Abstract
BACKGROUND To assess and compare the effectiveness of propolis mouthwash with chlorhexidine mouthwash in the reduction of plaque and gingivitis. METHODS A single centre, latin-square cross-over, double masked, randomized controlled clinical trial was conducted on 45 chronic generalized gingivitis subjects who were chosen from the dental clinic of MAHSA University, Malaysia. A total of 45 subjects were randomly assigned into one of the three different groups (n = 15 each) using a computer-generated random allocation sequence: Group A Propolis mouthwash; Group B Chlorhexidine mouthwash; and Group C Placebo mouthwash. Supragingival plaque and gingival inflammation were assessed by full mouth Plaque index (PI) and gingival index (GI) at baseline and after 21 days. The study was divided into three phases, each phase lasted for 21 days separated by a washout period of 15 days in between them. Groups A, B and C were treated with 0.2% Propolis, Chlorhexidine, and Placebo mouthwash, respectively, in phase I. The study subjects were instructed to use the assigned mouthwash twice daily for 1 min for 21 days. On day 22nd, the subjects were recalled for measurement of PI and GI. After phase I, mouthwash was crossed over as dictated by the Latin square design in phase II and III. RESULTS At baseline, intergroup comparison revealed no statistically significant difference between Groups A, B and C (p > 0.05). On day 21, one-way ANOVA revealed statistically significant difference between the three groups for PI (p < 0.001) and GI (p < 0.001). Bonferroni post-hoc test showed statistically significant difference between Propolis and Chlorhexidine mouthwash (P < 0.001), with higher reduction in the mean plaque and gingival scores in propolis group compared to chlorhexidine and placebo groups. CONCLUSIONS Propolis mouthwash demonstrated significant improvement in gingival health and plaque reduction. Thus, it could be used as an effective herbal mouthwash alternative to chlorhexidine mouthwash. TRIAL REGISTRATION The trial was retrospectively registered on 25/07/2019 at clinicaltrials.gov and its identifier is NCT04032548.

Abstract
Nowadays, there is an increasing prevalence of bone diseases and defects caused by trauma, cancers, infections, and degenerative and inflammatory conditions. The restoration of bone tissue lost due to trauma, fractures, or surgical removal resulting from locally invasive pathologies requires bone regeneration. As an alternative to conventional treatments, sustainable materials based on natural products, such as honeybee-derived products (honey, propolis, royal jelly, bee pollen, beeswax, and bee venom), could be considered. Honeybee-derived products, particularly honey, have long been recognized for their healing properties. There are a mixture of phytochemicals that offer bone protection through their antimicrobial, antioxidant, and anti-inflammatory properties. This review aims to summarize the current evidence regarding the effects of honeybee-derived products on bone regeneration. In conclusion, honey, propolis, royal jelly, beeswax, and bee venom can potentially serve as natural products for promoting bone health.

Abstract
BACKGROUND Oral aphthous stomatitis is a chronic inflammatory condition. Numerous medications have been investigated to treat the symptoms of the disease. However, these days patients prefer herbal medicines due to lower side effects. Considering the anti-inflammatory, analgesic, and anti-oxidant properties of Caffeic acid and its few side effects, the aim of this study was to assess the impact of Caffeic acid on recurrent aphthous stomatitis (RAS). investigating the effect of caffeic acid mucoadhesive tablets on the size and pain intensity of the aphthous lesions. METHODS in this double-blinded clinical trial study, 47 patients who met the inclusion criteria were selected by convenient sampling method. The patients were assigned to two groups randomly; the control group (placebo recipients) and the intervention group (Caffeic acid recipients). Patients were followed up for 7 days following the intervention. The diameter of the inflammatory lesion was measured in millimeters, and the pain intensity was recorded based on the VAS scale (Visual Analogue Scale). This trial was approved by the medical ethics committee of Mazandaran University of Medical Sciences (Ethical code: IR.MAZUMS.REC.1401.261) and received IRCT code of IRCT20220815055700N1on 03/09/2022. RESULTS the diameter of the lesion in both groups decreased over time, and there was no significant difference between the intervention and control groups, except on the fifth day when the diameter of the lesion was significantly greater in the control group (P = 0.012). From the second day, the control group's average pain intensity was significantly higher than the intervention group's pain intensity (P < 0.05). CONCLUSIONS when comparing mucoadhesive tablets containing Caffeic acid and placebo, the findings demonstrated that Caffeic acid has a significant efficacy in reducing aphthous lesions' diameter and pain intensity of the patients and are suggested for palliative oral aphthous lesions treatment since they showed significant anti-inflammatory and analgesic effects on recurrent aphthous stomatitis.

Abstract
BACKGROUND Pulpotomy is a treatment option for the preservation of pulp vitality in primary teeth with extensive caries. Propolis is a natural resinous substance with optimal antimicrobial, anti-inflammatory, and immune-regulatory properties. Thus, this study aimed to compare the cytotoxic and apoptosis-inducing effects of mineral trioxide aggregate (MTA), propolis, and MTA-propolis on immature dental pulp stem cells (IDPSCs). METHODS In this in vitro, experimental study, primary IDPSCs were exposed to propolis, MTA, and MTA-propolis for 24 and 72-h. The cytotoxicity and apoptosis-inducing effects were evaluated using the methyl thiazolyl tetrazolium (MTT) assay and flow cytometry, respectively. Data were analyzed using ANOVA and Tukey's test at 0.05 level of significance. RESULTS The cytotoxicity of MTA and MTA-propolis was higher than that of propolis alone at both 24/48 h. In addition, all tested concentrations showed higher biocompatibility at 72-h compared with 24-h (P < 0.0001). In the assessment of apoptosis, propolis-MTA showed higher cell viability compared with other materials (P < 0.0001). CONCLUSION Propolis-MTA showed higher biocompatibility than MTA. Addition of propolis to MTA improved cell proliferation in the first 24-h. Also, the cytotoxicity of propolis was lower than other materials in the first 24-h. Thus, propolis may serve as a promising pulp capping agent given that its other properties are approved.

Abstract
Aims Clinical and radiographic evaluation of mineral trioxide aggregate (MTA), TheraCal LC, and propolis when used as an indirect pulp capping agent in primary teeth over a period of 6 months. Materials and methods A total of 42 primary molar teeth from children aged 4-10 years were chosen for the study. The teeth were divided equally into three groups (group I: MTA, group II: light cured calcium silicate, and group III: propolis). The teeth were followed up clinically and radiographically at 3 and 6 months. The teeth that showed successful treatment outcomes clinically and radiographically were evaluated for the amount of dentin bridge formed at the end of 3 and 6 months, which was measured using CorelDRAW software. The data obtained was analyzed statistically using Statistical Package for the Social Sciences (SPSS) version 21. Results The mean change in dentin thickness from baseline to 3 months in group II was found to be the highest, followed by groups I and III. The mean change in dentin thickness from 3 months to 6 months was highest in group I, followed by groups III and II. The mean change in dentin thickness from baseline to 6 months in group II was found to be significantly higher than that of group I, followed by group III. Conclusion Clinically and radiographically, all three materials showed favorable outcomes when used as an indirect pulp capping material with significant reparative dentin formation. The highest amount of dentin deposition was recorded with light-cured calcium silicate, followed by MTA and propolis, respectively. How to cite this article Saikia D, Yadav G, Saha S, et al.

