ABSTRACT
BACKGROUND: The transmigration of a mandibular canine is a rare phenomenon, the etiology of which is not clear. The literature on this rare condition is reviewed, and six cases of transmigrated mandibular canines are presented. REPORT: Panoramic radiographic examination of six patients revealed each patient had one impacted transmigrated mandibular canine. Of the six impacted teeth, the left mandibular canine was involved in four instances and the right in two. In one case the transmigrated canine was associated with a dentigerous cyst. SUMMARY: Transmigration of the mandibular canine is a rare event, and early radiographic examination of the patient is important for treatment. In addition, future studies may lead to a better understanding of this rare anomaly and improvement of the classification criteria.

Fanconi's anaemia (FA) is an autosomal recessive disorder that is clinically characterized by aplastic anaemia, congenital malformations of the renal, cardiac, skeletal and skin structures, and an increased predisposition to malignancies. Patients with FA often present with bleeding and infection, which are symptoms related to thrombocytopenia and neutropenia. There are few reports of the oral manifestations of FA. We describe oral aphthous ulcerations in two siblings with FA. There was a rapid improvement and healing of ulcers after blood transfusions and increased haemoglobin levels. This may support the role of severe anaemia in oral ulcerations.

BACKGROUND: There are four key studies in the periodontology literature reporting the correlation between supernumerary teeth and aggressive periodontitis. The aim of this study is to detect such a relationship. METHODS: Patients with supernumerary teeth were identified retrospectively from their orthopantomographs and were invited to the periodontology department for intraoral examination. They were then evaluated for aggressive periodontitis. The number of existing teeth, age, family histories, attachment loss, probing depths, and bleeding on probing scores were recorded. RESULTS: Of the 5,850 subjects randomly observed among 48,000 patients, only 174 exhibited supernumerary teeth. Of these 174 subjects, only three patients were diagnosed with aggressive periodontitis. One of the patients was also suffering from Fanconi's anemia. CONCLUSIONS: Despite the similarities (aggressive periodontitis accompanied by supernumerary teeth) in the previous reports, we do not agree with the earlier results. We rather suggest that this association might be a random occurrence, rather than a biological one, although this observation should be further investigated using genetic testing.
