Abstract
INTRODUCTION Most pain studies have been based on a postsurgical, third molar model using ibuprofen (IBU)/acetaminophen (APAP). Studies have found quicker onset of pain relief with a newer formulation of IBU - ibuprofen sodium dihydrate (ISD). The purpose of this study was to compare pain reduction of ISD/APAP to ISD in an acute endodontic pain model of untreated patients experiencing moderate to severe pain with symptomatic apical periodontitis. METHODS AND MATERIALS In this double-blind randomized study, 64 adult emergency patients in acute moderate to severe pain, a pulpal diagnosis of symptomatic irreversible pulpitis or necrosis, and symptomatic apical periodontitis participated. Each patient randomly received either one dose of 768 mg ISD/1000 mg APAP or one dose of 768 mg ISD. Pain intensity scores were recorded every 15 minutes over 240 minutes using the Heft-Parker VAS along with time to first sign of pain relief, time to meaningful pain relief, and time to 50% pain relief also recorded. The data were analyzed statistically. RESULTS Both ISD and ISD/APAP groups showed a progressive decrease in pain from baseline to 120 minutes after medication administration. Afterward, a relative plateau was seen in the patients' pain. There was no difference in the VAS scores between the ISD and ISD/APAP at any given time point, time to first sign of pain relief, time to meaningful pain relief, and time to 50% pain relief. CONCLUSIONS The addition of APAP to ISD for pain control in an untreated endodontic pain model did not differ significantly from ISD alone.

J Endod 2024:S0099-2399(24)00347-9. [PMID: 38880472 DOI: 10.1016/j.joen.2024.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 05/28/2024] [Accepted: 06/07/2024] [Indexed: 06/18/2024]
Abstract
INTRODUCTION This study systematically reviewed literature regarding the effect of different concentrations of sodium hypochlorite (NaOCl) used during root canal treatment (RCT) on post-endodontic pain (PEP) and rescue analgesia. METHODS Following registration with PROSPERO (CRD42023388916), a search was conducted using PubMed, Scopus, Web of Science, and Embase databases. Randomized controlled trials (RaCTs) of patients receiving RCT which assessed PEP at different time intervals were included. Following data extraction and Cochrane risk of bias assessment 2, meta-analyses were performed to evaluate PEP during the first 48h along with rescue analgesic intake. The certainty of the evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation approach. RESULTS Five RaCTs with 674 patients were included. One study exhibited a low risk of bias, while four raised some concerns. Patients treated with low concentrations of NaOCl (≤3%) were significantly less likely to report PEP at 24h (OR=2.32; [95%CI, 1.63-3.31]; P<0.05) and 48h (OR=2.49; [95% CI,1.73-3.59]; P<0.05) as compared with high concentrations of NaOCl (≥5%). Furthermore, with low concentrations of NaOCl, significantly lesser moderate-severe PEP was reported at 24h (OR=2.32; [95%CI, 1.47-3.62]; P<0.05) and 48h (OR=2.35; [95%CI, 1.32-4.16]; P<0.05) and lesser analgesia was needed (OR=2.43; [95%CI, 1.48-4.00]; P<0.05). CONCLUSIONS While PEP can be influenced by several factors, low certainty evidence suggests that when NaOCl is used as an irrigant during RCT, PEP may be less likely with lower concentrations of NaOCl. Moderate certainty evidence indicates that lesser analgesia may be required with lower concentrations of NaOCl. These results should be cautiously interpreted.

Abstract
This systematic review and meta-analysis aimed to determine whether apical patency increases postoperative pain after endodontic therapy. This study explored the degree and incidence of postoperative pain during root canal therapy, as well as the number of required analgesic doses. We searched PubMed, Scopus, Embase, Web of Science, Cochrane Library, and gray literature from the date of database inception until May 2023. RevMan 5.4 software was used for data analysis. Twelve studies were considered eligible for meta-analysis. The mean pain scores on days 1 (mean difference [MD] = -1.69) and 2 (MD = -0.85) differed significantly between the apical patency and non-patency groups. The odds for pain after 24 h were significantly lower (OR 0.59) in the apical patency group than in the non-patency group. Furthermore, the mean number of required analgesic doses was not significantly different between the two groups. In conclusion, apical patency significantly alleviated postoperative pain (low-quality evidence) and reduced the incidence of pain (moderate evidence). However, high-quality randomized controlled trials are required to validate these findings.

Analysis of Pediatric Pulpotomy, Pulpectomy, and Extractions in Primary Teeth Revealed No Significant Association with Subsequent Root Canal Therapy and Extractions in Permanent Teeth: A Retrospective Study. Pediatr Rep 2024; 16:438-450. [PMID: 38921703 PMCID: PMC11206693 DOI: 10.3390/pediatric16020038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2024] [Revised: 05/23/2024] [Accepted: 05/29/2024] [Indexed: 06/27/2024] Open
Abstract
Recent evidence suggests that an ever-growing number of pediatric patients require invasive treatments such as root canal therapy (RCT) in their permanent dentition, albeit with little information about risk factors such as prior invasive treatments of pulpotomy or pulpectomy in their primary dentition. Therefore, the primary objectives of this study were to determine the number of pediatric patients who have had any type of invasive treatment in their primary teeth, to assess their association with any subsequent invasive treatment (root canal therapy, extractions) in their permanent dentition, and to assess these trends over time. This retrospective study utilized summary data from a clinical pediatric patient pool (ages 0-17) over the period of 2013-2022. This analysis revealed that pediatric patients requiring pulpotomies and pulpectomies in primary dentition declined between 2013 (n = 417, n = 156) and 2022 (n = 250, n = 12), while root canal therapy (RCT) in permanent dentition increased six-fold from n = 54 to n = 330. In addition, few (7.8%) patients with RCT had a previous history of pulpotomy or pulpectomy, which suggests that invasive treatments performed in primary dentition have no direct association with the subsequent need for invasive treatments in permanent dentition, although more research is needed to determine the explanations for these observations.

Abstract
BACKGROUND Symptomatic irreversible pulpitis often results in heightened reactions to thermal stimuli such as pain evoked by a cold stimulus, and spontaneous odontogenic pain (unprovoked pain). OBJECTIVE This study primarily compared the clinical manifestations of odontogenic spontaneous pain and pain provoked by cold stimulus specifically focusing on their sensory discriminative characteristics (intensity, duration and quality) between symptomatic irreversible pulpitis patients with and without referred pain. METHODS Twenty-three patients with symptomatic irreversible pulpitis with referred pain and 12 patients without referred pain were included in this cross-sectional study. The following outcomes were assessed: odontogenic spontaneous pain and its descriptors; pain evoked by cold stimulus and qualitative sensory testing before and after local anaesthesia; referred pain location; use of analgesic medication; complementary anaesthesia efficacy. T-test, chi-squared and McNemar tests were applied to the data (p < .50). RESULTS Patients with referred pain presented a greater odontogenic pain intensity (p < .05) when considered the average of the last 24 h. These patients also showed higher pain rating and pain descriptors (p < .05). Intensity and duration of the pain evoked by cold stimulus in the non-affected contralateral tooth at baseline were higher for patients with referred pain (p < .05). CONCLUSION Symptomatic irreversible pulpitis patients with referred pain present greater odontogenic spontaneous pain and a heightened pain sensitivity. Therefore, patients with referred pain seem more complex from a pain severity perspective, supporting the clinical utility of discriminating symptomatic irreversible pulpitis with and without referred pain.

