FAQs
What is the McFarlane 4/5 scaler used for?
It removes supragingival calculus and staining during scaling and routine hygiene work, with two mirrored ends covering opposing tooth surfaces.
Do I need to sharpen it, and how often?
Like all hand scalers it works best kept sharp. Sharpening frequency depends on caseload; many clinics touch up edges at each sterilisation cycle and replace instruments once the blade profile is lost.
Why choose a silicone handle?
A moulded silicone handle is wider and lighter than a solid steel one, so it takes less pinch force to control the instrument. Across a full day of appointments that means noticeably less hand fatigue, and the textured surface keeps its grip when wet or gloved.
What material is this instrument made from?
The working ends are hardened Japanese-standard J2 stainless steel, chosen so the scaling edge survives repeated autoclave cycles, set into a moulded silicone handle. Both are fully autoclavable.
