Active clinical trials for "Pulpitis"

Aim. To compare the outcome of preoperative administration of single-dose ketorolac, non-steroidal anti-inflammatory drug and placebo on postoperative pain in teeth with irreversible pulpitis and apical periodontitis.

This Trial evaluated the extent of pulp survival following pulpotomy in the permanent tooth pulp exposed by caries and identify potential risk factors for pulpal complications.

The aim of this study is to evaluate the clinical and histological pulp responses when MTA and a combined of MTA/PRF is used as pulp-capping agents after partial pulpotomy.

To evaluate in a comparative way the perception of the patient who comes with pain due to irreversible pulpitis in a tooth and who receives two types of treatment: complete pulpectomy (or control group) or pulpotomy (or experimental group). Prospective randomized and multicenter study. It will be carried out in 4 centers of similar socio-professional characteristics, with the same operative protocol. On a significant sample of emergency patients with a concrete clinical manifestation of symptomatic irreversible pulpitis, one type of intervention or another will be performed randomly. The data will be collected by means of a visual numeric scale (NRS). The null hypothesis is that both interventions provide the same reduction of pain in patients who present symptomatic irreversible pulpitis. All the patients who come to one of the private centers with irreversible pulpitis and who meet the defined criteria for inclusion and exclusion will be selected. The type of procedure that will be performed in the control group will be the complete removal of the pulp by means of a defined instrumentation technique, also called Pulpectomy. The procedure to be performed in the experimental group will be the removal of the pulp only at coronal level, also called Pulpotomy. The interventions will be assigned randomly and the "List Randomizer" (random.org) will be used for the randomization.

In deep carious lesions, presenting risk of pulp exposition, a treatment option is the partial caries removal of carious tissue followed by provisional restoration, while this approach is called indirect pulp capping. The aim of this double-blinding controlled randomized clinical trial is to evaluate the success of indirect pulp capping using only resin-modified glass ionomer, while the additional layer of calcium hydroxide was used as control. The sample of 112 molars and/or premolars (n=56), presenting deep carious lesions, from patients with age between 15 and 30 years treated in dental clinic at Department of Dentistry of Federal University of Sergipe. The selected carious lesions must be reached 2/3 of dentin, observed in bite-wing radiography, without pulp involving and/or other factor that to compromise the evaluation. After detailed anamneses, the selected teeth will be radiographed e all carious tissue from surrounding walls will be removed. At the floor of cavity, the carious tissue will be partially removed using hand dentin excavators, remaining the caries-affected dentin and avoiding the pulp exposition. The removed carious tissue from the floor of cavity will be evaluated for presence of Lactobacilos e Estreptococos Mutans, while the remaining dentin will be evaluated for consistency, colour and humidity. Randomly, the cavity will be provisionally restored with: Control - dress and cement of calcium hydroxide followed resin-modified glass ionomer; or Experimental - only resin-modified glass ionomer. The distance between the base of restoration and the pulp cavity cap will be measured by bitw-wing radiography. The patients will be re-evaluated after 15 days, while the teeth with compromised pulp vitality will be excluded from the study. The remaining patients will be evaluated after 6 months. The distance between the base of restoration and the pulp cavity cap will be measured again, followed by provisional restoration removal. The remaining caries-affected dentin from floor of cavity will be fully removed and a bacteriological evaluation performed. The consistency, colour and humidity of this tissue will be evaluated too. Finally, the permanent restorations will performed.

Aim The aim of this clinical study was to evaluate the influence of the instrumentation techniques on the incidence and intensity of postoperative pain in single-visit root canal treatment. Methodology Ninety patients with single root/canal and non-vital pulps were included. The patients were assigned into 3 groups according to root canal instrumentation technique used; the modified step-back (stainless-steel hand files, HF), reciprocal (WaveOne, WO), and rotational (ProTaper Next, PTN). Root canal treatment was carried out in a single visit and the severity of postoperative pain was assessed by 4-point pain intensity scale. All the participants were called through phone at 12, 24 and 48 h to obtain the pain scores. Data were analyzed by the Kruskal-Wallis test.

Comparing the postoperative pain resulting after mechanical instrumentation using M-pro files versus that resulting after using ProTaper Next rotary files in lower molar with symptomatic Irreversible pulpitis molars.

The aim of this study is to evaluate the clinical and radiographic outcomes of Chitosan scaffold and Mineral trioxide aggregate (MTA) when used as pulpotomy agents in mature permanent teeth with irreversible pulpitis.

The aim of this randomized clinical trial was to compare the incidence, intensity and duration of postoperative pain following the removal of root canal obturation materials canals using rotary (ProTaper Universal or Hyflex EDM) or reciprocating file (Reciproc Blue or WaveOne Gold) systems. The null hypothesis tested was that there is no difference in postoperative pain following the retreatment procedure between the four systems used.

Aim: The purpose of this prospective, randomized, double-blind, controlled study was to compare the preoperative oral tramadol medication with ibuprofen and acetaminophen on the success of inferior alveolar nerve blocks (IANB) of mandibular posterior teeth in patients experiencing symptomatic irreversible pulpitis. Methodology: The study included five study groups, each consists of 50 patients who exhibited symptomatic irreversible pulpitis of a mandibular first or second molar. The patients received identically appearing capsules containing either tramadol 50 mg, tramadol 100 mg, ibuprofen 600 mg, ibuprofen 600 mg/acetaminophen 1000 mg or placebo by mouth 60 min before the administration of an IANB. Endodontic access was begun 15 min after completion of the IANB, and all patients used for data analysis had profound lip numbness. The IANB success was defined as no or mild pain (visual analog scale recordings) on pulpal access or instrumentation. The data were analysed using chi-square χ2 and Kruskal-Wallis tests.
