Abstract(s)
Recentemente, um novo conceito de cavidade endodôntica conservadora (CEC) foi planeado e desenvolvido com o objetivo de minimizar a remoção do teto da câmara pulpar e da dentina pericervical.
Esta abordagem visa evitar a remoção excessiva de dentina das estruturas dentárias que dão resistência ao dente. A remoção dessas estruturas de carácter crucial compromete a resistência dos dentes endodonciados quando submetidos a cargas funcionais, sendo a exodontia a consequência mais frequente da fratura desses dentes. A literatura atual não é unânime quanto aos benefícios no que diz respeito às CECs, pois ainda não há evidências claras na literatura que apoiem as CECs, mais estudos clínicos com controlos alargados são necessários para avaliar como é que este tipo de cavidade de acesso pode afetar o sucesso clínico. O objetivo do presente trabalho foi analisar a influência das CEC, na resistência à fratura de dentes endodonciados, em comparação com as cavidades tradicionais.
Recently, a new concept of conservative endodontic cavity was planned and developed with the objective of minimizing the removal of the pulp chamber roof and pericervical dentin. This approach aims to avoid excessive removal of dentin from tooth structures that give strength to the tooth. The removal of these crucial structures compromises the strength of endodontically treated teeth when subjects to functional loads, with extraction being the most frequent consequence of fracture of these teeth. The current literature is not unanimous on the benefits of this kind of approach, more clinical studies with expanded controls are needed to assess how this kind of access cavity can affect clinical success. The aim of the present work was to analyse the influence of conservative endodontic cavity on the fracture resistance of endodontically treated teeth in comparison with traditional cavities.
