“…Morphologic, tapered, and doublestepped posts preserve dentin in the apical region of the post-space preparation, reducing the risks for root perforation (83). This is important for teeth with small tapered roots, such as maxillary lateral incisors and mandibular incisors (84). Teeth with short roots, large funnelshaped root canal orifices, and thin dentin walls present problems for post retention and the avoidance of root fractures, which morphologic cast posts cannot solve satisfactorily.…”

“…Among those factors are rotary NiTi instrumentation (Hin et al 2013), taper of the instrumentation files ), obturation Shemesh et al 2010), retreatment (Shemesh et al 2011;Topcuoglu et al 2014), post placement (Gluskin et al 1995), crosssectional shape of the roots (Gutmann 1992), high concentration of sodium hypochlorite (Shemesh 2015), age changes (PradeepKumar et al 2017), and parafunctional stresses (Cameron 1964). In this review, we will focus on the effects of instrumentation, obturation, and retreatments.…”

Root-originating dentinal defects: methodological aspects and clinical relevance

2017

It was in the 1980s when the association between root-filling procedures and dentinal microcracks was made. Nowadays, root-originating microcracks, also known as dentinal defects, are recognized as a possible precursor that is part of the longitudinal process of root-originating fractures. The presence of dentinal defects has been shown to significantly decrease the outcome through a periapical microsurgery model. Several in vitro articles have been published in the past years in regards to dentinal defects, but most of them have serious methodology concerns that will be discussed in this review. A total grasp of the development and the role dentinal defects play in endodontics is crucial to the specialty. This review aims to discuss dentinal defects and their causative factors and the research models that have been used and their clinical significance. Through a comprehensive critical review of the literature, this article will express the need for further in vivo clinical research and better ex vivo methods that can replicate the clinical setting to answer several remaining questions about the development of and the role dentinal defects play in endodontics.

“…Mandibular incisors generally have a ribbon-shaped root, with more thickness of dentin in the buccal lingual dimension and very thin dentin in the mesial-distal dimension. With a round post space preparation, therefore, there is risk of thinning or even perforating the mesial or distal root dentin (Gluskin et al 1995 ). Maxillary premolars with two roots also present an area of thin dentin on the furcal aspect of the buccal root (Lammertyn et al 2009 ), making the palatal root the more ideal location for a post.…”

Restoration of Root Canal-Treated Teeth

View full text Add to dashboard Cite

The aim of this chapter is to offer a guide, from the endodontist's perspective, as to how root canal-treated teeth should be restored, and to give some clinical recommendations to help meet these restorative goals. The endodontic and restorative components of treatment are typically considered as independent phases. However, when considering the impact of each of these phases on the long-term prognosis of the tooth, it becomes apparent that both the endodontic and restorative plans should be considered jointly before treatment is carried out. With so many options for the timing of treatment, endodontic and restorative materials, and restoration design, the clinician is left with some diffi cult decisions at the treatment planning phase. In this chapter, considerations for the material characteristics, restoration design, and management of post placement complications are presented and discussed with respect to their impact on longterm prognosis. In addition, treatment sequencing, techniques of temporization, and strategies to prevent coronal microleakage of endodontically treated teeth are discussed in detail.
