Abstract

Introduction

Calculus can accommodate teeth and prosthetic restorations when the patient's oral hygiene is poor. Hardened calculus cannot be removed by patients, it needs professional cleaning using ultrasonic scaler or hand instrument. Solutions dissolving and preventing accumulation of dental calculus may help to keep dentures clean. The aim of this investigation was to examine the effect of Periogen on dental calculus in vitro.

Materials and methods

Calculus was collected via scaling from patients during a routine dental checkup. The samples were stored in carbamide peroxide solution (5%) for 24 hours, then rinsed and stored in distilled water. First, the Ca2+ content of the calculus was determined by photometric method after treating with cc. hydrochloric acid solution for 1 hour. The calculus samples were put in Periogen solution, prepared according to manufacturer's instruction for 16 hours, then crushed and put in Periogen solution with the same concentrate for 4.5 hours. The Ca2+ dissolved from calculus was measured using same photometric method.

Results

Calculus samples contained 26 mg/100 mg Ca2+, which is similar to dentin (27–28 mg/100 mg) and to enamel (36 mg/100 mg). The Ca2+ dissolved from calculus after treating with cc. hydrochloric acid for 1 hour was considered 100%. Ca2+ dissolution was 1.5% after 16 hours (0.09%/h) and 5.45% (1.21%/h) for the next 4.5 hours after pulverizing the sample. This showed Periogen Ca2+ dissolution was 385 µg/100 mg after 16 hours direct contact with the material.

Conclusion

The experiment showed that pulverizing the previously hard calculus was done easily after soaking it in Periogen. The ability of Periogen to soften the calculus needs to be further investigated.