Increased Purinergic Signaling in Human Dental Pulps With Inflammatory Pain is Sex-Dependent. THE JOURNAL OF PAIN 2024; 25:1039-1058. [PMID: 37956743 PMCID: PMC11129867 DOI: 10.1016/j.jpain.2023.10.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 09/22/2023] [Accepted: 10/28/2023] [Indexed: 11/15/2023]
Abstract
An enhanced understanding of neurotransmitter systems contributing to pain transmission aids in drug development, while the identification of biological variables like age and sex helps in the development of personalized pain management and effective clinical trial design. This study identified enhanced expression of purinergic signaling components specifically in painful inflammation, with levels increased more in women as compared to men. Inflammatory dental pain is common and potentially debilitating; as inflammation of the dental pulp can occur with or without pain, it provides a powerful model to examine distinct pain pathways in humans. In control tissues, P2X3 and P2X2 receptors colocalized with PGP9.5-positive nerves. Expression of the ecto-nucleotidase NTPDase1 (CD39) increased with exposure to extracellular adenosine triphosphate (ATP), implying CD39 acted as a marker for sustained elevation of extracellular ATP. Both immunohistochemistry and immunoblots showed P2X2, P2X3, and CD39 increased in symptomatic pulpitis, suggesting receptors and the ATP agonist were elevated in patients with increased pain. The increased expression of P2X3 and CD39 was more frequently observed in women than men. In summary, this study identifies CD39 as a marker for chronic elevation of extracellular ATP in fixed human tissue. It supports a role for increased purinergic signaling in humans with inflammatory dental pain and suggests the contribution of purines shows sexual dimorphism. This highlights the potential for P2X antagonists to treat pain in humans and stresses the need to consider sex in clinical trials that target pain and purinergic pathways. PERSPECTIVE: This article demonstrates an elevation of ATP-marker CD39 and of ATP receptors P2X2 and P2X3 with inflammatory pain and suggests the rise is greater in women. This highlights the potential for P2X antagonists to treat pain and stresses the consideration of sexual dimorphism in studies of purines and pain.

Abstract
Background This review aims to perform a complete evaluation of the impact of photobiomodulation (PMB) on postoperative endodontic pain. Materials and Methods The PRISMA checklist was used to perform this systematic review. The electronic databases were searched, including Google Scholar, PubMed, and Embase. Sixty-three papers were obtained through a main electronic search and a hand search. Nine trials met the criteria after screening the titles, abstracts, and/or full texts. Results Seven out of nine studies showed that PMB has a significant impact on relieving postoperative endodontic pain, with no statistically significant difference in the severity of pain between the laser and control groups in the two remaining studies. In addition, eight studies showed no adverse effects, indicating that we can remove the adverse effects of drugs such as nonsteroidal anti-inflammatory drugs. However, one study showed evidence of the consequences of PMB application on teeth with symptomatic irreversible pulpitis. Therefore, it can be concluded that PMB should not be used in teeth with pain because of irreversible pulpitis. Conclusion Although there is some understanding from a cellular viewpoint of the effects of PMB, there is still some uncertainty about whether these cell-level modifications impact reducing the postendodontic pain.

Abstract
OBJECTIVE To evaluate the influence of dental anxiety on the perception of pain before and during endodontic treatments. MATERIALS AND METHODS The PRISMA checklist was followed. A search was conducted in Scopus, Medline/PubMed, The Cochrane Library, and Web of Science databases. Based on PECOS criteria, the first outcome was a possible association between pre-operative pain and anxiety. The second outcome was a possible association between intraoperative pain and anxiety. The type of studies was observational. The JBI Critical Appraisal Checklist was used to evaluate the methodological quality of articles. The certainty of the evidence was analyzed using the GRADE approach. RESULTS Four articles were included with a total of 471 patients. Two studies found a positive association between pain and pre-endodontic treatment anxiety. Three studies investigated the relationship between anxiety and intraoperative pain; two identified an extremely significant positive association. One article noted that anxiety influences pain expectancy. The studies were of good quality as assessed by the JBI Critical Appraisal Checklist for cross-sectional studies. However, the certainty of the evidence was considered low and very low. CONCLUSIONS Dental anxiety can be directly associated with pre- and intraoperative pain during endodontic procedures. CLINICAL RELEVANCE It is necessary to identify patients with dental anxiety to employ therapies to bring their anxiety under control, avoiding the increase of endodontic infections, and the postponement and evasion of endodontic treatments.

Abstract
BACKGROUND Preoperative pulpal status may influence the outcomes of root canal treatment (RCTx) according to various measures used. OBJECTIVES To compare the effectiveness of RCTx of teeth with a vital pulp versus a necrotic pulp, using a range of clinical and patient-related outcomes proposed for the development of S3-level clinical practice guidelines. METHODS A search was conducted in the PubMed-MEDLINE, Scopus, EMBASE, Google scholar databases and available repositories, followed by hand searches, until 29 March 2022. Clinical studies published in the English language comparing the stipulated outcomes of RCTx of teeth with vital versus necrotic pulp were included. The Newcastle-Ottawa Scale was adapted to assess study quality. Effects of pulpal status were estimated and expressed as risk ratio (RR) using fixed- and random-effect meta-analyses. The quality of evidence was assessed through the Grading of Recommendations Assessment, Development and Evaluation tool. RESULTS Twenty-eight studies published between 1961 and 2021 were included. Five studies have investigated the "tooth survival" outcome, four reported pulpal status was not a significant predictor, consistent with meta-analysis findings (RR: 1.00; 95% CI: 1.00, 1.00; n = 3). Seven studies reported pulpal status had no significant influence on postoperative pain, regardless of duration after treatment. Sixteen studies have analysed "periapical health," and 11 revealed pulpal status had no significant influence. Meta-analyses revealed the influence was not significant if preoperative periapical radiolucency was absent (RR: 0.95; 95% CI: 0.90, 1.00; n = 9) but significant if it was present (RR: 1.12; 95% CI: 1.05, 1.19; n = 11). Most studies were classified as "some concerns" (n = 17) to "low" (n = 9) risk of bias RoB. DISCUSSION Evidence is limited and only available for three outcomes when comparing the effectiveness of RCTx in permanent teeth with vital pulp versus pulp necrosis. Nevertheless, the quality of available evidence was moderate to high. The "periapical health" data heterogeneity could be explained by preoperative radiolucency, thus RCTx was found more effective for prevention than the resolution of apical periodontitis. CONCLUSIONS There was no significant difference in the "tooth survival," "postoperative pain" and "evidence of apical radiolucency" outcomes of RCTx in teeth with vital or necrotic pulps.

Doğramacı EJ, Rossi-Fedele G. Patient-related outcomes and Oral Health-Related Quality of Life in endodontics. Int Endod J 2023; 56 Suppl 2:169-187. [PMID: 36102371 DOI: 10.1111/iej.13830] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 09/08/2022] [Accepted: 09/09/2022] [Indexed: 11/30/2022]
Abstract
There is increased interest in outcome measures that complement the classic goal of endodontics, being the prevention and healing of apical periodontitis. Possible outcome measures can be subdivided into patient-centred outcomes (PCOs), encompassing data collected by nonpatients aiming to assess the effectiveness of an intervention and patient-reported outcomes (PROs), which are reported directly by the patient. PROs can be subsequently classed into PRO measures that ascertain patients' view of their symptoms, their functional status, and their health-related quality of life, and patient-reported experience measures that focus on aspects including the humanity of care, patient satisfaction, patient preference and adherence, personal costs, expectation fulfilment, and decision regrets. The present review aims to define various patient-related outcomes and discuss the literature available regarding PCOs and PROs in endodontics. This includes those proposed to assess the effectiveness of endodontic treatment for pulpitis and apical periodontitis for use in the development of European Society of Endodontology S3-level clinical practice guidelines that have been included by all working groups, except for the radiographic assessment of apical periodontitis. Based on limited evidence in the field, it can be summarized that after recall periods of various lengths, endodontic treatment is associated with a high likelihood of tooth survival and limited need for further intervention, including extraction and further restorative procedures. Oral Health-Related Quality of Life (OHRQoL) is likely to improve following the completion of treatment. Nonetheless, the literature assessing the association between OHRQoL and endodontics is hampered by the use of instruments that have not been previously validated. Amongst the remaining outcome measures discussed in the present review, it is worth highlighting that there is only one study assessing exacerbations in teeth with the presence of endodontic pathosis, which suggests a very low incidence of this adverse effect following endodontic treatment. Patients' expectation fulfilment, adherence, and satisfaction are closely inter-related and depend also on various nonclinical factors. Further studies assessing PCOs and PROs, in association with healing and prevention of apical periodontitis, are required to better understand endodontic treatment from the perspective of patients.

