McGillivray A, Dutta A. The influence of laser-activated irrigation on post-operative pain following root canal treatment: A systematic review. J Dent 2024; 144:104928. [PMID: 38484867 DOI: 10.1016/j.jdent.2024.104928] [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: 01/15/2024] [Revised: 02/29/2024] [Accepted: 03/05/2024] [Indexed: 03/23/2024] Open
Abstract
OBJECTIVES Synthesise evidence on post-endodontic pain (PEP) in adult teeth undergoing primary root canal treatment with the adjunctive use of laser-activated irrigation (LAI) as compared with conventional needle irrigation (CNI) during the first post-operative week. DATA An electronic search was performed; no language constraints or restriction on the year of publication were applied. SOURCES Medline, Scopus, Cochrane and PubMed on 04 June 2023 STUDY SELECTION: Randomised clinical trials (RaCTs) that evaluated PEP after LAI of endodontic irrgants were included. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used. PEP was analysed at various time intervals until 1 week after treatment, related to the type of LAI used and the need for analgesia. REULTS Of the 793 articles identified through the electronic database search, 6 RaCTs were included. Qualitative review was favoured over meta-analysis due to substantial methodological heterogeneity between studies. Five studies were at high risk for bias determined by the Cochrane Risk-of-Bias 2 tool. Diode LAI demonstrated superior efficacy to needle irrigation in reducing pain 6-48 h post-treatment. The impact of LAI by photon-induced photoacoustic streaming (PIPS) was unclear and no difference was observed between PIPS and needle irrigation. However, PIPS mitigated PEP better than manual dynamic activation, sonic and ultrasonic activation. There was no difference in analgesia intake between LAI and needle irrigation groups. CONCLUSIONS LAI may help reduce PEP in the first 48 h. Methodological standardisation of future RaCTs on LAI would be beneficial in allowing a more accurate review with the possibility of quantitative synthesis. CLINICAL SIGNIFICANCE This unique synthesis used stringent criteria to reduce confounding factors and provided valuable evidence regarding PEP with different types of LAI. It helps clinicians choose an appropriate LAI technique as compared with CNI and predicts a time frame for reducing PEP.

Opioid versus opioid-free analgesia after surgical discharge: a systematic review and meta-analysis of randomised trials. Lancet 2022; 399:2280-2293. [PMID: 35717988 DOI: 10.1016/s0140-6736(22)00582-7] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Revised: 03/12/2022] [Accepted: 03/18/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Excessive opioid prescribing after surgery has contributed to the current opioid crisis; however, the value of prescribing opioids at surgical discharge remains uncertain. We aimed to estimate the extent to which opioid prescribing after discharge affects self-reported pain intensity and adverse events in comparison with an opioid-free analgesic regimen. METHODS In this systematic review and meta-analysis, we searched MEDLINE, Embase, the Cochrane Library, Scopus, AMED, Biosis, and CINAHL from Jan 1, 1990, until July 8, 2021. We included multidose randomised controlled trials comparing opioid versus opioid-free analgesia in patients aged 15 years or older, discharged after undergoing a surgical procedure according to the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity definition (minor, moderate, major, and major complex). We screened articles, extracted data, and assessed risk of bias (Cochrane's risk-of-bias tool for randomised trials) in duplicate. The primary outcomes of interest were self-reported pain intensity on day 1 after discharge (standardised to 0-10 cm visual analogue scale) and vomiting up to 30 days. Pain intensity at further timepoints, pain interference, other adverse events, risk of dissatisfaction, and health-care reutilisation were also assessed. We did random-effects meta-analyses and appraised evidence certainty using the Grading of Recommendations, Assessment, Development, and Evaluations scoring system. The review was registered with PROSPERO (ID CRD42020153050). FINDINGS 47 trials (n=6607 patients) were included. 30 (64%) trials involved elective minor procedures (63% dental procedures) and 17 (36%) trials involved procedures of moderate extent (47% orthopaedic and 29% general surgery procedures). Compared with opioid-free analgesia, opioid prescribing did not reduce pain on the first day after discharge (weighted mean difference 0·01cm, 95% CI -0·26 to 0·27; moderate certainty) or at other postoperative timepoints (moderate-to-very-low certainty). Opioid prescribing was associated with increased risk of vomiting (relative risk 4·50, 95% CI 1·93 to 10·51; high certainty) and other adverse events, including nausea, constipation, dizziness, and drowsiness (high-to-moderate certainty). Opioids did not affect other outcomes. INTERPRETATION Findings from this meta-analysis support that opioid prescribing at surgical discharge does not reduce pain intensity but does increase adverse events. Evidence relied on trials focused on elective surgeries of minor and moderate extent, suggesting that clinicians can consider prescribing opioid-free analgesia in these surgical settings. Data were largely derived from low-quality trials, and none involved patients having major or major-complex procedures. Given these limitations, there is a great need to advance the quality and scope of research in this field. FUNDING The Canadian Institutes of Health Research.

