Pulpectomy helps to preserve a pulpally involved carious primary tooth by abolishing bacteria and their products and also ensures hermetic seal of the root canals thereby allowing the primary teeth to fulfill its function until normal exfoliation can occur without harming the successor or affecting the health of the individual.Till date, numerous materials such as Zinc oxide eugenol (ZOE), calcium hydroxide, calcium hydroxide with iodoform paste, Guedes-Pinto paste ( a drug combination composed of Iodoform, Rifocort® ointment and Camphorated Paramonochlorophenol (CPC),[6] KRI paste, Maisto’s paste, Walkhoff’s paste, etc. have been tested for their efficiency as root canal filling materials, but none of these have shown to possess all the requisite properties of an ideal root canal filling material for primary teeth, especially with regard to the major desirable property of having a rate of resorption matching that of the physiologic root resorption of the primary teeth.Endoflas (Sanlor & Cia. S. en C.S., Cali, Colombia), a resorbable paste produced in South America, contains similar components as Vitapex, with the addition of zinc-oxide and eugenol. This paste is obtained by mixing a powder containing tri-iodmethane, zincoxide, calcium hydroxide, barium sulfate and iodine dibutilorthocresol with a liquid consisting of eugenol and paramonochlorophenol. There are many advantages of using herbs as antimicrobial agent’s minimal side effects, cost-effective, better patient tolerance, renewable in nature, and non-toxic.[11] One such ancient herb is Ocimum sanctum. It contains 0.7% volatile oil consisting of about 71% eugenol and 20% methyl eugenol.

This is a novel study as no study using mixture of Endoflas FS and Ocimum sanctum as an obturating material has been done till date.

Hence, the current study attempts to replace the higher concentration of Eugenol with a milder concentration using Ocimum sanctum which also has antibacterial, anti-inflammatory effects.