Abstract
Aims To histologically assess and compare formocresol (FC), platelet-rich fibrin (PRF), and hesperidin (HPN) as pulpotomy agents in dogs. Materials and Methods Pulpotomy was attempted from the buccal surface (class V) of 48 teeth in three mongrel dogs (Canis Lupus). Cavities were randomly allocated for three groups (n = 16) according to the pulpotomy agent used; (group I: FC (control), group II: PRF, and group III: HPN). All cavities were then sealed with zinc oxide eugenol followed by resin-modified glass ionomer restoration. Two months later, dogs were euthanized; the specimens were obtained and prepared for histological assessment followed by statistical analysis. Results HPN specimens showed the best dentin bridge formation and the least inflammatory signs and pulp disorganization. Followed without statistically significant difference by PRF (P ≥ 0.05). Both of HPN and PRF, however, showed a significant difference statistically (P ≤ 0.05) to FC that showed no dentin bridging with more pronounced inflammation, necrosis, and pulp disorganization. Conclusions For pulpotomy, HPN and PRF seemed histologically to be good substitutes for FC in the dog model.

Abstract
This systematic review synthesizes the existing evidence in the literature regarding the association of propolis with controlled delivery systems (DDSs) and its potential therapeutic action in dental medicine. Two independent reviewers performed a literature search up to 1 June 2023 in five databases: PubMed/Medline, Web of Science, Cochrane Library, Scopus, and Embase, to identify the eligible studies. Clinical, in situ, and in vitro studies that investigated the incorporation of propolis as the main agent in DDSs for dental medicine were included in this study. Review articles, clinical cases, theses, dissertations, conference abstracts, and studies that had no application in dentistry were excluded. A total of 2019 records were initially identified. After carefully examining 21 full-text articles, 12 in vitro studies, 4 clinical, 1 animal model, and 3 in vivo and in vitro studies were included (n = 21). Relevant data were extracted from the included studies and analyzed qualitatively. The use of propolis has been reported in cariology, endodontics, periodontics, stomatology, and dental implants. Propolis has shown non-cytotoxic, osteoinductive, antimicrobial, and anti-inflammatory properties. Moreover, propolis can be released from DDS for prolonged periods, presenting biocompatibility, safety, and potential advantage for applications in dental medicine.

Abstract
OBJECTIVE To explore the potential for development of Thai propolis extract as a pulp capping agent to suppress pulpal inflammation from dental pulp infections. This study aimed to examine the anti-inflammatory effect of the propolis extract on the arachidonic acid pathway, activated by interleukin (IL)-1β, in cultured human dental pulp cells. METHODOLOGY Dental pulp cells, isolated from three freshly extracted third molars, were first characterized for their mesenchymal origin and treated with 10 ng/ml of IL-1β in the presence or absence of non-toxic concentrations of the extract from 0.08 to 1.25 mg/ml, as determined by the PrestoBlue cytotoxic assay. Total RNA was harvested and analyzed for mRNA expressions of 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2). Western blot hybridization was performed to investigate COX-2 protein expression. Culture supernatants were assayed for released prostaglandin E2 levels. Immunofluorescence was conducted to determine involvement of nuclear factor-kappaB (NF-kB) in the inhibitory effect of the extract. RESULTS Stimulation of the pulp cells with IL-1β resulted in the activation of arachidonic acid metabolism via COX-2, but not 5-LOX. Incubation with various non-toxic concentrations of the propolis extract significantly inhibited upregulated COX-2 mRNA and protein expressions upon treatment with IL-1β (p<0.05), resulting in a significant decrease in elevated PGE2 levels (p<0.05). Nuclear translocation of the p50 and the p65 subunits of NF-kB upon treatment with IL-1β was also blocked by incubation with the extract. CONCLUSIONS Upregulated COX-2 expression and enhanced PGE2 synthesis upon treatment with IL-1β in human dental pulp cells were suppressed by incubation with non-toxic doses of Thai propolis extract via involvement of the NF-kB activation. This extract could be therapeutically used as a pulp capping material due to its anti-inflammatory properties.

Abstract
OBJECTIVES Successful endodontic therapy is based on the reduction of infecting bacteria by cleaning, shaping, and disinfecting of the root canal system, thus the use of intracanal dressing is necessary for optimal success of root canal treatment. This study was designed to evaluate the effect of chitosan and propolis as intracanal medicaments against Enterococcus faecalis compared to calcium hydroxide in primary root canals. MATERIAL AND METHODS Ninety-six extracted primary second molars were collected. Teeth preparation was completed to size 30 K-file. They were randomly divided into four groups; (A): chitosan, (B): propolis, (C): calcium hydroxide, and (D): control group (saline). The tooth specimens were inoculated with E. faecalis. Then, tested materials were applied for all groups in accordance to the groups each tooth belonged to. Following this, the bacterial colonies were counted after 24 h, 72 h, and 1 week of applying dressing materials and incubation. Finally, one-way analysis of variance and Fisher's least significant difference tests were used for statistical comparisons between the groups at a significance level of .05. RESULTS No statistically significant difference was found between groups A, B, and C for both 24 h and a week (p ≥ .05). Yet, a statistical difference between groups A, B, C, and D after 72 h and 1 week were seen (p ≤ .05). CONCLUSIONS Chitosan and propolis medicaments were as effective as calcium hydroxide against E. faecalis in primary root canal treatment and might be considered as an alternative dressing material between treatment sessions.

Abstract
Objectives In this study, natural substances were introduced as primary dental pulp caps for use in pulp therapy, and the antimicrobial and cytotoxic properties of these substances were investigated. Materials and Methods In this in vitro study, the antimicrobial properties of calcium-enriched mixture (CEM) cement, propolis, and propolis individually combined with the extracts of several medicinal plants were investigated against Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. Then, the cytotoxicity of each substance or mixture against pulp stem cells extracted from 30 primary healthy teeth was evaluated at 4 concentrations. Data were gathered via observation, and optical density values were obtained using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) test and recorded. SPSS software version 23 was used to analyze the data. Data were evaluated using 2-way analysis of variance and the Tukey test. Results Regarding antimicrobial properties, thyme alone and thyme + propolis had the lowest minimum inhibitory concentrations (MICs) against the growth of S. aureus, E. coli, and P. aeruginosa bacteria. For E. faecalis, thyme + propolis had the lowest MIC, followed by thyme alone. At 24 and 72 hours, thyme + propolis, CEM cement, and propolis had the greatest bioviability in the primary dental pulp stem cells, and lavender + propolis had the lowest bioviability.

Abstract
Herbal products are gaining popularity in dental and medical practice nowadays due to their biocompatibility, higher antimicrobial activity, antioxidant and anti-inflammatory properties. Herbal medicine has experienced rapid growth in recent years due to its beneficial properties, ease of availability, and lack of side effects. As pathogenic bacteria become more resistant to antibiotics and chemotherapeutic agents, researchers are becoming more interested in alternative products and treatment choices for oral diseases. As a result, natural phytochemicals separated from plants and utilized in traditional medicine are suitable substitutes for synthetic chemicals. The aim of this review article is to list and understand several herbal alternatives that are currently accessible for use as efficient endodontic medicaments. The herbal products used in endodontics have several advantages, including safety, ease of use, increased storability, low cost, and a lack of microbial tolerance. However, preclinical and clinical testing and interactions with other materials and adverse effects are required for these herbal products.

Abstract
Propolis, a natural resinous mixture produced by honey bees is poised with diverse biological activities. Owing to the presence of flavonoids, phenolic acids, terpenes, and sesquiterpenes, propolis has garnered versatile applications in pharmaceutical industry. The biopharmaceutical issues associated with propolis often beset its use as being too hydrophobic in nature; it is not absorbed in the body well. To combat the problem, various nanotechnological approaches for the development of novel drug delivery systems are generally applied to improve its bioavailability. This paradigm shift and transition of conventional propolis to nanopropolis are evident from the literature wherein a multitude of studies are available on nanopropolis with improved bioavailability profile. These approaches include preparation of gold nanoparticles, silver nanoparticles, magnetic nanoparticles, liposomes, liquid crystalline formulations, solid lipid nanoparticles, mesoporous silica nanoparticles, etc. Nanopropolis has further been explored to assess the potential benefits of propolis for the development of futuristic useful products such as sunscreens, creams, mouthwashes, toothpastes, and nutritional supplements with improved solubility, bioavailability, and penetration profiles. However, more high-quality clinical studies assessing the effects of propolis either alone or in combination with synthetic drugs as well as natural products are warranted and its safety needs to be firmly established.

