Etodolac versus dexamethasone effect in reduction of postoperative symptoms following surgical endodontic treatment: a double-blind study

Systemic Corticosteroid Uses in Endodontics-Part 1: Managing Postoperative Pain

INTRODUCTION

This study aimed to systematically search and review all available literature regarding systemic (oral or locally injected) corticosteroids in endodontics to assess their effect on postoperative pain.

METHODS

A search was conducted using PubMed, Cochrane Library, Embase, Scopus, Dentistry & Oral Science, and ProQuest. Randomized controlled trials enrolling participants undergoing endodontic treatment and assessing the presence of pain and pain scores at 6, 12, and 24 hours postoperatively were included. We synthesize the effect measures using risk ratios (RRs), standardized mean differences (SMDs), and their corresponding 95% confidence intervals (CIs). Meta-analysis was performed using the random-effects inverse variance method. The level of significance was set at P < .05. The certainty of the evidence was evaluated using Grading of Recommendations, Assessment, Development and Evaluation approach.

RESULTS

A total of 2303 participants from 29 trials were included. Patients who received corticosteroids were significantly less likely to report pain at 6 hours (RR = 2.5; 95% CI, 1.74-3.61; P < .00001), 12 hours (RR = 2.10; 95% CI, 1.53-2.90; P < .00001), and 24 hours (RR = 1.77; 95% CI, 1.38-2.28; P < .00001) postoperatively. Furthermore, they reported lower pain intensity at 6 hours (SMD = - 0.82; 95% CI, -1.17 to -0.48; P < .00001), 12 hours (SMD = - 0.63; 95% CI, -0.75 to -0.51; P < .00001), and 24 hours (SMD = - 0.68; 95% CI, -0.90 to -0.46; P < .00001) postoperatively.

CONCLUSIONS

Moderate certainty evidence indicates that the use of systemic corticosteroids likely results in a moderate to large reduction in postoperative endodontic pain.

Systemic antibiotics for symptomatic apical periodontitis and acute apical abscess in adults

BACKGROUND

Dental pain can have a detrimental effect on quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for these conditions should be removal of the source of inflammation or infection by local operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists frequently prescribe antibiotics in the absence of these signs. There is concern that this could contribute to the development of antibiotic-resistant bacteria. This review is the second update of the original version first published in 2014.

OBJECTIVES

To evaluate the effects of systemic antibiotics provided with or without surgical intervention (such as extraction, incision and drainage of a swelling, or endodontic treatment), with or without analgesics, for symptomatic apical periodontitis and acute apical abscess in adults.

SEARCH METHODS

We searched Cochrane Oral Health's Trials Register (26 February 2018 (discontinued)), CENTRAL (2022, Issue 10), MEDLINE Ovid (23 November 2022), Embase Ovid (23 November 2022), CINAHL EBSCO (25 November 2022) and two trials registries, and performed a grey literature search. There were no restrictions on language or date of publication.

SELECTION CRITERIA

Randomised controlled trials of systemic antibiotics in adults with a clinical diagnosis of symptomatic apical periodontitis or acute apical abscess, with or without surgical intervention (considered in this situation to be extraction, incision and drainage, or endodontic treatment) and with or without analgesics.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the results of the searches against inclusion criteria, extracted data and assessed risk of bias. We used a fixed-effect model in the meta-analysis as there were fewer than four studies. We contacted study authors to request missing information. We used GRADE criteria to assess the certainty of the evidence.

