Influence of smear layer treatment on resistance to root fracture in tooth restored with epoxy fiber post.

Haralur SB1, Al Faifi AH1, Al-Qahtani SS2.Author information 1Department of Prosthodontics, College of Dentistry, King Khalid University, Abha, Kingdom of Saudi Arabia.2Department of Periodontology, College of Dentistry, King Khalid University, Abha, Kingdom of Saudi Arabia.AbstractTo evaluate the influence of complete smear layer removal by EDTA on the resistance of root fracture of tooth restored with fiber post. Twenty single rooted premolars with average root length 16 ± 1 mm were randomly divided into two groups of ten each. All teeth were obturated with guttapercha after root canal preparation, sectioned 4 mm above the cement-enamel junction. In group I, teeth root canals were etched with 37 % phosphoric acid, fiber post cemented with self adhesive resin cement. In group II, teeth radicular dentin was treated with 17 % EDTA, followed by fiber post cementation with dual cure resin cement. Coronal part of the teeth reestablished with posterior composite and NiCr full veneer coping along with 2 mm circumferential ferrule. Restored teeth were loaded with incremental force at 30° to the long axis of the root until fracture occurred. The data obtained was evaluated with paired sample T test to compare the fracture resistance between the test groups. Group I had the mean failure load of 1,883.70 N while group II had 1,622.80 N mean failure load. Paired sample T test showed statistically significant (p value = 0.033) failure load difference between the groups tested. Within the limits of this study, it may be concluded that: the complete removal of smear layer by EDTA found to have reduced the fracture strength of tooth roots restored with an epoxy fiber post.

Effect of intraoperative weight-bearing simulation on the mechanical axis in total knee arthroplasty.

Panzica M1, Kenawey M, Liodakis E, Brandes J, Krettek C, Hankemeier S.Author information 1Department of Trauma Surgery and Orthopaedic Surgery, Hannover Medical School, Carl-Neuberg Str. 1, 30625, Hannover, Germany, panzica.martin@mh-hannover.de.AbstractPURPOSE: Successful outcome after total knee arthroplasty (TKA) requires precise realignment of the mechanical axis. The intraoperative assessment of the mechanical axis is difficult. Intraoperatively, the effect of weight bearing on the lower limb mechanical axis is ignored. We developed a custom-made mechanical loading device to simulate weight-bearing conditions intraoperatively and analysed its effect on the mechanical axis during TKA.
