Background: Calculus is the mineralised matrix of plaque present on the hard and soft tissues of the oral cavity. The breakdown of proteins within dental plaque releases ammonia and carbon dioxide which increases salivary pH and lowers the precipitation constant. Precipitation of the calcium phosphate salts within the plaque facilitates calculus formation. In order to prevent plaque accumulation after oral prophylaxis, chlorhexidine mouthwash is routinely prescribed. However, common side effects of brown staining of the teeth and calculus formation have been seen to occur with frequent use. Aim: The aim of the study was to assess the efficacy of two anti-calculus tootpastes subsequent to chlorhexidine use. Materials and methods: 90 patients with calculus formation were selected for the study and broadly categorised into two groups. Following oral prophylaxis, one group of patients used the anti-tartar toothpaste XTAR-TM (ICPA, India) with the active ingredient potassium pyrophosphate while the other used Colgate Total (Colgate-Palmolive) with the active ingredient triclosan. Within this group, the patients were further divided into 3 sub-groups: the first using only the toothpaste, the second using the toothpaste and chlorhexidine mouthwash for a week and the third group that used chlorhexidine for two weeks along with the toothpaste. The calculus accumulation on the lower anteriors was recorded preoperatively and post-operatively using the Volpe-Manhold index. All the indices and the pockets were measured from baseline to the end of 2 weeks. Results:Accessing the two week statistical data we were able to find a good prognosis in use of the potassium pyrophosphate tooth paste in comparing the triclosin tooth paste. After the use of chlorhexidine there was a little positivity at the end of second week. Among that group potassium pyrophosphate had better prognosis even after the use of chlorhexidine for 1 week Conclusion:Use of Anti- calculus has a good prognosis of periodontium along with the use of the chlorhexidine mouth wash. Effect of triclosin on prevention of calculus is minimal but when used with it has a better action. General oral hygiene maintenance by the candidates is important which act as a main criteria for the plaque formation; better oral hygiene prevent the accumulation of the plaque thereby preventing calculus formation
