Introduction

In a dental practise , it is frequently difficult to restore devitalised anterior teeth , as it poses several challenges . The dentist should be able to judge from clinical experience and training to the extent to which a tooth that is non-vital and fractured can be restored and contribute to the oral health of the patient . Several

factors that exist or operate in the mouth need to be taken into consideration Sometimes , a tooth that may not cause any serious problem if restored may prove to serve an important functional asset in the mouth . In such cases , it would be very unwise to remove such a tooth . The dentist should also not consider that in every case a tooth , which is fractured and devitalised , could be restored . In every case , the factors that could play an important role in the outcome of such treatment should be determined . It is important that the tooth has good periodontal support . Besides , the restoration made should also be appropriate

Frequently , dentists would like to treat the tooth endodontically and then plan of how the tooth should be restored . However , the dentist should be able to decide the restorative treatment before the tooth is treated endodontically . In case of great number of difficulties , it may be necessary to extract the tooth , and in such cases endodontic post and core may not seem feasible . The dentist should also consider that newer materials and techniques have come out , which has made the process of restoring a tooth with post and core much more easier , and which has also resulted in improving the outcome . When a post is placed into an endodontically treated tooth , it is able to support a core . This core would serve as a base or a foundation for the restorative material . It would not be providing any kind of reinforcement (Charbeneau , 1989 The post and core restoration consist of several components , namely , the post , core , external restoration and the luting cement . The post and core system should posses certain characteristics , which would ensure that the tooth functions appropriately . This would also prove to be a huge benefit of the individual 's oral health . For a post and core restoration to be successful , it should have a good design and use appropriate restorative materials . Besides , the preparation should be made keeping technical considerations in mind . The restoration should have a retentive form and a resistance form . In anterior teeth , it is important that the restoration is aesthetically appropriate and if there is a need to retreat the tooth , considerations should be incorporated (ADA , 2006

Restoring endodontically treated teeth

There may be several problems whilst restoring endodontically treated teeth . When tooth become non-vital , they may get dehydrated and hence become more brittle . They may break when minimal pressure is applied...
