Citoject Dental Intraligamental Syringe for 1.8/2.1 mL PDL Anesthesia

Citoject Dental Intraligamental, SKU PS-OT-0056, Model PS-701, is a dental intraligamental syringe manufactured from German stainless steel for controlled local anesthetic delivery into the periodontal ligament space. The available cartridge options are 1.8 ML, 2.1 ML, and Both Sizes, supporting dental practices that use standard local anesthetic cartridges across endodontic, restorative, periodontal, extraction, and operative dentistry workflows. The instrument is used for periodontal ligament anesthesia, single-tooth anesthesia, supplemental anesthesia after incomplete inferior alveolar block, endodontic access anesthesia, crown preparation anesthesia, subgingival restorative procedures, scaling and root planing support, and pre-extraction anesthetic reinforcement. Its lever-controlled injection mechanism advances the plunger in measured increments, while the cartridge barrel, visible cartridge window, needle hub, pivoted lever, and handle body support controlled placement and delivery. This syringe is used by dental surgeons, endodontists, periodontists, general dentists, pediatric dentists, hospital dental departments, and procurement teams maintaining reusable anesthesia instruments for clinical dental operatories.

Lever-Controlled Cartridge Injection Mechanism

The instrument works through a lever-driven plunger system that converts finger pressure into controlled cartridge advancement. The long handle body houses the anesthetic cartridge, while the visible window allows the operator to confirm cartridge position before clinical use. The anterior metal assembly stabilizes the needle hub and directs the working end toward the periodontal ligament injection site. The pivoted lever acts as the control feature, moving the internal plunger forward in small increments instead of delivering a large bolus from a conventional thumb-ring syringe. This mechanism supports slow anesthetic deposition in the periodontal ligament space where high-pressure injection requires tactile control. The angled front section helps the operator align the needle along the gingival sulcus and interproximal approach without excessive wrist rotation. The handle length supports pen-style or modified palm control depending on operator preference. The screw connection at the cartridge end secures the assembly during repeated injection cycles. The design is selected when the clinician needs localized anesthetic delivery around a single tooth rather than broad nerve block coverage.

Periodontal Ligament Anesthesia Workflow

In clinical sequence, Citoject Dental Intraligamental is prepared after cartridge loading, needle attachment, visual cartridge inspection, and confirmation of smooth plunger movement. For periodontal ligament anesthesia, the needle is positioned at the gingival sulcus and advanced toward the periodontal ligament space adjacent to the selected tooth. The operator depresses the lever gradually, delivering anesthetic under controlled pressure into mesial, distal, buccal, or lingual sites according to the treatment plan. During endodontic access, it is used as supplemental anesthesia when pulpal response persists after regional block or infiltration. In restorative dentistry, it supports single-tooth anesthesia for crown preparation, deep caries excavation, matrix placement, and subgingival margin work. During extraction, the syringe can reinforce local anesthesia before elevator use and forceps delivery. In periodontal therapy, it supports localized anesthetic control during scaling, root planing, and subgingival instrumentation. The instrument is suited to dental clinics, hospital dental units, oral surgery rooms, and specialty operatories requiring controlled cartridge-based local anesthetic delivery.

1.8 ML and 2.1 ML Cartridge Selection

The 1.8 ML option is selected for practices using standard dental anesthetic cartridges commonly supplied for restorative, endodontic, periodontal, and extraction procedures. This size fits workflows where single-tooth anesthesia, supplemental periodontal ligament injection, and chairside cartridge exchange are routine. The 2.1 ML option supports users working with larger cartridge formats or regional supply systems that use higher-volume dental anesthetic cartridges. The Both Sizes option is selected by clinics, hospitals, and distributors that need compatibility across different cartridge inventories without maintaining separate syringe types. The cartridge barrel provides the housing function, keeping the anesthetic carpule aligned with the plunger path. The plunger provides forward pressure, the lever controls incremental advancement, the needle hub provides delivery alignment, and the window supports visual confirmation before injection. Citoject Dental Intraligamental is therefore chosen according to cartridge stock, treatment volume, and anesthesia protocol. In procurement planning, the two-capacity availability supports mixed clinical departments and international supply chains using different local anesthetic cartridge standards.