Abstract
Background The study aims to investigate the pulp and periapical reaction and healing after capping with EndoSequence Root Repair Material (ERRM) combined with low-level laser application. Methods In 6 rabbits, pulps were exposed via class V, half of the samples received a low-level diode laser at 980 nm. Thereafter, cavities were capped with regular-set ERRM. The specimens were processed for histomorphological examination after 2 weeks and two months. Results After 2 weeks, images show mild inflammation and organized odontoblasts in lased group. The non-lased group shows more severe inflammation. The predentin thickness was thicker in the lased group with statistical significance (p < 0.05). After 2 months, inflammatory cells were sparse in both lased and non-lased groups. In the periapical area, group one showed dilated blood vessels and thick fibrous connective tissues. In group two, there were more numerous maturations of PDL fibers with scattered inflammatory cells and congested blood vessel. Conclusions Using low-level laser therapy in combination with ERRM for pulp capping shortens the inflammatory phase and enhances healing.

Abstract
Aim and objective To evaluate the clinical efficacy of propolis as pulpotomy medicament in human primary molars. Materials and methods This randomized controlled trial is a two-arm, parallel group study with blinded outcome assessment. The study included a total of 60 primary molars that require pulpotomy treatment in 4- 8-year old children. Teeth were assigned to two groups randomly: Propolis (Test group); Mineral trioxide aggregate (MTA) (Control group). All the pulpotomized teeth were given stainless steel crowns and the teeth were evaluated clinically and radiographically at 6, 12, and 24 months to grade them as either success or failure. Chi-square test was employed to analyze the data. Results Success rates of pulpotomy with propolis and MTA were 80% and 93.1% respectively at 24 months of follow-up interval. Propolis has shown success rates of 90% and 80% at 6- and 12-month follow-up, while MTA has shown a consistent success rate of 93.1% at all the follow-up intervals. The difference in success rate between the groups at all the time intervals is statistically nonsignificant. Conclusion Propolis has demonstrated a clinically acceptable success rate comparable to MTA as pulpotomy medicament in primary teeth. Clinical significance Biocompatible materials with regenerative potential have drawn the momentum in vital pulp therapy. In this regard, MTA has been emerged as most successful material, but its high cost has limited its use. Hence, there is an absolute need of cost-effective pulpotomy material with regenerative potential. This study provides an evidence that propolis has clinically acceptable success rate as pulpotomy medicament. Considering its low cost and ready availability, it can be recommended as a cost-effective alternative for primary teeth pulpotomy.

Abstract
For years, apical microleakage has been considered the main factor in endodontic failure therapy. Sealing abilities and antibacterial properties of root canal sealers and intracanal medicaments between appointments have been recognized as important factors for the success of endodontic treatment. Background: Apical periodontitis (AP) is an inflammatory disease around the apex of a tooth root. The microorganisms reach the pulp by dentinal tubules especially when there is an open cavity after a coronal fracture and the pulp is in contact with the septic oral environment. The aim of the study was to evaluate the dynamics of healing by recording periapical index (PAI), after two appointment endodontic procedure with commercial or experimental intracanal medicament. Methods: A total of 40 patients with primary chronic apical periodontitis requiring root canal treatment were assigned randomly into four groups according to the teeth medicated with dehydrated plant extract, calcium hydroxide, calcium hydroxide mixed with chlorhexidine (CHX) gel 2%, Walkhoff paste and obturated on a second visit, 7 days later. Patients were recalled at intervals of 3, 6, and 12 months to evaluate the treated teeth both clinically and radiographically for periapical healing. A 5-score scale PAI was used to evaluate stages of the periapical healing on a periapical radiography using a Kodak Dental imaging software provided by the radio-imagistic center. Results: Radiological evaluation revealed that the experimental intracanal medicament had a cumulative positive healing capacity by reducing the PAI as well as all resorbable pastes used in endodontic conventional therapy. Conclusions: The results suggest that the vegetable dry extract obtained from Epilobium parviflorum Schreb can be used as an inter-appointment medication among with the root canal filling for the positive effect on apical healing quantified by reducing the PAI.

Abstract
Background: Regenerative endodontics aims to restore normal pulp function in necrotic and infected teeth, restoring protective functions, such as innate pulp immunity, pulp repair through mineralization, and pulp sensibility. The aim of this systematic review was to assess the dentin regeneration efficacy of direct pulp capping (DPC) biomaterials. Methods: The literature published between 2005 and 2021 was searched by using PubMed, Web of Science, Science Direct, Google Scholar, and Scopus databases. Clinical controlled trials, randomized controlled trials, and animal studies investigating DPC outcomes or comparing different capping materials after pulp exposure were included in this systematic review. Three independent authors performed the searches, and information was extracted by using a structured data format. Results: A total of forty studies (21 from humans and 19 from animals) were included in this systemic review. Histological examinations showed complete/partial/incomplete dentin bridge/reparative dentin formation during the pulp healing process at different follow-up periods, using different capping materials. Conclusions: Mineral trioxide aggregate (MTA) and Biodentine can induce dentin regeneration when applied over exposed pulp. This systematic review can conclude that MTA and its variants have better efficacy in the DPC procedure for dentin regeneration.

Abstract
Introduction: Direct pulp capping treatment (DPC) maintains pulp vitality by promoting healing or repair in dentistry, which can be attributed to the advent of bioceramic materials. Aim: This examination looked to evaluate the clinical and histological effectuality of Biodentine with Dycal for DPC. Materials and Methodology: In this study, 30 intact human orthodontic teeth undergoing therapeutic extraction were chosen to perform DPC. They were arbitrarily divided into two groups (n = 15) and DPC with Biodentine and Dycal was performed. Composite resin was used as permanent restoration. After a period of 1 and 6 weeks, clinical as well as electric pulp tests were carried out. Asymptomatic patients were re-called after 6 weeks; follow-up radiograph was taken. Electric pulp testing and thermal testing was done to check the pulpal status of the teeth. This was followed by atraumatic extraction, and the teeth were sent for histological examination. SPSS Version 21.0. Armonk, NY: IBM Corp.was used for data analysis. Results: There was no pain and sensitivity in using Biodentine. Whereas, sensitivity and pain was noted when Dycal was used. The dentinal bridge was better with Biodentine when compared with Dycal. Conclusion: In accordance with the obtained results, it was concluded that on clinical and histological evaluation, Biodentine performed better as DPC agent. Subsequently, Biodentine is more dependable for the long-haul protection of dental pulp than Dycal.

Abstract
OBJECTIVE To assess and quantify coronal tooth discolouration by ProRoot MTA, Biodentine and MTA repair HP as pulpotomy agents and to identify colour stability of these materials in presence of blood contamination. METHODS 120 human premolar teeth were used in the study. The teeth were sectioned horizontally 1 mm apical to the cementoenamel junction. A retrograde cavity extending within 2 mm of the incisal edge was prepared. The specimens were randomly distributed as; Control: Group 1, ProRoot MTA: Group 2, Biodentine: Group 3 and MTA repair HP: Group 4. The groups werefurther subdivided on basis of exposure to saline (subgroup A) or blood (subgroup B). The access was sealed with light cured Glass ionomer cemet and the specimens were stored in artificial saliva at 37°C. The Colour change was evaluated with a spectrophotometer at: day 0 (T0), day 1 (T1), day 7 (T7), 1 month (T30), 2 months (T60), and 6 months (T180). The colour measurements were recorded using the Commission Internationale de l'Eclairage L*a*b* value. RESULTS For all groups, there was a sharp increase in L* parameter at T1. At 6 months, Group 1B (Control + blood) showed maximum decrease in luminosity followed by Group 2A (ProRoot + saline) > Group 4B (MTA repair HP + blood) > Group 2B (ProRoot + blood). Group 3A (Biodentine + saline) showed the least amount of decrease in luminosity followed by Group 4A (MTA repair HP + saline) and Group 3B (Biodentine + blood). No significant difference was found in ∆E change between any of the groups from baseline to 180 days (P>0.05). CONCLUSION Relative to L* parameter, it was possible to observe a statistically significant decrease in luminosity in the Group1B (Control + blood) followed by ProRoot MTA (Group 2A and 2B) and MTA repair HP (Group 4A and 4B). Biodentine (Group 3A and 3B) showed least tooth discolouration in terms of L* parameter.

