Effects of online marketplace-sourced over-the-counter tooth whitening products on the colour, microhardness, and surface topography of enamel: an in vitro study.

Objectives: This study compared the whitening effect, microhardness, and enamel surface alterations of over-the-counter (OTC) tooth bleaching products with those of a dentist-prescribed at-home bleaching agent.

Materials And Methods: The products available on a popular online marketplace were comprehensively searched and then rated using a specific formula. The effects of the lowest-rated OTC agent (LRA) and the highest-rated OTC agent (HRA) were compared with those of a dentist-prescribed bleaching agent (DPA) on the enamel of extracted human teeth.

Sodium Hypochlorite Concentration and Postendodontic Pain - Unveiling the Optimal Balance: A Systematic Review and Meta-Analysis.

Introduction: This study systematically reviewed literature regarding the effect of different concentrations of sodium hypochlorite (NaOCl) used during root canal treatment (RCT) on postendodontic pain (PEP) and rescue analgesia.

Methods: Following registration with PROSPERO (CRD42023388916), a search was conducted using PubMed, Scopus, Web of Science, and Embase databases. Randomized controlled trials of patients receiving RCT which assessed PEP at different time intervals were included.

Teleradiology and the Compensation Conundrum in India.

Teleradiology, an established telemedicine practice globally, has significantly enhanced the accessibility of high-quality radiological interpretations in remote areas worldwide, especially in India, thereby improving healthcare outcomes. The utilization of teleradiology services has seen a marked increase, expanding its reach into more distant regions of the country. However, this burgeoning field faces numerous regulatory, financial, and technical challenges.

Effects of traditional and novel proteolytic agents on tissue dissolution and dentine microhardness.

The study aimed to evaluate the tissue-dissolving ability of papain and bromelain with respect to that of sodium hypochlorite (NaOCl) at the temperatures of 25°C and 60°C. The study also assessed the effects of these proteolytic agents on radicular dentine microhardness. Warming NaOCl, papain and bromelain solutions resulted in significant tissue dissolution at all time intervals (p < 0.

Post-traumatic hollow viscus perforation with mesenteric and bowel ischemia.

Hollow viscus perforation and acute mesenteric ischemia are life-threatening conditions that must be recognized and managed appropriately. Computed tomography (CT) helps to visualize the bowel wall directly, as well as in the timely diagnosis of secondary signs of bowel ischemia. The radiologist should be familiar with the signs of pneumoperitoneum on supine radiographs for detection of hollow viscus perforation.

Comparison of Tracheal Diameter Measurements on Radiograph Versus Computed Tomography at a Tertiary Care Hospital in Pune, Central India.

Background Variations in tracheal diameter with respect to factors like age and gender are one of the major factors affecting the size of the endotracheal tube (ETT) preferred in a patient. It is important to pre-determine this figure because a tube of a larger size predisposes the patient for tracheal mucosal ischemia, while one of a smaller size may not ensure adequate oxygen saturation in the patient. Purpose We undertook this study to assess the accuracy of radiograph versus computed tomography (CT) and comment on whether a CT should be carried out mandatorily in all patients where intubation is needed.
