Objective: The aim was to evaluate the effect of root canal geometry on amount apical extrusion irrigant, by testing different tapers and needle types. Materials Method: Forty-three extracted single-rooted human mandibular premolar teeth were accessed. Experimental groups instrumented produce increasing amounts taper in each successive group: Group 1 (#25/.02), 2 (#25/.04), 3 (#25/.06), 4 (#25/...

Bacterial reinfection and root fracture are the main culprits related to canal treatment failure. This study aimed assess utility of quercetin solution as an adjunctive endodontic irrigant that does not weaken dentin with commitment anti-biofilm activity bio-safety. Based on a noninvasive infection model, tubules infected Enterococcus faecalis (E. faecalis) were irrigated sterile water (control...

BACKGROUND Saline irrigations are proving to be a valuable intervention in the treatment of chronic sinusitis. The use of surfactants is a well established additive to topical treatments known to reduce surface tension and may prove to be a simple, nonoperative intervention to improve intrasinus douching penetration. METHODS Six 30-mL, flat-bottomed medicine cups with circular holes cut thro...

Aim Compare efficacy of Dual Rinse HEDP with sodium hypochlorite to in combination a finishing rinse 17% EDTA solution remove the smear layer. Materials and methods Sixteen human maxillary single-rooted, single canalled sound premolars were used. Specimens distributed into 2 groups labeled according irrigation protocol Each group consisted 8 specimens: Group 1 50% NaOCl followed by EDTA. The Ri...

Objective: To evaluate the cytotoxicity and antibacterial effect of bleached turmeric hydro-alcoholic extractcompared to sodium hypochlorite as an endodontic irrigant. Material Methods: Cytotoxicity was evaluatedon human skin fibroblasts using MTT assay. The irrigants were tested at 1, 5- 15-minutes time intervals. Aftercontact time, solution added well plates incubated. After incubation period...

INTRODUCTION Heating a sodium hypochlorite solution improves its effectiveness. The aim of this study was to measure the in vivo temperature changes of sodium hypochlorite solutions that were initially preheated to 66°C or at room temperature inside root canals during routine irrigation. METHODS Thirty-five root canals were prepared to ISO size 40 with 4% taper. A type K (nickel-chromium-nick...

The main objective of endodontic treatment is the total removal any necrotic tissues and microorganisms along with their byproducts found within infected root canal to treat prevent recolonization these micrbad oorganisms. To date, no known irrigant has a 100% elimination rate on microorganisms, many combinations irrigates have been suggested, care must be taken mixing interaction side effects....

UNLABELLED Ideally root canal irrigants should have, amongst other properties, antimicrobial action associated with a lack of toxicity against periapical tissues. Sodium hypochlorite (NaOCl) is a widely used root canal irrigant, however it has been shown to have a cytotoxic effect on vital tissue and therefore it is prudent to investigate alternative irrigants. Sterilox's Aquatine Alpha Electro...
