ABSTRACT
Objective@#To evaluate ten year changes in deciduous teeth health and oral health behavior aged 5 year old children in Hainan province (during the year of 2005-2015), to provide basis for oral health promotion among 5 year old children in Hainan province.@*Methods@#Through the comparison and analysis of the third and the fourth national oral health epidemiology survey,changes of dental caries prevalence rate, dietary habit, oral health behavior, and health seeking behavior were analyzed.@*Results@#The prevalence of dental caries in 2005 was 76.1%, 2015 was 82.3% which had significant difference(χ2=6.23，P<0.05), the percentage of consuming sugary food and sweet drinks every day in 2005 was 13.4% and 6.1%, which increased to 30.0% and 7.4% respectively in 2015. The percentage of drinking milk and yoghurt with sugar was 47.6%, which decreased 36.5% in 2015 (χ2=12.76，P<0.05), the percentage of consuming sugary food and sweet drinks before going to bed in 2005 was17.8%, which decreased to 13.3% in 2015 (χ2=32.27，P<0.05). The percentage of brushing the teeth two or more times a day was 16.9%, which increased to 24.2% in 2015(χ2=20.50，P<0.05). The percentage of using fluoridated toothpaste decreased from 31.7% (2005) to 7.4% (2015) (χ2=229.13，P<0.05). No need to treatment for baby teeth and afraid of pain among children were the main reason for no health-seeking among parents which children of dental health problems,which deffered significantly between 2005 and 2015(χ2=6.05，9.34，P<0.05).@*Conclusion@#Children’s oral health behavior improved, while eating habits fluoridated toothpaste usage and health seeking behavior remain poor.Health education on child oral health should be strengthened.
ABSTRACT
Objective@#To evaluate the changes of oral health status and oral health behavior among 12 year old children in Hainan province during 2005-2015, to provide basis for child oral disease prevention.@*Methods@#Through the third and fourth national oral health epidemiology survey, changes in dental caries prevalence rate, dietary habit, oral health behavior, medical care in 12 year old chirdren were analyzed.@*Results@#The percentage of dental caries in permanent, gingival blleeding, dental calculus of 12 year old chirdren in 2005 was 49.9%, 63.2%, 31.5% respectively, which 57.0%, 46.8%, 39.5% respectively in 2015( χ 2=6.78, 36.78, 9.45, P<0.05). The percentage of sugary snacks,drink and milk consumption every day in 2005 was 31.0%, 13.1%, 21.8% respectively, which increased to 40.3%, 27.5%, 30.8% in 2015(χ2=11.53, 38.76, 12.73, P<0.05). 49.3% children had a toothache in 2005, which increased 58.8% in 2015(χ2=23.43, P<0.05).@*Conclusion@#The prevalence of dental caries in permanent teeth of 12 year old children in Hainan was high, while eating habits was poor and oral health behavior was showed significant improvement. Oral health education for 12 year old should be strengthened.
ABSTRACT
@#Objective To compare video-assisted thoracic surgical technique (VATS) and conventional surgical technique (CSM) in mitral valve replacement (MVR). Methods We retrospectively analyzed clinical data of 93 patients in our hospital with mitral valve replacement between January 2010 and January 2015. The patients were divided into two groups including a VATS group and a CSM group.There were 43 patients with 25 males and 18 females at age of 57.43±5.65 years in the VATS group, and 50 patients with 27 males and 23 females at age of 56.40±6.32 years in the CSM group.The clinical outcomes of the two groups were compared. Results There was no mortality. Echocardiography was normal in both groups during 1-year follow-up. There was no significant difference between the two groups in the operative time, aortic clamping time, cardiopulmonary bypass (CPB) time, or ventilation time. As compared with the CSM group, the patients in the VATS group had a significantly lower complication rate, shorter chest incision length (5.23±1.36 cm vs. 18.21±3.89 cm), less blood transfusion (1.75±0.25 U vs. 3.15±1.50 U), less chest drainage (202.34±12.12 ml vs. 412.32±21.56 ml) and lower pain score (1.26±0.86 vs. 3.01±1.13), shorter time of postoperative hospital stay (8.20±2.36 d vs. 12.10±3.26 d). Conclusion MVR under VATS is not only technically feasible, but also with excellent clinical results.
