This case report presents a maxillary third molar with a C-shaped canal system. This is the first known description of a maxillary third molar with C-shaped anatomy. This unique pulp chamber morphology was observed under the operating microscope. Root canal treatment consisted of cleaning and shaping combined with ultrasonic irrigation with sodium hypochlorite. A calcium hydroxide dressing was ...

: Calcium hydroxide (Ca(OH)2) has been used as a root canal medicament due to its antimicrobial activity and organic tissue dissolution capacity. To, increase the efficiency success of canal/endodontics treatment calcium be removed from canals walls. This study evaluate compare four different irrigation system i.e. Conventional Irrigation (plastic 30 gauge needle), Sonic ( Endoactivator), Ultra...

To evaluate disinfection methods for environments contaminated with bioterrorism-associated microorganism (Bacillus anthracis), we performed the following experiments. First, the sporicidal effects of sodium hypochlorite on spores of five bacterial species were evaluated. Bacillus atrophaeus was the most resistant to hypochlorite, followed in order by B. anthracis, Clostridium botulinum and Clo...

AIM To evaluate and compare ex vivo the decalcifying effect of 15% EDTA, 15% citric acid, 5% phosphoric acid and 2.5% sodium hypochlorite on root canal dentine. METHODOLOGY Two 2-mm-thick slices were cut from the coronal third of the root of 10 human incisors. Each slice was sectioned into two equal parts. Specimens were assigned to one of four groups (n = 10) for immersion in 20 mL of either...

Background. The aim of the present study was to evaluate the effect of Corega and 2.5% sodium hypochlorite cleansing agents on the shear and tensile bond strengths of GC soft liner to denture base. Methods. A total of 144 samples (72 samples for tensile and 72 for shear bond strength evaluations) were prepared. The samples in each group were subdivided into three subgroups in terms of the clean...

The article presents the results of research on influence enzymatic and oxidizing agents polymers used in drilling mud technology. calcium hypochlorite, urea peroxide, sodium persulfate, amylase cellulase. This allowed us to determine optimal concentrations these order reduce rheological parameters muds. ability enzymes oxidants decompose colloids composition muds was determined basis measureme...

Background. This in vitro study aimed to compare the antibacterial effect of different concentrations of sodium hypochlorite on elimination of Enterococcus faecalis from root canal systems of primary teeth with or without a passive sonic irrigation system (EndoActivator). Methods. The root canals of 120 extracted single-rooted primary incisors were prepared using the crown-down technique. The t...

Calcium is an essential nutrient the human body needs to control blood pressure and maintain strong bones teeth. One type of calcium that often consumed safe for health carbonate. It can obtain this material from chicken eggshell waste, where it known CaCO3 content 95%. Therefore, conducted research see phase, functional group, absorbance level, energy band gap samples. was synthesized using ca...

introduction: antimicrobial activity of interappointment intracanal medications is an important consideration in endodontics. considering the fact that calcium hydroxide (ch) cannot sterilize the root canal system, completing its antimicrobial spectrum seems necessary. the aim of this study was to compare the antibacterial activity of ch combined with three different vehicles in root canal syst...
