Acute Necrotising Ulcerative Gingivitis
Acute necrotising ulcerative gingivitis is a rare condition characterized by necrosis of the gingiva and interdental papillae. It frequently occurs during times of stress and poor oral hygiene. The condition is caused by fusiform bacillus and Borrelia vincentii bacteria. Clinically, the gingiva becomes painful and develops punched-out ulcers. It can spread to other oral tissues and rarely the skin, causing further complications.
Recurrent aphthous stomatitis
Recurrent aphthous stomatitis (RAS) is the most common oral ulcerative condition, affecting 1 in 5 individuals. It is classified into minor, major, and herpetiform ulcers, with minor ulcers being the most common. The pathogenesis involves an abnormal T-cell mediated immune reaction, though the exact cause is unknown. Certain factors like nutritional deficiencies, infections, genetics, and trauma may contribute to disease development or severity. RAS is diagnosed based on clinical examination and history. Treatment involves managing pain and preventing infections, with some evidence that vitamin B12 supplementation may help resolve ulcers.
Vesiculobullous
This document describes vesiculo-bullous lesions, which present clinically as vesicles or bullae that often rupture early, appearing as ulcerated or erosive areas. Some key points:
- Vesicles are fluid-filled lesions less than 1 cm, while bullae contain fluid and are over 1 cm.
- Causes include trauma, infection, autoimmunity, and genetic factors.
- Examples described include herpes simplex infection, varicella zoster infection, and hand foot and mouth disease. Clinical features, pathogenesis, management are provided for each. Classification is discussed based on acute vs chronic presentation, clinical presentation, and histopathological location.
Mucocutaneous
This document discusses various mucocutaneous disorders of the oral cavity, including genodermatoses, infective causes, and non-infective conditions.

It provides details on the pathogenesis, clinical features, radiographic appearance and histology of specific cysts such as dentigerous cysts and odontogenic keratocysts. Dentigerous cysts are defined as cysts originating from the separation of the dental follicle from around the crown of an unerupted tooth. Odontogenic keratocysts are distinctive cysts that arise from cell rests of the dental lamina and have more aggressive behavior than other cysts. Complications of cysts include recurrence, development of
ANUG
This document discusses Necrotizing Ulcerative Gingivitis (NUG), also known as trench mouth. It defines NUG as a microbial disease of the gingiva caused by an impaired host response. Key clinical features include necrosis of gingival tissue and pain. Diagnosis is based on these clinical findings and microscopic examination. Management involves reducing the microbial load, removing necrotic tissue, treating any systemic conditions, and supportive periodontal therapy. Prognosis is generally good with treatment but recurrence is possible without ongoing maintenance of oral hygiene.
Abnormalities of the pulp
The document summarizes various abnormalities and diseases that can affect the dental pulp and periapical tissues, including:
1) Pulp calcification, which involves mineralization within the pulp chamber or root canals and can occur as denticles, pulp stones, or diffuse linear calcifications.
2) Resorption of teeth, which can be physiological for deciduous teeth but pathological for permanent teeth.
3) Diseases of periapical tissues including periapical abscesses, granulomas, radicular cysts, phoenix abscesses, and condensing osteitis. These conditions are responses to dental infection and inflammation and can develop from other lesions if left untreated.
Dentinogenesis Imperfecta
Dentinogenesis imperfecta is a hereditary condition that affects the formation of dentin in both primary and permanent teeth. It is classified into two main types - dentinogenesis imperfecta type 1 and type 2. Type 1 is caused by mutations in the DSPP gene and affects only the teeth. Type 2 may be caused by mutations in two tightly linked genes and is characterized by multiple pulp exposures and shell-like teeth. Treatment aims to prevent wear of enamel and dentin through full coverage restorations.
Pulpitis
This document discusses different types of pulpitis and periapical inflammation. It defines pulpitis as inflammation of the dental pulp that can be acute or chronic. Acute pulpitis is further divided into reversible and irreversible types based on whether the inflammation is localized or involves the entire pulp. Chronic pulpitis can be closed or open (hyperplastic). Periapical inflammation ranges from granulomas and cysts to abscesses. Diagnosis involves x-rays and pulp testing to evaluate the pulp chamber and periapical region. Treatment depends on the specific condition but may include removal of irritants, root canals, drainage or extraction.
Pulipitis
The document discusses diseases of the dental pulp, including pulpitis and necrosis. It defines the pulp as the formative organ of the tooth that builds dentin. Pulpitis is the most common cause of dental pain and can be reversible or irreversible depending on the severity of inflammation. Untreated pulpitis can lead to necrosis or death of the pulp. Causes include mechanical, thermal, chemical, and bacterial factors. Management involves removal of irritants and root canal treatment if needed.
ORAL VESICULOBULLOUS LESION

