Efficacy of orally administered prednisolone versus partial endodontic treatment on pain reduction in emergency care of acute irreversible pulpitis of mandibular molars: study protocol for a randomized controlled trial.

ABSTRACT: Irreversible pulpitis is a highly painful inflammatory condition of the dental pulp which represents a common dental emergency. Recommended care is partial endodontic treatment. The dental literature reports major difficulties in achieving adequate analgesia to perform this emergency treatment, especially in the case of mandibular molars. In current practice, short-course, orally administered corticotherapy is used for the management of oral pain of inflammatory origin. The efficacy of intraosseous local steroid injections for irreversible pulpitis in mandibular molars has already been demonstrated but resulted in local comorbidities. Oral administration of short-course prednisolone is simple and safe but its efficacy to manage pain caused by irreversible pulpitis has not yet been demonstrated. This trial aims to evaluate the noninferiority of short-course, orally administered corticotherapy versus partial endodontic treatment for the emergency care of irreversible pulpitis in mandibular molars.This study is a noninferiority, open-label, randomized controlled clinical trial conducted at the Bordeaux University Hospital. One hundred and twenty subjects will be randomized in two 1:1 parallel arms: the intervention arm will receive one oral dose of prednisolone (1 mg/kg) during the emergency visit, followed by one morning dose each day for 3 days and the reference arm will receive partial endodontic treatment. Both groups will receive planned complete endodontic treatment 72 h after enrollment. The primary outcome is the proportion of patients with pain intensity below 5 on a Numeric Scale 24 h after the emergency visit. Secondary outcomes include comfort during care, the number of injected anesthetic cartridges when performing complete endodontic treatment, the number of antalgic drugs and the number of patients coming back for consultation after 72 h.This randomized trial will assess the ability of short-term corticotherapy to reduce pain in irreversible pulpitis as a simple and rapid alternative to partial endodontic treatment and to enable planning of endodontic treatment in optimal analgesic conditions.ClinicalTrials.gov, identifier: NCT02629042 .

Project description:ObjectivesThe study aimed to assess the effectiveness of cryotherapy application after inferior alveolar nerve block (IANB) administration of the mandibular first permanent molars with symptomatic irreversible pulpitis (SIP) in adolescence. The secondary outcome was to compare the need for supplemental intraligamentary injection (ILI).Materials and methodsThe study was designed as a randomized clinical trial including 152 participants aged from 10 to 17 years who were randomly assigned to two equal groups; cryotherapy plus IANB (intervention group) and the control group (conventional INAB). Both groups received 3.6 mL of 4% articaine. For the intervention group, ice packs were applied in the buccal vestibule of the mandibular first permanent molar for 5 min. Endodontic procedures started after 20 min for efficiently anesthetized teeth. The intraoperative pain intensity was measured using the visual analogue scale (VAS). The Mann-Whitney (U) and chi-square tests were applied to analyze data. The significance level was set to 0.05.ResultsThere was a significant reduction in the overall intraoperative VAS mean in the cryotherapy group compared to that in the control group (p = 0.004). The success rate was significantly higher in the cryotherapy group (59.2%) compared to the control group (40.8%). The frequency of extra ILI was 50% and 67.1% in the cryotherapy and control groups, respectively (p = 0.032).ConclusionsThe cryotherapy application boosted the efficacy of pulpal anesthesia of the mandibular first permanent molars with SIP in patients below the age of 18 years. Additional anesthesia was still necessary for optimal control over pain.Clinical relevancePain control during endodontic treatment of primary molars with irreversible pulpitis (IP) is a significant factor in a child's behavior in the dental office. Although the inferior alveolar nerve block (IANB) is the most commonly used technique to anaesthetize mandibular dentition, we found its success rate to be relatively low during endodontic treatment of primary molars with IP. Cryotherapy is a new approach that significantly improves the efficacy of IANB.Clinical trial registrationThe trial was registered at ClinicalTrials.gov (reference no. NCT05267847).

