Elective full pulpotomy in mature permanent teeth diagnosed with symptomatic irreversible pulpitis: a two years retrospective study.

AIM: To investigate the outcome of elective full pulpotomy, using calcium silicate-based cements (CSBC), after 2 years, in symptomatic mature permanent teeth with carious lesions, diagnosed as irreversible pulpitis, and analyse the capacity of Wolters et al. (2017) classification to predict the likelihood of treatment failure. METHODS: The treatment records of 56 patients with symptomatic mature teeth with carious lesions, diagnosed as irreversible pulpitis and treated by elective full pulpotomy, using CSBCs as pulp capping materials, were reviewed. Thirteen teeth were excluded. The remaining 43 teeth were evaluated retrospectively at 24 months. Fisher`s exact test with the Lancaster's mid-P adjustment was used to assess different outcomes amongst the diagnostic categories. RESULTS: Four of the cases failed before 24 months and required root canal treatment (RCT). Overall success rate at 2 years was 90.7% (39 of 43). An inverse, but non-significant, correlation was observed between the severity of pulpitis according to the Wolters classification and the treatment success rate (p > 0.05). The type of CSBC used was associated to the success rate (OR = 10.5; 95% C.I. = 0.5 - 207.4; p = 0.027), being 82% with Endosequence and 100% with Biodentine. Postoperative pain associated significantly to lower success rate (66.7%) (Odds ratio = 8.0; 95% C.I. = 0.7 - 95.9; p = 0.047). CONCLUSIONS: Elective full pulpotomy using a CSBC was a successful choice for the treatment of mature permanent teeth with symptoms indicative of irreversible pulpitis. There were no significant differences between the success rate of mild, moderate and severe pulpitis. Postoperative pain could be considered a risk marker for failure of full pulpotomy. The term "irreversible pulpitis" should be re-signified to indicate the need for access to the pulp chamber, rather than an indication for extraction or RCT.

The effect of two different contemporary chelating agents on vital pulp therapy in mature permanent teeth with irreversible pulpitis using bioceramic material: randomized clinical trial.

BACKGROUND: Vital pulp therapy maintained functionality, vitality, and asymptomatic teeth. Compared to normal root canal treatment, pulpotomy was more helpful for irreversible pulpitis in adult permanent teeth. The research was aimed to assess effectiveness of vital pulp therapy using mineral trioxide aggregate with Apple Vinegar and Ethylene diamine tetra acetic acid (17%) for five minutes in adult carious exposed pulp of permanent teeth. METHODS: Forty patients between 18 and 50 years old with a clinical diagnosis of symptomatic irreversible pulpitis but no periapical radiolucency were then divided randomly into two groups based on the irrigation method; ethylene diamine tetraacetic acid or apple vinegar. If pulpal bleeding could not be managed in less than six minutes, the assigned procedure was abandoned. After mineral trioxide aggregate application as a pulpotomy agent, glass ionomer and composite restoration were placed. Using a visual analogue scale, the pre and post-operative pain were recorded after 2,6,24,48, and 72 h. Success was assessed using radiographic and clinical examination data at three, six, and twelve months. RESULTS: The success rate was discovered to be non-statistically significant in both groups after a year follow-up. Apple vinegar had a lower mean value than ethylene diamine tetra acetic acid at the preoperative baseline pain level, which was significant.Postoperatively, the ethylene diamine tetraacetic acid group reported the greatest mean value after two hours while Apple vinegar group reported the lowest mean values after 48 h (P < 0.05). After 72 h, pain level recorded insignificant difference. CONCLUSION: Apple vinegar yielded a marginally successful outcome but substantially improved pain alleviation. TRIAL REGISTRATION: The trial was registered in Clinical trials.gov with this identifier NCT05970536 on 23/7/2023.

Outcome of partial and full pulpotomy in cariously exposed mature molars with symptoms indicative of irreversible pulpitis: A randomized controlled trial.

