Comparison of Clinical and Radiographic Success Rates of Pulpotomy in Primary Molars using Ferric Sulfate and Bioactive Tricalcium Silicate Cement: An in vivo Study

Apoptotic effects of biodentine, calcium-enriched mixture (CEM) cement, ferric sulfate, and mineral trioxide aggregate (MTA) on human mesenchymal stem cells isolated from the human pulp of exfoliated deciduous teeth

BACKGROUND

Preservation of primary teeth in children is highly important. Pulpotomy is a commonly performed treatment procedure for primary teeth with extensive caries. Thus, biocompatibility of pulpotomy agents is highly important. Biodentine, calcium enriched mixture (CEM) cement, ferric sulfate, and mineral trioxide aggregate (MTA) Angelus are commonly used for this purpose. Thus, this study aimed to assess the apoptotic effects of Biodentine, CEM cement, ferric sulfate, and MTA on stem cells isolated from the human pulp of exfoliated deciduous teeth.

METHODS

In this in-vitro, experimental study, stem cells isolated from the human pulp of exfoliated deciduous teeth were exposed to three different concentrations of Biodentine, CEM cement, ferric sulfate, and MTA for different time periods. The cytotoxicity of the materials was evaluated by flow cytometry using the annexin propidium iodide (PI) kit. Data were analyzed by ANOVA and Tukey's test at P<0.05 level of significance.

RESULTS

All four tested materials induced significantly greater apoptosis compared with the control group. The difference in cell apoptosis caused by the first concentration of ferric sulfate and MTA was not significant at 24 hours. In other comparisons, the cytotoxicity of ferric sulfate was significantly lower than that of other materials. Biodentine showed higher cytotoxicity than MTA at first; but this difference faded over time. The cytotoxicity of CEM cement was comparable to that of MTA. The highest cell viability was noted at 24 hours in presence of the minimum concentration of ferric sulfate. The lowest cell viability was noted at 72 hours in presence of the maximum concentration of CEM cement.

CONCLUSIONS

In comparison with other materials, ferric sulfate showed minimum cytotoxicity; the cytotoxicity of the three cements was comparable. It appears that the concentration of ferric sulfate and the composition of cements are responsible for different levels of cytotoxicity.

Efficacy of orthoMTA, retroMTA and ferric sulphate as pulpotomy agents in primary molars: a randomized clinical trial

Purpose

The purpose of this study is to evaluate the clinical and radiographic success rates of RetroMTA, OrthoMTA, and ferric sulfate as pulpotomy agents in primary molars.

Materials and methods

Ninety-six primary second molars from 32 children aged 5 to 9 years were enrolled in this study. The teeth were randomly divided into three groups based on the pulpotomy agent used: O-MTA, R-MTA, and FS. Clinical and radiographic follow-up examinations were conducted at 3, 6, 9, and 18 months postoperatively.

Results

At the end of the study period, 84 teeth were evaluated. The clinical success rates were 75% for FS, 96.4% for O-MTA, and 92.8% for R-MTA groups. In the radiographic analysis, the success rates at the 18-month follow-up period were 50% for FS, 85.8% for O-MTA, and 82.2% for R-MTA groups. According to the Chi-square test and Kaplan-Meier survival analysis, there was a statistically significant difference among the success rates and survival probabilities of the groups (p<0.05).

Conclusion

OrthoMTA and RetroMTA demonstrated better treatment outcomes for pulpotomy of primary second molars than ferric sulfate at the 18-month follow-up period.

COMPARING THE CLINICAL AND RADIOGRAPHIC OUTCOMES OF PULPOTOMIES IN PRIMARY MOLARS USING BIOACTIVE ENDODONTIC MATERIALS AND FERRIC SULFATE - A SYSTEMATIC REVIEW AND META-ANALYSIS OF RANDOMIZED CLINICAL TRIALS

OBJECTIVE

To compare the clinical and radiographic outcomes of pulpotomies in primary molars using bioactive endodontic materials and ferric sulfate.

