Pulpotomy of primary teeth is a common and daily treatment in pediatric dentistry, and by performing this treatment properly and accurately, tooth pain, infection, and extraction can be prevented. Considering the advantages and disadvantages of various pulpotomy treatment methods, it is necessary to evaluate the success rate of these methods (pulpotomy), in an educational environment.

The intended study is a descriptive study. The files in the pediatric department were reviewed by a dental student. Patients, age range three to seven years old were selected from both genders, boys and girls. Through phone calls, patients were asked to present for a follow-up visit. After obtaining consent, and according to the inclusion and exclusion criteria of the study, The examination was performed using a mirror and explorer and the dental unit’s light. Periapical radiography (parallel technique) was used for radiographic evaluation. To reduce the error of interpretation, each radiograph was evaluated by two people (student and supervisor) independently. The results were statistically analyzed by SPSS20 and descriptive chi-square test.

35 participated in this study which 90 of their  primary molar were treated by  formocresol  in the last 24 months.43/7% of patients were boy and 56/3% were girl.70/3 % of teeth were treated by stainless steel crown,27/8 % by  amalgam and 1 %by composite after pulpotomy procedure. In total,23 cases f all examined teeth had pathological clinical signs, and 66 cased had pathological radiographic signs.

Finally  ,the clinical   and radiographic success rate of pulpotomy was estimated   respectively 76/9 % and 44%.

Vital pulpotomy is performed in primary teeth to preserve the tooth until normal exfoliation. Different materials, such as formocresol, zinc oxide-eugenol, MTA, and Biodentine, are used in this procedure. This study aimed to compare the clinical and radiographic success of pulpotomy treatment in primary molars using formocresol or Biodentine.

In this clinical study, pulpotomy procedures were performed on 66 mandibular primary second molars teeth in 4–7-year-old children, referring tothe Department of Pedodontics, Khorasghan Faculty of Dentistry, Isfahan Azad University, with indications for pulpotomy treatment. In each patient, one tooth was randomly assigned to the formocresol pulpotomy group, and one tooth was assigned to the Biodentine group. The teeth underwent pulpotomy treatments with either formocresol or Biodentine and restored with a stainless steel crown. The clinical and radiographic outcomes were recorded at 6 and 12 months. Data were analyzed with Fisher’s exact test using SPSS 22 (α = 0.05).

Both groups demonstrated 100% clinical success rate at 6-and 12-month follow-ups. However, at 6 months, the radiographic success of formocresol was 84.8% compared to 93.9% in the Biodentine group (p value = 0.21). The radiographic success rates of formocresol and Biodentine were 81.8% and 93.9%, respectively at 12 months (p value = 0.13).

The teeth treated with Biodentine exhibited higher clinical and radiographic success rates as compared to formocresol at 6-and 12-month follow-up, with no statistically significant difference between the two groups. It seems Biodentine can be a proper alternative to formocresol in primary molar pulpotomy procedures.

Formocresol has been used for the pulpotomy procedures of primary molar teeth in the past century; however, new alternatives have been introduced because of the potential carcinogenesis of formocresol. Some natural materials from the field oftraditional medicine, such as propolis, have also been introduced as medicaments for vital pulp therapy procedures. This study compared the clinical and radiographic success of pulpotomy treatment in primary molars, using formocresol or propolis.

In this clinical study, pulpotomy procedures were performed on 60 mandibular second primary molar teeth in 4-7-year-old children, referring to the Department of Pedodontics, Khorasghan Faculty of Dentistry, Isfahan Azad University, with indications for pulpotomy treatment. In each patient, one tooth was randomly assigned to the formocresol pulpotomy group, and one tooth was assigned to the propolis group. The teeth underwent pulpotomy treatments with either formocresol or propolis after achieving anesthesia and removing caries, followed by restoration with a stainless steel crown. The clinical and radiographic outcomes were recorded at 6 and 12 months. Data were analyzed with Fisher’s exact test using SPSS 22 (α = 0.05).

The formocresol group demonstrated 100% clinical success rate at 6-and 12-month postoperative intervals. The clinical success rates of propolis were 96.7% and 100%, respectively at 6-and 12-month intervals, respectively. The 6-month radiographic success in the formocresol group was 83.8% compared to 90% in the propolis group (p value = 0.35). Radiographic success rates of formocresol and propolis were 80% and 76.7%, respectively, at 12 months (p value = 0.75).

