Mazumder S, Bindu S, Debsharma S, Bandyopadhyay U. Induction of mitochondrial toxicity by non-steroidal anti-inflammatory drugs (NSAIDs): The ultimate trade-off governing the therapeutic merits and demerits of these wonder drugs. Biochem Pharmacol 2024; 228:116283. [PMID: 38750902 DOI: 10.1016/j.bcp.2024.116283] [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: 01/14/2024] [Revised: 05/08/2024] [Accepted: 05/11/2024] [Indexed: 05/20/2024]
Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are most extensively used over-the-counter FDA-approved analgesic medicines for treating inflammation, musculoskeletal pain, arthritis, pyrexia and menstrual cramps. Moreover, aspirin is widely used against cardiovascular complications. Owing to their non-addictive nature, NSAIDs are also commissioned as safer opioid-sparing alternatives in acute trauma and post-surgical treatments. In fact, therapeutic spectrum of NSAIDs is expanding. These "wonder-drugs" are now repurposed against lung diseases, diabetes, neurodegenerative disorders, fungal infections and most notably cancer, due to their efficacy against chemoresistance, radio-resistance and cancer stem cells. However, prolonged NSAID treatment accompany several adverse effects. Mechanistically, apart from cyclooxygenase inhibition, NSAIDs directly target mitochondria to induce cell death. Interestingly, there are also incidences of dose-dependent effects where NSAIDs are found to improve mitochondrial health thereby suggesting plausible mitohormesis. While mitochondria-targeted effects of NSAIDs are discretely studied, a comprehensive account emphasizing the multiple dimensions in which NSAIDs affect mitochondrial structure-function integrity, leading to cell death, is lacking. This review discusses the current understanding of NSAID-mitochondria interactions in the pathophysiological background. This is essential for assessing the risk-benefit trade-offs of NSAIDs for judiciously strategizing NSAID-based approaches to manage pain and inflammation as well as formulating effective anti-cancer strategies. We also discuss recent developments constituting selective mitochondria-targeted NSAIDs including theranostics, mitocans, chimeric small molecules, prodrugs and nanomedicines that rationally optimize safer application of NSAIDs. Thus, we present a comprehensive understanding of therapeutic merits and demerits of NSAIDs with mitochondria at its cross roads. This would help in NSAID-based disease management research and drug development.

Choi SY, Ok SM, Jeong SH, Ahn YW, Jeon HM, Ju HM. The Potential of Percent Agreement as an Adjunctive Diagnostic Tool for Acute Temporomandibular Disorder. J Clin Med 2024; 13:5360. [PMID: 39336847 PMCID: PMC11432075 DOI: 10.3390/jcm13185360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2024] [Revised: 09/03/2024] [Accepted: 09/09/2024] [Indexed: 09/30/2024] Open
Abstract
Background/Objectives: It is well established that individuals with chronic temporomandibular disorder (TMD) exhibit differences in their physical and psychosocial characteristics from those with acute TMD. However, few studies have analyzed the physical and psychosocial characteristics of patients with acute TMD. The objective of this cross-sectional study is twofold: first, to ascertain whether there are differences in physical and psychosocial factors among patients with acute TMD based on the percent agreement between patient-reported pain sites and pain sites identified through standardized palpation and, second, to determine the potential of percent agreement as a diagnostic and prognostic factor. Methods: We analyzed physical and psychosocial factors in 309 patients diagnosed with acute TMD. Of these, 171 patients were selected for an analysis of their response to treatment. These patients were divided into three groups based on their percent agreement: Group A (agreement under 80%), Group B (agreement 80-89%), and Group C (agreement 90% or over) in the initial analysis and Group a (agreement under 80%), Group b (agreement 80-89%), and Group c (agreement 90% or over) in the subsequent analysis. This study was approved by the Ethics Committee of Pusan National University Dental Hospital (IRB No. 2023-05-011, 25 May 2023). Results: The lower the percent agreement, the greater the parafunctional oral habits, stress, chronicity, somatization, depression, anxiety, and number of painful sites. A lower percent agreement was associated with poorer treatment outcomes. The percent agreement demonstrated a 41.2% capacity to predict residual pain after treatment. Conclusions: Clinicians can utilize percentage agreement as an adjunctive diagnostic tool to provide more suitable treatments to patients.

Oral Maxillofac Surg 2024; 28:1105-1115. [PMID: 38910211 DOI: 10.1007/s10006-024-01274-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 06/17/2024] [Indexed: 06/25/2024]
Abstract
PURPOSE This study aims to conduct a thorough analysis, both quantitative and qualitative, of bibliometric parameters related to preemptive analgesia (PA) in oral surgical procedures (OSP). METHODS Research trends on PA in OSP using ibuprofen were reviewed through bibliometric analysis of 68 journal articles published from 1991 to 2022 in the Web of Science database. Bibliometric indicators were applied to analyze the journal article data, including the annual distribution of publications and literature growth, document types, citation indicators to measure qualitative research performance, and keyword mapping to identify research trends. The results were imported into RStudio, and the Bibliometrix package was used to prepare and analyze the metadata. RESULTS The 68 included articles received a total of 900 citations, ranging from 1 source to 72 citations with some fluctuations. The papers on PA in OSP using ibuprofen had an average of 16.85 citations per paper. These publications were originated from 25 countries, with the highest contributions from Brazil (n = 17), the USA (n = 13), and Turkey (n = 8). The top five major contributing journals were the International Journal of Oral and Maxillofacial Surgery, Journal of Oral and Maxillofacial Surgery, Journal of Cranio-Maxillo-Facial Surgery, Journal of Periodontology, and Acta Odontologica Scandinavica, representing more than half of all selected papers. CONCLUSION Papers focused on PA in OSP received numerous citations. The citation per article correlated with the number of publications at the affiliation, author, country, and journal levels. However, there is still a scarcity of studies in this field.

