DIREctIONS FOR uSE (Cavity Access Kit)
1) INDIcatION FOR uSE
These products have to be used only in hospital environments, clinics or dental offices by qualified den tal
personne.
Application field: A set of rotary cutting instruments utilized for initiating, progressively expanding and then
finishing the endodontic access preparation. Complete access improves diagnostic, root canal treatment or
retreatment success.
OBJEctIVES
The access cavity should be prepared so that, when present, all restorative materials and tooth structure,
including the entire pulpal roof, are removed. The axial walls are extended laterally such that the orifice(s)
are just within this outline pattern. Access objectives are confirmed when all the orifices can be visualized
without moving the mouth mirror.
2) cONtRa-INDIcatIONS
not known
3) WaRNINGS
• The instruments should not be totally immersed in 5 % sodium hypochlorite for a period exceeding
5 minutes.
• The instruments utilized should not be immersed for more than 15 minutes in a decontamination
tray.
4) PREcautIONS
• Carefully review different horizontally angulated radiographs to observe the relationship between
the clinical crown and the underlying roots. Try to visualize the size and depth of the pulp chamber
and if stones are present.
• Auxiliary magnification and lighting devices, such as the dental operating microscope, promote
safe, efficient and predictably successful treatment.
• Use new burs, and when appropriate, with a water spray to improve tactile control, decrease heat
build-up and the potential for clinical mishaps.
• Use a fulcrum when cutting to avoid skipping and procedural accidents.
• The longer length carbide round burs may be used as side cutting instruments when there is
narrow intra-occlusal space.
• Use the long tapered diamond bur (Cavity Access Set) or the Endo-Z (Cavity Access Z Set) to
flatten, wippen and finish the internal axial walls. The abrasively coated rounded tip of the tapered
diamond bur enables you to precisely finish the pulpal floor too.
• Use the X-Gates, with a brushing action on the withdrawal stroke, to intentionally relocate the canal
away from furcal danger.
5) aDVERSE REactIONS
A lack of judgment, anatomical knowledge or clinical training or the improper use of any rotary cutting
instrument may contribute to iatrogenic dentistry.
6 StEP BY StEP INStRuctIONS
Predictably successful endodontic treatment starts with complete access. There is an old expression "start
with the end in mind". Visualize complete access and select the appropriate rotary instrument for each step-
by-step procedure to improve diagnostic, treatment or retreatment success.
6.1) ROtaRY INStRuMENt SELEctION
Carefully inspect the tooth to be endodontically treated to determine if the crown is natural and intact,
cariously involved or fabricated with a metal or tooth-colored restorative. The rotary instrument selected is
based on the type of material to be removed.
6.2) tOOtH cOLOR REStORatIONS
se the round bur diamond with a light brush-cutting action and water spray to progressively sand away and
eliminate tooth-color restoratives.
