Akkayan, B., Gulmez, T.: Resistance to fracture of endodontically treated teeth restored with different post systems. J Prosthet Dent 2002; 87:431-7.
Conclusions: Within the limitations of this study, significantly higher failure loads were recorded for root canal treated teeth restored with quartz fiber posts (DT LIGHT-POST). Fractures that would allow repeated repair were observed in teeth restored with quartz fiber and glass fiber posts.
Grandini, S., Goracci, C., Monticelli, F., Tay, F.R., Ferrari, M. Fatigue resistance of different kinds of fiber posts.
J Dent Res. Vol 82 IADR Abstract #2935, 2003.
Conclusions: the statistical analysis is highly significant: different kinds of fiber posts give different results when they undergo a fatigue resistance test.

Conclusions: Using the Anatomic Post n Core (RTD, St. Egreve, France) results in a better post adaptation and, thus, a thinner, more uniform film of cement.

Conclusions: A 2mm ferrule improves failure resistance of endodontically treated teeth with bonded (DT LIGHT-POST) fiber posts and resin cores.
Pitel, M. L., Hicks, N. L. Evolving technology in endodontic posts. Compendium 24 13-29, 2003.
Conclusions: The use of a highly translucent post not only can serve to enhance esthetics in the final restoration, but can also be useful as an instrument in the light-curing process.

Conclusions:
1. the adhesion of composite resins to quartz fiber posts is higher than to carbon fiber posts,
2. on quartz fiber posts, dual-curing composites lead to a stronger adhesion that light–curing composites and
3. on carbon fiber posts, only negligible differences exist between dual and light-curing composites.
Scotti, R., Malferrari, S. Prosthetic aspects of endodontically treated tooth restoration. Proceedings from the 5th International Symposium. 27-33, 2001.
Conclusions: DT LIGHT-POST demonstrated optimal fit to the morphology of canals prepared by the most widely-used endodontic techniques in 90% of cases. In in vitro evaluation between morphological congruity of the site preparation and the DT LIGHT-POST; the cement thickness is never greater than 500 microns at any point of post circumference.
Glazer, B. Endodontic post evolution: from metal to quartz. Oral Health, May, 2002 43-45.
Conclusions: Transition from Carbon to Quartz was completed without any compromise in strength, modulus of elasticity, resistance to fatigue or the ability for re-treatment. The Light-Post offers significant aesthetic and clinical advantages due to its translucency.

J Dent Res 81 IADR Abstract #2569; 2002.
Conclusions: The composite resins were photopolymerized using the LIGHT-POST #3. These results suggest that irradiation for over 40 seconds can effectively polymerize a highly translucent resin in clinical practice.
Bassi, M. Light diffusion through double taper quartz-epoxy fiber posts. Proceedings from the 5th International Symposium. 21-26, 2001.
Conclusions:
1. An increase in the cross-section of DT LIGHT-POSTs increases their ability to transmit light from a distance.
2. The angle of the lamp tip conditions the entity of diffusion into the post.
3. Trans-illumination of the post must be aimed at its stabilization into the canal, to allow for immediate coronal restoration.
4. The use of dual-cured cements to attach posts is suggested even if the posts allow good light diffusion.
Sakkal, S. and Boudrias, P. New Developments in fiber post systems: the DT-Post one step closer to the ideal shape! Proceedings from the 4th International Symposium. 10-14, 2000.
Conclusions: The new DT-Post system was designed with the purpose of providing close canal adaptation with minimal tooth structure removal, and seems to offer a logical solution in restoring endodontically-treated teeth.
Malferrari, S, Baldissara, P, Arcidiacono, A, Translucent quartz fiber posts: a 20 month in vivo study. J Dent Res. 81 IADR Abstract #2656; 2002
Conclusions: No failures took place up to the present day. According to these results, and within the limitations of this study, it is possible to assume that the clinical performance of these translucent RTD fiber posts is successful.
Cormier, C., Burns, D., Moon, In vitro comparison of the fracture resistance and failure mode of fiber, ceramic, and conventional post systems at various stages of restoration. J Prosthodont 2001; 10:26-36.
Conclusions: The fiber posts evaluated provided an advantage over a conventional post that showed a higher number of irretrievable post and unrestorable root fractures. At the stage of final restoration insertion, there was no difference in force to failure for all but the FiberKor material, which continued to be weaker than all other materials tested. The fiber posts were readily retrievable after failure, whereas the remaining post systems tested were non-retrievable.