Abstract
Thirty-three 1,3-dihydro-2H-indolin-2-one derivatives bearing α, β-unsaturated ketones were designed and synthesized via the Knoevenagel condensation reaction. The cytotoxicity, in vitro anti-inflammatory ability, and in vitro COX-2 inhibitory activity of all the compounds were evaluated. Compounds 4a, 4e, 4i-4j, and 9d exhibited weak cytotoxicity and different degrees of inhibition against NO production in LPS-stimulated RAW 264.7 cells. The IC50 values of compounds 4a, 4i, and 4j were 17.81 ± 1.86 μM, 20.41 ± 1.61 μM, and 16.31 ± 0.35 μM, respectively. Compounds 4e and 9d showed better anti-inflammatory activity with IC50 values of 13.51 ± 0.48 μM and 10.03 ± 0.27 μM, respectively, which were lower than those of the positive control ammonium pyrrolidinedithiocarbamate (PDTC). Compounds 4e, 9h, and 9i showed good COX-2 inhibitory activities with IC50 values of 2.35 ± 0.04 µM, 2.422 ± 0.10 µM and 3.34 ± 0.05 µM, respectively. Moreover, the possible mechanism by which COX-2 recognized 4e, 9h, and 9i was predicted by molecular docking. The results of this research suggested that compounds 4e, 9h, and 9i might be new anti-inflammatory lead compounds for further optimization and evaluation.

Abstract
The present study discusses comparative structural features of fourteen multicomponent solids of two non-steroidal anti-inflammatory drugs, Niflumic and Mefenamic acids, with amine and pyridine-based coformers. All the solids were structurally characterized through PXRD, SCXRD, DSC, and the monophasic nature of some of the solids was established through Rietveld refinement. The solid forms include salt, cocrystal, hydrate, and solvate. Except for two, all the solids reported here showed relatively higher solubility compared to the acids. The difference in pKa and similarity in structural features of both the molecules enabled us to study the effect of ΔpKa on crystallization outcome systematically. The structures of all the solids are described through acid-pyridine synthon perspective.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic has impeded access to timely dental care, and there is an urgent need for adjuvant therapies that can reduce orofacial pain in emergencies. Aims To provide information on the benefits and limitations of eight representative home remedies as palliative care for orofacial pain during the coronavirus disease 2019 (COVID-19) pandemic. Methods PubMed and Medline were electronically searched for eight home remedies for orofacial pain that can be used in COVID-19. Papers published in English in the past 30 years were considered. Among the published studies suitable for the research purpose, those in which the abstract and body text were confirmed were targeted, and duplicate studies were excluded. Finally, 86 studies were included. Results There is extensive and high-level scientific evidence for the application of tooth brushing and flossing, mouth rinsing with chlorhexidine, use of over-the-counter pain medication, and application of cryotherapy in emergencies. Gargling with salt water, brushing with bamboo salt, gargling with garlic juice, and oil pulling are traditional methods used for centuries. The use of natural products for orofacial pain has a significant empirical effect but has weak scientific evidence. Conclusions Knowing the correct application method, effects, and side effects is desirable to use these methods appropriately in emergencies. However, scientific evidence is unclear and generally lacking for home remedies to be the main treatment strategy, and there are clear limitations to their use as a single main treatment.

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

Abstract
Background The preemptive use of anti-inflammatory drugs, such as corticosteroids and NSAIDs, has the potential to reduce pain, swelling and trismus following oral surgery. The aim of this study was to compare the efficacy of dexamethasone and ketorolac tromethamine in reducing pain, swelling and trismus after mandibular third molar removal.
Material and Methods The researches implemented a triple-blind, randomized clinical trial. The study was conducted with ASA I individuals aging between 18 and 35 years, which were randomized and submitted to two interventions, one with 8mg dexamethasone and the other with 20mg ketorolac tromethamine given 1h before the procedure. The primary predictor variable was the use of dexamethasone or ketorolac. The primary outcome variable was the postoperative pain level, measured with a Visual Analogue Scale. The secondary outcome variables were the amount of rescue analgesic consumed, swelling and trismus. Repeated-measures ANOVA and t-test for paired samples were used to compare the means. Significance was set at p < 0.05.
Results Fifty individuals were randomized and allocated to intervention, and the sample was composed of 40 subjects who completed the study (27 female and 13 male). Dexamethasone, when compared to ketorolac tromethamine, showed a significantly higher reduction in pain level at 8h, 16h, 24h, 32h, 40h and 72h, in swelling and trismus at 24h, 48h, 72h and 7 days and in total number of rescue analgesics taken up to 72h postoperative (p < 0.05).
Conclusions The clinical performance of dexamethasone in controlling pain, swelling and trismus after mandibular third molar removal was superior to ketorolac tromethamine’s. Key words:Third Molar, anti-inflammatory agents, dexamethasone, ketorolac.

Abstract
Dentists prescribe several types of drugs such as anti-inflammatory medicines in their practice in order to manage pain. An adequate knowledge of anti-inflammatory drugs' characteristics is mandatory for a reasonable prescription to ensure patients safety. The study aimed to describe dentists' anti-inflammatory drugs prescription in dental practice. Materials and Methods. This study was conducted on independent practice dentists working in the region of Tunis. A questionnaire was made on “Google forms” and sent to all of them via personal emails. The questionnaire included demographic data and 13 questions about anti-inflammatory medicines: indications and contraindications, the side effects, and their prescription in dental practice. Data analysis was performed on SPSS software version 20.0 (trial version), using the χ2 test for statistical analysis. Results. Two hundred dentists participated to the survey. The female gender was predominant (70%). More than half of the responders were recently graduated and working in their own dental offices. The present study showed that 60% of dentists rarely prescribe anti-inflammatory drugs. Ibuprofen was prescribed by 82% of the dentists. Next came dexamethasone acetate (68.2%). The most frequent indication was postoperative pain (65%). Gastric problem was found to be the most mentioned adverse effect (69%). Thus, 72% of the dentists prescribed proton pump inhibitors with AI. Conclusion. According to this study, dentists have a lack of knowledge and awareness about some contraindications, side effects, and drugs interactions. Thus, knowledge updating, practices assessment, and continuous education are always required to avoid drug iatrogenesis.

