Researchers have recently found that a slim scaler tip design causes less tooth substance loss compared to a wider scaler design, as published by the BMC Oral Health Journal.

The influence of scaler tip design on root surface roughness, tooth substance loss, and patients’ pain perception is investigated.

This article was divided into the following parts: Part 1 Surface roughness and substance loss: an in vitro study, which involves intact extracted teeth sectioned and treated using a piezoelectric ultrasonic device with a conventional scaler tip and a Perio Slim (PS) scaler tip. Part 2 Pain Perception: a clinical study, which was a split-mouth study design including 30 participants with gingivitis and/or mild chronic periodontitis; treated with supra-gingival scaling from teeth #13 to #23. Subjects were randomized to group A or group B. Group A was treated first with PS scaler tips, whereas group B was treated first with conventional scaler tips.

The findings were;
--In vitro study: both scaler tips caused a significant reduction in root substance roughness after scaling, but no significant difference between the two scaler tips was observed.

--The PS scaler tip caused statistically significantly less root substance loss when the initial thickness of the tooth was <?1000 µm.

--Clinical study: the participants reported significantly lesser pain scores during scaling using the PS scaler tip (median: 3) than when using the conventional scaler tip.

In conclusion, in the in vitro study, using a slim scaler tip design causes less tooth substance loss compared to a wider scaler tip design. In the clinical study, less pain was observed compared to a wide (conventional) scaler tip design.