MAIN RESULTS

There was one new completed trial on this topic since the last update in 2018. In total, we included three trials with 134 participants. Systemic antibiotics versus placebo with surgical intervention and analgesics for symptomatic apical periodontitis or acute apical abscess One trial (72 participants) compared the effects of a single preoperative dose of clindamycin versus a matched placebo when provided with a surgical intervention (endodontic chemo-mechanical debridement and filling) and analgesics to adults with symptomatic apical periodontitis. We assessed this study at low risk of bias. There were no differences in participant-reported pain or swelling across trial arms at any time point assessed. The median values for pain (numerical rating scale 0 to 10) were 3.0 in both groups at 24 hours (P = 0.219); 1.0 in the antibiotic group versus 2.0 in the control group at 48 hours (P = 0.242); and 0 in both groups at 72 hours and seven days (P = 0.116 and 0.673, respectively). The risk ratio of swelling when comparing preoperative antibiotic to placebo was 0.50 (95% confidence interval (CI) 0.10 to 2.56; P = 0.41). The certainty of evidence for all outcomes in this comparison was low. Two trials (62 participants) compared the effects of a seven-day course of oral phenoxymethylpenicillin (penicillin VK) versus a matched placebo when provided with a surgical intervention (total or partial endodontic chemo-mechanical debridement) and analgesics to adults with acute apical abscess or symptomatic necrotic tooth. Participants in both trials also received oral analgesics. We assessed one study at high risk of bias and the other at unclear risk of bias. There were no differences in participant-reported pain or swelling at any time point assessed. The mean difference for pain (short ordinal numerical scale 0 to 3, where 0 was no pain) was -0.03 (95% CI -0.53 to 0.47) at 24 hours; 0.32 (95% CI -0.22 to 0.86) at 48 hours; and 0.08 (95% CI -0.38 to 0.54) at 72 hours. The standardised mean difference for swelling was 0.27 (95% CI -0.23 to 0.78) at 24 hours; 0.04 (95% CI -0.47 to 0.55) at 48 hours; and 0.02 (95% CI -0.49 to 0.52) at 72 hours. The certainty of evidence for all the outcomes in this comparison was very low. Adverse effects, as reported in two studies, were diarrhoea (one participant in the placebo group), fatigue and reduced energy postoperatively (one participant in the antibiotic group) and dizziness preoperatively (one participant in the antibiotic group). Systemic antibiotics without surgical intervention for adults with symptomatic apical periodontitis or acute apical abscess We found no studies that compared the effects of systemic antibiotics with a matched placebo delivered without a surgical intervention for symptomatic apical periodontitis or acute apical abscess in adults.

AUTHORS' CONCLUSIONS

The evidence suggests that preoperative clindamycin for adults with symptomatic apical periodontitis results in little to no difference in participant-reported pain or swelling at any of the time points included in this review when provided with chemo-mechanical endodontic debridement and filling under local anaesthesia. The evidence is very uncertain about the effect of postoperative phenoxymethylpenicillin for adults with localised apical abscess or a symptomatic necrotic tooth when provided with chemo-mechanical debridement and oral analgesics. We found no studies which compared the effects of systemic antibiotics with a matched placebo delivered without a surgical intervention for symptomatic apical periodontitis or acute apical abscess in adults.

Pain in Oral and Maxillofacial Surgery and Implant Dentistry: Types and Management

Over the years, the pain has been defined numerous times in several ways. In oral and maxillofacial surgery, the occurrence of pain, especially postoperatively, is anticipated. Pain arises as a combination of various processes after tissue damage. Distinct pain experiences in oral surgery were depicted in several previous studies, adding knowledge to the field. The management of these encounters has been suggested over time, improving treatment approaches in the clinical setting. This review aims to understand the pain and its types and intervention in the field of oral and maxillofacial surgery.

Management of patients receiving novel antithrombotic treatment in endodontic practice: Review and clinical recommendations

Cardiovascular diseases are a major component of non-communicable diseases and death, with thrombosis constituting the most common underlying pathosis of the three major cardiovascular disorders: ischaemic heart disease (acute coronary syndrome), stroke and venous thromboembolism (VTE). The introduction of direct oral anticoagulants (DOACs) in recent years has necessitated a more complex approach to periprocedural and perioperative anticoagulation management and the need for revised management strategies and protocols. Currently, patients taking classic oral anticoagulants are advised to stop taking the drugs and have their INR values checked 72 h prior to dental surgery (e.g., apical surgery, tooth extraction, and periodontal surgery) and checked again 24 h prior to the procedure to ensure it is within the therapeutic range. However, the current incorporation of these novel DOACs in routine medical practice requires changes in the way patients are managed preoperatively in dentistry, and specifically in endodontic surgery. The methodology applied in this review included searching for relevant articles in the PubMed database using keywords listed in the Entree Terms databases. Articles published on human blood clotting mechanism, antithrombotic drugs, as well as treatment guidelines and recommendations for dentistry were retrieved. In addition, textbooks and guidelines that may not have surfaced in the online search were searched manually. The aim of this paper was to review the mechanisms of action of classic and novel antithrombotic medications and their impact on endodontic treatment and the management of local haemostasis in endodontics.

Effect of periapical surgery on oral health-related quality of life in the first postoperative week using the Dutch version of Oral Health Impact Profile-14

Objective

To evaluate whether periapical surgery affects oral health-related quality of life (OHRQoL) within the first postoperative week.

Study design

The primary outcomes in 133 patients (54 men, 79 women; mean age 50.8 years) undergoing periapical surgery were the Oral Health Impact Profile-14 (OHIP-14) score and postoperative sequelae, including pain, analgesic intake, swelling, limited mouth opening, chewing difficulties, and postoperative infection.

