Clinical and Radiographic Success Rates of Pulpotomies in Primary Molars Treated with Formocresol, BiodentineTM, and Endo Repair: A Randomized Clinical Trial

Objective: To compare the clinical and radiographic success rates of formocresol, BiodentineTM, and Endo Repair agents in primary molars after 12 months. Material and Methods: This randomized double-blind clinical trial was conducted on healthy children referred to the Department of Pediatric Dentistry, Kerman, Iran, in 2018. One hundred twenty children (human primary molar teeth) aged 3-9 years were selected and randomly divided into three interventions (with pulpotomy medicament agents), including formocresol, BiodentineTM, and Endo Repair. All pulpotomized teeth were restored using stainless steel crowns and evaluated clinically and radiographically during a 12-month follow-up. Fisher exact test was used to determine the association of categorical variables and the data were analysed with SPSS 25. Results: All the available teeth in formocresol and BiodentineTM groups obtained clinical success, whereas 62.5% of the Endo Repair group was successful in this regard. Radiographic success rates of the formocresol, BiodentineTM, and Endo Repair groups were 94.7%, 70%, and 28.1% after a 12-month follow-up, respectively. Moreover, pulp canal obliteration was observed in 26.3%, 25%, and 12.5% of the formocresol, BiodentineTM, and Endo Repair groups. Conclusion: This study reported a high rate of clinical success using both BiodentineTM and formocresol pulpotomy techniques. However, the radiographic success rate of formocresol was higher than that of BiodentineTM, and Endo Repair was not considered a suitable pulpotomy medicament agent

Comparison of Postoperative Pain Following One-Visit and Two-Visit Vital Pulpectomy in Primary Teeth: A Single-Blind Randomized Clinical Trial

Introduction: The aim of this study was to compare post-operative pain following one-visit pulpectomy and placing stainless steel crown (SSC), with two-visit treatment (performing pulpectomy at the first visit followed by placing SSC at the next visit one week later) in vital pulp of primary molars with carious involvement. Methods and Materials: In this randomized clinical trial, 100 children aged 6-12 years with a carious primary molar tooth in need of pulpectomy were randomly divided into two groups of 50 each. In one-visit group, pulpectomy and placement of SSC were carried out at the same appointment. In two-visit group, pulpectomy of root canals was carried out at the first visit and placement of SSC was performed at the second visit one week after the first appointment. Post-operative pain was recorded using visual analogue scale (VAS) during one week after each treatment visit. Results: No significant difference was found in the mean age and gender distribution between the two groups (P˃0.05 for both comparisons). Findings revealed that in the two-visit (pulpectomy) group during first three days and 4-7 days after the first treatment appointment, pain felt by the children was significantly lower than that felt by the one-visit group at the same time period (P˂0.0001 for both comparisons). Moreover, children in two-visit (pulpectomy) group consumed significantly lower amount of analgesics than those in the one-visit group (P<0.0001). Conclusion: No significant difference was found between pain felt by children during the first three days following one-visit pulpectomy and placement of SSC at the same appointment. Therefore, one-visit treatment of vital primary tooth is recommended.Keywords: Children; One-Visit; Pain; Postoperative; Primary Teeth; Pulpectomy; Two-Visi

Evaluation of the Beliefs of Parents in Iran about How to Care for Children During Dental Visits

Parents play an important role in their children’s dental care and in their behavior during dental visits. Separating children from their parents during dental visits has been a challenging subject of debate for many years. Therefore, this study aims to evaluate parents’ attitudes about being present during their children’s visits to the dentist. The subjects for this cross-sectional study included 340 Iranian parents of five-10-year-old children who had been referred to dental clinics in Kerman, Iran. For this study, the parents of these children completed self-administered questionnaires. Results showed that 218 parents (64.1%) agreed with leaving the practice room during their child’s treatment, while 122 (35.9%) did not agree. The main reason expressed by 41.3% of the parents for leaving the practicing room was that the dentist would be better able to control the child if they were alone. Another reason, cited by 16.5% of the parents, was not wanting to see their child suffering, and 42.2% said they believed that their child would be better treated if they were not present. Most parents who were in agreement with leaving the practice room while their child was receiving dental care felt this would lead to a better treatment outcome
