Systemic corticosteroid therapy. Chronic renal failure. Prolonged NSAID therapy. Malabsorption syndrome. A 7 year old patient is missing tooth 5.5 and tooth 7.5. Space maintainers were not placed. A current mixed dentition analysis yields the following data: R L -5mm -3mm (maxilla) -3mm -4.5mm (mandible) The actual space loss assuming there was no asymmetry in tooth sizes is 8mm in the maxilla. 2mm in the maxilla. 7.5mm in the mandible. 4.5mm in the mandible. 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 tothe 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 denture and reduce the posterior extension of the mandibular denture to eliminate interferences.

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.
