Randomized Controlled Trial
AIM
To compare and evaluate the clinical and radiographic performance, post-operative pain, and anti-inflammatory intake after partial pulpotomy (PP) with calcium hydroxide (CH), mineral trioxide aggregate (MTA), Biodentine (BD), and Emdogain (EMD) as pulp capping agents in mature permanent molars with definitive diagnosis of reversible pulpitis.
MATERIALS AND METHODS
As part of this prospective, randomized clinical trial with four parallel arms (CTRI Registration No.: CTRI/2020/11/029329 dated 24/11/2020), hundred and ten permanent molars with a clinical diagnosis of reversible pulpitis and normal apical tissues, from patients between the ages of 15 and 45 years, were recruited and randomly assigned to four groups-CH, MTA, BD, and EMD. Operative procedure was performed under local anesthesia and dental dam isolation. After carious pulpal exposure, 2 mm of superficially inflamed coronal pulp tissue was amputated and either of the four pulp capping materials was placed. The outcome assessment was carried out at 1, 3, 6, and 12 month(s) and was categorized as success (asymptomatic patients with PAI score = 1) or failure (symptomatic patients or PAI score > 1).
RESULTS
There was a significant difference in post-operative pain and anti-inflammatory medication intake after partial pulpotomy with Emdogain vis-à-vis other three capping agents. No difference in both clinical and radiographic performances was observed among the four capping agents.
CONCLUSION
Partial pulpotomy when performed following evidence-based guidelines results in high success rates regardless of capping agent employed. EMD can be considered a valid and suitable pulp capping agent in PP.
CLINICAL RELEVANCE
Meticulous examination and removal of superficially inflamed pulp under magnification and complete asepsis lead to successful pulpal healing regardless of capping agent employed.

BACKGROUND
Epigenetic factors influence the odontogenic differentiation of dental pulp stem cells and play indispensable roles during tooth development. Some microRNAs can epigenetically regulate other epigenetic factors like DNA methyltransferases and histone modification enzymes, functioning as epigenetic-microRNAs. In our previous study, microarray analysis suggested microRNA-93-5p (miR-93-5p) was differentially expressed during the bell stage in human tooth germ. Prediction tools indicated that miR-93-5p may target lysine-specific demethylase 6B (KDM6B). Therefore, we explored the role of miR-93-5p as an epi-miRNA in tooth development and further investigated the underlying mechanisms of miR-93-5p in regulating odontogenic differentiation and dentin formation.
METHODS
The expression pattern of miR-93-5p and KDM6B of dental pulp stem cells (DPSCs) was examined during tooth development and odontogenic differentiation. Dual luciferase reporter and ChIP-qPCR assay were used to validate the target and downstream regulatory genes of miR-93-5p in human DPSCs (hDPSCs). Histological analyses and qPCR assays were conducted for investigating the effects of miR-93-5p mimic and inhibitor on odontogenic differentiation of hDPSCs. A pulpotomy rat model was further established, microCT and histological analyses were performed to explore the effects of KDM6B-overexpression and miR-93-5p inhibition on the formation of tertiary dentin.
RESULTS
The expression level of miR-93-5p decreased as odontoblast differentiated, in parallel with elevated expression of histone demethylase KDM6B. In hDPSCs, miR-93-5p overexpression inhibited the odontogenic differentiation and vice versa. MiR-93-5p targeted 3' untranslated region (UTR) of KDM6B, thereby inhibiting its protein translation. Furthermore, KDM6B bound the promoter region of BMP2 to demethylate H3K27me3 marks and thus upregulated BMP2 transcription. In the rat pulpotomy model, KDM6B-overexpression or miR-93-5p inhibition suppressed H3K27me3 level in DPSCs and consequently promoted the formation of tertiary dentin.
CONCLUSIONS
MiR-93-5p targets epigenetic regulator KDM6B and regulates H3K27me3 marks on BMP2 promoters, thus modulating the odontogenic differentiation of DPSCs and dentin formation.

Review
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.