The results of this study revealed no significant differences in the success rates of primary molar pulpotomy procedures between propolis and formocresol. Propolis can be used for pulpotomy procedures as a substitute for formocresol.

The structural distinction of primary teeth compared to the permanent teeth leads to a faster penetration of the caries into the pulp, which makes effective treatment necessary. The aim of this study was to determine the success rate of pulpotomy in primary molar teeth and its effective factors using formocresol by students and residents at the department of pediatric dentistry of Hamedan dental school. In this cross-sectional study, 113 children who previously had pulpotomy by formecresol in their primary molars (30 children by residents and 83 children by the students) were randomly evaluated based on referral time (at least 12 months after treatment) in terms of clinical and radiographic success rates. Data were analyzed by SPSS20 software using Chi-square and descriptive statistics. The success of the pulpotomy of primary molar teeth was 81.7%. The success rates of the general students and residents were 79.3% and 87.3%, respectively. The percentage of successful pulpotomy was significantly higher in general students at Stainless Steel Crown (S.S.C), second molar in maxilla (P<0.05), but did not have a significant relationship with age and sex (P>0.05). The percentage of pulpotomy success performed by residents did not have a significant correlation with gender, age, type of repair, type of teeth and jaws (P>0.05). In general, the percentage of success in S.S.C, the second molar and maxillary jaw was higher. Also, the success rate of pulpotomy by residents was significantly higher than that of general- students (P<0.05). The highest rates of pulpotomy failure were related to internal analysis. Formocresol pulpotomy using S.S.C in the maxillary second molar teeth had higher success rate

Pulpectomy is one of the most common treatments for preserving infected primary teeth. Intracanal medicaments have been used to decrease the amount of microorganism. The purpose of present study was to evaluate and compare the antimicrobial effect of some medicaments (formocresol, CMCP and 0.2% chlorhexidine) against some common bacteria isolated from infected primary teeth. Subjects and In this experimental study fifty primary canine teeth were prepared and were randomly divided into 5 groups (n = 10). After sterilization, suspension of bacteria (Streptococcus mutans, Bacillus subtilis, Enterococcus faecalis and Pseudomonas aeruginosa) were inoculated into each canal. Cotton soaked in normal saline as a positive control; and cotton soaked in Formocresol; CMCP and 0.2% chlorhexidine were placed in canal groups(2 to 4). The antibacterial effect of each medicament was evaluated by determining the percentage reduction in colony counts (RCC %) and CFU (colony-forming units) on day 3 after exposure. Kruskal-Wallis test, Dunn's test and SPSS 22 were used to analyze the data. All experimental groups showed a significant decrease in bacterial counts in compassion with control group (P < 0.05). 0.2% chlorhexidine showed significantly lower efficacy compared to formocresol and CMCP group (P < 0.05). According to the present study formocresol and CMCP have good antimicrobial effect.

The aim of this study was to evaluate the clinical and radiographic outcomes of Propolis in pulpotomized primary molars in comparison with Formocresol. In this clinical trial, 26 lower second primary molars of thirteen children were treated by conventional pulpotomy technique. The teeth were randomly assigned to Propolis (experimental) and Formocresol (control) groups in each patient (split mouth).Following removal of the coronal pulp and haemostasis, the pulp stumps were covered with Propolis in the experimental group and then resin-modified glass ionomer cement was applied over the gel. In the control group, Formocresol (FC) was placed with a cotton pellet over the pulp stumps and then reinforced zinc oxide eugenol cement was applied in pulp chamber. Finally, the teeth of both groups were restored with stainless steel crowns the data were analyzed using Mc Nemar test (α=0.05). All patients developed failure clinically within two months of treatment. The radiographic evaluation revealed furcation involvement and extensive radicular radiolucency in molars treated with Propolis. The present study showed the failure of Propolis in pulpotomized primary molars; therefore, it could not be used as a safe medicament for pulpotomy in human primary molars.