DESIGN

The search was conducted in PubMed, Ebscohost, ProQuest, and Scopus databases till June 2021. Children undergoing pulpotomy therapy in primary molars treated with ferric sulfate (FS) and bioactive endodontic materials were evaluated for clinical and radiographic success. Meta-analysis was performed on a random-effects model to assess the success at 6,12,18, and 24 months. The quality of studies was evaluated using the Cochrane risk of bias tool for randomized trials RESULTS: No significant difference was observed between Mineral trioxide aggregate (MTA) and FS at 24 months for both clinical [RR0.98 (95%CI 0.15,6.34), I² = 0%] and radiographic [RR0.74 (95%CI: 0.23,2.43), I² = 0%] success. At 6 months [RR1.36 (95%CI: 0.10,19.34), I² = 33%], no difference was observed in the clinical [RR1.00 (95%CI: 0.95,1.05), I² = 0%] and radiographic success [RR0.99 (95%CI: 0.88,1.11), I² = 51%] between Biodentine (BD), FS and radiographic success of calcium enriched cement and FS [RR0.25 (95%CI: 0.03, 2.22), I² = 0%].

CONCLUSION

Amongst bioactive materials, MTA and FS demonstrated equal success rates in both clinical and radiographic outcomes with follow-up periods of up to 24 months. Future, high-quality trials are required to verify the result of the current review.

To Evaluate and Compare the Clinical and Radiographic Outcomes of Formocresol, Mineral Trioxide Aggregate, Electrocautery, and Bioactive Glass when used for Pulpotomy in Human Primary Teeth

AIMS

The aim of the present study is to evaluate and compare the clinical and radiographic outcomes of formocresol (FC), mineral trioxide aggregate (MTA), electrocautery, and bioactive glass (BAG) when used for pulpotomy in human primary teeth.

SETTINGS AND DESIGN

The present study comprised of total four Groups A, B, C, and D; the selected children for the procedure were randomly divided into four groups according to the type of agent used as Group A, Group B, Group C, and Group D, respectively, having 20 teeth.

METHODOLOGY

In this study, pulpotomies were performed on the respective teeth. The teeth were treated using either FC, MTA, electrocautery, and BAG. Following the pulpotomy procedure, the teeth were evaluated for the clinical and radiographic success for 3, 6, and 12 months. The teeth were evaluated for the presence of pain, swelling, internal and external resorption, and radiolucency.

STATISTICAL ANALYSIS USED

Fisher's exact test and Yates corrected Chi-square test is used.

RESULTS

After 12 months of follow-up, the clinical and radiographic success rates were high. Comparing the frequency (%) of overall clinical success rate of four groups at 12 months, the Chi-square test revealed significantly different and higher overall clinical success rate in MTA as compared to other groups, especially FC and EC at 12 months. Comparing the frequency (%) of overall radiographic success rate of four groups at 12 months, the Chi-square test revealed significantly different and higher overall radiographic success rate in MTA as compared to other groups, especially FC and EC at 12 months.

CONCLUSIONS

In this study, the success rates of MTA, BAG, and FC are matching their physical and chemical properties which have been detailed and explained earlier.

Evaluation of the bond strengths of restorative materials to primary tooth dentin treated with different pulpotomy techniques

The aim of this study was to investigate the changes of different pulpotomy techniques on the primary tooth dentin and to evaluate the effects of these pulpotomy methods on the shear bond strength of restorative materials to primary tooth dentin. Two hundred and forty dentin specimens were distributed randomly to the study groups as; control, ferric sulphate, Biodentine® , Nd:YAG laser, photobiomodulation, and atmospheric pressure cold plasma (APCP). After the application of pulpotomy methods, samples were again randomly divided to two restorative materials (glass hybrid and composite resin) (n = 20) and shear bond strength (SBS) test was performed. Then, 12 new dentin specimens were prepared for all groups for surface analysis. Surface examination (n = 12) and fracture analyses (n = 240) were carried out with scanning electron microscope (SEM). Statistical significance range was accepted as α <.05 for all data. A statistically significant difference was obtained among all study groups for glass hybrid material as well as composite material (p <.05). While the highest mean SBS value was obtained with Nd:YAG laser (7.58 ± 0.60 MPa), the lowest value was observed with Biodentine® (6.70 ± 0.91 MPa; p = .001) for glass hybrid material. For composite material, the highest mean SBS value was calculated for Nd:YAG laser (13.79 ± 1.24 MPa), while the lowest value was obtained with ferric sulphate (10.17 ± 1.45 MPa; p = .001). Fracture modes were mainly adhesive and mixed type according to SEM analysis. Moreover, morphological changes were observed with SEM on the dentin surfaces of ferric sulphate, Biodentine® and Nd:YAG laser. Within the limitations of this study, Nd:YAG laser increased the shear bond strength values in groups of composite resin. RESEARCH HIGHLIGHTS: In this article, we report the results of the shear bonding strength test of two restorative materials (glass-hybrid vs. composite resin) to primary tooth dentin following the application of five different pulpotomy techniques (ferric sulfate, Biodentine® , Nd:YAG laser, photobiomodulation, and atmospheric pressure cold plasma) were reported. This article will contribute to the literature that there are considerably limited researches concerning the bond strength of glass hybrid to primary dentin and also atmospheric pressure cold plasma in pulpotomies. The SEM examination was performed in two stages in this study; the morphological changes in both treated dentin surfaces and the surfaces of the samples subjected to the shear bond strength test.

