Expert consensus on irrigation and intracanal medication in root canal therapy. Int J Oral Sci 2024; 16:23. [PMID: 38429299 PMCID: PMC10907616 DOI: 10.1038/s41368-024-00280-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 12/22/2023] [Accepted: 01/03/2024] [Indexed: 03/03/2024] Open
Abstract
Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment. However, irrigant selection or irrigation procedures are far from clear. The vapor lock effect in the apical region has yet to be solved, impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes. Additionally, ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified. Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes. Indeed, clinicians have been aware of these concerns for years. Based on the current evidence of studies, this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions. The evolution of different kinetic irrigation methods, their effects, limitations, the paradigm shift, current indications, and effective operational procedures regarding intracanal medication are also discussed. This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication, thus facilitating a better understanding of infection control, standardizing clinical practice, and ultimately improving the success of endodontic therapy.

Abstract
Aim: The aim of this study was to investigate the diffusion of triamcinolone and demeclocycline from an endodontic paste when used unmodified, versus when combined in equal parts with a calcium hydroxide paste, in terms of diffusion through the dentinal tubules versus through the apical foramen. Methodology: Medicaments were placed in endodontically prepared roots that were kept in vials of Milli-Q water. The five experimental groups in the study were (1) control – no medicament, (2) medicament containing triamcinolone and demeclocycline (T&D) and occluded apex, (3) T&D paste and patent apex, (4) T&D + calcium hydroxide (Ca(OH)2) occluded apex, and (5) T&D + Ca(OH)2 and patent apex. The triamcinolone and demeclocycline concentrations were measured with solid-phase extraction and ultra-high performance liquid chromatography–mass spectrometry, after 1, 3, 8, and 24 h, and after 1 week. Results: Most of the triamcinolone and demeclocycline diffused through the apical foramen, with sparse diffusion through the dentinal tubules. The T&D paste mixed with Ca(OH)2 in equal amounts showed greater than the expected 50% reduction in the diffusion of triamcinolone and demeclocycline from mass dilution alone (89% and 80%, respectively). Conclusions: These results stress the importance of maintaining apical patency, for allowing diffusion of active components of the drugs to target tissues in the periapical environment.

Abstract
Pain associated with infections of the tooth pulp and periapical tissues is intense and often the most common reason for patients seeking emergency dental care. Effective management of acute dental pain requires a deep understanding of pain mechanisms, which enables accurate diagnosis and definitive treatment. While drugs are only used as an adjunct to definitive dental treatment, a thorough understanding of their mechanism of action and effectiveness enables clinicians to effectively control intra-operative and post-operative pain and prevent persistent pain. This review describes how pain is detected, processed, and perceived. It also provides information on evidence-based strategies on the use of different classes of drugs to effectively manage endodontic pain.

The Safety and Efficacy of Pre- and Post-Medication for Postoperative Endo- dontic Pain: A Systematic Review and Network Meta-analysis. Open Dent J 2020. [DOI: 10.2174/1874210602014010563] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022] Open
Abstract
Background:
Postoperative Endodontic Pain is a major concern for dentists and their patients, with pain having been reported to occur in 25%–40% of patients treated. Therefore, the aim of this systematic review and Network Meta-analysis (NMA) was to identify the safety and efficacy of pre- and post-medication for reducing postoperative endodontic pain.
Methods:
A literature search was performed in the SCOPUS, MEDLINE, and ScienceDirect, and Cochrane Central databases until December 2019 with no language restriction. Randomized controlled trials evaluating the efficacy of pre- or post-medications compared with other agents, placebo, or no treatment in adult patients who underwent endodontic surgery for postoperative pain were included. The mean difference of postoperative pain was measured using the Standardized Mean Difference (SMD) with its 95% confidence interval (95% CI).
Results:
This Systematic Review included 62 Articles. Of them, 50 studies were included in the NMA. Among all medications, corticosteroids were ranked as the best treatment for the reduction of postoperative pain at 6 and 12 hours with a significant reduction in postoperative pain scores [SMD= -1.18, 95% CI (-1.51: -0.85)] and [SMD= -1.39, 95% CI (-1.77: -1.02)], respectively. Cyclooxygenase-2 (COX-2) inhibitors were ranked as the best treatment for the reduction of postoperative pain at 8 and 24 hours with a significant reduction in postoperative pain scores [SMD= -2.86, 95% CI (-6.05: -1.66)] and [SMD= -1.27, 95% CI (-2.10: -0.43)], respectively. Non-steroidal anti-inflammatory drugs (NSAIDs) significantly reduced the postoperative pain scores in all durations. For postoperative pain at 6 hours, Indomethacin, Novafen, Naproxen, Prednisolone, Ketorolac, Betamethasone, Dexamethasone, Deflazacort, Rofecoxib, Piroxicam, and Ibuprofen significantly reduced the pain score when compared with a placebo. All of these drugs demonstrated a significant reduction at 12 hours except Ketorolac.
Conclusion:
The current evidence suggests that pre- and post-medication can reduce postoperative pain after nonsurgical root canal treatment. Corticosteroids and COX-2 inhibitors showed significant control of the pain up to 12 hours after administration. However, NSAIDs demonstrated a high efficacy from administration and until two days after treatment. Indomethacin, Novafen, prednisolone, and Naproxen were ranked first in most analyzed durations.

