“…19,35,36 A retrospective clinical study reported a survival rate of root filled teeth restored with either a prefabricated post or a cast post to be 83% over a 10 year period. 37 On the other hand placement of a fibre post with or without cusp capping with resin composite did not result in additional benefit compared to composite resin restoration without post and cusp capping. 38 One study 27 found that glass fibre posts reduced fracture resistance of root filled teeth with moderate tooth structure loss and did not restore the fracture resistance of teeth with major loss of tooth structure.…”

“…The most unfavorable failures associated with this type of system are loss of retention due to displacement 12,13 , root fractures 14 , and risk of corrosion 2,15 . In search for the origin of these failures, authors have suggested that the problem lies in the way cast posts and cores are being manufactured 3,[5][6][7]13 . Aiming to reduce these failures, prefabricated posts have appeared as new option of simpler and faster confection; however, care must be taken when performing additional denture wear maneuvers to adapt the root canal space to the selected post shape in order to avoid weakening of the dental remnant and/or root perforations 16 .…”

ResumoIntrodução: Dentes com ampla destruição coronária e tratados endodonticamente necessitam de retentores intrarradiculares para viabilizar a restauração protética. Apesar do crescente uso de pinos intrarradiculares pré-fabricados, os retentores intrarradiculares metálicos fundidos ainda são muito utilizados. A qualidade desses é importante para a longevidade do tratamento restaurador, pois podem levar ao insucesso quando seus princípios fundamentais não são seguidos. Objetivo: Avaliar radiograficamente os princípios protéticos de 1000 retentores intrarradiculares metálicos fundidos em dentes unirradiculares e a coerência dos mesmos com os princípios para sua confecção. Material e método: Foram selecionadas radiografias periapicais digitais de 1000 dentes unirradiculares que receberam tratamento endodôntico e retentores intrarradiculares metálicos fundidos, através do acervo de uma clínica radiológica (Centro de Imagem, Aracaju/SE, Brasil). As imagens foram analisadas através de um software de mensuração (ImageJ, EUA) de acordo com os princípios fundamentais protéticos: comprimento e diâmetro do pino, relação do pino com a crista óssea, contiguidade ao canal, espaço entre o remanescente obturador e o pino, quantidade de material obturador e ausência de lesão periapical. Os dados foram tabulados, analisados qualitativamente em ideais e não ideais e submetidos ao teste do Qui-Quadrado (α=0,05). Resultado: Apenas 6,7% dos retentores intrarradiculares fundidos analisados foi confeccionado de forma satisfatória. Conclusão: Muitos critérios protéticos são negligenciados durante a confecção de retentores intrarradiculares metálicos fundidos, resultando em trabalhos inadequados que podem comprometer a longevidade do tratamento restaurador.Descritores: Técnica para retentor intrarradicular; pinos dentários; prótese dentária; radiografia. AbstractIntroduction: Endodontically treated teeth with extensive coronary destruction require posts and cores to enable prosthetic restoration. Despite the increasing use of prefabricated posts, cast metal posts and cores are still widely used. The quality of the latter is important for the longevity of restorative treatment, and failure can occur if the fundamental principles are not followed. Objective: To radiographically evaluate the prosthetic principles of 1000 cast metal post-and-core restorations performed in single-rooted teeth and their coherence with the principles used for their confection. Material and method: Digital periapical radiographs of 1000 endodontically treated, single-rooted teeth with cast metal posts and cores were selected from the collection of a radiology clinic (Centro de Imagem, Aracaju/SE, Brazil). The images were analyzed using a measurement software (ImageJ, USA) in accordance with the fundamental prosthetic principles: length and diameter of the post, ratio between post and bone crest, contiguity of post to the root canal, gap between post and the remaining root canal filling, amount of remaining root canal filling, and absence of periapical lesion....

“…The importance of preserving a minimum amount (2 mm) of coronal dentine height after preparation, known as ''ferrule effect'', on the fracture resistance and prevention of root fracture of ETT has been reported in various studies [7][8][9][10][11] although other studies refute this statement. [12][13][14] It has been reported that when the ferrule effect is present, stresses are redistributed in the outer surface regions of the coronal third of the root 15 thus a possible fracture in this area can be repairable.…”
