Large Volume Veterinary Endodontic Syringe™
The Large Volume Veterinary Endodontic Syringe™ is an endodontic syringe developed by Dr. John Scheels specifically for veterinary use in all species for complete and consistent obturation of root canals over 30mm long or with large pulp chambers.
It permits the positive deposition of endodontic sealer and filler pastes at the apex of these long teeth. NO SPECIAL NEEDLES are required as it may be used with any standard size hub. Plastic, metal, threaded or non-threaded needle hubs will seal well on the tapered syringe nipple.
Directions for use of the Large Volume Veterinary Endodontic Syringe®
Endodontic paste of your choice, or simply zinc oxide powder and eugenol
are mixed to a very thick consistency, similar to cream cheese or heavier.
Mix enough paste to more than fill the canal and chamber. A 2" or 3" 18 gauge needle is a good choice for reaching the apex of the root canal in cases such as large canid or felid cases.
Fill the needle hub with paste. Attach the hub to the syringe and thread on the needle. Either plastic or metal, threaded or non-threaded needle hubs will seal well on the tapered syringe hub nipple. Place the plunger into the syringe and engage the threads. Turn the plunger to extrude the paste from the needle.
After drying the prepared canal, fit the master gutta percha cone in the canal. Place the needle into the canal all the way to the apex. Turn the plunger slowly and withdraw the needle as the root canal and chamber are filled with paste. Gutta percha points may also be used to aid in condensation and complete obturation as desired. A firm base should be placed over the fill, such as zinc phosphate cement. Then a final restoration material of choice is placed.

The L.V.V.E. Syringe should be cleaned promptly, before the paste sets. Use a cleaner such as orange solvent. A 3/8" inch brush is provided to clean the syringe cylinder chamber. A pipe cleaner is used to Clean the hub orifice. A tooth brush may also be useful to clean the threads of the plunger. Dismantle the L.V.V.E. Syringe Before sterilizing by any standard method.

Radiolucent Mouth Prop for Dogs and Cats
- Anatomically designed to provide secure, open mouth
- Use for anesthesia, radiography, oral surgery, and dentistry
- No moving parts, use if canines are absent
- Ultrasound, heat, or cold sterilize
- SMALL size for cats and smaller dogs, LARGE size for medium to large dogs
NOTICE: Veterinarians have used spring-loaded mouth "gags" in cats and dogs for many years. However, the spring-loaded devices are no longer recommended. A study published in THE VETERINARY JOURNAL (2014) showed that the spring-loaded "gags" generating constant force contributes to bulging of the soft tissues between the mandible and the tympanic bulla in cats. This force leads to the compression of the maxillary arteries as they course through the osseous structures. In cats the maxillary arteries are the main source of blood supply to the retinae and brain.
Reduction of the blood flow can result in temporary or permanent blindness and neurologic abnormalities. Spring-loaded "gags" constant force can also cause jaw muscle strain and injury to the temporomandibular joints.
It is recommended to use "static" mouth props such as the WEDGE. Be sure to not open the jaw to its maximum to avoid muscle strain and temporomandibular joint injury.
The WEDGE® is a one-piece, radiolucent mouth prop. The patented, anatomic design holds the carnivore mouth open during anesthesia by securely engaging the premolars and molars.
- Replaces the metal "gag" which catches whiskers and gloves on springs and slides.
- Has no grommets to be lost, permitting metal to enamel contact.
- Can be used if the canines are broken or absent.
- Can be used on either side of the mouth and switched quickly.
- Radiolucency facilitates clear open-mouth radiography.
- May be ultrasounded and heat or cold sterilized.
- Has a hole provided for attachment of a safety lanyard if desired.
- Is useful during anesthesia, intubation, oral examination, oral surgery, dental procedures, and radiographic examination.
Developed and patented by Dr. John L. Scheels, dental consultant to the Milwaukee County Zoo, Adjunct Assistant Professor, University of Wisconsin-Madison School of Veterinary Medicine.
"The (Scheels) Veterinary mouth prop's biggest asset is its simplicity - open the mouth and stick it in!...it does not interfere with radiographic detail, can be ultrasounded, and autoclaved...can be used for dental and oral surgery procedures...is positioned within the mouth, unlike the spring loaded (extra-oral) devices which can be in the way of the operator and interfere with positioning the patient..."
