Canine impaction is a condition wherein the tooth is embedded in the alveolus and is locked in by bone, teeth, or other structures, leading to difficulty in eruption. In this study, we present a case report of a 15-year-old female patient with a straight profile, class I skeletal and dental relationship, over retained deciduous teeth, severe anterior crowding in both the arches, and impacted canine in maxillary arch on both the sides and in mandibular arch on the right side. Extraction of deciduous teeth was done prior to fixed appliance therapy. After leveling and alignment using fixed appliance, surgical exposure of impacted canines was done using open flap surgical technique. Canines were brought into occlusion using conventional orthodontic technique. In mandibular arch, space for lingually placed lateral incisor was created using nickel-titanium (NiTi) open coil spring. Results achieved after decrowding and getting impacted canines into normal occlusion are presented.
Introduction: Interproximal enamel reduction dates back to 1944 when it was first advocated for correcting lack of tooth size harmony by stripping the proximal surfaces of the mandibular anterior segment. Despite convincing results, interproximal reduction (IPR) only became popular after the advent of bonding, as full-arch banding done previously completely deferred the use of this method for tooth material reduction. With the current status and ongoing development of new techniques of IPR, use of this method as a mean of gaining space has increased exponentially over the last three decades.Procedure: A 12-inch length of 0.036" diameter wire is used for fabrication of the assembly. Helices of 2.5 mm diameter with two coils and the other according to finger grip are fabricated, and U-loops are prepared at the free ends for engaging the proximal strips. This assembly can be placed intraorally in the interdental region of our choice to cut the tooth material. Conclusion:This assembly provides an effective grip rather than using hand held strips. It is also accessible in both anterior and posterior regions with a minimum requirement of armamentarium and can be sterilized and reused.
Aim To explore a successful, much simpler, less cumbersome, and time-consuming technique for mini-implant placement. Materials and Methods Crimpable hook, intraoral periapical radiograph, 15 number surgical blade. Results Very simple and efficient technique for mini-implant placement. Conclusion The proximity of roots in mandibular arch is major risk factor for placements of mini-implants. With the help of this technique, the proper direction and orientation of the miniimplant to be placed can be evaluated. Clinical significance There is no additional armamentarium required for this technique with the least clinical time for the operator providing a very efficient way for mini-implant placement.

With pain being the major drawback and reason for patient dropouts in orthodontic treatment, its management becomes an essential part of orthodontics. Patients commonly use nonsteroidal anti-inflammatory drugs (NSAIDs) such as paracetamol, Ibuprofen, Diclofenac-sodium, Acetylsalicylic acid, and Celecoxib to alleviate orthodontic pain. However, it has shown that the use of these drugs has a significant effect on the orthodontic movement of teeth.Arnica montana is an accepted remedy in homeopathic medicine since concentrated extract of Arnica can be toxic, only homeopathic pellets which contain extremely diluted concentration of drug are considered appropriate for ingestion.Arnica has shown efficiency in treating inflammation and associated pain. It has a wide scope in the field of dentistry and can be used as an alternative to NSAIDs in order to control intra-operative and post-operative pain without hampering orthodontic tooth movement. Arnica 30° C can be used for the treatment of dental pain.
India is immersed in several simultaneous battles over the regulation and control of information. While the COVID-19 pandemic has ignited concerns over state-mandated information gathering of the health and personal information of residents, the expanded use of the Aadhaar biometric identity system threatens to make it an essential cipher for every interaction between the state and citizens. At the same time, the earlier momentum towards building strong legislative mandates to disclose public information to promote government accountability and enhance service delivery appears to have stalled. Further, the legislative efforts to regulate both public and private use of personal and non-personal information proceeds at a glacial pace. While these developments occur in different containers and niches of the legal ecosystem, they are grounded in one common conceptual, philosophical and legal puzzle: how should we regulate the access to, and the use of, information by public and private actors? This question becomes all the more salient with the surge in new forms of information collection and processing at a speed and scale made possible by big data collection and algorithmic decision-making technologies. ‘The Philosophy and Law of Information Regulation in India’ project is an effort to collate inter-disciplinary scholarship on the subject of the law and philosophy of information regulation, with a specific focus on India. We recognise that such an effort cannot be bound by legal scholarship alone, and must encompass and contend with the normative assumptions of various approaches towards information technologies.
Understanding, researching, and responding to this phenomenon of algorithmic harm and injustice requires a researcher to delve into cross-disciplinary scholarship and research methods which interrogate algorithmic systems as a site of critical research. A researcher must understand how these algorithmic systems in different contexts shape culture and society and what values they dislocate, unsettle, or reproduce. This brief guide is intended to introduce researchers to fundamental concepts and research methods in the emergent, nascent, and widely interdisciplinary terrain of studying 'algorithms'. It will explain why 'algorithms' are important to consider as an object of social science research and particularly how they disturb widely held values, including conceptions of ethics, fairness, transparency, accountability, and justice, across contexts. It will introduce students to various methodologies for conducting research into algorithmic systems online, with a focus on understanding how these systems might be examined for their impact on various values. Conceptualising Values and Harm in Algorithmic SystemsTo understand and conceptualise algorithmic injustice, we must start with the concept of the algorithm. What is an algorithm? A definition taken from a computer science textbook might describe an algorithm as 'any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. An algorithm is thus a sequence of computational steps that transform the input into the output'.
Any Orthodontic treatment aims to achieve desired tooth movement with a minimum number of undesirable side effects. Since the beginning of specialty, strategies for anchorage control have been a main consideration in accomplishing successful orthodontic treatment. For a long time, Orthodontists have struggled to achieve effective anchorage control. The current paper highlights various aspects of miniscrew usage like ideal requirements, fundamentals of design, indications, concepts & controversies, limitations, safe zones, placement protocols, anatomic considerations and complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
