A bio-inspired adjustable posture quadruped robot with laterally undulating spine for terradynamically challenging environments.

Morphological adaptation is vital for biological organisms navigating changing environments. While robots have sought to emulate this adaptability with adjustable body structures, practical robotic applications remain constrained by the complexity of integrating advanced materials, sophisticated control systems, and novel design approaches. This paper introduces a bioinspired quadruped robot featuring both a laterally undulating spine and posture-changing mechanism, specifically designed for adaptation in complex terradynamic environments.

Comparison of Two Reciprocating File Systems with Continuous Rotation System in Root Canal Preparation: A Randomized Clinical Control Trial.

Background: This study aimed to compare the degree of postoperative pain and analgesic consumption after the root canal procedure of mandibular premolar by utilizing two reciprocating and a continuous rotary file system and also evaluate the long-term periradicular status by periapical index (PAI) scores.

Materials And Methods: There were 84 patients, aged 18-55 years with mandibular premolar teeth recommended for root canal treatment who were treated under a predetermined protocol. Based on the instrumentation system used, all the patients were allocated randomly into three groups ( = 28): Group I: Reciprocating file no 1-ONE RECI, group II: Reciprocating file no 2-E3 AZURE, and Group III: Continuous rotary file-HERO GOLD, respectively.

Nanobots: An endodontist saviour.

The application of nanoparticles in the form of solution for irrigation, medication and as an additive for sealer/restorative material has been evaluated to improve the antibacterial efficacy in the field of endodontics. Recently developed nanobots are injected into the teeth to destroy pathogens and they are more effective in root canal therapy. They are helical shaped and composed of silicon dioxide with iron embedded into the silica body to provide magnetic properties.

Comparative Evaluation of Sealing Ability of Different Type of MTA as Root-End Filling Materials Using Dye Penetration Technique - An Study.

Introduction: The main goal of the root-end filling material is to create a hermetic seal to protect against microbes and their by-products. Excellent biocompatibility and sealing ability are characteristics of MTA developed by Torabinejad . This study aimed to compare the sealing ability of different type MTA as root-end filling material using dye penetration technique.

Antibacterial Efficacy of Mineral Trioxide Aggregate, Bioactive Glass and Epoxy-Resin Based Sealer: An Interventional Study.

Aim: The aim and objective of this study was to evaluate the antibacterial efficacy of mineral trioxide aggregate, bioactive glass sealer, and epoxy-resin-based sealer.

Materials And Methods: In the present study, 22 Mueller Hinton agar (MH agar) plates were employed and equally divided into two groups. Three holes were made by removal of agar at equidistant points and filled with root canal sealers.

Comparison of Antibacterial Activity of Various Additives to Glass Ionomer Restoration: An Study.

Introduction: Glass-ionomer (GIC) cement was introduced in 1972 as a "new filling material of dentistry". It is bioactive and plays an important role in caries prevention due to its ability to release fluoride into the oral environment and remineralization of dental hard tissues. However, its properties such as moisture sensitivity, wear resistance, and bond strength are not sufficient to inflict the antimicrobial environment.

Morphological Variation of Mandibular Molars in Rohilkhand Population: An Original Research.

Introduction: In-depth knowledge of common and aberrant pulp morphology is essential for appropriate diagnosis and treatment planning before commencing root canal treatment. The radicular morphology of mandibular molars has been extensively studied. Considerable variation in the number of canals and roots found in these teeth has been reported.
