Success of Direct Pulp Capping and Partial Pulpotomy of Primary Teeth using MTA
2015
The purpose of this study was to compare the clinical and radiographic success rate of direct pulp capping (DPC) and partial pulpotomy (PP) treatment using MTA as pulp capping agent in treatment of primary teeth with pulp exposure after direct complete excavation. Methods: In the research were included 88 primary teeth with deep carious lesions without signs and symptoms of irreversible pulpitis and where pulp exposure occur. All teeth were treated under local anaesthesia and direct complete excavation DPC was conducted when the pulp is exposed up to 1 mm. PP is a procedure in which the inflamed tissue is removed to a depth of 1 mm or deeper. The pulp wound was dressed with grey MTA, GIC. Forty-nine teeth were treated with direct pulp capping and MTA; 53 teeth were treated with partial pulpotomy and MTA. The patients were scheduled for follow-up in 6 and 12 months. Results: The difference in the level of success was not statistically significant (p>0.05) for the groups of teeth t...
MM-MTA for Direct Pulp Capping: A Histologic Comparison with ProRoot MTA in Rat Molars
Aim: To compare the histomorphological response of rat dental pulps capped with MM-MTA and ProRoot MTA at 1, 2 and 4 weeks postoperatively. Materials and methods: Direct pulp capping with MM-MTA and ProRoot MTA, overlaid with light-cured composite resin, was rats. Animals were killed at 1, 2 and 4 weeks postoperatively. Biopsy samples were stained and viewed by light microscopy to determine dentin bridge formation. Data were statistically Results: Absence of dentin bridge formation at 1 week, partial dentin bridge formation at 2 weeks and complete dentin bridge formation at 4 weeks are observed with MM-MTA and ProRoot between both materials at 4 weeks. Conclusion: Both materials produced similar responses in the pulp when used for pulp capping in intact, caries-free molars of rats. Keywords: Direct pulp capping, MM-MTA, ProRoot MTA, Rats molars.
Success of pulpotomy with MTA in primary and permanent teeth
International Journal of Health Sciences (IJHS), 2022
MTA has long been used as a Pulpotomy agent to preserve the pulp vitality, but there is a need to have an evidence-based approach when selecting the most appropriate pulpotomy agent which will be suitable for both dentitions, as the pulp of primary and permanent teeth have many histological and morphological differences. This systematic review aimed to evaluate the success of pulpotomy with MTA in primary and permanent teeth. A computerized literature search was performed through five databases: PubMed, Google Scholar, Microsoft Academics, EBSCO, and Science.gov to identify articles up to December 2020. Randomized controlled trial studies were selected in accordance with the inclusion and exclusion criteria. Out of the 5070 publications initially identified, only 18 studies that fulfilled the inclusion criteria were included in the review. Out of those 18 studies, 9 were studies performed on primary teeth, and the other 9 were performed on permanent teeth. After thorough review and evaluation, it was found that overall treatment success in primary teeth was 88.89-100% and it was 85-100% in permanent teeth. Overall clinical and radiographic success rates after follow-up showed that MTA pulpotomy showed slightly better results in primary teeth as compared to permanent teeth.

Keeping the pulp's vitality must be the dentist's first priority. The purpose of this study is to compare two types of dental materials frequently used in the dental office for non exposed pulp healing (indirect capping): calcium hydroxide and MTA. We compared radiological and clinical findings of the dentine bridge formed after six months of indirect capping. Material and Method: 13 patients were treated in the Department of Caryology and Restorative Odontology of the Dental Faculty, University of Medicine and Pharmacy "Gr. T. Popa" Iasi for the conservative treatment of multiple decays. They had pulp dressing by indirect pulp capping technique.Results: MTA dressing (indirect pulp capping technique) is associated with 55% of the success meanwhile the use of calcium hydroxide is associated with 60% succes rate. Conclusions: Choosing indirect pulp capping techique was based on a careful pulp diagnosis, which was supported by the history of pain and clinical and radiographic findings. This study showed the efficacy of the mineral trioxide aggregate (MTA) and calcium hydroxide for maintaining the pulp vitality, compying with a good technique and with good cooperation of the patient.