Evid Based Dent 2022:10.1038/s41432-021-0205-z. [PMID: 35165442 DOI: 10.1038/s41432-021-0205-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 05/14/2021] [Indexed: 06/14/2023]
Abstract
Aim Antibiotics are widely used to prevent flare-ups after endodontic treatment of non-vital teeth. This systematic review assessed the effect of antibiotic administration on post-endodontic treatment pain and flare-up rate.Methods Five major databases including Web of Science, Cochrane Library, PubMed, Scopus and Embase were searched to identify randomised clinical trials (RCTs) published until September 2020. Retrieved papers were critically appraised using the revised Cochrane risk of bias tool (RoB 2). To reduce the clinical heterogeneity, the included studies were divided into two groups: studies on symptomatic non-vital teeth and studies on asymptomatic non-vital teeth. The primary outcomes were 'post-operative pain' and 'flare-up rate'. The data of included studies were statistically combined through meta-analysis using random-effect model. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence.Results Six RCTs involving two RCTs (N = 61) on symptomatic teeth and four RCTs (N = 310) on asymptomatic teeth were included. In two RCTs on asymptomatic teeth, prophylactic antibiotic had been used, while in the remaining two RCTs, antibiotics had been administered after treatment. Quantitative synthesis of the RCTs showed that antibiotic administration following endodontic treatment of symptomatic non-vital teeth has no effect on pain severity at 24 hours following treatment (weighted mean difference [WMD] = -0.03; 95% confidence interval [CI]: -0.53 to 0.47), and the use of antibiotics before endodontic treatment of asymptomatic non-vital teeth has no effect on flare-up rate (relative risk [RR] = 0.58; 95% CI: 0.22-1.54). The GRADE approach revealed that the overall quality of evidence on the topic is low.Conclusions The antibiotic administration following endodontic treatment of symptomatic non-vital teeth has no effect on pain severity at 24 hours following treatment. Also, prophylactic antibiotics are ineffective in reducing the flare-up rate following treatment of asymptomatic non-vital teeth. However, to evaluate the effect of post-treatment antibiotics on flare-up rate in asymptomatic non-vital teeth, more high-quality RCTs are needed.

Abstract
Background A pulpectomy is regarded as the choice modality of treatment for necrotic teeth. The use of hand files, though popular traditionally as a gold standard, may be challenging due to increased chairside time. Postoperative pain is one of the most common complications of pulpectomy and may be unpleasant for a child/pedodontist. Rotary files were found to reduce instrumentation time, reduce apical extrusion, and in turn reduce pain but there is a lack of studies in primary teeth particularly for pediatric and reciprocating file systems. The increased number of options available today makes it a dilemma for the operator to choose a suitable file system. Aim and objective The study aimed to evaluate and compare the instrumentation time, postoperative pain, and effect on child's behavior among three groups, i.e., hand K-flex files (group I), pediatric rotary files (group II), and reciprocating files (group III). Materials and methods A total of 75 primary molar teeth after meeting inclusion criteria were randomly allocated into three groups. During the procedure, step-wise instrumentation time was recorded using a stopwatch. The child's behavior pre- and postoperatively was assessed by an evaluator. The postoperative pain (up to 1 week) was assessed by a questionnaire. Results The mean age of children taken for the study was 6.03 ± 1.2 years with 46 males and 29 females. The mean biomechanical preparation time was observed to be significantly shorter in the pediatric rotary and reciprocating file groups vs hand K-flex files (p < 0.001**). The postoperative pain after 6 hours had a mean value of 0.88 + 0.9 for the hand K-flex file group which was significantly higher than both rotary file groups (p < 0.05*). The pre- and postoperative behavior revealed no significant difference. Conclusion The clinical performance of pediatric and reciprocating files was superior, but the choice of file system did not significantly alter behavior.

Effect of low-level laser therapy on postoperative pain after single-visit root canal retreatment of mandibular molars: A randomized controlled clinical trial. Int Endod J 2021; 54:2006-2015. [PMID: 34383325 DOI: 10.1111/iej.13608] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 08/06/2021] [Accepted: 08/10/2021] [Indexed: 01/20/2023]
Abstract
AIM To compare the effect of low-level laser therapy (LLLT) on postoperative pain after single-visit root canal retreatment on mandibular molars. METHODOLOGY This randomized controlled clinical trial included 36 patients referred to the Department of Endodontics, Islamic Azad University, Tehran, Iran. Healthy patients who required root canal retreatment on symptomatic first or second mandibular molars, with a PAI index score of 2 or 3, preoperative tooth and percussion pain of <56 mm on a 170-mm visual analogue scale (VAS) were included. After local anaesthesia using inferior alveolar nerve block followed by rubber dam isolation and access cavity preparation, the D RaCe retreatment system was used to remove the existing root filling material, and after canal negotiation and gaining patency, working length was determined with an apex locator. Further canal enlargement was carried out with size 35, 0.04 taper, and size 40, 0.04 taper RaCe rotary instruments and then canals were filled using laterally compacted gutta-percha points and AH Plus sealer. The patients were randomly assigned to treatment groups: In the LLLT group, a 980-nm diode laser set at 6.89 W/cm2 energy density, 0.5 W power, and a tip diameter of 10 mm were activated from the buccal side on the mesial and distal root apices for 15 s. In the sham group, the laser handpiece was placed inside the patient's mouth at the same location, but the laser was not activated. Then patients were instructed to record their postoperative pain levels at 4, 8, 12 and 24 h and 2, 3 and 7 days after treatment on separate VAS scales. For data analysis, the independent sample t and the Mann-Whitney U tests were used. Nominal variables were analysed by using the chi-square test. RESULTS In the LLLT group, the most intense pain was reported 24 and 48 h post-treatment [mean (SD) = 0.22 (0.54) for both], whereas in the sham group, the most intense pain level was observed 4 h post-treatment [mean (SD) = 0.78 (0.80)]. At the 4-h interval, pain intensity was significantly lower in the LLLT group (p = .016). CONCLUSIONS Low-level laser therapy reduced postoperative pain after single-visit root canal retreatment of mandibular molars only four hours following the procedure.