J Clin Exp Dent 2023; 15:e149-e159. [PMID: 36911155 PMCID: PMC9994658 DOI: 10.4317/jced.59941] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 09/05/2022] [Indexed: 01/16/2023] Open
Abstract
Background Post-endodontic pain (PEP) management is an important factor to be considered in endodontic treatment. Several risk factors have been described that can attribute to its appearance. Laser-assisted disinfection has been described by many authors for its antimicrobial effect. Few studies described the relation between laser disinfection and its effect on PEP. The objective of this review is to describe the relation between different intracanal laser disinfection techniques and their effects on PEP. Material and Methods An electronic search strategy was performed in Pubmed, Embase, and Web of Science (WOS) databases without restrictions as to the date of publication. Eligibility criteria were randomized controlled clinical trials (RCT) that used one of the different intracanal laser disinfection techniques in their experimental groups evaluating PEP outcome were included. Risk of bias analysis was performed by the Cochrane risk of bias tool. Results The initial research identified 245 articles from which 221 were excluded and 21 studies were sought for retrieval and 12 articles met our inclusion criteria for the final qualitative analysis. The laser systems used were Nd:YAG, Er:YAG and, diode lasers including photodynamic therapy. Conclusions The diode lasers showed the most promising results in terms of PEP reduction while Er:YAG showed more short-term efficacy (6 hours postoperative interval). The variables could not be analyzed homogenously due to the differences in the study designs. More RCT are needed comparing different laser disinfection techniques with the same baseline endodontic pathology to establish a specific protocol for the best outcome. Key words:Root canal treatment, Post-endodontic pain, Intracanal laser disinfection, laser dentistry.

Developments and Performance of Artificial Intelligence Models Designed for Application in Endodontics: A Systematic Review. Diagnostics (Basel) 2023; 13:diagnostics13030414. [PMID: 36766519 PMCID: PMC9913920 DOI: 10.3390/diagnostics13030414] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 01/18/2023] [Accepted: 01/20/2023] [Indexed: 01/26/2023] Open
Abstract
Technological advancements in health sciences have led to enormous developments in artificial intelligence (AI) models designed for application in health sectors. This article aimed at reporting on the application and performances of AI models that have been designed for application in endodontics. Renowned online databases, primarily PubMed, Scopus, Web of Science, Embase, and Cochrane and secondarily Google Scholar and the Saudi Digital Library, were accessed for articles relevant to the research question that were published from 1 January 2000 to 30 November 2022. In the last 5 years, there has been a significant increase in the number of articles reporting on AI models applied for endodontics. AI models have been developed for determining working length, vertical root fractures, root canal failures, root morphology, and thrust force and torque in canal preparation; detecting pulpal diseases; detecting and diagnosing periapical lesions; predicting postoperative pain, curative effect after treatment, and case difficulty; and segmenting pulp cavities. Most of the included studies (n = 21) were developed using convolutional neural networks. Among the included studies. datasets that were used were mostly cone-beam computed tomography images, followed by periapical radiographs and panoramic radiographs. Thirty-seven original research articles that fulfilled the eligibility criteria were critically assessed in accordance with QUADAS-2 guidelines, which revealed a low risk of bias in the patient selection domain in most of the studies (risk of bias: 90%; applicability: 70%). The certainty of the evidence was assessed using the GRADE approach. These models can be used as supplementary tools in clinical practice in order to expedite the clinical decision-making process and enhance the treatment modality and clinical operation.

Abstract
Introduction This study aimed to compare the efficacy of ibuprofen, Novafen, mefenamic acid (MA), and celecoxib for pain relief in patients with symptomatic irreversible pulpitis prior to emergency endodontic treatment. Materials and Methods This clinical trial was conducted on 120 patients with moderate to severe pain due to symptomatic irreversible pulpitis seeking emergency endodontic treatment. The patients were randomly divided into 4 groups to receive Novafen, MA, Celecoxib, and ibuprofen. The pain score of patients was measured before and 1 hour after analgesic intake using a visual analog scale (VAS). The success of analgesic treatment was analyzed by the binary logistic regression model. Results A total of 117 patients including 76 females and 41 males with a mean age of 30.29 years completed the study and were statistically analyzed. Ibuprofen had the highest analgesic efficacy followed by Novafen, and caused a significantly greater reduction in pain score compared with MA and celecoxib [OR (Ibuprofen vs MA)=1.28, OR (Ibuprofen vs Celecoxib)=3.74, OR (Novafen vs MA)=2.94, OR (Novafen vs Celecoxib)=2.94, P<0.05]. Ibuprofen and Novafen had no significant difference in analgesic efficacy (P>0.05). Baseline pain score was a predictive factor for the success of analgesics (P<0.05). The success of analgesic treatment decreased by 0.68 times with each unit increase in pain score (P<0.05). Gender and age of patients had no significant effect on success of analgesics (P>0.05). Conclusion Both ibuprofen and Novafen can serve as the analgesics of choice for pain relief in patients with symptomatic irreversible pulpitis with moderate to severe pain when emergency endodontic treatment cannot be immediately performed.

Abstract
Introduction This randomized clinical trial aimed to determine whether the XP-endo finisher combined with or without foraminal enlargement has any significant effect on the incidence and intensity of postoperative pain in necrotic pulps. Materials and Methods Clinical pain levels were measured after 6, 12, 24, 48, and 72 hours and at 7 postoperative days. All treatments were performed by an endodontist in a single visit. One hundred and twenty patients were included. All patients had a single tooth treated. The patients were divided into four groups: No FE (None Foraminal Enlargement) (n=30), FE (Foraminal Enlargement) (n=30), No FE+XPF (None Foraminal Enlargement+XP-endo Finisher) (n=30) and XPF+FE (XP-endo Finisher and Foraminal Enlargement) (n=30). The canals were irrigated with sodium hypochlorite, shaped using WaveOne Gold Medium file, and then filled by using a matching single cone and AH-Plus sealer. The cavity was filled using glass ionomer cement. Pain intensity was assessed using the visual analog scale. The data were analyzed with the ANOVA and Games-Howell test. The significance level was 5%. Results The XPF+FE group experienced a higher level of pain, being classified on the visual analog scale as moderate for 48 postoperative hours and mild for 7 postoperative days (P<0.05). In the other groups, the pain was mild, only with different time intervals (P>0.05). Conclusions Foraminal enlargement associated with XP-endo Finisher may cause moderate postoperative pain.

Abstract
OBJECTIVES This study developed predictive models for one-week acute and six-month persistent pain following root canal treatment (RCT). An additional aim was to study the gain in predictive efficacy of models containing clinical factors only, over models containing sociodemographic characteristics. METHODS A secondary data analysis of 708 patients who received RCTs was conducted. Three sets of predictors were used: (1) combined set, containing all predictors in the data set; (2) clinical set and (3) sociodemographic set. Missing data were handled by multiple imputation using the missing indicator method. The multilevel least absolute selection and shrinkage operator (LASSO) regression was used to select predictors into the final multilevel logistic models. Three measures, the area under the receiver operating characteristic curve (AUROC) and precision-recall curve (AUPRC) and calibration curves, were used to assess the predictive performance of the models. RESULTS The selected-in factors in the final models, using LASSO regression, are related to pre- and intra-treatment clinical symptoms and pain experience. Predictive performance of the models remained the same with the inclusion (exclusion) of the socio-demographic factors. For predicting one-week outcome, the model built with combined set of predictors yielded the highest AUROC and AUPRC of 0.85 and 0.72, followed by the models built with clinical factors (AUROC = 0.82, AUPRC = 0.66). The lowest predictive ability was found in models with only sociodemographic characteristics (AUROC = 0.68, AUPRC = 0.40). Similar patterns were observed in predicting six-month outcome, where the AUROC for models with combined, clinical and sociodemographic sets of predictors were 0.85, 0.89 and 0.66, respectively, and the AUPRC were 0.48, 0.53 and 0.22, respectively. CONCLUSIONS Clinical factors such as the severity and experience of pre-operative and intra-operative pain were discovered important to the subsequent development of pain following RCTs. Adding sociodemographic characteristics to the models with clinical factors did not change the models' predictive performance or the proportion of explained variance.

