1/12. Treatment of root perforation by intentional reimplantation: a case report.Intentional reimplantation is defined as a procedure in which an intentional tooth extraction is performed followed by reinsertion of the extracted tooth into its own alveolus. In this paper, intentional reimplantation is described and discussed as a treatment approach to root canal instrument separation in conjunction with root perforation. An 8-year follow-up case report is presented. The reimplanted tooth is now a fixed bridge abutment. Although successful in this case, the intentional reimplantation procedure should be considered a treatment of last resort, that is, when another treatment option is not viable for the treatment of root perforation/instrument retrieval.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
2/12. Bone-like tissue growth in the root canal of immature permanent teeth after traumatic injuries.Following a severe traumatic incident to permanent immature teeth, the growth of calcified tissue in the pulp space may occasionally occur. This calcified tissue may be diffuse or in intimate contact with the dentine. It has been suggested that a wide open apex, severe damage to the root sheath, and the absence of infection are only some of the predisposing factors leading to this metaplasia of pulp tissue into bone-like tissue. Five cases are described.- - - - - - - - - - ranking = 4keywords = canal (Clic here for more details about this article) |
3/12. Cemental tear: a case report.AIM: To report a case of a cemental tear. SUMMARY: A case is reported of a patient with a history of trauma, root canal treatment and retreatment procedures to eliminate recurring sinus tracts. An exploratory surgery, extraction, and biopsy resulted in a diagnosis of cemental tear. KEY learning POINTS: * The detachment of a fragment of cementum is described as a cemental tear. * Cemental tears have been reported in the periodontal literature associated with localized, rapid periodontal breakdown. Common causative factors are aging and traumatic occlusion but the exact aetiology is unknown. * Trauma may be considered as a potential aetiologic factor for cemental tears in addition to occlusal traumatism and aging.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
4/12. Management of the perforations due to miniplate application.Microdimensioned osteosynthesis using miniplates has been common practice in maxillofacial surgery. However, tooth injury during the application of the miniplates have been reported in few papers. In this case, a 32-yr-old female patient, whose two teeth were necrosed because of the perforation during screw insertion was presented. The reason of the perforations during the rigid internal fixation was the lack of radiographic assessment because of the pregnancy. Maxillary right first premolar and maxillary left canine were perforated and necrosed because of the screw insertion. The necrosed teeth were detected 1 yr after the rigid internal fixation. The root canals of nonvital teeth were filed using step-down approach. Cold lateral condensation of gutta-percha was used to fill the canals. Six-month recall visits were scheduled and there was no problem after 2-yr follow-up period.- - - - - - - - - - ranking = 2keywords = canal (Clic here for more details about this article) |
5/12. Treatment of pulp floor and stripping perforation by mineral trioxide aggregate.Mineral trioxide aggregate (MTA) has been widely used to repair various kinds of tooth perforations, but its use for obturation of the entire root canal has not been reported. We report two cases of tooth perforation successfully repaired with MTA. The first patient was a 78-year-old male with calcified canal and pulp floor perforation in the left maxillary first premolar. After bypass of the calcified palatal canal, both buccal and palatal canals were filled with gutta percha, and the pulp floor perforation was repaired with MTA. Clinical success with no evident radicular lesion was found at the 18-month follow-up. The second patient was a 51-year-old female with a stripping perforation in a C-shaped root canal of the right mandibular second molar detected after removal of a post. Following root canal debridement and calcium hydroxide therapy to control inflammation at the stripping perforation site, apical and furcation bone healing were observed by radiographic examination. The stripping perforation was repaired by obturation of the entire C-shaped root canal with MTA. observation at the 9-month follow-up revealed bone healing without any clinical symptoms and signs. These cases suggest that MTA is an alternative root canal obturation material for treatment of stripping perforation in a C-shaped root canal and for repair of pulp floor perforation.- - - - - - - - - - ranking = 9keywords = canal (Clic here for more details about this article) |
6/12. Surgical repositioning of traumatically intruded permanent incisor: case report with a 10-year follow up.This report describes the case of a 10-year-old boy that was referred to the pediatric dentistry clinic 15 days after sustaining a severe traumatism that led to complete intrusion of the maxillary left mature permanent central incisor. The intruded tooth was repositioned by using surgical extrusion. Endodontic therapy was performed with calcium hydroxide-based paste as root canal dressing and root canal filling was performed with a calcium hydroxide-based root sealer and gutta-percha points. The postoperative course was uncomplicated, with both clinical and radiographic success up to 10 years of follow up. In this case surgical repositioning combined with endodontic therapy constituted a viable alternative treatment for intrusive luxations in mature permanent teeth.- - - - - - - - - - ranking = 2keywords = canal (Clic here for more details about this article) |
7/12. Treatment of lateral root perforation with mineral trioxide aggregate: a case report.Root perforations are undesired complications of endodontic treatment which result in loss of integrity of the root and further destruction of the adjacent periodontal tissues. In recent literature mineral trioxide aggregate (MTA) has been regarded as an ideal material for perforation repair. In this case iatrogenic perforation was observed in a maxillary central incisor. It was not possible to reach the perforation from the access cavity due to the angulation and excessive bleeding even though the root canal was filled with calcium hydroxide paste between appointments. Therefore, surgical intervention was preferred. After the root canal was filled with gutta percha and AH plus, the perforation site was subsequently sealed with MTA. The restoration was made with strip crown and composite resin. The symptoms were ceased and the results were satisfactory after 15 months follow-up.- - - - - - - - - - ranking = 2keywords = canal (Clic here for more details about this article) |
8/12. dental pulp response to traumatic injuries--a retrospective analysis with case reports.The reactions of the dental pulp to traumatic injuries can be extremely varied. They range from almost immediate pulp death to long-term slow pulp canal calcification. In this study the pulpal reactions were divided into three types: pulps with a very poor prognosis that required endodontic therapy soon after the tooth was traumatized. Seventy-nine teeth were studied in this category, and all 79 teeth required endodontic therapy; pulps with a moderate prognosis that required endodontic intervention some 18 to 24 months after the traumatic episode. Forty-eight teeth were studied in this category, and 27 of them required endodontic therapy: pulps with a very good prognosis that rarely required endodontic therapy. Fifty-two teeth were studied in this category, and only 2 required endodontic therapy. The prognosis of a particular pulp depends on the degree and type of trauma.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
9/12. Combining reconstructive and regenerative therapies.The authors used combined reconstructive and regenerative therapy to treat a patient who had a surgically created osseous defect that also was associated with a perforated root canal. The defect involved a maxillary canine that exhibited 10 millimeters of attachment loss on its mesial surface. tetracycline root surface conditioning, glass ionomer cement, a decalcified freeze-dried bone allograft and an expanded-polytetrafluorethylene membrane were used to achieve a 7- to 8-mm gain in clinical attachment level two years after the initial surgery. This case illustrates the use of glass ionomer cement, in conjunction with regenerative therapy, to effectively treat a root perforation adjacent to a periodontal osseous defect.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
10/12. A root perforation and treatment.According to Lemon (1992) the internal matrix concept of repairing perforations has distinct advantages over the surgical method. The procedure is more time-efficient when compared with other methods. The technique requires direct access and visualization of the perforation site in order to place the repair material. It is therefore restricted to perforations in the furcation area, and the straight portions of the root canal.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
