The temporomandibular joint (TMJ) is a complex joint that connects the mandible to the temporal bone. It has three parts: the condyle of the mandible, the articular disc, and the glenoid fossa-articular eminence of the temporal bone. The TMJ is a synovial joint that allows hinge-like and gliding motions to facilitate functions like chewing and speaking. It continues developing postnatally, with the condyle and articular eminence growing in size and complexity through childhood and adolescence. The articular disc divides the joint cavity and aids in load distribution and lubrication during jaw movements.
Tmj examination & imaging
TMJ is a ginglymo-diarthroidal joint that is freely mobile with superior and inferior joint spaces separated by articular disc.
The type of imaging technique depends upon the clinical problems associated, so either imaging of hard tissue (OSSEOUS) or soft tissue is desired.
Certain protocols are to be taken care before the imaging procedure:
the amount of diagnostic information available from particular imaging modality.

Rationals of endodontics best ppt
This document discusses the rationale for endodontic treatment. It begins by explaining the theories of how infections spread from dental sources. Microorganisms enter the pulp through cavities or cracks and cause inflammation. Inflammation results in changes to the pulp and surrounding tissues. The immune system responds through nonspecific inflammatory cells and antibodies. Endodontic treatment aims to remove irritants from the root canal system and seal it to prevent further irritation and allow healing of periapical tissues.
TMJ surgical anatomy and applied aspects
The temporomandibular joint (TMJ) allows for hinge and gliding motions that facilitate functions like chewing and speech. It is a synovial joint containing features like bone, fibrocartilage discs, fluid-filled cavities, and ligaments. The TMJ is unique in that its surfaces are covered by fibrocartilage instead of hyaline cartilage and it is the only joint with a rigid closure point provided by tooth occlusion. Development of the TMJ occurs relatively late in utero, beginning with the formation of cartilaginous condyles that later ossify and fuse to the mandible.
Kaban protocol tmj ankylosis treatment orignal 1990
This document presents a protocol for managing TMJ ankylosis through seven steps: 1) aggressive resection of ankylotic tissue, 2) ipsilateral coronoidectomy, 3) contralateral coronoidectomy if needed, 4) lining the glenoid fossa, 5) reconstructing the ramus with a costochondral graft, 6) securing it with screws, and 7) early mobilization and physiotherapy. It reviews past techniques for ankylosis that often achieved less than 35mm of opening and discusses complications. The results of this protocol showed effectiveness in treating TMJ ankylosis by achieving normal function in most patients.
Maxillary sinus
Maxillary sinus is the largest of the paranasal sinuses. It develops from a shallow groove in the maxilla and reaches its maximum size by age 18. It has multiple walls and communicates with the nasal cavity via the osteum. Maxillary sinusitis can result from dental issues like periapical abscesses, cysts, foreign bodies or trauma. Odontogenic tumors and cysts can also involve the maxillary sinus. Care must be taken during dental procedures near the maxillary sinus to prevent oroantral communications.
Temporomandibular joint disorders I
1) The temporomandibular joint (TMJ) is a synovial joint that connects the mandible to the temporal bone. It has several parts including the articular eminence, fossa, condyle, capsule, ligaments, synovial fluid, and articular disc.
2) The articular disc sits between the condyle and fossa and divides the joint into two compartments. It allows the condyle to glide forward during opening and back during closing.
3) Four jaw muscles work in coordination to produce movements like opening, closing, protruding, and grinding. The lateral pterygoid muscle plays a key role in pulling the disc as the jaw opens

However, based on location and imaging features such as extension between the carotid arteries, it was determined to be a second branchial cleft cyst. The document discusses branchial arch embryology and anomalies that can result from incomplete obliteration of clefts, including branchial cysts. Branchial cysts most commonly involve the second arch and present as painless swellings in
Tumours of the parapharyngeal space
The parapharyngeal space lies laterally on either side of the pharynx and contains fat and connective tissue. It is divided into prestyloid and poststyloid compartments. Tumors in this space can be salivary gland tumors, usually pleomorphic adenomas arising from the deep lobe of the parotid gland in the prestyloid compartment. Neurogenic tumors like schwannomas and paragangliomas commonly involve the poststyloid compartment. Symptoms include a neck mass or bulging in the pharynx. Imaging helps characterize the tumor and surgical approaches aim to completely remove the tumor while preserving nearby structures.

