1/23. Thermal sensitivity of endodontically treated teeth.case reports: The problem of thermal sensitivity following non-surgical root-canal treatment is explored and case reports are presented. Possible causes for post-treatment discomfort from endodontic and restorative aetiologies are discussed, as are the mechanisms to explain the patients' painful experiences. Treatment of this problem may vary from the simple replacement of a defective restoration to a more extensive non-surgical retreatment of the case, despite radiographic evidence of an acceptable root filling and normal periradicular tissues.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
2/23. Apical bridging in association with regular root formation following single-visit apexification: a case report.A case report is presented in which continuing root formation occurred in a carious nonvital and immature mandibular second premolar after single-visit calcium hydroxide apexification treatment. An apical hard tissue barrier was formed, accompanied by a separate, mesioapically growing root, 7 months posttreatment. Treatment was concluded with gutta-percha root canal restoration. The success of this single-visit apexification treatment supports the contention that frequent changing of the calcium hydroxide dressing is not always required to induce apical closure.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
3/23. Management of a horizontal root fracture after previous root canal therapy.This case report concerns a 9-year-old girl who had a horizontal root fracture of her maxillary left central incisor and had root canal therapy performed by her family dentist immediately after the injury. Because of the incomplete canal obturation, the root canal filling material was removed, and calcium hydroxide therapy was initiated. Healing at the fracture site occurred, with hard tissue forming between the root segments. The coronal segment of the root was then obturated with gutta-percha. The patient later had orthodontic treatment with some movement of the coronal segment. Six-year post-treatment follow-up shows apparent clinical and radiographic success. This case illustrates the potential for repair of a horizontal root fracture after endodontic retreatment of the coronal segment and long-term splinting.- - - - - - - - - - ranking = 7keywords = canal (Clic here for more details about this article) |
4/23. Enhanced post crown retention in resin composite-reinforced, compromised, root-filled teeth: a case report.The introduction of an intraradicular composite reinforcing technique, in conjunction with the reestablishment of matching post canal spaces, has allowed compromised, root-filled teeth to be restored with functional, esthetic post crowns. This clinical case report suggests that reconstituted post canals, in accurately adapting to passive, parallel-sided, matching, and well-fitting posts, can enhance the retention of post crowns. Other factors of clinical importance relating to the resin-reinforced technique are discussed, including fracture resistance, depth of polymerization, dentin adhesion, polymerization shrinkage, and coronal microleakage.- - - - - - - - - - ranking = 2keywords = canal (Clic here for more details about this article) |
5/23. Treatment of cariously involved fused maxillary primary lateral and central incisors.A 3-and-a-half-year-old male child presented with fused cariously involved right maxillary primary central and lateral incisors as well as a previously traumatized non-vital left primary central incisor with a draining fistula. The child also had other restorative needs and the decision taken was to address all needs under a G.A. With respect to the fused incisors, these were split and root canals treatment was performed for all three incisors which were then restored with stainless steel crowns with esthetic facings.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
6/23. Unusual tooth sensation due to maxillary sinusitis--a case report.maxillary sinusitis can cause pain or discomfort to the maxillary dentition but no report of patients complaining of a "jumping tooth sensation" during sinusitis has been recorded in the literature. This article presents a case of an unusual localised sensation from a maxillary right second premolar experienced while undergoing root canal treatment. This sensation was felt during walking while the patient was suffering an episode of influenza. This sensation first occurred following debridement of the root canal. However, it persisted even after the root canal had been sealed. A hypothetical explanation of this manifestation is proposed.- - - - - - - - - - ranking = 3keywords = canal (Clic here for more details about this article) |
7/23. Retrieval of a foreign object from the palatal root canal of a permanent maxillary first molar: A case report.A 12-year-old boy presented with a fractured sewing needle within the palatal root canal of a nonvital permanent maxillary first molar. The patient admitted that he had often placed a sewing needle in the tooth to relieve discomfort associated with it. A minimal amount of tooth structure was removed around the foreign object to facilitate access for K-type files. Under copious irrigation, the files were worked around the object to loosen it. The fractured needle was removed with a tweezers that had long, narrow beaks. Use of this simple technique allowed the object to be removed from the root canal with minimal damage to internal tooth structure.- - - - - - - - - - ranking = 6keywords = canal (Clic here for more details about this article) |
8/23. Use of anatomic post and core for reconstructing an endodontically treated tooth: a case report.A clinical case is presented in which a new type of fiber post was used in combination with the proprietary dual-curing resin cement to bond in a wide, nonrounded root canal. The anatomic post was inserted and the relining resin photopolymerized. The anatomic post was then removed and a luting procedure was performed, as for any other translucent post. The clinical procedure was simple, and a superior fit to the root canal walls was achieved, thus reducing the amount of cement needed. The luting procedure described can be proposed as a clinical technique for routine use when the prepared root canal is too wide or not perfectly round.- - - - - - - - - - ranking = 3keywords = canal (Clic here for more details about this article) |
9/23. Restoration of endodontically treated teeth without posts.PURPOSE: To describe the treatment of a patient with a dismal oral situation after successful cure for drug addiction. methods: After root canal treatment and surgical pretreatment, four maxillary glass-fiber reinforced composite fixed partial dentures, anchored by endo-crowns instead of post and core, were fabricated (Targis & Vectris). Additionally, full crowns on four dental implants and an inlay were produced of non-reinforced composite (Targis). All restorations were luted adhesively to abutments with a three component adhesive system (Syntac Classic), light-curing composite (Tetric) and an ultrasonic insertion technique. RESULTS: An esthetic and functional acceptable result was achieved. Excessive removal of tooth structure by post preparation may weaken the root.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
10/23. Aesthetic restoration of the compromised root: a case report.The amount of tooth structure that remains after endodontic therapy and post preparation is of prime importance as the strength and resistance to root fracture of an endodontically treated tooth is directly related to the amount of residual dentine. The desired post diameter is determined by tooth morphology and the endodontic procedures (for root canal debridement) with the aim being to avoid removing too much tooth structure. Increasing the diameter of the post does not provide a significant increase in the retention of the post; it only increases the stiffness of the post at the expense of the remaining dentine and the fracture resistance of the root. There is little indication for increasing the post width beyond the endodontic cleaning and shaping procedures for all post systems. The post diameter needs to be controlled to preserve the radicular dentine, reduce the potential for perforations, and permit the tooth to resist fracture. However, endodontic treatment often involves wide flared canals where cast posts are the standard method of treatment. These thin-walled canals are then further compromised by the placement of a tapered cast post--thus increasing its risk for fracturing. The Luminex light, transmitting posts provide an alternative treatment option by strengthening weakened, endodontically treated teeth by the combined bonding action of dentine bonding agents and composite resin restorative material. The paper reports on a case where a wide flared root canal was rehabilitated with composite resin using a light-transmitting post.- - - - - - - - - - ranking = 4keywords = canal (Clic here for more details about this article) |