AIM: The aim of this study was to assess and compare the clinical and radiographic outcome of partial pulpotomy and full pulpotomy using Biodentine in cariously exposed mature molar teeth with symptoms indicative of irreversible pulpitis. METHODOLOGY: This study is an unicentric, double-arm, randomized superiority clinical trial with parallel experimental groups, registered under CTRI (CTRI/2019/12/022559). Fifty mature permanent molar teeth with carious exposures with symptoms indicative of irreversible pulpitis were randomly allocated equally into two groups. Partial pulpotomy (PP) and full pulpotomy (FP) were performed in the first and second group, respectively, following standardized protocols. Exposed pulp tissue was removed up to a depth of 2-3 mm for partial pulpotomy, whereas complete coronal pulp tissue was removed up to the level of root orifices for full pulpotomy. Haemostasis was achieved with placement of 2.5% sodium hypochlorite-moistened cotton pellets placed on amputated pulp tissue for a maximum of 10 min. Biodentine was used as the pulp capping material. Pain scores were evaluated using 11-point Visual Analogue Scale (VAS) preoperatively, at 24 h, 48 h and 7th day after the intervention(s). Clinical and radiographic evaluation was done at 3 months, 6 months and 1 year. The data were statistically analysed using chi-squared test, Mann-Whitney U-test, Friedman's test and Wilcoxon signed-rank test. The significance level was pre-determined at p < .05. Cumulative survival probabilities were assessed at 12 months using Kaplan-Meier analysis. RESULTS: Intra-group analysis of pain scores revealed significant reduction in pain scores preoperatively and at 24 h, 48 h and 7th day in both the groups. However, the difference in the pain score(s) reduction between both the groups was not statistically significant at any time interval (p > .05). At 1-year follow-up, the success rate was 88% (22/25) and 91.6% (22/24) for PP and FP respectively (p > .05). CONCLUSIONS: Partial pulpotomy showed comparable results to full pulpotomy in terms of clinical/radiographic treatment outcome. If the long-term results remain the same, partial pulpotomy can be proposed as an alternative treatment modality for mature teeth with cariously exposed pulp tissue presenting with signs of symptomatic irreversible pulpitis.

Comparative evaluation of complete and partial pulpotomy in mature permanent teeth with symptomatic irreversible pulpitis: A randomized clinical trial.

AIM: The study aimed to compare the outcome of complete pulpotomy (CP) and partial pulpotomy (PP) techniques when utilised for the management of mature permanent teeth with carious pulpal exposure and symptomatic irreversible pulpitis (SIP). METHODOLOGY: The study protocol was registered with ClinicalTrials.gov (NCT04397315). One hundred and six permanent mandibular molars with carious pulpal exposure and clinical diagnosis of SIP with periapical index ≤2, from patients aged between 18 and 40 years were randomly allocated in equal proportion to either CP or PP group. Allocated procedures were performed using standardised protocols. The allocated procedure was abandoned in cases where pulpal bleeding could not be controlled within 6 min using cotton pellets soaked in 3% sodium hypochlorite. MTA was used as a pulpotomy agent and teeth were restored using a base of glass ionomer followed by composite restoration. The pain was recorded by the patient preoperatively before administration of local anaesthesia and postoperatively every 24 h for 1 week using visual analogue scale. Success was analysed at 12 months based on clinical and radiographic examination. Mann-Whitney U test was used to compare age, pain scores and mean analgesic consumption between the groups. Categorical data were analysed using chi-square test. Fisher's exact test was used to assess the clinical and radiographic success and incidence of pain. Kaplan-Meier analysis was used to assess the survival of teeth. A p-value <.05 was considered as statistically significant. RESULTS: One hundred and one patients were analysed at follow up. Higher success was observed in CP (89.8%) in comparison to PP group (80.8%), but the difference was non-significant statistically (p = .202). Although no significant difference was observed in pain incidence between the groups at 24 h (p = .496), a significant difference in pain intensities was observed between groups at all the tested time intervals, with lower values reported in CP group (p < .05). CONCLUSIONS: Both CP and PP resulted in favourable outcomes in the management of cariously exposed permanent teeth with signs indicative of SIP. Given the more conservative nature of PP, it may be attempted first before proceeding to CP in such cases.

Association between concentration of active MMP-9 in pulpal blood and pulpotomy outcome in permanent mature teeth with irreversible pulpitis - a preliminary study.