Abstract
Dental pulp vitality is a desideratum for preserving the health and functionality of the tooth. In certain clinical situations that lead to pulp exposure, bioactive agents are used in direct pulp-capping procedures to stimulate the dentin-pulp complex and activate reparative dentinogenesis. Hydraulic calcium-silicate cements, derived from Portland cement, can induce the formation of a new dentin bridge at the interface between the biomaterial and the dental pulp. Odontoblasts are molecularly activated, and, if necessary, undifferentiated stem cells in the dental pulp can differentiate into odontoblasts. An extensive review of literature was conducted on MedLine/PubMed database to evaluate the histological outcomes of direct pulp capping with hydraulic calcium-silicate cements performed on animal models. Overall, irrespective of their physico-chemical properties and the molecular mechanisms involved in pulp healing, the effects of cements on tertiary dentin formation and pulp vitality preservation were positive. Histological examinations showed different degrees of dental pulp inflammatory response and complete/incomplete dentin bridge formation during the pulp healing process at different follow-up periods. Calcium silicate materials have the ability to induce reparative dentinogenesis when applied over exposed pulps, with different behaviors, as related to the animal model used, pulpal inflammatory responses, and quality of dentin bridges.

Abstract
Introduction: Enterococcus faecalis can be found in failed endodontic treatment (FET) even after performing primary endodontic treatment (PET). Calcium hydroxide (Ca(OH)2) cannot fully eliminate this microorganism during PET. Brazilian green propolis (bee glue) was found to be more effective against E. faecalis when compared to Ca(OH)2. A much less studied Malaysian geopropolis (MP) as well as Aloe vera (AV) is antibacterial but is unknown against E. faecalis. Objective: The objective of this study is to determine the antimicrobial effects of MP, AV, and MP + AV in comparison with Ca(OH)2 against E. faecalis, as an intracanal medicament. Materials and Methods: Antimicrobial activity of MP, AV, MP + AV, Ca(OH)2, and dimethyl sulfoxide was tested against E. faecalis using antimicrobial sensitivity testing, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC). The results were analyzed by Kruskal–Wallis test with Mann–Whitney post hoc test and repeated measures analysis of variance with Bonferroni post hoc test (P < 0.05). Results: For agar well-diffusion method, MP + AV gave maximum inhibition zone diameter (mean: 8.11 ± 0.015 mm), MP (mean: 6.21 ± 0.046 mm, Ca(OH)2 (mean: 5.5 ± 0.006), and AV (mean: 5.05 ± 0.012) with P < 0.05. MIC for MP + AV was 2 mg/ml, MP at 8 mg/ml, Ca(OH)2 at 8 mg/ml, and AV at 16 mg/ml. The MBC for MP + AV is at 4 mg/ml, MP at 16 mg/ml, Ca(OH)2 at 16 mg/ml, and AV at 32 mg/ml. Conclusion: The combination of MP and AV consistently showed better antimicrobial activity compared to MP and AV alone against E. faecalis. The findings suggest that MP and AV used in combination may be an ideal intracanal medicament in FET and PET.

Abstract
Objective In this in vitro study, we aimed to analyse the enamel-remineralisation potential of propolis. Materials and methods Twenty enamel blocks (N = 20) were randomly divided into two groups (n = 10). In group 1 (control), enamel blocks were brushed with artificial saliva (AS). In group 2, they were brushed with propolis oil. All the blocks were demineralised by exposing them to 6 wt% citric acid (pH: 2.2) for 5 min. Brushing was performed inside a tooth brushing simulation machine with manual toothbrushes. Each sample received 5,000 linear strokes. Surface microhardness analysis was performed for each sample at three time intervals (pre-demineralisation or baseline, post-demineralisation, and post-remineralisation) to obtain the Vickers hardness numbers (VHNs). Results An enhancement in the microhardness of the enamel samples was observed after brushing with propolis oil when compared with brushing using AS alone. In group 1 (control group), the mean baseline VHN was 583.66. It decreased to 116.23 after demineralisation and increased to 184.02 after remineralisation. The mean baseline VHN of group 2 was 506.91. It decreased to 317.60 after demineralisation and increased to 435.19 after remineralisation. The VHN values of both the groups revealed statistically significant differences (p < 0.05) in inter-group and intra-group comparisons. Conclusion Brushing of enamel blocks with propolis led to a greater enhancement in their microhardness levels when compared with the control group. Future studies are essential to validate the exact mechanism of the beneficial effects of propolis on enamel.

Abstract
Background Direct pulp capping is a vital pulp therapy for a pin-point dental pulp exposure. Applying a pulp capping material leads to the formation of a dentin bridge and protects pulp vitality. The aim of this study was to compare the effects of four dental materials, DyCal®, ProRoot® MTA, Biodentine™, and TheraCal™ LC in vitro. Methods Human dental pulp stem cells (hDPs) were isolated and characterized. Extraction medium was prepared from the different pulp capping materials. The hDP cytotoxicity, proliferation, and migration were examined. The odonto/osteogenic differentiation was determined by alkaline phosphatase, Von Kossa, and alizarin red s staining. Osteogenic marker gene expression was evaluated using real-time polymerase chain reaction. Results ProRoot® MTA and Biodentine™ generated less cytotoxicity than DyCal® and TheraCal™ LC, which were highly toxic. The hDPs proliferated when cultured with the ProRoot® MTA and Biodentine™ extraction media. The ProRoot® MTA and Biodentine™ extraction medium induced greater cell attachment and spreading. Moreover, the hDPs cultured in the ProRoot® MTA or Biodentine™ extraction medium migrated in a similar manner to those in serum-free medium, while a marked reduction in cell migration was observed in the cells cultured in DyCal® and TheraCal™ LC extraction media. Improved mineralization was detected in hDPs maintained in ProRoot® MTA or Biodentine™ extraction medium compared with those in serum-free medium. Conclusion This study demonstrates the favorable in vitro biocompatibility and bioactive properties of ProRoot® MTA and Biodentine™ on hDPs, suggesting their superior regenerative potential compared with DyCal® and TheraCal™.

Abstract
AIM To identify odontogenesis-promoting compounds and examine the molecular mechanism underlying enhanced odontoblast differentiation and tooth formation. METHODOLOGY Five different nymphaeols, nymphaeol B (NB), isonymphaeol B (INB), nymphaeol A (NA), 3'-geranyl-naringenin (GN) and nymphaeol C (NC) were isolated from the fruit of Macaranga tanarius. The cytotoxic effect of nymphaeols on human DPSCs was observed using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The effect of nymphaeols on odontoblast differentiation was analysed with Alizarin Red S staining and odontoblast marker expression was assessed using real-time polymerase chain reaction and Western blot analysis. The molecular mechanism was investigated with Western blot analysis. In order to examine the effect of INB on dentine formation in the developing tooth germ, INB-soaked beads were placed under the tooth bud explants in the collagen gel; thereafter, the tooth bud explant-bead complexes were implanted into the sub-renal capsules for 3 weeks. Tooth root formation was analysed using micro-computed tomography and histological analysis. Data are presented as mean ± standard error (SEM) values of three independent experiments, and results are compared using a two-tailed Student's t-test. The data were considered to have statistical significance when the P-value was less than 0.05. RESULTS Three of the compounds, NB, INB, and GN, did not exert a cytotoxic effect on human DPSCs. However, INB was most effective in promoting the deposition of calcium minerals in vitro (P < 0.001) and induced the expression of odontogenic marker genes (P < 0.05). Moreover, this compound strongly induced the phosphorylation of mitogen-activated protein (MAP) kinases and protein kinase B (AKT) (P < 0.05). The inhibition of p38 MAP, c-Jun N-terminal kinase (JNK), and AKT substantially suppressed the INB-induced odontoblast differentiation (P < 0.001). In addition, isonymphaeol B significantly induced the formation of dentine and elongation of the tooth root in vivo (P < 0.05). CONCLUSIONS Prenylflavonoids, including INB, exerted stimulatory effects on odontoblast differentiation and tooth root and dentine formation via the MAP kinase and AKT signalling pathways. These results suggest that nymphaeols could stimulate the repair processes for dentine defects or injuries.

