RESUMO
The effect of iron deficiency maintained for over 6 months on the pigmentation and structure of incisors was investigated in female white rats. Gross loss of pigmentation was observed. Sections revealed enamel hypoplasia and aplasia. Dentinogenesis was much less affected, but there were areas of altered dentine with abnormal tubules and increased thickness of predentine with cellular and vascular inclusions.

A questionnaire was used to assess the attitude of family members in Jordan to the state of their teeth, their personal oral hygiene and their acceptance of dental care. The questions were formulated to provide information without the need for dental examination. In industrial societies there is evidence of a reduction in the rate of dental decay whereas in countries such as Jordan the reverse is true. Consideration of this trend, in combination with the results of this survey, provides a strong indication that instruction in oral hygiene must be given together with increased facilities for treatment.
