ABSTRACT
Objective@#To understand potential categories of lifestyle behaviors and its association with traditional Chinese medicine (TCM) constitution among higher vocational medical students, so as to provide reference for the physical health management of them.@*Methods@#From October to December 2022, 2 720 medical students from three higher vocational medical colleges in Anhui Province were selected by stratified cluster sampling method and were investigated with a questionnaire of lifestyle and TCM body constitution. Potential category analysis (LCA) and multiple linear regression were used to explore the relationship between potential categories of lifestyle behaviors and TCM constitutions.@*Results@#The lifestyle behavior of vocational medical students were classified into three potential categories:general health group (83.60%), smoking and drinking group (4.85%) and diet preference group (11.55%). There were significant differences in the distribution of TCM constitution types among the three groups ( χ 2=46.32, P < 0.01 ). The proportion of general health group was the higher in balanced constitution (46.39%), and the proportion of smoking and drinking type was higher in phlegm dampness (25.00%). The dietary preferences were higher in phlegm dampness (20.38%), Yin deficiency (15.92%) and damp heat (20.70%). Taking balanced constitution as a reference, the occurrence risk of phlegm and dampness in smoking and drinking type and diet preference type was 1.75 times higher (95% CI =1.09-2.77) and 1.78 times higher (95% CI = 1.26-2.49) than that in general health group ( P <0.05).@*Conclusion@#There are certain aggregation characteristics in lifestyle behaviors among higher vocational medical students, which show significant relations with TCM constitutions. Targeted intervention should be carried out according to the demographic characteristics of higher vocational medical students, potential categories of behavior and lifestyle characteristics and TCM constitutions.
ABSTRACT
Objective@# To evaluate the clinical effects of full-arch cement-retained implant-supported combined crowns and screw-retained implant-supported bridge dentures in complete or half edentulous patients. @*Methods @#A total of 25 patients with complete or partial edentulous dentures followed up for 1, 3, and 5 years in our hospital from June 2013 to June 2018 and were treated with Straumann bone horizontal implantation, cobalt-chromium stenting and cobalt-chromium porcelain restoration with cement-retained and screw-retained implant-supported fixed dental prostheses to evaluate the accumulative implant survival rate, accumulative prosthesis survival rate, mechanical complications, and biological complications in both groups. @*Results @#There were 25 complete or half edentulous patients who received 165 Straumann implants and 28 implant-supported fixed dental prostheses in this study. There were 11 cases with 69 implants in the cement group and 17 cases with 96 implants in the screw group. The accumulative implant survival rate was 100% in the cement group and 96.9% in the screw group. The accumulative prosthesis survival rate was 100% in both groups. The cumulative peri-implant mucositis rate was 23.2% in the cement group and 29.2% in the screw group, and the peri-implantitis rate was 6.8% in the cement group and 7.3% in the screw group. There was 1 case of porcelain collapse (n=1/11) and no screw of abutment loosening in the cement group and 4 cases of porcelain collapse (n=4/17) and 1 case of screw loosening in the screw group. No fracture of abutment was observed in either group. There was no difference in bone loss between the two groups in the first year (P > 0.05), and a higher rate of bone loss was found in the screw group in the third and fifth years (P < 0.05). There was no difference in the sulcus bleeding index(mSBI) between the two groups in the first year and the third year (P > 0.05) and a higher modified mSBI value in the cement group in the fifth year (P < 0.05).@*Conclusion @#The survival rates of the implant and prosthesis for cement-retained or screw-retained implant-supported fixed dental prostheses were both high, but there were more mechanical and biological complications in the traditional cobalt-chromium alloy screw-retainer group. The removal of residual adhesives must be reasonably considered when choosing the cement retention method.