Severity of Post-Operative Pain after Instrumentation of Root Canals by XP-Endo and SAF Full Sequences Compared to Manual Instrumentation: A Randomized Clinical Trial. J Clin Med 2022; 11:jcm11237251. [PMID: 36498825 PMCID: PMC9740715 DOI: 10.3390/jcm11237251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 11/27/2022] [Accepted: 12/03/2022] [Indexed: 12/12/2022] Open
Abstract
This investigation aimed to examine the post-operative pain experienced following single-visit root canal treatment using the XP-endo shaper sequence (XPS), full-sequence self-adjusting file (SAF), and manual K-files (HKF). A randomized equivalence parallel design, double-blinded clinical study was conducted on 120 patients with symptomatic irreversible pulpitis, with or without clinical signs of apical periodontitis. Only teeth with fully formed roots and no periapical lesions were incorporated in the study. Patients were apportioned to one of three groups (n = 40) randomly: Group 1-XPS, Group 2-SAF, and Group 3-HKF. Pre- and post-instrumentation pain was rated utilizing Visual Analog Scale (VAS) with a spectrum of 0-100 mm. The descriptive statistics and one-way ANOVA with 95% confidence intervals were used for statistical analysis. The mean VAS scores before instrumentation were consistent in all three groups. At 6, 24, 48, and 72 h, patients with root canals instrumented by SAF had the lowest post-instrumentation mean VAS score, followed by XPS. For all time intervals, the patients in the HKF group had the highest VAS score. The full-sequence SAF instrumentation resulted in less post-operative pain than the XP-endo plus protocol, while manual instrumentation with K-files resulted in the highest post-operative pain.

Abstract
This study evaluated the perceived vibration, noise and discomfort levels associated with two nickel-titanium file systems with different kinetics; reciprocating motion (REC) using WaveOne Gold and continuous rotation motion (CON) using ProTaper NEXT. Forty roots with two canals from maxillary premolar and molar of 40 patients were included. Root canals were instrumented using each system for each canal. Patients were surveyed about the vibration, noise and discomfort experienced using visual analogue scale, and their preference. The responses were statistically analysed using Wilcoxon Signed-Rank test, Mann-Whitney U test and Spearman's rank correlation test at the 95% of significance level. The vibration, noise and discomfort experienced were significantly greater in REC than CON (P < 0.05). In REC, male subjects reported significantly higher vibration than female (P < 0.05). Majority respondents (72.5%) preferred the CON method. The perceived vibration, noise and discomfort were less apparent from the CON than the REC.

Abstract
Background Postoperative pain can occur because of residual infection even after effective chemomechanical preparation. This study aimed to compare postoperative pain after chemomechanical preparation with placebo and laser irradiation in nonvital teeth having symptomatic apical periodontitis. Materials and Methods Sixty (n = 30) participants after obtaining written consent were enrolled in the study. In Group 1, chemomechanical preparation followed by mock laser therapy was carried out in which laser tip was applied but not activated. In Group 2, chemomechanical preparation followed by a laser irradiation was applied and activated. Postoperative pain scores were evaluated at baseline, 24 h, 48 h, and 72 h using the Visual Analog Scale. Preoperative and postoperative percussion pain scores were also recorded. Subjects needing rescue medication were recorded as well. Mann-Whitney U test and Wilcoxon test were used for intergroup comparison and intragroup comparison. The Chi-square test was used for comparing rescue medication. Results There was significant reduction in pain scores in the laser group as compared to placebo group at all time points. There was also significant difference in the preoperative and postoperative percussion pain scores. 9 and 3 subjects required rescue medication in Groups 1 and 2, respectively. Conclusion Laser irradiation following chemomechanical preparation led to significant reduction in postoperative pain and can be considered as a valuable adjunct.

Abstract
Endodontic treatment comprises the overall management of pre-, intra- and post-operative symptoms, including post-operative endodontic pain, considered as a complication susceptible of chronicization. Post-operative pain is very common and highly unpreventable and has a multi-factorial etiology and a potential pathogenic link to the acute inflammation of the periapical area, secondary to localized chemical, mechanical, host and/or microbial damage occurring during endodontic treatment. Considering the multitude of heterogeneous technical and pharmacological approaches proposed to control post-operative endodontic pain, the present study primarily comprised an overview of systematic reviews of systematic reviews of randomized clinical trials, summarizing findings on post-operatively administered oral medications for post-operative endodontic pain control, in order to note the most effective type and dosage of such drugs. Secondarily, a narrative review of the current evidence on technical solutions to be observed during endodontic treatment procedures, to control post-operative pain, was conducted to provide integrated evidence-based clinical recommendations for optimal post-operative endodontic pain management.

Abstract
Two fundamental goals of endodontic treatment are to prevent or treat apical periodontitis. From a predictive perspective, several variables can affect the outcome of root canal treatment. Some of these variables depend on intraoperative factors, which include irrigation technique, size of the apical preparation, use of intracanal medicaments or the number of appointments necessary to complete the treatment. However, the outcome may also be affected by host and microbial factors. The intensity of periradicular bone loss or tissue damage, the presence of preoperative pain and associated conditions such as mechanical allodynia and central sensitization, the anatomical complexity of the apical portion of the canal, and the virulence and longevity of the bacterial infection can all have a profound influence on the outcome. Furthermore, numerous medical conditions have been reported to decrease the capability of the immune system to heal the periapical tissues. It is the clinician's responsibility to analyse these variables and incorporate them into the disinfection strategy to maximize the chances of healing. This narrative review will focus on the present status of intracanal medicaments, the clinical indications for their use and future directions for research.

Abstract
Endodontic emergencies are common in both general dental practices and specialist Endodontic practices. The aim of this review is to provide an overview of endodontic emergencies. Endodontic emergencies can be a result of many different conditions of the pulp, root canal and periradicular tissues. They may occur before endodontic treatment has been started, between appointments when treatment is being performed over multiple visits, or after endodontic treatment has been completed. In the latter situation, the emergency may be very soon after the treatment or it may occur many years later, in which case it is usually a new disease process as a result of the root canal system becoming infected. An emergency can be a stressful situation for both the patient and the dentist (or endodontist) as it is usually an unexpected event. It is incumbent on dental professionals to provide timely assistance to patients who have an emergency, and it is also important to allow sufficient time to manage the situation comprehensively. Management of endodontic emergencies should follow the principles of the 3D's - Diagnosis, Definitive dental treatment and Drugs - and in that sequence. An accurate diagnosis, the first "D", is essential so the appropriate treatment can be provided. Diagnosis requires a thorough understanding of the various conditions that can cause the emergency and this can be helped by having a comprehensive classification of the various conditions. The diagnosis should also direct the clinician to the appropriate definitive dental treatment, the second "D". Root canal treatment will not always be required as some cases can be managed conservatively. Other cases may require root canal re-treatment. The specific details of how the treatment is done can also vary, according to the diagnosis. The final "D" is Drugs - the use of drugs should also be dependent on the diagnosis and the dental treatment. Drugs should only be an adjunct following the treatment. The clinician must also differentiate between inflammation and infection in order to provide the appropriate treatment and to prescribe the appropriate medication for effective pain relief and resolution of other symptoms or signs such as swelling.

