Objective:To explore the oral health status of population in Gansu Province and get scientific information for oral diseases prevention. Methods: An equal-sized stratified multi-stage random sampling design was applied in the investigation. According to standard and method used in the third national oral health epidemiological investigation, the oral health investigation was made in 3 158 people aged 5 years, 12 years, 35-44 years and 65-74 years with a gender ratio of half to half in Gansu. Results: The caries prevalence rate was 55.80%, 19.09%, 61.95% and 78.63% and the caries-filling rate was 3.11%, 10.76%,10.34% and 4.60% in the four groups respectively. Detection rates of gingival bleeding and dental calculus were 82.81%, 93.55%, 85.34% and 69.66%, 99.37%, 92.54% in 12, 35-44 and 65-74 groups respectively. Detection rates of periodontal pocket and diseases of oral mucosa were 60.94%, 62.20% and 6.32%, 7.71% in 35-44 and 65-74 groups respectively. The most denture-prosthesis was removable partial dentures and irregular fixed bridge. Conclusion: The prevalence of caries is serious but better than the average results of the nation in 2005 and the results of Gansu in 1995. The prevalence of periodontal disease is more serious than the results of the nation in 2005. It is essential to strengthen oral health education and oral health service, especially in rural area in Gansu, so as to ensure the oral diseases be treated in time and effectively.

OBJECTIVETo provide basic data for the prevention of oral diseases in minorities by investigating the oral health status and behavior related to oral health knowledge of individuals aged 35 to 44 years in Dongxiang, Bonan, and Yugur.

METHODSThe caries and periodontal health of 445 individuals aged 35 to 44 years were examined according to the method and criterion prescribed by the World Health Organization and the Third National Oral Health Epidemiologic Investigation. A questionnaire survey on related oral health knowledge and behavior was conducted.

RESULTSThe crown caries prevalence rate in Dongxiang, Baoan, and Yugur were 48.28%, 79.47%, and 67.11%, respectively; the root caries prevalence rates were 38.62%, 69.54%, and 42.95%, respectively. The rates of gum bleeding in Dongxiang, Bonan, and Yugur were 86.90%, 90.07%, and 65.77%, respectively. The rates of dental calculus in Dongxiang, Bonan, and Yugur were 99.31%, 100.00%, 99.33%, respectively, and the rates of periodontal bags were 68.97%, 67.55%, and 43.62%, respectively. Only 69.84% of the respondents brush their teeth every day; 94.90% of the respondents do not floss. Only 20.19% of the respondents contact a doctor for a toothache, and 42.23% of the respondents have never seen a dentist.

CONCLUSIONCaries morbidity is high among the respondents aged 35 to 44 years from Dongxiang, Bonan, and Yugur. The periodontal health status and oral hygiene of the respondents are poor, and behavior related to oral health knowledge is insufficient. Thus, more attention must be provided to the prevention and control of caries and periodontal diseases among middle-aged people in the area.

Objective The purpose of this study was to detect serum 25-hydroxyvitamin D [25-(OH) VitD] levels in children with atopic dermatitis (AD) and to explore its association with food allergy (FA).Methods Sixty cases of infant patients with AD have been collected.The morning fasting venous blood were obtained to check the 25-(OH)VitD level in serum.Moreover,IgE in 6 kinds of common food was also tested.Multiple regression analysis was used to analyze the relation between 25-(OH)VitD level in serum and FA.The potential risks and confounding factors were adjusted.Results Among the 60 AD children,67.4％ of them had FA,and the majority of them had milk allergy (86.84％),no wheat allergy was found.There was a positive correlation between 25-(OH) VitD levels and age (r=0.46,P＜ 0.01),but no statistical correlation with total IgE levels (P＞0.05).25-(OH)VitD deficiency may significantly increase the risk of suffering from FA (OR=11.20,95％CI:1.35-73.66,P=0.023).Conclusion The decrease of the 25-(OH)VitD level in infant patients with AD is associated with FA.What's more,25-(OH)VitD deficiency may be a risk factor for increasing FA.