Abstract
It is of interest to evaluate a single dose of three different analgesics compared to placebo in patients with symptomatic irreversible pulpitis. 120 patients were enrolled with severe pain in this prospective clinical trial. Patients were randomly divided into four groups after shaping and cleaning of root canals. This includes placebo, piroxicam 20mg, acetaminophen 325mg with aceclofenac sodium 100mg and acetaminophen 650mg. Participants were given a questionnaire to note the pain scores at various time intervals (6 hrs, 12 hrs, and 24 hrs) along with the respective tablets in a concealed manner. Data thus collected was analyzed for statistical significance. The severity of pain decreased in all the three interventional groups compared to the control group (p <0.01) at 6 hours. Zerodol-P and dolonex showed better pain reduction in comparison to the placebo and dolo 650 group (p <0.05) at 12 and 24 hours. Data shows that both zerodol-P and dolonex groups had similar effects at all time intervals. Thus, a single dose of analgesic such as Zerodol-P and Dolonex following shaping and cleaning of root canals relieved pain at all time intervals of the treatment. However, Dolo 650 performed better during the initial 6hrs after completion of the shaping and cleaning of root canals compared to the placebo.

Effect of intracanal cryotherapy on postendodontic pain: a systematic review and meta-analysis of randomized controlled trials. J Dent Anesth Pain Med 2021; 21:15-27. [PMID: 33585681 PMCID: PMC7871184 DOI: 10.17245/jdapm.2021.21.1.15] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 01/11/2021] [Accepted: 01/13/2021] [Indexed: 12/28/2022] Open
Abstract
This systematic review aimed to qualitatively and quantitatively evaluate the effectiveness of cryotherapy in the reduction of postendodontic pain. The review question was, "What will be the success rate of cryotherapy technique among human patients with postendodontic pain?". The review protocol was framed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Six studies were included in the review, and quantification of five studies was performed through a meta-analysis. In the forest plot representation of the studies comparing the control and cryotherapy groups in terms of the success rate in the management of postendodontic pain, the combined risk ratio (RR) was 0.80 (95% CI: 0.56 to 1.13) with a P value of 0.20. Based on the quantitative analysis, it can be suggested that intracanal cryotherapy does not play a significant role in reducing postendodontic pain.

Abstract
OBJECTIVES The current systematic review and meta-analysis aimed to assess the efficacy of prophylactic oral antibiotics in the management of post-operative endodontic symptoms in adults with necrotic pulp. MATERIALS AND METHODS A systematic search up to April 2020 was performed to find all randomised controlled trials (RTCs) comparing oral antibiotics with placebo to manage post-endodontic symptoms. The outcome measures were post-operative pain, swelling and/or the combined pain and swelling at different follow-ups. Standardised mean differences (SMDs) and 95% confidence intervals (CIs) were estimated using random-effect inverse-variance method. Additional analysis was performed if heterogeneity existed (P < .05). RESULTS For post-endodontic pain, 8 RCTs (n = 690) were included. Antibiotic prescription had no significant effect on endodontic pain at 6 (SMD = -0.008, 95% CI -0.279 - 0.264, P = .95), 12 (SMD = -0.080, 95% CI -1.39 - 1.23, P = .90), 24 (SMD = -0.044, 95% CI -0.29 - 0.20, P = .72), 48 (SMD = 0.18, 95% CI -0.26 - 0.62, P = .42) and 72 h (SMD= -0.050, 95% CI -0.33 - 0.23, P = .723) post-operatively. For post-endodontic swelling, 4 RCTs (n = 149) were included. Antibiotic prescription had no significant effect on endodontic swelling at 24 (SMD = 0.29, 95% CI -0.72 - 1.32, P = .56), 48 (SMD = -0.23, 95% CI -0.98 - 0.51, P = .54) and 72 hours (SMD= -0.03, 95% CI -1.25 - 1.33, P = .96), post-operatively. For combined pain and swelling, no meta-analysis was performed. CONCLUSION The administration of prophylactic antibiotics to prevent post-operative endodontic symptoms is not supported by the current evidence.

Objective This systematic review aims to evaluate the effects of ibuprofen compared to other drugs on the risk and intensity of postoperative pain resulting from endodontic treatment in adult patients. Methods A systematic search was carried out through Medline databases (Pubmed, Scopus, Web of Science, Cochrane, Lilacs, and BBO). There was no restriction on the publication year or idiom. The gray literature was explored. The Periodicos Capes Theses Databases and ProQuest Dissertations were also searched, as well as the unpublished and ongoing trials registry and the IADR abstracts (1990-2016). Solely randomized clinical trials that compared the risk or intensity of pain resulting from endodontic treatment in adult patients were included in this systematic review. The risk of bias of the articles was evaluated using the Cochrane Collaboration's tool. A random-effect meta-analysis was conducted for ibuprofen versus placebo and ibuprofen versus other drugs at 6, 8, and 24 hours. The GRADE approach was used to assess the quality of the evidence. Results A total of 1132 studies were identified, and only seven meet the eligibility criteria. No difference between the groups was detected in any of the meta-analysis. An exception was observed when one study was removed from the meta-analysis of pain intensity at 24 hours for ibuprofen versus placebo, favoring ibuprofen (SMD -0.67; 95% CI -1.05 to -0.17). The quality of evidence in all meta-analyses was graded as low or very low. Conclusion Results of the present systematic review indicate that there is no clear evidence supporting that preoperative ibuprofen is better than other drugs in reducing the risk and intensity of postendodontic pain.

Abstract
INTRODUCTION The purpose of the study was to evaluate the effects of intracanal, intraoral, and extraoral cryotherapy on postoperative pain in molar teeth with symptomatic apical periodontitis. METHODS A total of 100 patients were randomly distributed into 4 groups: control (without cryotherapy application), intracanal cryotherapy application, intraoral cryotherapy application, and extraoral cryotherapy application. The postoperative pain of the patients was recorded at the first, third, fifth, and seventh days. The data were statistically analyzed by using linear regression, χ2, one-way analysis of variance, Tukey post hoc, and Kruskal-Wallis H tests (P = .05). RESULTS There were no statistically significant differences among the groups in terms of demographic data (P > .05). The preoperative pain levels and preoperative visual analogue scale (VAS) scores of pain on percussion were similar among the groups (P > .05). The linear regression analysis demonstrated that group variable had the most significant effect on postoperative pain at day 1 (P < .001) among the other variables (group, age, gender, tooth number, preoperative pain levels, and VAS scores of pain on percussion). When compared with the control group, all the cryotherapy groups exhibited less percussion pain and less postoperative pain at the first, third, fifth, and seventh days (P < .05). CONCLUSIONS Within the study limitations, all the cryotherapy applications (intracanal, intraoral, and extraoral) resulted in lower postoperative pain levels and lower VAS scores of pain on percussion versus those of the control group.

