Microabrasion remineralization
This document presents a case report on using microabrasion and remineralization (MAB-RE) to treat dental fluorosis. A 12-year-old patient presented with brown-yellow stains on their teeth due to moderate fluorosis. Over 10 weeks, microabrasion was performed using acid etching and pumice, followed by application of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) cream. This non-invasive technique successfully removed the stains without removing tooth structure. The combination of microabrasion and remineralization provides a conservative long-term approach for treating enamel defects from conditions like dental fluorosis.
Introduction to fixed partial denture

It also discusses rare ocular complications that can occur from inadvertent injection into blood vessels supplying the eye. Prevention and management strategies are provided for each complication. Systemic complications from overdose or allergy are also briefly covered. Predisposing factors that can increase risks of complications are outlined.
case history in prosthodontics
This document outlines the components of a case history for prosthodontic treatment planning. It discusses collecting patient information such as name, age, sex, occupation, etc. It also describes examining the patient extraorally and intraorally, including assessing facial form, lip support, the temporomandibular joint, and neuromuscular function. Taking a thorough case history and clinical examination allows the clinician to determine the patient's diagnosis and develop an appropriate treatment plan.
Radiographs in endodontics
Radiography is essential for endodontic diagnosis, treatment, and evaluation of treatment outcomes. It helps determine pulpal and periapical pathology, root and canal morphology, working lengths, location of missed canals, and quality of obturation. Key radiographic views include diagnostic, working length, post-treatment, and recall films. Diagnostic films aim to visualize 3-4mm beyond the apex to identify lesions. Angulation and tube shift techniques help differentiate superimposed structures. Features like lamina dura continuity, lesion borders, density and effects on adjacent structures aid diagnosis. Newer technologies include digital radiography and cone beam CT for improved visualization of complex anatomy.
Post and core
A post and core restoration is used to build up tooth structure for a crown when there is not enough structure remaining. A post is placed in the root canal and a core is built up around the post to provide support and retention for the crown. Key factors in post and core design include post length and diameter, surface texture, and luting agents to provide retention, as well as post design and cement layer to provide resistance to stresses. Custom post and cores are made using direct or indirect techniques involving impression taking, while prefabricated posts are used for circular root canals.
External root resorption (ERR)
This document discusses the different types of root resorption, including external root resorption. External root resorption is classified into external surface resorption, external inflammatory resorption, external replacement resorption, and external cervical resorption. External surface resorption is a self-limiting resorption caused by trauma or orthodontic treatment. External inflammatory resorption is often seen radiographically as an extensive lesion caused by necrotic pulp. External replacement resorption replaces the root surface with bone in a process called ankylosis. External cervical resorption is a localized resorptive lesion of the cervical area that may progress in an apical or coronal direction.

space-maintainers-pedo
Space maintainers are appliances used to maintain space or regain minor amounts of space lost after a primary tooth is lost. There are several types of space maintainers including fixed appliances like band and loop, lingual arch, and distal shoe appliances as well as removable partial dentures. Key factors in determining the appropriate space maintainer include the amount of time since tooth loss, dental age of the patient, amount of bone covering the unerupted tooth, and sequence of eruption of surrounding teeth. Space maintainers aim to guide unerupted teeth into proper positions and prevent over-eruption of opposing teeth.
fixed dentures.pdf
Fixed dentures are dentures that are permanently fixed in the oral cavity and cannot be removed without help from a dentist. They can be permanently cemented to a patient's own teeth or implanted abutments, or mounted on pillar implants with screws allowing for removal. Common types of fixed dentures include crown inlays, cast dowel crowns, veneers, crowns, and prosthetic bridges. Proper preparation of abutment teeth is important for fixed dentures and involves reducing tooth tissues while maintaining anatomical shape and creating parallel axial walls slightly converging at the chamfer.

SEMINAR ON POST AND CORE pdf.pdf
This document provides an overview of post and core restorations for endodontically treated teeth. It discusses the history and evolution of post systems from the 18th century use of metal posts to modern fiber-reinforced posts. The key components of a post and core restoration are described, including the post, core, and final crown. Guidelines for evaluating a tooth for post placement are outlined, considering endodontic, periodontal, restorative, esthetic, and radiographic factors. The rationale and indications for using posts to retain cores and provide retention, protection and marginal integrity are explained. Contraindications include abnormal root anatomy and extensive caries.
Temporary removable partial dentures
Temporary removable partial dentures are used for a limited period of time until a more definitive prosthesis can be provided. They serve several objectives like reestablishing esthetics, maintaining space, improving patient tolerance, and conditioning tissues. Some common types of temporary RPDs include interim, transitional, treatment, and immediate RPDs. Acrylic partial dentures are lightweight alternatives to metal partial dentures that are less expensive and easier to construct but also weaker and less hygienic. Their design incorporates acrylic resin, acrylic teeth, and wire clasps.
21-temporarypartialdentures.pdf
Temporary removable partial dentures are interim prostheses used until a definitive prosthesis can be provided. They aim to reestablish esthetics, maintain space, improve tolerance to wearing a prosthesis, and condition tissues. Different types include interim, transitional, treatment, and immediate RPDs. Acrylic RPDs are made with a resin base and acrylic teeth connected with wire clasps. They are indicated when cost is a concern or temporary use is needed. Care must be taken to minimize tissue damage and maintain oral hygiene with acrylic RPDs.

Prosthodontic management of endodontically treated teeth [autosaved]
1. An endodontically treated tooth can function well if restored properly, but special techniques are needed due to loss of tooth structure from previous treatments.
2. Factors such as root length, tooth anatomy, amount of remaining coronal structure, and stress factors must be considered when selecting a post and core system.
3. Post options include custom cast posts or prefabricated posts made of metal, fiber-reinforced composite, carbon fiber, or zirconia. Core materials include cast cores or direct cores made of amalgam, composite, or glass ionomer cement.
Space Maintainers in Paedodontics and Orthodontics
Space maintainers are appliances used to maintain space or regain minor amounts of space lost after premature loss of primary teeth. They are classified as fixed or removable, and include band and loop appliances, lingual arches, distal shoes, and removable partial dentures. Key considerations for use of space maintainers include the time elapsed since tooth loss, dental age of the patient, and amount of bone covering unerupted permanent teeth. Space maintainers are intended to guide eruption of permanent teeth into proper positions and prevent undesirable shifting of teeth.
Immediate Denture
An immediate complete denture is a dental prosthesis constructed to replace the lost dentition and associate structure of the maxillae and/or mandible and inserted immediately following removal of remaining teeth.

Amalgam vs composites
This document compares the two most commonly used restorative dental materials: amalgam and composites. Amalgam is a metallic material that is a mixture of silver alloy and mercury. It has high compressive strength, excellent wear resistance, and is economical. However, it is non-aesthetic and can corrode. Composites are highly cross-linked polymeric materials that are bonded to tooth structure. They offer aesthetic restorations and conserve tooth structure, but have drawbacks like polymerization shrinkage, increased time to cure, and difficulty finishing and polishing. The document discusses the compositions, applications, advantages, and disadvantages of both amalgam and composites to provide a thorough comparison of these important restorative materials.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

ESA/ACT Science Coffee: Diego Blas - Gravitational wave detection with orbita...Advanced-Concepts-Team
Presentation in the Science Coffee of the Advanced Concepts Team of the European Space Agency on the 07.06.2024.
Speaker: Diego Blas (IFAE/ICREA)
Title: Gravitational wave detection with orbital motion of Moon and artificial
Abstract:
In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