AIM: To investigate the correlation between the concentration of active-matrix metalloproteinases-9 (aMMP-9) in pulpal blood and the outcome of pulpotomy in mature permanent teeth with symptomatic irreversible pulpitis (SIP). METHODOLOGY: Forty permanent molar teeth with a clinical diagnosis of SIP and normal apical tissues with periapical index (PAI) score ≤ 2 and ten permanent teeth (8 molars and two premolars) with a diagnosis of normal pulp that required root canal treatment for prosthetic reasons from patients between the ages of 15-35 years were recruited. All clinical procedures were performed under local anaesthesia and rubber dam isolation. After access opening, the coronal pulp tissue was amputated up to the canal orifice. A 100 µL volume of the pulpal blood was collected using a micropipette and transported to the laboratory. Sodium hypochlorite (2.5 %) was used as a haemostatic agent, and mineral trioxide aggregate (MTA) was used as the pulp capping material. The tooth was restored with composite at the same visit. Teeth with normal pulps were treated with single-visit root canal treatment. Patients with pulpotomy were recalled at 6 and 12 months. Outcome assessment of teeth with pulpotomy was carried out at 12 months and was categorized as success (asymptomatic patients with PAI score ≤ 2) or failure (symptomatic patients or PAI score ≥ 3). Quantification of aMMP-9 in pulpal blood was achieved using a fluorometric assay. The following statistical analyses were performed to assess the data: t-test, Fisher's exact test, kappa coefficient, non-parametric test, Wilcoxon rank-sum test, Spearman rank correlation test and receiver operating characteristic curve (ROC). RESULT: The success rate of pulpotomy was 88 % at 12-months. There was a significant difference between the median concentrations of aMMP-9 in pulpal blood of teeth with normal pulps (52 (12-96) ng mL-1 :) and SIP (193.3 (25.8-607.7) ng mL-1 :) (P = 0.0003) and successful (132.3 (25.8-548.3) ng mL-1 :) and failed cases (512.4 (334.8-607.7 ng mL-1 :) (P = 0.0015) of MTA pulpotomy. A significant association was established between aMMP-9 concentration and outcome of pulpotomy. The area under the receiver operating characteristics curve (0.9484, 95%CI) suggested excellent discriminatory power of aMMP-9 concentration in pulpal blood to predict the pulpotomy outcome. CONCLUSION: The pulpal blood concentration of aMMP-9 was significantly associated with the outcome of pulpotomy in teeth with symptomatic irreversible pulpitis, where it may be used as a potential prognostic biomarker.

Influence of occlusal and proximal caries on the outcome of full pulpotomy in permanent mandibular molar teeth with partial irreversible pulpitis: A prospective study.

AIM: To assess the influence of occlusal and proximal deep carious lesions on the outcome of full pulpotomy performed in mandibular teeth with pulpal diagnosis of symptomatic partial irreversible pulpitis. METHODOLOGY: Eighty deep carious mandibular molar teeth with clinical and radiographic diagnosis of symptomatic partial irreversible pulpitis without periapical rarefaction from patients of either gender between the age of 16-35 years were included. Depending upon the location of deep carious lesion, the teeth were distributed equally into occlusal (n = 40) and proximal caries groups (n = 40). Full pulpotomy was performed under local anaesthesia and aseptic conditions. The pulp tissue was removed until the root canal orifices, and 2.5% sodium hypochlorite (NaOCl) was applied to arrest pulpal bleeding. Mineral trioxide aggregate (MTA) was compacted over the radicular pulp. Teeth were restored with resin-modified glass ionomer cement (RMGIC) and bulk-fill composite resin. Pre- and post-operative pain was assessed at 24, 48 and 72 h using a 11-point Numerical Rating Scale (NRS). Patients were followed at 6 and 12 months for clinical and radiographic evaluation. Asymptomatic teeth without any radiographic evidence of periapical rarefaction were considered successful. The data were analysed using the Shapiro-Wilk W test, two-sample Wilcoxon rank-sum test, Pearson chi-square test, Fisher's exact test and Kappa coefficient. The significance level was predetermined at p < .05. RESULT: An intergroup comparison revealed that the pre- and post-operative pain scores at 24, 48 and 72 h were not significantly different (p > .05). At the end of follow-up period (12 months), success of full pulpotomy in occlusal and proximal caries group was 95% and 92.5%, respectively (p = .644). For both groups, the combined success rate of full pulpotomy was 93.75%. CONCLUSION: The site of carious lesions (i.e., occlusal or proximal) did not affect the clinical and radiographic outcome of full pulpotomy performed in mature permanent mandibular teeth with symptomatic partial irreversible pulpitis.

Outcome of full pulpotomy using Biodentine in adult patients with symptoms indicative of irreversible pulpitis.

