Comparative Study of Some Natural Materials Versus Traditional Medicaments used for Pulp Treatment of Primary Teeth

Purpose: To evaluate clinically, radiographically and histologically the postoperative success of Miswak, Allium sativum and Nigella sativa extracts use in pulpotomy procedures for primary teeth Materials and Method: 92 Primary teeth found in 26 patients were selected according to inclusion criteria. In the first part of the study pulpotomy was accomplished in 20participants having 80 teeth and depending on the type of radicular pulp medicament, the teeth were divided randomly and equally into four groups: Group I (Miswak group),GroupII (Nigella sativa group),GroupIII(Allium sativum group) ,Group IV(formocresol group). Clinical follow up was done after 1,3, and 6 months.Periapical radiographs also were taken at 3and 6months follow up visits only. In the second part of the study 12 primary molars planned for extraction due to orthodontic purpose were treated by pulpotomy procedure and then the teeth were grouped into four groups and then the teeth extracted after 2 months and were observed under light microscope. Results: No statistically significant difference between groups in the overall cumulative clinical or radiographic success at follow up visits. Histopathological examination revealed dentine bridge formation in primary molars treated with Miswak, Nigella sativa treated primary molars showed absense of odontoblastic layer, Allium sativum showedwell organized odontoblastic layer and chronic inflammatorycellular infiltration, whileformocresolspecimens showed sever hyperemia and hyalinization of pulp stroma. Conclusion: Miswak, and Allium sativum can be considered as good natural alternatives to formocresol in primary molars pulpotomy,however Nigella sativa cannot be a suitable substitute to formocresol.
