WHO/CPITN Probe Color for 3.5-11.5mm Periodontal Screening

WHO/CPITN Probe Color, SKU PS-D-048, is a reusable dental periodontal screening probe made from German stainless steel for CPITN assessment, PSR-style periodontal screening, gingival bleeding evaluation, calculus detection, peri-implant mucosal review, and routine dental examination. The instrument uses a rounded ball-tip working end with black reference markings at 3.5mm, 5.5mm, 8.5mm, and 11.5mm on a 10mm lightweight handle for rapid sextant-based screening and depth classification. The right-angle shank positions the marked tip into posterior molar, premolar, lingual, distal, interproximal, crown-margin, bridge-abutment, orthodontic band, implant-adjacent, and veterinary oral sites while keeping the clinician’s hand outside the occlusal field. The color-coded markings support chairside reading during periodontal triage, hygiene recall, supportive periodontal therapy, pre-extraction dental clearance, restorative review, and implant maintenance appointments. Periodontists, general dentists, dental hygienists, restorative clinicians, oral surgery teams, orthodontic departments, hospital dental units, teaching clinics, veterinary dental practices, distributors, and procurement offices use this probe in reusable diagnostic tray setups.

Ball-Tip Probe Geometry and Right-Angle Access

The WHO/CPITN Probe Color uses a fixed right-angle shank to bring the marked working end into posterior and interproximal sites while the handle remains clear of cheeks, tongue, mirror, and suction. The rounded terminal ball provides a controlled leading surface for sulcus entry and root-surface contact during periodontal screening. This ball-tip design supports tactile detection of calculus deposits, restoration overhangs, and pocket bases while reducing sharp-point engagement compared with a conventional explorer. The black reference bands are positioned for direct visual reading at the gingival margin during sextant assessment. The long slender shank improves access to distal molars, lingual mandibular surfaces, maxillary posterior areas, bridge connectors, crown contours, orthodontic bands, and implant-supported restorations. A 10mm handle gives compact fingertip control for walking the tip around the sulcus with light, repeatable pressure. There is no ratchet, spring, lock, pivot, or box joint because the working action depends on manual insertion pressure, tactile response, fixed shank angulation, and visual interpretation of the band position.

CPITN Screening and Periodontal Examination Workflow

During CPITN or PSR-style periodontal screening, the WHO/CPITN Probe Color is introduced after visual soft tissue inspection, plaque review, and supragingival calculus assessment. The clinician places the ball tip parallel to the tooth surface and walks it around each sextant to record bleeding response, calculus presence, restoration overhangs, and screening depth. The right-angle form is useful in posterior sextants where straight probes can obstruct the mirror line or require wrist deviation. Hygienists use the instrument during recall appointments to identify screening codes before full charting is assigned. Periodontists use it for initial triage, supportive therapy review, and monitoring of treated sites. Restorative clinicians apply the ball tip around subgingival crown margins, bridge abutments, cement remnants, and implant-supported prosthetic contours where tissue response must be assessed. Oral surgery teams use the probe during pre-extraction clearance and postoperative soft tissue review. Veterinary dental clinicians use the same angled access during canine and feline posterior oral assessment where jaw opening, cheek position, and visibility restrict straight instrument movement.

3.5mm, 5.5mm, 8.5mm, and 11.5mm Band Use

The 3.5mm band is used during shallow sulcus screening, preventive recall, and baseline gingival review when the clinician needs rapid classification rather than full millimeter charting. The 5.5mm reference identifies pocket depth that requires closer periodontal evaluation, localized debridement planning, bleeding notation, or transition to complete periodontal charting. The 8.5mm band supports deeper screening around molars, furcation-adjacent areas, root concavities, bridge abutments, implant-supported posterior restorations, and advanced maintenance cases. The 11.5mm reference is used when severe periodontal pocketing requires comprehensive charting, periodontal surgery consultation, extraction assessment, or referral documentation. The ball tip remains active throughout the screening sequence because it permits tactile contact while the clinician walks the sulcus. The right-angle shank is selected for posterior access, lingual surfaces, distal molars, orthodontic appliance margins, and peri-implant mucosa. This marking sequence is selected when the department wants CPITN-style threshold recognition instead of Williams, UNC, or CP-12 continuous millimeter recording.

