ABSTRACT
To characterize the maxillofacial bone lesions by associating clinical and imaging aspects, through Cone Beam Computed Tomography (CBCT) and compare the findings with those reported by the literature. Material and

Methods:

Twelve files were selected from the Clinics of Stomatological Propedeutics (ICT-UNESP) reporting maxillofacial bone lesions with previous CBCT indication. CBCT was carried out withi-CAT Next Generation scanner (imaging Sciences International, Hatfield, PA, USA) at the Radiology Clinics of the institution. First, we recorded the clinical information on gender, age range, and main complaints. Then, CBCT images were assessed regarding to site, lesion internal architecture and limits, effect on bone corticals, effect on teeth and support structures, and the lesion internal aspects. All images were evaluated with the aid of i-CAT Vision software at multi-planar reconstruction model (MPR).

Results:

We studied four root cyst lesions, two keratocystic odontogenic tumors, one compound odontoma, one odontogenic hamartoma, one focal osseous dysplasia, one calcifying cysticodontogenic tumor, and two fibrous scars. CBCT helpedin achieving the diagnosis because of tridimensionality, but sometimes, the lesion characteristics disagreed from those described in the literature because the latter were based on two-dimensional radiographs.

Conclusion:

CBCT is highly valuable in characterizing bone lesions, but the literature demands a specific approach for CBCT images because the latter differs from conventional radiographic images...
RESUMO
Caracterizar as lesões ósseas da região maxilofacial conjugando seus aspectos clínicos ao simaginológicos, por tomografia computadorizada de feixecônico (TCFC), comparando estes achados da literatura.Material e

Métodos:

Foram selecionados 12 prontuários da Clínica de Propedêutica Estomatológica do ICT-UNESP, apresentando lesões ósseas na região maxilofacial, com prévia indicação de exame por TCFC, realizados em tomógrafo i-CAT Next Generation (imaging Sciences International, Hatfield, PA, EUA) na clínica de Radiologia da instituição. Foram levantadas informações clínicas como sexo, faixa etária e queixas principais. Avaliou-se as imagens de TCFC quanto localização, arquitetura interna e limites da lesão, efeito nas corticais ósseas, efeito nos dentes e estruturas de suporte dentário e os aspectos internos da lesão. As imagens foram avaliadas no software i-CAT Vision do tomógrafo em janelas de reconstrução multiplanar (MPR).

Resultados:

Foram estudadas 04 lesões correspondentes a cistos radiculares, 02 a tumores odontogênicos queratocísticos, 01 a odontoma composto,01 a hamartoma odontogênico, 01 a displasia óssea focal, 01 tumor odontogênico cístico calcificante e 02 cicatrizes fibrosas. A TCFC auxiliou na conclusão dos diagnósticos, visto sua característica de tridimensionalidade, houve,algumas vezes, divergências em relação aos achados descritos na literatura, eminentemente baseados radiografias bidimensionais.

Conclusão:

a TCFC é de grande valia na caracterização das lesões ósseas, observa se uma necessidade na literatura de uma abordagem específica para esta modalidade de imagens, diferente das radiográficas convencionais...
