Evaluation of new technique of sterilization using biological indicator.

Background: A novel technique of sterilization of endodontic files is introduced in this article.

Aims: Newly introduced sterilization unit, named "SteriFast" is compared with autoclave and glass bead sterilizer using biological indicator.

Materials And Methods: Spore strips of were cultured in nutrient broth.

Evaluation of effect of different disposable infection control barriers on light intensity of light-curing unit and microhardness of composite - An study.

Aims: This study evaluated effect of infection control barriers on light intensity (LI) of light-curing unit (LCU) and microhardness of composite.

Materials And Methods: Four different disposable barriers ( = 30) were tested against the control. LI for each barrier was measured with Lux meter.

Comparative evaluation of shaping ability of V-Taper 2H, ProTaper Next, and HyFlex CM in curved canals using cone-beam computed tomography: An Study.

Aim: The aim of this study was to compare the canal transportation and canal centering ability in the preparation of curved root canals after instrumentation with V-Taper 2H, ProTaper Next (PN), and Hyflex CM files using cone-beam computed tomography (CBCT).

Materials And Methods: Thirty mesiobuccal canals of mandibular molars with an angle of curvature ranging from 20 to 40 were divided according to the instrument used in canal preparation into three groups of ten samples each: V-Taper 2H (Group 1), PN (Group 2), and Hyflex CM (Group 3). The teeth were instrumented according to manufacturer's guidelines up to 30 no.

In vitro evaluation of the antimicrobial efficacy of chitosan and other endodontic irrigants against Enterococcus faecalis.

The success of endodontic treatment is directly enhanced by elimination of microorganisms in infected root canals. Recently, chitosan, a natural, nontoxic biopolymer, has been introduced as an irrigant that has the capacity to remove the smear layer. The antimicrobial properties of chitosan as an endodontic irrigant have not yet been explored.

Evaluation of effect of ultrasonic scaling on surface roughness of four different tooth-colored class V restorations: An in-vitro study.

Aims: This study evaluated the effect of ultrasonic scaling on surface roughness of four different tooth-colored class V restorations.

Materials And Methods: Out of 100 human extracted teeth, 20 were randomly selected for each group, marked with the outline of class V cavity. Class V cavities were prepared on facial surface of teeth of all groups except control group.

Evaluation of softening ability of Xylene & Endosolv-R on three different epoxy resin based sealers within 1 to 2 minutes - an in vitro study.

Objectives: This study evaluated the efficacy of Endosolv-R and Xylene in softening epoxy resin based sealer after 1 to 2 min exposure.

Materials And Methods: Sixty Teflon molds (6 mm × 1.5 mm in inner diameter and depth) were equally divided into 3 groups of 20 each.
