Abstract:
Background: Morphological structure of dental enamel-cement border of the 7th tooth is of great interest to many dentists with various different meanings. Study of the border of the 7th tooth allows the visual description of the morphological structure of this region. Objectives: To highlight the structure of dental enamel-cement border as well as its application in the endodontic treatment. Subjects and methods: The team used screening electronic microscopy to investigate the morphology and structure of twenty, second molar of adults who are between 18 and 35 year old. These teeth were extracted due to dental correction or caries (on chewing face). The study was conducted on both non-demineralized and demineralized teeth. Results: There are 3 kinds of connection in the enamel-cement border area of second molar: cement covering enamel, enamel-mineralized peridental ligament there is a gap between enamel and cement without exposing dentine. The kind of cement covering enamel connection is characteristic for dental interior face. The kind of enamel-mineralized peridental ligament is characteristic for the proximal, distal and middle dental face, the kind of enamel and cement without exposing dentine is characteristic for external face. Conclusion: Research conducted on only a small amount of tooth No. 7, further studies should be carried out on other teeth to have a more accurate description. \r\n', u'\r\n', u'
