Effect of a common diet and regular beverage on enamel erosion in various temperatures: an in-vitro study.

Objective: This study compared diet and regular Coca-Cola on enamel erosion in cold and room temperatures.

Materials And Methods: Seventy five enamel specimens were prepared and divided into 5 equal groups (N=15) as follows: Group 1: regular beverage at room temperature, Group 2: regular beverage at refri-gerator temperature, Group 3: diet beverage at room and Group 4: diet beverage at refrige-rator temperature. The specimens were immersed in the regular or diet beverage (Coca-Cola, trade mark regd.

The Relationship between Salivary Beta-2 Microglobulin and Uremia Intensity in Men with Chronic Renal Failure.

Objective: This study defines the relationship between salivary beta-2 microglobulin (β2-M) and intensity of uremia in male patients diagnosed with chronic renal failure (CRF).

Materials And Methods: In total of 42 males were enrolled in a case-control study. There were 21 cases of CRF and 21 control cases.

Oral contraceptive use and salivary C-erbB-2, CEA and CA15-3 in healthy women: a case-control study.

Objectives: Oral contraceptives (OCP) are highly effective, safe and widely used. Higher exposure to endogenous and exogenous estrogens is generally thought to increase the risk of breast cancer. Therefore, this study was conducted to determine if oral contraceptive use affected the expression of CA 15-3, CEA and C-erb B-2 in the saliva of healthy women.

Serum Interleukin-6 as a Serologic Marker of Chronic Periapical Lesions: A Case-control Study.

Background And Aims: Chronic periapical disease with pulpal origin is an inflammatory condition caused by bacterial infection. Chronic infection could affect general health by increasing the production of cytokines such as interleukin-6 (IL-6) that probably play a role in pathogenesis of pulpal and periapical diseases. The aim of the present study was a comparative evaluation of the level of serum IL 6 in patients with periapical lesions and healthy controls.