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
BACKGROUND Little is known about the differences of rotary multiple file endodontic therapy and single-file reciprocating endodontic treatment under routine care conditions in dental practice. This multicenter study was performed to compare the outcome of multiple-file (MF) and single-file (SF) systems for primary root canal treatment under conditions of general dental practice regarding reduction of pain with a visual analogue scale (VAS 100), improvement of oral-health-related quality of life (OHRQoL) with the german short version of the oral health impact profile (OHIP-G-14) and the speed of root canal preparation. MATERIALS AND METHODS Ten general dental practitioners (GDPs) participated in the study as practitioner-investigators (PI). In the first five-month period of the study, the GDPs treated patients with MF systems. After that, the GDPs treated the patients in the second five-month period with a SF system (WaveOne). The GDPs documented the clinical findings at the beginning and on completion of treatment. The patients documented their pain and OHRQoL before the beginning and before completion of treatment. RESULTS A total of 599 patients were included in the evaluation. 280 patients were in the MF group, 319 were in the SF WaveOne group. In terms of pain reduction and improvement in OHIP-G-14, the improvement in both study groups (MF and SF) was very similar based on univariate analysis methods. Pain reduction was 34.4 (SD 33.7) VAS (MF) vs. 35.0 (SD 35.4) VAS (SF) (p = 0.840) and the improvement in OHIP-G-14 score was 9.4 (SD 10.3) (MF) vs. 8.5 (SD 10.2) (SF) (p = 0.365). The treatment time per root canal was 238.9 s (SD 206.2 s) (MF) vs. 146.8 sec. (SD 452.8 sec) (SF) (p = 0.003). DISCUSSION Regarding improvement of endodontic pain and OHRQoL measure with OHIP-G-14, there were no statistical significant differences between the SF und the MF systems. WaveOne-prepared root canals significantly faster than MF systems.

Abstract
BACKGROUND Post-obturation pain is frustrating to both patients and dentists. Its incidence may change with the use of contemporary endodontic techniques. This randomised clinical trial aims to compare the incidence of post-obturation pain at one and seven days after single-visit and multiple-visit non-surgical endodontic treatments. METHODS Patients who required primary endodontic treatment in the two clinical trial centres in Hong Kong (HK) and in Beijing (PK) were recruited. Three HK dentists and three PK dentists performed endodontic treatments on 567 teeth using the same procedures and materials, either in a single visit or over multiple visits, using either core carrier or cold lateral condensation for obturation. RESULTS The attrition rate was 5.1%, and a total of 538 teeth were evaluated. Among these teeth, 232 (43%) were operated in HK, 275 (51%) were treated in a single visit, and 234 (43%) were treated using core carrier obturation. Logistic regression analysis showed that teeth with apical periodontitis (OR = 0.35, 95% CI = 0.21-0.57, p < 0.01) and less pre-operative pain (OR = 1.10, 95% CI = 1.03-1.18, p < 0.01) had lower incidences of post-obturation pain after one day. The incidences of post-obturation pain after one day for single-visit and multiple-visit treatments were 24.7% (68 of 275) and 33.5% (88 of 263), respectively (p = 0.50). The incidences of post-obturation pain after seven days for single-visit and multiple-visit treatments were 4.0% (11 of 275) and 5.3% (14 of 263), respectively (p = 0.47). CONCLUSIONS There was no significant difference in the incidences of post-obturation pain after one day and seven days with single-visit or multiple-visit endodontic treatments.

Abstract
INTRODUCTION Nonsteroidal anti-inflammatory drugs (NSAIDs) have a well-established analgesic efficacy for inflammatory pain. These drugs exert their effect by inhibiting the enzyme cyclooxygenase (COX) and are commonly used for the management of pain after endodontic treatment. There are 2 distinct isoforms of COX: COX-1, which is constitutively expressed, and COX-2, which is primarily induced by inflammation. Previous studies have shown that functional human genetic variants of the COX-2 gene may explain individual variations in acute pain. The present study extends this work by examining the potential contribution of the 2 COX isoforms to pain after endodontic treatment. METHODS Ninety-four patients treated by endodontic residents at the University of North Carolina School of Dentistry were enrolled into a prospective cohort study. Data on potential predictors of post-treatment pain were collected, and all patients submitted saliva samples for genetic analysis. Nonsurgical root canal therapy was performed, and participants recorded pain levels for 5 days after. RESULTS In this study, 63% of patients experienced at least mild pain after root canal therapy, and 24% experienced moderate to severe pain. The presence of pretreatment pain was correlated with higher post-treatment pain (P = .01). Elevated heart rate (P = .02) and higher diastolic blood pressure (P = .024) were also correlated with decreased post-treatment pain. Finally, we identified genetic variants in COX-2 (haplotype composed of rs2383515 G, rs5277 G, rs5275 T, and rs2206593 A) associated with post-treatment pain after endodontic treatment (P = .025). CONCLUSIONS Understanding the genetic basis of pain after endodontic treatment will advance its prevention and management.

