High impact information on Tooth Cervix

  • In the alveolar bone of the maxilla, the distance between the cementoenamel junction and the alveolar bone crest was larger in iNOS KO compared to WT mice from 6 to 14 weeks of age, indicating a developmental effect of iNOS in oral tissues [1].
  • RESULTS: Resorption involved the coronal root at the cementoenamel junction (CEJ) in 95% of teeth and focal resorption of intact enamel was observed in 14% of teeth [2].
  • METHODS: To understand the interactions among the retainer design factors, three values of retainer thicknesses (1.2, 0.8 and 0.4mm), heights (100, 75 and 50% of the distance from 2mm above the CEJ to the occlusal surface) and angle of the axial surface extensions (150, 180 and 210 degrees ) were selected as the design parameters [3].
  • Post- and-core restorations were made on single-rooted human maxillary premolars from which the coronal sections were removed at the level of the proximal cemento-enamel junction (CEJ) [4].
  • Each inter-dental site that was readable was scored as one for the following categories: not available (NA); no bone loss (NBL)- the CEJ-ABC was < or =2 mm; questionable bone loss (QBL): the distance from the CEJ-ABC was >2 and <3 mm; and definite bone loss (DBL): the distance from the CEJ to ABC was > or =3 mm [5].

Anatomical context of Tooth Cervix

  • For the fluoride uptake and artificial caries test, standardized restorations were placed along the cementoenamel junction of extracted human molars [6].
  • Distances in mm were obtained from the cemento-enamel junction (CEJ) to the probe tip, to the base of the crevice/pocket, and to the most coronal connective tissue attachment [7].
  • By the use of a high-definition 3-D microscope, it appeared that Ln-5 coated the most apical part of the enamel and the most coronal portion of the cementum, on either side of the CEJ [8].
  • MATERIALS AND METHODS: Sixty-four caries-free human maxillary central incisors were selected for standardized size and quality, endodontically treated, and decoronated 2 mm coronal to the cementoenamel junction [9].
  • With an intracoronal isolating base placed either at the cementoenamel junction (CEJ) or 2-mm below the CEJ, bleaching agents of Superoxol, sodium perborate, and a combination of the two were placed in the pulp chamber of teeth and the accesses sealed with IRM [10].

Associations of Tooth Cervix with chemical compounds

  • Sites were surgically exposed and measurements were recorded from the cemento-enamel junction (CEJ) directly coronal to the furcation area to the alveolar crest, and to the base of the defect [11].
  • In the outermost layers fluoride concentrations were highest in calculus found near the tooth cervix both in supra- and subgingival calculus [12].
  • Sodium perborate monohydrate (MH), trihydrate (TRH) or tetrahydrate (TH) was mixed with H2O2 or H2O and subsequently placed intracoronally 1 mm below the labial CEJ [13].
  • The teeth were decoronated at the level of the CEJ, accessed, instrumented to a Master apical file #50, irrigated with either sterile saline, 5.25% NaOCl, or 0.12% chlorhexidine gluconate, and dried using paper points [14].
  • Their crowns were separated at the cementoenamel junction and their roots were stored in sodium hypochlorite for 1 week [15].

Gene context of Tooth Cervix

  • The mean values of bone healing registered in mm from the cemento-enamel junction (CEJ) were 2.6 +/- 2.19 SD and 3.0 +/- 2.20 SD for test and control sites, respectively [16].
  • Direct measurements during surgery of the distance between the CEJ to the bottom of defects (ABL) were compared with probing to bone (PB), probing attachment level (PAL), and radiographic measurements [17].
  • METHODS: Large MOD cavities with cervical margins located 1mm below the CEJ were prepared in 48 extracted human molars [18].
  • The teeth were decoronated at the level of the cementoenamel junction, then accessed, instrumented to a Master Apical File #50, irrigated with either sterile saline, 5.25% NaOCl or 0.12% chlorhexidine gluconate, and dried using paper points [19].
  • Forty Class II cavities, with the gingival margins located at the cementoenamel junction, were restored with Palfique Estelite light-cured resin composite and one of two different bonding agents, All Bond 2 and Tokuso Light Bond, with or without the inclusion of glass-ceramic inserts [20].

Analytical, diagnostic and therapeutic context of Tooth Cervix

  • All materials and tooth preparations exhibited similar surface tangential stress patterns, with a definite compressive area at the external cusp ridges, a tensile zone at the occlusal surface, and compression stress peaks at the CEJ [21].