Abstract
OBJECTIVE This study aimed to investigate the anti-inflammatory effect of betamethasone on LPS-stimulated human dental pulp stem cells (DPSCs) and its associated mechanism. The osteo-/odontogenic differentiation and osteoclast effect of betamethasone on DPSCs and stem cells from human exfoliated deciduous teeth (SHED) were evaluated. DESIGN The proliferative effect of betamethasone on DPSCs was analyzed using a cholecystokinin octapeptide assay. The anti-inflammatory effect of betamethasone was investigated using quantitative polymerase chain reaction (qPCR) and ELISA. The anti-inflammatory mechanism was explored using qPCR, Western blot, and immunofluorescence staining. The osteo-/odontogenic differentiation and osteoclast effect of betamethasone on DPSCs and SHED were detected by qPCR. RESULTS 1 μg L-1 betamethasone was found to have the strongest effect on DPSCs proliferation. The expression of pro-inflammatory cytokines and mediators, as well as prostaglandin E2 (PGE2) were significantly decreased following treatment with betamethasone in LPS- stimulated DPSCs. They were also decreased in response to an NF-κB inhibitor, Bay 11-7082. Betamethasone and Bay 11-7082 significantly inhibited the expression of p-p65 and promoted the nuclear exclusion of p65. Gene expression associated with osteo-/odontogenic differentiation was significantly up-regulated in betamethasone and osteogenic media (OM) treated groups. The ratio of the receptor activator of nuclear factor kappa B ligand (RANKL) and osteoprotegerin (OPG) at the mRNA level was suppressed in DPSCs and elevated in SHED. CONCLUSIONS Betamethasone has an anti-inflammatory effect on LPS- stimulated DPSCs through a blockade of NF-κB activation and exhibits an osteo-/odonto-inductive effect on DPSCs and SHED. Although betamethasone displays an osteoclast effect on SHED.

Abstract
This systematic review aimed to analyze the efficacy of corticosteroid premedication compared to placebo or no treatment to reduce postoperative pain in endodontic patients. Randomized controlled trials (RCTs) assessing corticosteroids via oral, intramuscular, subperiosteal, intraligamentary or intracanal route compared to passive or active placebo, or no treatment were included. Four databases were searched: PubMed, Web of Science, Cochrane Library and Embase up to 2/21/2018. Risk of bias was assessed with Cochrane Risk of bias tool. Fourteen RCTs with 1,462 generally healthy adults in need of endodontic treatment were included. 50% of the studies were at unclear risk and 50% at high risk of bias. Meta-analysis showed Visual Analog Scale (VAS) pain at 4-6 hours after Inferior Alveolar Nerve Block (IANB) was significantly lower by 21 points (0-100 scale) in the corticosteroid group compared to the control group (95% CI -35 to -7; P = 0.003), however this difference was not statistically significant after 24 hours (P = 0.116). The route of administration was oral and intraligament injection. Patients who received corticosteroids prior to IANB were 70.7% more likely to have none or mild pain 4-8 hours after treatment (P = 0.001) and 13.5% more likely 24 hours after IANB (P = 0.013) than patients in the control group. In conclusion, corticosteroid administration (oral or intraligamental) may clinically reduce the level of postoperative pain at 4-8 hours after IANB, however the quality of the evidence was low/moderate due to risk of bias and heterogeneity. Further studies are recommended.

