Computerized tomography in the management and follow‐up of extensive periapical lesion

Abstract

Radiographs are good diagnostic aids in endodontics, although they have limitations. The purpose of this article is to discuss the use of computerized tomography in differential diagnosis, treatment planning, follow-up and overall clinical management of complex periapical lesions. A clinical case of an extensive symptomatic periapical lesion of the upper jaw is presented, in which the use of computerized tomography allowed evaluation of the true extent of the lesion and its spatial relationship to important anatomical landmarks. Computerized tomography also provided specific information about the type of lesion and the degree of bone repair which had taken place 18 months after non-surgical treatment had been completed.

Hypohidrotic Ectodermal Dysplasia: A Casereport and Literature Review

“…The characteristic facial features are: frontal bossing, depressed nasal bridge, prominent supra orbital ridges, prominent and obliquely set ears , midface is depressed, the lower third of the face appears small due to lack of alveolar bone development, lips are protuberant 3,8 .Oligodontia is the most characteristic feature of the oral cavity. The teeth that are present have abnormal crown form which is conical in shape 9 . Cases have been reported where both primary and permanent dentition were congenitally missing 10 CONCLUSION: In this report we highlighted on the extra oral and intraoral findings of Hypohidrotic ectodermal dysplasia.…”

Maxillary odontogenic keratocyst: a clinical case report

“…On the other hand, computed tomography allows for the accurate assessment of the true extent of the lesion and its relationship to important anatomic structures, contributing to surgical planning [11][12] . Radiological examination shows lesions with unilocular or multilocular appearance due to their size.…”

Estudo comparativo entre as tomografias computadorizadas 3D, ortopantomográficas e radiografias periapicais no diagnóstico de lesões periapicais, fraturas radiculares e reabsorções dentais

“…A radiografia panorâmica tem sido utilizada, pela sua simplicidade, na visualização de ambas as arcadas dentárias, em uma única tomada (BOCAGE, 1922;NUMATA, 1934;PAATERO, 1949;PAATERO, 1958 (COTTI et al, 1999;HEO et al, 2000).…”

“…(TAMISALO et al, 1996;COTTI et al, 1999;HEO et al, 2000;BERTOLLO et al, 2000;VELVART;HECKER;TILLINGER, 2001;BRAMANTE, 2002;PINSKY et al,2006;BERNARDES et al, 2006;NAIR,2007;LOFTHAG-HANSEN et al, 2007;TANTANAPORNKUL et al, 2007). O baixo índice de diagnóstico de fraturas nas radiografias periapicais, contrapondo-se à TC, foi devido à ausência de condições nítidas, como linhas de fraturas em direção à raiz, ou à obturação dos canais, espaço entre a parede do canal e a obturação, perdas ósseas, perda da continuidade do ligamento periodontal e halos radiolucentes.…”

“…Ficou clara a melhor qualidade diagnóstica com a TCCB, o que corrobora os resultados, também melhores, de trabalhos, desde o uso da TC convencional (TAMISALO et al, 1996;COTTI et al, 1999;HEO et al, 2000;BERTOLLO et al, 2000;VELVART;HECKER;TILLINGER, 2001;BRAMANTE, 2002), até os últimos anos, com TCCB (PINSKY et al, 2006;BERNARDES et al, 2006;LOFTHAG-HANSEN, et al, 2007;TANTANAPORNKUL et al, 2007;COHENCA et al, 2007;MORA et al, 2007). O índice de fraturas detectadas por ambos os examinadores foi de 56 e 34 casos, com escores 1 e 2.…”
