Berglund L - - 1996
Impacted maxillary canines in oblique horizontal positions may make orthodontic appliance treatment hazardous or impossible. Autotransplantation may be considered but the removal of the canine is often difficult and since atraumatic removal of the transplant is essential, autotransplantation is then impossible. A new possibility is orthodontic pre-treatment with distal and ...

The aim of this study was to evaluate clinically and radiographically the long-term results of endodontic therapy. A total of 172 mature teeth with periapical radiolucencies with and without symptoms were treated endodontically using calcium hydroxide paste as the intracanal medicament and a calcium hydroxide containing root canal sealer. In ...

Once referred to as "flyer's toothache," barodontalgia is defined as tooth pain occurring with changes in ambient pressure. It usually occurs in people who fly or dive. It can develop in conjunction with sinusitis, and in teeth experiencing pulpitis after restorative treatment, new and recurrent caries, intra-treatment endodontic symptoms, dental ...
Otero-Cagide F J - - 1996
This report describes 9 cases presenting exostosis at mandibular and maxillary sites where autogenous gingival grafts have been used to increase the amount of attached gingiva. The exostoses were recognized during routine dental examinations and identified by palpation, horizontal sounding, occlusal radiographs, and in one case by histologic examination. Only ...

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.

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 ...

Mandibular anterior ceramic veneers, though used less frequently than maxillary anterior ceramic veneers, are highly useful for certain case conditions. The learning objective of this article is to explore the indications, tooth preparation design, provisionalization considerations, and placement procedures for these conservative aesthetic restorations. In addition, their functional utility, tissue ...

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 ...

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 ...
