Mineral trioxide aggregate as a pulpotomy agent in primary molars: an in vivo study. (1/16)
The retention of pulpally involved deciduous tooth in a healthy state until the time of normal exfoliation remains to be one of the challenges for Pedodontists. A scientific noise has been generated about several materials some of which have been popular pulpotomy medicaments. Concerns have been raised about the toxicity and potential carcinogenicity of these materials, and alternatives have been proposed to maintain the partial pulp vitality, however to date no material has been accepted as an ideal pulpotomy agent. Mineral trioxide aggregate (MTA) is a biocompatible material which provides a biological seal. MTA has been proposed as a potential medicament for various pulpal procedures like pulp capping with reversible pulpitis, apexification, repair of root perforations, etc. Hence the present study was done to evaluate the efficacy of MTA as a pulpotomy medicament. A clinical and radiographic evaluation was done on children where MTA was used as pulpotomy medicament in primary molars for a period of 6 months and it was found to be a successful material.

The studies so far conducted by our colleagues in relation to dental pulp capping using adhesive resins revealed that the adhesive resins are useful for capping exposed pulps but are a little slower to take effect on the injured pulp tissue during the initial stage: up to 90-days after pulp exposure, compared with calcium hydroxide and its preparations. In the present study, an experimentally developed adhesive resin system was applied in direct pulp capping and restoration and the healing process was examined histopathologically and immunohistochemically. The resin system was manufactured with calcium phosphate added into the bonding material for the purpose of accelerating the healing process. The largest amount of reparative dentin was formed by SE5 (whitlockite 5 wt%), followed by SE9 (hydroxyapatite 5 wt%, whitlockite 5 wt%), SE1 (hydroxyapatite 5 wt%), and SE2 (hydroxyapatite 10 wt%). Generally, it could be said that the experimental groups using whitlockite and hydroxyapatite had the tendency to produce a larger amount of reparative dentin.

The aims of this study were to investigate the release of fluocinolone acetonide from an experimental pulp capping material containing fluocinolone acetonide (PCFA) and compare some physical and mechanical properties with Dycal((R)). The PCFA is a hard-setting calcium hydroxide cement composed of 50 mmol/L fluocinolone acetonide. Conditioned media from the setting material was collected for determination of fluocinolone acetonide release by high performance liquid chromatography and pH measurement by pH meter. The setting time, compressive strength, disintegration, and acid soluble arsenic content were measured according to ISO 3107:2004. Dycal((R)) was used as control. Fluocinolone acetonide could release at a range of suitable concentrations from PCFA. The pH, setting time, and acid soluble arsenic content of PCFA were significantly higher than those of Dycal((R)). The compressive strength and disintegration of PCFA were comparable to control. PCFA may be considered as an alternative in pulp capping of inflamed dental pulp tissue.

(+info)A pulpectomy is a dental procedure that involves the removal of the entire pulp tissue, which includes the nerves, blood vessels, and connective tissues from within the root canal(s) of a tooth. This procedure is typically performed when the pulp tissue becomes infected or inflamed due to decay, trauma, or other causes.
Once the pulp tissue is removed, the root canal(s) are cleaned, shaped, and filled with an inert material such as gutta-percha to prevent reinfection and maintain the structural integrity of the tooth. A pulpectomy may be performed as a standalone procedure or as part of a larger treatment plan, such as a root canal therapy or endodontic treatment.
It's important to note that while a pulpectomy removes the infected or inflamed tissue from within the tooth, it does not address any external damage or decay that may be present on the tooth's surface. Additional dental work, such as a filling or crown, may be necessary to restore the tooth's function and appearance.
Pulp capping is a dental procedure that involves the application of a small amount of dressing to a small exposed area of the pulp in order to promote healing and maintain the vitality of the pulp. The agents used for pulp capping are known as pulp capping agents, which typically include calcium hydroxide-based materials and mineral trioxide aggregate (MTA). These materials stimulate the formation of a hard tissue barrier between the pulp and dentin, protecting the pulp from infection and further injury.
Pulpectomy, on the other hand, is a dental procedure that involves the complete removal of the pulp tissue from the root canal system. After the removal of the pulp tissue, the root canal system is cleaned, shaped, and filled with a suitable filling material to prevent reinfection and maintain the structural integrity of the tooth.
Pulpectomy agents are the materials used during the pulpectomy procedure to clean, shape, and fill the root canal system. These agents may include irrigants such as sodium hypochlorite or chlorhexidine, files and reamers for shaping the root canal system, and filling materials such as gutta-percha and root canal sealers. The choice of pulpectomy agents depends on various factors, including the size and shape of the root canal system, the presence of any infection or inflammation, and the patient's individual needs and preferences.
Periapical tissue, in the field of dentistry and oral medicine, refers to the tissue that surrounds the apical region of a tooth. The apical region is the tip or apex of the root of a tooth. Periapical tissues include the periodontal ligament, the alveolar bone, and the dental follicle. These tissues play a crucial role in supporting and protecting the tooth. Inflammation or infection of the periapical tissue can lead to a condition known as periapical periodontitis, which may require root canal treatment or tooth extraction.
Dental pulp capping is a dental procedure that involves the application of a small amount of medication or dressing to a small exposed area of the dental pulp, with the aim of promoting the formation of reparative dentin and preserving the vitality of the pulp. The dental pulp is the soft tissue located inside the tooth, containing nerves, blood vessels, and connective tissues that provide nutrients and sensory functions to the tooth.
Pulp capping may be recommended when the dental pulp is exposed due to tooth decay or trauma, but the pulp is still vital and has the potential to heal. The procedure typically involves cleaning and removing any infected or damaged tissue from the exposure site, followed by the application of a medicated dressing or cement to promote healing and protect the pulp from further injury or infection.
There are two types of pulp capping: direct and indirect. Direct pulp capping involves applying the medication directly to the exposed pulp, while indirect pulp capping involves placing the medication over a thin layer of dentin that has been created to protect the pulp. The success of pulp capping depends on various factors, including the size and depth of the exposure, the patient's age and overall health, and the skill and experience of the dental professional performing the procedure.