Results

We found a significant effect on OHIP-14, pain, and analgesics, which decreased throughout the week. We found no significant differences in mean OHIP-14, pain scores, or analgesic use for gender, medical history, surgical flaps, operation time, or location of the operated teeth. Younger patients had a higher OHIP-14 score in the first 2 days after surgery and more pain on the first postoperative day. Women experienced more pain during the first 3 days. Smokers had a higher OHIP-14 score on the first postoperative day and greater pain during the first 3 days compared to non-smokers.

Conclusion

We identified a low incidence of pain and reduced OHRQoL following periapical surgery. The postoperative reduction in OHRQoL and pain were of short duration, with maximum intensity in the early postoperative period and rapidly decreasing with time.

Severe Pain after Endodontic Surgery: An Analysis of Incidence and Risk Factors

INTRODUCTION

The aim of this study was to determine the prevalence and characteristics of postoperative pain after endodontic microsurgery and to identify potential predictors for severe pain.

METHODS

One hundred seventy-three patients who underwent endodontic microsurgery at a private practice were included in the study. The patients were asked to fill out a questionnaire to assess their postoperative pain levels for 5 days after surgery. The questionnaires were analyzed to record the changes in pain levels over time. The presence and size of preoperative lesions and bone thickness were determined on preoperative cone-beam computed tomographic scans. Statistical analyses were performed to identify predictors for developing severe pain after surgery. A binary logistic regression model was established to predict the occurrence of severe pain.

RESULTS

Severe pain was most prevalent on day 1 (17.3%) and gradually decreased until a small increase on day 5. The average pain level also peaked on day 1 postoperatively and gradually decreased afterward. No significant difference was observed between patients who reported severe pain and those who did not report severe pain regarding tooth position (anterior vs posterior), lesion size, and presence of fenestration. However, sex, age, and bone thickness were all significant predictors of severe postoperative pain, with odds ratios of 2.8, 0.96, and 1.41, respectively.

CONCLUSIONS

Severe pain was reported only in a small number of patients after endodontic microsurgery. Younger patients, females, and patients with thicker bone covering the apex are significantly more likely to develop severe pain.

Combination of etodolac and dexamethasone improves preemptive analgesia in third molar surgery: a randomized study

OBJECTIVE

This randomized, controlled, triple-blind, crossover clinical trial aimed to investigate the use of dexamethasone (DEX) and etodolac (ETO) as preemptive analgesia before mandibular third molar extraction.

METHODS

Patients were divided into three groups (n = 20 teeth each) based on the drug administered: DEX 8 mg (DEX); DEX 8 mg plus ETO 300 mg (DEX + ETO), and ETO 300 mg (ETO). Paracetamol (750 mg) tablets were administered as rescue analgesics. Pain was evaluated using the visual analog scale (VAS) at 6, 12, 24, 48, and 72 h and 7 days postoperatively. Edema and trismus were assessed 48 and 72 h postoperatively. All data were subjected to statistical analysis, where a P value < .05 indicated statistical significance.

RESULTS

VAS scores and the number of rescue analgesics taken were lower in the DEX + ETO group than in the other groups (P < .001 and P = .014, respectively). At 48 h, trismus was similar among all groups; however, the ETO group showed the highest trismus 7 days postoperatively (P < .05). Edema was similar among all groups at all time points (P > .05).

CONCLUSION

The combined use of the anti-inflammatory drugs, DEX and ETO, resulted in better pain control and the need for fewer rescue analgesics than the use of either drug alone, which indicated their effectiveness in mandibular third molar extractions preoperatively.

CLINICAL RELEVANCE

This drug combination can lead to less pain, edema, and trismus and reduce the use of rescue analgesics in the postoperative period.

Effect of Pulpotomy Procedures With Mineral Trioxide Aggregate and Dexamethasone on Post-endodontic Pain in Patients with Irreversible Pulpitis: A Randomized Clinical Trial

Objective:

Endodontic post-treatment pain continues to be one of the main problems encountered by dental professionals. Therefore, pain control during and after endodontic treatment is one of the most important issues in endodontics. The purpose of this clinical trial was to compare postoperative pain relief achieved with dexamethasone (DEX) and mineral trioxide aggregate (MTA) used as pulp coverage after pulpotomy in human molars with irreversible pulpitis.

Methods:

This prospective double-blind study was conducted on 54 patients complaining of dental pain due to irreversible pulpitis. The standard pulpotomy procedure was performed by the same dentist in all patients. At the time of the cotton pellet placement, patients were randomly divided into three groups: those in whom a sterile dry cotton (DC) pellet was used, patients treated with a cotton pellet soaked in MTA, and those who were treated with a cotton pellet soaked in DEX. After completion of the treatment, patients received rescue medication every 6 hours for the first day. Postoperative pain was assessed at 6-hour intervals for 24 hours, and then every day until day 7 using a visual analog scale.