Abstract
Background:
Crown lengthening surgery is one of the most common periodontal surgeries. The analgesic effects of benzydamine and ibuprofen tablets have been proven in various studies. The purpose of this study was to compare benzydamine hydrochloride mouthwash 0.15% with ibuprofen in decreasing the pain of patients with crown lengthening surgery who had referred to the Periodontology Department of Yazd Dentistry School in 2015.
Materials & Methods:
In this clinical trial study, 36 patients aged 30 to 60 years who referred to the Periodontal Department of the Dental Faculty of Yazd University of Medical Sciences needing a crown lengthening surgery were randomly allocated to two groups. The patients of the first group were asked to wash their mouth using benzydamine hydrochloride mouthwash 0.15% after the surgery according to the instructed protocol and the patients in the second group were asked to take an ibuprofen tablet (400 mg) every 6 hours. After 24 hours, the level of pain was measured by using the numerical criteria of the Visual Analog Scale (VAS) and the data were analyzed using SPSS software version 18. T test and Mann-Whitney test were used as appropriate.
Results:
77.8% of the participants in the first group had mild pain and rest of the participants had moderate pain. 77.8% of the participants who used ibuprofen tablet reported mild pain, 16.7% had moderate pain and 5.6% had severe pain. The results did not illustrate more effect of ibuprofen on the reduction of pain after crown lengthening surgery compared with benzydamine hydrochloride 0.15% (P=0.48).
Conclusion:
In the present study, there were no changes in the VAS index between the two groups. Therefore, in order to decrease pain after periodontal surgery, benzydamine hydrochloride mouthwash can be widely used as it has fewer side effects, lower price, and similar effects with ibuprofen.

Abstract
Owing to its biocompatibility and corrosion resistance, titanium is one of the most commonly used implantable biomaterials. Numerous in vitro and in vivo investigations have established that titanium surfaces with a nanoscale topography outperform conventional smooth or micro-rough surfaces in terms of achieving desirable bonding with bone (i.e. enhanced bioactivity). Among these nanoscale topographical modifications, ordered nanostructures fabricated via electrochemical anodization, especially titania nanotubes (TNTs), are particularly attractive. This is due to their ability to augment bioactivity, deliver drugs and the potential for easy/cost-effective translation into the current implant market. However, the potential of TNT-modified implants to modulate the host immune-inflammatory response, which is critical for achieving timely osseointegration, remains relatively unexplored. Such immunomodulatory effects may be achieved by modifying the physical and chemical properties of the TNTs. Furthermore, therapeutic/bioactive enhancements performed on these nano-engineered implants (such as antibacterial or osteogenic functions) are likely to illicit an immune response which needs to be appropriately controlled. The lack of sufficient in-depth studies with respect to immune cell responses to TNTs has created research gaps that must be addressed in order to facilitate the design of the next generation of immuno-modulatory titanium implants. This review article focuses on the chemical, topographical and mechanical features of TNT-modified implants that can be manipulated in order to achieve immuno-modulation, as well as providing an insight into how modulating the immune response can augment implant performance.

Abstract
Inflammation remains a key event during most of the diseases and physiological imbalance. Acute inflammation is an essential physiological event by immune system for a protective measure to remove cause of inflammation and failure of resolution lead to chronic inflammation. Over a period of time, a number of drugs mostly chemical have been deployed to combat acute and chronic inflammation. Recently, enzyme based anti-inflammatory drugs became popular over conventional chemical based drugs. Serratiopeptidase, a proteolytic enzyme from trypsin family, possesses tremendous scope in combating inflammation. Serine protease possesses a higher affinity for cyclooxygenase (COX-I and COX-II), a key enzyme associated with production of different inflammatory mediators including interleukins (IL), prostaglandins (PGs) and thromboxane (TXs) etc. Currently, arthritis, sinusitis, bronchitis, fibrocystic breast disease, and carpal tunnel syndrome, etc. are the leading inflammatory disorders that affected the entire the globe. In order to conquer inflammation, both acute and chronic world, physician mostly relies on conventional drugs. The most common drugs to combat acute inflammation are Nonsteroidal anti-inflammatory drugs (NSAIDs) alone and or in combination with other drugs. However, during chronic inflammation, NSAIDs are often used with steroidal drugs such as autoimmune disorders. These drugs possess several limitations such as side effects, ADR, etc. In order to overcome these limitations and complications, enzyme based drugs (anti-inflammatory) emerged, and aim for a new high since the last decade. Serine protease, the largest proteolytic family has been reported for several therapeutic applications, including anti-inflammatory. Serratiopeptidase is a leading enzyme which has a very long history in medical as an effective anti-inflammatory drug. Current study emphasizes present scenario and future prospect of serratiopeptidase as an anti-inflammatory drug. The study also illustrates a comparative analysis of conventional drugs and enzyme based therapeutic to combat inflammation.

Abstract
INTRODUCTION The transmucosal nature of dental implants presents a unique therapeutic challenge, requiring not only rapid establishment and subsequent maintenance of osseointegration, but also the formation of resilient soft tissue integration. Key challenges in achieving long-term success are sub-optimal bone integration in compromised bone conditions and impaired trans-mucosal tissue integration in the presence of a persistent oral microbial biofilm. These challenges can be targeted by employing a drug-releasing implant modification such as TiO2 nanotubes (TNTs), engineered on titanium surfaces via electrochemical anodization. Areas covered: This review focuses on applications of TNT-based dental implants towards achieving optimal therapeutic efficacy. Firstly, the functions of TNT implants will be explored in terms of their influence on osseointegration, soft tissue integration and immunomodulation. Secondly, the developmental challenges associated with such implants are reviewed including sterilization, stability and toxicity. Expert opinion: The potential of TNTs is yet to be fully explored in the context of the complex oral environment, including appropriate modulation of alveolar bone healing, immune-inflammatory processes, and soft tissue responses. Besides long-term in vivo assessment under masticatory loading conditions, investigating drug-release profiles in vivo and addressing various technical challenges are required to bridge the gap between research and clinical dentistry.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are well-known inhibitors of cyclooxygenases (COXs) and are widely used for the treatment of inflammatory pain; however several NSAIDs display COX-independent analgesic action including the inhibition of voltage-gated Na(+) channels expressed in primary afferent neurons. In the present study, we examined whether NSAIDs modulate tetrodotoxin-resistant (TTX-R) Na(+) channels and if this modulation depends on the extracellular pH. The TTX-R Na(+) currents were recorded from small-sized trigeminal ganglion neurons by using a whole-cell patch clamp technique. Among eight NSAIDs tested in this study, several drugs, including aspirin and ibuprofen, did not affect TTX-R Na(+) channels either at pH 7.4 or at pH 6.0. However, we found that indomethacin, and, to a lesser extent, ibuprofen and naproxen potently inhibited the peak amplitude of TTX-R Na(+) currents at pH 6.0. The indomethacin-induced inhibition of TTX-R Na(+) channels was more potent at depolarized membrane potentials. Indomethacin significantly shifted both the voltage-activation and voltage-inactivation relationships to depolarizing potentials at pH 6.0. Indomethacin accelerated the development of inactivation and retarded the recovery from inactivation of TTX-R Na(+) channels at pH 6.0. Given that indomethacin and several other NSAIDs could further suppress local nociceptive signals by inhibiting TTX-R Na(+) channels at an acidic pH in addition to the classical COX inhibition, these drugs could be particularly useful for the treatment of inflammatory pain.

