1. Introduction

Dentists frequently face the predicament of whether to endodontically treat a dubious tooth

or to replace it with an implant. Dentists make the decision for extracting a tooth based on

risk factors such as periodontal and endodontic criteria, remaining tooth structure, size of

previous restorations and the strategic level of a tooth within the dentition. A single

recognizable risk can be easy to manage clinically, but presence of multiple risk factors

endanger the survival of a compromised tooth.[114][156]

Literary data are the foundation for the risk evaluation and long-term prognosis

determination of the tooth requiring root canal treatment (RCT) or extraction and

replacement with an dental implant. The literature, contains contradiction in terms of the

meaning of success and survival of endodontically treated teeth and implants.[70]

Likewise, the reported success rates do not equate to the likelihood of a aid and abet

outcome when applied to a special case.[73]

Iqbal and Kim found that much more rigorous outcome criteria were applied to the

evaluation of ‘successful’ RCT, inclusive the lack of a periapical radiolucency. On the other

hand, the use of less rigorous criteria in dental implantology may interpret to higher rates

of success.[70]

In accordance with a review, the survival of healthful and treated teeth is greater than that

of implants, provided that dental implant loss before loading was added to that during

function over 10 years.[56]

Additional misunderstanding is provoked since, in some studies, retention or survival rates

including successful teeth and also implants classified as surviving. The reader in implant

studies must know the differences in outcome data based on the restoration or implant

level, which involves superstructures and Implants.[113]

Commonly when a failure occure in endodontically treated tooth, some potentially

problems for implant placement can occure due to the residual pathology. Problems like

bone resorption ora damage of bone due to infections needs bone grafting and

rexonstruction of soft-tissue.[90]

Its important to know that teeth with endodontic treatment have less complications than

implant-supported crowns, if an implant fails patient will have more negative significants

than in the case of failures in endodontically treated tooth.[96]

By choosing a treatment method the doctor has to keep in mind following points:

1. Restorative prognosis of the tooth

2. Physical loading characteristics

For example: in the case of a „post“ rebuild of tooth structure is needed to retain

restorations. In the case of root-filled tooth when retention is added it also increases the

risk of damaging the tooth structure.[19]

The lifetime of an implant compared to the natural tooth which is endodontically treated

and support a post and core is much higher to retain a crown.[121] Therefore, teeth which

are treated with posts have to be used in regions where they are used for example as

abutments for bridges.[32]

However there are some risks in the implant treatment such as periodontal comlications or

occlusal as well as esthetic problems. Comparing to implant-supported restorations, the

endodontic treatments have advantages such as proprioception and adaptation which are

mediated by the PDL under mechanical force.[145]

Teeth that are endoddontically treated have greater maximum bite force and efficiency of

chewing than implant-supported prostheses.[157]

The choice of the treatment to extract or retain a tooth which will affect the neighboring

teeth, especially those used as abutments is an important decision. In a study was

reported that in the case of removable partial denture which is used more than 10 years

the probability to loss the abutment is 44%.[5]

But there is not mentioned what happens to the bordering teeth when an implant is

inserted. In a big edentulous region a span of FPD is needed for extention for tooth

incorporation that need whether endodontically or peridontally therapies, which will

compromising the lifelong stability of prosthesis.[49] [10] [9] [121] [114]

34

If a tooth is decayed but not treated, it maight cause bone loss and make the dental

implantation more complex.[112] [54] [30] [88]

Placing an implant next to a tooth which is endodontically treated can be affected.

According to a suggestion of some researchers is better to prevent implantation in

positions where a tooth is clinically symptomatic (e.g. periapical pathology or radiographic

periapical pathology).Thereby its useful to extract the previously treated

neighboring tooth before implantation.[158]

However there are some researchers how have the suggestion that there is no effect on

implant prognosis if the adjacent tooth is endodontically treated
