This document discusses histochemistry of oral tissues. It defines histochemistry as the qualitative and quantitative assessment of chemicals within cells and tissues. It describes the purpose of histochemistry as coloring structures for identification, locating insoluble materials accurately in tissues, and using materials that do not separate from their environment with high sensitivity. It outlines the main oral tissues studied in histochemistry as connective tissue, epithelial linings, and glandular structures. It provides details on specific histochemical techniques used to study components like glycogen, glyoproteins, proteoglycans, lipids, proteins, nucleic acids, and enzymes in oral tissues.
This document provides information about benign neoplasms, including odontogenic and non-odontogenic tumors. It defines key terms like neoplasm and benign tumor. It then describes several specific benign odontogenic tumors in detail, including their definitions, clinical features, radiographic features, differential diagnosis, and management. These include ameloblastoma, adenomatoid odontogenic tumor, and calcifying epithelial odontogenic tumor. The document also provides classifications of benign neoplasms and images to illustrate radiographic findings.

BENIGN TUMOUR : Is a new growth, which is limited by a capsule and grows by local expansion without causing any harm to the host, excepting its position in a vital organ.
MALIGNANT TUMOUR : Is a new growth which is characterized by rapid growth, sign of invasion, absence of capsule and last of all dissemination to other parts of the body usually by hematogenous or lymphatic route or both.

This document provides information on various odontogenic tumors including:
- Ameloblastoma - A benign but locally aggressive tumor that can cause facial deformities. It has follicular and plexiform histological patterns.
- Calcifying epithelial odontogenic tumor (CEOT) - A locally aggressive tumor consisting of epithelial strands and spheres often accompanied by calcifications. It can be central or peripheral.
- Adenomatoid odontogenic tumor (AOT) - A non-aggressive lesion usually found around crowns of unerupted teeth consisting of epithelial swirls and ducts with calcifications.
The document describes clinical features, radiographic appearances, histological patterns and characteristics of these
This document provides an overview of oral submucous fibrosis (OSF), including its definition, epidemiology, etiology, pathogenesis, clinical features, classification, and medical management. OSF is characterized by fibrous bands in the oral mucosa leading to mouth opening restriction. It is commonly found in India and associated with areca nut chewing. Clinical features include blanching of the oral mucosa, trismus, and palpable fibrous bands. Staging systems exist based on clinical features and mouth opening. Management focuses on eliminating risk factors and includes antioxidants, biogenic stimulants, immune modulators, and blood flow promotors to reduce fibrosis and support healing.
This document summarizes key information about major and minor salivary glands including their location and cell types. It describes common benign and malignant epithelial tumors of the salivary glands such as pleomorphic adenoma, Warthin's tumor, oncocytoma, and mucoepidermoid carcinoma. For each tumor, the clinical features, microscopic appearance, differential diagnosis, and important histological characteristics are outlined. The document provides an overview of salivary gland anatomy, histology, and the spectrum of tumors that can arise in these glands.
A benign mesenchymal lesion that mimics microscopically the dental pulp or follicular connective tissue
Derived from odontogenic ectomesenchyme
multilocular with honeycomb pattern. Cortical plate expansion, root displacement or resorption may be seen
This document summarizes mixed odontogenic tumors, which contain both odontogenic epithelium and ectomesenchyme. It discusses three main types: ameloblastic fibroma, adenomatoid odontogenic tumor, and odontomas. Ameloblastic fibroma contains odontogenic epithelium and spindled mesenchyme that may resemble dental papilla. It typically occurs in young patients and presents as a painless swelling. Adenomatoid odontogenic tumor is characterized by epithelial duct-like structures and inductive changes in the connective tissue. It has a predilection for the anterior jaws. Odontomas are hamartomas containing fully formed dental tissues. They are the most
The document discusses tumors of the jaw, including odontogenic tumors. It defines benign and malignant tumors and provides examples of tumors that arise from different tissues. It then focuses specifically on odontogenic tumors, providing a classification system and examples such as ameloblastoma. The clinical features, diagnosis, and various treatment methods for ameloblastoma such as excision, curettage, resection, and reconstruction are summarized. Key factors that influence choice of treatment are also outlined.
This document summarizes several variants of oral squamous cell carcinoma (SCC), including verrucous carcinoma, basaloid SCC, and sarcomatoid carcinoma. It describes the histological features and sites of involvement for each variant. Key microscopic findings are outlined, such as the prominent keratin layer and pushing margins seen in verrucous carcinoma. Diagnostic criteria and differential diagnoses for each variant are also provided. The document additionally reviews adenocarcinoma subtypes seen in the oral cavity and describes patterns of bone and perineural invasion associated with oral cancers.
The document discusses various odontogenic tumors arising from odontogenic epithelium and ectomesenchyme, including both benign and malignant tumors such as ameloblastoma, calcifying epithelial odontogenic tumor, adenomatoid odontogenic tumor, ameloblastic fibroma, and odontoma. Malignant tumors mentioned include ameloblastoma carcinoma, primary intraosseous carcinoma, and odontogenic sarcoma. The document provides information on pathogenesis, clinical features, radiographic features, and histological features of these tumors.
The document discusses cysts of the jaws, including their classification and pathogenesis. It focuses on odontogenic cysts and developmental cysts. Specifically, it describes a dentigerous cyst as an odontogenic cyst that surrounds the crown of an impacted tooth, caused by fluid accumulation between the reduced enamel epithelium and enamel surface, resulting in a cyst enclosing the tooth crown. Dentigerous cysts usually involve permanent teeth, often third molars or cuspids. They present as well-defined radiolucencies associated with unerupted teeth on imaging.
Exfoliative cytology is a technique that examines shed cells from body surfaces to detect diseases. It was developed in the 1800s and applied to oral diagnosis in the 1900s. A smear is taken from oral mucosa using instruments then stained and examined microscopically. Normal cells appear organized while abnormal cells show nuclear and cytoplasmic changes. Exfoliative cytology is a non-invasive method used to screen for oral cancer and infections. It has advantages of being painless and inexpensive but lacks sensitivity compared to biopsy. New techniques using fluorescence, computer analysis, and molecular methods aim to improve accuracy of oral exfoliative cytology.