Abstract
Background This study aims to evaluate and compare the effect of pre-procedural administration of acetaminophen, ibuprofen, and meloxicam in reducing pain after separator placement. Methods Three hundred twenty-one patients who needed orthodontic treatment and aged above 15 were randomly assigned to one of the three study groups: group A: 650 mg acetaminophen, group B: 400 mg ibuprofen, and group C: 7.5 mg meloxicam. All subjects received a single dose of medication 1 h prior to separator placement. Using visual analog scale, patients recorded their pain perception during rest, fitting posterior teeth together, and chewing at time intervals of immediately, 2, 6, 24, and 48 h after separator placement. Results There was no significant difference between acetaminophen, ibuprofen, and meloxicam in post-separator placement pain control when administered 1 h before the procedure. In all the groups, at rest, pain level elevated after separator placement and reached its peak at 24 h and then subsided until 48 h. But during chewing and fitting of the posterior teeth, some of the groups reached a peak in pain at 48 h. No significant difference was found in pain experience between males and females. Conclusions Meloxicam can be used as an effective analgesic in orthodontic pain control considering it has less gastric side effects compared to the conventional nonsteroidal anti-inflammatory drugs.

Abstract
Objective. Understanding factors while selecting an analgesic and its usage pattern by Indian healthcare practitioners (HCPs). Methods. Questionnaire-based survey was conducted among six healthcare specialties. Results. Total 448 HCPs participated. Patient's age (72.8%, 74.4%, 87.5%, and 78.9%) and duration of therapy (70.8%, 66.2%, 69.6%, and 73.6%) were main attributes for selecting an opioid according to general practitioners (GPs), dentists, consulting physicians (CPs), and surgeons, respectively. Patient's age was important factor while selecting NSAID according to 77.60%, 66.91%, and 84.20% of GPs, dentists, surgeons, respectively. For mild pain, paracetamol was the choice according to 77%, 78.57% and 74% of GPs, CPs, and surgeons, respectively. For moderate pain, 77%, 87.50%, 68%, and 80.30% of GPs, CPs, surgeons and orthopedicians, respectively, preferred the use of paracetamol + tramadol combination. For moderate pain, NSAID + paracetamol and paracetamol+diclofenac were used by 68.94% and 47.73% of orthopedicians, respectively. Lack of pain clinic (38.8%) in city was commonly cited reason for not referring patients to pain clinics. Conclusion. Patient's age, duration of therapy, comorbid conditions, frequency of dosing, and severity of pain are important parameters while selecting analgesics. Paracetamol and its combinations are commonly used for mild and moderate pain, respectively. Pain clinics currently have limited presence in India.

Abstract
AIM Until recently, adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs) on osseointegration of dental implants were unknown. Hence, this study investigated the short- and long-term effects of a 7-day regimen of parecoxib and diclofenac sodium on osseointegration of dental implants in calvarial bone. MATERIAL AND METHODS Eighteen New Zealand White rabbits were randomly allocated into three groups (each n = 6): Control group with no postoperative pain killers (Group A), diclofenac group (Group B) and parecoxib group (Group C). In each animal, one dental implant was placed into the calvarial bone (total n = 18). Three rabbits from each group were sacrificed in Week 4. The other three rabbits from each group were sacrificed in Week 12 postoperatively. The implant together with the calvarial bone and dura mater was harvested and subjected to micro-computed tomography (micro-CT) and histomorphometric analysis. RESULTS Quantitative analysis of micro-CT data and histomorphometric data neither revealed any statistically significant (P ≤ 0.05) differences between the three different groups related to osseointegration nor between different time points of observation. CONCLUSION In rabbits, a 7-day regimen of appropriate doses of diclofenac sodium and parecoxib did not adversely affect osseointegration of dental implants and bone healing in calvaria, neither short nor long term (12 weeks).