AIM: To assess the outcome of full pulpotomy using Biodentine in permanent teeth with carious exposures and symptoms indicative of irreversible pulpitis. METHODOLOGY: Sixty-four permanent molar teeth with symptomatic vital pulps in 52 patients aged 19-69 years were included. Preoperative pulpal and periapical diagnosis was established. After informed consent, the tooth was anaesthetized, isolated using rubber dam and disinfected with 5% NaOCl before caries excavation; subsequently, the pulp was amputated to the level of the canal orifices. Haemostasis was achieved, and a 3-mm layer of Biodentine (Septodont, Saint-Maur-des-Fosses, France) was placed as the pulpotomy agent. Resin-modified glass-ionomer liner was placed and the tooth restored with either resin composite or amalgam, and a postoperative periapical radiograph exposed. Clinical and radiographic evaluation was completed at 6 months and 1 year postoperatively. Pain levels were scored preoperatively and 2 days post-treatment. RESULTS: Clinical signs and symptoms indicative of irreversible pulpitis were established in all teeth, and periapical rarefaction was present in nine teeth. After 2 days, 93.8% reported complete relief of pain. At 6 months, 63 of 64 attended recall with 98.4% clinical and radiographic success. At 1 year, 59 of 63 attended recall, with 100% clinical and 98.4 radiographic success. Seven of eight cases with periapical rarefaction who attended recall had improvement in the periapical index (PAI) score. A hard tissue barrier was detected radiographically in four cases. CONCLUSION: Full pulpotomy using Biodentine was a successful treatment option for cariously exposed pulps in mature permanent molar teeth with clinical signs and symptoms indicative of irreversible pulpitis, up to 1 year.

Assessment of Mineral Trioxide Aggregate pulpotomy in mature permanent teeth with carious exposures.

AIM: To assess the outcome of mineral trioxide aggregate (MTA) complete pulpotomy in permanent teeth with carious exposures. METHODOLOGY: Fifty-two permanent molar teeth with fully developed roots and vital pulps in 43 patients aged 11-51 years were included. Preoperative pulpal and periapical diagnosis was established. After informed consent, each tooth was anaesthetized, isolated with dental dam and disinfected with 5% NaOCl before caries excavation; subsequently, a full pulpotomy was performed. Haemostasis was achieved, and Grey MTA (Angelus, Londrina, Brazil) was placed as the pulpotomy agent; a moist cotton pellet was placed, and the tooth was temporized with the intermediate restorative material (IRM). Permanent restorations were placed 1 week later if the tooth was asymptomatic, and a postoperative periapical radiograph was taken. Clinical and radiographic evaluation was completed at 3 months, 6 months, 1 year and 3 years postoperatively. RESULTS: Clinical signs and symptoms suggestive of irreversible pulpitis were established in 44/52 teeth, and periapical rarefaction was present in 14 teeth. Immediate failure occurred in one tooth. The recall rate ranged from 92% at 3 months to 80.3% at 3 years, with an overall 100% clinical and 97.5% radiographic success during the first year, and 92.7% success at 3 years. All cases with periapical rarefaction were associated with improvement in the periapical index (PAI) score. Two cases had new periapical rarefaction associated with dislodgment of the permanent restoration. A hard tissue barrier was detected radiographically in 5 cases and canal narrowing in 7 cases. CONCLUSION: MTA full pulpotomy was a successful treatment option for cariously exposed pulps in mature permanent molar teeth.

Comparative evaluation of full and partial pulpotomy in permanent teeth with irreversible pulpitis: A systematic review and meta-analysis.

The purpose of this systematic review and meta-analysis is to conduct a comparative evaluation of partial and full pulpotomy techniques in cariously exposed teeth with symptoms indicative of symptomatic irreversible pulpitis. Databases such as PubMed, EMBASE, Cochrane, and Web of Science were searched. Studies evaluating and/or comparing clinical and/or radiographic success of partial and full pulpotomy in teeth diagnosed with irreversible pulpitis with a minimum of 12 months follow-up were included. The risk of bias (ROB) tool was used for the assessment of ROB. A meta-analysis was conducted to compare the healing outcome of partial and full pulpotomy. Three studies fulfilled the inclusion criteria, there was a low risk of bias in each of the five domains. Full pulpotomy had a higher success rate than partial pulpotomy, according to meta-analysis, but the difference was not statistically significant.