[PMID: 34792207 PMCID: PMC9300172 DOI: 10.1111/iej.13664] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 11/13/2021] [Accepted: 11/15/2021] [Indexed: 11/27/2022]
Abstract
Aim To assess whether persistent idiopathic dentoalveolar pain (PIDAP), a diagnosis of exclusion, exhibits common features that can facilitate its diagnosis. PIDAP is defined by the International Classification of Orofacial Pain (ICOP 6.3.) as ‘Persistent unilateral intraoral dentoalveolar pain, rarely occurring in multiple sites, with variable features but recurring daily for more than 2 h per day for more than 3 months, in the absence of any preceding causative event’. Methodology In this observational study, participants fulfilling the new ICOP diagnostic criteria of PIDAP were included, covering 16 years of consecutive data. A systematic, retrospective assessment of patients utilizing the new PIDAP criteria on complaints of chronic tooth pain in a referral‐based endodontic practice was undertaken. Non‐idiopathic cases were excluded on the basis of clinical and radiologic findings. A modified neuropathic pain questionnaire was used to describe the painful sensations. Furthermore, allodynia in the periodontal space and sensory changes in the oral mucosa were assessed using a periodontal probe. Results Amongst the 160 patients assessed, 78 (63 women) fulfilled the strict PIDAP criteria. Pain history of PIDAP included no nocturnal awakening (85%) and a ‘pulling/dragging’ pain quality (59%). In 69% of the patients with PIDAP, pain was associated with a root filled tooth at the same site. In 14% of the cases, no endodontic treatment was performed in the affected quadrant. Mechanical allodynia in the gingival sulcus was observed in 91% of patients with painful teeth or implants. Conclusions In this observational study, PIDAP mainly affected females and was associated with undisturbed sleep and periodontal allodynia.

Clinical and microbiological effects of ultrasonically activated irrigation versus syringe irrigation during endodontic treatment: a systematic review and meta-analysis of randomized clinical trials.

[PMID: 34729673 DOI: 10.1007/s10266-021-00671-8] [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: 08/11/2021] [Accepted: 10/19/2021] [Indexed: 11/26/2022]
Abstract
This study aimed to systematically review clinical and microbiology-related effects of ultrasonically activated irrigation (UAI) compared to syringe irrigation (SI) during endodontic treatment. Electronic databases searching and manual searching were conducted. Only randomized clinical trials (RCTs) were included comparing UAI to SI. The RoB 2.0 Cochrane tool was used for risk-of-bias (RoB) assessment. The main outcomes were postoperative pain, treatment failure, and microbiology-related outcomes. Qualitative and quantitative analyses, wherever applicable, were performed. Risk ratios (RR) and [standardized] mean differences {[S]MD} were calculated for dichotomous and continuous outcomes, respectively. Certainty of evidence (CoE) was assessed using GRADE tool. Ten RCTs were included. UAI reduced pain incidence within the first 24 h (RR 0.50, 95% CI 0.35-0.71, 308 teeth) and microbial counts (SMDpooled - 0.40, 95% CI [- 0.78, - 0.02], I2 = 0%, 126 teeth) than SI in non-vital teeth with apical periodontitis (AP). Both groups, however, had similar effects regarding pain intensity, lipopolysaccharide amounts, and the incidence of rescue-analgesic intake, treatment failure, and microbial presence (p > 0.05). CoE ranged from low to very low. Very limited evidence suggests that UAI could reduce postoperative-pain risk within the first 24 h and microbial counts for non-vital teeth with AP compared to SI. Most meta-analyses, however, are based on very few studies, mostly low-powered, with an overall very-low-to-low CoE. Further well-designed, larger RCTs are, thus, required.

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.

Abstract
This study aimed to evaluate the accuracy of back propagation (BP) artificial neural network model for predicting postoperative pain following root canal treatment (RCT). The BP neural network model was developed using MATLAB 7.0 neural network toolbox, and the functional projective relationship was established between the 13 parameters (including the personal, inflammatory reaction, operative procedure factors) and postoperative pain of the patient after RCT. This neural network model was trained and tested based on data from 300 patients who underwent RCT. Among these cases, 210, 45 and 45 were allocated as the training, data validation and test samples, respectively, to assess the accuracy of prediction. In this present study, the accuracy of this BP neural network model was 95.60% for the prediction of postoperative pain following RCT. To conclude, the BP network model could be used to predict postoperative pain following RCT and showed clinical feasibility and application value.

Abstract
INTRODUCTION The aim of present study was to evaluate the influence of apical limit of instrumentation and PDT on the postoperative pain of lower molars with asymptomatic apical periodontitis. METHODS Forty patients were included in the present study and were divided into 4 groups (n=10), according to apical limit of instrumentation and use of PDT: instrumentation at 0.0 measurement; instrumentation at 0.0 measurement+PDT; instrumentation 1mm beyond 0.0 measurement; instrumentation 1mm beyond 0.0 measurement+PDT. In the PDT, the root canals were filled with 0.01% methylene blue, remaining for 5 min. The low-intensity laser was used with 100 mW, 660-690 nm wavelength), using intra-canal fibre. Root canals were irradiated for 90 s, delivering total dose of 9 J and energy density of 320 J/cm2. After root canal preparation and PDT protocols, root canals were filled with gutta-percha and AH Plus endodontic sealer, being sealed with composite resin.The evaluation of postoperative pain was performed by visual analog scale after 24, 48, 72 hours and 7 days. Data were analysed by specific statistical tests, at level of 5%. RESULTS No statistical significant difference was observed among experimental groups in all evaluation periods, as well as in the intragroup analysis over time, regarding postoperative pain and analgesic medication consumption (p>0.05). CONCLUSIONS Apical limit of instrumentation and PDT have no influence on the postoperative pain of lower molars with asymptomatic apical periodontitis.

Abstract
INTRODUCTION Thorough pain assessment and thermal and mechanical testing are the primary diagnostic tools used to assess the status of pulp and periapical tissues in teeth with potential endodontic pathology. This study evaluated predictors of acute odontogenic pain to better understand the relationship between endodontic pain, clinical testing, endodontic disease, and diagnoses. METHODS Participants (N = 228) presenting with acute odontogenic pain underwent standardized clinical testing and reported their pain intensity. Univariate and multiple regression analyses were performed to evaluate the predictors of acute endodontic pain. Chi-square tests with Bonferroni adjustments were conducted to measure the frequency of endodontic diagnostic test findings and clinical observations in patients with different pulpal diagnoses. RESULTS A negative response to cold stimulation on the causative tooth and percussion hypersensitivity on the healthy adjacent tooth were the strongest predictors of higher levels of acute endodontic pain. Percussion hypersensitivity on the healthy adjacent tooth was present in a quarter of the cohort and was reported with equal frequency in teeth diagnosed with irreversible pulpitis, necrotic pulp, and previously initiated/treated teeth. Although painful percussion on the causative tooth was more frequently reported in teeth diagnosed with necrotic pulp, painful palpation was more frequently reported on teeth diagnosed with previously initiated/treated teeth. CONCLUSIONS Percussion hypersensitivity on the healthy adjacent tooth may reveal a lowered pain threshold and heightened pain sensitization. It is also possible that the 2 commonly performed mechanical sensory tests, percussion and palpation hypersensitivity, may detect different aspects of endodontic pathophysiology and pain processing.

Abstract
BACKGROUND The concept of instrumentation beyond the apical foramen by small flexible file to prevent apical blockage is apical patency. However, this procedure might endow postoperative pain, thus to maintain apical patency or not is the matter of dilemma. Hence, the primary objective of this study was to compare postoperative pain between apical patency and non-patency groups and secondary objective was to evaluate the influence of number of visits, vitality of teeth, group of teeth and preoperative pain on post-operative pain. METHODS Preselected (n = 178) patients based on group of teeth and status of pulp were randomly divided into 2 groups, apical patency and non-patency which was further treated in either single or multiple visits. After exclusion, 160 patients were included. Each group (n = 80) was subdivided in single visit (n = 40) and multiple visits (n = 40), including vital (n = 20) and non-vital teeth (n = 20) and single-rooted (n = 10) and multiple-rooted teeth (n = 10). Apical patency was maintained with a size 10 K-file during conventional hand filing step-back shaping procedure. Intensity of pain was recorded before treatment and on days 1, 2, and 7 after treatment using Numerical Rating Scale (NRS-11). Statistical analysis was done using Mann-Whitney U test, Spearman correlation and Multiple linear regression analysis. RESULTS The primary outcome of this study showed statistically significant difference (p < 0.05) in postoperative pain scores between patency and non-patency groups with higher pain scores in patency group on 1st, 2nd and 7th day follow up. The secondary outcome showed postoperative pain in patency-maintained group was influenced by status of the pulp and preoperative pain only. Vital teeth of patency-maintained group treated in multiple visits showed statistically significant (p = 0.02) post-operative pain in day 1 follow up. Pre-operative pain showed positive correlation with postoperative pain with statistically significant difference. CONCLUSIONS Our study concluded that maintenance of apical patency increased postoperative pain. Evaluation of influence of number of visits, status of pulp, group of tooth and preoperative pain revealed status of pulp and preoperative pain as influencing factors for postoperative pain in patency group.