Abstract
This article presents selected cases of patients with functional disorders of the stomatognathic system. This group of patients had a need to made different types of removable occlusal splints. In the past, occlusal appliances were made mostly using self-cured acrylate materials, which for many years had no replacements. The rapid development of dental materials technology led to creation of thermo-formable materials and resins, which can successfully replace traditional acrylic materials in daily clinical practice. A practical application of light-cured resin in the fabrication of the occlusal splints in two clinical cases is reported and discussed herein.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs), including diclofenac, are the mainstay of analgesic and anti-inflammatory treatment in dentistry. Diclofenac epolamine [diclofenac N-(2-hydroxyethyl)pyrrolidine; DHEP] is a diclofenac salt with greater water solubility and better cutaneous absorption properties than other commonly used forms of the drug. IBSA has recently developed a mouthwash formulation of DHEP for the topical treatment of inflammatory conditions of the oral cavity. OBJECTIVE The aim of this study was to compare the efficacy and tolerability of DHEP mouthwash (Osmal®) with that of a reference product (commercially available diclofenac mouthwash). METHODS This was a randomized, investigator-blind, parallel-group, controlled, phase III study that enrolled 80 patients with conditions affecting the oral cavity, characterized by an inflammatory component, and eligible for analgesic and anti-inflammatory treatment. Patients were randomized 1:1 to DHEP mouthwash (0.103% DHEP in aqueous solution) or to diclofenac mouthwash (0.074% free diclofenac in aqueous solution). The treatment regimen was the same in both groups: 1-minute rinse with 15 mL of mouthwash, twice daily for 7 days. Visits were scheduled at study inclusion (D0), and 3 days (D3) and 7 days (D7) after treatment initiation. During each visit assessments were made of pain severity (using a 5-point semi-quantitative scale and a 100-mm visual analogue scale [VAS]) and inflammatory signs (using a 5-point scale). The primary study endpoint was the change in pain severity scores from D0 to D3 and D7. Secondary endpoints included effects of treatment on inflammation score, quality of sleep, compliance with treatment and the safety and tolerability of treatment. RESULTS The two treatment arms were homogeneous in terms of patient characteristics. The most prevalent oral condition was gingivitis. Overall both topical treatments were effective in alleviating pain and inflammation, as evidenced by decreases in pain and inflammation scores within 3 days after treatment initiation. Notably, a significantly greater proportion of patients treated with DHEP were free of pain and inflammatory symptoms at D3 compared with those treated with the diclofenac mouthwash (40% vs 20% of patients; p < 0.05). Also, DHEP was associated with more marked, but not statistically significant, decreases in VAS pain scores versus baseline after 3 days' treatment. Compliance with both treatments was good and both mouthwashes were well tolerated. CONCLUSION DHEP mouthwash was at least as effective as diclofenac mouthwash at alleviating pain and inflammation symptoms and is well tolerated in patients with painful inflammatory conditions of the oral cavity. The potential of DHEP mouthwash deserves to be investigated in a larger patient population.

Abstract
OBJECTIVE The aim of this study was to evaluate the clinical effects of oral glucosamine sulfate, compared with placebo, on osteoarthritis in the temporomandibular joints (TMJs). STUDY DESIGN Fifty-nine patients, consecutive referrals fulfilling the research diagnostic criteria for temporomandibular disorder for TMJ osteoarthritis, confirmed roentgenographically, were randomized to the daily intake of 1,200 mg glucosamine sulfate or identical placebo capsules in this double-blind trial. Pain on visual and verbal rating scales and opening capacity were registered before and after 6 weeks of medication. RESULTS The signs and symptoms were similar in the groups initially and they were ameliorated over time. No differences in improvement between groups after treatment were indicated. Eight patients in the glucosamine group and 2 in the placebo group stopped the medication prematurely. Gastrointestinal side effects were reported by a total of 10 and 3 patients, respectively. CONCLUSIONS Oral glucosamine sulfate was not superior to placebo in reducing signs and symptoms of osteoarthritis in the TMJs in this short-term trial.

Abstract
OBJECTIVE Lower third molar removal provides a clinical model for studying analgesic drugs. The present study's aim was to compare the clinical efficacy of sublingual ketorolac and sublingual piroxicam in managing pain, trismus and swelling after lower third molar extraction in adult volunteers. STUDY DESIGN In this double-blinded, randomized, crossover investigation, 47 volunteers received for 4 days ketorolac sublingually (10 mg 4 times daily) and piroxicam sublingually (20 mg once daily) during 2 separate appointments after lower third molar extraction of symmetrically positioned lower third molars. A surgeon evaluated objective parameters (surgery duration, mouth opening, rescue analgesic medication, and facial swelling) and volunteers documented subjective parameters (postoperative pain and global evaluation), comparing postoperative results for a total of 7 days after surgery. The means of the objective and subjective parameters were compared for statistical significance (P < .05). RESULTS Volunteers reported low pain scores during the postoperative period when treated with either sublingual ketorolac or piroxicam. Also, volunteers ingested similar amounts of analgesic rescue medication (paracetamol) when they received either drug sublingually (P > .05). Additionally, values for mouth openings measured just before surgery and immediately after suture removal 7 days later were similar among volunteers (P > .05), and the type of nonsteroidal antiinflammatory drug (NSAID) used in this study showed no significant differences between swellings on the second or seventh days after surgery (P > .05). CONCLUSIONS Pain, trismus, and swelling after lower third molar extraction, independent of surgical difficulty, were successfully controlled by sublingual ketorolac (10 mg 4 times daily) or sublingual piroxicam (20 mg once daily), and no significant differences were observed between the NSAIDs evaluated.

Abstract
PURPOSE To compare the pre-emptive analgesic effectiveness of 15 mg of meloxicam and 50 mg of tramadol after mandibular third molar surgery. PATIENTS AND METHODS This pilot study was a double-blind, randomized, parallel-group clinical trial. The patients were randomized into 2 treatment groups, each with 15 patients, by use of a series of random numbers: group A was administered 15 mg of meloxicam intramuscularly (IM) 50 minutes before the surgery and group B was given 50 mg of tramadol IM 50 minutes before the surgery. We evaluated pain intensity, analgesic consumption, swelling, and trismus. RESULTS The group receiving 15 mg of meloxicam IM showed differences in pain intensity evaluated by the area under the curve of the visual analog scale and total analgesic consumption when compared with the group receiving 50 mg of tramadol IM. CONCLUSION The patients receiving 15 mg of preoperative meloxicam had less pain intensity and total analgesic consumption than those receiving 50 mg of preoperative tramadol.

