[New cement filled with hydroxyapatite. Preliminary clinical results].

After histological, scanning-electromicroscope, stereomicroscope and transillumination controls, the clearing technique definitively demonstrated that it's really impossible to empty and entirely fill the endodontic apical extremity inside the correct limit, without running the risk to cause iatrogenesis interferences against periodontal reparation processes. Then also the "tridimensional fill" conception, as a simple "seal by physical push", must be integrated with the conception of root canal sealer materials biocompatibility toward the periodontal tissues. "Bioseal" root canal sealer which is the subject of this research is certainly an example of progress about this objective.

[Diaphanization. Testing method for endodontic technics].

It's a study about the principal clearing techniques, with a selection of materials and phases of execution. The purpose was to obtain transparency of mineralized structure together with preservation of pulpal contents. From this research a technique has been extracted and positively tested, with great results: a) tridimensional control of alterations pointed out in anatomy after canal preparation; b) measurement of pulpal debris size after instrumentation; c) identification of instruments dark zone; d) measurement of the empty-cleansing capacity of root canal system and the defence from eventual self-made errors, as a result of particular operating techniques, whose comparison is accessible by methodology.

[Study of canal anatomy using longitudinal sections, castings and diaphanization].

It is well known, that to make a correct root canal treatment, it is indispensable to know perfectly the root canal morphology. The study with the longitudinal sections M.-D. and V.-B., stamps and transparent teeth gives us an unquestionable reality. Specially the V.-B. longitudinal sections, which are impossible to observe in the patient with our Rx, are the most instructives. In spite many authors have illustrated this anatomy (Hess, De Deus, Kuttler, Riitano), it seems it has not been sufficiently considered.