Abstract
Objectives
The current study aimed to assess the impact of factors such as age, gender, and the tooth type on postoperative endodontic pain in necrotic teeth with symptomatic periapical periodontitis and radiolucency dressed randomly with either calcium hydroxide or propolis paste.
Materials and Methods
The standard chemomechanical root canal preparation of 80 teeth was performed by the primary investigator. The intracanal medicaments were inserted by the secondary operator. Patients self-recorded their postoperative endodontic pain intensity with the help of visual analog scale at 4, 12, 24 (day 2), 48 (day 3), and 72 (day 4) hours. During analysis, patients (68/80) were grouped according to gender, age, and the tooth type.
Statistical Analysis
Mann–Whitney’s
U
test was applied for mean pain score comparison between genders and between tooth type. Kruskal–Wallis’ test was applied for mean pain score comparison between the age groups.
Results
No significant difference (
p
> 0.05) in pain scores was found between the age groups and between the tooth types. Males had significantly higher pain scores as compared with females at days 2 (
p
= 0.035), 3 (
p
= 0.023), and 4 (
p
= 0.020).
Conclusion
The results suggested that there was no impact of age and tooth types on postoperative endodontic pain.

Abstract
OBJECTIVE To evaluate the influence of low-level laser therapy (LLLT) on postoperative pain after endodontic treatment. METHODS The PICOS strategy was used to identify randomized clinical trials comparing low-level laser therapy and mock laser therapy to manage postoperative pain after endodontic treatment, retreatment, and endodontic surgery. An electronic search was performed in MEDLINE through PubMed, Web of Science, LILACS, Scopus and Cochrane Library, OpenGrey and Google Scholar. Quality assessment was performed using the Cochrane Collaboration's tool for assessing the risk of bias. The quality of evidence was rated on the basis of the GRADE approach. RESULTS Twelve studies were included in the qualitative synthesis. Within the 12 studies, 7 articles were classified as "low risk of bias," 4 studies were considered "unclear risk of bias" and 1 study was considered "high risk of bias." Six studies evaluated the postoperative pain after primary root canal treatment, two studies after root canal retreatment and four after periapical surgery. Most of the studies reported significantly less postoperative pain after LLLT in different time periods; two studies found no differences. The certainty of evidence was classified as low and very low to treatment / retreatment and endodontic surgery, respectively. CONCLUSIONS Based on the limited quality evidence, most of the included studies reported significantly less postoperative pain after LLLT. However, the lack of standardization in laser parameters, use of medications and the certainty of evidence classified as low and very low indicate the need for further studies.

Abstract
INTRODUCTION Examining the evolution of research parameters helps scientists to discover the well-developed and neglected aspects of knowledge. Pain after root canal treatment is a health problem affecting millions of patients. Research in this field has a meaningful impact on quality of lives. The aim of this study was to analyze the evolution of research on postoperative pain over the past 50 years. METHODS Electronic searches were performed in Scopus and MEDLINE databases to identify studies on pain after nonsurgical root canal treatments/retreatments. The full texts of eligible articles were reviewed to determine the study category and to extract and analyze the methodological variables. A series of statistical analyses were performed to determine the trend of publications based on the variable of interest over time. RESULTS Four hundred twenty-four articles were included. There was a positive trend for systematic reviews, studies with sample size <200, studies on single-visit treatment, and clinical trials on instrumentation and adjunct treatments (P < .05). There was a negative trend for the use of numeric rating scales, studies on multiple-visit treatments, clinical trials on medication/medicament, and studies on pain in maxillary incisors (P < .05). No trend was observed based on pulpal diagnosis or for studies with longer observation periods (>8 weeks) (P > .05). CONCLUSIONS A paradigm shift is needed toward clinical studies with larger sample sizes, longer observation periods, and more focus on pulpal diagnoses associated with higher rates of postoperative pain. There is a need to view postoperative pain as an important patient-centered outcome and to develop and disseminate standard reporting guidelines for future studies.

Abstract
The progression of caries in permanent molar teeth of young patients, frequently result in endodontic treatment. This randomized blinded clinical trial assessed the effect of two endodontic sealers (Sealer 26 and AH Plus) on the incidence of pain and apical repair after endodontic treatment of young molar teeth, and secondly identify factors associated with the outcomes. Endodontic treatment was performed by undergraduate students in molar teeth (n=69) of young patients (n=54) at the Endodontic and Restorative Public Extension Clinic Service. Protaper Next was used and the endodontic sealers were allocated which were restored with direct composite resin. Two primary clinical outcomes - apical repair and postoperative pain, were assessed after 12 and 24 months for blinded operators. Description of incidence rates and mixed-model regression using Generalized Estimation Equations (GEE). After 2 years 69 molar teeth of 54 patients were evaluated. No effect of the endodontic sealer was observed irrespective of period of evaluation. Apical repair incidences and asymptomatic teeth were, respectively, 90.5 and 89.3, 96.8 and 90.0% during 1 and 2 years of follow-up. Failed apical repair was associated with unsatisfactory pulpectomy (p=0.003) and periapical conditions (p=0.007) as well as their interaction (p=0.016). None of these independent variables was able to predict the occurrence of pain in both periods. Prognosis of apical repair is dependent on the initial conditions. Endodontic treatment of young molars associated with composite resin restorations performed by undergraduate students have satisfactory results after 2 years and was effective to prevent the risk of permanent teeth loss.

[PMID: 33186627 DOI: 10.1016/j.jdent.2020.103523] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 11/02/2020] [Accepted: 11/05/2020] [Indexed: 12/15/2022] Open
Abstract
OBJECTIVES For more than twenty years, dental practice-based research networks (D-PBRN) have helped to structure clinical research in private practice. They bring together practitioners working in several structures and may include a greater number of subjects. The aims of this study were thus to systematically explore the scientific production from dental private practices in general and to map and describe the D-PBRN activity worldwide. DATA SOURCES Two research procedures were carried out in parallel. The first was conducted as a scoping review to examine peer-reviewed literature indexed in the PubMed database and the second was performed on the World Wide Web to identify the main characteristics of the networks (location, scientific production…). STUDY SELECTION 368 publications were identified among which 202 were published by PBRN members and the others by private practitioners not affiliated to any network. 210 (57 % of the included articles) were produced in the USA. A higher number of diverse centers are involved in each study when it is conducted by a PBRN (59.06 ± 66.59 vs. 13.51 ± 31.58 for networks and independent teams, respectively; p < 0.01). 24 D-PBRN were identified, a majority being based in the USA and 8 in Europe. CONCLUSIONS Although dental practice-based research has grown over the years, the number of D-PBRN worldwide remains low. Even if it requires some investment to produce research in dental offices, this type of networks helps to fill the gap between private practice and research and to improve knowledge on oral health. RELEVANCE The mapping of all the dental PBRN together with the research topics studied throughout the world make the relevance of this article. The ways to improve practice-based research in dentistry are also discussed in the paper.

