Residual Dental Pulp Tissue and Cord Blood Stem Cells
Irreversible PulpitisThe experiments outlined in this proposal are designed to test the hypothesis that the in vivo injection of cord blood stem cells (InvitRx®) into the root canal system will facilitate teeth initially diagnosed with irreversible pulpitis, to form normal healthy pulpal tissue.
Effect of Cryotherapy and LLLT on Postoperative Pain After Root Canal Treatment
Root Canal InfectionPain4 moreThe aim of this study is to evaluate the effect of low-level laser therapy (LLLT) and intracanal cryotherapy applications on postoperative pain in endodontic interventions of primary molar teeth with apical periodontitis. 75 patients were randomly assigned to the control, low-level laser and cryotherapy groups.Root canal treatments were performed in a single session. The pain intensity felt by the patients on the preoperative and postoperative 1st, 3rd, 5th and 7th days were recorded using the Wong Baker visual pain scale. Preoperative and postoperative 7th day percussion sensitivity was recorded using the VAS (visual analog scale) scale. The pain scores of the groups at different times after the procedure were compared. Statistical analysis of the data was performed at the 0.05 significance level.
Efficacy of Oral Prednisolone on Pain Reduction in Emergency Care of Acute Irreversible Pulpitis...
PulpitisIrreversible pulpitis is an inflammatory condition of the dental pulp, highly painful, representing one of the main reasons for consulting dental emergency. The recommended emergency care is a partial endodontic treatment under local and/or locoregional anesthesia. The purpose of the emergency partial endodontic treatment is to stop the pain of pulpitis by removing a portion of the pulp. The final endodontic treatment is ideally performed 72 hours after. The literature reports major difficulty in obtaining adequate anesthesia in the mandible to perform partial endodontic treatment, especially for the mandibular molars. This results in a very painful care for the patient. The management of this type of emergency is costly in terms of equipment and time for health facilities. Patient comfort, cost saving and rationalization of the care time justify the search for an alternative to emergency partial endodontic treatment. In current practice, the short course oral corticotherapy is used in the management of oral pain from inflammatory origin. Glucocorticoids, thanks to their anti-inflammatory action, can neutralize the inflammatory mediators and thus pain. The pulp inflammation can be treated with this molecule: the effectiveness of intraosseous local steroid injection for irreversible pulpitis of mandibular molars has already been shown but results in local comorbidities and requires specific device. Oral administration of short-course prednisolone is simple and safe but its effectiveness to manage pain caused by irreversible pulpitis has not yet been demonstrated. Per-os administration of prednisolone has a very high (90%) and rapid (≤ 4 hours) bioavailability. No difference in effectiveness between intravenous and oral administration of this molecule was reported. This oral treatment could limit comorbidities and technical difficulties related to intraosseous injection and could delay the endodontic treatment to 72 hours in optimal conditions of anesthesia for the patient. Despite the difficulties described for the partial endodontic treatment, it is very effective in pain reduction and can reach 100% of success. Therefore a non-inferiority design was chosen to compare the effect of a short-course oral corticotherapy to a partial endodontic treatment for the reduction of pain at the emergency care of the irreversible pulpitis in mandibular molars. The intervention arm will receive an oral dose of prednisolone (1 mg/kg) during the emergency visit followed-up by one morning dose by day during three days and the reference arm will have partial endodontic treatment. Both groups will have planned complete endodontic treatment 72 hours after enrolment.
Effect of Low Power Laser in Tooth Pain Modulation Caused by Irreversible Inflammation
PulpitisAcute PainAnxiety, pain and discomfort are common stressful situations that occur during the dentistry practice, especially in the urgency endodontic practice. Studies have concluded that low intensity laser therapy is effective in treating pain. However, most studies have reported the low intensity laser therapy in chronic pain, few studies have shown its application on acute pain and none have evaluated the low intensity laser´s analgesic effect in acute pain of the pulp inflammation. Since the pulp tissue has the peculiar characteristic to be surrounded by dentin, in acute pulpits, the inflammatory reaction is more complicated than usual. Furthermore, during the inflammatory process, sometimes anesthesia is not always completely effective. Thus, this present study aims to evaluate whether previous therapy with low intensity laser could, by its analgesic effect, promote greater comfort especially to this type of patient. 60 patients with acute pulpits pain will be selected to this study (randomized and double-blinded) and they will be divided in 4 groups: Group 1 ( n=15) - Control Group; Group 2 (n=15) - Laser 1: 780 nanometers (nm); 40 milliwatts (mW); 4 seconds per point; 0.16 Joules/point; total irradiated points: 02; Group 3 (n=15) - Laser 2: 780nm; 40 mW; 40 seconds per point; 1.6 Joules/point, total irradiated points: 02; Group 4 (n=15) - Placebo group - Sham Laser Irradiation. The pain will be evaluated by a visual analogue scale (VAS) in 3 different times: initial pain, pain immediately after and 15 minutes after interventions (laser irradiation, or sham laser irradiation). After that, patients with acute pulp irreversible inflammation will be submitted to conventional endodontic urgency treatment. Data concerning the need of complimentary local anesthesia will be also taken into account. Data of different groups and times will be statistically compared.
Comparison of Preoperative Analgesics on the Efficacy of Inferior Alveolar Nerve Block.
Symptomatic Irreversible PulpitisThe purpose of this study is to see how preoperative oral diclofenac sodium, piroxicam, and tramadol affects inferior alveolar nerve block efficacy during root canal treatment of mandibular molars with symptomatic irreversible pulpitis. The proposed hypothesis is that the tested drug groups will improve the efficacy of inferior alveolar nerve block in comparison to the control group.

Symptomatic Irreversible PulpitisIntroduction: to evaluate the efficacy of inferior alveolar nerve block (IANB), Gow-Gates nerve block (GGNB), and their combination in patients with irreversible pulpitis. Methods: One hundred fifty subjects with irreversible pulpitis of a mandibular molar were selected. subjects randomly received two IANB injections or two GGNB injections or their combination of 1.8 mL 2% lidocaine with 1:100,000 epinephrine. Success was specified as no or mild pain on the basis of Heft-Parker visual analogue scale recordings up on the access cavity preparation or initial instrumentation. Data were analyzed by Kruskal-Wallis, and ANOVA tests.
