Root Canal Procedure. Case Study Number 451
A Vertucci type V pulp space configuration can be described as follow: One canal leaves the pulp chamber and divides short of the apex into two separate distinct canals with distinct foramina (1-2). According to Vertucci’s study in 1984 on a 100 mandibular molars sample, the type V configuration in distal root, occured only in 8% of the teeth examined. In the apical third of distal root, each part of the split as been individually cleaned, shaped and filled with gutta Percha and Pulp Canal Sealer.
Second lower right molar. Type V canal configuration in a long distal root with a lateral accessory canal. Severe curve in both mesial canals. Immediate post operative X ray film to the right shows some root canal sealer extrusion.
Root canal sealers, as we (dental professionals) all know,
” are necessary to seal the space between the dentinal wall and the obturating core material. Sealers are necessary to fill voids and irregularities in the root canal, lateral and accessory canals, and spaces between gutta-percha points used in lateral condensation “
Lack of bone structure in periradicular tissues combined with lateral and warm vertical gutta-percha condensation makes it virtually impossible for a clinician who truly wants to seal all portals of exist not to have sealer extrusion as shown above. Zinc oxyde-eugenol extruded sealer does not have any negative impact on root canal success rate. This type of sealers will always resorb if extruded into the periradicular tissues as shown in this 5 years post op X ray. The sealer I like to use on a regular basis: Pulp Canal Sealer
