The setting of a zinc-phosphate cement can best be retarded by decreasing the particle size. increasing the concentration of water in the liquid. increasing the rate of addition of the powder to the liquid. cooling the glass mixing slab. What is the most likely diagnosis of a white lesion on the retromolar pad opposing a non -functional molar? Alveolar ridge keratosis. Candidiasis. Lichen planus. Squamous cell carcinoma. Upon examination of an edentulous patient, it is observed that the tuberosities contact the retromolar pads at the correct occlusal vertical dimension. The treatment of choice is to reduce the retromolar pads surgically to provide the necessary clearance. reduce the tuberosities surgically to provide the necessary clearance. construct new dentures at an increased occlusal vertical dimension to gain the necessary clearance. proceed with construction of the dentu re and reduce the posterior extension of the mandibular denture to eliminate interferences. A hinge axis facebow records Bennett angle. centric relation. lateral condylar inclination. horizontal condylar inclination. opening and closing axis of the mandible. The most important objective of occlusal adjustment of a natural dentition is to prevent temporomandibular joint syndrome. increase the shearing action in mastication. improve oral hygiene by preventing food impaction. achieve a more favorable direction and distribution of forces of occlusion. Which of the following is essential for successful periodontal treatment? Scaling. Final evaluation and maintenance on a one- year recall. Periodontal flap surgery. Elimination of local etiologic factors. A hinge axis facebow records Bennett angle. centric relation. lateral condylar inclination. horizontal condylar inclination. opening and closing axis of the mandible. The predominant type of movement produced by a finger spring on a removable appliance is torque. tipping. rotation. translation. Which condition has NOT been associated with Candida albicans infection? Median rhomboid glossitis. Angular cheilitis. Denture stomatitis. Aphthous ulcerations. Oral hairy leukoplakia. If a complete mandibular denture causes a burning sensation in the premolar region, this is due to the denture exerting pressure in/on the fibres of the buccinator muscle. lingual branch of the mandibular division of the trigeminal nerve. underlying bone. mental branch of the inferior alveolar nerve. buccal frenum area. Which of the following microorganisms are most frequently found in infected root canals? Streptococcus viridans. Staphylococcus aureus. Lactobacilli. Enterococci. Staphylococcus albus.

The bond between porcelain and metal in a ceramometal (porcelain bonded to metal) crown is chemical. mechanical. equally chemical and mechanical. neither chemical nor mechanical. Soft tissue pockets CANNOT be reduced by occlusal adjustment. scaling and root planing (debridement). open flap curettage. guided tissue regeneration. When designing a removable partial denture, changing the tilt of the cast on the surveyor alters the path of insertion of the planned removable partial denture. the position of the survey line on the cast. the undercut and non-undercut areas. the direction of forces applied to the partial denture. Needle deflection increases as depth of injection increases. needle length increases. needle gauge decreases. All of the above.