It discusses conditions like pemphigus vulgaris, pemphigoid, paraneoplastic pemphigus. Pemphigus vulgaris involves autoantibodies against desmogleins 1 and 3, causing blistering in skin and mucosa. Paraneoplastic pemphigus is associated with neoplasms and involves multiple organs. Diagnosis involves biopsy, DIF, and ELISA to detect specific autoantibodies.
PERIODONTAL ABSCESS
This document provides an overview of abscesses of the periodontium, specifically focusing on periodontal abscesses. It defines a periodontal abscess and classifies them based on location, course, number, affected tissue, and cause. Periodontal abscesses are most prevalent in molar sites and those with pre-existing periodontal pockets. They can be caused by factors like untreated periodontitis, foreign bodies, or changes after periodontal procedures or antibiotics. The pathogenesis involves bacterial entry triggering an inflammatory response that leads to tissue destruction and pus formation.
Cysts in orofacial region
Cysts in orofacial regions were discussed. Key points include:
1. Cysts are pathological cavities lined by epithelium and filled with fluid/semi-solid material. Common types are odontogenic cysts like dentigerous and keratocysts.
2. Dentigerous cysts form between reduced enamel epithelium and tooth crown, associated with unerupted teeth. Keratocysts have high recurrence rates due to thin fragile lining.
3. Treatment options are marsupialization to shrink large cysts, and enucleation to remove the cyst lining along with the associated tooth/teeth.
Peripheral giant cell granuloma (giant cell epulis
The document discusses two types of giant cell lesions of the jaw: peripheral giant cell granuloma (PGG) and central giant cell granuloma (CGG). PGG is a reactive lesion caused by local irritation or trauma that occurs on the gingiva. CGG is a benign process that occurs within the jaw bones and can be non-aggressive or aggressive depending on symptoms and growth rate. Both lesions contain multinucleated giant cells and are treated with surgical excision, with CGG having a slightly higher recurrence rate. Key distinguishing features and histological characteristics are provided.
Necrotizing ulcerative gingivitis
Necrotizing gingivostomatitis is an inflammatory condition affecting the gingiva and mouth that is caused by fusiform bacteria and spirochetes. It is characterized by painful, red gingiva with crater-like sores between teeth, bleeding gums, bad breath, and fever. Examination of affected tissue shows many bacteria and white blood cells. Histologically, there is gingival ulceration and necrosis with an inflammatory cell infiltrate. Treatment involves cleaning the mouth with antiseptics followed by scaling and antibiotics to resolve the infection.

gingiva
The gingiva is the mucosa that covers the alveolar bone and surrounds the necks of teeth. It consists of marginal gingiva, attached gingiva, and interdental gingiva. The marginal gingiva forms a collar around each tooth. The attached gingiva is firm and resilient, attaching the gingiva tightly to the underlying bone. The interdental gingiva occupies the spaces between teeth. Microscopically, the gingiva contains keratinized oral epithelium, non-keratinized sulcular epithelium, and junctional epithelium that extends along the tooth surface.