Results:

In general, patients treated with MTA suffered the lowest levels of pain at all time intervals. Post-pulpotomy pain was significantly reduced at 18 and 24 hours and from days 2 to 7 post-treatment in the MTA group. DEX lowered the pain level more than the DC pellet. However, the differences observed in the mean pain scores of the DEX and DC pellet groups at all-time intervals were not statistically significant.

Conclusion:

Pulpotomy procedures can reduce pain related irreversible pulpitis. Pulpotomy with MTA-soaked cotton pellet significantly reduces pain intensity in patients with irreversible pulpitis.

Effect of pretreatment medication on postendodontic pain: A double-blind, placebo-controlled study

BACKGROUND

Posttreatment endodontic pain has been reported in 25%-40% of all endodontic patients. Effective management of endodontic pain represents a continuing challenge.

AIM

To evaluate and compare the efficacy of preoperative single dose of nonsteroidal anti-inflammatory drug, piroxicam (20 mg), with two types of corticosteroid drugs - dexamethasone (4 mg) or deflazacort (30 mg) - for the prevention and control of postendodontic pain.

MATERIALS AND METHODS

A total of 132 volunteers selected for nonsurgical root canal therapy were randomly divided into the following four groups (n = 30 each) according to preoperative medication given: Group 1, piroxicam (20 mg); Group 2, dexamethasone (4 mg); Group 3, deflazacort (30 mg); and Group 4, placebo. The preoperative medications were administrated 1 h before the start of standard endodontic treatment. Patients were instructed to complete a pain diary using Visual Analog Scale preoperatively and at 6-, 12-, 24-, 48-, and 72-h intervals after root canal instrumentation.

STATISTICAL ANALYSIS

The correlation between preoperative endodontic pain to postoperative pain and pair-wise comparison of four groups was evaluated by Kruskal-Wallis analysis of variance test followed by Mann-Whitney U-test.

RESULTS

Compared to the placebo group, piroxicam, dexamethasone, and deflazacort resulted in a statistically significant reduction in postendodontic pain at 6, 12, and 24 h (P < 0.05).

CONCLUSION

Preoperative single oral dose of piroxicam or dexamethasone or deflazacort is equally effective in controlling postendodontic pain.

Systemic antibiotics for symptomatic apical periodontitis and acute apical abscess in adults

BACKGROUND

Dental pain can have a detrimental effect on quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for teeth with these conditions should be removal of the source of inflammation or infection by local, operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists frequently prescribe antibiotics in the absence of these signs. There is concern that this could contribute to the development of antibiotic-resistant bacterial colonies within both the individual and the community. This review is an update of the original version that was published in 2014.

OBJECTIVES

To evaluate the effects of systemic antibiotics provided with or without surgical intervention (such as extraction, incision and drainage of a swelling, or endodontic treatment), with or without analgesics, for symptomatic apical periodontitis and acute apical abscess in adults.

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 26 February 2018), the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 1) in the Cochrane Library (searched 26 February 2018), MEDLINE Ovid (1946 to 26 February 2018), Embase Ovid (1980 to 26 February 2018), and CINAHL EBSCO (1937 to 26 February 2018). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. A grey literature search was conducted using OpenGrey (to 26 February 2018) and ZETOC Conference Proceedings (1993 to 26 February 2018). No restrictions were placed on the language or date of publication when searching the electronic databases.

SELECTION CRITERIA

Randomised controlled trials of systemic antibiotics in adults with a clinical diagnosis of symptomatic apical periodontitis or acute apical abscess, with or without surgical intervention (considered in this situation to be extraction, incision and drainage or endodontic treatment) and with or without analgesics.

DATA COLLECTION AND ANALYSIS

Two authors screened the results of the searches against inclusion criteria, extracted data and assessed risk of bias independently and in duplicate. We calculated mean differences (MD) (standardised mean difference (SMD) when different scales were reported) and 95% confidence intervals (CI) for continuous data. A fixed-effect model was used in the meta-analysis as there were fewer than four studies. We contacted study authors to obtain missing information.