Clinical and Radiographic Evaluation of Aloe vera vs Formocresol as a Pulpotomy Medicament in Primary Molars: A Double Blinded Randomized Controlled Trial

Aim

The aim of this clinical trial is to compare the clinical and radiographic success of Aloe vera and formocresol (FC) as a pulpotomy medicament in primary molars.

Materials and methods

A total of 72 asymptomatic or symptomatic vital primary molars were selected and were assigned to two groups: group II: Buckley's FC, group II: Aloe vera gel. The clinical and radiographic success were evaluated using Zurn and Seale criteria. The data were statistically analyzed using the Chi-square test.

Results

At three and 6 months follow-up, the clinical success rate of Aloe vera and FC was equally effective. Aloe vera showed a higher radiographic success rate compared to FC (p > 0.05). At 6 months follow-up, FC showed a higher radiographic success rate compared to Aloe vera (p > 0.05).

Conclusion

The clinical and radiographic success of both groups were equally effective at the end of 6 months follow-up. Aloe vera can be considered as an alternative pulpotomy medicament to FC. But, further long-term follow-up studies and histological studies are required.

Clinical and radiographic evaluation of biodentine versus calcium hydroxide in primary teeth pulpotomies: a retrospective study

BACKGROUND

Pulpotomy is the surgical removal of the entire coronal pulp with preservation of the radicular pulp vitality. The purpose of this retrospective study was to evaluate the clinical and radiographic success of pulpotomy of primary molars using two materials, biodentine and calcium hydroxide.

METHODS

Records of 400 primary molars in 360 paediatric participants (mean age: 7.5 ± 1.6 years, ranging from 5 to 9 years) with dental caries who required pulp therapy were included in this study. Biodentine was used on 200 teeth, and calcium hydroxide (CH) was used on another 200 teeth, as a pulpotomy material. Clinical and radiographic evaluation was performed after 9 and 18 months. Statistical analysis was evaluated with the chi-squared test, and the level of significance was set at p < 0.05.

RESULTS

The treatment success with CH was 85.5% after 9 months and 79.5% after 18 months, while the success rate of biodentine was 94% after 9 months and 89.5% after 18 months. The statistical analysis with the Chi-squared test showed that the clinical and radiographic success rate with biodentine was significantly higher than CH (p < 0.05).

CONCLUSIONS

Biodentine exhibited a higher clinical and radiographic success rate compared to CH. However, besides the clinical results, biodentine has some disadvantages, such as higher costs, compared to CH.

Success Rates of Pulpotomies in Primary Molars Using Calcium Silicate-Based Materials: A Randomized Control Trial

Objective

The aim of this study was to evaluate and compare, both clinically and radiographically, the effects of calcium silicate-based materials (i.e., ProRoot MTA [PR-MTA], MTA-Plus [MTA-P], and Biodentine [BD]) and ferric sulfate [FS] in pulpotomy of primary molars.

Materials and Methods

In this randomized clinical trial, 29 healthy 5- to 7-year-old children with at least four carious primary molars with no clinical or radiographic evidence of pulp degeneration were enrolled. The pulpotomy agents were assigned as follows: Group 1: BD; Group 2: MTA-P; Group 3: PR-MTA; and Group 4: FS. Clinical and radiographic evaluations were performed at 6, 12, and 24 months. Data were analyzed using chi-square tests.

Results

Total success rates at 24 months were 82.75%, 86.2%, 93.1%, and 75.86%, respectively. No statistically significant differences in total success rates were observed among the groups at 6-, 12-, and 24-month follow-ups. When the groups were compared according to follow-up times, the success rates in each group did not vary significantly among the 6–12-month, 6–24-month, or 12–24-month periods (p > 0.05).

Conclusion

Although the success rates of BD, MTA-P, MTA-PR, and FS did not differ significantly, calcium silicate-based materials appeared to be more appropriate than FS in clinical practice.