Abstract
Some patients experience severe pain following root canal therapy (RCT) despite advancements in care. We sought to identify factors, which can be measured preoperatively, that predict this negative outcome so that future research may focus on preemptive steps to reduce postoperative pain intensity. Sixty-two practitioners (46 general dentists and 16 endodontists) who are members of the National Dental Practice-Based Research Network enrolled patients receiving RCT for this prospective observational study. Baseline data collected from patients and dentists were obtained before treatment. Severe postoperative pain was defined based on a rating of ≥7 on a scale from 0 (no pain) to 10 (pain as bad as can be) for the worst pain intensity experienced during the preceding week, and this was collected 1 wk after treatment. Multiple logistic regression analyses were used to develop and validate the model. A total of 708 patients were enrolled during a 6-m period. Pain intensity data were collected 1 wk postoperatively from 652 patients (92.1%), with 19.5% (n = 127) reporting severe pain. In multivariable modeling, baseline factors predicting severe postoperative pain included current pain intensity (odds ratio [OR], 1.15; 95% confidence interval [CI], 1.07 to 1.25; P = 0.0003), number of days in the past week that the subject was kept from their usual activities due to pain (OR, 1.32; 95% CI, 1.13 to 1.55; P = 0.0005), pain made worse by stress (OR, 2.55; 95% CI, 1.22 to 5.35; P = 0.0130), and a diagnosis of symptomatic apical periodontitis (OR, 1.63; 95% CI, 1.01 to 2.64; P = 0.0452). Among the factors that did not contribute to predicting severe postoperative pain were the dentist's specialty training, the patient's age and sex, the type of tooth, the presence of swelling, or other pulpal and apical endodontic diagnoses. Factors measured preoperatively were found to predict severe postoperative pain following RCT. Practitioners could use this information to better inform patients about RCT outcomes and possibly use different treatment strategies to manage their patients (Clinicaltrials.gov NCT01201681).

Abstract
OBJECTIVE This study evaluates the use of a preoperative single oral dose of dexamethasone for the prevention and control of postendodontic pain. STUDY DESIGN Forty-seven patients were randomly assigned to 2 groups: placebo and dexamethasone (4 mg). The medications were administered 1 hour before the start of endodontic treatment. Postoperative pain was assessed after 4, 12, 24, and 48 hours. RESULTS Dexamethasone resulted in a statistically significant reduction in postendodontic pain at 4 and 12 hours (P < .05). However, no statistical difference (P > .05) was observed at 24 and 48 hours (Mann-Whitney test). The placebo group exhibited higher rescue medication intake (P < .05; Student t test). No side effects were reported for any of the medications used. CONCLUSION Preoperative single oral dose of dexamethasone substantially reduced postendodontic pain. Further studies are needed to evaluate the applicability of these findings to other clinical conditions and drug regimens.

Abstract
BACKGROUND This is an updated version of the Cochrane review published in Issue 4, 1998. Combining drugs from different classes with different modes of action may offer opportunity to optimise efficacy and tolerability, using lower doses of each drug to achieve the same degree of pain relief. Previously we concluded that addition of codeine to paracetamol provided additional pain relief, but at expense of additional adverse events. New studies have been published since. This review sought to evaluate efficacy and safety of paracetamol plus codeine using current data, and compare findings with other analgesics evaluated similarly. OBJECTIVES Assess efficacy of single dose oral paracetamol plus codeine in acute postoperative pain, increase in efficacy due to the codeine component, and associated adverse events. SEARCH STRATEGY We searched CENTRAL, MEDLINE, EMBASE, the Oxford Pain Relief Database in October 2008 for this update. SELECTION CRITERIA Randomised, double-blind, placebo-controlled trials of paracetamol plus codeine, compared with placebo or the same dose of paracetamol alone, for relief of acute postoperative pain in adults. DATA COLLECTION AND ANALYSIS Two authors assessed trial quality and extracted data. The area under the "pain relief versus time" curve was used to derive proportion of participants with paracetamol plus codeine and placebo or paracetamol alone experiencing least 50% pain relief over four-to-six hours, using validated equations. Number-needed-to-treat-to-benefit (NNT) was calculated using 95% confidence intervals (CIs). Proportion of participants using rescue analgesia over a specified time period, and time to use of rescue analgesia, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected. MAIN RESULTS Twenty-six studies, with 2295 participants, were included comparing paracetamol plus codeine with placebo. Significant dose response was seen for the outcome of at least 50% pain relief over four-to-six hours, with NNTs of 2.2 (95% CI 1.8 to 2.9) for 800 to 1000 mg paracetamol plus 60 mg codeine, 3.9 (2.9 to 4.5) for 600 to 650 mg paracetamol plus 60 mg codeine, and 6.9 (4.8 to 12) for 300 mg paracetamol plus 30 mg codeine. Time to use of rescue medication was over four hours with paracetamol plus codeine and two hours with placebo. The NNT to prevent remedication was 5.6 (4.0 to 9.0) for 600 mg paracetamol plus 60 mg codeine over four to six hours. Adverse events increased of mainly mild to moderate severity with paracetamol plus codeine than placebo.Fourteen studies, with 926 participants, were included in the comparison of paracetamol plus codeine with the same dose of paracetamol alone. Addition of codeine increased proportion of participants achieving at least 50% pain relief over four-to-six hours by 10 to 15%, increased time to use of rescue medication by about one hour, and reduced proportion of participants needing rescue medication by about 15% (NNT to prevent remedication 6.9 (4.2 to 19). Adverse events were mainly mild to moderate in severity and incidence did not differ between groups. AUTHORS' CONCLUSIONS This update confirms previous findings that combining paracetamol with codeine provided clinically useful levels of pain relief in about 50% of patients with moderate to severe postoperative pain, compared with under 20% with placebo. New information for remedication shows that the combination extended the duration of analgesia by about one hour compared to treatment with the same dose of paracetamol alone. At higher doses, more participants experienced adequate pain relief, but the amount of information available for the 1000 mg paracetamol plus 60 mg codeine dose was small, and based on limited information.

