The use of a cotton pellet as a spacer or as a medication carrier in the tooth pulp chamber between root canal therapy appointments is an accepted and common practice. Retaining the pellet in the proper position within the tooth is very important. Cellulose fibers from disposable drapes, gowns and cotton can cause foreign body reactions if left in a surgical wound." In addition, cellulose fiber...

OBJECTIVES This study aimed to compare the surface microhardness of mineral trioxide aggregate (MTA) samples having different thicknesses and exposed to human blood from one side and with or without a moist cotton pellet on the other side. MATERIALS AND METHODS Ninety cylindrical molds with three heights of 2, 4, and 6 mm were fabricated. In group 1 (dry condition), molds with heights of 2, 4...

Objectives-To evaluate anti-inflammatory activity of rosiglitazone in the acute and chronic models of inflammation. Also to determine ulcerogenic potential on gastric mucosa in Wistar rats in comparison with diclofenac. Methodology-Anti-inflammatory effects of rosiglitazone in the dose of 1, 3 and 10 mg/kg b.wt., i.p were studied in acetic acid-induced peritoneal capillary permeability model in...

This study evaluated the influence of the exposure of mineral trioxide aggregate (MTA) - with and without calcium chloride (CaCl2) -to phosphate-buffered saline (PBS) on apical microleakage. Sixty root segments were divided into 4 experimental groups (n=15). Apical cavities were filled with MTA with or without CaCl2, and the root canals dressed with a moistened cotton pellet or PBS: 1) MTA/cott...

OBJECTIVE The aim of this study was to evaluate the influence of exposure of the mineral trioxide aggregate (MTA) - with and without calcium chloride (CaCl2) - to phosphate-buffered saline (PBS) on the apical microleakage using a glucose leakage system. MATERIAL AND METHODS Sixty root segments were randomly divided into 4 experimental groups (n=15). After resecting the apical segments and enl...

PURPOSE This investigation evaluated the success of a formocresol pulpotomy technique in which hemostasis was obtained with the same formocresol dampened cotton pellet used to medicate the root pulp stumps and to compare the findings of this investigation with data of published formocresol pulpotomy studies in which hemorrhage was controlled by traditional means. METHODS Clinical and radiogra...

the ethanolic extract of wedelia chinensis (eewc) belonging to the family of asteraceae was evaluated by hot plate and acetic acid induced writhing methods to assess its analgesic activity. the extract was also evaluated for its by using on carrageenan, mediators such as histamine and serotonin induced paw oedema, and cotton pellet induced granuloma tests for its effect on acute and chronic pha...

The anti-inflammatory effect of selagin-7-O-(6″-O-Acetyl-)-β-D-glucoside, isolated from the medicinal herb Cancrinia discoidea (Ledeb.) Poljak, was evaluated for its anti-inflammatory activity in the carrageenin- and serotonin-induced rat paw oedema models of acute inflammation and the cotton pellet-induced granuloma rat model of chronic inflammation. Flavone glycoside at doses of 5, 10, or 20 ...

Aim: To investigate the analgesic and anti-inflammatory properties of seed extracts of Diplocyclos palmatus (L) C. Jeffrey. Methods: Three extracts of different polarity of Diplocyclos palmatus (L) C. Jeffrey seeds were tested for their analgesic and anti-inflammatory activities. Analgesic activity was evaluated using the hot plate and acetic acid-induced writhing in mice. Antiinflammatory acti...