Total Pulpotomy Using a Newer Mineral Trioxide Aggregate for Managing Complicated Crown Fractures in Mature Permanent Incisors: A Case Report.

Crown fractures with pulp exposure in mature permanent teeth present a challenging situation that requires immediate attention. Mineral trioxide aggregate (MTA) as a sealing material after pulpotomy has proven to be a reliable treatment in these cases compared to traditional root canal therapy. This case report emphasizes the importance of early diagnosis and careful treatment planning for complicated crown fractures and concussion injuries in a mature permanent incisor of a young child. Total pulpotomy using MTA has proven to be an effective treatment for fractures in young mature incisors with pulp exposure, as evidenced by a one-year follow-up in our case, which showed no discoloration.

Outcome and Prognostic Factors for Partial and Full Pulpotomy in the Management of Spontaneous Symptomatic Pulpitis in Carious Mature Permanent Teeth: A Randomized Clinical Trial.

INTRODUCTION: The aim of this study was to compare the outcome and prognostic factors for partial and full pulpotomy in the management of mature teeth with spontaneous symptomatic pulpitis. METHODS: The study was a parallel double-blind randomized clinical trial; 200 carious mature permanent teeth with spontaneous symptomatic pulpitis were randomized using a block randomization technique to either partial pulpotomy (n = 99) or full pulpotomy (n = 101). Intraoperative assessment of the pulp under magnification was performed, hemostasis was achieved with a 2.5% sodium hypochlorite moist pellet, and NeoPUTTY (Avalon Biomed, Bradenton, FL) was the pulpotomy material. Preoperative pain levels were recorded and re-evaluated after 1 week. Clinical and radiographic evaluation was performed after 6 and 12 months. Data were analyzed using the chi-square test, the Wilcoxon rank test, and regression analysis. RESULTS: At 1 week, immediate failure occurred in 4 cases in partial pulpotomy, and 196 of 200 subjects reported pain relief and were satisfied with the treatment with no significant difference. At 6 months, 6 teeth failed in the partial pulpotomy group and 1 tooth in the full pulpotomy group, with a higher success rate for full pulpotomy (98.96 vs 89.69, P = .003). At 12 months, the recall rate was 98% (96/200). Full pulpotomy was more successful than partial pulpotomy (98.98% [98/99] vs 84.53% [82/97], P < .001). Multivariate analysis revealed that the odds of success for full pulpotomy were 13.6 times higher than partial pulpotomy. Increased age and higher time to hemostasis were significantly associated with decreased odds of success. CONCLUSIONS: Full pulpotomy has a higher success rate than partial pulpotomy in the management of spontaneous symptomatic pulpitis. Hemostasis within 4 minutes in partial pulpotomy can be set as the cutoff point beyond which further tissue removal is indicated.

Comparative Outcomes of Pulpotomy in Mature Molars with Irreversible Pulpitis: A Non-Randomized Trial Evaluating Calcified and Non-Calcified Pulp Chambers.

Introduction: This non-randomized clinical trial investigated the outcomes of full pulpotomy in adult molars with irreversible pulpitis, comparing those with calcified and non-calcified pulp chambers over 6 and 12 months. Materials and Methods: A total of 101 adult permanent molars with irreversible pulpitis, in individuals over 12 years old, were categorized based on pulp chamber calcification observed in radiographic images by two endodontists. Subsequently, full pulpotomy procedures were performed, achieving hemostasis, and applying a 2 mm layer of calcium-enriched mixture (CEM) cement as a pulp covering agent. After 48 hours, the setting of the CEM cement was verified, followed by the application of a layer of resin-modified glass-ionomer. The tooth was then restored using amalgam. Clinical and radiographic evaluations were conducted at 6-month and 1-year follow-ups by blinded endodontists. Success rates were compared using Fisher's exact test and logistic regression tests with a significance level of 0.05. Results: Among the 97 patients with 6-month and 1-year follow-ups, all achieved clinical success. Radiographic success rates were 99% at 6 months and 96.9% at 1 year, regardless of pulp calcification. In the 6-month follow-up, success rates were 98.07% for non-calcified pulp chambers and 100% for calcified pulp chambers. At the 1-year follow-up, success rates were 96.1% and 97.8%, respectively. Statistical analysis showed no significant difference in radiographic success rate between the two groups at both follow-ups (P>0.05). Conclusions: Full pulpotomy using CEM cement is a successful treatment for adult permanent teeth with calcified and non-calcified pulp chambers presenting signs and symptoms of irreversible pulpitis up to a 1-year follow-up. This study provides compelling evidence that vital pulp therapy can be effectively employed in the pulpotomy of calcified teeth, at least in the short term.