Abstract
Vital pulp therapies (VPTs) aim to preserve the vitality of the pulp. The European Society of Endodontology have begun a campaign to raise awareness on the efficacy of VPTs following on from the publication of their 2019 position statement, aimed at both specialists and general dental practitioners. This review examines the current evidence surrounding VPTs and provides a rational approach to the management of the exposed pulp with the aid of case studies. Success lies in accurate diagnosis and case selection, along with well-executed treatment and appropriate follow-up protocols. The introduction of calcium silicate cements has made these treatments more predictable.

Abstract
This study compared the biological effect of Hesperidin, Mineral Trioxide Aggregate (MTA)-Angelus and calcium hydroxide for direct pulp capping. A total of 126 dogs, teeth were divided according to the post-treatment evaluation period into three groups (42 teeth each), group I: 2 weeks, group II: 4 weeks and group III: 8 weeks. Each group was further subdivided according to the pulp capping material into three subgroups (14 teeth each), subgroup A (Hesperidin), subgroup B (MTA-Angelus) and subgroup C (Dycal). Both inflammatory response and dentine bridge formation were assessed by histopathology. All data were statistically analysed. Resolution of the inflammation was recorded by the time with a significant difference between subgroups within the same group (P<.05). Hesperidin, MTA-Angelus and Dycal showed either mild or moderate inflammation at 2 weeks with significant differences between subgroups (P < .05). At 4 and 8 weeks, there were no significant differences between subgroups (P > .05). Absence of complete or partial calcified bridge with no odontoblastic layer was reported in all subgroups at 2 weeks while at 4 weeks, the majority of samples in Hesperidin and MTA subgroups showed amorphous calcified deposit. At 8 weeks, there was no significant difference (P > .05) between subgroups except that 78.5% and 92.9% of Hesperidin and MTA-Angelus samples, respectively, showed moderate dentine bridge. Also, 78.5% of Hesperidin and Dycal samples revealed moderately thick dentine bridge while 78.7% of MTA-Angelus showed a thin dentine bridge with a significant difference between them (P < .05). In conclusion, Hesperidin is a promising pulp capping material inducing mild inflammation and good dentine bridge formation.

Abstract
Objective
To analyze the expression of nuclear factor kappa B (NF-kB) and collagen type 1 on dental pulp after a treated combination of calcium hydroxide and propolis.
Materials and Methods
The first maxillary molars of 30 rats were mechanically perforated. Teeth were divided into three groups of 10 for two separate extraction time frames, giving a total of 60 rats. The control groups were treated with Cention, the second treatment groups were treated with calcium hydroxide, and the third treatment groups were treated with a combination of calcium hydroxide and propolis. Final restoration was done with Cention. The teeth were extracted on days 7 and 14, and the expression of NF-kB and collagen type I was analyzed using immunohistochemistry.
Results
There is lowest NF-kB expression and highest collagen type 1 expression on dental pulp after treated with a combination of calcium hydroxide and propolis on days 7 and 14 (
p
< 0.05).
Conclusion
The combination of calcium hydroxide and propolis inhibits pulp inflammation and stimulates regeneration through decreasing the NF-kB expression and increasing collagen type 1.

Abstract
The response of the dentin-pulp complex in rat teeth was investigated after direct capping with biodentine with or without bone marrow-derived stem cells (BMDSCs). Following mechanical exposure, pulps were randomly capped with one of the followings materials: calcium hydroxide, biodentine or 1 × 105 BMDSCs mL-1 + biodentine. Histological examination was performed by light microscopy after 1, 3 and 5 weeks. Inflammatory reaction, necrotic tissue formation and calcific bridge formation were scored. Analysis showed that compared with the effects of calcium hydroxide or biodentine, BMDSCs + biodentine substantially reduced inflammatory reaction and necrotic tissue while promoting calcified tissue formation. Therefore, the combination of biodentine and BMDSCs could potentially stimulate pulp tissue regeneration after direct pulp capping.

Abstract
Odontoblast cells generated from human dental pulp stem/progenitor cells (hDPSCs) secrete reparative dentin in responds to an injury. Endogenous Wnt signaling is also activated during this process, and these Wnt-activated cells are responsible for the following repair response. R-spondin 2 (Rspo2) is a potent stem cell growth factor, which strongly potentiates Wnt/β-catenin signaling and plays a vital role in cell differentiation and regeneration. However, the role of Rspo2 during odontoblast differentiation in hDPSCs has not yet been completely understood. This study investigated the effects of Rspo2 on hDPSCs to provide therapeutic insight into dentin regeneration and reparative dentin formation. HDPSCs were extracted from human molars or premolars. Immunofluorescence staining and flow cytometric analysis were used to detect the mesenchymal stem cell markers in hDPSCs. EdU assay and Cell Counting Kit-8 (CCK-8) were performed to explore cell proliferation. The odontogenic differentiation levels were determined by measuring the mRNA and protein expression of DSPP, DMP-1, ALP, and BSP. Immunofluorescence staining was performed to detect the localization of β-catenin. The biological effects of Rspo2 on hDPSCs was investigated using the Lentivirus-based Rspo2 shRNA and recombined human Rspo2 (rhRspo2). Recombined human DKK-1 (rhDKK-1) and recombined human Wnt3a (rhWnt3a) were used for further investigation. The cells generated from human dental pulp expressed mesenchymal stem cell markers Vimentin, Stro-1, Nestin, C-kit, CD90, and CD73, while were negative for CD3, CD31, and CD34. The mRNA expression levels of the odontogenic-related genes DSPP, DMP-1, ALP, and BSP were upregulated in the rhRspo2 treated cells. Silencing Rspo2 suppressed the proliferation and differentiation of the hDPSCs. Blockade of Wnt signaling with DKK-1 inhibited Rspo2-induced activation of Wnt/β-catenin signaling and cell differentiation. The combined use of rhWnt3a and rhRspo2 created a synergistic effect to improve the activation of Wnt/β-catenin signaling. Rspo2 promoted the proliferation and odontogenic differentiation of hDPSCs by regulating the Wnt/β-catenin signaling pathway.

Abstract
This study aims to achieve the principles of tissue engineering using biopolymers to be applied in the field of vital endodontic treatment to stimulate stem cells and engineering and regeneration of dentin tissue. the polymer blend was loaded with the steroidal anti-inflammatory drug, dexamethasone, and the porous drug-loaded bio-sponge was produced by lyophilization. Bio-sponge, as a direct pulp capping agent, was histologically studied compared to calcium hydroxide Ca(OH)2 in an animal experiment. The results indicated the effectiveness of the bio-sponge as a direct pulp capping agent where the dentin bridge was formed faster than Ca(OH)2 treated samples. There was no inflammatory response in the pulp tissue throughout the follow-up period. The porous bio-sponge loaded with dexamethasone with a neutral pH resulted in enhancement of the odontoblast differentiation from stem cells, resulting in the formation of a renewed dentin bridge without the slightest inflammatory response in the pulp.

