EndodonticsObtura II is a high heat obturation technique used in endodontics (root canal treatment) to fill and seal the root canal system of teeth. This technique involves the use of a thermoplasticized gutta-percha, which is heated to a high temperature and then compacted into the root canal with a heat source such as a heated plugger or a heated tip of a handpiece. The heat helps to soften the gutta-percha, allowing it to adapt to the irregularities of the root canal system and form a tight seal against bacterial microleakage. Thermofill and Ultrafill are not high heat techniques, while sectional filling is a method of filling the canal in increments, which may or may not involve heat.

Pharmacology
ACE inhibition has a beneficial impact on survival rates, functional status, and hemodynamics in patients with left ventricular systolic dysfunction.
In the renin-angiotensin system, a fall in perfusion pressure stimulates the juxtaglomerular cells in the kidney to release the enzyme renin.
Renin cleaves the decapeptide angiotensin I from angiotensinogen, a glycoprotein synthesized in the liver.
The octapeptide angiotensin II is formed by the action of ACE on angiotensin I.
Angiotensin II is a potent vasoconstrictor and stimulates the release of aldosterone and norepinephrine.