Abstract
INTRODUCTION Post-operative pain and flare-up may occur in up to 58% of patients following root canal treatment. The aim was to conduct a systematic review and a possible meta-analysis to determine the effect of glucocorticosteroid (GCS) on pain following root canal treatment. METHODS AND MATERIALS Scopus, MEDLINE and CENTRAL databases were searched up to 30th January 2017 with broad key words. In addition, the reference lists in eligible papers and text books were hand-searched. Assessment of the eligibility of papers and data extraction were performed by two independent reviewers. RESULTS Of 9891 articles, 18 were recruited as eligible papers. Most of these papers showed pain reducing effect of GCS on post-endodontic pain. Because of wide heterogeneity among the recruited papers, it was not possible to perform meta-analysis. CONCLUSION Based on the results of this systematic review, there is a vast heterogeneity amongst articles regarding the use of GCS and their effect on post-operative pain after endodontic treatment. Further investigations with similar methods and materials are needed before meta-analysis on the effect of GCS on post-operative pain following root canal treatment can be performed.

Abstract
INTRODUCTION The aim of this clinical trial was to compare the degree of short term post-operative irritation after application of a triamcinolone/demeclocycyline based or a calcium hydroxide based provisional cement. METHODS A total of 109 patients (55 female and 54 male; mean age: 51 ± 14 years) with primary or secondary dentinal caries were randomly assigned to the two treatment groups of this biomedical clinical trial (phase III). Selection criteria were good systemic health and treated teeth, which were vital and showed no symptoms of pulpitis. Up to three teeth were prepared for indirect metallic restorations, and the provisional restorations were cemented with a triamcinolone/demeclocycyline (Ledermix) or a calcium hydroxide (Provicol) based material. The intensity of post-operative pain experienced was documented according to the VAS (4, 12, 20, 24, and 82 h) and compared to VAS baseline. RESULTS A total of 159 teeth were treated (Ledermix: 83 teeth, Provicol: 76 teeth). The minor irritation of the teeth, experienced prior to treatment, was similar in both groups; however, 4 h after treatment this value was significantly higher in the Provicol group than in the Ledermix group (p < 0.005, t-test). After 12 h, the difference was no longer significant. The number of patients taking analgesics for post-treatment pain was higher in the Provicol group (n = 11/53) than in the Ledermix group (n = 3/56). CONCLUSIONS The patients had no long term post-operative pain experience in both groups. However, within the first hours after cementation the sensation of pain was considerably higher in the Provicol group than in the Ledermix group.

Abstract
The purpose of this research is to investigate the frequency of endodontic flare-ups using a visual analogue scale. Definitions of flare-ups vary widely as does their reported frequency. A flare-up was defined as an increase of 20 or more points on the visual analogue scale for a given tooth, within the periods of 4 h and 24 h after the initial treatment appointment. The data from a previous study were used to determine the incidence of flare-ups after using three modalities (Ledermix, calcium hydroxide and no medication) to manage patients presenting for relief of pain of endodontic origin. A statistical analysis showed that there were no significant differences in flare-up rates at both the 4-h and 24-h periods between the three modalities. Further research is required using the above definition of a flare-up and standardising treatment protocols.

Abstract
The role of microorganisms in the development and maintenance of pulpal and periapical inflammation have been well documented. The success of root canal treatment largely depends on the elimination of microbial contamination from the root canal system. Although mechanical instrumentation of root canals can reduce bacterial population, effective elimination of bacteria cannot be achieved without the use of antimicrobial root canal irrigation and medication. This review will discuss the antimicrobial effects of the known root canal irrigants and medicaments and explore future developments in the field.

Abstract
Pain is one of the most common reasons patients seek dental treatment. It may be due to many different diseases/conditions or it may occur after treatment. Dentists must be able to diagnose the source of pain and have strategies for its management. The '3-D's' principle--diagnosis, dental treatment and drugs--should be used to manage pain. The first, and most important, step is to diagnose the condition causing the pain and identify what caused that condition. Appropriate dental treatment should then be undertaken to remove the cause of the condition as this usually provides rapid resolution of the symptoms. Drugs should only be used as an adjunct to the dental treatment. Most painful problems that require analgesics will be due to inflammation. Pain management drugs include non-narcotic analgesics (e.g., non-steroidal anti-inflammatory drugs, paracetamol, etc) or opioids (i.e., narcotics). Non-steroidal anti-inflammatory drugs (NSAIDs) provide excellent pain relief due to their anti-inflammatory and analgesic action. The most common NSAIDs are aspirin and ibuprofen. Paracetamol gives very effective analgesia but has little anti-inflammatory action. The opioids are powerful analgesics but have significant side effects and therefore they should be reserved for severe pain only. The most commonly-used opioid is codeine, usually in combination with paracetamol. Corticosteroids can also be used for managing inflammation but their use in dentistry is limited to a few very specific situations.

