The definition of general supervision allows the dentist to be out of the office while a procedure is being performed. 2. The duties and settings of all dental assisting functions is a matter of state law. The dentist is required to know the supervision level for all categories of dental assistance. The required supervision level by a dentist for an RDAEF is direct supervision. 3. In order to renew a dental related license in the state of California, the operator must complete mandatory continuing education each renewal. Currently, the RDAEF must complete three hours of dental practice act continuing education to renew the license every two years. 4. According to the dental practice act, tape recorded courses, home study materials, video courses and computer courses are considered correspondence courses and will be accepted for credit up to, but not exceeding, 25% of the licensees total required units needed for renewal. 5. An unlicensed dental assistant in California is allowed to perform placing, finishing or removing permanent restorations under general supervision. 6. A registered dental assistant or a registered dental assistant in extended functions who holds a permit as an orthodontic assistant shall not be required to complete additional continuing education requirements beyond those required for the license renewal in order to also renew the permit. 7. A registered dental assistant is allowed to dry endodontically treated canals. 8. An unlicensed dental assistant is allowed to obtain a face bow transfer and a bite registration. 9. A registered dental assistant is allowed to Polish an existing amalgam restoration. 10. A registered dental assistant is allowed to place, adjust, and finish a direct restoration. 11. The universal retainer is also known as the sectional matrix retainer. 12. A type of matrix band that encircles the entire tooth Without the use of a traditional retainer is also called a circumferential matrix band. 13. A type of matrix that fits only on one proximal surface at a time where a mesial or a distal wall is involved in the preparation is referred to as a sectional matrix and does not require a traditional retainer. 14. The principal purpose for contouring a tofflemire matrix band prior to placement is to ensure that the final restoration will have a proper contact with the adjacent tooth. 15. An improperly contoured matrix band will have little or no effect on the integrity of the contact point. 16. The dentist has prepared a class 3 restoration on a maxillary central incisor. The appropriate type of matrix system to use on a Class 3 restoration is a mylar matrix system. 17. During the process of assembling a tofflemire matrix band, the two ends of the band are brought together to form a circle. The edges of the circle are called the circumference. In reviewing the size of the circumference on either side of the band, the operator notices that the circumference on one side is smaller than the other. The smaller circumference of the band is therefore placed toward the gingiva. 18. Following completion of the preparation of a tooth for a restoration, a fairly large portion of the tooth is missing. In this case scenario the matrix system that will provide the best support while restoring the tooth is the universal tough Tofflemire system. 19. The principal reason why a stainless steel matrix band should not be used on an anterior composite restoration is to prevent scratching the resin itself and to ensure the stainless steel band can interfere with the setting of the resins. 20. The only licensed clinical chairside assistant who would ever be asked to document every preparation, restoration, crown, and bridge we provide to that patient. 21. The cavity classification that involves the mesial or distal surface of incisors and canines only is a Class 2. 22. Occlusion, is the term used to best describe the relationship of the mandible and the maxillary teeth when the teeth are closed together. 23. Retrusion refers to the position of the mandible relative to the maxilla. 24. Blacks classification of caries is designed to identify the location of decay and the best method for accessing the tooth during a restoration procedure. A Class 2 involves the occlusal surface of a premolar or molar. 25. A class one involves the pit and fissures of the occlusal surface of molars and premolars and may also involve a buckle or lingual pit of a molar or a lingual pit of a maxillary incisor. 26. The classification that best identifies the presence of caries at the gingival third of the facial or lingual surface of a tooth is a class 5. 27. As it relates to resin or composite based restorative materials, the amount of thermal expansion is important to understand and be aware it occurs. 28. The term adhesion refers to a method of mechanical retention. 29. The term that best describes whether a material is thick or thin is called viscosity. 30. One of the unintended consequences of dental restorations when using a resin or composite based material is how well the material adapts to the restoration, if the operator places the material effectively and efficiently. A poorly placed restoration may cause a fracture within the restoration. Expansion and contraction of the restorative material may also be a factor in causing micro leakage. 31. The most commonly used etchant or conditioner for tooth bonding is hydrochloric acid in concentrations ranging from 10% to 38%. 32. When a resin bonding agent hardens, it creates projections that lock into the tooth, creating a mechanical bond. The resin bonding agent will then form a chemical bond to other resins placed over it, such as composite resin. 33. When acid etching for bonding, it is preferable to have a high surface energy and a high angle of contact. 34. The smear layer interferes with the formation of a bond to dentin and needs to be removed prior to the restorative process being completed. 35. The purpose of performing a gingival retraction procedure is to capture the details necessary following the preparation of a tooth for an indirect restoration. 36. Gingival retraction is intended to manage bleeding and saliva That results from a final impression procedure. 37. Gingival retraction cord displaces gingival tissue mechanically. Non-impregnated retraction cord does not contain a chemical agent and retracts the tissues only by force. 38. Chemically treated gingival retraction cord contains and astringent that helps control bleeding. 39. Hemodent gingival retraction cord contains 5% to 10% of aluminum chloride. Aluminum chloride is a mineral astringent that does not produce and desirable cardiovascular effects. 40. A hemostatic solution can be dispensed onto a small cotton pellet and massaged around the gentle tissue following the packing of cord. 41. When a composite resin is polymerized, a small layer of uncured material will remain called the hybrid layer. 42. The anatomical structure of each tooth dictates its ability to withstand certain types of force. The three basic types of force are compressive force, tensile force, and shearing force. Of the three terms, the one used to best define when force is applied to squeeze an object is compressive force. 43. Of the three basic types of force that can be placed on a tooth, The term used to best define this force that is applied when two surfaces slide against each other in opposite directions. This type of force is called shearing force. 44. The primary purpose of dentinal bonding is to provide sealed margins. 45. Altering the set ratios of a material for any purpose we\'ll have little significance in how well the material performs. 46. One of the primary advantages of using a glass ionomer compared to a composite restoration is that it has been shown to release fluoride thereby arresting the progression of decay. 47. There are four main types of composite currently used in contemporary dentistry for restorative purposes. They are hybrid, microfilm, nanofilm, and nanohybrid. Of the four types of composites, the one that demonstrates a high level of weakness and should not be used in stress bearing tooth surfaces is a microfilm material. 48. The most effective material to use in the prevention of decay, especially in children, is glass ionomer.