Sodium Hypochlorite Reduces Postoperative Discomfort and Painful Early Failure after Carious Exposure and Direct Pulp Capping-Initial Findings of a Randomized Controlled Trial. J Clin Med 2020; 9:E2408. [PMID: 32731401 PMCID: PMC7464668 DOI: 10.3390/jcm9082408] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 07/14/2020] [Accepted: 07/26/2020] [Indexed: 12/11/2022] Open
Abstract
In this randomized controlled single-center clinical trial on 96 adult patients with parallel experimental groups (n = 48), the effects of washing a dentin/pulp wound in non-symptomatic teeth with extremely deep caries and pulpal exposure were compared between a 2.5% sodium hypochlorite (NaOCl) solution and a chemically-inert physiological saline control solution. After the allocated wound lavage, the pulps were capped with a mineral trioxide aggregate, covered by a glass-ionomer/resin liner, and the teeth were immediately restored with a resin-bonded-composite. In this first report, the early events were analyzed: postoperative discomfort (on an NRS-11 scale) at day-3 and -7 after intervention, and the occurrence of unbearable pain causing patients to contact the principal investigator to perform a root canal treatment (pulpectomy) during the first three months. The NaOCl solution caused a highly significant reduction in post-operative discomfort (p = 0.0010 day 3; p = 0.0007 day 7) and early painful failures (p = 0.0008) compared with the control. These novel findings highlight the importance of infection control in teeth with extremely deep carious lesions. Based on these observations, the use of an NaOCl solution to wash the exposed dentin/pulp wound in the vital pulp treatment is highly recommended in order to reduce pain and early failure.

Postendodontic Pain after Pulpotomy or Root Canal Treatment in Mature Teeth with Carious Pulp Exposure: A Multicenter Randomized Controlled Trial. Pain Res Manag 2020; 2020:5853412. [PMID: 32676136 PMCID: PMC7345601 DOI: 10.1155/2020/5853412] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 04/13/2020] [Accepted: 05/06/2020] [Indexed: 12/21/2022]
Abstract
This equivalence, randomized, clinical trial aimed to compare the postoperative pain of root canal therapy (RCT) with pulpotomy with mineral trioxide aggregate (PMTA) or calcium-enriched mixture (PCEM) in permanent mature teeth. In seven academic centers, 550 cariously exposed pulps were included and randomly allocated into PMTA (n = 188), PCEM (n = 194), or RCT (n = 168) arms. Preoperative “Pain Intensity” (PI) on Numerical Rating Scale and postoperative PIs until day 7 were recorded. Patients' demographic and pre-/intra-/postoperative factors/conditions were recorded/analysed. The arms were homogeneous in terms of demographics. The mean preoperative PIs were similar (P=0.998), the mean sum PIs recorded during 10 postoperative intervals were comparable (P=0.939), and the trend/changes in pain relief were parallel (P=0.821) in all study arms. The incidences of preoperative moderate-severe pain in RCT, PMTA, and PCEM arms were 56.5%, 55.7%, and 56.7%, which after 24 hours considerably decreased to 13.1%, 10.6%, and 12.9%, respectively (P=0.578). The time span of endodontic procedures was statistically different; RCT = 69.73, PMTA = 35.37, and PCEM = 33.62 minutes (P < 0.001). Patients with greater preoperative pain, symptomatic apical periodontitis, or presence of PDL widening suffered more pain (P=0.002, 0.035, and 0.023, resp.); however, other pre-/intra-/postoperative factors/conditions were comparable. Pulpotomy with MTA/CEM and RCT demonstrate comparable and effective postoperative pain relief.

Post-treatment endodontic pain following occlusal reduction in mandibular posterior teeth with symptomatic irreversible pulpitis and sensitivity to percussion: a single-centre randomized controlled trial. Int Endod J 2020; 53:1170-1180. [PMID: 32418236 DOI: 10.1111/iej.13328] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2020] [Revised: 05/09/2020] [Accepted: 05/12/2020] [Indexed: 11/30/2022]
Abstract
AIM This randomized, prospective, controlled trial assessed the effect of occlusal reduction on post-treatment endodontic pain and medication intake following root canal treatment of mandibular posterior teeth with symptomatic irreversible pulpitis with sensitivity to percussion treated in two visits. METHODOLOGY Three hundred and eight patients were randomly assigned into two equal groups according to whether occlusal reduction was done or not (n = 154). For all patients, root canal treatment was carried out in two visits without intracanal medication. Patients assessed their pain using the 0-10 numerical rating scale (NRS) 6, 12, 24 and 48 h after the first visit (post-instrumentation) and 6 and 12 h following root canal filling (post-obturation). Patients, also, recorded their medication intake (sham or analgesic), post-instrumentation and post-obturation; patients initially received a sham capsule, but, if pain persisted, an analgesic was prescribed. Data were analysed using Mann-Whitney U-test, Friedman's test, Wilcoxon's rank test and chi-square (χ2 ) test. The relative risk (RR) and its 95% confidence interval (CI) were calculated for binary data. RESULTS Occlusal reduction was associated with lower pain intensity than no occlusal reduction at 12 and 24 h post-instrumentation (P < 0.05). Pain intensity significantly and gradually decreased with both groups at all post-instrumentation and post-obturation time-points compared to preoperative pain (P < 0.05). The RR of moderate-to-severe pain was 0.61 (95% CI: 0.41, 0.91) 12 h post-instrumentation, and the RR of pain incidence, regardless of its level, was 0.75 (95% CI: 0.61, 0.92) 24 h post-instrumentation. There was no significant difference in medication intake (sham or analgesic) between groups (P > 0.05). CONCLUSIONS Occlusal reduction was effective in reducing the intensity of postoperative pain 12 h and 24 h after root canal instrumentation in the first visit in patients with symptomatic irreversible pulpitis with sensitivity to percussion. Occlusal reduction lowered the risk of moderate-to-severe pain by about 40% 12 h post-instrumentation and the overall risk of pain by 25% 24 h post-instrumentation; yet, it did not affect medication intake.

Abstract
INTRODUCTION The aim of this prospective, randomized, double-blind clinical trial was to evaluate the effect of a preoperative, single, oral dose of diclofenac potassium (DFK) on postoperative pain and rescue analgesic intake in patients with symptomatic irreversible pulpitis in mandibular molars treated in 1 visit. METHODS Seventy emergency patients with moderate to severe preoperative pain randomly received either 50 mg DFK or placebo tablets 1 hour before starting endodontic treatment (n = 35 per group). Patients recorded their pain level 6, 12, 24, and 48 hours after treatment on a 170-mm Heft-Parker visual analog scale. The incidence of rescue analgesic intake was also recorded. Outcome data were statistically analyzed using Mann-Whitney U, Friedman, Wilcoxon signed rank, and chi-square tests. Binary logistic regression assessed the association of predisposing factors with postoperative pain. The significance level (α) was set at 0.05. RESULTS Of the 70 patients, 68 were analyzed (n = 34 per group). Both groups had similar baseline characteristics (P > .05). DFK showed significantly less pain incidence and intensity than the placebo at 48 hours only (P < .05). A significant decrease occurred from 24 to 48 hours with DFK (P < .05), which was not recorded with the placebo (P > .05). No difference in the incidence of rescue analgesic intake was reported between groups (P > .05). Food intake timing, sex, and rescue analgesic intake were associated with postoperative pain (P < .05). CONCLUSIONS Premedication by a single, oral dose of 50 mg DFK could be effective in reducing postendodontic pain at 48 hours after 1-visit endodontic treatment in mandibular molars with symptomatic irreversible pulpitis.

Abstract
The purpose of this investigation was to compare ibuprofen versus an ibuprofen/acetaminophen combination for postoperative pain control in a patient model specific to teeth diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis. One hundred and two patients presenting with moderate to severe pain from a maxillary or mandibular posterior tooth diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis were included. Following local anesthetic administration, complete endodontic cleaning and shaping was performed. Patients were randomly assigned to receive identically appearing tablets of ibuprofen 200 mg or a combination of ibuprofen 200 mg/acetaminophen 216.7 mg with instructions to take 3 tablets every 6 hours as needed for pain. Patients were also given a prescription for an escape medication to take if the study medications did not adequately control their pain. A 4-day diary was used to record pain ratings and medication use. Moderate to severe pain was experienced by 59-61% of the patients on postoperative day 1 and 50-57% of the patients on day 2, with the pain ratings decreasing over the next 2 days. There were no statistically significant differences between the 2 groups in postoperative pain, percussion pain, or medication use. There was no difference between ibuprofen and the combination of ibuprofen/acetaminophen in the reduction of postoperative pain following endodontic debridement in patients with symptomatic irreversible pulpitis and symptomatic apical periodontitis.

