Enamel defects in primary canines related to traditional treatment of teething problems in Sudan

In parts of Sudan and some other countries, teething is thought to be the cause of severe health problems in infants, and a traditional treatment involves lancing the alveolar process over the unerupted canines with a heated needle, a procedure known as 'haifat'. Three hundred and ninety-eight children aged 4-8 years were examined for the presence of enamel defects on primary canines, and their parents or guardians were questioned regarding past teething problems and their treatment. Two hundred and fifty-eight (65%) of the children had experienced health problems that had been attributed to teething, and 89 (22%) had been subjected to 'haifat'. 'Haifat' had been practised by all socio-economic groups, but was most prevalent in the lower groups. Enamel defects on the buccal surface of the primary canines were found in 25 (28%) of the children in the 'haifat' group and in 25 (8%) of the other children.
