Case of bilateral non-Hodgkin's lymphoma after dental extractions in a patient with the human immunodeficiency virus.

It has long been known that immunocompromised patients have an increased risk of getting malignant neoplasms, with lymphomas predominating. This increase in lymphomas is especially notable in the population infected with the human immunodeficiency virus (HIV). Before the outbreak of the human immunodeficiency virus these neoplasms rarely occurred in the maxillofacial region; they are now being seen with a greater frequency. This report details a case of bilateral non-Hodgkin's lymphoma that was initially misdiagnosed as an odontogenic infection.

Pathohistology of undecalcified primary teeth in vitamin D-resistant rickets: review and report of two cases.

The basic dental defects in vitamin D-resistant rickets seem to be manifested in dentin. Enamel is usually reported to be normal. This histologic examination showed the penetration of microorganisms through the calcified structures of the enamel layer without visible caries. The microorganisms passed through the dentinoenamel junction and invaded dentin, which was characterized by calcospherites and large amounts of interglobular dentin. Furthermore, microorganisms could be detected in dentinal tubules, which were exposed to the oral cavity when enamel was removed. However, large areas of tertiary dentin extended between such tubules and the pulp. These light microscopic results suggest that clinical manifestations, such as, pulp recrosis and periapical lesions (without carious defects) may be caused by the penetration of microorganisms through microclefts of the enamel layer as well as pathologically altered enamel microstructures of affected teeth.

The palato-gingival groove. A cause of failure in root canal treatment.

The authors describe a clinical case of a palato-gingival groove on a maxillary central incisor with associated localized periodontal disease and pulp necrosis. The general clinician's initial diagnosis was incorrect; this led to incomplete treatment and subsequent loss of the tooth. Recognition of the palato-gingival groove is critical, especially because of its diagnostic complexity and the problems that may arise if it is not properly interpreted and treated.

Giant cementoblastoma simulating a peridental infection.

A case of giant cementoblastoma of the maxilla in a young female is reported. An unusual painful swelling of the gingivolabial area led to an initial misdiagnosis of a peridental infection and consequently to inappropriate treatment.

Tongue piercing and associated oral and dental complications.

The insertion of metal objects into intraoral and perioral sites is growing in popularity. However, there are numerous oral and dental complications associated with tongue piercing. Fifteen patients with tongue piercings (pierced in the body of the tongue, anterior to the lingual frenum) attending the dental office of the authors, with and without complaints, were clinically and radiographically examined. The most common dental problem registered was chipping of teeth. Furthermore, two cracked teeth and four teeth with cusp fractures were also seen. One case of selective dental abrasion was registered. Trauma to the lingual anterior gingiva was the most common gingival problem. A salivary flow stimulating effect was only reported by 2 of the 15 individuals. None of the patients complained of interference with speech, mastication and swallowing. One case of galvanic currents produced by the appliance was registered. On the basis of the registered data, we concluded that patients need to be better informed of the potential complications associated with tongue and oral piercings, and that the dental profession can serve this role.

Treatment of combined endodontic-periodontic lesions by intentional replantation and application of hydroxyapatites.

A case of combined endodontic-periodontic lesions on a mandibular first molar was treated by intentional replantation and application of hydroxyapatites. Four months after the surgery, a porcelain-mental full crown restoration was completed. The 15-month follow-up examination showed that the tooth was clinically and radiographically healthy and functioned well.

Treatment of a non-vital immature incisor with mineral trioxide aggregate (MTA).

- A case of severe crown fracture and luxation in the upper permanent incisors of a 9-year-old boy is reported. The treatment of one of the injured teeth included apexification with calcium hydroxide and endodontic treatment with gutta-percha obturation. The other incisor was also treated with calcium hydroxide, but as there was no apical stop after 3 years of treatment, it was decided to use a new root-end filling material: mineral trioxide aggregate (MTA). At follow-up 12 months later, the tooth was asymptomatic and radiographically showed the initial repair of the radiolucent apical lesion.

Mortality associated with odontogenic infection!

Odontogenic causes are the most common source for spreading maxillo-facial infections. These infections can develop into life threatening events. However a fatal outcome is fortunately rare and is generally associated with an immunocompromised status. This case report highlights a spreading maxillo-facial infection, which resulted in massive haemorrhage from the subclavian vein into the pleural cavity and subsequent death of a young fit male patient.