Abstract
Calcium hydroxide is advocated as an intracanal medication for various purposes, including prevention of posttreatment symptoms. This study assessed whether calcium hydroxide had a pain-controlling effect at different times when compared with no intracanal medication. One hundred forty patients participated. Conditions diagnosed were pulp/periapical pathosis with or without symptoms. At least partial cleaning and shaping was completed. At random, either Ca(OH)2 plus H2O paste or a dry cotton pellet was placed in the canals of half the teeth, respectively. All teeth were temporized with Intermediate Restorative Material. Patients assessed posttreatment pain up to 48 h as none, mild, moderate, or severe. The pain levels in each test group [Ca(OH)2 versus cotton pellet] at each time period were compared statistically with a multiple-regression analysis. There was no significant difference in posttreatment pain between the two groups at any time period or with any diagnosis or symptom. The use of calcium hydroxide as an intracanal medication was unrelated to the incidence and/or severity of posttreatment pain.

Abstract
AIM To investigate the relationship of postoperative pain to three different medicaments placed in the root canal after a complete biomechanical debridement of the root canal system in patients presenting for emergency relief of pain. METHODOLOGY Two hundred and twenty-three teeth belonging to 221 patients presenting as emergencies to the Royal Dental Hospital of Melbourne were included in the study. Inclusion was limited to patients with a diagnosis of pulp necrosis and acute apical periodontitis. All teeth underwent conventional root canal treatment, which involved the instrumentation to the apices of each canal at the first visit. Canals were instrumented using a stepback technique and hand-files along with irrigants using Milton's (1% sodium hypochlorite) solution followed by 15% EDTAC. The canals were dried and one of the following three medicaments was inserted into the canal in random sequence: Group 1: Ledermix paste (Lederle Pharmaceuticals, Division of Cyanamid, Wolfratshausen, Germany); Group 2: calcium hydroxide paste (Calcipulpe, Septodont, France); and Group 3: no dressing. Before dismissal, the preoperative pain experienced on the previous night was recorded using a visual analogue pain scale. Patients were then instructed to record the degree of pain experienced 4 h after treatment and daily for a further 4 days. RESULTS The mean score pain for all three groups was between 42 and 48 prior to treatment being commenced. After 4 days, the pain score for Group 2 was 10, for Group 3 was 7 and for Group 1 was 4. Mean preoperative pain level was 44.4 (of a maximum 100) for all groups, and declined by 50% (to 22.1) after 24 h. Patients in Group 1 (Ledermix) experienced significantly less (P = 0.04) postoperative pain than those in the other two groups. There was no significant difference between Group 2 (calcium hydroxide) and Group 3 (no dressing). CONCLUSION Under the conditions of this study, painful teeth with acute apical periodontitis that had been dressed with Ledermix paste gave rise to less pain than that experienced by patients who had a dressing of calcium hydroxide or no dressing at all. Ledermix is an effective intracanal medicament for the control of postoperative pain associated with acute apical periodontitis, with a rapid onset of pain reduction.

Abstract
The purpose of this prospective, double-blind, randomized study was to evaluate pain reduction using an intraosseous injection of slow-releasing methylprednisolone in teeth with irreversible pulpitis. Forty subjects presenting for emergency treatment completed the study. Each subject had a tooth with a clinical diagnosis of irreversible pulpitis with actively associated moderate to severe pain. After local anesthesia was attained, the subjects were randomly assigned to receive an intraosseous injection of either 1.0 ml of Depo-Medrol (40 mg) or 1.0 ml of sterile saline (control). No endodontic therapy was begun at the initial appointment. The subjects received ibuprofen and Tylenol #3 and completed a 7-day questionnaire on pain, percussion pain, and analgesic medications taken each day. Over the 7-day observation period, the subjects who received the intraosseous injection of Depo-Medrol reported significantly (p < 0.05) less pain and percussion pain while taking significantly (p < 0.05) fewer pain medications. Clinically the intraosseous injection of Depo-Medrol could be used to temporarily alleviate the symptoms of irreversible pulpitis until definitive treatment can be rendered.

