Comparative evaluation of clinical outcome of indirect pulp treatment with calcium hydroxide, calcium silicate and Er,Cr:YSGG laser in permanent molars.

Background: The aim of the study was to compare preservation of pulp vitality by indirect pulp treatment with calcium hydroxide, calcium silicate based cement (Biodentine) and Er,Cr:YSGG laser in permanent molars.

Materials and methods: 30 patients were selected for this study as per the inclusion and exclusion criteria in the age group of 6-14 years and then randomly allocated to three groups A, B & C. In group A, after caries excavation, calcium hydroxide (Dycal) was placed at the floor. In group B, after caries excavation, calcium silicate based cement (Biodentine) was placed at the floor. In group C, after caries excavation, decontamination of the cavity was done with Er,Cr:YSGG laser. This was followed by placement of permanent restorative material in all the groups. Clinical and radiographic success was monitored at 3, 6 and months. Data analysis was performed using Statistical Package for the Social Science-21 (SPSS-21).

Results: At the end of 9 months, overall success rate of indirect pulp was 86.6%. There was no significant difference between the three groups. (p > 0.05).

Conclusion: The study showed that the success of indirect pulp treatment is independent of the type of liner used for pulp capping. Moreover, the study also shows that Er,Cr;YSGG laser can be effectively used for indirect pulp capping procedures.