Reusable Steel Construction and Compliance Records

German stainless steel provides the structural stability required for repeated cartridge loading, lever actuation, needle hub control, and clinical reprocessing. The material supports reusable dental instrument workflows where the syringe is cleaned, inspected, packaged, and sterilized between patients according to facility protocol. Satin, dull, and mirror finish options support different operatory and central sterile preferences; reduced-glare finishes improve visibility under chairside lighting, while mirror surfaces assist rapid visual inspection after cleaning. Reprocessing focuses on the cartridge chamber, plunger contact area, lever pivot, needle hub, screw connection, and handle window because anesthetic residue and biological debris can collect around these surfaces. The Class I classification reflects a reusable manual dental instrument with mechanical injection control. CE marking and ISO 13485 documentation support regulated purchasing records for dental clinics, hospitals, distributors, and procurement teams. FDA compliance information supports medical device procurement files for regulated healthcare markets. The one-year warranty, MOQ of one piece, OEM availability, carton box packing, and return or replacement after-sale service support clinic replenishment and distributor inventory workflows.

How does Citoject Dental Intraligamental differ from a conventional aspirating dental syringe?
Citoject Dental Intraligamental is designed for periodontal ligament injection, while a conventional aspirating dental syringe is commonly used for infiltration and nerve block anesthesia. The conventional syringe uses a thumb ring and plunger rod to deliver a larger cartridge volume through direct manual pressure. This instrument uses a lever-controlled mechanism that advances anesthetic in small increments for localized single-tooth anesthesia. Its cartridge barrel, window, lever, and needle hub support controlled delivery into the periodontal ligament space. A conventional aspirating syringe offers broader injection utility, but it does not provide the same incremental lever control for high-pressure intraligamental deposition. Citoject Dental Intraligamental is selected when the clinician needs supplemental anesthesia around a specific tooth.

How are the 1.8 ML and 2.1 ML options selected?
The 1.8 ML option is selected for clinics using standard dental local anesthetic cartridges in routine restorative, endodontic, periodontal, and extraction procedures. The 2.1 ML option is selected when the practice uses larger dental cartridge formats in its anesthesia workflow. The Both Sizes option is useful for departments that maintain mixed cartridge inventory or serve multiple operatories with different anesthetic stock. For periodontal ligament anesthesia, cartridge selection is guided by the available anesthetic cartridge system rather than the injection site alone. Citoject Dental Intraligamental supports single-tooth anesthesia, supplemental block reinforcement, and localized operative dentistry procedures. Clinics can select the configuration that matches their existing dental cartridge supply and sterilization setup.

How do CE, ISO 13485, and FDA documentation support procurement?
CE marking supports product conformity documentation for dental clinics, hospitals, and distributor purchasing teams. ISO 13485 indicates that the manufacturing system follows medical device quality management and traceability requirements. FDA compliance information supports procurement records for regulated healthcare supply channels. Citoject Dental Intraligamental can be entered into anesthesia instrument purchasing files with recognized compliance references. These records support vendor approval, tender documentation, and repeat ordering for operating room and dental department supply teams. International buyers can use the same documentation when comparing reusable dental intraligamental syringes across procurement sources.

How is the lever control used during intraligamental injection?
The lever is the main control feature used to advance the plunger against the anesthetic cartridge. After the needle is positioned at the periodontal ligament space, the operator depresses the lever gradually to deliver small increments of solution. This controlled advancement helps manage injection pressure during localized periodontal ligament anesthesia. The pivoted lever transfers finger pressure to the plunger while the cartridge barrel keeps the carpule aligned. The visible window allows the clinician to monitor cartridge placement during setup and use. Citoject Dental Intraligamental relies on this lever mechanism for controlled delivery rather than direct thumb-ring compression.

What should clinics and distributors know about sterilization and ordering?
This product is reusable and suitable for standard dental instrument reprocessing workflows. Cleaning focuses on the cartridge chamber, lever pivot, needle hub, screw connection, plunger contact area, and handle window before sterilization. The instrument is dried and inspected before packaging in a pouch or cassette for steam autoclave processing. Clinics can order one piece because the MOQ is one piece. OEM availability supports distributors requiring branded or customized supply programs. Citoject Dental Intraligamental is supplied with one-year warranty coverage and return or replacement after-sale support for clinic replenishment and distributor stock planning.
