简要总结
Root canal therapy (RCT) is a classical and effective treatment that is currently utilised in dental practice, offering high success rates for pulp and periapical diseases; however, teeth after RCT are susceptible to altered pulp defence and sensory function, even fractures, as a consequence of pulp loss. Furthermore, several studies have highlighted that the actual failure rate of standard root canal treatments performed in general practice is significantly higher than expected . Moreover, these treatments are lengthy and costly and are often subject to retreatment .Inherent in this procedure(rct) is loss of dental hard tissue and subsequent weakening of the treated tooth,making them more prone to fracture. Therefore, less invasive alternative strategies could be used to treat pulpitis, even when irreversible.
Murray et al. proposed the term "Regenerative endodontic treatment (RET)" in 2007, based on a tissue engineering concept (stem cells, biomimetic scaffolds, and bioactive growth factors). The 2016 American Association of Endodontists (AAE) guidelines formally defined RET as a collection of "biologically based procedures designed to replace damaged tooth structures, including dentine and root structures, as well as cells of the pulp-dentine complex"
详细描述
Mature permanent teeth with Irreversible Pulpitis have traditionally been managed with root canal treatment .However this procedure significantly reduces the survival rate of tooth. Acknowledging the inherent healing potential of an infection-free pulp, attempts have been made to use pulpotomy as a treatment modality in permanent teeth with complete root development exhibiting symptoms of irreversible pulpitis, where the radicular pulp is still healthy. Besides, the issues associated with coronal pulpotomy in permanent teeth are uncertainty on the pulpal status at the time of treatment, and lack of predictability. Moreover, there is a dearth of information in the literature that assesses the healing potential of pulp tissue in terms of clinical and radiographic outcomes in mature teeth with irreversible pulpitis.Regenerative endodontic therapy (RET) has attracted increasing attention with the development of tissue engineering. RET applies the concept of tissue engineering to achieve revascularization, innervation, and restoration of odontoblastic layers. Unlike root canal therapy, the disinfected canals are filled with vital tissue in RET rather than biocompatible, nonvital foreign materials. While several studies have explored the potential of pulp regeneration for infected teeth, most studies are limited to the treatment of immature necrotic teeth . For mature permanent teeth, the vital pulp is also of great importance in enhancing the immune system in root canals, promoting dentin deposition under chronic stimuli, and preventing discolouration. However, most of the reports of pulp regeneration in mature teeth are case reports or case series as mature teeth have fewer stem/progenitor cells, have narrower apical pathways for cell migration, and are more difficult to disinfect. Hence, it is of great urgency to develop an improved RET procedure to maximise the regeneration potential of mature teeth and extend the indications of RET.
