Clinical and radiographic evaluation of polyantibiotic paste and metapex for pulp therapy in primary molars

Aim: To compare the clinical and radiographic success of polyantibiotic paste and Metapex for pulp therapy of primary molars. Methods: A prospective single-blind randomized design comprising a total of thirty pulpally involved primary molars from 27 healthy children aged 3?8 years and were treated with Group A (containing Neosporine, Bacitrecin Polymyxin B; Ornidazole, Nodifloxacin) and Group B. For polyantibiotic paste LSTR (‘Lesion sterilization and tissue repair therapy) was used and for Metapex conventional pulpectomy method was used. The outcome was compared using a Z-test with a significance level of 0.05. Results: Group A and Group B showed 100% and 96% clinical success respectively after 3 months. Considering the radiographic findings at the end of 3months, no statistically significant difference (P=0.36665) was found between the two groups. Conclusions: It can be concluded that both polyantibiotic paste and Metapex can be used as a medicament for pulp therapy in primary teeth with poor prognosis. However, long term clinical studies should be carried out to evaluate the clinical efficacy of the material used.