MAIN RESULTS

We included two trials in this review, with 62 participants included in the analyses. Both trials were conducted in university dental schools in the USA and compared the effects of oral penicillin V potassium (penicillin VK) versus a matched placebo when provided in conjunction with a surgical intervention (total or partial pulpectomy) and analgesics to adults with acute apical abscess or symptomatic necrotic tooth. The patients included in these trials had no signs of spreading infection or systemic involvement (fever, malaise). We assessed one study as having a high risk of bias and the other study as having unclear risk of bias.The primary outcome variables reported in both studies were participant-reported pain and swelling (one trial also reported participant-reported percussion pain). One study reported the type and number of analgesics taken by participants. One study recorded the incidence of postoperative endodontic flare-ups (people who returned with symptoms that necessitated further treatment). Adverse effects, as reported in one study, were diarrhoea (one participant, placebo group) and fatigue and reduced energy postoperatively (one participant, antibiotic group). Neither study reported quality of life measurements.Objective 1: systemic antibiotics versus placebo with surgical intervention and analgesics for symptomatic apical periodontitis or acute apical abscessTwo studies provided data for the comparison between systemic antibiotics (penicillin VK) and a matched placebo for adults with acute apical abscess or a symptomatic necrotic tooth when provided in conjunction with a surgical intervention. Participants in one study all underwent a total pulpectomy of the affected tooth, while participants in the other study had their tooth treated by either partial or total pulpectomy. Participants in both trials received oral analgesics. There were no statistically significant differences in participant-reported measures of pain or swelling at any of the time points assessed within the review. The MD for pain (short ordinal numerical scale 0 to 3) was -0.03 (95% CI -0.53 to 0.47) at 24 hours; 0.32 (95% CI -0.22 to 0.86) at 48 hours; and 0.08 (95% CI -0.38 to 0.54) at 72 hours. The SMD for swelling was 0.27 (95% CI -0.23 to 0.78) at 24 hours; 0.04 (95% CI -0.47 to 0.55) at 48 hours; and 0.02 (95% CI -0.49 to 0.52) at 72 hours. The body of evidence was assessed as at very low quality.Objective 2: systemic antibiotics without surgical intervention for adults with symptomatic apical periodontitis or acute apical abscessWe found no studies that compared the effects of systemic antibiotics with a matched placebo delivered without a surgical intervention for symptomatic apical periodontitis or acute apical abscess in adults.

AUTHORS' CONCLUSIONS

There is very low-quality evidence that is insufficient to determine the effects of systemic antibiotics on adults with symptomatic apical periodontitis or acute apical abscess.

Effect of Corticosteroids on Pain Relief Following Root Canal Treatment: A Systematic Review

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.

Effect of Dexamethasone Intraligamentary Injection on Post-Endodontic Pain in Patients with Symptomatic Irreversible Pulpitis: A Randomized Controlled Clinical Trial

Introduction:

The aim of this randomized-controlled clinical trial was to assess the effect of intraligamentary (PDL) injection of dexamethasone on onset and severity of post-treatment pain in patients with symptomatic irreversible pulpitis.

Methods and Materials:

A total number of 60 volunteers were included according to the inclusion criteria and were assigned to three groups (n=20). After administration of local anesthesia and before treatment, group 1 (control) PDL injection was done with syringe containing empty cartridge, while in groups 2 and 3 the PDL injection was done with 0.2 mL of 2% lidocaine or dexamethasone (8 mg/2 mL), respectively. Immediately after endodontic treatment patients were requested to mark their level of pain on a visual analogue scale (VAS) during the next 48 h (on 6, 12, 24 and 48-h intervals). They were also asked to mention whether analgesics were taken and its dosage. Considering the 0-170 markings on the VAS ruler, the level of pain was scored as follows: score 0 (mild pain; 0-56), score 1 (moderate pain; 57-113) and score 3 (severe pain; 114-170). The data were analyzed using the Kruskal-Wallis and the Chi-square tests and the level of significance was set at 0.05.

Results:

After 6 and 12 h, group 1 and group 3 had the highest and lowest pain values, respectively (P<0.01 and P<0.001 for 6 and 12 h, respectively). However, after 24 and 48 h the difference in the pain was not significant between groups 1 and 2 (P<0.6) but group 3 had lower pain levels (P<0.01 and P<0.8 for 24 and 48 h, respectively).

Conclusion:

Pretreatment PDL injection of dexamethasone can significantly reduce the post-treatment endodontic pain in patients with symptomatic irreversible pulpitis.

Comparison Between Dexamethasone and Ibuprofen for Postoperative Pain Prevention and Control After Surgical Implant Placement: A Double-Masked, Parallel-Group, Placebo-Controlled Randomized Clinical Trial

BACKGROUND

Postoperative pain is a potential adverse side effect of oral surgeries, and attempts should be made to prevent or minimize it. This study compares efficacy of preemptive ibuprofen and dexamethasone protocols for pain prevention or control after surgical implant placement.

METHODS

This prospective, double-masked, parallel-group, placebo-controlled, randomized clinical trial included 117 patients with planned dental implant placement. Patients were assigned to receive one of three different protocols: 1) 600 mg ibuprofen 1 hour before surgery and another 600 mg 6 hours after the first dose; 2) 4 mg dexamethasone 1 hour before surgery and another 4 mg 6 hours after the first dose; or 3) placebo. Rescue medication (1,000 mg acetaminophen) was made available to each patient, and they were instructed to take it as necessary. Pain intensity was evaluated via a 101-point numeric rating scale and a visual analog scale, and discomfort was evaluated using a four-point verbal rating scale hourly for the first 8 hours after surgery and three times daily for the following 3 days.

