1/100. Surgical treatment of a periradicular lesion on an invaginated maxillary lateral incisor (dens in dente). The complex anatomy of invaginated teeth make their root canal treatment difficult. Moreover, this treatment may compromise the future of the tooth if it is destined to support a post-retained coronal restoration. This case reports the successful surgical root canal treatment of an invaginated tooth using a retrograde filling with gutta-percha. After surgical exposure of the root-end and cleaning of the root canal, the gutta-percha was compacted in the root canal which had been coated previously with a zinc oxide-eugenol cement. The gutta-percha was then cold-burnished. Periapical radiographic examination after 1, 2, 3, 6 and 12 months showed periapical healing with osseous formation. This procedure, resulting in minimal loss of hard tissues, permitted subsequent restoration of the tooth. ( info) |
2/100. Endodontic treatment of immature tooth with dens invaginatus: a case report. The endodontic treatment of a dens invaginatus in an immature permanent upper lateral incisor of a 9-year-old boy is presented. Root canal treatment was performed using calcium hydroxide paste as a temporary root canal filling in order to achieve apexification. This was replaced after closure of the apex with a final root canal filling using gutta-percha and AH 26 as the sealer. The follow-up radiographic control demonstrated the effectiveness of nonsurgical treatment in a case of incomplete root formation in a tooth with dens invaginatus. ( info) |
3/100. Dens invaginatus in the maxillary lateral incisor: treatment of 3 cases. Nonsurgical treatment of 3 maxillary lateral incisors with dens invaginatus is reported. Invaginated teeth present technical difficulties with respect to their management because of complicated canal morphology. In the first case reported, apical abscess with incomplete root formation was found at the time of examination. calcium hydroxide apexification provided favorable conditions for root closure and obturation. The other 2 cases were treated by conventional root canal treatment. Follow-up examinations showed successful clinical results, with osseous healing evident radiographically. ( info) |
4/100. Complex treatment of dens invaginatus type III in maxillary lateral incisor. The complex anatomy and diagnosis of dens invaginatus make endodontic treatment of such teeth difficult. This case describes combined nonsurgical and surgical treatment of a maxillary lateral incisor with a normally shaped canal and a dens invaginatus type III with a lateroradicular lesion. The root canal was treated conventionally with gutta-percha and a zinc oxide-eugenol sealer. The root was surgically exposed and the canal of the dens invaginatus was cleaned, instrumented and obturated with gutta-percha and a zinc oxide-eugenol sealer. At follow-up 3 years 6 months later, the tooth was asymptomatic and radiographically showed repair of the lesion in the region of the dens invaginatus. ( info) |
5/100. Unusual case of bilateral talon cusp associated with dens invaginatus. CASE REPORT: This paper presents a rare case of bilateral talon cusp in permanent maxillary central incisors, one on the labial and another on the lingual surface of each tooth. The condition was associated with dens invaginatus in a maxillary permanent lateral incisor, but no developmental syndrome was identified. The left central incisor required no treatment because the aesthetic appearance was satisfactory and neither occlusal interferences nor caries were present. After careful investigation of the right lateral incisor, a sealant was applied. Root canal treatment was indicated for the right central incisor that had a wide open apex with thin, weak, divergent walls, and an apical radiolucency. ( info) |
6/100. Root canal treatment of an invaginated maxillary lateral incisor with a C-shaped canal. The endodontic treatment of an atypical maxillary lateral incisor that contained a C-shaped root canal is described. The unusual anatomic configuration of this particular tooth and the advantage of using image magnification to facilitate endodontic treatment are discussed. ( info) |
7/100. Maxillary lateral incisor with two root canals: fusion, gemination or dens invaginatus? Endodontic retreatment of a maxillary right lateral incisor with two root canals is described. The diagnosis of fusion, gemination or dens invaginatus could not be made, due to conflicting findings, and to previous root canal treatment that erased the original configuration of the pulp chamber.

8/100. Endodontic, surgical and periodontal treatment of dens invaginatus. Case report. The aim of this paper is to propose a single stage global treatment of endodontic, periapical and periodontal lesions in a lateral maxillary incisor with dens invaginatus. A 24 year-old woman presenting a lateral maxillary incisor with dens invaginatus in association with periapica1 and periodontal lesions underwent simultaneous surgical, endodontic and periodontal regenerative procedures. At 2, 6, 12, 18 months follow-up the radiographic healing appeared to be improved and the periapical lesion healed completely 1 year after surgical intervention. Surgery in association with endodontic and periodontal procedures represents the treatment of choice to maximize long term prognosis in cases of dens invaginatus with chronic periapical and periodontal lesions.

10/100. Non-surgical root canal treatment of dens invaginatus type 2 in a maxillary lateral incisor. AIM: To describe the clinical management of an unusual dens invaginatus type 2. SUMMARY: A case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. The patient presented with pain and localized swelling. Despite the complex anatomy and diagnosis of dens invaginatus, non-surgical root canal treatment was performed successfully. Key learning points Dens invaginatus may be presented in many forms, and the aetiology of this phenomenon is not fully understood. Due to abnormal anatomical configuration, dens invaginatus presents technical difficulties in its clinical management. Non-surgical root canal treatment can be performed successfully. ( info) |
