Estimation of MBC: MIC Ratio of Herbal Extracts against Common Endodontic Pathogens.

Herbal extracts have evoked interest owing to the small number of terpenoids and phenolic compounds, which impart antimicrobial, antioxidant, and anti-inflammatory properties. The minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and minimum fungicidal concentration (MFC) of four herbal extracts (lemon grass oil, basil oil, peppermint oil, and Obicure tea extract) against endodontic pathogens along with the MIC: MBC/MFC ratio were evaluated. The antimicrobial activity by detecting the MIC of three essential oils and tea extract was evaluated against eight common endodontic pathogens by the broth dilution method, while MBC was detected by subculturing onto blood agar from the first -three to five tubes from the MIC dilution tubes (showing no turbidity), which were plated on blood agar.

A Comparative Study of Practice, Perception, and Attitude of Undergraduate Healthcare Students towards Toothbrush Selection, Maintenance and Replacement in RAS Al-Khaimah, United Arab Emirates.

Aim: Oral hygiene is one of the most significant lifestyle-related determinants of well-being. Health sciences undergraduate students are not only future healthcare providers but also educators of society in maintaining the overall general health. The aim of the study was to assess the practice, perception, and attitude of healthcare students in RAS Al-Khaimah toward toothbrush selection, maintenance, and replacement.

Graphene nanoplatelets embedded polymer: An efficient endodontic material for root canal therapy.

The design and preparation of clinically relevant endodontic obturating material for root canal therapy is a great challenge. For the first time, we report a new polymer nanocomposite which was prepared by using reversible addition-fragmentation chain-transfer (RAFT) polymerization of methacrylic acid and methylene glycol dimethacrylate. The polymer was embedded with reduced graphene oxide nanoplatelets (rGO).

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.

Evaluation of antimicrobial activity and efficacy of herbal oils and extracts in disinfection of gutta percha cones before obturation.

Objectives: Literature has shown that micro-organisms contaminate gutta percha (GP) during storage and manipulation. Till date herbal extracts are not explored as an alternative medicament for pre-operative chairside disinfection of GP cones. The purpose of our study was to evaluate the antimicrobial activity and efficacy of lemon grass oil (LG), basil oil (BO), and obicure tea extract (OT) in disinfecting GP cones before obturation.

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.

Comparison of acceptance, preference and efficacy between pressure anesthesia and classical needle infiltration anesthesia for dental restorative procedures in adult patients.

Introduction: Intraoral local anesthesia is essential for delivering dental care. Needless devices have been developed to provide anesthesia without injections. Little controlled research is available on its use in dental restorative procedures in adult patients.

A comparative evaluation of fracture resistance of endodontically treated teeth restored with different post core systems - an in-vitro study.

Purpose: To compare the fracture resistance and the mode of failure of endodontically treated teeth restored with different post-core systems.

Materials And Methods: Root canal treatment was performed on 40 maxillary incisors and the samples were divided into four groups of 10 each. For three experimental groups post space preparation was done and teeth were restored with cast post-core (Group B), stainless steel post with composite core (Group C) and glass fiber post with composite core using adhesive resin cement (Group D).