Comparison of oral versus sublingual piroxicam during postoperative pain management after lower third molar extraction. Int J Oral Maxillofac Surg 2010; 40:292-7. [PMID: 21144709 DOI: 10.1016/j.ijom.2010.10.026] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2010] [Revised: 09/29/2010] [Accepted: 10/29/2010] [Indexed: 11/30/2022]
Abstract
In this study, 53 patients received piroxicam, administered orally or sublingually, after undergoing removal of symmetrically positioned lower third molars, during two separate appointments. This study used a randomized, blind, cross-over protocol. Objective and subjective parameters were recorded for comparison of postoperative results for 7 days after surgery. Patients treated with oral or sublingual piroxicam reported low postoperative pain scores. The patients who received piroxicam orally took a similar average amount of analgesic rescue medication compared with patients who received piroxicam sublingually (p>0.05). Patients exhibited similar values for mouth opening measured just before surgery and immediately following suture removal 7 days later (p>0.05), and showed no significant differences between routes of piroxicam administration for swelling control during the second or seventh postoperative days (p>0.05). In summary, pain, trismus and swelling after lower third molar extraction, independent of surgical difficulty, could be controlled by piroxicam 20mg administered orally or sublingually and no significant differences were observed between the route of delivery used in this study.

Abstract
Historically, individuals with intellectual disability (ID) have been excluded from pain research and assumed to be insensitive or indifferent to pain. The weight of the evidence suggests that individuals with ID have been subject to practices and procedures with little regard for their ability to experience or express pain. A number of issues central to improving understanding of pain in ID will be introduced and current research related to the definition of pain and its social context, underlying sensory and metabolic systems and factors influencing judgments about the ability to experience pain will be reviewed. Accumulating evidence from interdisciplinary research designed to improve assessment, understand individual differences, and evaluate bias and beliefs about pain suggests that new perspectives are emerging and beginning to shape an innovative frontier of research that will ultimately pay tremendous dividends for improving the quality of life of individuals with ID.

Abstract
Ketorolac tromethamine gel (KT gel) and ketorolac tromethamine gel containing genipin (KTG gel) were prepared and their therapeutic effects on periodontitis were evaluated. The skin permeation rate of ketorolac from the KT gel and KTG gel was 5.75+/-0.53 and 5.82 +/- 0.74 microg/cm2/ h, respectively. The skin permeation rate of genipin from the KTG gel was 10.13 +/- 1.47 microg/ cm2/h. The tensile strength of the KTG gel was larger than the KT gel. After 4 weeks, the periodontal pocket depth of the KTG gel group (3.22 +/- 0.20 mm) significantly decreased compared with the non-treated group (4.50 +/- 0.25 mm) and the KT group (3.84 +/- 00.26 mm). The KTG gel did not induce separation of the stratum corneum and subcutaneous tissue, and the collagen layers of the corium were closer, more fibrous, and showed longer connections than in the other groups. The KTG gel appears to be effective against gingivitis in the periodontal pocket through its increased anti-inflammatory activity and the crosslinking of genipin with the biological tissue.

Abstract
MK-0703 is a selective cyclooxygenase-2 inhibitor investigated for the treatment of acute pain and inflammation. The purpose of this single-dose, randomized, double-blind, double-dummy, placebo-controlled, parallel-group study was to compare MK-0703 12.5, 50, and 100 mg with ibuprofen 400 mg or placebo in patients who experienced moderate to severe pain after surgical removal of at least 2 third molars. Overall analgesic effect, duration of analgesic effect, time to onset of analgesic effect, peak analgesic effect, and tolerability were assessed over a 24-hour postdose period. The primary endpoint of this study was total pain relief over 8 hours postdose. The study included 121 patients (mean age, 23 yr); 16, 31, 28, 31, and 15 patients enrolled in the placebo, MK-0703 12.5 mg, MK-0703 50 mg, MK-0703 100 mg, and ibuprofen 400 mg groups, respectively. Both MK-0703 50 and 100 mg were significantly more effective than placebo for all endpoints (P < 0.01) and comparable with ibuprofen 400 mg. The onset of analgesic effect in the MK-0703 50 mg and 100 mg and ibuprofen 400 mg groups did not differ significantly from each other (P > 0.20). MK-0703 was generally well tolerated in single doses up to 100 mg. In summary, MK-0703 50 and 100 mg were efficacious in the treatment of postoperative dental pain and were indistinguishable from the active comparator, ibuprofen 400 mg.

Abstract
UNLABELLED Cyclooxygenase (COX) plays an important role in the induction of pain and inflammation as well as the analgesic actions of NSAIDs and coxibs. This study evaluates the expression of the two isoforms COX-1 and COX-2 in a clinical model in which the surgical removal of impacted third molars is used to evaluate the analgesic activity of anti-inflammatory drugs. A 3-mm punch biopsy was performed on the oral mucosa overlying 1 impacted third molar immediately before extraction of 2 impacted lower third molars. After the second tooth was extracted, a second biopsy was performed adjacent to the surgical site either immediately after surgery or 30, 60, or 120 minutes after surgery. RNA was extracted from the biopsy specimens, and RT-PCR was performed to assess mRNA levels of COX-1, COX-2, and glyceraldehyde-3-phosphate dehydrogenase (G3PDH). The RT-PCR products in the biopsy specimens were normalized to G3PDH and compared with baseline. COX-2 mRNA was progressively increased at 30, 60, and 120 minutes after surgery (P<.05); COX-1 mRNA was transiently decreased at 60 minutes during the postsurgical period (P<.05). The results demonstrate peripheral elevation of COX-2 after tissue injury, which may contribute to increased prostaglandin E(2) at the site of injury, pain onset, and the analgesic activity of both nonselective NSAIDs and selective COX-2 inhibitors. PERSPECTIVE This clinical study uses a physiologically relevant model to determine the time course of expression of COX-1 and COX-2 in acute inflammation of the human oral mucosa. This study furthers our understanding of the contribution of the COX isoforms to acute pain.

Abstract
Fifty patients were scheduled to undergo removal of symmetrically positioned lower third molars in two separate appointments. Meloxicam 7.5 or 15 mg was once daily administered in a double-blind, randomized and crossover manner after the surgery for 4 days. Objective and subjective parameters were recorded for comparison of postoperative courses. Patients treated with 7.5mg meloxicam who underwent osteotomy reported higher pain scores at 1.5, 3, 4, 10, 12 and 16 h (P<0.05) and ingested a greater amount of rescue analgesic medication (P<0.05) than those who did not require osteotomy. A higher percentage of patients who underwent osteotomy medicated with 7.5mg meloxicam needed rescue medication as compared to those who did not require osteotomy (P<0.05). There was a similar mouth opening at suture removal compared with preoperative values for both doses (P>0.05). There were no significant differences concerning swelling observed on the 2nd or 7th postoperative days in comparison with baseline (P>0.05) between the two doses. Pain, trismus and swelling after lower third molar removal not requiring osteotomy can be successfully controlled by a dose regimen of 7.5mg meloxicam once daily. For more aggressive extractions 15 mg meloxicam is advisable.

