Which teeth have Perikymata?
Perikymata are the expression of striae of Retzius at the surface of enamel. They can be found on all teeth, but are usually the easiest to notice on anterior teeth (incisors and canines).
What is dental Perikymata?
Perikymata are wavelike features that are normally found in the surface enamel of teeth. These structures are known to undergo regressive changes due to gradual attrition, mechanical abrasion, or chemical erosion.
Which teeth have Imbrication lines?
imbrication n. Anterior teeth in the same arch which overlap each other. Imbrication lines are mesio-distal ridges on the cervical third of the labial surface of an anterior tooth associated with enamel incremental growth formation. …
What type of teeth have Mamelons?
Mamelons are the small bumps on your four front teeth called incisors. They usually appear as a group of three and wear down as you age. Mamelons don’t need any special treatment.
Do primary teeth have perikymata?
Primary dentition, proximal views. Usually, there are no depressions, mamelons, or perikymata on the labial or incisal surfaces of the crowns of the primary incisors. These surfaces are smoother than on their successors.
How is perikymata formed?
The appositional secretion process of the enamel during its histogenesis creates a series of striations on the surface of the dental crown in the form of grooves known as Perikymata (Simmer & Hu, 2001). The term perikymata is derived from the Greek words ‘wave’ (Cortés & Ureña, 2011).
What are perikymata and imbrication lines?
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” .
Which tooth has largest cingulum?
The wedge-shaped outline of the crown shows the canine to have greater labiolingual bulk than any other anterior tooth. The greatest measurement labiolingually is at the cervical third. This is because of the huge cingulum of the lingual side and the more convex labial outline of the canine.
Can braces fix mamelons teeth?

What causes horizontal ridges in teeth?
Dental Disease The condition is the result of disturbances to the ameloblasts in their enamel matrix production. Enamel hypoplasia results in the development of horizontal ridges, giving the teeth a ribbed or ‘washboard’ appearance.