Abstract
Background. In the era of biology-driven endodontics, vital pulp therapies are regaining popularity as a valid clinical option to postpone root-canal treatment. In this sense, many different materials are available in the market for pulp-capping purposes. Objectives. The main aim of this systematic review and meta-analysis was to examine literature regarding cytotoxicity and bioactivity of pulp-capping agents by exposure of human dental pulp cells of primary origin to these materials. A secondary objective was to evaluate the inflammatory reaction and reparative dentin-bridge formation induced by the different pulp-capping agents on human pulp tissue. Data sources. A literature search strategy was carried out on PubMed, EMBASE and the Web of Science databases. The last search was done on 1 May 2020. No filters or language restrictions were initially applied. Two researchers independently selected the studies and extracted the data. Study selection included eligibility criteria, participants and interventions, study appraisal and synthesis methods. In vitro studies were included when human dental pulp cells of primary origin were (in) directly exposed to pulp-capping agents. Parallel or split-mouth randomized or controlled clinical trials (RCT or CCT) were selected to investigate the effects of different pulp-capping agents on the inflammation and reparative bridge-formation capacity of human pulp tissue. Data were synthesized via odds ratios (95% confidence interval) with fixed or random effects models, depending on the homogeneity of the studies. The relative risks (95% confidence interval) were presented for the sake of interpretation. Results. In total, 26 in vitro and 30 in vivo studies were included in the systematic review and meta-analysis, respectively. The qualitative analysis of in vitro data suggested that resin-free hydraulic calcium-silicate cements promote cell viability and bioactivity towards human dental pulp cells better than resin-based calcium-silicate cements, glass ionomers and calcium-hydroxide cements. The meta-analysis of the in vivo studies indicated that calcium-hydroxide powder/saline promotes reparative bridge formation better than the popular commercial resin-free calcium-silicate cement Pro-Root MTA (Dentsply-Sirona), although the difference was borderline non-significant (p = 0.06), and better than calcium-hydroxide cements (p < 0.0001). Moreover, resin-free pulp-capping agents fostered the formation of a complete reparative bridge better than resin-based materials (p < 0.001). On the other hand, no difference was found among the different materials tested regarding the inflammatory effect provoked at human pulp tissue. Conclusions. Calcium-hydroxide (CH) powder and Pro-Root MTA (Dentsply-Sirona) have shown excellent biocompatibility in vitro and in vivo when tested on human cells and teeth. Their use after many years of research and clinical experience seems safe and proven for vital pulp therapy in healthy individuals, given that an aseptic environment (rubber dam isolation) is provided. Although in vitro evidence suggests that most modern hydraulic calcium-silicate cements promote bioactivity when exposed to human dental pulp cells, care should be taken when these new materials are clinically applied in patients, as small changes in their composition might have big consequences on their clinical efficacy. Key findings (clinical significance). Pure calcium-hydroxide powder/saline and the commercial resin-free hydraulic calcium-silicate cement Pro-Root MTA (Dentsply-Sirona) are the best options to provide a complete reparative bridge upon vital pulp therapy.

Abstract
Background: Caries in the dental pulp result in inflammation and damage to the pulp tissue. During inflammation of the pulp, various inflammatory mediators and growth factors are released, including IL-8, IL-10, TLR-2, VEGF and TGF-β through the NF-kB pathway. In the present study, therapy for pulpal caries was performed through pulp capping by giving a combination of propolis and calcium hydroxide (Ca(OH)2). This treatment was expected to stimulate the formation of reparative dentin as an anti-inflammatory material to prevent pulp tissue damage. Methods: 28 Wistar rats were divided into four groups and treated with Ca(OH)2 with or without the addition of propolis for either 7 or 14 days. Immunohistochemical examination was used to determine the expression of IL-8, IL-10, TLR-2, VEGF, TGF-β in the four treatment groups. Results: The group treated with a combination of propolis and Ca(OH)2 for 7 days showed that the expression of IL-10, IL-8, TLR-2, VEGF, TGF-β increased significantly compared to the treatment group treated with only Ca(OH)2. The expression of IL-10, TLR-2, TGF-β, VEGF increased in the treatment group treated with propolis and Ca(OH)2 for 14 days, while the expression of IL-8 in the decreased significantly. Conclusions: Administration of a combination of propolis and Ca(OH)2 has efficacy in the pulp capping treatment process because it has anti-bacterial and immunomodulatory properties. The results show that it is able to stimulate the process of pulp tissue repair through increased expression of IL-10, TGF-β, VEGF, TLR -2 and decreased expression of IL-8.

Abstract
BACKGROUND Pulpectomy is a routine practice in children with pulpal and periapical infections, the success of which depends on the elimination of bacteria from the root canals. Propolis, a natural product with proven antibacterial and anti-inflammatory properties when mixed with zinc oxide powder as root canal filling material, it could provide good success in endodontic therapy of primary teeth. AIM The aim was to evaluate and compare the clinical effectiveness of zinc oxide-propolis mixture with zinc oxide eugenol (ZOE) as root canal filling material in nonvital primary molars. SETTINGS AND DESIGN This was a 2-arm, parallel group randomized controlled trial with blinded outcome assessment. MATERIALS AND METHODS Forty primary molars from children aged 4-8 years requiring pulpectomy treatment were randomly allocated into two groups according to the obturating material used: zinc oxide-propolis mixture (test group) and ZOE (control group). All the pulpectomy treated teeth were finally restored with stainless steel crowns, and the children were recalled at 6, 12, and 24 months for postoperative clinical and radiographic evaluation. STATISTICAL ANALYSIS Chi-square test was used to analyze the data. RESULTS The overall success rate of pulpectomy with zinc oxide-propolis mixture and ZOE was found to be 95% and 70%, respectively, and the difference was statistically significant (P = 0.037). Zinc oxide-propolis mixture has shown a success rate of 100% at 6 months and 95% at 12 and 24 months follow-up, whereas ZOE has shown 80% success rate at 6 and 12 months, and it declined to 70% at 24-month follow-up. CONCLUSION Zinc oxide-propolis mixture demonstrated good clinical and radiographic success at the end of 24 months, and hence, it can be considered as an alternate root canal filling material in the primary teeth.

Abstract
Propolis is a potent anti-microbial and natural anti-inflammatory by-product obtained from the beehive. Studies have demonstrated the superior biocompatibility and anti-microbial properties of propolis as compared to calcium hydroxide. However, its effect on postoperative endodontic pain is unknown. Therefore, this study aimed to investigate the impact of Chinese propolis paste as an intracanal medicament on postoperative endodontic pain intensities compared with calcium hydroxide (control) at different time intervals in necrotic teeth with periapical radiolucency. Eighty patients with single-rooted necrotic teeth with visible periapical radiolucency were recruited and randomly allocated to either the calcium hydroxide or propolis groups. After chemo-mechanical preparation and intracanal medicament insertion, patients were given the VAS (visual analogue scale) to record pain scores. Inter-group data were compared and analyzed using two-way repeated measure ANOVA (Bonferroni test). A p-value of < 0.025 was considered significant. In total, >78% of the patients experienced no or only mild post-operative pain in both the groups at all time intervals, without any significant difference in pain scores between the two groups (p > 0.025). An overall flare-up rate of 14.8% was found. The results suggest that either of these medicaments can be used as an inter-appointment medication for the prevention of postoperative pain in necrotic cases.

