Active clinical trials for "Dental Pulp Diseases"

Total amputation therapy; is a treatment method aimed at maintaining the vitality of the radicular pulp remaining as a result of complete removal of coronal pulp tissue. In cases where pulp is exposed due to caries or trauma, the pulp is vital, bleeding can be controlled during the procedure, no periapical pathology is seen and radicular pulp is healthy. Traditionally, acute pulp pain is thought to be a symptom of irreversible pulpitis, and it is thought that there is little chance of the pulp returning to its normal situation after removal of the irritants. Root canal treatment has been accepted as the gold standard for the treatment of these symptoms. In recent studies, spontaneous or severe pain before procedure has not always indicated that pulp has no repair capacity, and deep carious lesions are not necessarily associated with irreversible pulpal pathology. Histological studies showed that even when caries reach the pulp or degeneration and inflammation were seen in it, there was a healthy section still present in the pulp. Therefore, it is stated that the healthy pulp remaining as a result of total amputation performed by removal of degenerated pulp can be preserved. Furthermore, it is stated that for the healing potential of the remaining pulp tissue, the original signal should be that the bleeding can be controlled after the amputation of the infected pulp tissue. While the most popular method in the treatment of vital pulp is CaOH, the American Academy of Pediatric Dentistry has been reported to be more resistant to dissolution in the protocol in recent years. MTA is a more suitable material because it is more homogeneous, and forms a thicker dentin bridge. However, the MTA requires a long time to harden, it is difficult to manipulate and color. In recent years, researchers have focused on creating new MTA formulations to improve their physicochemical properties without affecting their biocompatibility and bioactivity. NeoMTA Plus is a new fine powder tricalcium silicate. It consists of a water-based gel and powder mixture and the powder-gel mixing ratio may vary depending on the area of use. It is a material similar to MTA Plus. However, in order to avoid tooth discoloration, tantalium oxide used instead of the bismuth oxide and required calcium hydroxide used to induce the formation of mineralized tissue.

In this study, the aim is to compare manual and rotatory pulpectomy techniques on 100 primary mandibular molars on children between the ages of 4 and 8 years. The plan is to conduct a randomized controlled trial with a 1:1 ratio for group allocation at a teaching university pediatric dentistry clinic between January 2021 and December 2021. Two manual systems, as well as two rotary systems, will be randomly assigned. The adult manual system used will be K-file and the adult rotary system will be K3. The pediatric manual system used in this study will be Kedo-SH, while the pediatric rotary system will be Kedo-S. The observed outcome measures in this study are the following: 1) instrumentation and filling time; 2) filling quality by radiographic evaluation; 3) postoperative pain levels using the visual analog scale at 12 and 24 hours; and 4) frequency of complications (e.g. fistulas, thinning of the mesiodistal walls, periapical or furcation radiolucency) after a 3-, 6-, 9-, and 12-month follow-up.

Mineral trioxide aggregate has been previously FDA approved as an endodontic filler. Its use in vital teeth has demonstrated significant color change post-treatment leaving it ineffective for esthetic use.. The new formulation will be tested to see if has the same effect.

The purpose of this study is to evaluate the long term clinical performance of vital pulp therapy of young permanent teeth with irreversible pulpitis

Pulp re-vascularization/regeneration is a procedure performed to allow pulpal stem cells to survive and/or differentiate to allow immature tooth root structures to grow to full maturity. Currently, the procedure includes disinfection of the necrotic root canal space and induction of bleeding to potentiate pulpal stem cell differentiation to allow root growth on an immature root. A number of studies conducted previously demonstrate that N-acetyl cysteine (NAC) potentiates differentiation of pulpal stem/stromal cells and protects pulpal cells from apoptosis. 14-18 human subjects will be recruited forming two groups where pulp re-vascularization/regeneration procedures will be performed with or without the use of NAC treatment prior to induction of bleeding. Recall follow-up appointments will be done at 6 months and 1 year post treatment with subsequent yearly appointments until full root growth has been achieved.

Formocresol (FC) is the most universally taught and most widely used pulpotomy medicament in the primary teeth. However, concerns have been raised over the use of FC because of its toxicity and potential carcinogenicity. A substitution for FC has been investigated but evidence is lacking to conclude which is the most appropriate technique for pulpotomies in primary teeth. Sodium hypochlorite (NaOCl) has been used in root canal irrigant for more than 80 years, and it is at present the most popular irrigant in root canal treatment. Studies have showed that NaOCl is biological compatible and is a very good antimicrobial solution without being a pulpal irritant. Recent studies using sodium hypochlorite as pulpotomy medicament in primary molars showed promising results. In this project, the investigators propose a randomized clinical trial, which will be performed in Pediatric Dentistry Department of the National Taiwan University Hospital, to compare the treatment outcomes between NaOCl and FC in human primary molars needing pulpotomy treatment. The aim of this sudy is to determining weather NaOCl is a suitable replacement for FC in the pulpotomy of human primary molar teeth. To assess this aim, 200 healthy children from 2.5 to 9 year-old, who have at least one primary first or second molars diagnosed to receive pulpotomy treatment will be recruited in this project. The involved teeth will be randomly assigned to the control group (dilute 20% Formocresol (DFC)) or experimental group (2.5% NaOCl). At 3, 6, 9, 12, 15, 18, 21 and 24 months post-treatment, the randomly assigned teeth will be clinically and radiographically evaluated by blinded independent evaluators to the treatment group. The differences will be statistically analyzed using chi-square test, Fisher exact test, and t-test, using a statistical significance at p<0.05.

The main goal of root canal treatment is the removal of existing microorganisms and the prevention of introducing new ones to the root canal system. This will require the application of strict aseptic measures. Microorganisms may also find their way into the root canal system through dental materials and instruments that are used during the treatment. Some studies have suggested the necessity of decontamination of these materials and instruments prior to using. Also, the practice of changing gloves and disinfecting the tooth and rubber dam may help to reduce the possibility of introducing bacteria into the root canal space. This study is aimed to evaluate the success rate of initial root canal treatment using an enhanced sterility protocol.

The patients will be randomly assigned into two equal groups Group : OneShape Group: ProtaperNext Endodontics procedure steps: Patient will be anesthetized by using infiltration local anesthesia or nerve block according to the tooth location in mandibular or maxillary arch respectively. All caries will be removed, then isolation using rubber dam, the crown and surrounding structures will be disinfected with 30% H2O2( hydrogen peroxide) for 30 seconds, followed by 2.5% NaOCl for the same period of time and then inactivated with 5% sodium thiosulphate. 2- For the access cavity preparation, a sterile/apyrogenic high-speed diamond bur will be used in conjunction with manual irrigation with sterile saline. Before entering the pulp chamber, the access cavity will be disinfected according to the protocol described above. 2- Root canal length will be determined, by preoperative radiograph then (S1) will be taken by introducing a sterile/apyrogenic paper point #15/ 20 (5paper points) into the full length of the canal and left there for 1 minute. Then, the sample will be placed in an apyrogenic glass and stored in -20°. Then canal length will be confirmed by apex locator. 3- Cleaning and shaping will be done using either One shape or Protaper next rotary instruments in crown down preparation technique with the use of in an endodontic motor according to the manufacturer instructions, the canals will be thoroughly irrigated using 3ml of 2.5% Sodium hypochlorite between every subsequent instrument.