Abstract
BACKGROUND This is an updated version of the original Cochrane review published in Issue 1, 2004 - this original review had been split from a previous title on 'Single dose paracetamol (acetaminophen) with and without codeine for postoperative pain'. The last version of this review concluded that paracetamol is an effective analgesic for postoperative pain, but additional trials have since been published. This review sought to evaluate the efficacy and safety of paracetamol using current data, and to compare the findings with other analgesics evaluated in the same way. OBJECTIVES To assess the efficacy of single dose oral paracetamol for the treatment of acute postoperative pain. SEARCH STRATEGY We searched The Cochrane Library, MEDLINE, EMBASE, the Oxford Pain Relief Database and reference lists of articles to update an existing version of the review in July 2008. SELECTION CRITERIA Randomised, double-blind, placebo-controlled clinical trials of paracetamol for acute postoperative pain in adults. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Area under the "pain relief versus time" curve was used to derive the proportion of participants with paracetamol or placebo experiencing at least 50% pain relief over four to six hours, using validated equations. Number-needed-to-treat-to-benefit (NNT) was calculated, with 95% confidence intervals (CI). The proportion of participants using rescue analgesia over a specified time period, and time to use, were sought as measures of duration of analgesia. Information on adverse events and withdrawals was also collected. MAIN RESULTS Fifty-one studies, with 5762 participants, were included: 3277 participants were treated with a single oral dose of paracetamol and 2425 with placebo. About half of participants treated with paracetamol at standard doses achieved at least 50% pain relief over four to six hours, compared with about 20% treated with placebo. NNTs for at least 50% pain relief over four to six hours following a single dose of paracetamol were as follows: 500 mg NNT 3.5 (2.7 to 4.8); 600 to 650 mg NNT 4.6 (3.9 to 5.5); 975 to 1000 mg NNT 3.6 (3.4 to 4.0). There was no dose response. Sensitivity analysis showed no significant effect of trial size or quality on this outcome.About half of participants needed additional analgesia over four to six hours, compared with about 70% with placebo. Five people would need to be treated with 1000 mg paracetamol, the most commonly used dose, to prevent one needing rescue medication over four to six hours, who would have needed it with placebo. Adverse event reporting was inconsistent and often incomplete. Reported adverse events were mainly mild and transient, and occurred at similar rates with 1000 mg paracetamol and placebo. No serious adverse events were reported. Withdrawals due to adverse events were uncommon and occurred in both paracetamol and placebo treatment arms. AUTHORS' CONCLUSIONS A single dose of paracetamol provides effective analgesia for about half of patients with acute postoperative pain, for a period of about four hours, and is associated with few, mainly mild, adverse events.

Abstract
Successful management of endodontic pain represents a continuing challenge. The purpose of this randomized, double-blind, placebo-controlled, parallel-group trial was to compare the pain reducing effect of oral preparations of meloxicam, piroxicam, and placebo in endodontic emergency patients. A total of 51 patients who presented to the Tehran University endodontic clinic and one private dental clinic were invited to participate. Patients were asked to evaluate their pretreatment pain with a visual-analog scale. After root canal therapy they were randomly assigned to one of three groups: meloxicam, piroxicam, or placebo. Each patient was sent home with a visual-analog scale to fill out at 8 and 24 h after completion of therapy. The results of this study showed no significant differences between efficacy of meloxicam, piroxicam, and placebo, but a significant effect of the time factor in reducing postoperative pain in all treatment groups was observed.

Abstract
BACKGROUND Paracetamol (acetaminophen) and non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for the relief of mild and moderate pain arising from headache, musculoskeletal conditions and dysmenorrhoea. A prior Cochrane systematic review concluded that paracetamol is also effective for postoperative pain, but additional trials have since been published. This review sought to evaluate the efficacy and safety of paracetamol using current data, and to compare the findings with other analgesics evaluated in the same way. OBJECTIVES To assess the efficacy of single dose oral paracetamol for the treatment of acute postoperative pain. SEARCH STRATEGY We searched the Cochrane Library (Issue 3, 2002), the trials register of the Cochrane Pain, Palliative and Supportive Care group (November 2002); MEDLINE (1966 to May 1996); PubMed (1996 to August 2001); EMBASE (1980 to 1996); the Oxford Pain Relief Database (1950 to 1994); and reference lists of articles in order to update an existing version of the review. SELECTION CRITERIA Randomised, double-blind, placebo-controlled clinical trials of paracetamol for acute postoperative pain in adults. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality and extracted data. The area under the 'pain relief versus time' curve was used to derive the proportion of patients with paracetamol or placebo experiencing least 50% pain relief over four to six hours using validated equations. The number-needed-to-treat (NNT) was calculated using 95% confidence intervals. Information on adverse effects was also collected. MAIN RESULTS Forty-seven reports that enrolled 4186 patients (2561 patients were treated with a single oral dose of paracetamol and 1625 with placebo) met the inclusion criteria and were included in the analyses. The NNTs for at least 50% pain relief over four to six hours following a single dose of paracetamol were as follows: 325 mg NNT 3.8 (2.2 to 13.3); 500 mg NNT 3.5 (2.7 to 4.8); 600/650 mg NNT 4.6 (3.9 to 5.5); 975/1000 mg NNT 3.8 (3.4 to 4.4); and 1500 mg NNT 3.7 (2.3 to 9.5). Sub-group analysis showed no significant differences between smaller and larger trials, or lower and higher quality trials. Drug-related study withdrawals were rarely reported. Studies reported a variable incidence of adverse effects that were generally mild and transient. There were no statistically significant differences in the frequency of reported adverse effects between paracetamol 975/1000 mg and placebo. REVIEWER'S CONCLUSIONS Single doses of paracetamol are effective analgesics for acute postoperative pain and give rise to few adverse effects.

