Introduction

The formation and removal of dental calculus poses a significant problem for many adult patients and dental professionals.^1,2  Clinical and epidemiological surveys confirm significant calculus formation in a broad portion of the population with prevalence approaching 90%.³  In addition to the obvious cosmetic implications (Figure 1), supragingival calculus may impede normal hygiene (particularly flossing), and in excessive quantities, may contribute to gingival recession.³ 

Subgingival calculus is more commonly associated with chronic periodontal diseases, although debate continues as to whether these deposits are the cause, promoter, or result of the inflammatory processes.¹  Once formed, calculus removal can only readily be accomplished through time-consuming scaling often in areas that are difficult to visualize and/or access.
