Abstract
<b>Aim:</b> This in vitro study was carried out to assess the clinical and radiographic success of pulpotomy in primary molars following the use of formocresol, sodium hypochlorite 5% (NaCOl) and Calcium Enriched Mixture (CEM) cement. <b>Materials and methods:</b> This study was conducted on 108 primary molars of 5-8 year old children who referred to the pediatric dentistry, Isfahan faculty of dentistry. The selected teeth were equally distributed and randomly assigned to 3 groups of formocresol, sodium hypochlorite and CEM cement. After taking the initial radiography, standard pulpotomy was carried out by using formocresol, CEM cement and sodium hypochlorite 5%, and the teeth were restored by Stainless Steel Crown (SSC). The clinical and radiographic evaluations were performed at 6 and 12-month follow-ups. Data was analyzed by chi-square and Relative Risk statistical tests. <b>Results:</b> After 6 months, all (100%) of the pulpotomy medicaments were clinically successful. Also, there was no clinically significant difference between the results of primary molar pulpotomy in these 3 groups in the 1-year follow-up (p=0.129). There was not any significant difference between three groups in the first follow-up (p=0.364) and second follow-up (p=0.100). Conclusion: There was no significant difference among the success rates of the pulpotomy medicaments used in primary molars. Moreover, the clinical and radiographic success rates of NaOCl 5% and CEM cement were comparable to those of formocresol.
Highlights
Despite recent developments in preventive dentistry and increasing significance of preserving the teeth, the primary teeth are lost early due to decay or trauma
If inflammation is limited to the coronal pulp and the root pulp tissue is healthy, pulpotomy will be the treatment of choice (3)
In a study conducted by Khorakian et al (13) on 102 primary second molars, the clinical and radiographic success rate of pulpotomy by using Calcium Enriched Mixture (CEM) cement was assessed in [6, 12] and 24-month follow-ups and the findings demonstrated the clinical success rate of 100% and radiographic success rates of 95.9%, 97.9% and 90%, respectively
Summary
Despite recent developments in preventive dentistry and increasing significance of preserving the teeth, the primary teeth are lost early due to decay or trauma. Loss of primary dentition leads to irregularity in permanent dentition and psycho-social consequences (1,2). To prevent these consequences, early intervention is required to cure inflammation and infection of primary teeth pulp. Having removed the coronal inflamed pulp, the remaining root pulp needs to be covered with a pulp medicament which is ideally life-compatible and bactericidal, capable of creating biological seal and inducing hard tissue formation (5). To this end, various medicaments have been introduced. Pulpotomy of primary dentition is defined as a clinical process of removing