Project description:BackgroundIrreversible pulpitis is a highly painful inflammatory condition of the dental pulp. The recommended care is the removal of the coronal pulp (pulpotomy) for emergency treatment in multi-rooted teeth. However, achieving adequate analgesia in the case of mandibular molars presents many difficulties according to the dental literature. Intraosseous computerised anaesthesia (ICA), in particular, the QuickSleeper™ system, has already been demonstrated to be clinically efficient, but ICA is known to increase the heart rate reversibly in a manner that depends on the speed of injection. Therefore, accelerated heart rate was examined as a potential adverse effect of this injection. This trial aims to compare the cardiovascular effects and the anaesthetic efficacy of ICA versus inferior alveolar nerve block anaesthesia (IANB) in acute irreversible pulpitis of mandibular molars.MethodsThis study is a non-inferiority prospective, randomised, controlled, single-blind, two-group trial conducted at the Nantes University Hospital. The study design included two parallel arms at a ratio of 1:1 that will allocate seventy-two patients into two groups: the first group will receive QuickSleeper™ intraosseous anaesthesia; the second will receive an inferior alveolar nerve block before emergency treatment (pulpotomy). This study will include patients requiring emergency dental care under local anaesthesia with confirmed irreversible pulpitis in mandibular molars. The primary outcome is the time taken for the fluctuations in the cardiovascular parameters to return to baseline values during endodontic treatment in two different anaesthetic techniques. The secondary outcomes include efficacy of the technique, patient's pain perception before and after care, any post-operative effects, and factors associated with the delay of recovery of cardiovascular parameters between the 2 anaesthetic techniques.DiscussionThis trial will evaluate the factors associated with heart rate increase during local anaesthesia administration. The use of blood pressure and cardiovascular measurements can be considered an asset and additional safety in managing local anaesthesia. Detecting early signs of potential adverse events (AEs), particularly patients with certain medical conditions (cardiac rhythm disorders), would suggest caution in administering anaesthesia.Trial registrationClinicalTrials.gov ID: NCT03802305 registered January 14, 2019.

Project description:BackgroundMechanosensitive ion channel PIEZOs have been widely reported to involve inflammation and pain. This study aimed to clarify expression patterns of PIEZOs and their potential relations to irreversible pulpitis.Materials and methodsNormal pulp tissues (n = 29) from patients with impacted third molars and inflamed pulp tissues (n = 23) from patients with irreversible pulpitis were collected. Pain levels were assessed using a numerical rating scale. PIEZO expressions were measured using real-time PCR and then confirmed using GEO datasets GSE77459, immunoblot, and immunohistochemistry staining. Correlations of PIEZO mRNA expression with inflammatory markers, pain markers, or clinical pain levels were evaluated using Spearman's correlation analysis. Univariate analysis was conducted to analyze PIEZO expressions based on pain description and clinical examinations of cold test, percussion, palpation, and bite test.ResultsCompared with normal pulp tissues, mRNA expression levels of PIEZO1 were significantly increased in inflamed pulp tissues, while PIEZO2 was significantly decreased, which was further confirmed in GSE77459 and on a protein and histological level. The positive correlation of the mRNA expression levels between PIEZO1 and inflammatory markers, as well as between PIEZO2 and pain markers, was verified. PIEZO2 expression was also positively correlated with pain levels. Besides, irreversible pulpitis patients who reported continuous pain and who detected a positive response to cold stimulus exhibited a higher expression level of PIEZO2 in the inflamed pulp tissues. By contrast, patients reporting pain duration of more than one week showed a higher expression level of PIEZO1.ConclusionsThis study demonstrated the upregulation of PIEZO1 and the downregulation of PIEZO2 in irreversible pulpitis and revealed the potential relation of PIEZO1 and PIEZO2 to inflammation and pain. These findings suggested that PIEZOs might play critical roles in the progression of irreversible pulpitis and paved the way for further investigations aimed at novel therapies of irreversible pulpitis by targeting PIEZOs.
