Effectiveness of the self-adjusting file versus ProTaper systems to remove the smear layer in artificially induced internal root resorption cavities

Comparision of Cleaning Efficiency of Rotary Protaper and Self Adjusting File in Oval Shaped Canals – An In- Vitro Study

“…The possible reason might be the lack of difference to the roundness of the apical anatomy and the minute difference may be because of long oval canals are more common in the apical 5 mm. 1,4,5 The SAF preparation was reported to result in significantly less untreated surface throughout the length of long oval canals when compared to the rotary protaper. SAF system was significantly more affective in disinfecting long oval canals.…”

“…One of the chief cause of endodontic failure is residual tissue, bacteria or debris. 1 Traditionally files have been used for root canal preparation and their effectiveness depends on several factors like file design, surface treatment and the ability to remove debris and smear layer. 2 Recently nickel-titanium (Ni-Ti) rotary file systems have been introduced which resulted in considerable improvement in the bio-mechanical preparation of the root canal space.…”

“…Since there are limitations in current technologies, there is a regular need for successful preparation techniques for better debridement of the root canal space. [1][2][3] Recently, the self-adjusting files (SAF) have been introduced in the field of endodontics, with entirely new design. SAF have been introduced, that is a hollow, flexible and compressible instrument made of 120-mm-thick NiTi lattice.…”

Obturação endodôntica termoplastificada

“…Vazio no canal também pode resultar de uso indevido. Existem dois sistemas de guta-percha injetáveis: um sistema usa uma guta-percha de alto ponto de fusão (160°C: a Obtura); o outro sistema usa um sistema de baixo ponto de fusão (60°C: Successfil) (SINGH et al, 2014;ÖZER et al, 2013). Ambos os sistemas funcionam extremamente bem quando os canais foram adequadamente preparados, limpos e secos.…”
