  • Tissue surrounding the apex of a tooth, including the apical portion of the periodontal membrane and alveolar bone. (lookformedical.com)
  • Endodontic treatment is primarily dedicated to the preservation of teeth and their function. (clinicalresearchdental.com)
  • Non vital tooth bleaching is a conservative and esthetic alternative in the treatment of teeth darkened after endodontic treatment, offering greater preservation of tooth structure, at low cost when compared with more invasive procedures, such as fabrication of veneers or total crowns, restorative maneuvers or even the association of restorative and bleaching techniques 3-9 . (bvsalud.org)
  • Considering this, the discoloration of one or more teeth in the anterior region becomes particularly noticeable and may have a psychological impact on the patient. (clinicalresearchdental.com)
  • The dentine-bonding of a fractured non-vital anterior tooth. (lookfordiagnosis.com)
  • Moreover, maxillary anterior teeth are at high risk of traumatic root fracture, even when intact, due to frequent subjection to impact from horizontal forces [ 15 - 18 ]. (opendentistryjournal.com)
  • Sufficient tooth length, achieved through forced eruption, ensures the periodontal health of the "biologic width" and crown margin and thus a successful restorative outcome. (lookfordiagnosis.com)
  • Endodontic-periodontal lesions present challenges to the clinician as far as diagnosis and prognosis of the involved teeth are concerned. (docshare.tips)
  • Kirkham (13), studying 1000 human teeth with extensive periodontal disease, found only 2% of lateral canals associated with the involved periodontal pocket. (docshare.tips)
  • Tooth 21 was non-vital and additionally diagnosed with a chronic apical periodontitis, which has been treated endodontically. (clinicalresearchdental.com)
  • When there is pulpal involvement of permanent teeth with incompletely formed roots, techniques for the induction of apical closure should be completed before endodontic therapy is begun. (lookfordiagnosis.com)
  • As the tooth matures and the root is formed, three main avenues for exchange of infectious elements and other irritants between the two compartments are created by (1) dentinal tubules, (2) lateral and accessory canals, and (3) the apical foramen. (docshare.tips)
  • It is estimated that 30-40% of all teeth have lateral or accessory canals and the majority of them are found in the apical third of the root (1). (docshare.tips)
  • DeDeus (12) found that 17% of teeth presented lateral canals in the apical third of the root, about 9% in the middle third, and less than 2% in the coronal third. (docshare.tips)
  • OBJECTIVE: To compare the biomechanical properties of different endocrown designs on endodontically treated teeth with an extensive defect in the mesial wall using a three-dimensional finite element method (3D FEM). (bvsalud.org)
  • Use of composite resin and glass fiber-reinforced epoxy resin post system may reinforce residual tooth structure. (opendentistryjournal.com)
  • The purpose of this study was to compare impact-induced strain on the core and root surfaces between teeth treated with a conventional cast post-core system (Metal PC) and those treated with a glass fiber-reinforced epoxy resin post and composite resin post-core system (Fiber-Resin PC). (opendentistryjournal.com)
  • The teeth of the first dentition, which are shed and replaced by the permanent teeth. (lookformedical.com)
  • One of the eight permanent teeth, two on either side in each jaw, between the canines (CUSPID) and the molars (MOLAR), serving for grinding and crushing food. (lookformedical.com)
  • Tooth extraction has to be eventually performed in most such cases of root fracture, indicating the need to prevent such injuries from occurring in the first place. (opendentistryjournal.com)
  • One study [ 14 ], however, reported that failure significantly increased as load angle approached parallelism with the long axis in teeth restored with cast-post and cores and crowns. (opendentistryjournal.com)
  • The situations presented demonstrate techniques for bleaching with carbamide peroxide in a traditional nightguard or with an inside-outside technique to achieve acceptable esthetic results on isolated nonvital discolored teeth. (lookfordiagnosis.com)
  • A vertical load parallel with the longitudinal axis of the tooth and an oblique load with a 45°angle to the longitudinal axis were applied to the occlusal surfaces. (bvsalud.org)
  • Frequently, the teeth are a source of personal dissatisfaction, and color change is one of the reasons for seeking dental treatment 1 . (bvsalud.org)
  • This is why tooth bleaching is one of the most sought-after esthetic treatments in dental offices 2 . (bvsalud.org)
  • Although these techniques may not be effective in all cases, they do not compromise or eliminate any future treatment options. (lookfordiagnosis.com)
  • Most endodontically treated teeth are restored with some kind of prosthesis such as a crown or bridge after application of a post-core system. (opendentistryjournal.com)
  • Therefore, when such teeth are treated with a post-core and crown or an abutment for a bridge, they become even more susceptible to damage from impact force. (opendentistryjournal.com)
  • This suggests that a Fiber-Resin PC is more suitable for non-vital teeth against not only occlusal but also traumatic impact force. (opendentistryjournal.com)
  • Their incidence and location have been well documented in both animal and human teeth (9-15). (docshare.tips)
  • To the best of our knowledge, fracture resistance in teeth treated with a post-core system has only been examined using static loading [ 2 - 7 , 9 , 10 , 19 - 21 ] or finite element analysis that assumed occlusal force [ 7 , 22 ]. (opendentistryjournal.com)
