1/27. Microscopic removal of dens invaginatus.Endodontic treatment for teeth that exhibit the dental anomaly, dens invaginatus, can be difficult due to the bizarre anatomy and relative inaccessibility of the diseased pulp tissue. Surgical intervention or extraction are common approaches to dealing with this condition. This article reports the treatment of an extreme form of dens invaginatus, employing the dental-operating microscope and the ultrasonic instrument. Removal of the entire anomalous structure and pulp tissue was possible, and conventional orthograde obturation was accomplished. Two and 4-yr follow-up radiographs show that healing has occurred. The article demonstrates that the anomalous structure of dens invaginatus is a separate entity from the rest of the tooth. This implies that in many instances it may be entirely removed to facilitate conventional endodontic therapy.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
2/27. Dens invaginatus type III: report of a case and 10-year radiographic follow-up.AIM: The purpose of this article is to report the 10-year follow-up of a right mandibular central incisor with 'dens invaginatus' that was root filled. SUMMARY: 'Dens invaginatus' is a rare malformation of teeth, probably resulting from an infolding of the dental papilla during tooth development. It has alternatively been called 'dens in dente' and 'dilated composite odontome'. Radiographic examination may clearly demonstrate this feature, although no signs may be recognized clinically. If no entrance to the invagination can be detected and there are no signs of pulp pathosis, then no treatment is required other than fissure sealing of the invagination. In deep invaginations, it is likely that root-canal treatment may be required. Occasionally, when the tooth has an immature root, apexification is necessary. Root-canal treatment of a right mandibular central incisor with 'dens invaginatus' is described along with 10-year follow-up. KEY learning POINTS: Both clinical and radiographic examinations are necessary to determine morphological features of teeth before root-canal treatment. Sensibility testing to determine the pulp condition is critical prior to treatment.- - - - - - - - - - ranking = 0.5keywords = dental (Clic here for more details about this article) |
3/27. Multiple dental anomalies in the maxillary incisor region.A patient with multiple anomalies of the maxillary teeth, including shovel-shaped incisors, talon cusp, bilateral dens invaginatus and bilateral peg-shaped supernumerary incisors is reported. The patient also exhibited Carabelli's cusp on both maxillary first molars. No developmental syndrome was identified. This very unusual combination of anomalies has not been reported previously.- - - - - - - - - - ranking = 2keywords = dental (Clic here for more details about this article) |
4/27. Double dens invaginatus of molarized maxillary central incisors, premolarization of maxillary lateral incisors, multituberculism of the mandibular incisors, canines and first premolar, and sensorineural hearing loss.Molarization and premolarization of anterior teeth have never been reported before. Double dens invaginatus is an extremely rare condition. We describe an affected female who had developmental delay and congenital progressive sensorineural hearing loss. Double dens invaginatus of molarized maxillary central incisors and premolarized maxillary lateral incisors were present. In addition, multituberculated mandibular incisors, canines, and first premolar were observed. Histologically, tooth structure was unremarkable. family history of dental abnormalities and hearing loss was denied. Clinical and radiographic examinations were those performed when the patient was 7 and 13 years old. The basic defect is postulated to be of mesenchymal origin.- - - - - - - - - - ranking = 0.5keywords = dental (Clic here for more details about this article) |
5/27. Maxillary cyst associated with an invaginated tooth: a case report and literature review.Dental invagination or dens in dente is a rare malformation with a widely varied morphology. Radiographically, the affected tooth shows an infolding of the enamel and dentin that can extend to within the pulp cavity and the root and sometimes to the root apex. It can occur in both primary and permanent teeth, and its prevalence is reported to be 1.7% to 10%. The dental anomalies observed in association with dental invagination include taurodontia, microdontia, supernumerary teeth, gemination, and dentinogenesis imperfecta. This article presents a clinical case in which a radiographic finding could be compatible with the presence of a nasopalatine or globulomaxillary cyst and a dens in dente. It was decided to extract the invaginated tooth, and by 15 days postextraction, the radiolucid area had completely disappeared. The complex surgery that would have been required to remove the patient's supposed cyst was thus avoided. Clinical and radiographic examination is suggested before making further decisions that could complicate treatment when a lesion is associated with other dental anomalies.- - - - - - - - - - ranking = 1.5keywords = dental (Clic here for more details about this article) |
