Abstract Cementing operations in Arctic environments continue to require research on many unanswered problems. Laboratory studies and observation of field practices helped answer some of these questions. Areas of laboratory study were:electrical resistivities of neat and drilling mud contaminated cement.stability of

Cementing v. not cementing the Monk endoprosthesis
Injury, 1982In a retrospective study, 45 patients who had Monk hard-top endoprostheses inserted with cement because of fresh intracapsular fracture of the femoral neck, were compared with 61 patients with uncemented prostheses. The average age, age-distribution and the preoperative condition of the patients were well matched in the two groups.

Does "cement disease" exist? The bony environment surrounding a loosened cemented prosthesis is an abnormal pathologic condition which, if left unattended, will progress to a total failure of the joint including an inhibition of function and immobilizing pain. That biomaterial properties of the cement used for fixation also contribute to the pathologic

Cement distribution during post cementation
Journal of Dentistry, 1981Abstract The distribution of the cement around parallel-sided and tapered posts coated with cement, and when cement was inserted into the prepared post hole, have been compared. In every case coating the post with cement gave rise to an incomplete cement film. Rough-surfaced posts and tapered posts retained more cement than smooth parallel posts. The

Burns are a common condition presenting to the emergency department; the majority are thermal burns. The treatment for thermal burns and chemical burns differs greatly, and prompt recognition of a chemical burn is necessary. An often unrecognized and underestimated type of chemical burn is an alkali burn from wet cement.A 7-year-old boy was transferred

Microleakage of orthodontic band cement at the cement-enamel and cement-band interfaces
American Journal of Orthodontics and Dentofacial Orthopedics, 2010Our objective was to determine and compare microleakage patterns of conventional glass ionomer cement (GIC), resin modified GIC (RMGIC), and polyacid-modified composite for band cementation.Sixty freshly extracted third molars were randomly divided into 3 groups of 20 teeth each.

Portland cement carries a significant potential for morbidity if care is not exercised in its use. A 24-year-old construction worker suffered burns of both lower legs when wet cement seeped into his work boots causing burns and secondary cellulitis severe enough to preclude working for four weeks.

Cermet ionomer cements are sintered metal/glass powders, which can be made to react with poly(acids). These new cements are significantly more resistant to abrasion than regular glass ionomer cements and are widely accepted as core build-up materials and lining cements.

Expanding Cements for Primary Cementing
Journal of Petroleum Technology, 1966Abstract The expansion of cement and the effect of various expansive aids upon oil well cementing compositions have been investigated to determine the amount of expansion feasible and to observe the stability of cements displaying increased expansion.
