简要总结
The purpose of this RCT is to compare the clinical/radiographic outcomes of Potassium nitrate in polycarboxylate cement and MTA as pulpotomy biomaterials used for asymptomatic vital immature permanent lower first molar and this will help to clinically evaluate the use of alternative capping material in vital pulpotomy in young permanent teeth with pathologic pulpal injuries emphasis is set on avoiding total pupectomy and maintaining radicular pulp vitality and function and therefore maintain the tooth in a viable condition that help root completion.
详细描述
introduction: Vital pulp therapy (VPT) is defined as a treatment which aims to preserve and maintain pulp tissue that has been compromised but not destroyed by caries, trauma, or restorative procedures in a healthy state. Pulpotomy is one of the techniques of VPT where unhealthy pulp in pulp chamber is amputated leaving the healthy one in radicular part in root canal. This is particularly important in the young adult tooth with incomplete apical root development.
An important benefit for preservation of vital pulp is the protective resistance to mastication forces compared with a root-canal-filled tooth. It is reported that the survival rate of endodontically treated teeth is not as good as vital teeth especially in molars.
VPT is primarily recommended to be performed in young patients because of the high healing capacity of pulp tissue compared to older patients. The presence of an adequate blood supply is required for the maintenance of the pulp vitality. In addition, the presence of a healthy periodontium is necessary for success of VPT, where teeth with moderate to severe periodontal disease are not suitable candidates for the treatment.The prognosis of VPT is significantly reduced in cases with inadequate coronal seal and subsequent bacterial microleakage.
One of the most important issues in VPT is the status of the pulp tissue. The traditional school of thought is that VPT should only be carried out in teeth with signs and symptoms of reversible pulpitis.
After amputation of coronal pulp tissues Control of hemorrhage is also necessary for the success of VPT. Various options are available for the achievement of pulp hemostasis such as mechanical pressure using a sterile cotton pellet which may be soaked in sterile water, sodium hypochlorite and saline. Cases with signs of prolonged bleeding for more than 5 minutes are not candidates for pulpotomy.
