Long-acting forms of nitroglycerin are used to prevent angina from happening. Short-acting nitroglycerin, administered either as a sublingual tablet or spray, can complement anti-anginal therapy as part of optimal medical therapy in patients with refractory and recurrent angina either with or without myocardial revascularization, and is most commonly used to provide rapid therapeutic relief of acute recurrent angina attacks. Which one of the following is an established clinical use of morphine? A. Management of generalized anxiety disorder B. Relief of pain associated with biliary colic C. Pulmonary congestion D. Treatment of cough E. Suppression of the ethanol withdrawal syndrome - ANSWER C..pulmonary congestion...morphine is used in pulmonary congestion ,in part because of its sedative (calming) and analgesic effects and also because of its vasodilating actions,which result in favourable hemodyanamics in terms of cardiac and pulmonary function. which drug act as epileptic and neural pain inhibitor - ANSWER carbamazepine and gabapentin x ray for subcondylar fracture x ray for disc of tmj - ANSWER 1-subcondylarfracture- ct, pano disk -hard tissue evaluation-pano softtissue evaluation-arthrography Patient has an all veneer on incisal edge, small piece of porcelain came off and wants you to fix the chip only, what is the sequence of events? - ANSWER The fractured porcelain veneer is air-abrade using aluminum oxide to increase micromechanical retention with the abrasion unit------- etchant-----silane----- Bonding resin is placed on the restoration ------Composite material----The completed restoration and polish. cavernous sinus thrombosis. This complication involves which of the following cranial nerves? A. IV, V, VII, IX B. II, III, IV, X C. IV, VI, VII, VIII D. III, IV, V, VI - ANSWER ans-d A cyst situated posterior to nasopalatine duct cyst - ANSWER median palatal cyst Histologically blue cell tumours such as lymphoma& Ewing sarcoma is differentiated by? - ANSWER ewing sarcoma contains glycogen(shafers page 165) 28. To drain submandibular abscess: a. lntraorally through the mylohyoid muscles b. Extraorally at the lower border of the mandible. c. Extraorally under the chin. d. Extraorally at the most purulent site. 66. Patient suffering from a submandibular gland abscess. Dentist made a stab incision and is fixing a rubber drain to evacuate the pus. The drain is sutured to: a. Intra-oral b. From angle of the mandible c. Between myloid muscle d. All the above 64. For continous evacuation of pus in a mandibular space infection, the incision and drainage will be done in: a. The most necrotic part of the abscess b. The most bottom of the abscess c. Intra oral d. All the above - ANSWER 28-d,66-b,64-b The beat grasp to use when holding an instrument to be sharpened is - ANSWER Grasp the instrument -Palm gasp -Stabilize hand on countertop -Stabilize instrument handle with your thumb Autoimmune conditions with higher incidence of periodontal diseases - ANSWER Crest syndrome,crohns disease, rheumatoid & lupus erythematous,multiple sclerosis metabolic deficiency diseases which effect periodontal diseases? - ANSWER diabetes,Hypophosphatasia MA 10 exposure 1 second then if u do exposure 0.5 then whats MA? - ANSWER So if 10*1= 10mas So if time is 0.5 sec then ma u have to inc 20 to make 10 mas So 20*0.5 = 10 mas Which drug u should give carefully give to pt with dysplastic muscle disease - ANSWER increase water powder ratio leads to decrease setting expansion and increased strength?t/f - ANSWER increase water powder ratio lead to dec setting expansion, decrease strength and increase setting time overtrituration lead to inc stregth , dec setting time and dec expansion Inorganic component of calculus is crystalline ,which is more common in mandibular anterior region 1) hydroxyapatite 2) brushite - ANSWER Md anterior - brushite posterior- magnesium whitlock if increase distance of the tube from receptor by 2- intensity is---? and the exposure time is ----? - ANSWER ans-intensity will be decreased by 1/4 times so exposure time has to be increased by 4 times (mA) × length of exposure time (S) = mAs • Increasing mAs = increase in primary signal intensity • Decreasing mAs = decrease in the primary signal intensity Source image distance, the "Inverse Square Law" has an inverse relationship with the intensity of an x-ray beam: Old mAs Setting × New SID² = New mAs Setting Old SID² • Increasing the distance = decreasing in the beam intensity at the receptor • Decreasing the distance = increasing the beam intensity at the receptor Plaque accumulation has a direct effect on which of the following? A. The level of materia alba B. The severity of gingivitis C. The accumulation of calculus D. The severity of periodontitis - ANSWER b-the quantity of the plaque is related to the severity of gingivitis. BUT the quality is related to severity of periodontitis an increase in radiographic density is most likely caused by a decrease in - ANSWER e-As SID increases, exposure rate decreases and radiographic density viseversa Which of the following compounds is responsible for the photoinitiation step of light-cured sealants? Bisphenol A Benzoyl peroxide Fumed silica Fluoride Camphorquionone - ANSWER E is the right answer ! Camphorquinone is used as a photoinitiator and visible light or an argon laser is used as the activator in light-cure sealants. One of the most important requirements of a pits and fissure sealant is that it should prevent leakage at its periphery and give an adequate working time. It has been shown that the adherence of pits and fissure sealants and working time is significantly better in light-cured sealants as compared to chemical cure sealants. Benzoyl peroxide is incorporated as a component in auto-curing/self-curing sealants. An eye that has chronic exposure to visible light curing units will sustain the most damage to which of the following structures? Retina Lens Iris Cornea Ciliary muscle - ANSWER Correct answer is A !