Abstract
AIM The aims of this study were to: (i) investigate the effects of Ledermix paste as an intracanal medicament on discolouration of immature teeth, (ii) examine whether the discolouring effects were related to the method of application, (iii) examine the effects of sunlight upon discolouration of immature teeth and (iv) compare the degree of discolouration between mature and immature teeth. METHODOLOGY The root canals of 45 immature extracted human teeth were prepared and filled with either Ledermix paste, calcium hydroxide [Ca(OH)2], or saline. In group 1, Ledermix paste was only placed apical to the cemento-enamel junction (CEJ) whilst in groups 2 and 3, the paste filled the entire pulp chamber and the root canals. In group 4, Ca(OH)2 paste and in group 5, saline (control) were allowed to fill the pulp chamber and the root canals. Group 3 teeth were kept in the dark and the other groups were exposed to daylight for 12 weeks. RESULTS After 12 weeks, sunlight exposure had caused dark grey-brown staining in the Ledermix groups but this did not occur when the teeth were kept in the dark. More severe staining was noted when Ledermix paste filled the pulp chamber than when the paste was restricted to below the CEJ and when teeth were exposed to sunlight. When compared to the results of a similar study using mature teeth, the results were similar but the immature teeth were more severely stained than the mature teeth. The Ca(OH)2 paste caused an increase in lightness and yellowness in immature teeth. CONCLUSION It was concluded that Ledermix paste may cause discolouration of immature teeth. Such effects can be minimized if placement of the paste is restricted to below the gingival margin. Clinicians should ensure that Ledermix paste is not left on the walls of access cavities, especially in immature teeth.

Abstract
Thirty-six Sprague-Dawley rats were divided into three groups of 12. Group 1 was a control, whereas group 2 had the dental pulp of the first mandibular molar acutely exposed, and group 3 had dental pulp exposure for 10 days. All animals were injected with 125I-labeled dexamethasone phosphate into the right mandibular vestibule. Each group of 12 was divided into subgroups of 4 and sacrificed at 1, 2, or 4 h. The soft tissue on the buccal side and the mandible with the molars were collected and the radioactivity determined. Dexamethasone was absorbed from the injection site and distributed to the ipsilateral mandible and to the contralateral muscle and bone similarly, regardless of the treatment. Results also indicate a possible osseous affinity for this steroid, which could be beneficial in relieving the pain of intraosseous endodontic flare-ups.

Abstract
A preliminary study was conducted in a private practice office to determine the incidence of postoperative pain in 100 vital pulp cases. An ophthalmic dexamethasone-neomycin solution was introduced within the root canal during the complete cleaning and shaping procedure with the purpose of premedicating and preventing apical periodontal ligament inflammation and pain. The postoperative pain outcome was compared between cases premedicated with intracanal dexamethasone-neomycin solution alone and in combination with an oral administration of Mesulide. Moderate pain was reported in 10 cases and tooth sensitivity in 13. The clinical results indicated no report of severe pain.

Abstract
The role of intracanal medication as a root canal dressing is re-examined. In pulpectomy and some root canal treatments, where the root canal contains vital pulp tissue, it is doubtful whether a routine intracanal medicament is needed. In infected root canals, intracanal medication has been advocated for many purposes. An intracanal medicament is used to: (i) eliminate any remaining bacteria after canal instrumentation; (ii) reduce inflammation of periapical tissues and pulp remnants; (iii) render canal contents inert and neutralize tissue debris; (iv) act as a barrier against leakage from the temporary filling; (v) help to dry persistently wet canals. However, most of the indications for intracanal medicaments are questionable. Intracanal medicaments should only be used for root canal disinfection as part of controlled asepsis in infected root canals, and their role is secondary to cleaning and shaping of the root canal. Thorough canal debridement and adequate canal preparation are more pertinent, and their importance is emphasized. Bacteriological sampling may be necessary if a tooth does not respond to treatment, to help in the choice of intracanal medicament.

Abstract
The purpose of this study was to histologically investigate steroid effects on the dental pulp. Three steroid preparations, hydrocortisone, betamethasone and triamcinolone, were locally applied to the exposed pulp tissue in rat incisor after pulpectomy. After 24 h, the effects on the tissues were assessed by light microscopy. The results showed that topical application of corticosteroids as an intracanal medicament reduced inflammatory changes in the pulp as compared with controls. Furthermore, triamcinolone and betamethasone demonstrated more potent anti-inflammatory effects than did hydrocortisone.

