1/15. Mandibular and maxillary furcation tunnel preparations--literature review and a case report.AIM: The objective of this literature review and subsequent case report is to discuss and illustrate the tunnel preparation procedure as a treatment alternative for furcation-involved molars. review OF THE literature: Furcation tunnel preparation, i.e., the creation of access for plaque control between periodontally diseased roots, has not been discussed in the literature as comprehensively as root resective therapy, though success rates appear to fall within the same range. A short root trunk and a wide furcation entrance diameter are prerequisites for the indication of the tunnel preparation procedure. Although accessory canals in the furcation area are frequent findings on extracted teeth, endodontic complications have not been reported to be major complications after tunnel preparation. Caries developed at tunneled teeth even under proper maintenance, but did not necessarily lead to the loss of an affected tooth. CASE REPORT: In the case presented to illustrate the indication for the tunnel preparation procedure, periodontal disease was almost entirely restricted to the furcation sites of molar teeth. Affected teeth were either extracted or left intact and subjected to tunneling procedures. Periodontal health could be established and maintained at both single and double tunnels over a period of 2 years of periodontal supportive therapy.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
2/15. Root-canal treatment of a trifid crown premolar.AIM: To describe successful root-canal treatment of a permanent maxillary first premolar with unusual anatomy. SUMMARY: A diagnosis of irreversible pulpitis of a geminated first premolar was made. Clinical and radiographic examination revealed a tooth with a trifid crown that joined to give the appearance of a single root at the cementoenamel junction. Root-canal treatment involved three separate access openings and treating four canals, three of which joined to exit through a common foramen. KEY learning POINTS: Symptomatic teeth with morphological aberrations can be saved by root-canal treatment.Careful clinical and radiographic evaluation are essential, as treatment must be modified to address the unusual complexities of the root-canal system(s).- - - - - - - - - - ranking = 9keywords = canal (Clic here for more details about this article) |
3/15. Endodontic treatment of developmental anomalies in posterior teeth: treatment of geminated/fused teeth--report of two cases.AIM: Gemination or fusion is a rare occurrence in the mandibular posterior teeth. Endodontic treatment of these teeth needs special care and attention to the bizarre anatomy. The aim of this article is to describe the problems encountered and the strategy in treating such cases. CASE REPORT: Two cases of complex endodontic treatment of fused/geminated teeth are presented. The first is an 11-year-old girl with an anomalous 'double' first mandibular molar and premolar diagnosed as having necrotic pulp with chronic apical abscess of endodontic origin; the second is a 16-year-old boy with 'double' second and supernumerary mandibular molars, who was diagnosed with irreversible pulpitis. Both cases were treated successfully in multiple appointments. The common features and treatment modalities are discussed. KEY learning POINTS: Failure to diagnose fused/geminated teeth leads to misdiagnosis and a treatment plan that could cause permanent damage and tooth loss. Generally, there is communication between root canal systems of fused/geminated teeth which should be treated as one entity. Use of magnification is an important aid during treatment.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
4/15. diagnosis and root canal treatment of a mandibular second premolar with three root canals.AIM: To present a case of a mandibular second premolar with three root canals. SUMMARY: An accurate diagnosis of the morphology of the root canal system is a prerequisite for successful root canal treatment. A review of the literature reveals a low incidence of all types of premolars with three root canals. Diagnostic means such as preoperative radiographs and examination of the pulp chamber floor aid the location of root canal orifices. The diagnostic and therapeutic problems concerning premolars with unusual anatomy are described on the basis of a clinical example. A case report describes the successful treatment of a mandibular second premolar with three root canals. KEY learning POINTS: Clinicians should be aware of unusual root canal anatomy in mandibular premolars. Radiographs exposed at two different horizontal angles and their careful interpretation facilitate the search of additional root canals. The use of magnification and additional lighting are recommended for the clinical examination of the pulpal floor.- - - - - - - - - - ranking = 16keywords = canal (Clic here for more details about this article) |
5/15. Resolution of furcation bone loss associated with vital pulp tissue after nonsurgical root canal treatment of three-rooted mandibular molars: a case report of identical twins.This case report demonstrates the simultaneous development of furcation bone loss in three-rooted tooth #30 with vital pulp tissue in identical twins. In the first report, resolution of furcal bone loss was seen after nonsurgical root canal treatment. In the second report, furcal bone loss resolved after non-surgical root canal treatment, and periodontal therapy reduced probing depths to maintainable levels.- - - - - - - - - - ranking = 6keywords = canal (Clic here for more details about this article) |
6/15. Endodontic therapy in a mandibular second bicuspid with four canals.Success in endodontic therapy often depends on the removal of the critical concentration of pulp tissue or necrotic debris within the root canal system. The best method to ensure this objective is to locate and instrument all of the canals in the root of the tooth. Therefore, a thorough knowledge of root canal morphology is essential to reduce the chances of failure. The purpose of this article is to report a case of mandibular second bicuspid with four distinct canals.- - - - - - - - - - ranking = 8keywords = canal (Clic here for more details about this article) |
7/15. Endodontic therapy of traumatized incisors with crown and transverse intra-alveolar root fractures.A case involving traumatic injury to the maxillary anterior teeth with crown and transverse intra-alveolar root fractures is reported. The patient did not seek immediate treatment after trauma. Treatment included pulpectomy, fixation of a fractured root, root canal obturation, endodontic therapy of the coronal segment, and postoperative observation. Follow-up showed good results. Thus effective nonsurgical endodontic therapy of traumatized anterior teeth can result in a good prognosis in cases involving crown and intra-alveolar root fractures.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
8/15. Inflammatory resorption caused by an adjacent necrotic tooth.A case history is presented with a large periapical lesion and a perforating resorption defect on a cuspid. Endodontic therapy was performed, presuming that the necrotic cuspid caused the inflammatory response. No radiographic healing was evident 18 months after endodontic therapy. Considerable healing was demonstrated 6 months later, following the extraction of an adjacent tooth with prior root canal therapy. It was concluded that the failing root canal therapy of the extracted tooth was the primary factor leading to the inflammatory lesion, the resorptive perforation of the adjacent tooth, and its pulpal necrosis. It has not been reported prior that inflammatory resorption can result from the pulpal necrosis of an adjacent tooth.- - - - - - - - - - ranking = 2keywords = canal (Clic here for more details about this article) |
9/15. Periodontal repair of periapical lesions: the borderland between pulpal and periodontal disease.A series of cases demonstrating the destruction of periapical periodontal structures, without pulpal involvement has been presented. Treatment using both surgery and antibiotics resulted in extensive healing without any concommitant endodontic therapy. The results suggest that lesions affecting the apical periodontium are either periodontal or pulpal in origin. Careful diagnosis allows the maintenance of pulp vitality in cases where apical destruction has a source other than an infected pulp. The commonly held belief that lateral and accessory canals are a significant source of pulpal contamination from deep periodontal pockets has been questioned.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
10/15. Pseudocyst of the maxillary sinus.A case report is presented involving the endodontic retreatment of a maxillary second molar associated with a sinus radiopacity. Disappearance of sinus pathosis occurred within 6 days after root canal debridement. A direct relationship between apical pathosis and a pseudocyst of the maxillary sinus is suggested. Thirteen-month recall shows no recurrence.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