Abstract
One of the main objectives of root canal treatment is to alleviate the pain associated with irreversibly inflamed pulps. However, some patients may have moderate to severe pain following treatment. The aim of this study was to compare and assess the effect of ketorolac tromethamine on substance P expression in the pulp and periapical tissues when used as a root canal irrigant for single-visit root canal treatment in teeth with irreversible pulpitis. Thirty-six patients were randomly allotted to three irrigant groups - saline (n = 14), 3% sodium hypochlorite (n = 11) and ketorolac tromethamine (n = 11). Pulp blood samples (S1) were collected on gaining access to the pulp, and periapical blood samples (S2) were collected after root canal preparation. Quantification of substance P was done by ELISA test. The ketorolac tromethamine group had greater reduction in substance P expression (S2). Post-operative pain levels were not significantly influenced by the different root canal irrigants.

Abstract
AIM To evaluate the effect of cold and room-temperature normal saline as a final irrigation on post-endodontic pain and to compare the post-endodontic pain level between the different protocols. MATERIALS AND METHODS A randomized controlled trial was conducted on 105 patients who underwent RCT and were distributed blindly and randomly into three equal groups (n = 35): Group 1, Cryotherapy group; Group 2, Room- temperature normal saline group; and Group 3, Control group. The patients were asked to fill out the VAS questionnaire and register their post-endodontic pain at 6, 24, and 48 h. One-way analysis of variance (ANOVA) and was used to determine statistical difference (α = 0.05) among the groups. Tuckey's test was used to calculate P-value (α = 0.05) between two each group. RESULTS The highest post-endodontic pain was in Group 3. There was no significance difference between Group 1 and Group 2. CONCLUSION Final flushing of the canal with saline either cold or at room temperature was effective for post-endodontic pain control. This can be promising as an essential step in endodontic treatment to reduce post-endodontic pain. The room-temperature saline as final irrigation showed comparable results to intra-canal cryotherapy.

Abstract
Introduction: This double-blind, placebo-controlled, clinical trial aimed to investigate the analgesic efficacy of low-level laser therapy (LLLT) with two different locations, and their comparison, in postoperative endodontic pain (PEP) levels in molars diagnosed with symptomatic irreversible pulpitis. Methods: Seventy-five patients with a molar tooth, diagnosed with symptomatic irreversible pulpitis, were divided into three groups of placebo, buccal only irradiation (BI), and buccal and lingual irradiation (BLI), with 25 cases being in each group. The participants received similar single-visit nonsurgical endodontic treatments. Then, a sham laser was used in the control group instead of LLLT. Individuals in BI and BLI groups received 80-second irradiation on the buccal surface and 80-second irradiation on each of the buccal and lingual surfaces respectively. A laser with an 808 nm wavelength, power of 100 mW, and a fiber diameter of 600 μm was used. PEP was assessed using a 0-100 mm VAS 4, 8, 24, and 48 hours after the treatment. Results: BLI showed a significantly higher reduction of PEP compared to placebo in all time intervals of this study. BLI was significantly more effective than BI 8 hours after the treatment. However, intragroup differences between BLI and BI groups at other time intervals and between BI and placebo groups in all time intervals were not significant. The number of taken analgesics in the BLI group was significantly lower than the placebo group and was on a statistical borderline compared to the BI group. Conclusion: LLLT with BLI was an effective measure as a supplement to oral analgesics in the reduction of PEP compared to the placebo.

Abstract
The aim of this study was to assess the effectiveness of low-level laser therapy (LLLT) for pain management after root canal treatment or retreatment. An electronic search for randomized controlled trials was conducted prior to November 2018, through PubMed, EMBASE, the Cochrane library (CENTRAL), and Web of Science. After filtering, seven articles were included, five related to root canal therapy (RCT) and two related to root canal retreatment (RCR). Six of the included studies presented a moderate risk of bias and a one low risk of bias, based on the Cochrane tool of risk of bias evaluation. The laser treatment included diode laser and indium-gallium-aluminum laser. LLLT was compared with placebo, blank, and ibuprofen treatment. Clinical outcome variables included the prevalence of pain, pain intensity, and need for analgesics after treatment. Three studies showed LLLT could reduce the prevalence of pain significantly after RCT or RCR. Although the effect of LLLT on pain intensity varied at different observation time points and among different studies, most of them found patients had lower pain intensity in the LLLT group. Of the three studies that assessed the need for analgesics after treatment, two studies showed significant benefits. Based on the current evidence, the use of LLLT for pain control in postendodontic therapy may be promising. However, solid conclusions should not be drawn definitely, given that more high-quality randomized controlled trials are required to further evaluate the efficacy of LLLT for pain management after RCT and RCR.

Abstract
OBJECTIVE The aim of this study is to evaluate the effect of intracanal cryotherapy on the fracture resistance of endodontically treated teeth. MATERIALS AND METHODS Sixty single-rooted maxillary lateral incisor teeth with single root canals were selected and randomly divided into two groups (n = 30). The specimens were immersed in distilled water, which was heated to 37 °C during the procedures. The root canals were chemomechanically prepared up to the apical size of 50 and assigned to either the control group or the cryotherapy group. The specimens in the cryotherapy group were irrigated with 20 mL sterile cold (2.5 °C) saline solution, which was delivered with an EndoVac system for 5 min, whereas the specimens in the control group received a sterile saline solution at room temperature. The fracture resistance of the specimens was then tested with a universal testing machine. The data was analyzed using the independent sample t test with a 5% significance threshold. RESULTS The fracture strength of the specimens in the intracanal cryotherapy group was significantly lower than that of the control group (p< .05). CONCLUSIONS Application of intracanal cryotherapy as a final irrigant reduced the vertical fracture resistance of prepared roots when compared to the control group.

IRANIAN ENDODONTIC JOURNAL 2019; 14:1-6. [PMID: 36879602 PMCID: PMC9984809 DOI: 10.22037/iej.v14i1.22815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Revised: 12/05/2018] [Indexed: 03/08/2023]
Abstract
Introduction After treating the tooth root canal, pain is one of the problems that many patients are facing. In order to reduce pain, and regarding the advice of treating necrotic teeth during several sessions, intra-canal medicaments can be used between sessions. The purpose of this study is to compare pain relieving effect of calcium hydroxide combined with three solutions of normal saline, chlorhexidine 2% and dexamethasone. Materials and methods This triple blind randomized clinical trial was performed on 90 necrotic molars and premolars. The patients were classified in three medicaments' groups including mixture of calcium hydroxide and normal saline (G1), chlorhexidine 2% (G2) or dexamethasone (G3) that were placed in the canal during the first treatment session. The patients were provided with a Heft-Parker Visual Analog Scale form to record their pain in different intervals of 4, 24, 48, 72 and 96 h after cleaning and shaping the root canal. Data analysis was carried out using the Chi-Square, one-way ANOVA and Repeated Measure tests. Results No significant difference was observed in the mean pain of the groups after 4 h (P>0.05). However, a significant difference was found between G1 and G3 in the mean pain from day 1 to 72 h after treatment. The mean pain was less in dexamethasone (G3) group (P<0.05), but the difference was not statistically significant at 96 h after treatment (P>0.05). No significant difference was found between "G2-G1" and "G2-G3" groups at different time intervals (P>0.05). Conclusion The mixture of calcium hydroxide and dexamethasone compared to calcium hydroxide and normal saline in short and medium time had a significant effect on reducing pain after cleaning and shaping the root canal. It seems that the mixture of calcium hydroxide and dexamethasone can be considered as an effective medicament on reducing pain during root canal treatment sessions.
