| Potential complications associated with long-term steroid use are atrophy, steroid-induced acne, rosacea, and striae. |
| The labial and lingual surfaces are either more or less smooth, or covered with fine anastomosing striae. |
| The annulae show a transverse growth striation, the striae being 0.01-0.05 mm wide. |
| The striae ridges are broad and bifurcate both apically and basally, and the grooves are narrow and sharp. |
| The latter is covered by the indusium griseum, a thin sheet of rudimentary cortex containing the delicate medial and lateral longitudinal striae. |
| Close examination reveals a reticulated pattern of white scale known as Wickham's striae. |
