Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a retrospective cohort study with two specific aims. The first aim focuses on the treatment outcome of different VPT protocols in young permanent tooth. The second aim is to determine if MTA is a suitable material in VPT and related factors potentially influencing prognosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Unlike fully developed teeth, the root canal treatment of young permanent teeth is particularly complex and difficult due to its large apical opening, short root length and thin canal wall. In modern endodontics, vital pulp therapy (VPT), a biological based procedures designed to restore functional pulp-dentin complex and promote continued root development, has been considered as an alternative treatment modality. Mineral Trioxide Aggregate (MTA) has been recommended for uses in VPT with preliminary studies, showing promising results. However, lack of high level of evidence trials, inconsistent treatment protocols and follow-up periods, heterogeneous selection criteria, result VPT unreliable and difficult to reach a consensus on the efficacy of MTA. Therefore, we propose this retrospective cohort study with two specific aims. The first aim focuses on the treatment outcome of different VPT protocols in young permanent tooth. The second aim is to determine if MTA is a suitable material in VPT and related factors potentially influencing prognosis. Subjects for the study will be identified from patients who received VPT at the Department of Dentistry in the National Taiwan University Hospital from 1999 to 2014 and have returned for tooth follow up at least one year after treatment. Treatment outcomes will be judged by analyzing clinical and radiographic data, which will be evaluated by 3 independent dentists. The radiographs will be evaluated using a geometrical imaging program-NIH Image J, to calculate the percentage increase in root length and width. Statistical analysis will be applied using the SPSS program to assess the treatment's success rates at the various follow-up periods. The differences will be statistically analyzed performing chi-square test, Fisher exact test, and t-test, using a statistical significance at p\<0.05.