Success Rate of MTA Pulpotomy on Vital Pulp of Primary Molars: A 3-Year Observational Study
International Journal of Clinical Pediatric Dentistry
Introduction: Vital pulp therapy is a major contributor in the preservation of primary dentition after caries affliction. Introduction of mineral trioxide aggregate (MTA) has revolutionized such treatment. Aim: The aim of our study was to evaluate and correlate the effects of MTA clinically and radiographically on pulpotomized primary molars till their exfoliation or extraction followed by histological evaluation. Study design: This is an observational study. Materials and methods: A total of 25 teeth were selected from 5-to 8-year-old children requiring pulp therapy on the basis of inclusion and exclusion criterion. The teeth were treated by conventional pulpotomy technique under aseptic conditions using MTA and were immediately restored with stainless steel crown. The teeth were assessed postoperatively till 36 months. The exfoliated or extracted teeth were examined histologically. Results: The pulpotomized teeth were vital with no adverse clinical findings during the observation period. After 3 months, one tooth showed internal resorption, but the same was not observed after 12 months. Pulp canal obliteration was seen in three cases. At the end of the study, five teeth were exfoliated and one tooth was extracted for maintaining arch symmetry. The histological examination of extracted tooth revealed the presence of healthy pulp and the area of true calcification. Remaining exfoliated teeth presented dentin bridge formation. Statistics: Frequencies and percentages were used for descriptive statistics. Fisher's exact tests were used to see the difference between clinical and radiological findings. The probability value was fixed at 5% level of significance. Conclusion: The response of pulp in primary teeth to MTA was favorable in all cases from clinical and radiographic perspective, and histological evaluation confirmed the observation.

Objectives Studies on indirect pulp treatment (IPT) show varying success rates of 73 to 97 %. The necessity of reopening the cavity and the question of the optimal capping material is still under debate. The aim of this prospective in vivo study was to compare the clinical and microbiological outcomes of mineral trioxide aggregate (MTA), medical Portland cement, and calcium hydroxide on the dentin-pulp complex of permanent and primary teeth treated with two-step IPT. Materials and methods In 86 regular patients (51 % men; 49 % women; age 17.2 years ±13.8), one deep carious lesion each was treated with incomplete caries removal, randomly selected capping with either calcium hydroxide (n =31), medical Portland cement (29) or white MTA (26), and re-entry (6.3 months ±1.0). Clinical (color, humidity, and consistency of dentin) and microbiological (Lactobacilli/Mutans Strep. counts) parameters were recorded at the first and second treatment. Results The IPT had a high success rate of 90.3 % regardless of the material used (p =0.72). The arrested lesions showed consistently darker, dry, and therefore, sclerotic dentine (p <0.05) as well as a decrease in bacterial counts at re-entry (Lactobacilli p =0.01/Mutans Strep. p =0.07). Conclusions The findings of this study support the use of the IPT as a treatment for deep carious lesions preferably with nonresorbing materials such as MTA or medical Portland cement. Clinical relevance The findings of this study could promote the improvement of the IPT as a one-step treatment of deep carious lesions when the remaining demineralized dentin would be sealed with durable restorations.
MTA Pulpotomy in Primary Molars: A Prospective Study
Research Journal of …, 2009
This study was designed to evaluate clinical and radiographic success rates of Mineral Trioxide Aggregate (MTA) as a relatively new pulpotomy agent for pulp treatment of primary teeth. This prospective investigation was carried out on a group of children with a mean age of 6.4 years who were referred to Shiraz Dental School for routine care. Pulp amputation was carried out following routine local anesthetic induction on selected primary molars and then MTA (Pro root, USA) was placed over the already formed clot at the canal orifices. All teeth were restored using Stainless Steel Crowns and a recall program was set for 6, 12 and 24 months. Clinical and radiographic evaluations were attempted in all recall visits. Overall 55 primary molar teeth were treated by this new technique 4 of which failed for any follow-up evaluations. Apparently, all of the remaining 51 treated teeth were found to be sound and without any sign or symptoms both by clinical and radiographic means (100% success at 12 and 24 months), postoperatively. Based on the findings of this study it seems that MTA could be used as an alternative to the current Formocresol medication with high clinical and radiographic success in pulpotomy of primary teeth.
