When enamel surface is viewed under the microscope, shallow furrows called perikymata are seen. These are likely to be due to • Abrasion from tooth brush • Attrition from occlusal forces • Cracks (lamellae) in enamel • Incremental formation of enamel • Organic (protein) deposits from the saliva • The following cells are found in the periodontal ligament: • A. Fibroblasts • B. Epithelial cell rests of Malassez • C. Ameloblasts • D. Odontoblasts • E. C and D • F. A and B • Cementoblasts differentiate from the following cell population: • A. Outer Enamel epithelium • B. Inner enamel epithelium • C. Dental papilla • D. Dental follicle • E. Stellate reticulum

Step 1
- Perikymata are shallow furrows on the enamel surface that are due to the incremental formation of enamel. This is a natural process during tooth development. Answer: Incremental formation of enamel Step 2: Identify the cells found in the periodontal Show more…