6/27. dens in dente (dens invaginatus). Report of two unilateral and one bilateral case.Dens invaginatus is a deep surface invagination of the crown or root that is lined by enamel. It is one of the developmental anomalies affecting the teeth. It commonly affects maxillary lateral incisor, followed by central incisor, premolar, canine and molar tooth. Maxillary teeth are more commonly involved than mandibular teeth. It usually occurs unilaterally although 43% occur bilaterally. The invagination within the tooth can be single, double and even triple has been reported. The affected tooth usually is thick, barrel shaped with a small round palatal opening to the invagination. It usually traps plaque, food debris and is prone for dental caries, which may lead to pulpal and periapical pathology. So if detected early the dens invaginatus should be prophylatically restored. Two unilateral and one bilateral case of dens invaginatus are reported here.- - - - - - - - - - ranking = 0.5keywords = dental (Clic here for more details about this article) |
7/27. Endodontic treatment of dens invaginatus type III with three root canals and open apical foramen.AIM: To describe the conservative endodontic treatment and the 1-year follow-up of a permanent maxillary lateral incisor with dens invaginatus. SUMMARY: Frequently, the root canal treatment of invaginated teeth is challenging because of problems associated with gaining access to the root canals and with variations of canal morphology associated with this type of malformation. The present case describes the complex root canal treatment of dens invaginatus in a maxillary lateral incisor with three root canals (Oehler type III), incomplete apex formation, necrotic pulp and abscess formation. After gaining access to two root canals and the invagination with the help of a dental operating-microscope, the canals and the invagination were instrumented and calcium hydroxide dressing was applied for 6 months. apexification and osseous bone repair were achieved, and the canals were filled with gutta-percha. A follow-up after 1 year showed that the tooth was free of any clinical symptoms and the periapical condition was normal. KEY learning POINTS: The present case demonstrated that conservative root canal treatment can be performed successfully even in sever cases of dens invaginatus. The use of a dental operating microscope can help in the management of complicated cases of invaginated teeth through conventional root canal treatment.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
8/27. A rare presentation of dens invaginatus in a mandibular lateral incisor occurring concurrently with bilateral maxillary dens invaginatus: case report and review of literature.BACKGROUND: Dens Invaginatus (DI), commonly known as dens in dente, is a developmental malformation of tooth that most commonly affects permanent maxillary lateral incisor teeth. Deciduous teeth are infrequently affected. Presence of DI in mandibular permanent teeth is extremely rare. Further, the presence of DI bilaterally in the maxillary lateral incisors of the same patient is even more unusual. methods: In this article, an unusual case of DI affecting a mandibular lateral incisor tooth is described. This malformation was uncovered after a full mouth radiographic examination when the patient presented for dental treatment unrelated to this finding. In addition, the various radiographic appearances of DI as they present within the maxillary and mandibular teeth are described. Essential clinical considerations and treatment options are presented. A review of the pertinent literature is undertaken and a table summarizing previous published findings of mandibular DI is presented. RESULTS: A review of the literature indicates that DI in mandibular teeth is extremely rare with only 10 other cases involving 13 teeth reported previously. CONCLUSIONS: Although this is an extremely rare case, DI is an anomaly that should be familiar to all practising dentists due to the clinical implications of potential sequelae of pulpal involvement.- - - - - - - - - - ranking = 0.5keywords = dental (Clic here for more details about this article) |
9/27. Endodontic treatment of an invaginated maxillary lateral incisor with a periradicular lesion and a healthy pulp.AIM: To report the healing of a periradicular lesion following nonsurgical root canal treatment of a dental invagination. SUMMARY: A case of dens invaginatus type 3 with a periradicular lesion and a healthy pulp is reported. Nonsurgical root canal treatment of the invagination was performed successfully and resolved an associated periradicular lesion. Despite the complex anatomy and a diagnosis of apical periodontitis, pulp health was retained after endodontic treatment of the invaginated canal. Clinical considerations and treatment are discussed and reported. KEY learning POINTS: Dens invaginatus can present in a variety of forms, knowledge of which can usefully inform endodontic diagnosis and treatment. In certain cases, success can be achieved by treating the invagination alone. Pulp health may be preserved during and after treatment of an infected invagination.- - - - - - - - - - ranking = 0.5keywords = dental (Clic here for more details about this article) |
10/27. Management of two unusual cases of dens invaginatus and talon cusp associated with other dental anomalies.The management of two unusual cases of dens invaginatus and talon cusp is presented. The first concerns talon cusp in maxillary primary and permanent lateral incisors, a supplemental tooth with dens invaginatus hampering eruption of the permanent incisors. The other present with bizarre crown morphology of a lateral incisor with talon cusp, dens invaginatus and a palatal accessory cusp-like structure. early diagnosis and management are important to avoid complications.- - - - - - - - - - ranking = 2keywords = dental (Clic here for more details about this article) |