German Stainless Steel Reprocessing and Procurement Fit

German stainless steel construction gives the WHO/CPITN Probe Color the rigidity required for controlled probing while preserving the right-angle shank and rounded terminal end through repeated clinical use. The smooth working surface supports inspection after cleaning, and the black markings remain visually distinct under operatory lighting during periodontal screening. Reprocessing follows standard dental instrument workflow: point-of-use debris removal, careful cleaning around the ball tip and marked shaft, ultrasonic cleaning when included in facility protocol, rinsing, drying, inspection of the markings and terminal end, packaging, and steam autoclave sterilization. A single-piece reusable metal body simplifies tray counts because there are no detachable measuring sleeves, plastic inserts, or disposable tips. CE marking supports international medical device procurement, and ISO 13485 certification reflects manufacturing controls expected by clinics, hospitals, dental schools, distributors, and institutional buyers. FDA-compliant procurement support helps United States customers maintain reusable dental hand instrument records. The product supports single-piece replacement, multi-chair replenishment, custom diagnostic sets, OEM programs, order tracking, return assistance, and procurement documentation for professional dental and veterinary supply channels.

How does this differ from a Williams periodontal probe?
WHO/CPITN Probe Color is designed for screening and sextant-based periodontal assessment, while a Williams periodontal probe is designed for detailed pocket charting. A Williams probe uses selected millimeter markings such as 1mm, 2mm, 3mm, 5mm, 7mm, 8mm, 9mm, and 10mm for site-specific recordings. This instrument uses CPITN-style black bands at 3.5mm, 5.5mm, 8.5mm, and 11.5mm for rapid depth classification. The ball tip changes the contact profile by allowing rounded sulcus entry and tactile calculus detection. Williams probes are selected when six-point full-mouth pocket measurements are required. WHO/CPITN Probe Color is selected when the appointment requires periodontal screening before complete charting or treatment planning.

How should the 3.5mm, 5.5mm, 8.5mm, and 11.5mm bands be selected?
WHO/CPITN Probe Color uses the 3.5mm band for shallow sulcus screening and routine periodontal recall. The 5.5mm reference indicates a deeper finding that requires closer evaluation, localized therapy planning, or full charting. The 8.5mm band is used around molars, root concavities, furcation-adjacent contours, bridge abutments, and implant-supported posterior restorations where advanced pocketing must be classified. The 11.5mm reference supports severe periodontal screening before periodontal surgery consultation, extraction assessment, or referral. The ball tip is used throughout the sequence because it contacts the sulcus and root surface with a rounded terminal profile. Selection is based on sextant findings, pocket depth, tissue response, target anatomy, disease stage, and department screening protocol.

How do CE, ISO 13485, and FDA procurement requirements apply?
WHO/CPITN Probe Color is supplied for professional dental purchasing where reusable hand instrument documentation is required. CE marking supports international procurement records for clinics, hospitals, dental schools, distributors, and institutional buyers. ISO 13485 certification reflects manufacturing controls used in regulated medical device supply. FDA-compliant procurement support helps United States buyers maintain vendor files and reusable dental instrument records. These references support tender preparation, distributor onboarding, clinic audits, product file review, and multi-location purchasing approval. The instrument remains a non-powered dental periodontal screening probe for professional chairside examination.

How are the ball tip, right-angle shank, and markings controlled during use?
The control feature on WHO/CPITN Probe Color is the fixed right-angle shank combined with a rounded ball tip and black reference bands. The clinician holds the 10mm handle with light fingertip pressure and walks the terminal end around the gingival sulcus. The shank keeps the hand outside the posterior field while the marked tip enters distal, lingual, crown-adjacent, and peri-implant sites. The ball tip contacts the root surface and helps detect calculus, restoration ledges, and pocket bases. The black band is read at the gingival margin before the tip is moved to the next site. There is no ratchet, spring, lock, pivot, or box joint because the probe depends on manual pressure, tactile feedback, and visual band interpretation.

How should clinics and distributors manage sterilization and supply?
WHO/CPITN Probe Color is a reusable German stainless steel dental instrument suitable for standard clinical tray reprocessing. After use, staff remove visible debris, clean the ball tip and marked shaft carefully, rinse, dry, inspect the black bands and right-angle shank, package the instrument, and steam autoclave it according to facility protocol. The one-piece metal construction supports repeated turnover in periodontal, hygiene, restorative, implant maintenance, oral surgery, orthodontic, teaching, and veterinary dental trays. Hospitals and teaching clinics can stock the same screening pattern across departments to standardize CPITN and PSR-style evaluations. Distributors can order single pieces or include the item in custom diagnostic kits for professional buyers. The $11.00 USD price supports replacement ordering, department replenishment, and multi-chair clinic inventory planning.
