2. Discuss two differences you discovered in the location of the CEJs

Question 2. Discuss two differences you discovered in the location of the CEJson the maxillary anterior teeth versus the maxillary posterior teeth.In Maxillary molars, Cervix of crown tapers more to lingual.Maxillary anterior teeth have a greater curvature of the cementoenamel junction (CEJ), and the mesial curvature of a tooth is greater that the distal. Posterior teeth have flatter CEJ curvatures on the interproximal aspects of the teeth than the anteriors.On anterior teeth the curvature is v-shaped towards the incisal surface and more prominent on the mesial suface of incisors, especially the maxillary central incisor (#8).Facial and lingual contours of the CEJ on anterior (#8) and premolar(#5) teeth are convex and the CEJ is much straigter on molar(#3).3. Discuss two differences you discovered in the location of the CEJs on the mandibular anterior teeth versus the mandibular posterior teeth.In Mandibular molars, Cervix of crown tapers less to lingual.Medibular anterior teeth also have a greater curvature of the cementoenamel junction (CEJ) than posterior teeth, and the mesial curvature of a tooth is greater that the distal.Proximal curvature of the CEJ is more pronounced on anterior than on posterior teeth.Mandibular anterior teeth are semicircular and mandibular posterior teeth are very less curvature and mandibular anterior teeth are smooth and regular but mandibular posterior teeth are not smooth and irregular.(Curvature of the CEJ is greatest on the anterior teeth due to the narrow profile of these teeth.The height of the distal aspect’s curvature on the anteriors is usually 1 mm less than that of the mesial aspect. Posterior teeth have flatter CEJ curvatures on the interproximal aspects of the teeth than the anteriors.)4. Discuss two challenges you experienced when attempting to locate the CEJ on the maxillary anterior teeth versus the maxillary posterior teeth.The maxillary anterior teeth have a thick buccal cuspid and a large, open pulp chamber. As a result, locating the CEJ on the maxillary anterior teeth can be a challenge.The maxillary teeth are located anterior to the mandibular teeth, and locating the CEJ on the maxillary teeth is a challenge. In general, the maxillary incisors are located higher than the mandibular incisors, and the CEJ on the maxillary incisors is therefore located further away from the cervical line than the CEJ.5. Discuss two challenges you experienced when attempting to locate the CEJ on the mandibular anterior teeth versus the mandibular posterior teeth.The mandibular lateral incisors appears twisted distally at the CEJ.The first challenge is that the mandibular teeth are located beneath the maxillary teeth, and the location of CEJ on the mandibular teeth is often obscured by the enamel at the line angle. The CEJ on the mandibular posterior teeth is located behind the incisal edges, which enables the maxillary posterior teeth to be more easily located. The second challenge is that the mandibular anterior teeth are very small, which limits the direct visual access to the CEJ.6. Discuss two modifications you would make to locate the CEJ on all the teeth you have chosen if you were to apply this assignment to a live patient.(Extend the exploer going towards the distal and when coming towards the mesial come higher up on my fulcrum to have a better grip and adaptation.Adapt instrument to the lingual inclination of mandibular posterior teeth by slightly aligning instrument shank toward the lingual surface.)  from the this information #2 and #3 can you please answer #5 and #6 ?    Health Science Science Nursing NUTRITION 4340 Share QuestionEmailCopy link Comments (0)
