TYPES OF SHOCK 1- Cardiogenic shock: due to acute heart failure, myocardial infarction, anaesthesia, cardiac arrest, arrhythmias …..etc

1. Intermittent claudation is caused by A. Venous occlusion B. Arterial insufficiency C. Neural compression D. Muscular dystrophy

BUERGER'S DISEASE Arterial occlusive disease mainly affecting lower limbs Occurs in men from 20-40years and in smokers Characterised by gangrene of the toes and fingers and corrugation of femoral arteries

1. A patient of burn should be given A. 5% dextrose B. Hypertonic saline 0.9% C. Dextrose saline D. Human albumin 4.5%

A burn is a wound in which there is coagulative necrosis of the tissue. Types of burns; ● Ordinary burn caused by dry heat

1.Tracheostomy will a) Increase dead air space b) Increase respiratory resistance c) Decrease respiratory work d) Cause obstruction in respiration

1.Undermined ulcer this present in a) Syphilis b) Tuburculosis c) Basal cell carcinoma d) Hodgkin’s lymphoma

Aggressive periodontitis refers to the multifactorial,severe,&rapidly progressive form of periodontitis,which is primarily but not exclusively affects younger patients.

1. Gingivectomy a) Removes supra gingival pockets b) Removes enlargements c) Removes supragingival abscess d) ALL

Gingivectomy Excision of gingiva by removing the deceased pocket wall thereby exposing tooth surface which provides the visibility and access ability that are essential for the complete removal of irritating surface deposits and thorough smoothening of the roots.

.Inflammatory changes in the soft tissue surrounding an implant is diagnosed as a) peri implant gingivitis b) peri implantitis c) peri- implant mucositis d) Peri-implantosis

A “root replica” or a “root form” implant is a titanium fixture inserted in the jaw to act as a tooth root and anchors a restoration (single crown, bridge, or denture). The final restoration looks, feels, & functions like a natural tooth.

1. Bone loss associated with trauma from occlusion is; A. notching B. vertical C. horizontal D. cystic

Orban and Glickman et al (1968): truma from occlusion is defined as when occlusal forces exceed the adaptive capacity of the periodontal tissues , the tissue injury results. This resultant injury is termed as trauma from occlusion.

A periodontal pocket of 6mm deep lying coronal to the junctional epithelium is A. Infrabony pocket B. Periodontal pocket C. True pocket D. Pseudo pocket

Pocket depth is the distance between gingival margin to the base of the pocket (or coronal end of junctional epithelium). Pocket depth of 6mm means distance between gingival margin and base of sulcus is 6mm

1. Gingival swelling most commonly A. Causes increase in stippling of attached gingiva B. Results from inflammatory oedema C. Associated with gingival recession D. Results from tetracycline therapy

The many types of gingival enlargement can be classified according to aetiologic factors and pathologic changes as follows:

1. Most common periodontal disease is A. Gingivitis B. Periodontitis C. Gingival hypertrophy D. Juvenile periodontitis

Gingivitis is the most common form of gingival disease. - Only some cases of gingivitis progress to periodontitis - About 90% of population is affected by gingivitis by the time they cross their puberty
