Ameloblastoma
Odontogenic cysts and tumors are the most important topics in Oral Pathology. Ameloblastoma itself is quite a large topic to talk about.
So on a rough basis, Ameloblastomas are basically tumors. They are tumors of Odontogenic (tooth forming tissue) in origin. They are benign in nature.
I have included detailed notes for types, clinical features and histology. Treatment I shall share on a more detailed version in coming blogs.

CLINICAL PRESENTATION OF PULMONARY TUBERCULOSIS
STUDY NOTES ⚕️
Clinical Presentation:
👩⚕️ Chronic cough often with hemoptysis.
👨⚕️ Pyrexia of unknown origin.
👩⚕️ Unresolved Pneumonia.
👨⚕️ Exudative pleural effusion.
👩⚕️ Asymptomatic (diagnosis on chest radiograph)
👨⚕️ Weight loss, general debility.
👩⚕️ Spontaneous Pneumonia.
Time from infection and Manifestations:
🕗 3 – 8 weeks ➡️ Primary Complex, Positive tuberculin skin test.
🕕 3 – 6 months ➡️ Meningeal, miliary and pleural disease.
🕒 Upto 3 years ➡️ Gastrointestinal, bone and joint and lymph node disease.
🕣 Around 8 years ➡️ Renal tract disease.
🕞 From 3 years onwards ➡️ Post primary disease due to reactivation or reinfection.

Biological Considerations of Dental Materials
The biological considerations of dental materials cannot be isolated from their physical properties.
Biological requirements of Dental Materials
A dental material should:
- Be non-toxic to the body.
2. Be non-irritant to the oral or other tissues.
3. Not produce allergic reactions.
4. Not be mutagenic or carcinogenic.
Examples of hazards from chemicals in Dental Materials
✔Some dental cements are acidic and may cause pulp irritation.
✔Polymer based filling materials may contain irritating chemicals such as unreacted monomers, which can irritate the pulp.
✔Phosphoric acid is used as an etchant for enamel.
✔Mercury is used in dental amalgam, mercury vapor is toxic.
✔Dust from alginate impression materials may be inhaled, some products contain lead compounds.
✔Monomer in denture base materials is a potential irritant.
✔Some people are allergic to alloys containing nickel.
✔During grinding of beryllium containing casting alloys, inhalation of beryllium dust can cause berylliosis.
✔Some dental porcelain powders contain uranium.
✔Metallic compounds (e.g. of lead and tin) are used in elastomeric impression materials.
✔Eugenol in impression pastes can cause irritation and burning in some patients.
✔Laboratory materials have their hazards, such as: cyanide solution for electroplating, vapours from low fusing metal dies, siliceous particles in investment materials, fluxes containing fluorides, and asbestos.
✔Some periodontal dressing materials have contained asbestos fibres.