Review
Pulpotomy has been used in primary teeth and immature permanent teeth. However, with the advent of new bioactive material, the procedure is shifting towards permanent teeth with mature apices of roots. The objective of this systematic review was to evaluate the success of pulpotomy on mature permanent teeth with acute irreversible pulpitis and to compare it with root canal treatment or between the effectiveness of the bioactive material used. The following databases were searched: PubMed, Cochrane Library: Cochrane Central Register of Controlled Trials, Embase, ClinicalTrials.gov, International Clinical Trials Registry Platform. After using the keywords predefined, the electronic search yielded a total of 86 articles. After undergoing a thorough screening and eligibility process, only four articles were finally selected. Unexpectedly, pulpotomy demonstrated a better tendency for success in such cases over the years. This shows that pulpotomy is not inferior to root canal treatment for permanent treatment of irreversible pulpitis. In addition, the results obtained showed that pulpotomy is rapid, biologically reliable and more cost-effective in all situations compared to root canal therapy. Complete pulpotomy appears to have a high success rate as a permanent treatment of irreversible pulpitis and could be considered as an alternative to root canal therapy. Pulpotomy is not inferior to root canal treatment for a permanent treatment of irreversible pulpitis. In addition, the results obtained have shown that complete pulpotomy is faster and more profitable in all situations compared to root canal treatment. Furthermore, with the advent of new so-called bioactive materials, the use of this therapeutic is increasingly considered. This is why a review based on studies of reliable articles is above all necessary to be able to generalise the indication of this therapy.

Meta-Analysis
The purpose of this study was to present an evidence-based guideline for primary teeth with deep caries or trauma requiring vital pulp therapies (VPT). A systematic review/meta-analysis on vital primary teeth resulting from trauma or caries was conducted using GRADE to assess the certainty of evidence for clinical recommendations. A decision tree was provided for choosing VPTs. No articles on trauma VPT were found. For VPT in primary teeth with deep caries, indirect pulp treatment (IPT) or pulpotomy using the calcium silicate cement (mineral trioxide aggregate [MTA] or Biodentine) show increased success over using direct pulp capping (DPC) and other pulpotomies. Different liners do not affect IPT success (high certainty) or DPC capping agents' success (very low certainty) after 24 months. It is strongly recommended, with high certainty from 24-month data, that calcium silicate cement pulpotomy is preferred over formocresol, ferric sulfate, zinc oxide eugenol pulpotomy, and other pulpotomies. Using selective caries removal and IPT for deep caries is strongly recommended with moderate certainty over complete and stepwise removal. Statistically, this results in significantly fewer pulp exposures. No caries removal and Hall technique crown may be used when indicated (moderate certainty at 24 months). For vital primary incisors with deep caries, pulpotomy was significantly better statistically than pulpectomy. Teeth diagnosed with/without reversible pulpitis pain showed comparable success after 12 months of treatment by IPT or calcium silicate cement pulpotomy. The following had little or no significant effect on MTA pulpotomy success: coronal pulp removal methods; irrigation solution; method to control hemorrhage; base over MTA; treatment in one or two visits; anterior or posterior teeth. Indirect pulp treatment or calcium silicate cement pulpotomy is likely to increase vital pulp therapy success over other VPTs such as direct pulp capping and other pulpotomies after 24 months (moderate certainty).

Randomized Controlled Trial
BACKGROUND
Pulpotomy as a minimally invasive pulp therapy technique is the treatment of choice for carious pulp exposures, however many pediatric dentists perform pulpectomies in vital primary incisors. The aim of this split mouth randomized controlled study was to compare formocresol pulpotomy and zinc-oxide and eugenol pulpectomy in the treatment of vital pulp exposure in primary incisors.
METHODS
Contralateral pairs of incisors were randomly assigned to receive pulpotomy or pulpectomy in children aging from 18 to 66 months old and were followed up for 12 months.
RESULTS
39 pairs of incisors were included. Clinical and radiographical success rates showed no statistical significant difference (p = 1, p = 0.8 respectively). Relative risk measures for clinical success rates (RR = 1.03, 95%CI 0.87 to 1.23) and for radiographic success rates (RR = 1.03, 95%CI 0.83 to 1.29) with CIs including number one showing no difference between the two groups. The Survival rate using Kaplan-Meier survival analysis score showed 82% for pulpotomy and 74% for pulpectomy at 12 months (P = 0.2).
CONCLUSIONS
Both pulpotomy and pulpectomy techniques can be used successfully in the treatment of carious vital pulp exposure in primary incisors.

Randomized Controlled Trial
OBJECTIVES
Pulpotomy is the most commonly performed treatment for asymptomatic primary molars with exposed dental pulp. This study aimed to assess the clinical /radiographic success of diode laser pulpotomy with mineral trioxide aggregate (MTA), calcium hydroxide (CH), and calcium-enriched mixture (CEM) cement as pulp capping agents.
METHODS
This split-mouth randomized clinical trial was conducted initially on 34 children aged 3-8 years but 4 patients left the study before the first follow-up visit and the study was accomplished and analyzed with 30 cases. The patients had at least 3 first/second molars with deep caries that in radiographic evaluation revealed that they required pulpotomy. Following pulpotomy, the pulp stump was irradiated with diode laser (noncontact mode, 632 nm, 30 mW power) as photobiomodulation mode. Pulp tissue was then capped with MTA, CH, or CEM cement (n = 30 in each group). Reinforced zinc oxide eugenol was applied over the capping agent, and the teeth were restored with stainless steel crowns. Teeth were clinically/radiographically assessed at 6, 12, 18, and 36 months, after treatment. Data were analyzed by Cochran and McNemar tests.
RESULTS
All 30 patients showed up for clinical/radiographic follow-ups for up to 36 months. Regarding clinical outcomes, the 6-, 12-, 18-, and 36-month success rates of all experimental groups were nearly similar with no significant difference (p > .05). Regarding radiographic outcomes, the 6-month success rates were similar among the groups (p > .05); however, the 12-, 18-, and 36-month outcomes of CEM and MTA groups were similar but significantly superior to that of CH group (p < .05).
CONCLUSION
Diode laser irradiation and subsequent capping of pulp tissue with MTA or CEM cement can be employed for pulpotomy of primary molars.

