management of dentigerous cyst
•
2 likes•197 views
Dentigerous cysts originate after a tooth crown is fully formed, causing fluid accumulation between the reduced dental epithelium and tooth substance. Dentigerous cysts are typically treated based on size and whether the involved tooth can be saved. Treatment options include enucleation, marsupialization, or a staged combination of the two. Enucleation involves total removal of the cyst and tooth, while marsupialization creates a window to drain the cyst contents while maintaining the tooth. A staged approach uses marsupialization followed by later enucleation to potentially save the tooth.

Management of oroantral fistula
- Oroantral fistula is an abnormal communication between the maxillary sinus and oral cavity, usually resulting from tooth extraction or trauma.
- Symptoms include sinusitis, nasal discharge, pain, and escape of air/fluid through the nose or mouth. Diagnosis involves clinical exam, nasal blowing test, and radiographs.
- Treatment depends on whether the fistula is fresh or established. Immediate closure of small fistulas is attempted using sutures to hold a blood clot. Larger fistulas require local flaps like buccal or palatal flaps to close the defect without tension. Delayed fistulas may need grafting if bone is missing.
Dry socket
Dry socket, also known as alveolar osteitis, is a painful condition that can occur after a dental extraction. It results from the premature disintegration of a blood clot within the extraction socket, preventing normal healing. Risk factors include difficult extractions, oral contraceptive use, smoking, and poor oral hygiene. Clinically, patients experience severe pain localized to the socket starting 2-3 days after extraction along with bad breath. Two main theories propose either a fibrinolytic or bacterial cause that disrupts the blood clot formation and healing. Management focuses on irrigation, placement of medicated dressings, analgesics, and potentially topical anti-inflammatory treatments to reduce pain and promote socket healing.

Vital pulp therapy technique
Indirect pulp capping involves removing gross caries while leaving a thin layer over the pulp to avoid exposure. It allows the remaining caries to arrest over 6-8 weeks under a restoration. Direct pulp capping is for small exposures, usually accidental, surrounded by sound dentin. Calcium hydroxide or MTA is placed directly on the exposure. Pulpotomy removes the coronal pulp for carious or mechanical exposures, with various medicaments like formocresol or MTA placed on the remaining pulp stumps. Success requires careful case selection and technique. Indirect capping and MTA pulpotomy show promise but need more long-term research for primary teeth.
Biopsy and cyst managment
The document discusses different surgical techniques for treating cysts, including enucleation which completely removes the cyst, marsupialization which creates a window to drain the cyst contents while leaving the lining intact, and enucleation with curettage which uses a bur to remove 1-2mm of bone around the cyst cavity after enucleation to eliminate any remaining epithelial cells that could cause recurrence. Marsupialization is indicated when access is difficult, a vital structure is at risk, or the patient is in poor health, while enucleation with curettage is preferred for aggressive cysts like keratocysts due to

Maxillofacial prosthesis
Maxillofacial prosthetics aims to restore function and aesthetics after defects caused by trauma, surgery, or congenital conditions. It involves both intraoral and extraoral prostheses made of materials like acrylics and silicone. Immediate prostheses are placed during or right after surgery to aid healing, while definitive prostheses are placed months later once healing is complete. Preprosthetic measures like vestibuloplasty and implants can improve prosthetic outcomes. The goal of extraoral prostheses for areas like the ear, orbit, and nose is cosmetic restoration through careful design and skin grafting or implant support if needed.
Acquired maxillary defects copy removeable
1. The document discusses palatal defects, including defining palatal defects as a lack of continuity of the palatal structure.
2. It describes the function of the velopharyngeal sphincter to close the nasopharynx and discusses Passavant's ridge.
3. Methods of reconstructing palatal defects are discussed, including denture fabrication and using different materials like wire and green compound for molding impressions. Classification systems for acquired hard palatal defects are also presented.
Maxillofacial prosthesis
This document provides an overview of maxillofacial prosthetics. It discusses the history of artificial facial reconstruction and the establishment of maxillofacial prosthetics as a branch of dentistry. Maxillofacial prosthetics aims to restore function and esthetics after trauma, surgery, or congenital defects. Prostheses can be intraoral or extraoral and may be immediate, transitional, or definitive depending on the healing process. The document outlines various prosthetic options and techniques for reconstructing parts of the maxilla, mandible, ear, nose, and orbit. It emphasizes a multidisciplinary team approach including surgeons, prosthodontists, and other specialists to optimize patient rehabilitation.
Preventive and interceptive orthodontics
This document discusses various orthodontic procedures including preventive, interceptive, and comprehensive orthodontics. It describes different types of orthodontic problems seen in children including non-skeletal (dental) problems and skeletal problems. Specific issues covered include natal teeth, occlusal relationship problems, eruption problems, space maintenance, traumatic displacement of teeth, and space-related problems. Treatment approaches are provided for each problem depending on factors such as the severity, timing, and underlying cause. Early intervention is emphasized to prevent the development or worsening of malocclusions.
Unidad 1 intro to restorative concepts revisited
1. The document discusses the history and principles of operative planning and cavity preparation for direct dental restorations. It covers topics like defining cavities versus preparations, principles of cavity design put forth by Black and others, classification of cavities, and methods for detecting and removing decay while protecting the pulp.
2. Modern cavity preparations aim to be minimally invasive using techniques like adhesive dentistry, laser diagnosis, and pulp protection with sealants or glass ionomer cements. Cavities can be classified based on location, size, depth and other factors to guide the preparation.
3. Outline, resistance, retention, convenience and cleaning steps are discussed as the logical sequence for cavity preparations to efficiently and effectively access decay while