Dental plaque
Dental plaque is a biofilm that forms on teeth. It progresses from an initial bacterial coating to a mature biofilm with complex microbial communities. Early plaque is predominantly gram-positive cocci while mature plaque contains more gram-negative rods and anaerobes. Plaque composition changes with periodontal disease, shifting from gram-positive to gram-negative and non-motile to motile organisms. Plaque initiates periodontal diseases through its noxious metabolic byproducts and through stimulating the host immune response, ultimately leading to tissue destruction if left unchecked.
Furcation involvement
This document discusses furcation involvement in multi-rooted teeth. It defines furcation as the anatomic area where tooth roots diverge, which can be difficult to clean. The document classifies furcation involvement into various grades based on the amount of bone loss and discusses clinical features, diagnosis, and various surgical treatment options like furcationplasty, tunneling, root resection, and guided tissue regeneration depending on the grade of involvement. Maintaining good oral hygiene is important for prognosis. The goal of management is to eliminate periodontal defects in the furcation area through various regenerative and resective procedures.
Immunity & Inflammation
This document provides an overview of immunity and inflammation. It discusses the key cells involved, including macrophages, mast cells, neutrophils and lymphocytes. It describes the different types of immunity (active vs passive) and inflammation (acute vs chronic). The document outlines the major chemical mediators of inflammation, including histamine, prostaglandins, cytokines and nitric oxide. It also summarizes the different immune responses and mechanisms, such as the four types of hypersensitivity reactions. Overall, the document provides a comprehensive review of the major concepts relating to immunity and inflammation.
Junctional epithelium
The document discusses the junctional epithelium (JE), which is a non-keratinized stratified squamous epithelium that adheres to the tooth surface at the base of the gingival crevice. It outlines the history of terminology used to describe the JE from 1915 to 1971. It describes the boundaries, length, shape, and cell layers of the JE. Finally, it notes some key functions of the JE, including acting as a barrier, allowing gingival crevicular fluid flow, providing attachment to the tooth, and secreting antimicrobial peptides.
Defense mechanisms of gingiva
The document discusses the defense mechanisms of the oral cavity, including saliva, gingival crevicular fluid (GCF), and the junctional epithelium. Saliva contains enzymes, antibodies, and other proteins that help protect against bacteria and viruses. GCF contains leukocytes, immunoglobulins, and enzymes that fight microbial infection in the gingival sulcus. Both saliva and GCF play important roles in the innate immune defense of the oral cavity.
Inflammation
This document provides an overview of inflammation. It defines inflammation and describes the signs and types, including acute and chronic inflammation. For acute inflammation, it details the vascular events of altered microvasculature, including hemodynamic changes and increased vascular permeability. It also describes the cellular events of exudation of leukocytes and phagocytosis. It lists the chemical mediators of inflammation released by cells and originating from plasma. It discusses the regulation of inflammation and factors determining the inflammatory response. It outlines the morphology, systemic effects, and fate of acute inflammation. It defines chronic inflammation and describes its causes, features, types, histological features, and systemic effects.
Hypersensitivity
Dentin hypersensitivity is characterized by short, sharp pain from exposed dentin in response to stimuli like heat, cold, sweets or sour foods. Several theories explain this phenomenon, but the hydrodynamic theory of fluid movement in dentinal tubules upon stimulus is most widely accepted. Dentin hypersensitivity has various causes like gum recession, tooth grinding, dental procedures or caries. Diagnosis involves case history and clinical tests. Management depends on severity and includes desensitizing toothpastes, varnishes, restorations or endodontic therapy. Preventive methods focus on diet, oral hygiene and minimizing further tooth structure loss.
Principles of periodontal instrumentation [autosaved]
The document discusses the principles of periodontal instrumentation. It covers topics like accessibility, visibility, illumination, retraction, instrument stabilization, grasps, finger rests, instrument activation, conditioning and sharpening of instruments. It emphasizes the importance of following these principles for appropriate periodontal treatment. Instrumentation requires proper patient and operator positioning, visibility, stability of instruments, adaptation, angulation, strokes and maintenance of a clean field. Various grasps, finger rests, types of strokes and sharpening techniques are described.
Smoking & its effects on periodontium
Smoking has significant negative effects on periodontal health and outcomes of periodontal treatment. It increases the prevalence and severity of periodontal disease, affects the pathogenesis by altering the microbiome and inflammatory response, and decreases the response to nonsurgical and surgical periodontal therapies. Dentists play an important role in educating patients on the harms of smoking and counseling those who use tobacco on methods for cessation using pharmacotherapy and behavioral support. Smoking cessation improves periodontal treatment outcomes by allowing the periodontium to recover.
Clinical examination of gingiva
This document provides information on describing gingival characteristics. It discusses the normal color, size, consistency, contour, surface texture, and position of gingiva. It describes changes seen in these characteristics due to various inflammatory and non-inflammatory conditions. Treatment approaches for conditions that alter gingival characteristics are also summarized, such as procedures for depigmentation and techniques for treating gingival recession.
Cementum ppt
This document provides information on cementum, which is the mineralized tissue covering the roots of teeth. It begins at the cemento-enamel junction and extends to the root apex. There are different types of cementum based on cellularity and the presence of fibers, including acellular, cellular, and intermediate cementum. Cementum is composed of collagen fibers, ground substance, and may contain cementocytes. It provides various functions such as attachment of periodontal ligament fibers and protection of the tooth root.
Mobile dentistry
1) Mobile dental clinics aim to provide oral healthcare to underserved rural populations who lack access. They are equipped with dental chairs, instruments, and sometimes X-ray machines.
2) Smile Train is an organization that focuses on providing free cleft lip and palate surgery to children in developing countries. Since 2000, they have provided over 450,000 free surgeries in India and conduct 50,000 surgeries annually.
3) Proposed models for mobile dental clinics involve partnerships between dental schools and NGOs to establish a schedule to serve villages, with oversight from local health authorities. This could ensure all villages receive biannual care.
Periodontal ligament
The document discusses the periodontal ligament (PDL), which is a specialized connective tissue that surrounds tooth roots and attaches them to the alveolar bone. It provides definitions of the PDL, describes its development, structure, cellular components, principal fibers, blood supply, and functions. The PDL maintains the space between the root and bone despite forces on the teeth and is composed of fibroblasts, extracellular fibers and ground substance that connect the cementum and alveolar bone. It summarizes the key anatomical and functional aspects of the PDL.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.share - Lions, tigers, AI and health misinformation, oh my!.pptx

Novas diretrizes da OMS para os cuidados perinatais de mais qualidade
Novas diretrizes da OMS para os cuidados perinatais de mais qualidadeProf. Marcus Renato de Carvalho
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
