This study evaluated the use of decalcified, freeze-dried bone allograft for repairing periodontal intrabony defects. 15 patients participated in the trial with 21 teeth. Following initial preparation and reevaluation, the bone defects were filled with decalcified, freeze dried bone. Patients were recalled after 1 week, 3 months and 6 months. After 6 months, significant clinical changes could be noted: mean probing pocket depth decreased from 6.2 mm to 3 mm, attachment loss decreased from 6.5 mm to 2.7mm, alveolar bone effect height increased by 2mm.

Dentonin is extracted from solanumi procumbens lour, achyranthes bidentata blunme and elutherine subaphylla gapnep. It is used in the study to treat 40 cases of acute gingivitis and periodontitis. After that, patients were asked to use dentonin as mouth rinse for 5-10 minutes 3-4 times a day. After conventional antibiotherapy was applied to the control group consiting of 40 subjects, 65% patients showed good results, 22% moderate results and 13% poor results. The material is easy to use because its low cost and so far, it does not show any side effects.

The school-based dental preventive program has been developed strongly in many areas of the whole country. Especially, the program has been covered at level of province such as Ninh Binh and Nam Dinh. It is preventive results were very high. Dental carries were reduced and periodontal status is improved. Through the study of fluoride concentration in the natural water, we determine that the use of fluoride mouthwash for children at school is necessary to reduce dental carries.

This study compares the results of two calculating methods: used hand instruments and ultrasonic machine. Forty five patients, with periodontitis participated in this study. 45 incisors were calculated by hand instruments and other 45 teeth by ultrasonic machine, and all were polished. The smothness of the teeth surfaces were graphed.The study showed that after calculating by ultrasonic machine, the teeth surfaces were more smooth than by hand instruments

Acupuncture, which is a preventive and treating method without drugs of traditional medicine, has had a long-standing history. Classical acupuncture is still the main, irreplaceable treatment method (electricity acupuncture in nature is classical acupuncture which is added by electricity into acupunctured spots). When giving the needle in patients, they will react against and have pain feeling, level of pain depends on different areas of the body, whenever receptors in skin and muscle will identify and make nervous pulses that will go to central nervous system through nerves. The second electric potential appears when acupuncturing needle into the body, that is injury electric potential. The third electric potential appears when the acupuncture needle is made of metal

Background: Forest malaria is one of the challenges faced by the Malaria Control Program in Vietnam. Objectives: (1). To evaluate the malaria prevalence among forest goers, (2). To study the efficacy of insecticide-treated hammock net (ITHNs) in malaria prevention for forest goers. Subject and method: The descriptive epidemiological intervention study on the effect of ITHNs in forest malaria control has been carried out in Ninh Thuan in 2005 \ufffd?2006. Results: Malaria prevalence among forest goers was very high: Clinical malaria: 15.5%, enlarged spleen: 7.0%, confirmed cases: 13.3% and asymptomactic cases: 74%. Age, sex, ethnic, low educated levels, low income, less use of mosquito-nets and poor house condition were considered as risk factors in malaria infection, especially for people who spent much time in the forest. ITHNs were effective in prevention of malaria infection, the malaria morbidity was decreased after 2 years of application (reduced from 31 % to 14% for prevalence, and from 274/1000 population to 161/1000 population for incidence), and the morbidity rate was lower than that in the group of people who did not use ITHNs. Conclusion: For the entomological survey, it is found that Anopheles density reduced in the group of people prevented by ITHNs. The residual of insecticide on the hammock net was decreased after 2 years utilization.\r\n', u'\r\n', u'\r\n', u'

Background: Coordinating between soldiers and people bring significant results in protecting healthy for soldiers and people in malaria epidemic area.\r\n', u'Objectives: To evaluate epidemic supervision and propose solutions protecting healthy for soldiers and people in malaria epidemic area.\r\n', u'Subjects and methods: A retrospective cross sectional study was carried out on two provinces Binh Phuoc and Dak Lak\r\n', u'Results: there was 4 main disease types were fever, tuberculosis, diarrhea and malaria. Malaria at investigated times still accounted high rate comparing with general fever rate. Malaria risk contained in people living or working in forest and mountain field; free emigrants; armed forces and border guard. These subjects needed to improve regularly protection from malaria. Communication of health education is one of important method to prevent and control malaria.\r\n', u'Conclusion: It is necessary to implement strong methods (such as providing insecticide treated bed nets, indoor residual spray) to prevent and control malaria. \r\n', u'

Background: The vulnerability to contract malaria was researched among the Raglai ethnic minority population living in the mountainous areas of Ninh Thuan province, South-central Viet Nam, one of the areas with highest incidence rates in the country. Objective: To investigate the bed net use, risk perception of contracting malaria in Raglai ethnic minority. Subject and Method: The study used qualitative and quantitative method and was carried out in Ninh Thuan from 8/2005 to 8/2006. Result: Raglai exposure to malaria was related to farmers' forest activity and forest sleep which were directly related to the combination of sleeping and living in a government supported home in newly established villages along the road with a second home or reduced plot hut near fields in the forest to meet work requirements during the labor intensive malaria transmission and rainy season. In this context, access to health care, bed net use, risk perception of contracting malaria and health seeking behavior were researched. Conclusion: The results of the study do not only show the vulnerability of an impoverished ethnic minority population but as well the urgent need to better understand ethnic minorities' social context and culture to improve malaria control strategies.

Objectives: The association between body composition parameters and peak bone mineral density is not well documented. The aim of this study is to assess the relative contributions of lean mass and fat mass on peak bone mineral density (BMD). Methods: The study involved 416 women and 334 men aged between 20 and 30 years who were participants in the population-based Vietnam Osteoporosis Study. Whole body composition parameters (eg, fat mass and lean mass) and BMD at the lumbar spine and femoral neck were measured by dual-energy X-ray absorptiometry. The association between lean mass and fat mass and BMD was analyzed by the linear regression model using the Least Absolute Shrinkage and Selection Operator (LASSO). Results: Peak BMD in men was higher than women, and the difference was more pronounced at the femoral neck (average difference: 0.123 g/㎠; 95% confidence interval [CI] 0.105–0.141 g/㎠) than at the lumbar spine (average difference 0.019 g/㎠; 95% CI, 0.005–0.036 g/㎠). Results of LASSO regression indicated that lean mass was the only predictor of BMD for either men or women. Each kilogram increase in lean mass was associated with ∼0.01 g/㎠ increase in BMD. Lean mass alone explained 16% and 36% of variation in lumbar spine and femoral neck BMD, respectively. Conclusions Lean mass, not fat mass, is the main determinant of peak bone mineral density. This finding implies that good physical activity during adulthood can contribute to the maximization of peak bone mass during adulthood.
