Aim and objective: To compare the efficacy of triple antibiotic paste (TAP) and double antibiotic paste (DAP) for root canal disinfection during revascularization of immature pulpless teeth.
Materials and methods: A sample of 20 immature teeth in subjects aged 8–13 years was selected for a revascularization procedure. The teeth were randomly distributed in two groups corresponding to the medicament received—TAP group (n = 10) and DAP group (n = 10). Microbial samples were collected using dry paper points at the beginning of treatment and thereafter every 3 weeks till sterile reading was obtained. Microbial samples were then sent to the microbiological lab for identification.
Results: A variety of opportunistic microbes were detected in samples obtained before placement of medicaments with no significant difference between the two medicament groups. The efficacy of TAP to eliminate microbes was lower in comparison to DAP after 3 weeks of placement of medicaments, whereas it was found to be more efficacious in comparison to DAP after 6 weeks and no significant difference (p> 0.05) was observed between the two groups.
Conclusion: Immature permanent teeth with pulp necrosis can achieve complete root development with regenerative endodontic technique. The use of antibiotic pastes including TAP and DAP can help achieve a successful outcome with thorough decontamination of the root canal.