Abstract
The non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely used classes of drugs for the management of acute and chronic pain in dentistry. Their therapeutic efficacy and toxicity are well-documented and provide evidence that NSAIDs generally provide an acceptable therapeutic ratio of pain relief with fewer adverse effects than the opioid-mild analgesic combination drugs that they have largely replaced for most dental applications. The great many studies done with the oral surgery model of acute pain indicate that a single dose of an NSAID is more effective than combinations of aspirin or acetaminophen plus an opioid, with fewer side-effects, thus making it preferable for ambulatory patients. The combination of an NSAID with an opioid generally results in marginal analgesic activity but with an increased incidence of side-effects, which limits its use to patients in whom the NSAID alone results in inadequate analgesia. The selective COX-2 inhibitors hold promise for clinical efficacy with less toxicity from chronic administration and may prove advantageous for the relief of chronic orofacial pain. The use of repeated doses of NSAIDs for chronic orofacial pain should be re-evaluated in light of a lack of documented efficacy and the potential for serious gastrointestinal and renal toxicity with repeated dosing.

Abstract
BACKGROUND Ibuprofen and diclofenac are two widely used non-steroidal anti-inflammatory (NSAID) analgesics. It is therefore important to know which drug should be recommended for postoperative pain relief. This review seeks to compare the relative efficacy of the two drugs, and also considers the issues of safety and cost. OBJECTIVES To assess the analgesic efficacy of ibuprofen and diclofenac in single oral doses for moderate to severe postoperative pain. SEARCH STRATEGY Randomised trials were identified by searching Medline (1966 to December 1996), Embase (1980 to January 1997), the Cochrane Library (Issue 3 1996), Biological Abstracts (January 1985 to December 1996) and the Oxford Pain Relief Database (1950 to 1994). Date of the most recent searches: July 1998. SELECTION CRITERIA The inclusion criteria used were: full journal publication, postoperative pain, postoperative oral administration, adult patients, baseline pain of moderate to severe intensity, double-blind design, and random allocation to treatment groups which compared either ibuprofen or diclofenac with placebo. DATA COLLECTION AND ANALYSIS Data were extracted by two independent reviewers, and trials were quality scored. Summed pain relief or pain intensity difference over four to six hours was extracted, and converted into dichotomous information yielding the number of patients with at least 50% pain relief. This was then used to calculate the relative benefit and the number-needed-to-treat (NNT) for one patient to achieve at least 50% pain relief. MAIN RESULTS Thirty-four trials compared ibuprofen and placebo (3,591 patients), six compared diclofenac with placebo (840 patients) and there were two direct comparisons of diclofenac 50 mg and ibuprofen 400 mg (130 patients). In postoperative pain the NNTs for ibuprofen 200 mg were 3.3 (95% confidence interval 2.8 to 4.0) compared with placebo, for ibuprofen 400 mg 2.7 (2.5 to 3.0), for ibuprofen 600 mg 2.4 (1.9 to 3.3), for diclofenac 50 mg 2.3 (2.0 to 2.7) and for diclofenac 100 mg 1.8 (1.5 to 2.1). Direct comparisons of diclofenac 50 mg with ibuprofen 400 mg showed no significant difference between the two. REVIEWER'S CONCLUSIONS Both drugs work well. Choosing between them is an issue of dose, safety and cost.

Abstract
BACKGROUND Patient surveys have shown that postoperative pain is often not managed well, and there is a need to assess the efficacy and safety of commonly used analgesics as newer treatments become available. Paracetamol (acetaminophen) is an important non-opiate analgesic, commonly prescribed, as well as being available for retail sale. This review seeks to examine the efficacy of paracetamol alone and in combination with codeine, and also considers adverse effects. OBJECTIVES To assess the analgesic efficacy and adverse effects of a single dose of oral paracetamol (acetaminophen) alone and in combination with codeine for moderate to severe postoperative pain. SEARCH STRATEGY Published trials were identified from: Medline (1966 to May 1996), Embase (1980 to 1996), Cochrane Library (Issue 2 1996) and the Oxford Pain Relief Database (1950 to 1994). Additional trials were identified from reference lists of retrieved studies. Date of most recent searches: July 1998. SELECTION CRITERIA Inclusion criteria were: full journal publication, postoperative pain, postoperative oral administration, adult patients, baseline pain of moderate to severe intensity, double-blind design, and random allocation to treatment groups which compared paracetamol with placebo or a combination of paracetamol and codeine with either placebo or the same dose of paracetamol alone. DATA COLLECTION AND ANALYSIS Data were extracted by two independent reviewers, and trials were quality scored. Summed pain intensity and pain relief data were extracted and converted into dichotomous information to yield the number of patients with at least 50% pain relief. This was used to calculate the relative benefit and number-needed-to-treat (NNT) for one patient to achieve at least 50% pain relief over 4 to 6 hours compared with placebo. Adverse effects were used to calculate relative risk and number-needed-to-harm (NNH). MAIN RESULTS We found 40 trials of paracetamol against placebo (4171 patients), 22 trials of paracetamol plus codeine against placebo (1407 patients) and 12 trials of paracetamol plus codeine against the same dose of paracetamol (794 patients). In postoperative pain paracetamol 1000 mg had an NNT of 4.6 (3.8-5.4) for at least 50% pain relief when compared with placebo, and paracetamol 600/650 mg had an NNT of 5.3 (4.1-7.2). Paracetamol 600/650 mg plus codeine 60 mg had an NNT of 3. 6 (2.9-4.5). Comparing paracetamol plus codeine 60 mg with the same dose of paracetamol alone gave an NNT of 7.7 (5.1-17) for at least 50% pain relief. Adverse effects: Relative risk estimates for paracetamol 600/650 mg plus codeine 60 mg versus placebo showed a significant difference for 'drowsiness'/somnolence (NNH 11 (7.5- 0)) and dizziness (NNH 27 (15-164)) but no significant difference for nausea/vomiting. REVIEWER'S CONCLUSIONS Paracetamol is an effective analgesic with a low incidence of adverse effects. The addition of codeine 60 mg to paracetamol produces additional pain relief even in single oral doses, but may be accompanied by an increase in drowsiness and dizziness.

