Proper communication between dental office and dental laboratory leads to well-designed prosthesis, satisfied clinician, and comfortable professional relationship between clinician and dental technician. The communication occurs usually through a laboratory work authorization Form containing handwritten instructions from the clinician to the dental technician, that specify the materials to be u...

Dengue fever is a major problem in many developing countries, including Indonesia. Laboratory examination is used to diagnose dengue infection and to monitor disease progression. Hematology tests, such as platelet count, are also used for timely recognition of the development of severe dengue. In primary health care centers platelet counting is typically performed manually, which is labor inten...

A preventable occupational disease, pneumoconiosis that is often widespread on to a very kind of quartz, carbon and metal dust exposed work place.The data for the prevalence of pneumoconiosis and respiratory findings among dental laboratory technician is insufficient. The aim of this study is to determine the prevalence of pneumoconiosis and respiratory findings among dental laboratory technici...

Sommerville and Davies classified the spherical triangles that can tile the sphere in an edge-to-edge fashion. However, if the edge-to-edge restriction is relaxed, there are other such triangles; here, we continue the classification of right triangles with this property begun in our earlier papers. We consider six families of triangles classified as “asymptotically obtuse”, and show that they c...

Sommerville [8] and Davies [2] classified the spherical triangles that can tile the sphere in an edge-to-edge fashion. Relaxing this condition yields other triangles, which tile the sphere but have some tiles intersecting in partial edges. This paper shows that no right triangles in a certain subfamily can tile the sphere, although multilayered tilings are possible.

VIEWPOINT F or the last several years, a Dental Laboratory Summit has been held in Chicago during the annual Chicago Dental Society Midwinter Meeting. Drs. Gordon Christensen and William Yancey spearheaded the original Summit meeting, and most recently, Dr. Burney Croll of New York has taken on the role of volunteer executive director for the group. The Summit meeting has brought together a cro...

In this study, we compared classical principal components analysis (PCA), generalized principal components analysis (GPCA), linear principal components analysis using neural networks (PCA-NN), and non-linear principal components analysis using neural networks (NLPCA-NN). Data were extracted from the patient satisfaction query with regard to the satisfaction of patients from hospital staff, whic...
