Oblique ridge - ANSWER Ridges only on occlusal of max molars 31. Axial wall - ANSWER parallel to the long axis of the tooth, adjacent to pulp 32. Teeth with 2 buccal grooves - ANSWER Mans first molars 33. Insulators - ANSWER Insulate pulp from thermal irritation: ZOE ZIMC PHOSPHATE 34. zinc phosphate - ANSWER Insulator and reinforcer. Main ingredient to phosphoric acid. Chemically irritation to pulp 35. Zinc Polyacrylic Cement - ANSWER Kind to pulp 36. OBTUNDENTS - ANSWER Soothe sensitive pulp, ZOE IRM 37. STIMULATORS - ANSWER Mildly irritating to pulp form reparative dentin, calcium hydroxide 38. Minimal depth restoration - ANSWER 0.5mm to 1.5mm 39. not used under composites - ANSWER Cavity varnish and zoe 40. Increases strength of amalgam - ANSWER Copper 41.

Marks left on articulating papers should appear as - ANSWER Dots 45. Bases and liners - ANSWER May be used as sealers ,reinforcers insulators 46. obtudents and pulp stimulators 47. Sealers - ANSWER Function to seal off the cavity preparation used in a thin layers also known as a liner 48. Sealer - ANSWER Known as a liner 49. Sealer - ANSWER Seal off openings of the cut dentinal tubules and prevent chemical irritants from reaching the pulp 50. Sealer - ANSWER Seal off the microscopic space between the tooth surface and restoration while reducing the leakage of fluid around the restoration 51. Sealer - ANSWER Cannot provide thermal insulation because they are too thin 52. Cavity Varnishes - ANSWER Are also known as sealers 53. cavity varnish - ANSWER Composed of natural or synthetic residence dissolved in an organic volatile solvent 54. Varnishes - ANSWER Was placed under all amalgam restorations by many practitioners but it is not used as commonly now 55. Varnish - ANSWER Should not be used under resins as the solvent in the varnish may react with or soften the resin and the monomer of the resin may dissolve in the varnish 56. Resin cements - ANSWER Used as liners in preparation more commonly today then varnishes 57. Resin cements - ANSWER Do not bond as well to deep Dentin as they do more superficial Dentin, they can cause an inflammatory response from the pulp or tissues for these reasons they are not used as the direct pulp capping agents 58. Copalite - ANSWER Cavity varnish that is a sealer used under amalgam 59. Reinforcers - ANSWER Are bases used to protect a pulp from the pressure exerted on it during amalgam placement/condensation 60. Reinforcers - ANSWER Can be an insulator and in reinforcer at the same time 61. Reinforcers - ANSWER Can be any material that is placed in a relatively thick layer between the restorative material and the Dentin and may be referred as to a base regardless of the purpose it serves 62. Insulators - ANSWER Also referred to as bases and our place to insulate the pump from thermal irritation 63. Zinc Oxide Eugenol (ZOE) - ANSWER Used as an insulating base and reinforcer this is a cement that can be used as a base under amalgam restoration or as a temporary restoration 64. zinc phosphate cement - ANSWER Is also used as an insulator and reinforcer main ingredient of liquid is a phosphoric acid which can be chemically irritating to the pulp. Should be protected by using a varnish or non-irritating liner between this cement and Dentin. 65. Zinc polyacrylic cements - ANSWER Also called carboxylate and polycarboxylate cement are also used as insulators and reinforcers of a liquid solution is a viscous mixture of poly acrylic acid 40% in water 66. Obtundents - ANSWER Have the ability to soothe The sensitive pulp or reduce the irritability of the pulp in a situation in which a tooth has undergone some trauma that caused pulpitis and pain ,these will decrease the reaction and reduce the pain. 67.

Pulp stimulators - ANSWER Natural protector an insulator for the pulp. 69. Stimulators - ANSWER Used in the deep cavity preparations where the remaining layer of Dentin over the Pulp is very thin in order to stimulate a thickening of the Dentin layer 70. Pulp stimulators - ANSWER Have a mildly irritating affect on the pulp that has a beneficial effect it stimulates the pulp to form a layer of secondary repaired of Dentin to protect itself from the irritant 71.
