It features moderate hardness, excellent toughness, corrosion resistance and high temperature resistance. Repeated sterilization is available, not easy to deform or fracture.1.3 Structural FeaturesInstrument Name: C+ File / Explorer File / C-Type FileInstrument Type: Hand endodontic file for calcified canal negotiationCore Structure: Pyramid ultra-hard tip, flexible shank; high mirror polished surface; square section for anti-deformation; ISO color-coded handle with rubber stop position for accurate working length marking.1.4 Product AdvantagesPyramid tip with strong penetration to break calcified dentin and locate canal orifices quickly.3mm reinforced tip design, balanced hardness and flexibility, suitable for curved and complex canals.Smooth polished surface, low friction and excellent debris removal.Radiopaque design for clear X-ray positioning and working length measurement.High anti-deformation square structure to avoid excessive cutting and improve safety.Two optional lengths to meet clinical needs of anterior and posterior teeth.1.5 Main UsesInitial negotiation and opening for calcified, blocked and obliterated root canals.Root canal retreatment and secondary preparation for residual filling canals.Exploration of narrow fine canals and establishment of glide path.Treatment of molars with curved and severely calcified apical segments.1.6 Operation MethodCheck files for deformation, rust or damage before use.Lubricate with EDTA for softening calcified tissue.Operate with slight rotation and gentle insertion; withdraw immediately when resistance occurs.Operate step by step, skip sizes is prohibited.Pre-bend properly for curved canals to reduce perforation risk.1.7 Sterilization & StorageSupport autoclave sterilization below 126℃ for repeated use.Clean thoroughly by ultrasonic washing after use, then dry and sterilize.Discard damaged, bent or corroded files in time.Store in dry, ventilated environment with humidity ≤80%, avoid extrusion and direct sunlight.1.8 Clinical PerformanceIdeal for molars with curved and calcified apical segments when ultrasonic tools are limited.Clinical Data:K-file combined with EDTA: 50.4% success rateC+ File combined with EDTA: 83.8% high success rate with fewer complications.Hard tip + flexible shank design reduces file separation, ledge and root perforation effectively.1.9 Clinical CaseSeverely Calcified Curved Molar RetreatmentThe mandibular molar presented complete apical obliteration.#10 C+ File (21mm) combined with EDTA was used for gradual negotiation.The root canal pathway was established successfully.Complete obturation with no postoperative pain or apical lesions.2. Dental Stainless Steel D-FINDERS Files(Calcified Curved Root Canal Hand Files, Hand Lifting & Press Operation)2.1 Specifications & Package StandardCommon Sizes: #06, #08, #10, #15Length: 21mm, 25mm, 28mm, 31mmPacking: 6 pcs/boUniversal Shipping StandardSingle box: 10×6×2cm, Gross Weight: 0.065kg100 boxes: 40×30×20cm, Gross Weight: 0.68kg500 boxes: 50×40×30cm, Gross Weight: 3.4kg2.2 MaterialMedical-grade high-toughness stainless steel, high temperature and corrosion resistant.Durable after repeated autoclaving, no rust or aging.2.3 Structural FeaturesInstrument Name: D-FINDERS File / D-Type FileInstrument Type: Special hand file for narrow & calcified canal negotiationCore Structure: Unique D-shaped cross-section with 8-thread design; high strength and toughness; reduced cutting power with smooth round tip.Core Purpose: Negotiation of narrow, calcified, curved and malformed root canals, debris cleaning and apical pathway establishment.Operation: Vertical lifting movement only, rotation angle ≤30°.Application: Dental clinic, pet hospital, laboratory and medical institution for complex root canal treatment.2.4 Product AdvantagesD-shaped section improves file strength and fracture resistance by 1.5 times than ordinary files.Low cutting design prevents root perforation, ledge and canal morphological damage.Weak point penetration principle, safe negotiation without aggressive cutting.Large chip removal space, anti-jamming for blocked narrow canals.High flexibility, high temperature resistance and stable disinfection performance.2.5 Main UsesFor exploration, negotiation and basic shaping of narrow, calcified and curved root canals.2.6 Operation MethodOnly vertical up-and-down lifting movement, forced rotation is forbidden.Penetrate calcified areas slowly with slight movement under resistance.Pre-bend files to fit curved canals for better accessibility.After reaching the apical area, use RT Files or flexible files for final canal preparation.2.7 Safety FeaturesMore than 30% of root canals have calcification and curvature clinically.D-FINDERS avoids over-cutting and maintains original canal morphology.Clear tactile feedback, easy operation for beginners.2.8 PrecautionsHand use only, do not connect to rotary handpiece.Inspect before each use, discard defective files immediately.Autoclave below 126℃ after thorough cleaning.Avoid long-term stress and violent bending to prevent metal fatigue.2.9 Clinical CaseCurved Narrow Anterior Canal NegotiationPersistent apical inflammation with mid-canal calcification.Pre-bent D-FINDERS File operated by vertical lifting.Calcified area penetrated safely, complete three-dimensional obturation with inflammation eliminated.2.10 Difference Between K Files & D-FINDERS FilesOrdinary K Files: Strong cutting force, easy deformation and jamming in curved or calcified canals, high risk of perforation.D-FINDERS Files: D-shaped high fracture resistance, low cutting performance, focus on safe negotiation, ideal for complex curved and calcified root canals.3. Comparison of Full Series Endodontic Hand FilesK File: General preparation, square section, for straight & mild curved canalsH File: High cutting force, pull-only operation, for straight canal debris removalR File (Reamer): Sparse thread, rotary cutting for narrow initial glide pathS File (Spreader): Smooth non-cutting tip, for cold gutta-percha lateral condensationP File (Plugger): Blunt tip, for vertical compaction of complex curved canalsC+ File: Hard tip & flexible shank, for severe calcification and root retreatmentD-FINDERS File: D-type anti-break design, safe negotiation for narrow curved calcified canals
