Core build up using adhesive materials has become very popular due to many advantages of this technique.
Better aesthetics in the front region and better mechanical force distribution compared to metal posts are some of the advantages. Another enhancement would be the conservative preparation or even no post preparation for root canal treated teeth, where small calibre fiber post can be adjusted with minimum dentine loss preserving tooth resistance to fracture.
In the following clinical case, a maxillary second premolar presented with invading decays reaching the pulp chamber. The tooth was diagnosed with pulp necrosis needing root canal treatment. The preoperative xray revealed a 2 rooted premolar.
Special care was taken to preserve tooth structure as much as possible.
The purpose of this clinical Video is to highlight possible management of core build up of endodontically treated premolar teeth with ITENA Clinical Corono-Radicular Restoration Kit. It is important to highlight as well that small calibre Fiber Posts in different angulation helps achieving conservative mono block build up while preserving natural tooth structure.

Conclusions
In summary, Itena Clinical resin core build up kit is user friendly and with great working time before setting allowing an easy and hustle free build up. One millimeter diameter fiber posts can provide excellent restoration results with conservative build ups without any extra enlargement. Adequate steps for dentine or enamel preparation before and during bonding should be carried out for optimum result. Moreover, like in this case post were convergent in direction to the access cavity hence preserving more healthy dentine tissue. Finally, the clinician should respect all stages of the adhesive techniques taking special care for the time frame during etching and bonding of the tooth structures.
