Citoject Syringe for Periodontal Ligament Anesthetic Delivery

The Citoject Syringe from Peak Surgicals is a reusable stainless steel dental anesthetic syringe designed for controlled intraligamental, periodontal ligament, intraseptal, and localized intraoral anesthetic delivery during restorative dentistry, endodontic therapy, tooth extraction, pediatric dentistry, periodontal treatment, crown preparation, and minor oral surgery. Each syringe is priced at $66.00 and features a pen-style body, cartridge chamber, side viewing window, needle hub, internal plunger rod, pressure-regulating drive mechanism, lever activation control, spring-supported delivery action, and protective sleeve profile for precise placement at the periodontal ligament space. Dentists, oral surgeons, endodontists, pediatric dentists, periodontists, general dental practitioners, hospital dental departments, outpatient clinics, ambulatory oral surgery centers, and dental procurement teams use this syringe when tooth-specific anesthesia is required without broad soft tissue numbness. The instrument supports standard dental anesthetic cartridges and fine-gauge dental needles, allowing the clinician to deliver small volumes of local anesthetic into the periodontal ligament area adjacent to the selected tooth while maintaining controlled hand position and direct tactile feedback.

Pen-Style Barrel, Cartridge Chamber, Side Window, Needle Hub, and Lever Control

The Citoject design uses a pen-style barrel so the clinician can hold the syringe close to the operative site with a stable writing-grip position. The cartridge chamber houses the standard dental anesthetic cartridge, while the side viewing window allows the operator to monitor cartridge placement and remaining anesthetic volume during clinical use. The needle hub supports attachment of a fine-gauge dental needle so the tip can be positioned into the periodontal ligament space at the mesial or distal line angle of the target tooth. The internal plunger rod advances the cartridge piston when the lever control is activated. This lever-driven mechanism converts small hand movement into controlled anesthetic expression, reducing sudden bolus delivery into dense periodontal tissue. The pressure-regulating action is central to intraligamental injection because the ligament space offers high resistance compared with loose mucosal infiltration sites. The sleeve and clip-style body stabilize the hand while the operator maintains needle angle, insertion depth, and gradual delivery.

PDL Injection, Endodontic Anesthesia, Restorative Dentistry, Extraction, and Pediatric Workflow

During periodontal ligament injection, the Citoject Syringe is positioned with the needle bevel directed into the gingival sulcus and advanced into the ligament space alongside the tooth root. In endodontic therapy, the instrument supports supplemental anesthesia for mandibular molars, inflamed pulps, failed block anesthesia, and tooth-specific pulpal control before access cavity preparation, canal negotiation, shaping, and obturation. During restorative dentistry, it provides localized anesthesia for crown preparation, deep caries excavation, matrix placement, and operative work on a single tooth. In extraction workflow, the syringe supports supplemental periodontal anesthesia before luxation, elevator use, root movement, and forceps delivery. In pediatric dentistry, controlled small-volume delivery is valuable when broad lip, tongue, or cheek anesthesia is not desired after treatment. During periodontal procedures, the instrument supports localized anesthesia around selected teeth before scaling, root planing, gingival manipulation, or minor surgical access. Its compact body improves posterior access where conventional aspirating syringes can obstruct the working view.

Standard Dental Cartridge Compatibility and Fine-Gauge Needle Delivery

The Citoject Syringe is built around standard dental anesthetic cartridge use, allowing dental teams to integrate it into existing local anesthesia workflows without changing cartridge inventory. The cartridge chamber supports controlled seating of the carpule, while the plunger rod engages the rubber piston for progressive anesthetic advancement. Fine-gauge needle compatibility supports accurate periodontal ligament placement at the cervical region of the selected tooth. Smaller needle diameter is useful in PDL anesthesia because access is made through the sulcus into a narrow ligament space rather than through broad mucosal tissue. The side window provides visual confirmation of cartridge position and volume status during repeated tooth-specific injections. The lever mechanism allows the clinician to deliver limited anesthetic increments while maintaining the needle in the same periodontal position. This design is clinically different from a conventional aspirating syringe, which is optimized for nerve block and infiltration delivery. The Citoject format is selected when the operator needs compact access, controlled pressure, and localized anesthetic expression.

Stainless Steel Construction, Reprocessing, Finish Integrity, and Procurement Documentation

Stainless steel construction gives the Citoject Syringe the rigidity, corrosion resistance, and reusable durability required for repeated dental clinic and oral surgery use. A cartridge syringe must retain cartridge chamber alignment, plunger rod movement, lever response, needle hub fit, side window integrity, and smooth exterior surfaces because distortion can affect anesthetic delivery control. The metal body supports repeated cleaning and clinical reprocessing while maintaining the tactile feel required for periodontal ligament injection. After use, the needle is removed, the cartridge is discarded according to clinic protocol, the chamber is opened, the plunger mechanism is cleaned, and the exterior body is wiped and inspected before sterilization workflow. Hinged and lever-contact areas are brushed carefully so dried anesthetic residue does not affect movement. CE marking, ISO-13485 certification, and FDA compliance support hospital purchasing, dental clinic procurement, distributor documentation, and international tender files. Reusable format, and standard cartridge compatibility support procurement planning for dental anesthesia instrument trays.