Abstract
The aim of this study is to investigate combined effects of mineral trioxide aggregate (MTA) and propolis on odontoblastic differentiation of human dental pulp stem cells (DPSCs) and to find a signaling pathway involved. Combination of MTA and propolis significantly up-regulated the expression of DSPP and DMP1, and facilitated a mineral nodule formation (p < 0.05). Treatments with MTA, propolis or combined increased the phosphorylation of extracellular signal-regulated kinases (ERK), one of mitogen-activated protein kinases signaling cascades during odontogenic differentiation of DPSCs (p < 0.05), and U0126, an inhibitor of ERK, decreased calcium deposits (p < 0.05). Combination of MTA and propolis promotes odontogenic differentiation and mineralization of DPSCs through ERK pathway.

Abstract
INTRODUCTION Dental pulp stem cells (DPSCs) are multipotent progenitors for biotechnological practices, but the influences of existing restorations on their viability and differentiation are not well-known. This study was aimed to investigate in vivo and in vitro responses of DPSCs to restorative materials. METHODS Class I cavities were prepared on molars scheduled to be extracted and then restored with a resin-based composite (RBC), a glass ionomer cement, or zinc oxide eugenol. Intact teeth were used as controls. Twelve molars in each group were extracted on day 7 or day 30 after restorations to assess the early or intermediate pulp responses and were then cut in half. One half was processed for histopathological analysis, and the other was used to isolate DPSCs for a colony-forming unit assay and real-time polymerase chain reaction for NANOG, OCT4, and CD44 expression. RESULTS All restored teeth showed pulp damage at various levels, whereas mild to moderate inflammation persisted in the RBC group until day 30. The existence of DPSCs in the pulp cores of all groups was revealed based on CD44 immunoreactivity. Glass ionomer cement and zinc oxide eugenol did not affect the relative percentages of DPSCs in either early or intermediate stages, whereas RBCs reduced the percentage. The colony-forming units in all restoration groups were comparable with those in the control. Nevertheless, the restorations significantly enhanced OCT4 expression, especially in RBC/day 30. CONCLUSIONS Dental restorations cause mild pulp damage but do not affect DPSC viability. RBC decreases DPSC densities but might increase the stemness of surviving DPSCs through an inflammation-stimulation process.

Abstract
This study examined and compared wound healing between Thai propolis product and calcium hydroxide paste as pulp-capping agents after partial pulpotomy in New Zealand white rabbits. Forty incisor teeth from 10 rabbits were treated. Thirty-six teeth received class V cavity preparations with partial pulpotomy and application of either propolis or calcium hydroxide paste. Similar cavity preparations were performed in 2 teeth without any capping material as a positive control, whereas 2 teeth without the cavity preparation served as a negative control. Histological evaluation showed that both groups had dentin bridge formation. Dentinal tubules in the dentin bridge were more orderly arranged in the Thai propolis group than in the calcium hydroxide group. Wound healing and the median number of hyperemic blood vessels were not statistically significant different between the 2 groups. Thai propolis product may be used as a pulp-capping agent.

Abstract
Background Carbonate apatite (CO3Ap) and silica-calcium phosphate composite (SCPC) are bone substitutes with good prospect for dental application. SCPC creates a hydroxyapatite surface layer and stimulate bone cell function while, CO3Ap induce apatite crystal formation with good adaptation providing good seal between cement and the bone. Together, these materials will add favorable properties as a pulp capping material to stimulate mineral barrier and maintain pulp vitality. The aim of this study is to investigate modification of CO3Ap cement combined with SCPC, later term as CO3Ap-SCPC cement (CAS) in means of its chemical (Calcium release) and physical properties (setting time, DTS and pH value). Methods The study consist of three groups; group 1 (100% calcium hydroxide, group 2 CO3Ap (60% DCPA: 40% vaterite, and group 3 CAS (60% DCPA: 20% vaterite: 20% SCPC. Distilled water was employed as a solution for group 1, and 0.2 mol/L Na3PO4 used for group 2 and group 3. Samples were evaluated with respect to important properties for pulp capping application such as pH, setting time, mechanical strength and calcium release evaluation. Results The fastest setting time was in CO3Ap cement group without SCPC, while the addition of 20% SCPC slightly increase the pH value but did not improved the cement mechanical strength, however, the mechanical strength of both CO3Ap groups were significantly higher than calcium hydroxide. All three groups released calcium ions and had alkaline pH. Highest pH level, as well as calcium released level, was in the control group. Conclusion The CAS cement had good mechanical and acceptable chemical properties for pulp capping application compared to calcium hydroxide as a gold standard. However, improvements and in vivo studies are to be carried out with the further development of this material.

Abstract
Aim and objectives Aim of the study was to evaluate the success of magnetic nanoparticles (MNPs) as pulpotomy medicament by clinical, radiologic, and histological assessment in primary molars. Materials and methods The sample included 30 primary molars from 25 children aged between 3 and 9 years requiring pulpotomy treatment. Pulpotomy was carried out with MNPs. The teeth were evaluated after a period of 3, 6, and 12 months clinically and with the aid of radiographs. After 1 year, 10 teeth were extracted for histological evaluation under field emission scanning electron microscope (FE-SEM; ZEISS, Model No. Supra 55vp). Results Of the samples, 98% showed clinical success rate with absence of pain, swelling, mobility, and abscess formation. After 3 months, 98% radiological success with absence of periodontal ligament widening, root resorption, and inter-radicular radiolucency was noted. Histological examination carried out under FE-SEM revealed a zone of odontoblastic proliferation at the interface between MNPs and odontoblastic layer of pulp and viable pulpal cells from the canal orifice till apical foramen. Conclusion Magnetic nanoparticles can be recommended as an effective pulpotomy medicament with hard tissue barrier formation and preservation of vitality of remaining radicular pulp.

Abstract
A modified mineral-trioxide-aggregate (mMTA) with rapid setting capacity was newly synthesized by spray-pyrolysis following a sol-gel reaction. Its faster setting capacity and initially higher compressive strength compared with Portland cement (PC) were evaluated. The precursor solution of the mMTA was prepared through condensation following hydrolysis among Ca(NO3 )2 ·4H2 O, Si(OC2 H5 )4 , and Al(NO3 )3 ·9H2 O under nitric acid. The mMTA powder was then synthesized by spray-pyrolysis at 1500°C. The particle shape was spherical with an average particle size of 0.8 ± 0.3 μm, while PC particles were irregular and 3.9 ± 3.0 μm in size. The mMTA consisted of mostly Ca3 SiO5 , Ca3 Al2 O6 , and partial Ca2 SiO4 phases, while the PC comprised mainly Ca3 SiO5 , Ca2 SiO4 , and partial Ca3 Al2 O6 phases. The final setting times of mMTA and PC measured under 95% relative humidity were about 11 min and 3 h, respectively. The early stage of setting in mMTA was dominated by the rapid formation of hexagonal-plate-like Ca3 Al2 O6 ·6H2 O crystals, while that in PC was dominated by needle-like calcium-silicate-hydrate gels and columnar-shaped Ca(OH)2 crystals. The late stage of setting in mMTA was dominated by calcium-silicate-hydrate gels and Ca(OH)2 crystals, while that in PC was dominated by Ca3 Al2 O6 ·6H2 O crystals. The compressive strengths of mMTA and PC after 30 min of setting were 4.5 and 0.2 MPa, respectively. The results suggest that mMTA has potential to be used as a filling material for accidental pulp-exposure or pulpal floor perforation cases that require rapid setting capacity and initial good strength. © 2018 Wiley Periodicals, Inc.