RESULTS

Ibuprofen and dexamethasone significantly reduced pain (Kruskal-Wallis; P <0.05) up to 3 days after surgery and discomfort (P <0.05) up to 2 days after surgery compared with placebo treatment. Both treatments reduced the number of painkillers taken and increased time before the first painkiller was taken (P <0.01).

CONCLUSION

Steroidal dexamethasone is as effective as non-steroidal ibuprofen for preventing or controlling postoperative pain and discomfort after surgical implant placement.

Comparative Assessment of the Effect of Ibuprofen and Etodolac on Edema, Trismus, and Pain in Lower Third Molar Surgery: A Randomized Clinical Trial

PURPOSE

To compare the efficacy of ibuprofen (IBU) and etodolac (ETO) for controlling pain, edema, and trismus after extraction of lower third molars.

MATERIALS AND METHODS

Twenty adolescents and adults with 2 impacted mandibular-third molars (in similar positions) were selected for the study. Patients were randomly assigned either to the IBU group (600 mg of IBU 3 times a day for 3 days) or to the ETO group (300 mg of ETO 3 times a day for 3 days). Drugs were administered immediately after dental extraction.

RESULTS

During the first 2 days after extraction, swelling was more pronounced in the IBU group than in the ETO group (P = .033). Seven days after surgery, there was no difference in the degree of edema between the groups. At the 2- and 7-day evaluation points, mouth opening was significantly more reduced in the IBU group than in the ETO group (P < .05). After the first 6 hours, the ETO group had more effective pain relief (P < .05), but after this time point, both groups reported similar degrees of relief. Compared with the IBU group, the ETO group had a lower need for administration of additional rescue analgesics.

CONCLUSIONS

After extraction of impacted lower third molars, we found that swelling, trismus, and pain were more effectively controlled with ETO than with IBU.

Systemic antibiotics for symptomatic apical periodontitis and acute apical abscess in adults

BACKGROUND

Dental pain can have a considerable detrimental effect on an individual's quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for teeth with symptomatic apical periodontitis or an acute apical abscess should be removal of the source of inflammation or infection by local, operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists continue to prescribe antibiotics for these conditions. There is concern that this could contribute to the development of antibiotic-resistant bacterial colonies both within the individual and within the community as a whole.

OBJECTIVES

To evaluate the effects of systemic antibiotics provided with or without surgical intervention (such as extraction, incision and drainage of a swelling or endodontic treatment), with or without analgesics, for symptomatic apical periodontitis or acute apical abscess in adults.

SEARCH METHODS

We searched the following electronic databases: Cochrane Oral Health Group's Trials Register (to 1 October 2013); Cochrane Central Register of Controlled Trials (The Cochrane Library 2013, Issue 9); MEDLINE via OVID (1946 to 1 October 2013); EMBASE via OVID (1980 to 1 October 2013) and CINAHL via EBSCO (1980 to 1 October 2013). We searched the World Health Organization (WHO) International Trials Registry Platform and the US National Institutes of Health Trials Registry (ClinicalTrials.gov) on 1 October 2013 to identify ongoing trials. We searched for grey literature using OpenGrey (to 1 October 2013) and ZETOC Conference Proceedings (1993 to 1 October 2013). We placed no restrictions on the language or date of publication when searching the electronic databases.

We contacted study authors to obtain missing information.

