ABSTRACT
Objective To investigatethe quality of life of patients with oral cancer in different period in a hospital, and to explore the impact of patients' psychological status on their quality of life. Methods 50 cases of oral cancer patients in our hospital were investigated in this study by Convenience sampling method. The scale of the hospital anxiety and Depression Scale (HADS, the Japanese version), the quality of life of cancer patients were measured by the scale (FACT-G); the functional evaluation of tumor therapy- head and neck questionnaire (FACT-H&N). Results The comparison of HADS score between patients before and after surgery showed that the improvement of mental status was not obvious in the postoperative patients.The scores of HADS between patients before surgery and after hospital showed that the improvement of mental status was obvious (t=-2.809, P=0.01; t=-3.828, P=0.003). There were significant differences in HADS anxiety and depression-related factors between different periods (F=7.644,P=0.001;F=6.442,P=0.002);Before surgery,patients with low anxiety and depression had higher scores in both emotional and physical functional dimensions, and the difference between the two groups was statistically significant (t=7.882,5.847,6.870,7.262, P<0.05 or 0.01). The scores of the two groups were higher in the whole life quality dimension after surgery,and the difference between the two groups was statistically significant(t=3.640-7.931,P<0.01 or 0.01).There were significant differences in body function and psychological function scores between different periods(F=8.569, P=0.000; F=10.250, P=0.003). Conclusions Oral cancer patients have a higher level of anxiety and depression before and after surgery, and psychological status of patients with a certain impact on quality of life, it should be targeted for individual characteristics of patients with targeted care measures to improve the psychological status of patients,thereby improving the quality of life of patients.
ABSTRACT
Objective To investigate fracture resistance and fracture patterns of maxillary anterior endodontically treated teeth restored with two different shapes of glass fiber post systems.Methods Twenty-four human sound maxillary anterior teeth of similar size were collected,and randomly divided into 3 groups,8 teeth each.After endodontical treatment,they were given the following treatments:Group A:parallel glass fiber posts (coltene parapost fiber lux) and composite core;Group B:taper glass fiber posts (coltene parapost taper lux) and composite core; Group C (control group):intact endodontically treated teeth.Teeth in Groups A and B reserved 2 mm dentin ferrule.Then the teeth were prepared and restored with IPS e.max Press all ceramic crowns.All the teeth were embedded in acrylic resin 2 mm below the cementoenamel junction (CEJ),with the silicon impression material stimulating periodontal membrane.All the specimen were loaded under a universal testing machine,at the palatal junction of incisor third and middle third,with an angle of 135 degree to the longitudinal axis of the tooth until fracture occurred,at a cross-head speed of 1.0 mm/min.Fracture loads and patterns were recorded.Statistical analysis was performed using SPSS software.Results The mean fracture loads in the three groups were as follows:(468.8±142.5) N,(440.2±202.7) N,and (459.0±147.6) N,respectively.There was no significant difference in fracture loads among groups (P＞0.05).The incidence of unfavorable fracture in Group A was higher than Groups B and C.Conclusions There is no significant difference in fracture strength between parallel and taper fiber post groups.However,the group with parallel fiber posts demonstrates a higher risk of unfavorable fracture than the group with taper fiber posts,which indicates that taper fiber posts are more favorable to preserve the remaining tooth structure.