Full Pulpotomy as a Treatment for Irreversible Pulpitis in Permanent Teeth: A Systematic Review of the Literature Based on Case Reports.

The objective of this systematic review was to evaluate the current evidence of case reports where the treatment for permanent teeth with a diagnosis of irreversible pulpitis was a full pulpotomy. This study was carried out by two reviewers following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A systematic electronic search was carried out in the PubMed, Google Scholar, and Scopus databases until the year 2022 to find articles in English where the treatment for irreversible pulpitis in permanent teeth was a full pulpotomy. Literature reviews, in vitro or animal studies, abstracts, and unpublished data were excluded. The intervention, control, and outcome parameters were selected following the "Population, Interventions, Control, and Outcome" (PICO) guidelines. A total of 636 articles were found, and 14 articles were selected to be included in this review. The selected articles describe cases of full pulpotomies in mature permanent teeth with a diagnosis of irreversible pulpitis with a total of 34 (100%) successful cases, where 18 were men and 16 were women, with an average age of 19.20 ± 10.59 years and an average follow-up of 35.82 ± 26.39 months, with 12 months being the minimum follow-up time. The material used most frequently for obturation of the full pulpotomy was mineral trioxide aggregate in 16 cases (47.06%). Within the limitations of this review, full pulpotomy presents a high success rate regardless of the tooth, age, or sex as a treatment for teeth diagnosed with irreversible pulpitis.

Effect of full pulpotomy using a calcium silicate-based bioactive ceramic in adult permanent teeth with symptoms indicative of irreversible pulpitis: A retrospective study.

BACKGROUND: The authors studied the treatment effect of full pulpotomy using a calcium silicate-based bioactive ceramic in adult permanent teeth with symptoms indicative of irreversible pulpitis. METHODS: Eighty-one adult permanent teeth with symptoms indicative of irreversible pulpitis in 78 patients aged 18 through 72 years were evaluated for inclusion in the study. After caries excavation, the pulp was amputated to the level of the canal orifices. After hemostasis was achieved, calcium silicate-based bioactive ceramic was placed as the capping agent. The cavity was sealed temporarily with a glass ionomer cement and then restored with flowable resin and composite resin after 2 weeks if no positive symptoms were reported or detected. Postoperative evaluation was performed by means of clinical and radiographic examination at 2 weeks and 3, 6, and 12 months. RESULTS: Overall success rates of the procedure were 96.3% (78 of 81), 93.8% (76 of 81), 92.6% (75 of 81), and 92.6% (75 of 81) at the 2-week, 3-month, 6-month, and 12-month recall visits, respectively. Six of the 81 teeth failed and required root canal therapy. In these 6 teeth, 3 exhibited severe cold stimuli pain and spontaneous pain at the 2-week follow-up, 2 had no response to electric pulp testing with apical percussion pain and periapical rarefaction at the 3-month follow-up, and 1 tooth exhibited periapical rarefaction and labial mucosal fistula at the 6-month follow-up. CONCLUSIONS: Under the conditions of this study, full pulpotomy using a calcium silicate-based bioactive ceramic was a successful option for the treatment of adult permanent teeth with carious originated symptoms indicative of irreversible pulpitis. PRACTICAL IMPLICATIONS: Vital pulp therapy is no longer impossible for adult permanent teeth with carious originated symptoms indicative of irreversible pulpitis.

A Pilot Feasibility Study to Establish Full Pulpotomy in Mature Permanent Teeth with Symptomatic Irreversible Pulpitis as a Routine Treatment in Mexican Public Healthcare Services.

