Novel cryotherapy technique for pulpotomy in mature permanent teeth with symptomatic irreversible pulpitis- a randomized controlled trial.

Objectives: To assess the effect of cryotherapy on haemostasis, post-operative pain, and the outcome of full pulpotomy performed in mature permanent teeth with symptomatic irreversible pulpitis.

Materials And Methods: The study included sixty mature permanent mandibular molar teeth with symptomatic irreversible pulpitis and no periapical rarefaction. After coronal pulp tissue amputation, teeth were randomly allocated to one of two groups (n = 30 each).

Simple and Cost-Effective Quantum Dot Chemodosimeter for Visual Detection of Biothiols in Human Blood Serum.

An emission "turn-off" chemodosimeter for the naked-eye detection of biothiols using silica-overcoated cadmium selenide quantum dots is developed. Hole scavenging by the thiol group of cysteine, homocysteine, or glutathione on interaction with quantum dots resulted in an instant and permanent emission quenching under physiologically relevant conditions. Also, the emission suppression is so specific that thiols and substituted thiols (methionine and cystine) can easily be distinguished.

Quantum Dot-Based Fluorometric Sensor for Hg(II) in Water Customizable for Onsite Visual Detection.

An easy naked-eye detection technique for mercuric ions in water using silanized quantum dots is demonstrated. Cadmium selenide quantum dots were synthesized and rendered water soluble by silica overcoating. The quantum dot emission was instantly turned off by the mercuric ions in the analyte, enabling visual detection.

Influence of preoperative degree of tooth loosening and thickness of wire on the rigidity of wire composite splint.

Context: A wire composite splint (WCS) is most commonly used in clinical practice for the management of luxation dental injuries (LDIs). Wire thickness and adhesive point dimensions influence the rigidity of WCS. However, the influence of presplint tooth mobility on the rigidity of splint is not yet addressed.

Response to Pulp Sensibility Tests after Full Pulpotomy in Permanent Mandibular Teeth with Symptomatic Irreversible Pulpitis: A Retrospective Data Analysis.

Introduction: This retrospective study analyzed the 12-month pulp sensibility (cold and electric) test response after mineral trioxide aggregate (MTA) full pulpotomy in mature permanent teeth with symptomatic irreversible pulpitis.

Methods: The records of 120 subjects from 3 completed and 1 ongoing clinical study on MTA full pulpotomy were retrieved. Ninety-six first and second mandibular molar teeth with a diagnosis of symptomatic irreversible pulpitis that underwent a single-visit MTA full pulpotomy and had completed a 12-month clinical, radiographic, and pulp sensibility (cold and electric) test follow-up were included.

Influence of occlusal and proximal caries on the outcome of full pulpotomy in permanent mandibular molar teeth with partial irreversible pulpitis: A prospective study.

Aim: To assess the influence of occlusal and proximal deep carious lesions on the outcome of full pulpotomy performed in mandibular teeth with pulpal diagnosis of symptomatic partial irreversible pulpitis.

Methodology: Eighty deep carious mandibular molar teeth with clinical and radiographic diagnosis of symptomatic partial irreversible pulpitis without periapical rarefaction from patients of either gender between the age of 16-35 years were included. Depending upon the location of deep carious lesion, the teeth were distributed equally into occlusal (n = 40) and proximal caries groups (n = 40).

Green silver-nanoparticle-based dual sensor for toxic Hg(II) ions.

The present study focuses on the utilization of green silver nanoparticles, as they are preferred for sensing applications due to their environmentally friendly nature. We have examined the optical and electrochemical sensing behavior of silver nanoparticles from Agaricus bisporus (AgNP-AB) towards Hg(II) ions. The AgNP-AB was prepared by microwave reactor.
