RESUMO
BACKGROUND: Given the side effects of formocresol as a common substance in dental pulpotomy, its substitution with a safe substance seems mandatory. AIM: To compare the clinical and radiographic success of Allium sativum oil and formocresol in the pulpotomy of the primary molars. MATERIALS AND METHODS: A randomized, split-mouth, double-blind, controlled clinical trial was conducted on children with at least two asymptomatic primary molars requiring pulpotomy. A total of 90 teeth were examined in this study. They were randomly divided into two groups: the A. sativum (ALL) group (n = 45) and the formocresol (FC) group (n = 45). After pulpotomy, A. sativum oil was applied to the radicular pulp in the ALL groups and formocresol in the FC group. The pulp chamber was then filled with reinforced Zinc oxide Eugenol and finally restored by a stainless steel crown. Three and six months after the intervention, the teeth were evaluated by a colleague based on a modified criteria system. The results were analyzed using Wilcoxon's test. RESULTS: The clinical success rate was 100% in both groups after 3 and 6 months. The radiographic success rate in the ALL group and the FC group after 3 and 6 months was 82.2% and 80% and 88.9% and 84.4%, respectively. The difference between the two groups was not statistically significant (P = 0.46). CONCLUSION: According to the results of this study, A. sativum oil can be used in the pulpotomy of the primary molars.
RESUMO
OBJECTIVES: This study aimed to assess the reaction of dental pulp of pulpotomized teeth with/without applying a capping agent. This study was performed as randomized clinical trial. MATERIALS AND METHODS: This split-mouth clinical trial was conducted on eight pairs of primary canine teeth scheduled for extraction as part of orthodontic treatment. The teeth were randomly assigned to the intervention and control groups. In the intervention group, canine teeth were restored with amalgam after pulpotomy with formocresol. In the control group, zinc oxide eugenol paste was applied as the capping agent after pulpotomy with formocresol, and the teeth were then restored with amalgam. After 1 month, the teeth were extracted in both groups and stained with hematoxylin and eosin for histological analysis. Pulp reaction was assessed in terms of pathological parameters. Data were analyzed using the Mann-Whitney U-test and Fisher's exact test. The statistical analysis software was SPSS 16. RESULTS: No significant difference was found between the two groups in terms of inflammation, vitality, internal resorption, bleeding, presence of osteoclasts and dentinoclasts, and internal regeneration. Dentinal bridge did not form in any group. CONCLUSION: According to the results of this study, formocresol pulpotomy of primary teeth can be completed without the application of a capping agent.
