  • 5. CONVENTIONAL IMAGING TECHNIQUES PERIAPICAL RADIOGRAPHS PANORAMIC RADIOGRAPHS 1: EASY 2:ECONOMICAL LACK OF PERCEPTION IN THIRD DIMENSION www.indiandentalacademy.com
  • 6. DENTASCANS• Dentascan, was developed by Schwarz et al. in 1987 www.indiandentalacademy.com Schwarz MS, Rothman SL, Rhodes ML, Chafetz N . Computed tomography.I. Preoperative assessment of the mandible for endosseous implant surgery. Int J Oral Maxillofac Implants 1987 2:137–141
  • 7. DENTASCANS PRIMARYINDICATIONS Pre-evaluation of implant sites Buccolingual extent of cysts and tumours Inflammatory lesions of the jaws www.indiandentalacademy.com
  • 8. CASE REPORT• 45 yr male patient• Chief complaint : Swelling in right side of face.• Medical history was not significant.• Badly carious maxillary right first molar with obliteration of buccal vestibule www.indiandentalacademy.com
  • 9. IOPAwww.indiandentalacademy.com
  • 10. Extra canals in right maxillary molars Extra canals in maxillary left first and second molars www.indiandentalacademy.com
  • 11. Axial image showing extra canals in multiple teeth www.indiandentalacademy.com
  • 12. : Axial image showing loss of cortical plate in distobuccal and palatal root of 3D image showing loss of palatal and right maxillary first molar buccal cortical plate www.indiandentalacademy.com
  • 13. Paraxial image of maxillary first molar showing MB root with periapical infection with maxillary sinus inflammation www.indiandentalacademy.com
  • 14. 3D volume rendering showing loss of 3D volume rendering showing furcation buccal cortical plate in right involvement with left mandibular second molar maxillary first molar region www.indiandentalacademy.com
  • 15. Mandibular anterior region showing periapical infection with loss of labial cortical plates www.indiandentalacademy.com
  • 16. www.indiandentalacademy.com
  • 17. LIMITATIONS OF TWODIMENSIONAL IMAGING•Extra canals are a common findings andmissing of these canals leads to endodontictreatment failure.•Intra oral radiographs - anatomy in thethird dimension cannot be assessed www.indiandentalacademy.com
  • 18. Root canals tend to lie one behind theother in buccolingual plane, they getsuperimposed onto each other onperiapical & panoramic radiographsand easily go undetected Soraya Robinson, C. Czerny, A. Gahleitner, T. Bernhart and F. M. Kainberger www.indiandentalacademy.com ,Dental CT evaluation of mandibular first premolar root configurations and canal variations . Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2002;93:328-32
  • 19. Dental CT : An alternative•Dental CT is reformatting softwareused along with spiral /helical CT andallows assessment in all threedimensions.•It provides axial, panoramic,paraxial and 3D volume renderingwhich helps in diagnosis purpose www.indiandentalacademy.com
  • 20. Orientation of the scan Maxilla: Parallel to the hard palate Mandible: Parallel to the alveolar ridge or the inferior border of mandible www.indiandentalacademy.com
  • 21. Marking of points along the ridgewww.indiandentalacademy.com
  • 22. Paraxial images markings www.indiandentalacademy.com
  • 23. Panoramic images markings www.indiandentalacademy.com
  • 24. 3D volume rendering showing loss of 3D volume rendering showing furcation buccal cortical plate in right involvement with left mandibular second molar maxillary first molar region www.indiandentalacademy.com
  • 25. Present case• . •Access cavity revealed five canals. •Dental CT determined the extend of periapical infection associated with the tooth along with loss of cortical plates , thereby helping in determining the treatment plan & prognosis of the tooth www.indiandentalacademy.com
  • 26. MAXILLARY SINUS HYPERPLASIA• Hyperplasia of maxillary sinus mucosa was seen, suggesting that periapical infection could be the initiating factor for hyperplasia of mucosa www.indiandentalacademy.com
  • 27. MULTIPLE EXTRA CANALS• Extra canals were also found in other teeth with periapical infections in lower anterior teeth. www.indiandentalacademy.com
  • 28. Limitations of Dentascans Cost factor Radiation dose www.indiandentalacademy.com
  • 29. CONCLUSION•Radiographic examination is an essential part ofdiagnosis in endodontic. Two dimensional imagingcannot depict variations in root canal morphologylike extra canals & the extent of the periapicalinfection. This limitation of two dimensional imagingis overcome by Dentscan. Dentascan in time maychange the way in which the outcome of theendodontic treatment is assessed www.indiandentalacademy.com