Symptomatic irreversible pulpitis is a common dental disease for which root canal treatment (RCT) has been the standard treatment. However, in many countries, RCT is considered a high-cost treatment that is not covered by public healthcare services; this forces patients to have dental extraction as their only option to relieve pain. In the last decade, several investigations have provided evidence that an alternative treatment known as full pulpotomy (FP) could be an alternative for patients who could not afford the cost of an RCT. Nevertheless, evidence is lacking on the success rate that could be obtained if it is performed in a public dental care clinic (PDCC). The present investigation has two main objectives. To be the first approach of a multicentric feasibility study to find out whether an FP performed by a general practice dentist (GPD) in a PDCC could be suitable and establish its success rate and patient satisfaction. Patients attending a PDCC with symptoms of irreversible pulpitis were invited to participate. FP was performed and followed up at 1, 3, 6, 9, and 12 months. The treatment success was assessed by combining three variables, patient satisfaction, clinical, and radiographic outcomes. Forty-one patients from 17 to 78 years old received the intervention. In total, 97.5% were completely satisfied with the treatment and were considered successful since none of the clinical or radiographic variables were present in any of the follow-ups. An FP performed by a GPD in a PDCC could be suitable as a routine treatment for symptomatic irreversible pulpitis due to the excellent success rate and patient satisfaction.

Response to Pulp Sensibility Tests after Full Pulpotomy in Permanent Mandibular Teeth with Symptomatic Irreversible Pulpitis: A Retrospective Data Analysis.

INTRODUCTION: This retrospective study analyzed the 12-month pulp sensibility (cold and electric) test response after mineral trioxide aggregate (MTA) full pulpotomy in mature permanent teeth with symptomatic irreversible pulpitis. METHODS: The records of 120 subjects from 3 completed and 1 ongoing clinical study on MTA full pulpotomy were retrieved. Ninety-six first and second mandibular molar teeth with a diagnosis of symptomatic irreversible pulpitis that underwent a single-visit MTA full pulpotomy and had completed a 12-month clinical, radiographic, and pulp sensibility (cold and electric) test follow-up were included. The data were analyzed using the Fisher exact test, the Pearson chi-square test, and the McNemar test. The significance level was predetermined at P < .05. RESULTS: A higher percentage of teeth (94.7%) responded to the electric pulp test in comparison with the cold test (13.5%) (P < .05). Sex-based responses to the electric pulp test (P > .05) and the cold test were similar (P > .05). The age-based response was similar for the electric pulp test (P > .05) but was significant for the cold test (P < .05). The tooth quadrant (left and right), the tooth (mandibular first and second molar), and the location of restoration (proximal or occlusal) did not influence the response of either the electric pulp test (P > .05) or the cold test (P > .05). At the 1-year follow-up, all the teeth that were classified as clinically and radiographically successful responded to the electric pulp test; however, only 13 teeth responded to the cold test (P = .00). CONCLUSIONS: The majority (94.7%) of the teeth that underwent MTA full pulpotomy responded to the electric pulp test at a 1-year time interval.

Pulpotomy for the Management of Irreversible Pulpitis in Mature Teeth (PIP): a feasibility study.

BACKGROUND: Progression of dental caries can result in irreversible pulpal damage. Partial irreversible pulpitis is the initial stage of this damage, confined to the coronal pulp whilst the radicular pulp shows little or no sign of infection. Preserving the pulp with sustained vitality and developing minimally invasive biologically based therapies are key themes within contemporary clinical practice. However, root canal treatment involving complete removal of the pulp is often the only option (other than extraction) given to patients with irreversible pulpitis, with substantial NHS and patient incurred costs. The European Society of Endodontology's (ESE 2019) recent consensus statement recommends full pulpotomy, where the inflamed coronal pulp is removed with the goal of keeping the radicular pulp vital, as a more minimally invasive technique, potentially avoiding complex root canal treatment. Although this technique may be provided in secondary care, it has not been routinely implemented or evaluated in UK General Dental Practice. METHOD: This feasibility study aims to identify and assess in a primary care setting the training needs of general dental practitioners and clinical fidelity of the full pulpotomy intervention, estimate likely eligible patient pool and develop recruitment materials ahead of the main randomised controlled trial comparing the clinical and cost-effectiveness of full pulpotomy compared to root canal treatment in pre/molar teeth of adults 16 years and older showing signs indicative of irreversible pulpitis. The feasibility study will recruit and train 10 primary care dentists in the full pulpotomy technique. Dentists will recruit and provide full pulpotomy to 40 participants (four per practice) with indications of partial irreversible pulpitis. DISCUSSION: The Pulpotomy for the Management of Irreversible Pulpitis in Mature Teeth (PIP) study will address the lack of high-quality evidence in the treatment of irreversible pulpitis, to aid dental practitioners, patients and policymakers in their decision-making. The PIP feasibility study will inform the main study on the practicality of providing both training and provision of the full pulpotomy technique in general dental practice.

