Effect of Heated Sodium Hypochlorite Irrigant on Structural Changes and Microhardness of Radicular Dentin: An Study.

Aim: This study is aimed to evaluate the combined effect of sodium hypochlorite at varied concentrations and temperatures on radicular dentin microhardness along with its surface structural changes using an FTIR spectrometer.

Materials And Methods: Mandibular premolars were cleaned and shaped up to F3 Protaper gold rotary files, after which they were subjected to five experimental conditions - group I - neutral saline as negative control, group II - 3% NaOCl solution, group III - 5% NaOCl solution, group IV - 3% intracanal-heated NaOCl solution, and group V - 5% intracanal-heated NaOCl solution. Following this, the microhardness of radicular dentin at 100 µm and 300 µm from the canal lumen and Fourier-transform infrared (FTIR) spectroscopic analysis were performed.

Objective: This study aimed to compare the two nickel-titanium (NiTi) instruments on root dentin thickness using cone-beam computed tomography (CBCT) and ability to remove the smear layer using scanning electron microscope (SEM).

Materials And Methods: The effect of two NiTi rotary instruments such as XP Endo shaper and ProTaper Gold (PTG) in retaining adequate dentin thickness and debridement (i.e.

Fracture resistance of resin based and lithium disilicate endocrowns. Which is better? - A systematic review of studies.

The primary objective of this systematic review is to compare the fracture resistance of lithium disilicate (LDS)-based endocrowns and resin-based (RB) endocrowns of in-vitro studies, and the secondary objective is to compare their catastrophic failures. The review protocol was registered in the P ROSP ERO database (CRD42020166201). A comprehensive literature search was done in PubMed, Cochrane, EBSCOhost and Google Scholar using key terms.

Comparative Evaluation of the Anti-bacterial Efficacy of Herbal Medicaments and Synthetic Medicaments Against Enterococcus faecalis using Real-time Polymerase Chain Reaction.

Periradicular bacterial infections are the proven cause of the failure of endodontic treatment. When the pulp canal gets infected or becomes necrotic, bacterial growth takes place in the form of biofilms and aggregates. During the endodontic procedure, bacterial colonies are disrupted, and the microbial load is reduced by biomechanical preparation, cleaning with anti-microbial solutions, and placing anti-bacterial medicaments in the root canal.

Evaluation of debris and smear layer removal with XP-endo finisher: A scanning electron microscopic study.

Context: The presence of smear layer and debris can prevent the irrigant and sealer from penetrating the dentinal tubules thereby compromising the seal of the root canal filling.

Aim: This study aims to evaluate the efficacy of XP-endo Finisher with ProTaper Next and HyFlex in smear layer and debris removal.

Materials And Methods: : Thirty-two extracted mandibular premolar teeth were selected and sectioned at the cementoenamel junction.

Evaluation of bioflavonoids on the immediate and delayed microtensile bond strength of self-etch and total-etch adhesive systems to sound dentin.

Aim: This study aims to evaluate the effect of two bioflavonoids (epigallocatechin-3-gallate [EGCG] and catechin) and a protein inhibitor (chlorhexidine [CHX]) on the immediate and delayed microtensile bond strength of self-etch and total-etch adhesive systems to sound dentin.

Materials And Methods: The occlusal surfaces of 96 mandibular human third molar teeth specimens were ground after removal of the excess tissues, to expose the middle dentin. The dentin specimens were randomly allocated into four groups, each consisting of 24 teeth (n = 24) according to the application of the enzyme inhibitor.