MAIN RESULTS

We included two trials in this review, with 62 participants included in the analyses. Both trials were conducted in university dental schools in the USA and compared the effects of oral penicillin V potassium (penicillin VK) versus a matched placebo given in conjunction with a surgical intervention (total or partial pulpectomy) and analgesics to adults with acute apical abscess or symptomatic necrotic tooth (no signs of spreading infection or systemic involvement (fever, malaise)). We assessed one study as having a high risk of bias and the other study as having unclear risk of bias.The primary outcome variables presented were participant-reported pain and swelling (one trial also reported participant-reported percussion pain). One study reported the type and number of analgesics taken by participants. One study recorded the incidence of postoperative endodontic flare-ups (people who returned with symptoms that necessitated further treatment). Adverse effects as reported in one study were diarrhoea (one participant, placebo group) and fatigue and reduced energy postoperatively (one participant, antibiotic group). No studies reporting quality of life measurements were suitable for inclusion. Objective 1: systemic antibiotics versus placebo with surgical intervention and analgesics for symptomatic apical periodontitis or acute apical abscess. Two studies provided data for the comparison between systemic antibiotics (penicillin VK) and a matched placebo for adults with acute apical abscess or a symptomatic necrotic tooth. Participants in one study all underwent a total pulpectomy of the affected tooth while participants in the other study had their tooth treated by either partial or total pulpectomy. Participants in both trials received oral analgesics. There were no statistically significant differences in participant-reported measures of pain or swelling at any of the time points assessed within the review. The MD for pain (short ordinal numerical scale 0 to 3) was -0.03 (95% CI -0.53 to 0.47) at 24 hours; 0.32 (95% CI -0.22 to 0.86) at 48 hours and 0.08 (95% CI -0.38 to 0.54) at 72 hours. The SMD for swelling was 0.27 (95% CI -0.23 to 0.78) at 24 hours; 0.04 (95% CI -0.47 to 0.55) at 48 hours and 0.02 (95% CI -0.49 to 0.52) at 72 hours. The body of evidence was assessed as at very low quality. Objective 2: systemic antibiotics without surgical intervention for adults with symptomatic apical periodontitis or acute apical abscess. We found no studies that compared the effects of systemic antibiotics with a matched placebo delivered without a surgical intervention for symptomatic apical periodontitis or acute apical abscess in adults.

AUTHORS' CONCLUSIONS

There is very low quality evidence that is insufficient to determine the effects of systemic antibiotics on adults with symptomatic apical periodontitis or acute apical abscess.

Pain and swelling after periapical surgery related to the hemostatic agent used: anesthetic solution with vasoconstrictor or aluminum chloride

OBJECTIVE

To assess pain and swelling in the first 7 days after periapical surgery and their relationship with the agent used for bleeding control.

STUDY DESIGN

A prospective study was conducted between October 2006 and March 2009. Patients subjected to root surgery, who completed the questionnaire and who consented to the postoperative instructions were included in the study. The subjects were divided into two groups according to the hemostatic agent used: A) gauze impregnated with anesthetic solution with vasoconstrictor; or B) aluminum chloride. The patients were administered a questionnaire, and were asked to record the severity of their pain and swelling on a plain horizontal visual analog scale (VAS). Data were recorded by the patients on the first 7 postoperative days. In addition, the patients were asked to record analgesic consumption.

RESULTS

A total of 76 questionnaires (34 in group A and 42 in group B) were taken to be correctly completed. Pain was reported to be most intense two hours after surgery. At this point 52.6% of the patients had no pain. Seventy-five percent of the patients consumed analgesics in the first 24 hours. There were no significant differences between the two groups in terms of the intensity of pain or in the consumption of analgesics. Swelling reached its maximum peak on the second day; at this point, 60.6% of the patients suffered mild or moderate swelling. The Expasyl group showed significantly greater swelling than the gauzes group.

CONCLUSION

The type of hemostatic agent used did not influence either the degree of pain or the need for analgesia among the patients in this study. However, the patients belonging to the Expasyl group suffered greater swelling than the patients treated with gauzes impregnated with anesthetic solution with vasoconstrictor.

In vitro and in vivo inhibitory effect of three Cox-2 inhibitors and epithelial-to-mesenchymal transition in human bladder cancer cell lines

Background:

Although the anti-tumour effect of cyclooxygenase-2 (Cox-2) inhibitors in invasive bladder cancer has been confirmed, its mechanisms of action are unclear. Recently, the concept of an epithelial-to-mesenchymal transition (EMT) promoting carcinoma progression has been suggested, and a key feature of the EMT is the downregulation of E-cadherin. In this study, we investigated the effect of Cox-2 inhibitors on reversal EMT and tumour growth inhibition in bladder cancer cells.

Methods:

We used three Cox-2 inhibitors, etodolac, celecoxib and NS-398 and three human bladder cancer cell lines, T24, 5637 and KK47, in this study. T24 xenograft tumour mouse model was used in the in vivo study.

Results:

Within the clinical drug concentrations, only etodolac showed the in vitro growth inhibition in T24 not in the other cell lines. Etodolac reduced SNAIL mRNA and vimentin cell surface expression, and induced E-cadherin mRNA and E-cadherin cell surface expression, in T24. Etodolac also most strongly inhibited the cell migration of T24 in vitro and showed the highest tumour growth inhibition in T24 tumour in vivo.

Conclusion:

Etodolac at clinical doses exhibited induced in vitro and in vivo anti-tumour effects and reversal effect of EMT in T24. These results suggest that etodolac is a good candidate for an anti-tumour or chemopreventive reagent for high-grade bladder cancer.

