“…In this case, anatomical information is also missing as many frequently used bone substitutes are made of, or contain, calcium phosphates with similar radiopacity to the bone. Therefore, such substitutes are difficult to distinguish from the surrounding natural tissue by means of conventional techniques (Pekkan et al, 2012), even though recent attempts have been made using high-resolution micro-CT or X-ray microdiffraction analysis (i.e. synchrotron radiation) (Gauthier et al, 2005;Mastrogiacomo et al, 2005;Papadimitropoulos et al, 2007;Komlev et al, 2010).…”

Quantification of the bone healing processes by X-ray-based methods becomes inaccurate in the presence of radiopaque synthetic materials. In this study, single photon emission computed tomography (SPECT) and positron emission tomography (PET) were compared as alternatives to follow in vivo bone healing in a rat calvarial defect model. SPECT/computed tomography (CT) following administration of technetium-labelled hydroxymethylene diphosphonate ( Tc-HDP) and PET/CT data with F-fluoride were acquired up to 10 weeks after surgery. New bone formation was then confirmed by histology. Computed tomography scans allowed visualization of untreated bone defect healing; however, no information was gathered in presence of the ceramic. Positron emission tomography provided superior data compared with SPECT. The F-fluoride uptake increased significantly up to 4 weeks after surgery, declining thereafter until the last time-point. In vivo performances of porous versus dense ceramic scaffolds were also evaluated by PET, with a significantly higher uptake registered within the porous scaffolds. In conclusion, PET is a valuable tool for qualitative/quantitative follow-up of bone healing around radiopaque bone substitutes in vivo. Copyright © 2014 John Wiley & Sons, Ltd.

“…Although some research reported differences of radiopacity between different bone graft materials (Pekkan et al, 2012), the present research suggest that radiographic tests are inefficient for assessing tissue repair process when using non autogenous material; radiography analyses serve as a parameter in the follow-up for reconstructions when using autogenous bone grafts. …”

SUMMARY:Surgical procedures involving the rehabilitation of the maxillofacial region frequently require use of bone grafts. Bone graft follow-up is generally done through clinical analysis and especially through image tests, although few studies specifically correlate both. The object of this research was to establish a relation between radiographic exams and the bone repair process stage in created defect with autogenous bone, blood clot and anorganic bovine bone matrix. Three 8 mm diameter defects were performed in the parietal bone of 6 male adult beagle dogs, choosing the selected graft for each defects; 3 and 6 week period were used for radiographic and histological analyses. The result show that autogenous bone and blood clot were similar between histological and radiograph analyses; for heterogeneous bone was present areas described how bone in radiograph that were residual particles in histological exam. We concluded that radiographic tests could be used as a parameter for reconstruction follow-up only when autogenous bone graft is used.

“…In experimental research, micro computed tomography and microradiographs are frequently used for objective evaluation of bone quality as represented by measurements of bone mineral density and bone microstructure (Matsuo et al, 2011;Nolff et al, 2010;Pekkan et al, 2011). For clinical application these techniques are not available and computed tomography (CT) or CBCT is used instead.…”
