The traditional dental hand syringe was first introduced in 1853 and has remained virtually unchanged in over 165 years. The fluid dynamics of the manual syringe make it impossible to consistently regulate the flow rate. As a result, terms like “you’re going to feel a little pinch” have resonated throughout dental clinics for over a century.
- It’s estimated that 75% of the US population fear dental care to some degree, while as many as 50% avoid the dentist altogether.
- Patients perceive the hand syringe as the leading cause of their pain & anxiety. Currently, over 50 million Americans are said to suffer with some degree of dental phobia
- Traditional hand syringes are among the most threatening and least ergonomic instruments used in dentistry. Not only does the syringe look intimidating to the patient, but the locked forearm and thumb delivery is a leading cause of repetitive strain injury to dentists and hygienists. As a result, injections are administered way too quickly, and the frequency of aspirating before injections has dropped to nearly 50%.
- Due to patient discomfort caused by traditional syringe injections, more clinically suitable injection types such as palatal and single tooth (PDL) procedures are replaced with IA blocks, local infiltrations, and conscious sedation.
Give the best injections possible with CALAJECT!
Computer assisted anesthesia delivery with CALAJECT is more comfortable, more accurate, offers better control, and provides more treatment options than a traditional hand syringe.
The CALAJECT system comes pre-programmed with settings for performing regional nerve blocks, infiltrations, palatal, and intraligamentary (single tooth) injections. The anesthetic flow rates are regulated by the built in microprocessor, and aspiration is performed automatically by releasing the foot pedal.
- Computer regulated flow rates ensure an optimal injection experience
- Pen-like grip offers an incomparable ergonomic benefit over traditional injections
- Offers the highest standard of care by allowing for more treatment options
- Standardized injection protocol
- Simple and easy to operate
Computer regulated flow rates ensure an optimal injection experience
With CALAJECT, the delivery flow rates that are taught in dental school are pre-programmed and delivered automatically. There is no guess work. Select your injection program and step on the foot pedal. The anesthetic is dispensed at the optimal flow rate, below the patients’ pain threshold, every single time. To aspirate, simply release the foot pedal.
Pen-like grip provides incomparable ergonomic & tactile control benefits
Because the anesthetic is dispensed automatically by foot pedal operation, CALAJECT is held like pen. You exert no thumb pressure, and your forearm is freed from the muscle strain and tension associated with manual syringe delivery. The pen grip allows for precise, delicate needle placement and allows you to sit in a comfortable ergonomic position while injecting.
Offers the highest standard of care by allowing for more treatment options.
With CALAJECT, injections that were previously avoided due to patient discomfort can be added to your treatment protocol.
- Single tooth anesthesia (STA) injections – Unlike traditional PDL injections, intraligamentary or intrasulcular STA injections with CALAJECT are administered painlessly and reliably. CALAJECT monitors and displays actual injection pressure in the PDL space, allowing clinicians to numb only the tooth (or group of teeth) being worked on. The patient benefit is tremendous, as there is no pain or collateral numbness associated with these injections. The patient leaves the appointment without the lingering 4 hour numbness of the tongue, lips, and face. Once you master the STA technique, you’ll give fewer blocks and have happier patients!
- Palatal injections – With a traditional syringe, palatal injections are the most uncomfortable injections to experience and administer. With CALAJECT’s computer regulated flow rate and tactile pen grip, these injections can now be performed comfortably. Anesthetize five teeth and surrounding tissue with just one injection. Administer a reduced dosage of anesthetic with no risk of intravascular injection. Conduct accurate smile line assessments immediately after the procedure, as there is no collateral numbness affecting the lip or facial muscles.
- Fewer missed blocks – The miss rate for lower block injections with a traditional syringe is between 10-20% due to needle deflection. With CALAJECT, the pen grip allows you to bi-rotationally insert and advance the needle, virtually eliminating missed blocks.
Standardized Injection Protocol
The hallmark of administering a comfortable dental injection is delivering the anesthetic at a slow, controlled rate of flow to prevent tissue tearing and to reduce patient discomfort. Emptying a 1.8 mL cartridge with a manual hand syringe in the recommended 1-2 minute timeframe is a challenging task. In fact, according to widely a published survey, 84% of dentists stated that the average time spent to deposit a full cartridge was less than 20 seconds. The same inconsistencies are reported with regard to manual aspiration before injection. Over 80% of dentists surveyed stated that they “rarely” aspirate before performing IA nerve block or maxillary infiltration injections with a manual hand syringe.
With CALAJECT, injection standardization is guaranteed. The rates of flow are regulated by the microprocessor, and aspiration is performed automatically when you release the foot pedal. No matter if it’s your 1st or 20th injection of the day, the plunger moves at the same, controlled rate every single time. This benefit is particularly important in large, multichair practices where multiple clinicians administer local anesthesia. Where there is wide variability to manual hand syringe technique (and patient comfort), CALAJECT ensures virtually the same injection experience from clinician to clinician.
Easy to operate
CALAJECT operates with standard dental needles and cartridges. The system comes programmed with 3 distinct flow rate settings for STA/Palatal, Infiltrations, and Block injections.
- Select the injection setting of your choosing and depress the foot pedal to initiate plunger advancement.
- Depending on the setting, you can increase/decrease the rate of flow by fully releasing and immediately stepping back down on the foot pedal.
- To aspirate, simply release the foot pedal to initiate retraction.
CALAJECT is powered by a long-lasting lithium batterry, and the small, compact design makes it easy to move within your practice. For complete instructions, please visit our operation & video instructions tab.
Uses Standard Needle Tips
Competing computer controlled injection systems require the use of costly disposable tubing sets for every injection. Calaject operates on standard, monoject needle tips. In addition to the cost savings associated with CALAJECT, there’s the added advantage of standardizing inventory within your practice. Every operatory will be stocked with the same needle tips used with a manual hand syringe.

The most universally feared device in dentistry
The administration of local anesthesia is considered by patients to be the most important aspect of dental treatment. When patients experience a painless injection, they are significantly more satisfied.
CALAJECT sends a clear message to your patients that you are utilizing technology to make their dental experience as comfortable as possible. Once you begin treating your patients with CALAJECT, they won’t even consider going to another practice. And for new patients, nothing differentiates you and the treatment you provide more than word of mouth and your association of providing the most comfortable injections available.
