When restoring a class II preparation, the first increment of material should be placed in the: Depth of proximal box Material that can be used as either cement or restorative material in a class V lesion Glass Ionomer When placing a composite restoration, the composite is often placed in layers to: Reduce the effect of polymerization shrinkage When the tooth exposed to stimulus such as caries, cavity preparation, or trauma it lays down: Reparative/ tertiary dentin Which type of adhesive would typically be used to temporarily cement a provisional crown or bridge? Zinc Oxide Eugenol The material that is utilized for a pulp cap is called: Calcium hydroxide

What molars have a distal cusp? Mandibular 1st molars Where can the cusp of Carabelli be found? Maxillary 1st molars What should be even heights when restoring teeth? Marginal ridges Incomplete closure of the lobes coming together Fissure Runs from cusp tip to the central groove on the occlusal surface Triangular ridge Convexity running from the distobuccal cusp to the mesiolingual cusp Oblique Ridge

Excess mercury is brought to the surface of the amalgam when during... condensation/ polishing An unfilled sealant material will self adjust and a filled sealant material will need adjusted True A small elevation on the lingual surface of a maxillary central incisor: Cingulum The largest embrasure, best suited for wedge placement is the: Lingual embrasure Which cement is the best choice when an obtundent effect is desired? Zinc Oxide Eugenol` The metal alloy used in amalgam is primarily composed of: Silver

The pulp is capable of what sensation? pain The cells that produce enamel are called: Ameloblasts A dry angle should be placed over: Stensons duct A three-cusp type mandibular second premolar often has: A "Y" shaped groove pattern An oblique ridge can be found on: Maxillary 1st molars A 5th cusp is commonly found on Maxillary/Mandibular 1st molars

2 roots 1 buccal, 1 lingual Between the tooth and bonding agent: Mechanical retention Have the ability to soothe the pulp sensitivity: Obtundents EFDA's renew licenses every? March 31st - odd years! 1st in removing the dental dam remove the ligation (dam or floss) What would be the best in office fluoride treatment for a 4 year old patient? Fluoride varnish (topical fluoride)

Corrosion: Break down of amalgam by acids Transverse ridge: The union of two triangular ridges (facial/lingual) that produces one ridge across the occlusal surface Anatomical crown: Portion of the tooth that is covered with enamel Clinical crown: That portion of the tooth that is visible in the oral cavity The area where the roots divide Furcation Contact areas serve two purposes Stabilize dental arch, to keep food from packing between the teeth.

Consist of primarily of blood vessels and nerves; vascular; deep to the Dentin A triangular ridge cusp ridge that descends from the cusp tips toward the central part of occlusal table The six advantages of the rubber dam Dry, clean and visible field of operation. Protection of patient and operator. Economic factors. Improved properties of dental materials. Retraction of soft tissues. Application of medicaments. Reinforcers Bases used to protect the pulp from pressures exerted on it during amalgam placement (condensing) Stimulator Calcium hydroxide (dycal) Insulators

Also referred to as bases (cements used in thick layers) and are placed to insulate the pulp from thermal irritation. The combination of tin and mercury results in: Gamma phase 2 Creep The slow change in dimensions of the amalgam due to prolonged exposure to stress. Dental Amalgam Alloy An alloy of silver, copper, tin, and zinc powder particles or as a compressed pellet. Two types of alloy particles lathe cut and spherical What would happen if amalgam was contaminated with moisture? Bubbles of hydrogen from the water would cause delayed expansion.

The band should be extended _________ gingival to the gingival margin of the cavity. 0.5mm to 1.5mm Class I molar relationship mesiobuccal cusp of the maxillary first molar is positioned in the buccal groove of the first molar A wedge is used to Prevent overhang/ to adapt the band to the cervical region of the tooth Class II molar relationship buccal groove of the mandibular first permanent molar is distal to the mesiobuccal cusp of the maxillary first permanent molar by at least the width of a premolar Overjet Horizontal projection of upper teeth over the lower.

Overbite Increased vertical overlap of the maxillary incisors Sealants are indicated for which areas? deep pits and fissures Type of material that bonds directly to the tooth? Glass Ionomer Why were sealants created? to provide a physical layer over occlusal fissures to prevent plaque, bacteria, and food debris from collecting in the grooves. Most sealant material is made of what? BIS-GMA for strength If saliva contaminates the tooth during the placement of a sealant, one should: re-etch the tooth for 10 seconds.

A ligual pit is most commonly found on what teeth #'s? #7/ On a maxillary first premolar what is the groove that separates the buccal and lingual cusps? Central groove Interproximal spaces between teeth gingival papillae A pinpoint depression where two or more grooves meet? pit A cavity prep the includes the mesial incisal angle of a maxillary central incisor is a? Class IV

Touching together of the upper and lower teeth when jaws are closed Centric occlusion Protrusive movement The straight forward movement of the mandible cross bite When the mandibular teeth are outside (facial/ buccal) of the maxillary teeth Working cusps Upper lingual cusps and lower buccal cusps Non working cusps Upper buccal cusps and lower lingual cusps The part of the clamp that is expanded to fit over the tooth Jaw

What can be used as a sedative dressing under a restoration ZOE
