“…These include but are not limited to the absence of an apical lesion, use of dental dams during treatment and core placement, use of surgical operating microscopes, periodontal condition, structural integrity/restorability of the tooth, biofilms, and effective post-endodontic restoration. 4,14,15,16,17,18,19,20,21,22 The endodontic literature is replete with research focused on these local factors, yet few articles have been published that focus on the effect of provider training on outcomes. Alley et al 23 found that endodontic treatment provided by endodontic specialists was more than 10% more successful than treatment provided by general dentists.…”

Introduction: The objective of this study was to compare the outcomes of initial nonsurgical root canal therapy for different tooth types provided by both endodontists and other providers. Methods: By using an insurance company database, 487,476 initial nonsurgical root canal therapy procedures were followed from the time of treatment to the presence of an untoward event indicated by Current Dental Terminology codes for retreatment, apical surgery, or extraction. Population demographics were computed for provider type and tooth location. KaplanMeier survival estimates were calculated for 1, 5, and 10 years. Hazard ratios for provider type and tooth location were calculated by using the Cox proportional hazards model. Results:The survival of all teeth collectively was 98% at 1 year, 92% at 5 years, and 86% at 10 years. Significant differences in survival on the basis of provider type were noted for molars at 5 years and for all tooth types at 10 years. The greatest difference discovered was 5% higher survival rate at 10 years for molars treated by endodontists. A hazard ratio of 1.394 was found when comparing other providers' success with that of endodontists within this 10-year molar group. Conclusions: These findings show that survival rates of endodontically treated teeth are high at 10 years after treatment regardless of provider type. Molars treated by endodontists after 10 years have significantly higher survival rates than molars treated by non-endodontists.

“…It is also reported that the restorative procedures were the greatest contributors to the loss of tooth stiffness. Surprisingly, endodontic procedures reduced tooth stiffness by only 5% through the access opening, while MOD cavity preparation reduced tooth stiffness by more than 60% [35].…”

“…A study carried out in vitro has shown that root canal treatment reduces cuspal stiffness by only 5%, whereas cutting a mesio-occlusal-distal (MOD) cavity reduces stiffness by 63% suggesting that root canal treatment per se does not weaken the tooth. 42 The decreased strength observed in root canal treated teeth is because of the loss of coronal tooth structure and not directly as a result of the endodontic treatment. There is a direct relationship between the amount of remaining tooth structure and the ability of a tooth to resist occlusal forces.…”

“…Minimal occlusal access preparations in otherwise intact teeth may be restored conservatively using composite resin which has been shown to improve tooth stiffness. 42 Teeth with existing restorations involving the marginal ridge or those with extensive loss of tooth structure require cuspal coverage restorations, either onlays or full coverage crowns. 47 Wherever possible posts should be avoided in posterior teeth as the roots are often narrow and/or curved and post space preparation can lead to a strip or lateral perforation.…”

Restoration of the root-filled tooth: pre-operative assessment

This is the first in a series of four papers related to the management of root canal treated teeth. When teeth compromised by extensive restorations become non-vital, suggestions have been given as to how root canal treatment can be carried out with the greatest chance of success. Once root canal treated, either by a previous dentist or by the current dentist, a review of the assessment process that should be carried out prior to placing costly indirect definitive restorations is given. It will be clear that post-retained restorations are mainly reserved for anterior or single-rooted teeth, posterior teeth rarely requiring a post for core retention. The second paper in this series describes the basic tooth preparation that should be carried out prior to placing a post. Depending on the type of post system used, further modifications to tooth preparation may be required and the cementation techniques may also have to be modified. The third paper therefore discusses the various post types, when and how they should be used for optimum results. The final paper addresses reinforcement and restoration of compromised root canals, such as those with immature, open apices, or those that have been over-prepared for previous post-retained restorations.
