Blockchain technology and the metaverse have the potential to revolutionize dentistry and healthcare by enhancing data security, patient empowerment, disaster victim identification, and the delivery of dental services. In this review, we discuss the current state of the art in the field of dentistry and the future of dentistry, highlighting the advantages and challenges of utilizing blockchain technology for disaster victims’ identification. Blockchain's applications in Disaster Victim Identification (DVI) offer a humanitarian dimension, helping bring solace to families in times of tragedy. Moreover, blockchain's potential to establish virtual health clinics and telemedicine platforms could bridge healthcare gaps in underserved regions.

Oral cancer detection at an early stage remains a challenging situation for health professionals in the rural setup. This is due to lack of training and infrastructure facilities. In the era of modernization, when tools like artificial intelligence and machine learning are gaining acceptance, this article throws insight into the role of AI as a tool for improving oral cancer outcomes.

Dental implants are the most innovative strategy for substituting a missing tooth. Smoking has been identified as a significant risk factor impacting the success rates of dental implants. This study explores the correlation between tobacco use and implant failure focusing on the physiological mechanisms involved. Smoking impairs osseointegration, the critical process where the implant integrates with the alveolar bone due to reduced blood flow oxygenation and angiogenesis caused by nicotine and carbon monoxide. Smokers exhibit higher rates of implant failure compared to non-smokers with compromised bone quality and delayed wound healing as contributing factors. Studies suggest that smoking adversely affects implant stability, particularly during the critical early healing phase. This review highlights the biological mechanisms and clinical implications of smoking on dental implant outcomes.

Autism is a developmental disorder mostly affecting neural and developmental skills with problems in learning, communication and repetitive behaviour. It has become more highlighted over the past few decades because of the increasing awareness, survey tools and research worldwide. Existing worldwide, this disorder affects the normal lifestyle of the affected people since childhood and continues with the same pace through lifetime. Due to poor neuromuscular coordination, it also affects the normal orofacial dynamics of an individual and manifests as multiple oral disorders. Therefore it's of interest to report known data on the oral manifestations of this spectral disorder and various approaches at varied levels to maintain a harmonious oral environment.

Integration of metaverse technology in dentistry is transforming patient treatment, education and professional growth. This investigation examines the awareness, attitude and preparation of dental students and practitioners regarding metaverse applications in their field of work. Hence, 476 participants were asked about their awareness of artificial intelligence, XR, block-chain and digital twins, together with the various advantages and disadvantages of these technologies. While metaverse adoption is widely sought, especially in education and training, questions about cost, privacy and usability still linger. Thus, the need for structured learning programs to maximize the benefits of metaverse technology and raise dental practitioners' digital proficiency is highlighted.

The correlation between remaining dentin thickness and fracture resistance in prepared teeth is of interest to dentists. A sample of 60 human teeth (mandibular premolars) was extracted and examined using cone beam computed tomography to assess residual dentin thickness before and after instrumentation. The gathered samples have been divided into three distinct categories, each with 20 samples. Hand files were used in Group 1, Protaper Next was used in Group 2, and a V taper was used in Group 3. They were examined for remaining dentin thickness after preparation with 3D CS Software and fracture resistance utilizing a Universal Testing Machine (UTM). Therefore, the objective of this research is to compare the amount of dentin removed by V Taper and Pro Taper Next to hand files using CBCT at the apical and coronal middle levels. Following that, these values will be correlated with fracture resistance values obtained from the Universal Testing Machine.
