Abstract A double‐blind, cross‐over study was carried out to assess the anti‐calculus effectiveness of a pyrophosphate containing cleaning gel. 2 groups of 30 heavy calculus formers were followed up comparing conventional clinical scoring systems (Volpe‐Manhold‐Index and Marginal‐Line‐Calculus‐index) and micromorphologic SEM criteria of calculus formation and inhibition. The results indicated that after a 3‐month period, there was a significant reduction of calculus formation compared to a placebo gel. The proposed SEM calculus index (SEMCI) objectively reflects the reduction of supragingival calculus formation.
