Sickle cell hemoglobinopathy is an inherited disorder characterized by vasoocclusive crises. Involvement of the maxillofacial skeleton leading to radiopaque lesions that correspond to bone infarcts has rarely been reported in the literature. Forty-two adult patients suffering from sickle cell anemia were examined radiographically for radiopaque lesions situated in the course of a known vessel or in the apical region of the teeth. In 6 cases, such lesions were combined with facial pain during sickle cell crisis and absence of dental pathology and were considered to be of possible vasoocclusive origin. In conclusion, vasoocclusive involvement should be taken into consideration when assessing painful episodes or neurological symptoms in the maxillofacial region in this patient population.

The purpose of this study was to determine the distribution of tooth transpositions in a sample of orthodontic patients, describe the accompanying anomalies and report on the management and therapeutic outcome. Overall, the male to female ratio was 4:3, left side predominance was evident, and there was a high incidence of associated dental anomalies. Attempts to correct tooth order usually resulted in untoward effects on periodontal tissues. Consequently, individual anatomical conditions may be decisive in successful clinical management of such cases.

Elevated values of LDH, ALT and AST in serum do not constitute a confounding factor in GCF measurements of the respective enzymes.
