ABSTRACT
Objective: To investigate the clinical perspectives of 3dMD photography in orthodontics. Methods: 60 patients with skeletal Ⅰ malocclusion (30 males, 30 females, aged 18 to 35 years) were selected. Facial pictures of them were taken by 3dMD photography and traditional photography respectively, photographing time was recorded. Facial measurements' quality data were analyzed by SPSS 16. 0. Results: The photographing time of the 3dMD group and traditional photographic group was(14. 99 ± 1. 34) s and (45. 33 ± 7. 75) s respectively(P＜ 0. 05); there was no significant difference between the 2 groups in the quality scores. Conclusion: The clinical use of 3dMD in patients can save the operation time and can get similar by the use of results traditional radiography.
ABSTRACT
Objective:To study 3-dimensional facial soft tissue reference values of Chinese Han nationality adults with normal occlusion and explore the facial morphology differences between men and women.Methods:3dMD images from 30 men and 32 women of Han nationality,aged 18-35 years,with normal occlusion were analyzed and compared between the men and women on 19 linear distances,8 angular measurements and 10 linear distance ratios.Results:Linear distances concerning the width and height of facial and organic contours were larger in men(P<0.05),while the ratio of facial height to width were larger in women(P<0.05);the nasofrontal angle and nasal prominence angle were both smaller(P<0.05) but nasofacial angle were larger(P<0.05) in men than in women.Conclusion:The facial and organic contours are larger in men than in women.Men have wide-elliptical face while women have thin-elliptical one.The nose of men is more prominent than women.
ABSTRACT
Objective To observe the therapeutic effectiveness of valsartan in combination with amlodipine in therapy of essential hypertension and the consequent changes in red cell distribution width (RDW).Methods One hundred and ten patients of hypertension were selected,then randomly divided into treatment group (56 cases) and control group (54 cases).Valsartan and amlodipine were given to the treatment group,while the control group taking amlodipine only.Bp and RBC were carried out before and after treatment.Results Antihypertensive effect of the treatment group were statistically significant compared with the control group (P ＜ 0.05).The consequent RBC,Hct and Hb,RDW level of treatment group decreased dramatically compared with the control group (P ＜ 0.01 or ＜ 0.05).Conclusions Valsartan in combination with amlodipine in ther apy of hypertension is a prospective combination which achieves superior blood pressure control,low level of RDW and blood viscosity,as a result reducing the incidence of cardiovascular events.
