Twenty-one cases of transposition are presented showing a crude prevalence of 0.4%. A high rate of bilateral occurrence was seen. A significant number of cases were associated with other dental anomalies, such as peg-shaped lateral incisors and overretained deciduous teeth. Genetic etiology has been stressed and various other theories discussed.

This case report presented a rare case of irreversible ectopic eruption of right mandibular first permanent molar in a 6-year-old boy. Distal root resorption of primary second molar was found during routine radiographic examination. Early treatment of ectopically erupting permanent first molar was considered in favor of preventing space loss. ...

A rare case of dens invaginatus involving a non-carious mandibular lateral incisor with periapical periodontitis is reported. Invaginated teeth present technical difficulties in their clinical management because of their abnormal anatomy. In the present case, non-surgical root canal therapy was chosen. A one-year follow-up clinical and radiographic examination showed a ...

Ectopic eruption of teeth can occur in a wide variety of sites. These include the mandibular condyle, coronoid process, palate, nasal cavity and maxillary sinus. While this process is unusual, the detection of a third molar in the maxillary antrum is extremely rare. A case is presented of ectopic eruption ...
Prabhu N T - - 1995
The case of a patient with an additional distal root in each permanent mandibular first molar is reported. A thorough review of the dental literature failed to reveal any significant data concerning such cases because much of the literature is concerned with variation in root canal morphology rather than variations ...
Hou G L - - 1995
Supernumerary teeth are relatively common in the maxillary incisor and molar areas. However, bilateral ectopic, fully erupted supernumerary mesiodentes are relatively rare. The present case documents a patient with localized periodontitis of the maxillary first and second molars associated with bilaterally erupted supernumerary teeth located in proximity to the buccal ...

A case of Y-shaped lower bilateral central incisors found in an 18-year-old Japanese man is reported. Each of the central incisors had an abnormally high cusp located at the labial surface. The cause of this malformation of the lower central incisors is obscure, but we suspect that it was due ...
Majourau A - - 1995
Severe impaction of lower second molars often leads to their extraction to avoid potential damage to the first molar root. We present a case in which we used the clinical application of simple biomechanical principles to allow us to upright bilaterally impacted lower second molars into the desired location in ...

A six-year-old boy presented with extraoral eruption of a mandibular permanent canine and a loosely attached lateral incisor in the labial vestibule, 3 months following trauma to the chin. The trauma not only caused displacement of the permanent tooth buds, but also resulted in transposition of the lateral incisor and ...

In some patients, primary molars with no permanent successor can be retained for an indefinite time; however, if occlusal relationships necessitate intraocclusal augmentation, cast ceramic onlays can provide an excellent solution. This paper reports the case of a teenager in whom two cast ceramic onlays were bonded with resin to ...
Ford G S - - 1994
External root resorption is a multifactorial process with many causes. Except for transient surface resorption, it is usually considered an irreversible process. Treatment can arrest or retard the resorptive process. Many factors that have been associated with this process include physiologic resorption, local factors, systemic conditions, and idiopathic resorption. This ...
Dawoodbhoy I - - 1994
A case of an 8-year-old boy who met with a road traffic accident causing trauma to the body and face and extrusion of the upper central incisors is reported. Laceration, oedema and limited mouth opening indicated the use of general anesthesia. During intubation the right central was avulsed accidentally and ...

BACKGROUND: Periosteal fasciitis is rare in the head and neck. We believe only two cases of fasciitis-induced erosion through the mandibular cortical plate have previously been reported. RESULTS: Management of a case of periosteal fasciitis with bone erosion at the mandibular angle is reported in a 38-year-old man. CONCLUSIONS: Misdiagnosis ...

When conventional endodontic treatment or retreatment is not possible, the operator may choose to intentionally extract and replant the involved tooth. Intentional replantation consists of extracting the tooth, finding and correcting the defect, and replanting the tooth in its socket. This article discusses the indications, contraindications, and recommended techniques for ...

Two cases of hypoglossia congenita with anterior maxillo-mandibular fusion are reported. One is a case of hypoglossia with anterior maxillo-mandibular fusion and the other is a case of hypoglossia-hypodactylia with anterior maxillo-mandibular fusion. This condition presents the anaesthetist with the problem of airway management during the surgery. A simple technique ...

Dens in dente (dens invaginatus, tooth within a tooth, dilated composite odontome) is an abnormal tooth form which occurs most frequently in the permanent maxillary lateral incisor region. Dens in dente may occur, however, in any tooth in the dental arch, although these other forms are comparatively rare. It may ...
Darbar U R - - 1993
A case of a patient with multiple external root resorption affecting principally the molars and premolars is described. This case is unusual in that although both right and left molar and premolar teeth are involved, the resorption is worse on the left side and affects only the distal roots of ...

There is some controversy about whether or not tooth preparation is needed before placing porcelain laminate veneers. Without adequate preparation, the added surface contour may increase the risk of periodontal disease. When properly executed, veneers for cosmetic dentistry should be reversible. Many teeth that could have been saved with the ...