Dexamethasone decreases oxycodone consumption following osteotomy of the first metatarsal bone: a randomized controlled trial in day surgery

BACKGROUND

Dexamethasone may improve multimodal pain management following painful orthopedic day surgery procedures, and decrease the need for post-operative opioids. We hypothesized that dexamethasone would reduce the need for oxycodone after surgical correction of hallux valgus.

METHODS

Sixty patients planned to undergo unilateral osteotomy of the first metatarsal as a day surgery procedure were randomized to receive pre-operatively and 24 h afterwards, orally either dexamethasone 9 mg or placebo. For pain medication, paracetamol and oxycodone capsules for rescue medication were given. The study ended on the evening of the third post-operative day (POD). The primary endpoint was the cumulative oxycodone consumption. Secondary endpoints were maximal pain scores before oxycodone intake and daily oxycodone doses. In addition, adverse effects were documented.

RESULTS

Twenty-five patients in both groups completed the study. The total median (range) oxycodone consumption during the study period was 45 (0-165) mg in the dexamethasone group and 78 (15-175) mg in the placebo group (P=0.049). The major differences in oxycodone consumption were seen on PODs 0-1. In the dexamethasone group, patients reported significantly lower pain scores on PODs 0-1, and significantly less nausea on POD 1. On PODs 2-3 no differences were seen. However, at 2 weeks post-operatively, patient satisfaction to drug therapy did not differ - in both groups 81% would have chosen the same medication again.

CONCLUSION

Oral dexamethasone combined with paracetamol significantly reduced total oxycodone consumption following surgical correction of hallux valgus.

Effect of pretreatment dexamethasone on postendodontic pain

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.

Single dose oral etodolac for acute postoperative pain in adults

BACKGROUND

Etodolac is a selective cyclo-oxygenase-2 (COX-2) inhibitor, with evidence of efficacy in osteoarthritis and rheumatoid arthritis. Its analgesic efficacy in postoperative pain has not been clearly established. There are no systematic reviews on Etodolac's use in this condition.

OBJECTIVES

To assess the analgesic efficacy of etodolac in single oral doses for moderate and severe postoperative pain.

SEARCH STRATEGY

We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to May 2009.

SELECTION CRITERIA

Randomised, double blind, placebo-controlled trials of single dose orally administered etodolac (any formulation) in adults with moderate to severe acute postoperative pain.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk (RR) and number needed to treat to benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected.

MAIN RESULTS

Nine studies (1459 participants) compared etodolac and placebo. Studies were of adequate reporting quality, and the majority of participants had pain following dental extractions. The dose of etodolac used was 25 mg to 1200 mg, with most of the information for 100 mg and 200 mg. For at least 50% pain relief over 4 to 6 hours compared with placebo the NNT for etodolac 100 mg (498 participants) was 4.8 (3.5 to 7.8) and for etodolac 200 mg (670 participants) it was 3.3 (2.7 to 4.2). Very limited information with the extended release formulation did not suggest improved benefit for this outcome.The proportion of participants with at least 50% pain relief was 41% with 100 mg and 44% with 200 mg. Remedication was needed by about 60% with etodolac 200 mg or 400 mg over 6 to 8 hours, compared with almost 80% with placebo.Adverse events were uncommon, and not significantly different form placebo.

AUTHORS' CONCLUSIONS

Etodolac 200 mg may be a useful analgesic in postoperative pain, with efficacy similar to paracetamol 1000 mg and celecoxib 200 mg. Higher doses may provide analgesia equivalent to more commonly used drugs, such as ibuprofen 400 mg, naproxen 500 mg and diclofenac 50 mg.

Pain and swelling after periapical surgery related to oral hygiene and smoking

OBJECTIVES

To evaluate pain and swelling during the first week after periapical surgery and its relation to patient age, gender, oral hygiene, and smoking.

STUDY DESIGN

One hundred two patients (31 men and 71 women) with a mean age of 40.2 years underwent periapical surgery. Age, gender, and oral hygiene and cigarette smoking before and during the postoperative course were noted. Pain and swelling scores were recorded on a descriptive 4-point scale at 2, 6, and 12 hours after surgery, and each day thereafter for 1 week. The data were statistically evaluated for significant differences.

RESULTS

The highest intensity of pain occurred during the first 48 hours, and swelling peaked on the second postoperative day. Patient age and gender had no significant effect on postoperative symptoms (P > .05). Patients with poor oral hygiene before surgery presented greater pain and swelling during the first postsurgical hours, and smokers before surgery also suffered more pain. The number of cigarettes smoked in the postoperative period and oral hygiene after surgery had no effect on pain or inflammation (P > .05).

CONCLUSIONS

Periapical surgery caused little pain and moderate swelling during the first 2 days after the intervention; these findings were more distinct in patients with poor oral hygiene before surgery and in smokers.
