The aim of this study was to identify the most frequent yeasts in the oral cavity of adult individuals without immune disorders and to associate the presence of these oral yeasts with different characteristics of each individual. Oral rinse samples were obtained from 96 healthy adults and cultured in Sabouraud dextrose agar media and CHROMagar. Yeasts were identified by sequencing the D1/D2 region of the 28 S rRNA gene. Probable association among the socio-demographic characteristics, body mass index, family and personal medical history,oral hygiene, tobacco and/or alcohol consumption habits and presence of oral fungi was analyzed. Contingency tables and logistic regression were employed to evaluate possible relationships between the presence of oral fungi and mixed colonization with these variables. 57.3% of the healthy individuals had oral yeasts and 21.8% had mixed colonization. The most prevalent yeasts were Candida albicans(52%), C. parapsilosis(17.9%), and ***(7.57%). Yeasts with most frequently mixed colonization were C. albicans and C. parapsilosis. No relationships were found among the variables analyzed. However, the presence of mixed colonization was related to the presence of dental prostheses(P<0.006), dental apparatuses(P=0.016) and O’Leary index(P=0.012). This is the first study that characterized oral yeasts in Colombian healthy individuals, determined the most prevalent oral yeasts C. albicans, C. parapsilosis and C. dublinensis and an association of mixed colonization with the use of dental prostheses and aparatology and poor hygiene.

本项目的目的是在有相同几何特性的仪器上用新的R相热处理研究对扭应力和循环疲劳的抗力。研究选用尺寸为#30/.04和#30/.06的K3XF和K3锉(每组10把)。为了评估抗扭强度要记录在屈服点、极限点和断裂点的扭力载荷和扭角。直到断裂的韧性是计算的。用确定每台仪器结束时的周期数来估算循环疲劳抗力。用非参数惠特尼U检定(对扭转抗力)和独立的t试验(对循环疲劳)进行统计分析。经扭转和循环疲劳测试后,在扫描电镜下观测所有的断口评估断裂表面的断口形貌。虽然K3XF和K3显示优良的循环抗力,根据极限强度、断裂角和不考虑仪器的锥形体在K3XF和K3的两个标记之间的韧性,扭转抗力没有明显的差别。断裂横截面的表面呈现典型的循环疲劳断口和扭转断口。K3XF的独特的表面上有许多不规则微孔。采用R相热处理工艺的热处理K3XF的仪器,如果不降低扭转强度此仪器能提高循环疲劳抗力。
