1/6. Endodontic treatment of teeth associated with a large periapical lesion.AIM: To report the healing of a large periapical lesion following non-surgical root canal treatment. SUMMARY: A 12-year-old male with a large periapical lesion around the apices of his mandibular incisors is described. The lesion formed after trauma to the mandibular anterior teeth 5 years previously. During root canal treatment, chlorhexidine gluconate was used for irrigation, and calcium hydroxide was used both for the intracanal dressing and as a base of the root canal sealer. Periapical healing was observed 3 months after obturation and continued at the 12-month review. Key learning points Root canal treatment, including the use of chlorhexidine gluconate and calcium hydroxide for infection control, led to substantial healing of a large periapical lesion. This report confirms that large periapical lesions can respond favourably to non-surgical treatment.- - - - - - - - - - ranking = 1keywords = seal (Clic here for more details about this article) |
2/6. Revascularization of immature permanent teeth with apical periodontitis: new treatment protocol?A new technique is presented to revascularize immature permanent teeth with apical periodontitis. The canal is disinfected with copious irrigation and a combination of three antibiotics. After the disinfection protocol is complete, the apex is mechanically irritated to initiate bleeding into the canal to produce a blood clot to the level of the cemento-enamel junction. The double seal of the coronal access is then made. In this case, the combination of a disinfected canal, a matrix into which new tissue could grow, and an effective coronal seal appears to have produced the environment necessary for successful revascularization.- - - - - - - - - - ranking = 2keywords = seal (Clic here for more details about this article) |
3/6. Treatment of invasive cervical resorption with MTA: case report.This paper presents a case report of a maxillary lateral incisor affected by invasive cervical resorption. The tooth was submitted to a 21-day treatment with calcium hydroxide followed by root canal filling. The area of resorption was sealed with MTA followed by glass ionomer cement and restored with composite resin. Two-year radiographic follow-up showed stability of the resorption site and normal coronal colour and depth of gingival sulcus.- - - - - - - - - - ranking = 1keywords = seal (Clic here for more details about this article) |
4/6. Acute pulpal-alveolar cellulitis syndrome. V. Apical closure of immature teeth by infection control: the importance of an endodontic seal with therapeutic factors. Part 2.During orthodontic treatment to promote eruption of maxillary and mandibular second bicuspids, a young male patient had a severe endodontic cellulitis of a mandibular bicuspid. Apexogenesis and resolution of the periapical lesion was achieved by infection control with nonspecific intracanal medication without calcium hydroxide, as stated by Das. A mild periodontal cellulitis occurred shortly thereafter and rapidly resolved. A second endodontic cellulitis, after apexogenesis without an endodontic seal, occurred shortly after completion of orthodontic treatment. This also quickly resolved, and the canal was effectively sealed. This case indicates the importance of an effective endodontic seal shortly after apexogenesis is induced by infection control. This report and others on the subject indicate that apexogenesis of nonvital permanent immature teeth by infection control is a predictable endodontic treatment procedure.- - - - - - - - - - ranking = 7keywords = seal (Clic here for more details about this article) |
5/6. Surgical extrusion of a completely intruded permanent incisor.This report presents a case of a completely intrusive luxation of a mature permanent central incisor in a 10-yr-old boy. The intruded tooth was repositioned by using surgical extrusion and stabilization with interdental sutures. Endodontic treatment was performed with calcium hydroxide paste as the intracanal medication and a calcium hydroxide-based root canal sealer. This treatment mode was observed at 18 months and was successful at that time.- - - - - - - - - - ranking = 1keywords = seal (Clic here for more details about this article) |
6/6. Pre-eruptive intracoronal lesion of a mandibular first molar.A patient developed an acute apical abscess on a mandibular first molar with an intact occlusal sealant. Radiographs reveal no typical patterns of decay on occlusal or proximal surfaces. An unusual lesion within dentin and an apparent extension from it to the external tooth surface are visible on films at the time of onset of symptoms as well as prior to eruption. Possible explanations for the lesion and its progression are discussed.- - - - - - - - - - ranking = 1keywords = seal (Clic here for more details about this article) |
