BACKGROUND We aimed to assess the oral health status and risk factors for dental caries and periodontal disease among Sudanese adults resident in Khartoum State. To date, this information was not available to health policy planners in Sudan. METHODS A descriptive population-based survey of Sudanese adults aged ≥ 16 years was conducted. After stratified sampling, 1,888 adult patients from publ...
BACKGROUND Dental caries remains a public health problem even though it is preventable. There are several risk factors that relate to dental caries, especially in children in suburban and rural areas, where they normally receive their first dental examination in primary schools by teachers or health care personnel. Their oral health depends primarily on their parents' awareness. OBJECTIVE To ...
This study investigated the oral problems occurring in children receiving treatment for malignant disease at a regional oncology center. Forty-three children 2 to 14 years old were followed longitudinally from initial diagnosis for periods ranging from eight to 30 weeks for the development of oral and dental problems. Fifteen children had untreated decay; two required the removal of primary tee...
We have measured the angular correlation of the pair nucleons np and nn emitted from the nonmesonic weak decay (NMWD) of 12 Λ C produced via the (π +,K+) reaction in coincidence measurement. The Λp → np and Λn → nn modes were clearly identified by measuring the back-to-back correlation of the emitted nucleon pairs which is the characteristic of two-body kinematics. From the measured nucleon pai...