Abstract
To determine whether the posttreatment prophylactic use of diflunisal (Dolobid 500) would be more effective than the on-demand use of diflunisal in reducing endodontic posttreatment pain, the current open-label, randomized study was undertaken. After one-visit nonsurgical endodontic therapy, 100 patients with asymptomatic teeth having either vital-inflamed pulp, pulpal necrosis, or pulpal necrosis with periapical radiolucent lesion were randomly given either prophylactic diflunisal (two tablets immediately at the conclusion of the visit, then four tablets to be taken in the schedule of one every 8 to 12 hours for pain if needed) or on-demand diflunisal (same dosage schedule; pills to be taken only if needed). The outcome showed that compared to the on-demand usage, the posttreatment prophylactic administration of diflunisal resulted in a statistically significant reduction in the number of episodes of endodontic posttreatment pain that required analgesic intervention. It appears from the results of this study that the posttreatment prophylactic use of diflunisal is significantly more effective than the on-demand usage of diflunisal in reducing endodontic posttreatment pain for one-visit endodontic therapy with all types of originally asymptomatic endodontic conditions. Further studies are necessary to determine whether pretreatment prophylactic deflunisal would be more effective, and also the effectiveness of prophylactic diflunisal in reducing posttreatment pain in presenting symptomatic cases and for cases treated in multiple visits.

Abstract
A questionnaire was sent to diplomates of the American Board of Endodontics to determine changing trends in the treatment of endodontic emergencies since Dorn's survey 10 yr ago. There is a definitely greater trend toward complete instrumentation of the root canals to the apex regardless of the emergency condition than there was a decade ago. The number of respondents who leave teeth open when the pulp is nonvital has dropped dramatically in the past decade. When there is no periapical involvement, over one third of the respondents are completing treatment in one visit. A decrease in the use of classic phenolic medicaments was noted with a corresponding increase in calcium hydroxide or no medication at all.

Abstract
Dilutions of Ledermix paste, Pulpdent paste and a mixture of equal parts by weight of Ledermix paste and Pulpdent paste were added to in vitro cultures of mouse fibroblasts or bacteria for 24 h, and various cell functions were then examined: mitosis in and survival of fibroblasts, and survival of Lactobacillus casei or Streptococcus mutans. Ledermix was found to reversibly inhibit mitosis while present in the concentrations range 10(-3) to 10(-6) mg/ml. Mixing with Pulpdent did not modify this antimitotic effect. Ledermix killed mouse fibroblasts at 10(-3) mg/ml and above, while Pulpdent killed at 1 mg/ml and above. The toxic effect of Ledermix was slightly inhibited by mixing it with Pulpdent. Ledermix killed S. mutans at about the same concentration at which it killed the mammalian cells, but required a one thousand-fold greater concentration to kill L. casei. Pulpdent killed both L. casei and S. mutans at approximately one-fifth of the concentration at which it killed the mammalian cells. Pulpdent slightly potentiated the antibacterial effect of Ledermix. The pH of Pulpdent was reduced by approximately 0.3 units by mixing with Ledermix. The present data showed that the 50:50 mix of Ledermix and Pulpdent retained the properties examined that are thought to be of therapeutic benefit, while not increasing the toxicity of the component parts to mammalian cells.

Abstract
To determine whether a relatively large dose of oral dexamethasone given for a short period of time would be effective in reducing endodontic interappointment pain, the current double-blind, placebo-controlled study was undertaken. After the visit for instrumentation, 40 patients with asymptomatic teeth having vital-inflamed pulps were randomly given either dexamethasone (3 tablets of 4 mg each) or a dextrose placebo identical in appearance (same dosage schedule). The outcome showed that the oral administration of dexamethasone resulted in a statistically significant reduction in endodontic interappointment pain at all three time periods evaluated, that is, at 8 hours, 24 hours, and 48 hours (p less than 0.01). It appears from the results of this study that this dosage schedule of oral dexamethasone is sufficient to significantly reduce endodontic interappointment pain for teeth with asymptomatic vital-inflamed pulps. Further studies are needed for teeth with other endodontic pulpal-periapical conditions and for symptomatic teeth.
