1/14. Severe gingival recession in trisomy 18 primary dentition. A clinicopathologic case report of self-inflicted injury associated with mental retardation.This clinicopathologic case report documents severe gingival recession in the primary dentition of a trisomy 18 patient. Primary molar and canine teeth exhibited recession extending beyond the midpoint of the buccal aspect of the root, occasionally reaching the root apex. Radiographic examination revealed taurodontism in both primary and permanent teeth. Clinical and histopathologic findings, along with case history, eliminated the possibility of prepubertal periodontitis and suggested a diagnosis of self-inflicted injury associated with mental retardation. Histologic examination of the primary teeth revealed normal cementum and dentin structure. Taurodontism, histologic structure of the dentition, and severe attachment loss in the primary dentition have not been described previously in trisomy 18.- - - - - - - - - - ranking = 1keywords = periodontitis (Clic here for more details about this article) |
2/14. rothmund-thomson syndrome: a case report.rothmund-thomson syndrome (RTS) is an extremely rare genetic disorder characterized by poikilodermatous skin changes, photosensitivity, and an increased risk of developing skin and bone malignancies. In this case report, the dental and periodontal features of RTS in a 16-year-old female patient are presented. The transmission electron microscopy performed on a gingival biopsy specimen showed structural defects of connective tissue. If the unusual ultrastructural findings of this case are confirmed as being consistent with other RTS patients, it is our opinion that this syndrome can be considered among the systemic diseases associated with early-onset periodontitis.- - - - - - - - - - ranking = 1keywords = periodontitis (Clic here for more details about this article) |
3/14. Talon cusp causing occlusal trauma and acute apical periodontitis: report of a case.- The talon cusp, or dens evaginatus of anterior teeth, is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cemento-enamel junction. This occurs in either maxillary or mandibular anterior teeth in both the primary and permanent dentition. One of the main problems caused by accessory cusps are occlusal interferences. The anomalous cusp even can generate occlusal trauma and reversible acute apical periodontitis of the opposing tooth. This article reports a case of talon cusp affecting the permanent maxillary left lateral incisor that caused clinical problems related to occlusal trauma and apical periodontitis caused by a premature contact. The treatment of the occlusal interference produced by the taloned tooth is described.- - - - - - - - - - ranking = 6keywords = periodontitis (Clic here for more details about this article) |
4/14. Fractured dens evaginatus and unusual periapical radiolucency.Dens evaginatus (DE) is not uncommon. It can affect the premolars of people of oriental ethnicity, and it can lead to different clinical problems. This article describes the diagnosis and management of a patient presenting with a fractured tubercle of DE and an unusual buccal abscess in relation to periapical radiolucency extending around the mandibular second premolar and first molar.- - - - - - - - - - ranking = 1.4556982785707keywords = periapical (Clic here for more details about this article) |
5/14. Long-term occlusal guidance of a severely intoxicated patient with yusho (PCB poisoning): a case report.The peculiar dentoorofacial characteristics and 12 years of interdisciplinary management of a patient who was severely intoxicated with the man-made chemical polychlorinated biphenyls (PCBs) are described in this case report. Cephalometric measurements showed that the SNA and SNB angles were reduced but that the developments in height and skeletal maturity were in normal ranges. Gingival hyperpigmentation that was caused by high blood PCB concentration was extremely slow to fade. A cystic mass, diffused trabeculae, and irregular calcification, which were shown on the radiograph and which were caused by high blood levels of PCB, changed gradually. However, the patient had periodontal disease because of horizontal alveolar bone resorption and a deep periodontal pocket, despite good plaque control. After the PCB poisoning the tooth roots were hypoplastic and dilacerated. One root was extracted because of chronic periodontitis. Some teeth were impacted, malposed, or ankylosed.- - - - - - - - - - ranking = 1keywords = periodontitis (Clic here for more details about this article) |
6/14. Facial cellulitis arising from dens evaginatus: a case report.Dens evaginatus is a developmental anomaly that produces a tubercle on the occlusal surface of a tooth. It is found most frequently in the mandibular premolars. The occlusal tubercle easily causes occlusal interferences. Attrition or fracture of the tubercle can lead to pulpitis, pulp necrosis, periapical pathosis, and periapical infection. This case report illustrates the treatment of facial cellulitis arising from dens evaginatus with open apex. calcium hydroxide was used for the apexification procedure. One year after canal obturation, radiography revealed no apical pathosis and the apical seal was evident.- - - - - - - - - - ranking = 0.58227931142828keywords = periapical (Clic here for more details about this article) |
7/14. Complex facial radicular groove in a maxillary lateral incisor.A case report of a developmental anomaly known as a radicular groove is presented. This case is unusual in that it is believed to be the first reported case of complex involvement of the entire facial aspect of a tooth root. An alveolar crest to apex facial root defect in a maxillary right lateral incisor of a 12-yr-old black female led to early pulpal necrosis and periapical rarefaction. Clinical and histologic findings as well as morphologic and treatment ramifications are discussed.- - - - - - - - - - ranking = 0.29113965571414keywords = periapical (Clic here for more details about this article) |
8/14. Nonsurgical endodontic treatment of a tooth with double dens in dente.A case of "double" dens in dente with an open apex and periapical lesion is reported. Nonsurgical endodontic treatment was performed. The canals were medicated for 5 months with calcium hydroxide before obturation with combined sectional and thermoplasticized warm gutta-percha. Follow-up revealed an asymptomatic patient and a reduction in size of the periapical lesion.- - - - - - - - - - ranking = 0.58227931142828keywords = periapical (Clic here for more details about this article) |
9/14. Radiographic observations of pyknodysostosis. Report of a case.A case of pyknodysostosis in a 32-year-old woman has been reported. The patient presented typical skeletal changes, separated cranial sutures, open fontanelles, partial aplasia of the terminal phalanges of the fingers and toes, and brachyphalanges. The oral findings included lesions resembling periapical cementoma, hypoplasia of the maxilla and mandible, crowding of teeth, and a median raphe.- - - - - - - - - - ranking = 0.29113965571414keywords = periapical (Clic here for more details about this article) |
10/14. Bilateral dens invaginatus in the mandibular incisor region.A case of bilateral dens invaginatus in the mandibular incisor regions has been reported. Radiographs demonstrated invaginations in both of the incisors in the mandibular incisor region and also demonstrated a periapical radiolucency. Clinical examination revealed two anomalous incisors and apparently there was congenital absence of two mandibular incisors. Dens invaginatus in the mandibular incisors would appear to be a most unusual occurrence.- - - - - - - - - - ranking = 0.29113965571414keywords = periapical (Clic here for more details about this article) |