Abstract
INTRODUCTION Few studies have reported direct pulp capping in inflamed pulp conditions. The purpose of this study was to investigate the in vitro and in vivo responses of dental pulp during direct pulp capping using various pulp capping materials in inflamed conditions. METHODS Human dental pulp cells were treated with lipopolysaccharide (LPS) and cultured with Dycal (Dentsply Caulk, Milford, DE), ProRoot MTA (Dentsply Maillefer, Ballaigues, Switzerland), and Endocem MTA (Maruchi, Wonju, South Korea). The expressions of interleukin (IL)-1β, IL-6, dentin matrix protein 1, and dentin sialophosphoprotein were analyzed through real-time polymerase chain reaction. The maxillary molars of Sprague-Dawley rats were exposed for 2 days. The exposed pulps were capped with Dycal, ProRoot MTA, and Endocem MTA and sealed with resin-modified glass ionomer followed by histologic and immunohistochemical analyses. RESULTS The expression of IL-1β and IL-6 was increased with LPS and decreased by Dycal, ProRoot MTA, and Endocem MTA. Dentin matrix protein 1 and dentin sialophosphoprotein levels were decreased with LPS and increased after treatment with pulp capping materials.In the in vivo study, inflammation associated with Dycal was higher than that associated with ProRoot MTA and Endocem MTA at week 1, without any significant difference between the 2. At 4 weeks, inflammation was decreased, and mineralization was increased compared with week 1 in all 3 of the materials. At week 1, IL-6 immunoreactivity was strongly expressed. Dycal exhibited stronger immunoreactivity than ProRoot MTA and Endocem MTA. However, the immunoreactivity was decreased in all groups at week 4. CONCLUSIONS Successful direct pulp capping requires more effective pulp capping materials for the treatment of inflamed pulps.

Abstract
BACKGROUND The authors of this systematic review aimed to compare the effects of pulp-capping materials on hard-tissue barrier formation using histologic assessments. TYPE OF STUDIES REVIEWED The authors included randomized controlled trials and controlled clinical trials in humans, with vital therapies performed on healthy permanent teeth undergoing experimental mechanical pulp exposures. They searched electronically in the PubMed, Cochrane, Embase, and Summon databases and carried out a manual search. Twenty-seven full-text articles were eligible for inclusion in the systematic review. After data extraction, the authors performed 2 sets of meta-analyses with odds ratios (OR) and their 95% confidence intervals (CI) on 22 studies. Ten studies compared mineral trioxide aggregate (MTA) with calcium hydroxide (CH), and 12 compared bonding agents with CH. The authors assessed bias by means of Cochrane Collaboration's tool for assessing risk, funnel plots, and Harbord test. RESULTS The use of MTA was associated with a higher rate of hard-tissue barrier formation than CH. The OR comparing the 2 groups was 2.45 (95% CI, 1.39 to 4.29; P = .002). Use of bonding agents was associated with a lower rate of hard-tissue barrier formation than CH. The OR comparing the 2 groups was 0.02 (95% CI, 0.01 to 0.05; P < .001). CONCLUSIONS AND PRACTICAL IMPLICATIONS The results suggest that MTA and CH have positive effects on hard-tissue barrier formation. On the basis of the evidence, the authors conclude that MTA has better effects than CH regarding dental pulp protection in the capping of mechanical pulp exposures. Conversely, bonding agents are inferior to CH.

Abstract
BACKGROUND Propolis is a natural substance produced by bees and is known to have antimicrobial activity. Our aim was to evaluate the antimicrobial effect of micellar nanocomposites loaded with an ethyl acetate extract of Brazilian red propolis as a cavity cleaning agent and its influence on the color and microtensile bond strength (μTBS) of the dentin/resin interface. METHODS An ultra-performance liquid chromatography coupled with a diode array detector (UPLC-DAD) assay was used to determine the flavonoids and isoflavones present in an ethyl acetate extract of Brazilian red propolis (EARP) and micellar nanocomposites loaded with EARP (MNRP). The antimicrobial activity of EARP and MNRP was tested against Streptococcus mutans, Lactobacillus acidophilus, and Candida albicans. One of the following experimental treatments was applied to etched dentin (phosphoric acid, 15 s): 5 μL of MNRP (RP3, 0.3%; RP6, 0.6%; or RP1, 1.0% w/v), placebo, and 2% chlorhexidine digluconate. Single Bond adhesive (3 M/ESPE) was applied and a 4-mm-thick resin crown (Z350XT, 3 M/ESPE) was built up. After 24 h, the teeth were sectioned into sticks for the μTBS test and scanning electron microscopy. Spectrophotometry according to the CIE L*a*b* chromatic space was used to evaluate the color. Data were analyzed using one-way ANOVA and the Tukey test or Kruskal-Wallis test and the same test for pairwise comparisons between the means (P < 0.05). RESULTS The UPLC-DAD assay identified the flavonoids liquiritigenin, pinobanksin, pinocembrin, and isoliquiritigenin and the isoflavonoids daidzein, formononetin, and biochanin A in the EARP and micellar nanocomposites. EARP and MNRP presented antimicrobial activity against the cariogenic bacteria Streptococcus mutans and Lactobacillus acidophilus, and for Candida albicans. ΔE values varied from 2.31 to 3.67 (P = 0.457). The mean μTBS for RP1 was significantly lower than for the other groups (P < 0.001). Dentin treated with RP1 showed the shortest resin tags followed by RP6 and RP3. CONCLUSIONS The EARP and (MNRP) showed antimicrobial activity for the main agents causing dental caries (Streptococcus mutans and Lactobacillus acidophilus) and for Candida albicans. MNRP at concentrations of 0.3 and 0.6% used as a cavity cleaner do not compromise the aesthetics or μTBS of the dentin/resin interface.

Abstract
In this study we designed a composite biomaterial based on a high viscosity soft propolis extract (70% propolis) and shell clam, with antiseptic and osteoinductive qualities, that can be used in dentistry, orthopedics and other areas where hard tissue regeneration is needed. We assessed it in interaction with stabilized human cells isolated from dental papilla of wisdom teeth (D1MSCs). We performed detailed characterization of the obtained material by Scanning Electronic Microscopy (SEM), X-Ray Diffraction (XRD), Energy Dispersive X-Ray Spectroscopy (EDX), Fourier Transform Infrared Spectroscopy (FTIR) techniques. SEM investigation revealed the roughness and porosity of the shell, which acted like a scaffold, as it allowed cells to penetrate the pores, proliferate on the surface, spread and grow in the depressions provided by the substrate. in vitro cell viability, proliferation and differentiation assays showed that the newly obtain biomaterial presented low toxicity on D1MSCs and determined the development of numerous osteogenic nodules that were in a higher number even than in the specific induction medium. Our results demonstrated that the shell-propolis based biomaterial promoted and sustained human stem cells attachment, proliferation and differentiation, presenting an important osteoinductive effect essential for mineralized tissue reparation process.

Abstract
BACKGROUND/AIM Avulsed teeth should be immediately replanted into the socket or otherwise kept in a physiologic storage medium to maintain periodontal ligament cell viability. A previous study has demonstrated that Thai propolis extract can maintain viability of human periodontal ligament cells. However, root resorption by osteoclasts often occurs when the avulsed teeth are replanted. The aim of this study was to determine the inhibitory effect of Thai propolis extract on human osteoclastogenesis in vitro. MATERIALS AND METHODS Human peripheral blood mononuclear cells were isolated for osteoclast precursors and cultured in the presence or absence of various non-toxic concentrations of propolis extract, as determined by the alamarBlue® assay, during in vitro induction of osteoclastogenesis. Osteoclast formation was examined by tartrate-resistant acid phosphatase staining, actin ring formation, and real-time polymerase chain reaction. The resorption pit assay was performed to determine osteoclast function. RESULTS Non-toxic concentrations of propolis extract suppressed osteoclast formation by significantly decreasing the percentages of tartrate-resistant acid phosphatase-positive multinuclear cells and the ratios of cells with F-actin ring formation (P < .01) in a dose-dependent fashion. Expression of several osteoclast-specific genes was significantly downregulated by propolis in a dose-dependent manner (P < .05). The percentages of resorption areas on dentin slices were significantly decreased by propolis (P < .05). CONCLUSIONS Thai propolis can inhibit human osteoclast formation and function, which may be beneficial for prevention of root resorption following replantation of avulsed teeth.
