Brownish lines, the striae of Retzius, develop as a result of a change in the growth process. Macroscopically, these lines can be seen on the labial surface or lip side of anterior or front teeth as horizontal lines on the tooth crown, also known as perikymata or "imbrication lines" .
Why are enamel tufts formed?
Their formation has been attributed to stress and are considered a form of defect. However, stress upon the enamel is not needed to produce them since they occur in impacted third molars that are not affected by biting forces.