Pulpotomy is one of the routine methods for pulp therapy of primary teeth. At present it is a fact that ideal agent for this has not been discovered. The aim of this study was to compare the clinical and radiographic success rates of electrosurgical pulpotomy versus formocresol pulpotomy in human primary molar teeth. In this clinical trial study, pulpotomy was performed on 68 primary molars in children aged from 5 to 10 years. The teeth were treated using either a conventional formocresol (35 teeth), or electrosurgical technique (33 teeth). Following the pulpotomy procedure, the teeth were evaluated regarding clinical and radiographic success for 3, 6 and 9 months periods. The teeth were evaluated clinically and radiographically for the presence of pain, abscess, fistula, mobility, internal and external resorption and radiolucency. Finally clinical and radiographic data were collected and analyzed with Fisher exact test using P<0.05 as the limit of significance. After 9 months follow up, the clinical and radiographic success rates for the electrosurgery group were 96% and 84% respectively and for formocresol group, 100% and 96.8% respectively. There were no statistically significant differences between the success rates for the two groups (P>0/05). Although electrosurgical pulpotomy is a nonpharmacological and easy to use technique, further investigations with longer evaluation periods are suggested.

Statement of Problem: Pulpotomoy is considered as one of the most common treatments among primary teeth. Therefore, search for an appropriate and safe material seems necessary. Studies have proved ferosulfate as a therapeutic material in pulpotomy. The goal of the present study was to compare clinical and radiographic changes of pulpotomy using ferosulfate and formocresol in primary molars among 3-8 year old children. In this clinical trial study, fifteen 3-8 years old children, referred to the pedodontics department, faculty of Dentistry, Tehran University of Medical Sciences were selected. All subjects did not show any systemic disease, with at least two clinically and radiographically accepted posterior teeth for pulpotomy technique. Totally, forty- three teeth were studied. For each patient both materials were used. Following treatment, patients were investigated, clinically and radiographically in 3, 6, 9 and 12 month follow-ups. During follow-up periods, teeth with failures were not excluded and investigated. For data analysis, Chi-square and Fisher’s-exact tests were used and treatment success was evaluated, based on clinical as well as radiographic findings. In all follow-up periods (3, 6, 9 and 12 months after treatment), pulpotomies with formocresol showed more success rate (73.7%) comparing to those with ferosulfate (70.8%), although the difference was not statistically significant (P>0.05). Statistical tests revealed no significant difference between two different treatment techniques regarding pain, external and internal resorption, calcified metamorphosis, abcess, apical root resorption, apical and interradicular radiolucency. Although ferosulfate, due to its less toxicity, may be considered as a proper substitute for formocresol in primary molars pulpotomies, more studies with longer-term follow up and larger sample size are required to determine its long-term effects.

Pulpotomy is among the most common methods for the treatment of the primary tooth pulps and the drug of choice in that method is formocresol. Our main objective of doing pulpotomy with formocresol is to maintain the tooth in an asymptomatic condition until normal resorption till exfoliation occurs. The purpose of this study was to examine the success rate of a two-visit pulpotomy with formocresol in vital primary molar teeth, after at least two years. The population under study consisted of 36 children, 5-10 years-old, referring to the special clinic of Shiraz School of Dentistry, all of whom were treated by the project executor.

72 pulpotomized teeth in the mouths of 36 children in the 5-10 years age group (40 boys and 32 girls) who were treated from April 1992 up to June 2001 were examined and they were evaluated clinically and radiographically from March up to June 2003.

Among 72 teeth under the study, some were excluded from the study during the process due to various reasons, so that in the clinical study, 70 teeth and in the radiographic study, 55 teeth were studied. As a whole, considering the mean time period of 30 months after treatment, the clinical success rate of 94.3% and the radiographic success rate of 85.5% were obtained (Table and Graph no.1,2).

As in different studies in which the success rate of pulpotomy treatment with formocresol is reported to be between 70 to 90%, the success rate in the current study was in the same range, though we have not been strict in choosing the teeth for treatment, an issue which probably has had a significant role in reducing the success rate of treatment. In numerous other studies, the highest rate of failure is related to internal root resorption, which includes about 85.5% of the total unsuccessful treatment in this study and 12.5% of failure rate belonging to external pathologic root resorption.
