How many molars are present in the mandibular arch? 6 The permanent mandibular second molar differs from the permanent mandibular first molar by number of? Cusps Which is not found on the occlusal surface of a mandibular molar? Cingulum A cusp of carabelli is located on a maxillary first molar of the? Mesiolingual cusp 3 round protuberances Mamelons What is found on both posterior and anterior teeth? Marginal ridges A ligual pit is most commonly found on what teeth #'s? 7 and 10 What molar is likely to have 3 buccal cusps? Mandibular first The label Mesiobucco-occlusal is appropriate for? Point Angle of a posterior tooth

On a maxillary first premolar what is the groove that sperates the buccal and lingual cusps? Central groove The molar with a Y,H, or U pattern Mandibular second premolar A facial and lingual triangular ridge join to form? Transverse ridge Cusps for a mandibular first molar mesiolingual, mesiofacial, distolingual, distofacial, distal Major difference between first and second molars? 1st molars has 5 cusps, 2nd molars have 4 cusps Which is true of oblique ridges? Only Maxillary molars have Oblique ridges Facial surfaces of teeth include what? Labial and Buccal surfaces Elevated crests of enamel that form mesial and distal margins of the occlusal surface Marginal ridges The bulk of a tooth is made up of Dentin Interproximal spaces between teeth Gingival papillae

Mesial and distal marginal ridges are found on Both Posterior and Anterior teeth The distal triangular fossa of the maxillary first molar is separated from the central fossa by the? Oblique ridge A pinpoint depression where two or more grooves meet? Pit V-shaped spaces between proximal surfaces of two adjoining teeth Embrasure A cavity prep the includes the mesial incisal angle of a maxillary central incisor is a? Class IV Overbite Vertical overlap of maxillary incisors Centric occlusion Touching together of the upper and lower teeth when jaws are closed Overjet Horizontal space between upper and lower incisors Excursive movements Movement of jaw from left to right Protrusive movements Thrusting lower jaw forward

Crossbite Mandibular teeth are facial to their maxillary counterparts Working cusps Lingual of upper; Buccal of lower Non-working cusps Buccal of upper; Lingual of lower Walls of a molar pulpal floor,buccal,distal,lingual,mesial Features of the occlusal surface of a permanent maxillary molar include.. distomarginal ridge, mesiomarginal ridge, oblique ridge, distomarginal ridge, cusp of caribelli Structure that covers the anatomical crown of a tooth Enamel The maxillary first premolar differs from the maxillary second premolar in that the maxillary first premolar has: 2 roots, one buccal and one lingual The relationship between the working end of the instrument and the tooth surface Adaptation Carious lesions are least likely to occur on Cusp tips Instruments used to place amalgams/composite resins into preps

Compactors The radicular pulp continues with the tissues of the periapical area via the Apical Foramen The part of the clamp that is expanded to fit over the tooth Jaw Strength and wear rates of a composite are critical to consider when selecting a material for placement of what class for stength class I,II, and III The most versitile composite Hybrid Prior to placement of a class II Both a wedge and matrix band are needed Restoring a class II with too large an increment of composite at once can cause post-op sensitivity due to Undercurring, shrinkage and improper condensing Everything should be dispensed according to what? The Manufacturer's Instructions

Curing lights should be tested weekly to ensure that the bulb is intense enough to cure through the composite Total Etch etching the enamel and all involved dentin of the prep During composite finishing procedure a green stone is used to remove areas of excess composite when necessary Sequence for polishing composite white stone, brown point, green point, white point, polishing paste Mechanical retention between tooth and bonding agent Chemical retention between bonding agent and composite Composites can be self cured, light cured and dual cured Post-op sensitivity with posterior restorations can result from hyper occlusion, over etching and operative trauma

Which area of a class V amalgam is carved free hand the central portion During a class II composite procedure the ring of a sectional matrix is placed after placing the wedge Which situation would cause a composite restoration to fail? an internal void, moisture contamination, and improper light curing When polishing composite its best to go from Course to Fine Acid etch technique utilizes 35% phosphoric acid The most critical difference that distinguishes composite material is the particle size Direct supervision is defined as the dentist remaining where while treatment is being preformed in the facility EFDAs are not permitted to..

Do anything Final! Gingival retraction cord soaked in epinephrine can cause Tachycardia acetone, alcohol and water Carrying agents Bonding is never used as an lubricant To prevent post-op sensitivity the EFDA should apply what as the first increment in a class II prep flowable The sequence for finishing and polishing a composite finishing bur, coarse, medium, fine discs, polishing paste Primer must be dispensed immediately to prevent evaporation Coronal polishing Removing plaque and stains from coronal surfaces of teeth

Polishing does NOT improve the uptake of professionally applied FL2 therefore polishing is before FL2 application NOT NECESSARY Exogenous stains are caused by environmental sources and are classified in to subdivisions including: Intrinsic and Extrinsic stains Which is an example of an endodgenous stain? an excessive amount of fluoride during development of the tooth What polishing paste is recommended for use on filled hybrid composite restoration? Aluminum oxide An Oral Prophy includes Removal of calculus and debris Extrinsic/Exogenous stain A stain that may be removed from the surface of the teeth(food and drink) Intrinsic/Endogenous stain A stain that cannot be removed for the surface of the teeth(smoking,tobacco,dental amalgam) Which is the most common technique for stain removal? Rubber cup polishing

What damage can result for using the prophy angle at a high speed? it can cause frictional heat that can burn the gingiva and damage the tooth HEIGHT OF CONTOUR on the facial surface of a posterior tooth is at the Cervical third Slow flow or movement of amalgam Creep Carious lesions located on the proximal surfaces of molars and premolars class II Carious lesions located on the proximal surfaces of central and lateral incisors class III Cavosurface margins should be check with an explorer A wedge is used for what class of amalgam restoration? class II Where should you begin restoring a class II prep?
