ZOP pulpectomy

Details and patient eligibility

About

The clinical trial aims to evaluate the clinical and radiographic success of Zinc oxide- propolis versus Zinc oxide -Eugenol as obturating material in pulpectomy of non-vital primary teeth.

Full description

Pulpectomy is considered the most convenient way to treat the non-vital primary teeth as it preserves the affected tooth to maintain the length and integrity of the dental arch until exfoliation4. Zinc oxide-eugenol cement (ZOE) has been used as a root canal filling material for primary teeth and has long been the material of choice of pediatric dentists worldwide, although it fails to meet the ideal requirements of root canal filling material for primary teeth due to limited antimicrobial action, and a slower rate of resorption than the roots of the primary teeth. Concerns about these drawbacks of ZOE directed to search for alternative obturating materials for primary teeth.

Propolis, a natural resinous substance, is collected by honey bees with potent antimicrobial and anti-inflammatory properties. The main chemical constituents present in propolis are flavonoids, phenolics, and other aromatic compounds. Considering these beneficial effects of propolis, a zinc oxide-propolis mixture is suggested to increase the survival rate and improve the treatment prognosis of non-vital primary teeth.

38 participants in 2 patient groups

zinc-oxide propolis

Experimental group

Description:

Propolis is a natural resinous mixture produced by honeybees from substances collected from parts of plants, buds, and exudates. The essential principle compounds responsible for biological activities are polyphenols, aromatic acids, and diterpenic acids. Numerous biological properties of propolis have been reported including cytotoxic, antiherpes, free radical scavenging, antimicrobial, and anti-HIV activities The antibacterial effect of propolis is bactericidal by inhibiting their mobility. Propolis kills the fungi and also inhibits the growth of the viruses.

Treatment:

Drug: Zinc oxide Propolis

zinc-oxide eugenol

Active Comparator group

Description:

Zinc oxide-eugenol cement (ZOE) has been used as a root canal filling material for primary teeth and has long been the material of choice of pediatric dentists worldwide, although it fails to meet the ideal requirements of root canal filling material for primary teeth due to limited antimicrobial action, and a slower rate of resorption than the roots of the primary teeth. Studies report that the success rate of ZOE ranges from 65% to 86% so it's materials of choice if primary teeth are not nearing exfoliation.

Treatment:

Drug: Zinc Oxide-Eugenol Cement