También describe signos y síntomas de gingivitis como enrojecimiento, hinchazón y sangrado de las encías. Finalmente, distingue entre gingivitis inducida y no inducida por placa, mencionando algunas caus
Dental caries ppt
Dental caries is caused by bacterial damage to teeth from plaque and acid production when exposed to fermentable carbohydrates like sugar. The major bacteria involved are Streptococcus mutans and lactobacilli, which adhere to teeth and produce acid from sugars, lowering the pH and demineralizing enamel and dentin. If left untreated, caries can spread to the pulp, causing inflammation and pain. Consequences of untreated dental caries include local infections and possible systemic illnesses.
Periodontal Diesase Classification (presentation)
The document discusses the classification of periodontal diseases. It provides an overview of how periodontal diseases were previously classified, noting that the classification system was heavily based on age. It then summarizes the updated 1999 classification system, which introduced categories for gingival diseases and refined the categories for periodontal diseases. The key changes were introducing gingival disease categories, replacing terms like "adult periodontitis" with "chronic periodontitis", and expanding definitions of systemic diseases and their implications for periodontal health.

Kaposi Varicelliform Eruption
Kaposi's varicelliform eruption is a rare disseminated form of herpes simplex virus infection that can occur in patients with chronic skin diseases or immunosuppression. It presents with hemorrhagic vesicles, pustules, erosions and scabs predominantly on the head and neck, along with high fever, malaise and lymphadenopathy. Diagnosis involves culture, PCR or biopsy with treatment consisting of antiviral medications like acyclovir or valaciclovir and antibiotics.
Enamel pearl
An enamel pearl, or enameloma, is a small white mass of ectopic enamel attached to a root surface near the cementoenamel junction (CEJ). It can contain enamel, dentin, and pulp. Enamel pearls are caused by the persistence of Hertwig's epithelial root sheath during root development, allowing it to form enamel. They range in size from 0.3 to 4 mm and commonly form on the maxillary and mandibular molars. Enamel pearls promote plaque retention and provide a niche for bacteria, which can lead to periodontal problems if left untreated.
Clindamycin
Clindamycin is a lincosamide antibiotic produced by Streptomyces lincolnensis. It works by binding to the 50S ribosomal subunit and inhibiting bacterial protein synthesis. It is well absorbed orally and achieves high tissue concentrations. Common uses include skin and soft tissue infections, dental infections, and anaerobic infections. Side effects include pseudomembranous colitis. It should not be used for trivial infections or in patients with a history of inflammatory bowel disease.

Bednar’s aphthae
Bednar's aphthae is an infantile oral ulcerative disease characterized by ulcers localized to the hard palate that typically occur within the first week of life. The ulcers are caused by trauma from improper feeding positions and methods, such as bottle feeding with formula that is too hot or using bottles with narrow nipple holes. The ulcers usually cause feeding intolerance and irritability in infants until resolving spontaneously with corrected feeding techniques.
Amelogenesis imperfecta
Amelogenesis Imperfecta is a condition affecting the development of dental enamel. It has several classifications depending on the specific enamel defect present, including hypoplastic (inadequate enamel), hypocalcified (no mineralization), and hypomaturation (failure of enamel to mature). The condition can be inherited in autosomal dominant, recessive, x-linked, or sporadic patterns. Diagnosis is based on family history, clinical examination showing discolored, sensitive teeth prone to disintegration, and radiographic findings of abnormal enamel appearance. It may occur alone or be associated with other systemic abnormalities in syndromes.

PGx Analysis in VarSeq: A User’s Perspective
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.
Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.

- 7. It is commoner in:
- 9. Pathogenesis
- 14. • Characteristics of aphthous ulcers which are indicative of infectious etiology include recurrent ulceration, lymphocytic infiltration, perivascular cuffing, presence of auto-antibodies, inclusion bodies in case of herpetiform ulcers and similarity of RAS to viral ulcerative diseases in animals.
- 16. Minor aphthae (Mikulicz ulcers)
- 18. Major aphthae (Sutton’s ulcers)
- 20. Herpetiform aphthae (Cooke’s ulcers) They recur so frequently that ulceration may be virtually continuous.
- 22. • There could be more than one type in a patient but that would herald an underlying systemic problem • The usual combinations seen would be major + herpetiform and may be the first sign of the disease in up to 75% of cases • Sometimes the ulcerations can be the only sign of celiac disease •Mikulicz>Cooke>Sutton
- 25. Pre-ulcerative stage is predominantly lymphocytic infiltrates with initial CD4 preponderance. Later CD8+ outnumbers CD4+. Mainly in a perivascular distribution
