Periodontal Dental Instrument – Available in Hollow Handle Ø 8mm, Ø 9.5mm Solid Handle Ø 6mm – NES-1428

Columbia 4L/4R
Universal curettes remain a cornerstone of periodontal therapy, and the NES-1428 Columbia 4L/4R delivers the classic design clinicians trust. Both ends feature a curved, rounded toe and two cutting edges, allowing the instrument to adapt to multiple tooth surfaces without requiring a large collection of area-specific tools. The 4L/4R angulation is particularly effective for posterior teeth, giving reliable access to buccal, lingual, and proximal root surfaces.
Forged from surgical-grade stainless steel, the blades hold a sharp edge through repeated sharpening and autoclave cycles. The handle options—hollow Ø 8 mm, Ø 9.5 mm, or solid Ø 6 mm—let operators choose the diameter that best reduces fatigue during full-mouth debridement. Tactile sensitivity remains high, so the clinician can feel the transition from calculus to clean root structure.
This dual-ended curette supports both supra- and subgingival scaling in moderate pockets. Next Edge Surgical LLC offers the NES-1428 as a versatile diagnostic instrument that also performs therapeutic root planing, helping confirm deposit location while actively removing it. A practical, time-tested choice for everyday periodontal care.
