NES-1915

Fig. 3-7
Heavy, burnished calculus on buccal or lingual root surfaces often resists standard curettes. The NES-1915 Fig. 3-7 Hirschfeld file is built to address that resistance. Its series of parallel cutting edges engage the deposit directly, fracturing it into removable fragments with short, controlled pull strokes. The buccal-lingual orientation matches the common location of tenacious ledges, allowing the clinician to stay parallel to the root and avoid unnecessary cementum removal.
Crafted from durable stainless steel, the file maintains edge integrity across multiple sterilization cycles. The handle design encourages a firm yet relaxed grip that transmits clear tactile signals when the calculus begins to yield. This feedback helps the operator limit strokes to the deposit itself rather than the surrounding root surface.
Beyond active debridement, the instrument can act as a diagnostic instrument when used with light pressure to map the extent of remaining calculus or confirm surface smoothness after initial breakdown. Next Edge Surgical LLC includes the NES-1915 in its periodontal instrument range for hygienists and periodontists who regularly encounter stubborn deposits that require a specialized filing approach.