BiodentineTM Full Pulpotomy in Mature Permanent Teeth with Irreversible Pulpitis and Apical Periodontitis.

Vital pulp therapy, including direct pulp capping and partial and full pulpotomy, is primarily indicated for immature or mature permanent teeth with reversible pulpitis. Mature permanent teeth with irreversible pulpitis are frequently treated with root canal therapy. This report presents two cases of full pulpotomy using BiodentineTM in mature permanent teeth with irreversible pulpitis and acute apical periodontitis. The periapical radiograph illustrated a deep carious lesion extended to the pulp with apical radiolucency lesion or widened periodontal ligament space. Full pulpotomy with a tricalcium silicate-based cement was chosen as the definitive treatment. After decayed tissue excavation under a rubber dam, the exposed pulp tissue was amputated to the level of the canal orifice with a new sterile bur. BiodentineTM was applied as the pulp capping agent after hemostasis was obtained and for temporary restoration. The clinical signs disappeared quickly after the treatment. After one month, the coronal part of the temporary restoration was removed, and a composite resin was placed over the capping agent as a final restoration. At two-year follow-ups, the teeth were asymptomatic. Radiographs showed healing of the periapical lesion and periodontal ligament. BiodentineTM full pulpotomy of mature permanent teeth with irreversible pulpitis and apical periodontitis can be an alternative option to root canal therapy.

A Combination of Full Pulpotomy and Chairside CAD/CAM Endocrown to Treat Teeth with Deep Carious Lesions and Pulpitis in a Single Session: A Preliminary Study.

A higher chance of carrying out a successful full pulpotomy may depend on whether the coronal restoration can be completed within a single appointment. The development of chairside CAD/CAM (Computer Aided Design and Manufacturing) technology has made it possible to carry out indirect restoration of endodontically treated teeth in a single session. This study aimed to evaluate the long-term outcome of a full pulpotomy with Biodentine™ immediately covered with a chairside CAD/CAM endocrown on teeth affected by pulpitis and deep carious lesions. The investigation involved a cohort of 30 molars that were treated by pulpotomy and CAD/CAM endocrown. Clinical and radiological examinations were scheduled at 1, 6, and 12 months postoperatively. Overall, all treatments were effective at any time during the follow-up. The results of this study need to be confirmed with a longer-term follow-up to allow for comparison with the literature. This original combination of endodontic and restorative treatments provides an Endo-prosthetic continuum in a single session, with the objective of long-term success in terms of tooth health.

Long-term Outcomes of Full Pulpotomy in Permanent Molars for Patients Treated in a Single, Short Session under Special Conditions.

INTRODUCTION: Endodontic procedures for patients requiring treatment in a single, short session need to be validated. This study aimed at evaluating the long-term outcome of full pulpotomy in permanent molars performed with reinforced zinc oxide-eugenol cement (Intermediate Restorative Material [IRM], Dentsply Sirona, Versailles, France) immediately restored using stainless steel crowns under general anesthesia. METHODS: The absence of clinical signs and symptoms and the evolution of the periapical index between the treatment date and the longest follow-up time were used to grade the pulpotomy outcome as "effective," "uncertain," or "ineffective." The impact of different criteria on the pulpotomy outcome was tested (ie, the etiology of the lesion, tooth maturity, endodontic difficulty related to the coronal shape and the root canal shape, and endodontic difficulty related to the radiographic root canal appearance). RESULTS: Among the 608 teeth (338 patients) treated in a single session with IRM full pulpotomy and stainless steel preformed crowns, 263 (143 patients) were evaluated after a median follow-up period of 24 months. Overall, 89% of the pulpotomies were effective, 7.6% were of uncertain outcome, and 3.4% were ineffective. No tested criteria influenced the rate of effectiveness. CONCLUSIONS: Long-term outcomes of IRM pulpotomy are similar to those of calcium silicate-based cement pulpotomy observed in the literature. This procedure should not be restricted to patients treated under general anesthesia because it is relevant for all special conditions that impose the provision of endodontic treatment in a single, short session, such as dental care emergencies during humanitarian crises or pandemic periods.
