This article reports a case of a maxillary second premolar which on presentation was partially erupted, and which resisted attempts at orthodontic extrusion. The crown of the tooth was eventually restored using an adhesive composite onlay technique. The patient subsequently complained of pain and the root of the tooth showed ...

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 ...

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 ...

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 ...

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 case is reported in which an intruded incisor was initially treated by an endodontic dressing with calcium hydroxide and then extruded using a removable orthodontic appliance.

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 ...

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 ...

It is considered that benign cementoblastoma continues to be an infrequent entity that particularly affects young patients under the age of 30. The sex ...

The history of intracoronal bleaching and the development of the walking bleach technique are reviewed. External cervical resorption associated with intracoronal bleaching is a serious sequela that has been reported in the literature. One explanation given for this phenomenon is that it results from an inflammatory process initiated by the ...

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 ...

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 ...

The purpose of this study involving a sample of children with single central incisor crossbite was to determine the relationship between clinical crown lengths of the crossbite and noncrossbite mandibular incisors, incisor irregularity, and orthodontic correction of the crossbite. In addition, for comparison, the normal maturational change in position of ...

This is the case report of a 26-year-old black woman with a Class I malocclusion and a skeletal Class II profile and vertical maxillary excess.

Posttreatment retention and subsequent observation is recorded with photographic results seven years after the completion of active treatment with the Begg Appliance.

The causes of tooth impaction are as numerous as are ways to manage the problem. Treatment is usually instituted only after an unfavourable eruption prognosis of the impacted tooth has been established from radiographic and clinical examination. Advantages of guided eruption and surgical removal have to be weighed. Fifteen cases ...

The loss of anterior teeth by trauma has usually been corrected by orthodontic or prosthetic means. In some specific cases, however, the skeletal and dental relationship may contraindicate the use of space-closure mechanics. Autotransplantation of teeth, successfully depicted in many clinical studies, can help to reduce the severity of orthodontic ...

A case report about the orthodontic treatment of a Class III malocclusion in a black man 22 years 8 months old.