CYSTS OF THE JAWS Part II
The document provides information about dentigerous cysts, including their definition, characteristics, and pathogenesis. Some key points:
- Dentigerous cysts originate from the separation of the dental follicle from around the crown of an unerupted tooth. They enclose the crown and are attached to the cementoenamel junction.
- They most commonly occur in males in the first to third decades of life, associated with mandibular third molars or maxillary canines. Large cysts can cause bone expansion and displacement of teeth.
- Radiographically, they appear as well-defined radiolucencies surrounding the crown of an impacted tooth. Histologically, the lining is non-

Suprarenal gland
The adrenal gland is located at the upper pole and medial border of the right and left kidneys. The right adrenal gland is triangular in shape with its hilum directed upwards, while the left is semi-lunar with its hilum directed downwards. Each gland receives arterial blood supply from three arteries: the superior, middle, and inferior suprarenal arteries. They drain venously into the inferior vena cava (right gland) or left renal vein (left gland).
PATHOGENESIS OF UPPER GIT BLEED VS LOWER GIT BLEED
Upper GIT bleed involves bleeding from the esophagus, stomach, or duodenum, with common causes being peptic ulcer disease, esophageal varices, and tumors. Lower GIT bleed involves bleeding from the small intestine, colon, rectum, or anus, with the most common causes being diverticular disease, ischemic colitis, and neoplasms. Other potential causes for both upper and lower bleeds include medications, infections, and inflammatory bowel disease.
Physiopathology of epilepsy
Hyper-excitable neurons lead to excessive excitability in surrounding neurons, causing seizures (hyper-synchronization). This occurs due to an imbalance of excitatory vs inhibitory neurotransmitters - glutamate activation and lowered calcium channel thresholds increase neuronal excitation, while reduced GABA inhibition decreases the inhibitory surround. This disruption of the normal depolarization-afterhyperpolarization cycle in neurons results in a continuous firing state and seizure focus.
local Method To Control Bleeding In Dental Office
This document discusses local methods to control bleeding in a dental office. It identifies direct pressure, mechanical methods like sutures and clips, and thermal methods like electrocautery and lasers as common techniques. Chemical hemostatic agents can also be used, such as epinephrine applied topically or injected. Collagen products, gelatin sponges, and thrombin-based topical agents further assist in clotting. Newer flowable hemostatic agents combine passive and active clotting components. If bleeding persists after initial measures, additional steps may need to be considered. Proper evaluation of a patient's medical history is important to prevent intra- and post-operative bleeding complications.
"Investigations of tooth discoloration"
This document discusses investigations into tooth discoloration. It defines tooth discoloration and outlines several laboratory studies and radiographic examinations that can be used to identify potential causes. Laboratory tests may include renal ultrasound scans, urine tests, and complete blood counts. Radiographic imaging like intraoral and panoramic x-rays can reveal defects in tooth structure and alveolar bone. Specific conditions like amelogenesis imperfecta, dentinogenesis imperfecta, and dentinal dysplasias each have distinguishing radiographic features. Histologic examination provides additional information but is not usually needed for daily clinical practice. References are provided for further reading.
How to avoid and prevent the complications of medically compromised patient
The document provides guidelines for dentists treating medically compromised patients to avoid complications. For all patients, dentists should consult physicians, use stress reduction protocols, proper pain control and sedation if needed. Specific guidelines are given for treating patients with diabetes, heart failure, and COPD. For diabetes patients, appointments should avoid peak insulin periods and blood sugar should be checked. For heart failure and COPD patients, medical conditions must be well-controlled before dental treatment and risks of stress and drug interactions considered.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
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.CLEAR ALIGNER THERAPY IN ORTHODONTICS .pptx

10 Benefits an EPCR Software should Bring to EMS Organizations
The benefits of an ePCR solution should extend to the whole EMS organization, not just certain groups of people or certain departments. It should provide more than just a form for entering and a database for storing information. It should also include a workflow of how information is communicated, used and stored across the entire organization.
MERCURY GROUP.BHMS.MATERIA MEDICA.HOMOEOPATHY
Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

management of dentigerous cyst
- 2. 2 its Defined as cyst originating after crown of a tooth is completely formed, by accumulation of fluid between .reduced dental epithelium and tooth substance
- 3. 3 Dentigerous cyst is treated according to the size of the lesion and whether or not it is desirable to save the involved tooth
- 4. 4 However, it can be treated in one of the following basic methods :
- 5. 5 1. Enucleation : Definition: 1. Total removal of a cystic lesion is achieved. 2. A shelling-out of the entire cystic lesion without rupture. 3. Enucleation of cysts should be performed with care, in an attempt to remove the cyst in one piece without fragmentation, which reduces the chances of recurrence by increasing the likelihood of total removal. 4. it involve the total removal the tooth
- 6. 6 2. Marsupialization: Definition: 1. Marsupialization, decompression, and the Partsch operation all refer to creating a surgical window in the wall of the cyst, evacuating the contents of the cyst, and maintaining continuity between the cyst and the oral cavity, maxillary sinus, or nasal cavity. 2. If the tooth is to be maintained marsupialization is stongly advocted in children 3. The only portion of the cyst that is removed is the piece removed to produce the window.