Abstract
In a prospective, double blind, and randomized study, we compared methylprednisolone and ketoprofen after anesthesia for multiple third molar extraction. In addition to paracetamol, 90 patients were allocated to receive intravenously either ketoprofen 100 mg or methylprednisolone 1 mg/kg. Severity of pain was measured with visual analogue scale (VAS) in recovery room. Sixty-three percent of patients receiving methylprednisolone had a VAS score <30 mm compared with 42% of those receiving ketoprofen (P = 0.04), with no difference in the consumption of morphine. We observed only marginal difference between methylprednisolone and ketoprofen to relieve pain after this surgery.

Abstract
BACKGROUND On the basis of their perceived better safety profile compared with other analgesic agents, cyclo-oxygenase-2 (COX-2) inhibitors have been prescribed frequently as first-line agents to treat acute dental pain. However, recently identified cardiovascular adverse reactions associated with these drugs mandate a reappraisal of their use in dental practice. TYPES OF STUDIES REVIEWED. The authors reviewed 18 clinical studies that evaluated the efficacy of a COX-2 inhibitor for the treatment of acute dental pain. All of the studies used the widely established third-molar surgical extraction model to induce postsurgical inflammatory based pain, and all were randomized, double-blinded and placebo-controlled. However, numerous vagaries in overall study design made direct comparisons difficult. RESULTS None of the studies established any of the COX-2 inhibitors as clearly better than ibuprofen, the current gold standard for the treatment of surgically induced dental pain. However, in single-dosing scenarios, the COX-2 inhibitor often demonstrated a longer duration of action compared with ibuprofen. CLINCAL IMPLICATIONS The evidence to date fails to demonstrate any therapeutic advantage to using a COX-2 inhibitor to treat acute dental pain compared with ibuprofen. In the rare event that a COX-2 inhibitor may be appropriate, the clinician must inform the patient of the potential risks, and the drug should be used for the shortest possible time.

Abstract
UNLABELLED BACKGROUND; Cyclo-oxygenase-2 inhibitors (COX-2i) demonstrate analgesic efficacy for patients who require gastrointestinal safety. The authors discuss the potential benefits and risks of these novel, but expensive, analgesics when used in dentistry. METHODS The authors conducted a MEDLINE search focused on the subject headings of common analgesic drugs and COX-2i, using peer-reviewed journals limited to the English language. They selected for review 127 articles that met the criteria. They also tried to identify any randomized controlled trials pertinent to dentistry and indicative of evidence-based medicine. RESULTS. When comparing COX isoforms (COX-1 and COX-2), the authors found that overlapping and mutually exclusively properties coexist. COX-2i originally were developed to minimize interference with the gastroprotective properties of the COX-1 isoform, while selectively preventing prostanoid synthesis expressed solely at sites of bodily trauma or other inflammation. COX-2i were found to provide pain relief equal to or slightly exceeding that offered by many mild narcotics. They may avoid some of the serious side effects that can occur with even short-term use of nonselective nonsteroidal anti-inflammatory drugs. CONCLUSIONS The pharmacodynamics of COX-2i reveal an agent that includes analgesic, anti-inflammatory and gastroprotective properties but also allows for an undesirable disruption of the delicate hemodynamic balance. CLINICAL IMPLICATIONS Symptomatic and asymptomatic gastroparietic patients who do not have severe cardiovascular, cerebral or renal ischemic disease benefit from use of COX-2i. Long-term use of these agents in medically compromised patients may prove disastrous.

Abstract
OBJECTIVE To evaluate the pain experience following root-end resection and filling with Mineral Trioxide Aggregate or Intermediate Restorative Material. STUDY DESIGN Referred adult patients recruited using strict entry criteria were randomly allocated to receive either material. A standardized surgical technique was employed. Postoperative instructions and a pain questionnaire were given to each patient to record the severity of their pain at 3 time intervals-3-5 hours, 24 hours, and 48 hours after surgery-on a standard visual analog scale (VAS). Patients were also asked to record consumption of any self-prescribed analgesics, the type, and dosage. RESULTS At 3-5 hours after surgery, regardless of the material used, 90% of all patients experienced some level of postoperative pain. Twenty-four hours after surgery 82% of patients experienced pain, as did 72% after 48 hours. Thirty-seven percent of patients did not take any analgesics at all. In order of popularity, the analgesics taken were ibuprofen, acetaminophen, and acetaminophen plus codeine phosphate. The VAS measurements were reduced over time in both treatment groups (P < .001). There was no statistically significant difference in the proportion of subjects taking analgesics in each treatment group. Patients who used analgesics showed higher median VAS measurements at all time periods (P < .05). CONCLUSIONS There was no significant difference in the pain experienced by both treatment groups. The postoperative pain was of a relatively short duration, at its maximum intensity early in the postoperative period but progressively decreased with time. Even if pain relief medication was needed, nonprescription analgesics were adequate and effective.

