Simultaneous presentation of focal cemento-osseous dysplasia and simple bone cyst of the mandible masquerading as a multilocular radiolucency.

The fibro-osseous lesions represent a large group of disorders that have many common characteristics including clinical, radiographic and microscopic features. Although most are of unknown aetiology, some are believed to be neoplastic and others are related to metabolic imbalances. It is not unusual to see these lesions presenting with a range of radiographic appearances, causing considerable diagnostic confusion owing to their similar histology. This case report presents a histologically benign cemento-osseous lesion that is radiographically consistent with a focal cemento-osseous dysplasia, along with a concomitant simple (traumatic) bone cyst within the right mandibular alveolus, with the initial presentation as a multilocular radiolucency. Pertinent literature is reviewed.

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.

Dens evaginatus and dens invaginatus in a maxillary lateral incisor: report of a rare occurrence and review of literature.

A case of dens evaginatus (DE) and dens invaginatus (DI) concurrently affecting the maxillary right permanent lateral incisor in a 25-year-old Hispanic male is reported. DE, referred to as Talon's cusp in the anterior teeth and Leong's premolar in the premolar teeth, is a relatively rare condition by itself. An association of DI with this rare anomaly within the same tooth has never been reported before although it has been known to occur within the same patient. Since it is known that DE may be composed of normal enamel and dentine, as well as varying amounts of pulpal tissue, care should be exercised while performing any aesthetic procedures to remove or recontour it.

Radiographic diagnosis of Limbus vertebra on a lateral cephalometric film: report of a case.

Although Limbus vertebra is not an uncommon radiological finding in an adult, it is a rare finding in the child or adolescent. The most common site for the presence of Limbus vertebra is the mid-lumbar region and less commonly occurs in the mid cervical region. It is a defect (tiny unfused apophyseal fragment) in the anterior margin of the vertebral body usually at the superior anterior margin in the lumbar vertebrae and at the anteroinferior margin in the cervical vertebrae. These margins are the sites of epiphyseal centers on vertebrae. A case of Limbus vertebra seen on a routine lateral cephalometric radiograph taken prior to Orthodontic treatment is reported and the literature is reviewed. The Limbus vertebra is thought to result from herniation of the nucleus pulposus through the ring apophysis prior to fusion isolating a small segment of the vertebral rim. This could be mistaken for a fracture, infection or tumor resulting in further invasive diagnostic procedures. It is important to recognize that this represents the sequela of a remote injury in an immature skeleton. A sound knowledge of this anomaly is essential for all clinicians so that appropriate measures can be taken without unduly alarming patients.

Bilateral calcifications secondary to synthetic soft tissue augmentation of the cheeks: report of a case.

Although esthetic soft tissue augmentation of the cheeks has been in practice for over a century, calcifications associated with the soft tissue substitutes were rarely reported. A case demonstrating bilateral concentric opacities in the soft tissues of the cheek secondary to cheek augmentation is presented. The opacities were detected accidentally during routine intraoral radiographic examination. This condition initially posed a challenge in radiographic diagnosis in the absence of adequate history and clinical information. In this report we have briefly reviewed different types of implant materials used for soft tissue augmentation. We believe that inflammation of the tissues adjacent to the implant material is possibly responsible for the development of calcifications associated with esthetic soft tissue augmentations.

Patterns of intra-osseous transmigration and ectopic eruption of mandibular canines: review of literature and report of nine additional cases.

OBJECTIVES: The purpose of this study is to (1). investigate the patterns of transmigration and eruption of permanent mandibular canines, plus the mechanisms affecting the eruption path, (2). classify the transmigration paths. MATERIAL AND METHODS: :A retrospective radiographic study using full mouth (FMX) and panoramic radiographs of dental radiology patients between July 1996 and July 2000. Transmigrated canines were identified from the radiographic records of 2150 new patients. The literature was reviewed regarding the individual patterns of canine transmigration and their final position within the mandible. A pattern classification was developed using literature data and the additional nine cases reported here. RESULTS: In the present study, mandibular canines were found transmigrated on nine occasions and, in a further six cases, found impacted without transmigration. Out of the nine cases, seven were female (ages 17-38) and two were male (ages 20 and 69). One female patient had a bilateral transmigration of the mandibular canines. A total of 127 transmigrated canines were reported in 50 published studies from the literature. Transmigrated canines appear to fall into five patterns (Type 1-5) depending on their path of deviation. Type 1 was most common (45.6%) followed by Type 2 (20%), Type 4(17%), Type 3(14%) and Type 5 (1.5%). CONCLUSIONS: Patterns of mandibular canine transmigration can be classified into five distinct patterns. The majority of cases demonstrated Type 1 transmigratory pattern. No clear aetiology of this disorder could be found.

Synovial chondromatosis of the temporomandibular joint with extension to the middle cranial fossa.

A rare case of synovial chondromatosis with extension to the middle cranial fossa is reported. Synovial chondromatosis, a benign disorder characterized by multiple cartilaginous, free-floating nodules that originate from the synovial membrane is not exclusive to the temporomandibular joint (TMJ). This condition is commonly seen in the axial skeleton and can involve multiple joints. In this case, synovial chondromatosis of the TMJ led to complete bony erosion of the glenoid fossa extending into the middle cranial fossa. Although plain radiographs showed the involvement of the joint, Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) provided more detailed information about the lesion in all three dimensions. This case demonstrates the value of CT and MRI in both the diagnosis and treatment planning. A review of previously reported cases of synovial chondromatosis with cranial extensions is included.
