Management of Discolored Failure Root Canal-Treated Upper Lateral Incisor

Case Reports in Dentistry

Root canal treatment failure can be determined based on a patient’s complaint and on the basis of clinical examination and radiographic findings. Most of the signs and symptoms for the failure are pain and discomfort, swelling and sinus formation at the surrounding soft tissue, and discoloration of the subjected tooth. Factors such as mechanical perforation during the procedures, overfilled or underfilled root canal, and missed or unfilled canals are the main factors for the failure outcome. This case report presents a discolored and infected upper lateral incisor which was previously root canal treated. The tooth was successfully managed under nonsurgical and surgical retreatment followed by an internal bleaching and full porcelain veneer. Apical tissue healing and acceptable tooth appearance was observed during a 12-month review.

Coronal Tooth Discoloration and White Mineral Trioxide Aggregate

Journal of Endodontics, 2013

Introduction: This study assessed and characterized discoloration when white MTA (wMTA) was placed in the coronal aspect of the root canal ex vivo and the influence of red blood cells on this discoloration. Methods: Canals were prepared from the apical aspect and restored with either wMTA + saline (n = 18), wMTA + blood (n = 18), or controls (n = 4 + 4) (blood or saline alone). Color was assessed according to the CIE L*a*b* color space using standardized digital photographs at 3 time points: baseline, day 1, and day 35. Statistical analysis was performed by using 1-way analysis of variance and a 2-sample t test with P < .05. Results: All teeth discolored when restored with wMTA, which was most prominent in the cervical third of the crown. The presence of blood within the canal adjacent to the setting wMTA exacerbated the discoloration (P = .03). Conclusions: wMTA induces the gray discoloration of the tooth crown, and the effect is compounded in the presence of blood.

Bleaching of a Discolored Tooth with Retrieval of Remnants after Successful Regenerative Endodontics

Journal of Endodontics, 2018

Introduction: This report presents the retrieval of remnants from a discolored mandibular right second premolar (tooth #29) of a 17-year-old female after a successful regenerative endodontic procedure (REP). Methods: The REP was performed in October 2011. Coronal discoloration became of great concern to the patient at a review visit in 2016. A cone-beam computed tomographic scan was taken to investigate the formation of hard tissues within the root canal as well as a region of no calcified tissue formation. During internal bleaching of tooth #29, a black material with particulate inclusions was retrieved and examined histopathologically. Results: Five years after the REP, there was complete periapical healing, hard tissue formation within the root canal, and complete maturation of the root apex. A hard tissue bridge was noted at the cementoenamel junction when the pulp chamber of #29 was reaccessed. The remnants retrieved from the pulp chamber were confirmed to be partly mineral trioxide aggregate (MTA). A normal tooth color was achieved after 3 weeks of internal bleaching. Conclusions: MTA remnants within the pulp chamber contributed to the tooth discoloration and appear to have obstructed hard tissue formation. A matrix of oxidized regenerated cellulose seems not to hinder tissue regeneration and is resorbed by these tissues. Other materials with color stability should be selected as coronal barriers for REPs to avoid a potential adverse effect of the MTA on the REP outcome and discoloration.

Conservative esthetic management of post orthodontic treatment discolored tooth with calcified canal: a case report

The Pan African Medical Journal, 2020

A case of pulp canal obliteration (PCO) two years after the completion of orthodontic treatment is presented. Post orthodontic treatment PCO is a rare finding. A 23 years old female presented with the discoloration of clinical crown of maxillary right central incisor. Radiographic examination revealed the calcified canal and diffused periapical radiolucency. Vitality tests were negative. A decision was made to do root canal treatment followed by the walking bleaching. After the successful completion of the root canal treatment the internal bleaching was performed. The discolored tooth showed significant improvement in color. Internal bleaching is a viable conservative treatment for improving esthetics in single non vital discolored tooth.

Bleaching of Non Vital Anterior Tooth, Noninvasive Technique: A Case Report

Discoloration of the anterior tooth, can result in considerable cosmetic detriment in patients. Treatment of such cases pose challenge for the dental practitioners. A variety of treatment options for discolored non vital teeth are bleaching, crowns or veneers. Bleaching offers a simple and conservative approach in removal of intrinsic stain. This article describes a case of non vital bleaching which was performed on a root canal treated tooth with no reversible discoloration or cervical root resorption.

Nonvital Tooth Bleaching: A Review of the Literature and Clinical Procedures

Journal of Endodontics, 2008

Tooth discoloration varies in etiology, appearance, localization, severity, and adhesion to tooth structure. It can be defined as being extrinsic or intrinsic on the basis of localization and etiology. In this review of the literature, various causes of tooth discoloration, different bleaching materials, and their applications to endodontically treated teeth have been described. In the walking bleach technique the root filling should be completed first, and a cervical seal must be established. The bleaching agent should be changed every 3-7 days. The thermocatalytic technique involves placement of a bleaching agent in the pulp chamber followed by heat application. At the end of each visit the bleaching agent is left in the tooth so that it can function as a walking bleach until the next visit. External bleaching of endodontically treated teeth with an in-office technique requires a high concentration gel. It might be a supplement to the walking bleach technique, if the results are not satisfactory after 3-4 visits. These treatments require a bonded temporary filling or a bonded resin composite to seal the access cavity. There is a deficiency of evidence-based science in the literature that addresses the prognosis of bleached nonvital teeth. Therefore, it is important to always be aware of the possible complications and risks that are associated with the different bleaching techniques. (J Endod 2008; 34:394 -407)

Management of Non-Vital Teeth Discoloration with the Internal Bleaching : A Case Report

Indian Journal of Forensic Medicine & Toxicology

Tooth discoloration due to intra coronal bleeding after trauma can cause aesthetic disturbances and appearance. Internal bleaching is a non-invasive method to restore tooth color which is performed after endodontic treatment by placing a strong oxidizing agent in the pulp chamber. Aim of this study was to report the success of internal bleaching procedure to restore discolored teeth due to trauma. A 44-year-old female came to Conservative Dentistry Universitas Airlangga with chief complaint of the upper right insisor tooth looks darker than the adjacent teeth. The patient had fallen 10 years ago from her motorcycle and her tooth had been painful and then the pain disappeared. In intra oral clinical examination, it showed that tooth 11 had discoloured, vitality test of tooth 11 showed no response to electric pulp test. Radiographic view showed that radiolucen in periapical area and no fracture was found. At the first visit, treatment of single visit root canal using rotary instrument and gave dressing calcium hydroxide. A week later on the second visit, internal bleaching with hydrogen peroxide 35% was done. After bleaching, calcium hydroxide was applied to neutralize the oxidizing agent and then re-evaluated for the color. At the third visit, it showed that the tooth colour was obtain as desire from C3 to A3 (Vitapan Classical). The internal bleaching procedure on the traumatized tooth was the best option to restore the function and aesthetics according to the original tooth colour and also provided benefits in terms of saving time, lower price, and maximum results.
