The pulpal pathways in primary teeth differ significantly from permanent teeth due to their larger pulp chambers, thinner dentin walls, and increased susceptibility to caries and trauma. The root canals are often irregular, with multiple accessory canals and natural resorptive changes as the tooth approaches exfoliation. These anatomical variations make endodontic treatment more challenging, requiring careful access opening and minimal removal of tooth structure. The complex morphology, along with a higher risk of perforation and incomplete debridement, necessitates a thorough understanding of the pulpal anatomy. Proper treatment planning ensures the preservation of primary teeth until their natural exfoliation, supporting the healthy eruption of permanent successors.

A dental operating microscope (DOM) is an advanced magnification tool designed to enhance precision, visualization, and ergonomics in dental procedures. It provides high-quality magnification and illumination, enabling dentists to see fine details that are difficult to detect with the naked eye or traditional loupes. This improves accuracy in treatments such as root canal therapy, restorative dentistry, and microsurgery. By enhancing visibility and reducing strain, the DOM helps ensure better treatment outcomes, increased efficiency, and improved patient care.

Reconfigurable intelligent surface (RIS) has emerged as a cutting-edge technology for beyond 5G and 6G networks due to its low-cost hardware production, nearly passive nature, easy deployment, communication without new waves, and energy-saving benefits. Unmanned aerial vehicle (UAV)-assisted wireless networks significantly enhance network coverage. Resource allocation and real-time decision-making optimisation play a pivotal role in approaching the optimal performance in UAV- and RIS-aided wireless communications. But the existing contributions typically assume having a static environment and often ignore the stringent flight time constraints in real-life applications. It is crucial to improve the decision-making time for meeting the stringent requirements of UAV-assisted wireless networks. Deep reinforcement learning (DRL), which is a combination of reinforcement learning and neural networks, is used to maximise network performance, reduce power consumption, and improve the processing time for real-time applications. DRL algorithms can help UAVs and RIS work fully autonomously, reduce energy consumption and operate optimally in an unexpected environment. This co-authored book explores the many challenges arising from real-time and autonomous decision-making for 6G. The goal is to provide readers with comprehensive insights into the models and techniques of deep reinforcement learning and its applications in 6G networks and internet-of-things with the support of UAVs and RIS. Deep Reinforcement Learning for Reconfigurable Intelligent Surfaces and UAV Empowered Smart 6G Communications is aimed at a wide audience of researchers, practitioners, scientists, professors and advanced students in engineering, computer science, information technology, and communication engineering, and networking and ubiquitous computing professionals.

Anesth sie locale en odontologie p diatrique enseigne au clinicien comment administrer une injection d'anesth sie locale efficace et s re un enfant ou un adolescent. Plut t que d' viter l'administration locale par crainte de traumatiser le patient p diatrique, le clinicien devrait s'efforcer d'apprendre et d'utiliser les derni res modalit s de contr le de la douleur locale afin d' viter une exp rience dentaire d sagr able et inconfortable pour l'enfant et d'en faire une exp rience joyeuse et fructueuse.

Lokalan sthesie in der Kinderzahnheilkunde lehrt den Kliniker, wie er einem Kind oder Jugendlichen eine wirksame und sichere Lokalan sthesie-Injektion verabreichen kann. Anstatt die rtliche Bet ubung aus Angst vor einer Traumatisierung des p diatrischen Patienten zu vermeiden, sollte sich der Arzt bem hen, die neuesten Modalit ten der lokalen Schmerzkontrolle zu erlernen und anzuwenden, um unangenehme und unkomfortable zahn rztliche Erfahrungen f r das Kind zu vermeiden und sie zu einer fr hlichen und fruchtbaren Erfahrung zu machen.

Anestesia locale in odontoiatria pediatrica insegna al medico come somministrare un'iniezione di anestesia locale efficace e sicura a un bambino o a un adolescente. Piuttosto che evitare la somministrazione locale per paura di traumatizzare il paziente pediatrico, il medico dovrebbe sforzarsi di apprendere e utilizzare le pi recenti modalit di controllo locale del dolore per evitare al bambino un'esperienza odontoiatrica spiacevole e disagevole e renderla invece allegra e fruttuosa.

Anestesia local em Odontopediatria ensina o cl nico a administrar uma inje o de anestesia local eficaz e segura a uma crian a ou adolescente. Em vez de evitar a administra o local por receio de traumatizar o doente pedi trico, o cl nico deve esfor ar-se por aprender e utilizar as modalidades mais recentes de controlo da dor local para evitar uma experi ncia dent ria desagrad vel e desconfort vel para a crian a e torn -la alegre e proveitosa.

Local Anaesthesia in Pediatric Dentistry teaches the clinician how to administer an effective and safe local anaesthesia injection to a child or and adolescent. Rather than avoiding local administration for fear of traumatizing the pediatric patient, the clinician should strive to learn and use the latest modalities of local pain control to avoid unpleasant and uncomfortable dental experience for the child and making it a cheerful and fruitful one.
