central and western regions had different emphasis and different characteristics. Our suggestion was to improve the policy system, standardize industry supervision, strengthen information security, orderly interconnect medical insurance, and actively promote the exchange of policy experiences among the provinces.
ABSTRACT
BACKGROUND: Cranial base angle is related to the formation of sagittal dentoskeletal type, and the effect of occlusal plane or posterior occlusal plane on the formation of sagittal dentoskeletal type remains controversial. OBJECTIVE: To compare the importance of occlusal plane inclination and posterior occlusal plane inclination in determining the formation of sagittal dentoskeletal type, and to explore the combined influence of the cranial base angle and posterior occlusal plane inclination on the formation of sagittal dentoskeletal type, and its correlation. METHODS: The study was implemented in accordance with the ethical requirements of Hospital of Stomatology, Southwest Medical University. Patients and their guardians signed the informed consents. Totally 207 lateral cephalograms from patients (100 males and 107 females, aged 12-20 years) were selected. Dentoskeletal landmarks and subsequent measurements were performed and analyzed using Uceph software and SPSS 17.0 software, respectively. The samples were classified as three sagittal dentoskeletal types according to the anteroposterior dysplasia indicator (APDI) value: Class I, class II, and class III. The SNK and LSD methods were used for comparison among the three groups. The Pearson correlation coefficient analysis was used to analyze the correlation between skull base angle (NSBa angle), occlusion plane (FH-OP), posterior occlusion plane (FH-POP) and other related measurement indexes. Descriptive statistical methods were used to group occlusal plane inclination, posterior occlusal plane inclination and skull base angle, and the two-sample f-test was used to compare relevant bone and tooth indexes. Four dentoskeletal groups were established according to the posterior occlusion plane inclination and skull base angle: Small skull base angle-flat posterior occlusion plane group (S-F), small skull base angle-steep posterior occlusion plane group (S-S), large skull base angle-flat posterior occlusion plane group (L-F), large skull base angle-steep posterior occlusion plane group (L-S). Intergroup comparison was completed using crossover one-way analysis of variance. RESULTS AND CONCLUSION: The skull base angle was significantly smaller in the class III group than the class I and II group. Significantly higher posterior occlusion plane inclination was observed in the class II group than the class I and III groups. No differences were found in the APDI and ANB between occlusal plane groups. Significant differences in the ANB angle and APDI value were shown on the small skull base angle-flat posterior occlusal plane group and the large skull base angle-steep posterior occlusal plane group. These results indicate that among the factors affecting the formation of sagittal dentoskeletal type, the posterior occlusal plane is more representative than the occlusal plane. The curvature of the skull base and the inclination of the posterior occlusal plane affect the formation of sagittal dentoskeletal type. During the formation of sagittal dentoskeletal type, there may be some compensatory mechanisms between the curvature of the skull base and the posterior occlusal plane.
ABSTRACT
BACKGROUND: With the advancement of science and technology, invisible aligner without brackets have emerged. However, this new type of digital orthodontic technology is rarely reported on its biomechanics. OBJECTIVE: By the use of rectangular attachments of different sizes and different bonding positions, to obtain different force of canines and the stress supporting of periodontal tissue during the extrusion movement, providing reference for the clinical use of rectangular attachment in the orthodontic treatment of low canine tooth. METHODS: A three-dimensional finite element model of appliance-attachments-canine-periodontium-cancellous bone-cortical bone was established based on the scan data of the isolated canine. The attachments were set in different directions (vertical, horizontal), sizes (3, 4, 5 mm in height) and positions (in the occlusal side of the crown center, in the gingival side of the crown center). The 0.25-mm forced occlusal displacement was loaded to observe the deformation and equivalent stress of the tooth and periodontal membrane. RESULTS AND CONCLUSION: (1) If the size of rectangular attachment increases, the force of the tooth will grow in a certain range and the tooth will have better effect of extrusion with a larger level of tilt motion in other directions. (2) The extrusion effect of the horizontal attachment is better than that of the vertical attachment, which is more difficult to have distal incline, but is prone to lingual incline.
