Study Notes

Odontogenic cysts Odontogenic cysts are lined with epithelium derived from the following tooth development structures: • rests of Malassez: radicular cyst, residual cyst • reduced enamel epithelium: dentigerous cyst, eruption cyst • Remnants of the dental lamina: Odontogenic keratocyst, lateral periodontal cyst, gingival cyst of adult, glandular odontogenic cyst Radicular cyst          Radiology - A w…

Some important points about the periodontal pocket : ·Soft tissue of pocket wall shows both proliferative & degenerative changes ·Most severe degenerative changes are seen on the lateral wall of pocket ·Plasma cells are the predominant infiltrate (80%). Others include lymphocytes & a scattering of PMNs ·Height of junctional epithelium shortened to only 50-100µm ·Severity of degenerative changes is not linked to pocket depth ·Junctional epithelium sta…

Antianginal Drugs Organic Nitrates : Short acting: Glyceryl trinitrate (Nitroglycerine, GTN), Amyl Nitrate Long Acting: Isosrbide dinitrate (Short acting by sublingual route), Erythrityl tetranitrate, penta erythrityl tetranitrate Beta-adrenergic blocking agents : Propanolol, Metoprolol Calcium channel blockers Verapamil, Nifedipine, Dipyridamole   Mechanism of action  – Decrease myocardial demand  – increase blood supply to t…

LIPOPROTIENS Lipoproteins Consist of a Nonpolar Core & a Single Surface Layer of Amphipathic Lipids The nonpolar lipid core consists of mainly triacylglycerol and cholesteryl ester and is surrounded by a single surface layer of amphipathic phospholipid and cholesterol molecules .These are oriented so that their polar groups face outward to the aqueous medium. The protein moiety of a lipoprotein is known as an apolipoprotein or apoprotein,constituting nearl…