Abstract
The purpose of this study was to compare the pain-reducing efficacy of dexamethasone and ketorolac tromethamine when used as an intracanal medication, with oral ibuprofen and a placebo. An additional objective was to establish if any relationship exists between the incidence and severity of pretreatment pain and the incidence and severity of postinstrumentation pain. A total of 48 patients who presented to the University of Illinois postgraduate endodontic clinic were invited to participate. Patients were randomly assigned to 1 of 4 groups: oral ibuprofen, placebo, dexamethasone, or ketorolac tromethamine. Patients were asked to evaluate their pretreatment pain when they presented to the clinic with a Visual Analog Scale. The root canal treatment was performed in two appointments. The first appointment consisted of cleansing and shaping of the canal/s and placement of an intracanal medication. All teeth were closed with a sterile cotton pellet and IRM. Each patient was sent home with a Visual Analog Scale to fill out at 6, 12, 24 and 48 h after initiation of therapy. At the 12-h period, both dexamethasone and ketorolac provided statistically significant better pain relief than placebo. At the 24-h period, only ketorolac demonstrated better pain relief than the placebo. There were no statistically significant differences among the groups at 6 and 48 h. Although ibuprofen pain ratings were less than the placebo at all time points, the reduction was not significant. In addition, no significant differences were demonstrated between ibuprofen and either dexamethasone or ketorolac.

Abstract
Previous work has shown increased excitability of brainstem neurones in the trigeminal (V) subnucleus oralis following the deafferentation produced by tooth-pulp removal. The present study was designed to determine if the changes in oralis neuronal properties seen in cats 1-2 wk after the deafferentation could be blocked by local anaesthesia of the Vth nerve proximal to the sites of pulp injury just before the actual deafferentation. The response properties of neurones recorded in V subnucleus oralis were determined in anaesthetized cats. One or two weeks before neuronal recording, the pulps of the posterior mandibular teeth were removed under local mandibular anaesthesia in one group of cats (group A) and without local anaesthesia in a second group (group B); a third group (group C) had no pulp removal but received local anaesthesia. Consistent with the earlier data, there was a significantly increased incidence of neurones having an enlarged mechanoreceptive field, spontaneous activity and habituating tap sensitivity in group B compared to group C, but no significant differences were found between the two deafferented groups (A and B). As local anaesthesia did not prevent the development of pulp deafferentation-induced changes in the oralis neurones, it is unlikely that an afferent barrage of impulses induced by the deafferentation procedure was responsible for the neuroplastic changes that subsequently developed in the V subnucleus oralis.

Abstract
OBJECTIVES To assess whether adding codeine to paracetamol has an additive analgesic effect; to assess the safety of paracetamol-codeine combinations versus paracetamol alone. DESIGN Systematic literature review with meta-analysis, methodological quality of published trials being scored by means of 13 predefined criteria. TRIALS 24 of 29 trials that met the inclusion criteria. Models studied in the trials were postsurgical pain (21), postpartum pain (one), osteoarthritic pain (one), and experimentally induced pain (one). INTERVENTIONS Dosages ranged from 400 to 1000 mg paracetamol and 10 to 60 mg codeine. MAIN OUTCOME MEASURES The sum pain intensity difference (efficacy analysis) and the proportion of patients reporting a side effect (safety analysis). RESULTS Most trials were considered of good to very good quality. Only the single dose studies could be combined for analysis of analgesic efficacy. Pooled efficacy results indicated that codeine added to paracetamol provided a 5% increase in analgesia on the sum pain intensity difference. This effect was comparable to the difference in analgesic effect between codeine and placebo. The cumulative incidence of side effects with each treatment was comparable in the single dose trials. In the multidose studies a significantly higher proportion of side effects occurred with paracetamol-codeine preparations. CONCLUSION The difference is analgesic effect between paracetamol-codeine combinations and paracetamol alone was small but statistically significant. In the multidose studies the proportion of patients reporting a side effect was significantly higher with paracetamol-codeine combinations. For occasional pain relief a paracetamol-codeine combination might be appropriate but repeated use increases the occurrence of side effects.

Abstract
PROBLEM Antibiotics are often prescribed indiscriminately to treat endodontic emergencies. OBJECTIVES This study examined (1) the effect of penicillin supplementation on reduction of symptoms and (2) the course of recovery of localized acute apical abscess after emergency treatment. STUDY DESIGN Patients with pulp necrosis and periapical pain and/or localized swelling were considered. Those eligible did not have any signs of spreading infections. Patients received appropriate local treatment, and a double-blind protocol was used to randomly assign them to one of three groups: penicillin VK group, placebo group, or neither medication group. All received ibuprofen 600 mg four times daily for 24 hours. Patients entered their pre- and postoperative pain and swelling experience on a visual analog scale for up to 72 hours. RESULTS Resolution was fairly rapid in most patients. Statistical analysis of the scores of 32 respondents revealed no significant differences (at p < 0.05) between the three groups in course of recovery or symptoms at any time period. CONCLUSIONS Patients with localized periapical pain or swelling generally recovered quickly with local treatment. The data did not show a demonstrable benefit from penicillin supplementation.
