Comparative Evaluation of the Accuracy of Electronic Apex Locator and Digital Radiography for Working Length Determination in Primary Teeth: A Systematic Review.

Statement Of The Problem: It is challenging to perform a pulpectomy procedure in primary tooth because of its physiological root resorption and variation in root morphology. Working length measurement is considered to be one of the critical steps, as it determines the extent of obturation and apical seal.

Purpose: To compare the accuracy of electronic apex locator (EAL) and digital radiography (DR) for working length determination in primary teeth.

Shape Sensing of Cantilever Column Using Hybrid Frenet-Serret Homogeneous Transformation Matrix Method.

The Frenet-Serret (FS) framework stands as a pivotal tool in shape sensing for various infrastructures. However, this tool suffers from accumulative errors, particularly at inflection points where the normal vector undergoes sign changes. To minimize the error, the traditional FS framework is modified by incorporating the homogeneous matrix transformation (HMT) method for segments containing inflection points.

Correlation of Ora Test and Caries Assessment Spectrum and Treatment Index (CAST) to Evaluate Caries Activity in 5-to-8-Year-Old Children.

Dental caries is a common chronic disease amongst children and are typically evaluated using the DMFT/deft index (decayed, missing, and filled teeth for permanent dentition/decayed, extracted, and filled teeth for primary dentition). To address the limitations associated with these indices, alternative assessment tools such as the Caries Assessment Spectrum and Treatment (CAST) index and Ora test have been developed. These methods aim to estimate caries activity within the oral cavity more accurately.

Comparison of pain perception between computer-controlled local anesthetic delivery and the conventional syringe for inferior alveolar nerve block in children.

Background: Local anesthesia (LA) is commonly used for pain control in clinical dental practice. However, it is often perceived as the most painful part of the treatment and the factor leading to the avoidance of dental care. Hence, research on better means of pain management is being conducted.

Nanotechnology: Newer Approach in Insulin Therapy.

Insulin is a peptide hormone released by pancreatic beta cells. An autoimmune reaction in diabetes mellitus type 1 causes the beta cells to die, preventing insulin from being produced or released into the bloodstream; that impacts 30 million people globally and is linked to shortened lifespan due to acute and chronic repercussions. Insulin therapy aims to replicate normal pancreatic insulin secretion, which includes low levels of insulin that are always present to support basic metabolism, as well as the two-phase secretion of additional insulin in response to high blood sugar - an initial spike in secreted insulin, followed by an extended period of continued insulin secretion.

The second objective was to correlate it with demographic characteristics and evaluate the need for oral health education programs for teachers.

Teledentistry: A Boon Amidst COVID-19 Lockdown-A Narrative Review.

The recent spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its associated coronavirus disease (COVID-19) has caused widespread public health concerns. Despite huge efforts to contain the disease spread, it is still on the rise because of the community spread pattern of this infection. In order to prevent the community spread, a nationwide lockdown was implemented, due to which many restrictions were imposed on movements of citizens within the country.

Effectiveness of Virtual Reality Eyeglasses as a Distraction Aid to Reduce Anxiety among 6-10-year-old Children Undergoing Dental Extraction Procedure.

Introduction: Distraction is commonly used nonpharmacologic pain management technique by pedodontists to manage pain and anxiety. There are some new techniques which uses audiovideo stimulation and distract the patient by exposing him or her to three-dimensional videos. These techniques are referred to as virtual reality audiovisual systems.

Validation of "left ventricular early inflow-outflow index": A novel echocardiographic method for quantification of mitral regurgitation in an Indian population with special focus on rheumatic etiology.

Background: Quantification of mitral regurgitation (MR) has always required an "integrated approach" as there is no single gold-standard method. We investigated a new Doppler-derived parameter "left ventricular early inflow-outflow index (LVEIO)" for the quantification of MR and its likelihood to predict severe MR in correlation with already established parameters in an Indian population including a large subset of patients with rheumatic etiology.

Methods: A prospective study was performed at a major tertiary care center in western India over a 5-month period.

Study of Impact Damage in PVA-ECC Beam under Low-Velocity Impact Loading Using Piezoceramic Transducers and PVDF Thin-Film Transducers.

Compared to conventional concrete, polyvinyl alcohol fiber reinforced engineering cementitious composite (PVA-ECC) offers high-strength, ductility, formability, and excellent fatigue resistance. However, impact-induced structural damage is a major concern and has not been previously characterized in PVA-ECC structures. We investigate the damage of PVA-ECC beams under low-velocity impact loading.

Appropriateness of elective percutaneous coronary intervention and impact of government health insurance scheme - A tertiary centre experience from Western India.

Background: There is a dearth of data regarding the appropriateness of elective percutaneous coronary intervention (PCI) in a limited-resource country such as India. In an attempt to rationalise the use of PCI, Appropriate Use Criteria (AUC) were developed for cardiovascular care in the USA. In the Indian context, considering the high prevalence of coronary artery disease, the dramatic rise in the number of revascularization procedures and an increasing role of government/private reimbursements, application of AUC could potentially guide policy to optimize the utilization of resources and the benefit-risk ratio for individual patients.
