Calculus is a white-brownish layer with various levels of stiffness, which accumulates on teeth and is formed by the mineralization of dental plaque.~Thus, maintaining oral hygiene and adhering to maintenance programs keep low levels of plaque and calculus.~The electromagnetic field is known for bone healing by lessening osteoclast activity, improving osteoid formation, and stimulating angiogenesis. Furthermore, the electromagnetic field has an antimicrobial effect.~Electric toothbrushes have shown a statistical reduction in plaque accumulation and gingival inflammation.~Previous studies have shown that Silk'n Toothwave results in less plaque accumulation and calculus formation, in addition to stain removal and teeth whitening.~Study aim: to asses the effect of the electromagnetic field in a tooth brush (Silk'n Toothwave) on calculus accumulation and gingival parameters.
to evaluate the influence of radiofrequency based toothbrush (Silk'n toothwave)on the accumulation of the calculus
