ROCANAL
Root Canal Therapy

by Dr. Edgar J. Corneo-Lobenstein

A Biotechnical System Part II - Page 2
 

Two Different Cements
Two different cements have been realized to fill the root canal: the first (Rocanal R2) is used after vital pulpectomy, the second (Rocanal R3) after preparation and medication of gangrenous canals. Following bio-technical criteria, the first cement is oriented against autolytic processes, the second against heterolytic processes.

   
Endodontic Cement Programmed to fill the Root Canal after Vital Pulpectomy.
The endodontic cement is programmed to be active on pulp remnants remained after complete cleansing of root canal. The cement protects these remnants from autolytic and heterolytic processes. After vital pulpectomy, the filling should reach the apical constriction.
 
   
Endodontic Cement Programmed to fill the Root Canal after Treatment of Gangrene.
This cement is introduced preferably without guttapercha. The action is programmed to protect the canal from secondary infection (heterolysis), particularly under anaerobic condition. The intracanalar action is particularly active before cement setting.
   
Difference of Filling with Guttapercha
And with Endodontic Cements.

Guttapercha is irritant if it goes over the apex and is not resorbable. No active action in the canal.
Endodontic cements are, if programmed with a bio-technical system, active in the canal. They are resorbable if they reach the periodontal region. They are well tolerated if they reach involuntarily the periodontal area. They do not disappear from the canal.

Importance of Tolerance in Root Canal
Tolerance is synonimus of bio-technical method for treating root canal.
First of all it is the treatment method that must be controlled.

TOLERANCE
1. Treatment Methods
2. Toxicity: Irrigation-disinfection-filling
3. Action: how many - how long
4. Solubility
5. Resorbability

Photograph of a root canal filling with Rocanal endodontic cement only.
The filling is well adherent to the canal walls.
It reaches an unprepared "cul de sac".
