Clinical and radiographic evaluation of four different zinc-oxide integrated root canal obturating materials used in primary teeth

Abstract

AimTo compare and evaluate the clinical and radiographic success of four different zinc-oxide integrated root canal obturating materials. Materials and method120 grossly decayed primary molars of children, aged 4 to 9 years were selected with signs or symptoms of irreversibly inflamed pulp tissue and randomly assigned to one of the four groups: zinc oxide eugenol, zinc oxide powder with 10% sodium fluoride, zinc oxide powder with Aloe vera, and Endoflas. Single sitting pulpectomy was carried out in all teeth and subsequently restored with a preformed crown in next sitting. Teeth were assessed clinically and radiographically for 3, 6, 9 and 12 months interval. Results90 out of 120 treated molars completed 12-month evaluations. Overall clinical and radiographic success rates were highest for endoflas, followed by zinc oxide-sodium fluoride, zinc oxide-aloe vera and least for zinc oxide eugenol. However, no significant differences between success rates were observed amongst the four study groups (P>0.05). ConclusionsThese results suggest that the sodium fluoride and aloe vera may be considered as suitable alternative root canal obturating materials for primary teeth with low cost to achieve acceptable therapeutic results.
