Document Content and Description Below

INBDE - Mastery - ENDO Dental trauma seen in children ages one to three is commonly caused by or attributed to - ✔✔underdeveloped motor coordination skills. Which of the following is the recomm... ended treatment for a posterior primary tooth with a draining abscess, no mobility, no radiographic furcal bone loss, and roots that are completely intact? - ✔✔Pulpectomy When is pulpectomy indicated in primary teeth? - ✔✔Pulpectomy is indicated for cases in which there is no tooth mobility but the infection might already have reached the pulp. ___________ is indicated for primary teeth having suffered accidental pulp exposure or a bacterial attack that only affects the coronal portion of the pulp. - ✔✔pulpotomy T/F - indirect pulp capping is indicated for primary teeth - ✔✔FALSE - Indirect pulp capping is not indicated for primary teeth but is used for permanent teeth with a cavity or caries approximating the pulp. Which of the following describes the best management strategy for an instrument that is separated in the apical third after cleaning and shaping have occurred? - ✔✔Do not attempt to remove and proceed then to obturation. If an instrument separates at the filling or obturation stage, the instrument does not require removal, because the etiology of the problem has already been resolved through cleaning and shaping of the canals. A marked reduction in the size of a periapical radiolucency can be expected by which of the following after a root canal procedure is completed? - ✔✔one year Periapical bone regeneration usually occurs at a rate of about 1.2 mm² per month, gradually reducing the size of the periapical lesion. When instrumenting the mesial root of tooth #19, which canal surface is the most likely to become strip-perforated? - ✔✔Distal The mesial surface of the distal root and the distal surface of the mesial root in the mandibular first molar have a root concavity, making the dentin walls very thin. Overenthusiastic root canal instrumentation (overcutting) can lead to strip perforations in these areas and should be avoided. Which of the following steps should be taken initially to ensure the successful replantation of a maxillary central incisor in a 13-year-old patient? - ✔✔Reposition and splinting only. tooth should be splinted until it is stable and then necessary treatments can be done. A patient presents with yellow discoloration of tooth #8 a few months after a reported fall that injured the tooth. Which of the following proceses is likely responsible for the post-traumatic discoloration of tooth #8? - ✔✔Calicific Metamorphosis What is the name of a process where it is common reason teeth appear yellow after trauma occurs and is recognized clinically as early as three months following injury. - ✔✔calcific metamorphosis Internal bleaching of an inadequately obturated tooth can lead to - ✔✔external cervical root resorption symptomatic apical peiodontitis T/F - resin root canal sealers typically demonstrate antimicrobial properties - ✔✔FALSE --- they do not disinfect the canals Root canal sealers can: - ✔✔fill voids between gutta-percha points [Show More]
