Study Notes

Direct pulp capping is a minimally invasive endodontic procedure used to preserve the vitality of the tooth's pulp when it is exposed due to caries or trauma. The goal is to induce a biological response that leads to the formation of dentin-bridge to seal the pulp and prevent further infection. Indications: - Cariously exposed pulp that is asymptomatic and has no evidence of irreversible pulpitis. - Recent traumatic exposure of the pulp with no sign…

 Beta - Adrenergic Blocking Agents     Mechanisms of Action     - Initial decrease in cardiac output, followed by reduction in peripheral vascular resistance.  - Other actions include decrease plasma renin activity, resetting of baroreceptors,  release of vasodilator prostaglandins, and blockade of prejunctional beta-receptors.   Advantages  - Documented reduction in cardiovascular morbidity and mortality.…

Osteogenesis Imperfecta (OI) (Brittle bone diseases)  It is a group of hereditary disorders caused by gene mutations that eventuate in defective synthesis of and thus premature degradation of type I collagen. The fundamental abnormality in all forms of OI is too little bone, resulting in extreme susceptibility to fractures. The bones show marked cortical thinning and attenuation of trabeculae.  Extraskeletal manifestations also occur because type I c…