Abstract
OBJECTIVE To determine the time to onset of analgesia of rofecoxib based on a patient-level meta-analysis of randomized, placebo-controlled, postoperative oral surgery pain studies. METHODS A search on MEDLINE and of Merck data on file was conducted to identify studies that met the inclusion criteria. Meta-analysis inclusion criteria required that patients were treated with a single oral dose of rofecoxib 50 mg when they experienced moderate or severe pain after surgical extraction of > or = 2 third molars; study design involved patient randomization, double-blinding, and matching placebo, and onset data from individual patients were available. The meta-analysis of time to onset also required that studies used the two-stopwatch method. Eleven studies fulfilled the onset criteria and included patients who received a single dose of rofecoxib 50 mg (N = 1220) or placebo (N = 483). These studies were analyzed to determine time to onset of analgesia, time to perceptible pain relief, percentage of patients achieving onset of analgesia, and duration of analgesia. Six of the 11 studies included a nonselective nonsteroidal anti-inflammatory drug (N = 303) and were included in the onset meta-analysis for comparison. The meta-analysis of overall efficacy also required that data on total pain relief scores over 8 hours were available. Over-all effectiveness of analgesia was based on analysis of 13 studies involving 1330 rofecoxib patients and 570 placebo patients on the endpoints of total pain relief scores over 8 hours and patient global assessment of response to therapy at 24 hours. Eight of the 13 studies with a nonselective nonsteroidal anti-inflammatory drug comparator (N = 391) were included for the efficacy meta-analysis. RESULTS Patient demographics and baseline characteristics were similar across treatment groups in each study. Median time to onset of analgesia for rofecoxib was 34 minutes (95% CI, 31-38 minutes), significantly faster than placebo, which did not achieve onset within the 4 hours the assessment was conducted (P < 0.001). Duration of analgesia for rofecoxib 50 mg was > 24 hours. Rofecoxib achieved a greater mean total pain relief score over 8 hours than placebo (17.4 versus 4.4; P < 0.001) and a greater patient response rate on patient global assessment of response to therapy at 24 hours than placebo (73% versus 16%; P < 0.001). Outcomes were similar between the rofecoxib group and the nonselective nonsteroidal anti-inflammatory drug group. CONCLUSION In this meta-analysis of over 1200 rofecoxib-treated patients, a single dose of rofecoxib 50 mg demonstrated a rapid onset of analgesia in approximately half an hour combined with sustained effectiveness, supporting its use as a treatment of acute pain.

Abstract
BACKGROUND To compare the analgesic effect of single doses of etoricoxib 120 mg, oxycodone/ acetaminophen 10 mg/650 mg and codeine/ acetaminophen 60 mg/600 mg in acute pain using the dental impaction model. METHODS In this randomized, double-blind, placebo-controlled, parallel-group study, patients reported pain intensity and pain relief (16 times) and global scores (twice) during a 24-h period. The primary endpoint was the overall analgesic effect, total pain relief over 6 h (TOPAR6). Other endpoints were patient global evaluation, time to onset (2-stopwatch method), duration of analgesic effect (median time to and amount of rescue medication use). Tolerability was evaluated by overall and opioid-related (nausea and vomiting) adverse experiences. RESULTS 302 patients (mean age 23; 63% women; 63 % White) were randomized to etoricoxib 120 mg, oxycodone/acetaminophen 10 mg/650 mg, codeine/acetaminophen 60 mg/600 mg, and placebo (2:2:1:1). Etoricoxib demonstrated significantly greater overall analgesic efficacy (TOPAR6) (13.2 units) versus oxycodone/acetaminophen (10.2 units); and codeine/acetaminophen (6.0 units); p < 0.001 for all. All active treatments were superior to placebo. Median time to onset was significantly (p < 0.001) shorter for oxycodone/acetaminophen (20 min) and numerically but not significantly shorter (p = 0.259) for codeine/acetaminophen (26 min) compared with etoricoxib (40 min). Etoricoxib (24 h) had a significantly longer lasting analgesic effect than oxycodone/acetaminophen (5.3 h), codeine/acetaminophen (2.7 h), and placebo (1.7 h) (p < 0.001 for all). Etoricoxib patients experienced fewer clinical adverse experiences than patients on oxycodone/acetaminophen and codeine/acetaminophen, specifically, significantly (p < 0.05) fewer episodes of nausea. CONCLUSION Etoricoxib 120 mg provided superior overall analgesic effect with a smaller percentage of patients experiencing nausea versus both oxycodone/acetaminophen 10 mg/650 mg and codeine/acetaminophen 60 mg/600 mg.

Abstract
BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed analgesic agents in surgical outpatients. Major limitations of NSAIDs are their gastrointestinal (GI) adverse events (perforation, ulceration, and bleeding), impairment of hemostatic function, and renal failure (with long-term therapy). A new class of NSAIDs, the COX-2 selective inhibitors (CSIs or Coxibs), have been developed with the aim of reducing the GI adverse events of traditional NSAIDs while maintaining their effective anti-inflammatory and analgesic properties. OBJECTIVE This is a narrative review of the literature aimed to discuss analgesic efficacy, clinical safety and cost-benefit ratio of CSIs in the treatment of post-oral surgery pain. METHODS Relevant drug and clinical studies of analgesic efficacy and safety of CSIs in the management of postoperative dental pain were identified through searches of MEDLINE/PubMed, in peer-reviewed journals of medicine and dentistry. The Food and Drug Administration Web site was searched for data of tolerability. Hand-searching included several dental journals and bibliographies of relevant studies. The last electronic search was conducted in April 2003. RESULTS Data from well-designed, randomized, controlled trials of CSIs on the management of post-oral surgery pain indicate that these drugs are as well-effective analgesic agents as traditional NSAIDs and offer clinical advantages in terms of GI safety and unimpaired platelet function. CSIs do not offer advantages of renal safety over traditional NSAIDs. CONCLUSION Although CSIs display analgesic efficacy similar to that of traditional NSAIDs in the treatment of acute, post-oral surgery pain, there is reasonable evidence that these new drugs are preferable in patients who are at an increased risk of developing serious upper-GI complications, in patients who take aspirin for cardiovascular comorbid conditions, and in those allergic to aspirin. Furthermore, CSIs may be given more safely than NSAIDs in perioperative settings, because of their lack of impairment of the blood-clotting. However, the high costs of CSIs available at present limit their routine use in the short period of postoperative dental pain-in most cases 2 to 4 days after surgery-because there is not an increased risk of developing serious GI complications with the use of cost-saving NSAIDs. The GI safety advantages of CSIs may improve the tolerability of long-duration analgesic therapies, such as cases of painful temporomandibular joint disorders and chronic orofacial pain. Further studies are needed to determine the cost-benefit ratio of using CSIs for the management of acute pain.