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.

Review
BACKGROUND
Pulpotomy procedures aiming to preserve and regenerate the dentin-pulp complex have recently increased exponentially due to developments in the field of biomaterials and tissue engineering in primary and permanent teeth. Although the number of studies in this domain has increased, there is still scarcity of evidence in the current literature.
OBJECTIVES
(1) Report the methods of outcome assessment of pulpotomy clinical trials in both primary and permanent teeth; (2) Identify the various bioactive agents and biodegradable scaffolds used in pulpotomy clinical trials in both primary and permanent teeth.
MATERIALS AND METHODS
A scoping review of the literature was performed, including a search of primary studies on PubMed, Scopus, Web of Science, ProQuest and Clinicaltrials.gov. A search for controlled trials or randomized controlled trials published between 2012 and 2023 involving primary or permanent teeth receiving partial or full pulpotomy procedures using bioactive/regenerative capping materials was performed.
RESULTS
127 studies out of 1038 articles fulfilled all the inclusion criteria and were included in the current scoping review. More than 90% of the studies assessed clinical and radiographic outcomes. Histological, microbiological, or inflammatory outcomes were measured in only 9.4% of all included studies. Majority of the studies (67.7%) involved primary teeth. 119 studies used non-degradable bioactive cements, while biodegradable scaffolds were used by 32 studies, natural derivates and plant extracts studies were used in only 7 studies. Between 2012 (4 studies) and 2023 (11 studies), there was a general increase in the number of articles published. India, Egypt, Turkey, and Iran were found to have the highest total number of articles published (28, 28,16 and 10 respectively).
CONCLUSIONS
Pulpotomy studies in both primary and permanent teeth relied mainly on subjective clinical and radiographic outcome assessment methods and seldom analyzed pulpal inflammatory status objectively. The use of biodegradable scaffolds for pulpotomy treatments has been increasing with an apparent global distribution of most of these studies in low- to middle-income countries. However, the development of a set of predictable outcome measures as well as long-term evidence from well conducted clinical trials for novel pulpotomy dressing materials are still required.

Meta-Analysis Review
BACKGROUND
This systematic review aimed to investigate whether vital pulp therapy and root canal treatment (RCT) promote different postoperative pain.
STUDIES REVIEWED
The authors searched PubMed, Cochrane Library, Embase, and Latin American and Caribbean Health Sciences Literature databases for studies published through June 30, 2022. The authors included randomized clinical trials if they reported on the assessment of postoperative pain after direct pulp capping, partial pulpotomy, pulpotomy, or single-visit RCT. The authors assessed the frequency of no, mild, moderate, and severe postoperative pain. They conducted meta-analyses to compare postoperative pain after full pulpotomy (PULP) and RCT.
RESULTS
The qualitative synthesis included 57 studies, and the authors conducted meta-analysis of 3. PULP leads to more asymptomatic cases (relative risk [RR], 1.06; 95% CI, 1.01 to 1.11; P < .01; I = 67%) and to a lower occurrence of mild (RR, 0.89; 95% CI, 0.79 to 0.99; P < .04; I = 37%) and moderate (RR, 0.70; 95% CI, 0.51 to 0.95; P < .02; I = 57%) postoperative pain than RCT. The frequency of severe pain was very low for both vital pulp therapy and RCT. Moderate to severe postoperative pain was more common at 48 hours through 72 hours after RCT and up to 36 hours after PULP. Pain intensity after PULP was higher using calcium-enriched material compared with using mineral trioxide aggregate at 12, 18, and 36 hours (P < .001).
PRACTICAL IMPLICATIONS
PULP showed a significantly higher incidence of no pain and a lower incidence of mild and moderate pain than single-visit RCT. Clinical decisions for RCT or PULP should not be based on differences in postoperative pain. When analgesia is indicated, it probably should be limited to a short time after PULP.
