Context: The lack of a suitable armamentarium to aid in the disinfection and handling of gutta-percha (GP) cones during obturation has been a common challenge amongst dentists.
Aims: This study assessed the clinical usability of 'Vasundhara's (V) Transit GP' through a questionnaire-based survey.
Settings And Design: This questionnaire-based study was conducted in Davanagere, Karnataka, in February 2021 for 4 months.
Context: This is a novel preclinical endodontic model "Vasundhara's model for elementary endodontic training," featuring easy and convenient way for enhancing the skills of elementary endodontic procedures, simulating the clinical situation for endodontic teaching purposes. This article highlights the need, steps of fabrication of the model, and usage of the same for the universal benefit of the learners of endodontic techniques.
Aims: The aim is to describe the design and usage of a novel preclinical endodontic model which is simple, convenient, easy to fabricate, and cost-effective.
Background: Biosynthesized silver nanoparticles (AgNPs) have been proposed as effective antimicrobial agents against endo-perio pathogens. Determination of cytotoxicity is important for effective clinical use.
Aim: The aim is to determine the cytotoxicity of fungal-derived AgNPs on human gingival fibroblast (HGF) cell line using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.
Background: Endodontic-periodontal pathogens exist as biofilms which are difficult to eliminate. Biosynthesized silver nanoparticles (AgNPs) emerged as newer antimicrobial agents with potential benefits.
Aim: The aim of this study is to determine the minimum inhibitory concentration (MIC); evaluate the antibiofilm efficacy of fungal-derived AgNPs against , , and .
Aim: This study aims to evaluate the antibacterial efficacy of biosynthesized silver nanoparticles (AgNPs) produced using the fungi against biofilm model on root dentin.
Materials And Methods: AgNPs were biosynthesized using the fungi isolated from healthy leaves of . Minimum inhibitory concentration (MIC) of AgNPs was determined by microbroth dilution method using series of dilutions.
Background: The main objective of endodontic therapy is complete elimination and prevention of bacteria from the root canal system; however, it is difficult due to anatomical ramifications of root canal system and growing resistant microbes to available disinfectants. Therefore, to overcome this problem, newer antimicrobial agents have to be developed.
Aims: The aim of the study was to evaluate the antibacterial efficacy of fungal-derived biosynthesized silver nanoparticles (AgNPs) against .
Background: Even after rapid progress in contemporary dental practice, we encounter the failures due to endodontic, periodontal, or combined lesions. Complex anatomy of tooth and resistant microbes demands the development of new treatment strategies.
Aim: The aim of this study is to biosynthesize silver nanoparticles (AgNPs) using fungi and determine the antibacterial efficacy against , , and .
Introduction: Microbial resistance to existing antimicrobial agents in periodontal therapy is a growing problem. Therefore, there is a need for development of new antimicrobial agents.
Aim: To biosynthesize and characterize Silver Nanoparticles (AgNPs) using endophytic fungi and to evaluate the antibacterial efficacy against .
Aims: To assess the deproteinizing effect of bromelain enzyme and compare it with 5% sodium hypochlorite (NaOCl) on shear bond strength before application of the adhesive system.
Materials And Methods: A total of 30 extracted human premolars were divided into three groups, each one consisted of 10 teeth. The occlusal surface was wet ground to expose superficial dentin.
Background: Adhesive systems have enabled clinicians to preserve more tooth structure by changing cavity designs. However, because of the polymerization shrinkage adhesive systems are not capable of totally prohibiting the gap formation between the cavity and restorative material of composite resin leading to colonization of oral microorganisms from saliva. One possible solution for this serious problem is to use dental materials with antibacterial properties.

Materials And Methods: Sixty recently extracted human mandibular premolars were subjected for the study and divided into 4 groups of fifteen each. The adhesive materials Single Bond, Prime and Bond XP, Clearfil S3 Bond and G-Bond were applied to flat dentin surfaces according to the manufacturer's instructions.
Aim: Aim of this study was to compare class II composite restoration using flowable composites as lining with various thickness and curing techniques by evaluating cervical marginal microleakage.
Materials And Methods: Fifty intact molars, each prepared with two box-only class II cavities, were randomly divided into five groups: Group I, P60 filling alone; group II, ultrathin flowable composite lining (0.5-1mm) cocured with overlying composite; group III, thin lining (1-1.
This case report describes a technique used to treat smooth surface white spot lesions microinvasively. It is based on the infiltration of an initial enamel caries lesion with low-viscosity light-curing resins called infiltrants. The surface layer is eroded and desiccated, followed by resin infiltrant application.

Materials And Methods: A total of 90 single-rooted extracted human teeth were subjected for the study. Teeth were divided into 6 groups of 10 and 3 control groups of 10 teeth each.
Objective: To evaluate the apical sealing ability and adaptation of three resin-based sealers to the dentine.
Materials And Methods: A total of 66 recently extracted human maxillary anterior teeth were subjected for the study. The teeth were prepared and obturated with gutta-percha by a lateral condensation using AH Plus, Endorez and Epiphany sealers.
Objectives: The purpose of this study was to determine the microleakage in the 5(th) and 6(th) generation bonding agents with that compared with the newly introduced 7(th) generation bonding agents using three bonding agents.
Materials And Methods: A total of 50 recently extracted human upper premolars were subjected to the study. Class V cavity preparations were prepared on the buccal and lingual surfaces of the extracted premolars with occlusal margins in the enamel and gingival margins in the cementum/dentin.
Aim: This study was conducted to determine the effect of three cavity disinfectants (chlorhexidine gluconate based-Consepsis; benzalkonium chloride-based Tubulicid Red, iodine-potassium iodide/copper-sulphate based Ora-5) on the microleakage of a dentin bonding system, Clearfil SE Bond.
Materials And Methods: Class V cavities were prepared on 45 extracted molars. The respective experimentalgroups were treated with cavity disinfectants and Clearfil SE Bond.
